Recently there was a major discovery in the scientific research—the mapping of all DNA in a human gene(基因) is complete.Couple of years ago, this seems an impossible task for scientist to accomplish.All this progress in science leads us to believe that the day, when the human being will be cloned, is not far away.Human cloning has always been a topic of argument, in terms of morality or religion.
Taking a look at why cloning might be beneficial, among many cases, it is arguable that parents who are known to be at risk of passing a genetic limitation to a child could make use of cloning.If the clone was free of genetic limitations.then the other clone would be as well.The latter could foe inserted in the woman and allowed to ripen to term.Moreover, cloning would enable women, who can't get pregnant, to have children of their own.
Cloning humans would also mean that organs could be cloned, so it would be a source of perfect transfer organs.This, surely would be greatly beneficial to millions of unfortunate people around the world that are expected to lose their lives due to failure of single (or more) organ (s).It is also arguable that a ban on cloning may be unlawful and would rob people of the right to reproduce and limit the freedom of scientists.
Arguments against cloning are also on a perfectly practical side.Primarily, I believe that cloning would step in the normal "cycle" of life.There would be a large number of same genes, which reduce the chances of improvement, and, in turn, development—the fundamental reason how living things naturally adapt to the ever-changing environment.Life processes failing to do so might result in untimely disappearance.Furthermore, cloning would make the uniqueness that each one of us possesses disappear.Thus, leading to creation of genetically engineered groups of people for specific purposes and, chances are, that those individuals would be regarded as "objects" rather than people in the society.
Scientists haven't 100 per cent.guaranteed that the first cloned humans will be normal.Thus this could result in introduction of additional limitations in the human "gene-pool".
Regarding such arguable topics in "black or white" approach seems very innocent to me personally.We should rather try to look at all "shades" of it.I believe that cloning is only legal if its purpose is for cloning organs; not humans.Then we could regard this as for "saving life" instead of "creating life".I believe cloning humans is morally and socially unacceptable.
小題1:Which of the following is true according to the passage?
A.Genetic limitation will be beneficial for some women
B.A large number of genes will prevent us from developing
C.Prohibition of cloning might limit the freedom of scientists
D.First cloned humans might be normal according to scientists
小題2:What's the author's opinion on cloning?
A.Cloning should be entirely banned.
B.Cloning should be used in creating life.
C.Cloning will take away the right to reproduce.
D.Cloning is acceptable if it is used for cloning organs.
小題3:Where can you read this article?
A.In a story book
B.In a magazine
C.In a science fiction

小題4:A

試題分析:最近在科學研究方面有了大的發(fā)現(xiàn)---人類基因的完整圖譜。這一重大發(fā)現(xiàn)使人們相信克隆人的那一天不在遙遠。克隆人一直受到爭議,從道德和宗教方面來說。但是克隆人有好處:一是使那些不孕不育的女性有自己的孩子;二是可以用來克隆器官。但是克隆人使人不在具有唯一性,而且也不能保證正常。所以,克隆器官可以被接受?寺∪藷o論從道德上還是社會上都不能被接受。
小題1:推理判斷題。根據(jù)倒數(shù)第二段的意思:科學家到現(xiàn)在還不能確定第一批克隆人是否正常,這樣就會限制科學家在人類基因方面的研究增加限制。故選C 。
小題2:推理判斷題。根據(jù)最后一段的I believe that cloning is only legal if its purpose is for cloning organs; not humans.(我認為克隆是合法的,如果目的是克隆器官而不是人。)。由此判斷選擇D。
小題3:推理判斷題。通讀全文判斷,文章是對克隆人的優(yōu)點和缺點作了分析,不是選自故事書,也不是科幻小說,更不是小冊子,推斷B(雜志)最佳。
小題4:結(jié)構(gòu)分析題。全文各段的內(nèi)容分析:第一段闡明觀點,第2、3、4、5分別再具體說明觀點,最后一段總結(jié)。由此判斷A最佳。

