Robots are smart. With their computer brains, they help people work in dangerous places or do difficult jobs. Some robots do regular jobs. Bobby, the robot mail carrier, brings mail to a large office building in Washington, D.C. He is one of 250 robot mail carriers in the United States. Mr. Leachim, who weights two hundred pounds and is six feet tall, has some advantages as a teacher. One is that he does not forget details. He knows each child’s name, their parents’ names, and what each child knows and needs to know. In addition, he knows each child’s pets and hobbies. Mr. Leachim does not make mistakes. Each child goes and tells him his or her name, then dials an identification (識(shí)別) number. His computer brain puts the child’s voice and number together. He identifies the child with no mistakes.
Another advantage is that Mr. Leachim is flexible. If the children need more time to do their lessons they can move switches. In this way they can repeat Mr. Leachim’s lesson over and over again. When the children do a good job, he tells them something interesting about their hobbies. At the end of the lesson the children switch Mr. Leachim off.
小題1:The first paragraph of the passage tells us
A.human beings are not as smart as robots
B.robots will take the place of man to rule the earth
C.we can only use robots to do some regular jobs
D.robots can help people in many different ways
小題2:What is the most important thing Mr. Leachim can do in his lessons?
A.To meet the needs of each student.
B.To talk to the students in different languages.
C.To keep everyone’s interest in his lessons.
D.To introduce more hobbies to the children.
小題3:The underlined word “flexible” probably means
A.not strictB.not hard
C.suitableD.changeable
小題4:Which of the following statements may be TRUE according to the passage?
A. There are 250 robot teachers in the United States.
B. Mr. Leachim is run and controlled by electricity.
C. Bobby works in a large office building in Washington D.C.
D. The lessons taught by Mr. Leachim are given on a TV set.

小題1:D

試題分析:本文介紹了智能機(jī)器人的多種用途。Bobby可以從事人們正常的工作,可以送郵件等等,像這樣的機(jī)器人美國有250個(gè)。而機(jī)器人Mr Leachim是有著許多優(yōu)勢(shì)的老師,他可以去滿足不同孩子的不同需求,而且使用方便。
小題1:D主旨大意題。文章開頭提出Robots are smart. With their computer brains, they help people work in dangerous places or do difficult jobs.然后舉了兩個(gè)機(jī)器人的例子,由此可知文章中心是介紹機(jī)器人在多方面對(duì)人類的幫助,所以D選項(xiàng)正確。
小題2:A細(xì)節(jié)理解題。文章第一段介紹了機(jī)器人老師Mr Leachim的很多優(yōu)勢(shì),從what each child knows and needs to know. In addition, he knows each child’s pets and hobbies.可以推斷A選項(xiàng)正確。
小題3:D詞意猜測(cè)題。從文章最后一段的介紹可知孩子們可以隨時(shí)聽老師的講課,也可以一遍遍播放老師的講課內(nèi)容,由此推斷flexible意思是“靈活的”,所以D選項(xiàng)正確。
小題4:B推理判斷題。從文章最后一段If the children need more time to do their lessons they can move switches. 和At the end of the lesson the children switch Mr. Leachim off. 可以判斷機(jī)器人老師是由電操作控制的,故B選項(xiàng)正確。

A warm blanket is the ideal sleep aid for a freezing winter night. The right blanket can warm your bones but the wrong one can affect your sleep. I asked experts for advice on picking the perfect blanket for a good night’s sleep. Here’s what they told me.
When it comes to sleep temperature, experts recommend following the principle: not too cold, not too hot, but just right. “People seem to sleep best at temperature between 62 and 70 degrees F,” says Dr. Alice Hoagland. When the surrounding temperature falls too low, it can rouse you from sleep. A good blanket helps drive the coldness away.
At the other extreme, overheating yourself can affect your sleep as well. “Core body temperature typically drops during the first four hour’s of sleep,” says Dr. Hoagland. This decline in body temperature helps you fall asleep and stay asleep.
“In medical care, weighted blankets are one of our most powerful tools for helping people who are anxious, upset, and possibly losing control,” says Dr. Karen Moore. These special blankets are filled with weighted pellets. Weighted blankets are also marketed for general use as an aid to sleep and relaxation. Like a firm hug, weighted blankets help us feel safe.” This is the reason why many people like to sleep under a blanket even in summer.
“If you want to try this type of blanket, the best weight depends on your body size and personal preference. However, 15 to 30 pounds is typical for adults,” Moor says. She adds that weighted blankets are not recommended for those recovering from surgery.
“People can also have serious preferences for a particular blanket,” says Dr. Hoagland. “Regularly using a favorite blanket for sleep can help to develop a conditioned response so that sleep is quicker.” In fact, many sleep centers ask patients to bring their own blanket and pillow from home, which helps them fall asleep more easily.
小題1:The author wrote the passage mainly to tell us _____.
A.the importance of blankets
B.how to choose the perfect blanket
C.different materials used to make blankets
D.the history and usage of blankets
小題2:The underlined word “rouse” in Paragraph 2 is the closest in meaning to “______”.
A.wake upB.take upC.make upD.pick up
小題3:What do we know from the passage?
A.Body temperature rises when we fall asleep
B.The perfect sleep temperature should be above 70 degrees F.
C.Weighted blankets should be at least 30 pounds.
D.People are advised to use their own blankets.