Dear Mayor,
I would like to draw your attention to the depressing state of the environment in our city. Increased vehicles have made the air polluted. Citizens find it difficult to breathe. Dumping toxic chemicals into the river has polluted the drinking water and ground water.
All of us, as concerned citizens, have discussed these problems in various meetings. We have come up with the following proposals(提議).
The green roads are no longer green. Many trees and bushes have been cut. We propose restricting the movement of vehicles. Besides, we should make it compulsory(強制性的)to use anti-pollution devices on all vehicles. We should also plant more plants and trees along roads.
The Bada Nadi River has become a dumping ground of toxic chemicals from some factories. These toxic chemicals have killed nearly all the life in the river and polluted our drinking water and ground water. We propose that the Bada Nadi River be declared a protected water body. All the dumping should be banned and heavy fine should be imposed on the offenders(違法者). To tackle the problem of managing toxic waste, we propose setting up a water treatment plant so that only clean water is discharged into the river. Cleaning up the river and introducing various fishes and plants to the river will bring it back to life.
Lastly, the noise pollution caused by honking(鳴)horns and blaring loudspeakers has caused distress to one and all. Many people have suffered from noise-related illnesses. We propose a blanket ban on the use of loudspeakers. And“no horn zones”should also be declared in residential hospitals and school areas.
I would request you to seriously consider our proposals and act accordingly.
Thank you!
Sincerely yours,
A kind-hearted citizen

As soon as I saw her, I understood I was in trouble. The tiny 10-year-old girl was staring at me with that specific facial expression which probably only dentists have to enjoy all day long!
Whatever question I asked, whatever activity I suggested, her reaction was pretty much the same — she was frozen with horror. She was sent to our private language school after having been the worst in English at her key school with a pretty strict ELT syllabus(教學大綱), with her peers teasing her for her mistakes in English. Moreover, her state school teacher called her name. To make things worse, she was under pressure from her family for getting bad marks in English. She was definitely expecting me to carry on the same way with her.
I have to admit that I had been staring at her with probably the same expression for a while before eventually she handed in an absolutely incredible composition which I had previously asked the class to write. It was written in perfect handwriting, was full of clever ideas and had correct paragraphing. The girl got her first excellent mark in English, and I praised her generously and from then on I started using her writing skills to support the others. Before doing an oral retelling of a story, she wrote it down. Before presenting her oral project, she was allowed to do the same thing. The day she first put up her hand to orally answer my question addressed to the class I was incredibly happy.
She taught me how to approach withdrawn students — find the skill which they can excel at, in her case writing, and help the student use it to develop other skills!
小題1:The writer is probably a teacher    
A.in a language training center
B.in a private language school
C.in a state school
D.in a key public school
小題2:The writer’s first impression of the little girl was that she was    
A.incredibly dullB.hard to cope with
C.far too lovelyD.pretty confident
小題3:The girl came to the school because

Antidepressant(抗憂郁)drugs such as Prozac were viewed in the early 1900's as wonder pills that would remove depressive blues for good. But in the past five years, growing scientific evidence has shown these drugs work for only a minority of people. And now a research journal says that these antidepressants can make many patients' depression worse. This alarming suggestion centres on the very chemical that is targeted by antidepressants-serotonin(血清素). Drugs such as Prozac are known as selective serotonin re-uptake inhibitors(or SSRIs). Their aim is to increase the level of this  “feel-good” chemical in the brain.
But the new research, published in the journal Frontiers In Evolutionary Psychology, points out that serotonin is like a chemical Swiss Army knife, performing a very wide range of jobs in the brain and body. And when we start changing serotonin levels purposely, it may cause a wide range of unwanted effects. These can include digestive problems and even early deaths in older people, according to the study's lead researcher Paul Andrews. “ We need to be much more cautious about use of these drugs,” says Andrews, an assistant professor of evolutionary psychology at McMaster University in Ontario, Canada.
Previous research has suggested that the drugs provide little benefit for most people with mild depression, and actively help only a few of the most severely depressed. Famous psychologist Irving Kirsch has found that for many patients, SSRIs are no more effective than a placebo pill. A research in 2010 on Danish children found a small, but significant, increase in the risk of heart problems among babies whose mothers had used SSRIs in early pregnancy. The key to understanding these side-effects is serotonin, says Andrews. Serotonin is also the reason why patients can often end up feeling still more depressed after they have finished a course of SSRI drugs. He argues that SSRI antidepressants disturb the brain, leaving the patient an even greater depression than before.
“After long use, when a patient stops taking SSRIs, the brain will lower its levels of serotonin production,” he says, adding that it also changes the way receptors in the brain respond to serotonin, making the brain less sensitive to the chemical. These changes are believed to be temporary, but studies indicate that the effects may continue for up to two years.
Most disturbingly of all, Andrews' review features three recent studies which, he says , show that elderly antidepressant users are more likely to die earlier than non-users, even after taking other important variables into account. One study, published in the British Medical Journal last year, found patients given SSRIs were more than 4 per cent more likely to die in the next year than those not on the drugs.
“Serotonin is an ancient chemical,” says Andrews. “It is regulating many different processes, and when you disturb these things, you can expect that it is going to cause some harm.”
Stafford Lightman, professor of medicine at the University of Bristol, and a leading UK expert in brain chemicals and hormones, says Andrews’ review highlights some important problems, yet it should also be taken with a pinch of salt. “This report is doing the opposite of what drug companies do,” he says. “Drug companies selectively present all the positives in their research, while this search selectively presents all the negatives that can be found. Nevertheless, Andrews' study is useful in that it is always worth pointing out that there is a downside to any medicine. ” Professor Lightman adds that there is still a great deal we don't know about SSRIs-not least what they actually do in our brains.
When it comes to understanding why the drugs work only for a limited part of patients, U.S.  scientists think they might now have the answer. They think that in many depressed patients, it’s not only the lack of feel-good serotonin causing their depression, but also a failure in the area of the brain that produces new cells throughout our lives. This area, the hippocampus, is also responsible for regulating mood and memory. Research suggests that in patients whose hippocampus has lost the ability to produce new cells, SSRIs do not bring any benefit.
小題1:According to paragraph 2, serotonin, like a chemical Swiss Army knife, can             .
A.make many patients' depression worse
B.cause a wide range of unwanted effects
C.a(chǎn)ffect human body and brain in various ways
D.provide little benefit for most depressed people
小題2:In Stafford Lightman's opinion,                    .
A.drug companies don't know the negative effect of antidepressants
B.Andrews focused on different things from the drug companies
C.scientists have found what SSRIs do in the brain
D.Andrews' research has no medical value
小題3:Which of the following is TRUE about SSRIs?
A.They are used to increase the “feel-good” medical in the brain.
B.They can work even when the hippocampus can't produce new cells.
C.They create a risk of heart problems in pregnant women.
D.They are responsible for controlling mood and memory.
小題4:What is the text mainly about?
A.The aim of drug companies