Watercress is positively packed with healthy vitamins and minerals. The writings of both the Romans and the Ancient Greeks record the consumption of watercress by all classes. Hippocrates, “the father of medicine”, was so convinced that watercress was a great healer that he built his first hospital next to a stream so that he could grow a plentiful supply of the shiny green leaves for his patients. The Romans chewed watercress in large quantities, believing that it would cure baldness. They, too, looked with favor on watercress as a salad.
Watercress sandwiches were traditionally a breakfast item in nineteenth-century Europe. The most basic type of watercress sandwich has two pieces of white bread with a mixture of butter and watercress greens . A nickname(綽號(hào))for the vegetable, in fact, was “poor man’s bread”, because watercress was often eaten on its own for breakfast by families that could not afford the bread to go with it.
Watercress is a member of the mustard(芥菜) family. It contains vitamins C(66mg per 100g), K and A, and is also a valuable source of minerals such as iron, potassium, copper and calcium. The mustard oils in its silky leaves and stems(莖)contain an ingredient known as PEITC. Recent research has proved that PEITC can prevent the growth of cancer cells and, in some cases, actually destroy them.
The best watercress has silky green leaves without any marks and has undamaged stems, The older the plant, the darker are its leaves and the thicker its stems. This means a higher concentration of oils and vitamins. Young watercress, on the other hand, may be harvested after only twenty-eight days growth and has a milder taste. It is  best to eat watercress fresh and raw , to keep more of its valuable nutrients, but it can be lightly cooked and used as an alternative to spinach—another dark green vegetable—in various recipes. From soups to salads, watercress is now considered around the world as a natural and healthy super food.
小題1:From paragraph 1, we can learn that________.
A.watercress is usually grown in wet areas
B.the ancient Greeks only used watercress for medicine
C.watercress is the most ancient vegetable known to man
D.the Romans rubbed watercress on their heads to cure baldness
小題2:The underlined word “it” in paragraph 2 refers to “_________”.
A.butterB.watercressC.breakfastD.bread
小題3:Which of the following is TRUE about watercress?
A.It belongs to the same family as spinach.
B.It contains mustard oils only in leaves.
C.It can help guard against cancer.
D.It is rich in vitamins C and B.
小題4:Compared with older watercress, young watercress      .
A.has lighter green leaves
B.contains more minerals
C.is better for medical use
D.is more suitable for eating raw
小題5:What would be the best title for the text?
A.The history of watercressB.watrcress, a medicinal plant
C.Watercress, the amazing foodD.New findings about watercress

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(qiáng)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
小題1:The author wrote this letter in order to ______.