Beautiful cars surrounded by even more beautiful models—it’s no secret why the 2012 Beijing Auto Show was popular.
The exhibition was held between April 23 and May 2.Although renowned companies showed off their top models,it wasn’t just their expensive sports cars that grabbed people’s attention.
Concept cars are a way for designers to test out their ideas on the public with complete freedom.They can try out cars with special features that could not be massively(批量)produced easily.
Designers don’t have to follow industry rules;they don’t even need to worry about whether their cars would be followed on the roads.
At the Beijing Auto Show,the@Ant by Chery was one concept car to draw a lot of attention.China Daily called it‘‘the very definition of a concept car”.
The vehicle is powered by electricity and is capable of driving itself.But the magic doesn’t end there.
The@Ant was inspired by actual ants.According to Car News China,with the help of automated telemetric systems,@Ants are able to“see” other@Ants and compare  destination information. If two are heading the same way for a while, the vehicles connect, with one car’s rear (后面的)wheels matching up with the front wheels of another car.Up to 10@Ants can be put together and will automatically connect to form a“train".This  will help save energy while traveling, as well reducing traffic jams.
The car sounds like a great idea.Further research will be needed to turn this concept  car into something for the market,but concepts like Cherry’s  show how carmakers are  working for cleaner and greener vehicles.It’s like what the@Ant motto says,“Exploring future human beings’lifestyles”.
小題1:The concept car is getting popular because         .
A.it looks like an ant
B.it is beautifully designed
C.it is exhibited as a top model
D.it conveys a new idea for the future

The computer keyboard helped kill shorthand---a system of rapid handwriting, and now it's threatening to finish off handwriting as a whole. When handwritten essays were introduced on the SAT exams for the class of 2011, just 15% of the most 1.5 million students wrote their answers in cursive (草寫字母).The rest? Block letters.
And those college hopefuls are just the first edge of a wave of US students who no longer get much handwriting instructions in the primary grades, frequently 10 minutes a day or less. As a result, more and more students struggle to read and write cursive.
At Keene Mill Elementary School in Springfield, all their poems and stories are typed. Children in Fairfax County schools are taught keyboarding beginning in kindergarten. Older students who never mastered handwriting say it doesn't affect their grades.
There are those who say the culture is at a crossing, turning from the written word to the typed one. If handwriting becomes a lost form of communication, does it matter?
It was at University of Virginia that researchers recently discovered a previously unknown poem by Robert, written in his unique script. Handwritten documents are more valuable to researchers, historians say, because their authenticity (真實性)can be confirmed. Students also find them more fascinating.
The loss of handwriting also may be a cognitive (認知的)opportunity missed. Several academic studies have found that good handwriting skills at a young age can help children express their thoughts better-a lifelong benefit.
It doesn't take much to teach better handwriting skills. At some schools in Prince George's County, elementary school students use a program called Handwriting Without Tears for 15 minutes a day. They learn the correct formation of manuscript letters through second grade, and cursive letters in third grade.
There are always going to be some kids who struggle with handwriting because of their particular neurological (神經(jīng)系統(tǒng)的)wiring, learning issues or poor motor skills. Educators often point to this factor in support of keyboarding.
小題1:What is the author concerned about after 2011 SAT exams?
A.Keyboarding.B.Shorthand
C.Handwriting.D.Block letters.
小題2:A poem by Robert mentioned in the passage is used to _________.
A.prove how valuable handwriting is
B.explain what a famous poet he is
C.show how unique his poem is
D.stress how fascinating the documents are
小題3:The example of Handwriting Without Tears helps to argue that_________.
A.the schools are responsible for the loss of handwriting
B.the loss of handwriting is a cognitive opportunity missed
C.it doesn't take much to teach better handwriting skills
D.the culture is turning from the written word to the typed one
小題4: According to the author, when is a perfect time to learn handwriting?
A.Kindergarten.B.Primary school.C.High school.D.College.
小題5:What is the author’s attitude towards this debate?
A.Devotion.B.Encouragement.C.critical.D.Objective.

When you travel in South America, you’d better pay attention to the following three kinds of dangerous South American animals.
Piranhas(水虎魚)
Although only a small number of piranhas are considered to be dangerous to humans, the red-bellied piranha is definitely one of those. Evidence has shown that a large group of piranhas can absolutely eat a herd of large animals crossing the river, leaving only bones. This fish lives in the freshwater streams of South America, and they can smell the blood from far away and launch attacks swiftly. It is said that they are only dangerous to humans if the water volumes are less and lower.
Anacondas(水蟒)
This South American monster of a creature often appears in the films or your nightmares!They have weighed over 230 kilograms. It is often considered to be the biggest snake in the world. You certainly don’t want to get caught alone with this snake due to its method of attacking and killing its victim. It is indeed a remarkably different brand of snake type as it regularly coils(纏繞)around all over its target, increasing the pressure until eventually its victim dies. Its jaws are powered by large muscles that produce enough power for its over 100 sharp teeth to pass through the thick skin of an crocodile. They don’t have poison. Sometimes they prefer to camouflage themselves so they look like their surroundings and swiftly draw back when humans are near.
Golden Poisonous Frogs
The golden poison frog might be the most-deadly of the South American animal, which is protected by means of poison. This very small frog, less than 55 mm in length, packs enough punch(效力)to take down a pair of African bull elephants. This apparently harmless frog has always been known to have killed people who have touched it directly. It’s also been noted that chicken and dogs have died by contacting things on which a golden poison frog had wandered! In intense colors, they normally look attractive to their targets.
小題1:What can we learn about piranhas from the passage?
A.Piranhas are the most dangerous animals.
B.Piranhas like to live in the deep seabed.
C.Piranhas may attack human beings when the water level is low.
D.Piranhas only attack human beings when they cross the river in groups.
小題2:How does an anaconda kill its victim according to the passage?
A.It often uses its poison to kill its victim.
B.It often uses its strength to kill its victim.
C.It kills its victim mainly using its powerful teeth.
D.It kills its victim with the help of other snakes.
小題3:The underlined word “camouflage” in Paragraph 3 means “________”.
A.hide itself by appearing like the surroundings
B.terrify and capture the enemy by making much noise
C.move around to search for delicious food
D.give off harmful gas to kill the targets
小題4:Chicken and dogs are mentioned in Paragraph 4 to show that ________.
A.no animals can survive the poison of the golden poison frog
B.they like to wander along the path of the golden poison frog
C.the golden poison frog likes eating them most
D.the poison of the golden poison frog is deadly

It had been a difficult move. I’d left my family and friends in Indiana, the beloved state where I’d lived most of my life. My new home in Florida was thousands of miles away from anything I knew. It was hot—all the time. Jobs were hard to come by, but I was up for almost any challenge.
At last, I taught in a special school where students have severe learning and behavioral difficulties.
Another teacher and I had spent weeks teaching the children appropriate behavior for public outings. Unexpectedly, only a few students, including Kyle, had not earned the privilege of going. He was determined to make his disappointment known.
In the corridor(走廊) between classrooms, he began screaming, cursing, spitting, and swinging at anything within striking distance. Once his outburst died down, he did what he’d done when he was angry at all his other schools, at home, even once at a juvenile detention(拘留)center. He ran.
People watched in disbelief as Kyle dashed straight into the heavy morning traffic in front of the school.
I heard someone shout, “Call the police!”
But I ran after him.
Kyle was at least a foot taller than me. And he was fast. His older brothers were track stars at the nearby high school. But I could run long distances without tiring. I would at least be able to keep him in my sight and know he was alive.
After several blocks of running directly into oncoming traffic, Kyle slowed his pace.
He took a sharp left. Standing next to a trash bin, Kyle bent over with his hands on his knees. I must have looked ridiculous. But his was not a look of fear. I saw his body relax. He did not attempt to run again. Kyle stood still and watched me approach. I had no idea what I was going to say or do, but I kept walking closer.
He opened his mouth to speak when a police car pulled up, abruptly filling the space between Kyle and me. The school principal and an officer got out. They spoke calmly to Kyle, who willingly climbed into the back of the vehicle. I couldn’t hear what was said, but I didn’t take my eyes off Kyle’s face, even as they drove away.
I couldn’t help but feel that I had failed him, that I should have done or said more, that I should have fixed the situation.
I shared my feelings with a speech therapist who was familiar with Kyle’s history. “No one ever ran after him before, Rachel,” she said. “No one. They just let him go.”
Things changed the day he ran and I ran after him, even though I didn’t have the right words, even though I wasn’t able to save him from the mess he was in. It was the day I didn’t throw my hands in the air and decide he was too fast, a waste of time and effort , a lost cause. It was the day my mere presence was enough to make a profound difference.
小題1:From the passage we know that _____.
A.the author left her family to Florida because jobs were hard to come by in Indiana.
B.students were allowed to go out after they passed some specific tests.

The rat is named Lola and she’s at the top of her class of risk-running animals being trained to smell out landmines (地雷) in Colombia, home to the world’s highest number of mine-related deaths and injuries last year. Of the victims, many are children who died in the accidents while walking to school or playing in the countryside.
The smartest rat among the first six that the government is teaching to locate landmines equipment planted by rebels(叛亂者) has a 90 percent success rate in locating landmines material in her lab training.
Police animal trainers, tired of seeing their landmines-smelling dogs blown up by stepping on mines, hope the white-furred, pink-eyed creature will lead her classmates through coming open field tests and then into the country mine fields before the end of the year. It takes about 400 grams of pressure to detonate (引爆) a mine while Lola only weighs about 220 grams. “The dogs can easily set off the landmines, sometimes killing people nearby,” they said.
Police animal trainer Jose Pineda says that rats have more sensitive noses than dogs, which should allow them to better smell out mines in difficult terrain (地形).
Plus, it takes the police about six months to train mine-smelling dogs. Training the rats is expected to take about half that time once the program is established.
Trainers think that they are much smarter than the dogs. The second-best scorer in the laboratory is Lucrecia, with an 83 percent success rate. Males, such as one named   Runcho, have fallen behind until now but may do better in the coming field tests. Pineda said that the next step of training will present new challenges to the rats as they are sure to meet distractions (分心的事) in the open.
小題1:What do the underlined words “the accidents” in the first paragraph mean?
A.Children were shot while playing outside.
B.A buried landmine was walked on and set off.
C.A rebel blew up a landmine and killed children.
D.Children got hurt in traffic accidents on the way to school.
小題2:Which of the following is NOT a reason why rats are chosen to find buried landmines?
A.They have a good sense of smell.
B.They are too light to set off buried landmines.
C.They can smell all kinds of explosive materials.
D.They cost people less time in terms of training
小題3:What can we learn from the last paragraph?
A.Rats will perform as well in the open air as in the lab.
B.Until now, female rats are better than the male ones.
C.Trainers should have chosen only female rats for the program.
D.Because they are foolish, dogs are not preferred for the program.
小題4:What would be the best title for the passage?
A.Dogs Bring Peace to the People in Colombia
B.Colombia Develops a New Way to Reduce Deaths
C.Buried Landmines are a Great Danger to Colombians
D.Colombian Police Train Rats to Sniff Out Landmines