If your idea of a good time is to sleep in a hut, carry your own rubbish, and eat insects and wild animals, then ecotourism may be just for you. But is it also for people who want to fly over a rainforest sky before checking into a comfortable and expensive hotel in the middle of a national park? Whatever ecotourism is, it is hot--perhaps too hot for its own good.
The World Tourism Organization claims that the industry looked after 592 million travelers last year who spent $423 billion, and of all the types of tourism, ecotourism seems to be the fastest growing. By the broadest measure -- a trip with some sort of nature or wilderness element -- ecotourism already accounts for perhaps a third of these travelers. On a stricter definition favored by the Ecotourism Society, it is “responsible travel that preserves natural environments and keeps up the well-being of local people,” which accounts for no more than 5% of tourism.
Ideally, ecotourism helps both people and nature. Before the disastrous civil war, Rwanda’s Mountain Gorilla Project was one such model. Visits to the gorillas were limited, local guides ensured good behavior or on the part of the humans, and the high admission charge - $170 a day -- paid for salaries and presentation of the gorillas’ living areas. As this made the gorillas worth more alive than dead, poaching (偷獵) decreased. As another example, preservation Cooperation, Africa’s largest ecotour operator, uses only local labor, buys products 5om local farmers, and supports building projects: such as clinics and schools. This contribution to social advance is also good business sense. Projects from which local people benefit directly are less likely to be affected by poaching and theft.
Ecotourism’s biggest problem is labeling. Going on an eco-tour is no guarantee of good ecology. So far, only Australia has an official system to grade tour operators and tourist attractions on the basis of their “greenness”. Another issue is how eco-tourists damage the environment. Dolphin-feeding, for instance, is innocent and enjoyable, but after too many free meals, the dolphins forget how to catch their own dinners.
Keeping prices high is one way to limit enthusiasm. But measuring the effect of ecotourism on human environments is trickier. It is common, for villagers to see ecotourism as a source of new income. Hence, the very tourists who venture in search of traditional cultures end up breaking them up. As ecotourism becomes more popular, it will finally threaten the very things that are good for business.
小題1:According to the passage, ecotourism may _________.
A.harm its own purpose by becoming too popular
B.save the environment by becoming more popular
C.harm its own purpose by becoming less popular
D.save the environment by becoming less popular
小題2:Within the tourism industry as a whole, ecotourism _____________.
A.has no single, clear definition that would satisfy everybody
B.has expanded less rapidly than other types of tourism
C.claims that no comfortable hotels should be used by tourists
D.most often has a negative effect on local culture
小題3:Rwanda’s Mountain Gorilla Project is a good example because ___________.
A.tourists were free to visit the gorillas whenever they wanted to
B.local people’s attitudes toward animals were not affected
C.the gorillas were protected from both tourists and local people
D.the gorillas’ living area was modernized because of the high admission
小題4: _________ most directly benefits the local community.
A.Rwanda’s Mountain Gorilla ProjectB.Preservation Corporation
C.Australia’s grading systemD.Dolphin-feeding

Australian scientists are trying to give kangaroo-style stomachs to cattle and sheep in order to cut he greenhouse gases they send out, which are thought to be responsible for global warming.
Thanks to special bacteria in their stomachs, kangaroo flatulence(腸胃氣脹)contains no methane(甲烷)and scientists want to transfer that bacteria to cattle and sheep who produce large quantities of the harmful gas.
While the usual image of greenhouse gas pollution is a billowing smokestack (煙囪) pushing out carbon dioxide, farm animals’ passing wind contribute a sur­prisingly high percentage of total emissions (排放物)in some countries.
“Fourteen percent of emissions from all sources in Australia are from enteric methane from cattle and sheep,” said Athol Kleve, a senior research scientist with the Queensland state government.
“And if you look at another country such as New Zealand, which has got a much higher agricultural base, they're actually up around 50 percent, ” he said.
Researchers say the bacteria also make the diges­tive process much more efficient and could potentially save millions of dollars in feed costs for farmers.
But it will take researchers at least three years to isolate (分離) the bacteria, before they can even start to develop a way of transferring it to cattle and sheep.
Another group of scientists, meanwhile, has suggested Australians should farm fewer cattle and sheep and just eat more kangaroos.
The idea is controversial (有爭(zhēng)議的), but about 20 percent of health-conscious Australians are believed to eat the national symbol already.
“It's low in fat, it’s got high protein levels and it's very clean in the sense that basically it's the free-range (放養(yǎng)的) animal,” said Peter Amp of the University of New South Wales's institute of environmental studies.
小題1:Scientists intend to put bacteria into cattle and sheep _________.
A.so that they can make full use of special bacteria
B.to help Australian farmers to earn more money
C.so that they can protect Australian ecosystem
D.to prevent them from sending out harmful gases
小題2:Athol Kleve seems to believe that ________.
A.cattle and sheep produce more carbon dioxide
B.less cattle and sheep are raised in New Zealand
C.farm animals are responsible for greenhouse gases
D.New Zealand has the most animals in the world
小題3:What do the underlined words “the idea” in para­graph 9 refer to?
A.Australians should farm fewer cattle and sheep and just eat more kangaroos.
B.The bacteria could make the digestive process much more efficient.
C.Australians should give kangaroo - style stomachs to cattle and sheep.
D.The bacteria could save millions of dollars in feed costs for farmers.
小題4:Which of the statements is the advantage Peter Amp lists about kangaroo?
A.it is rich in protein B.it is cheaper than beef
C.it is high in fatD.it is more delicious than sheep

Scientists Alan M.Goldberg and Thomas Hartung describe recent advances in replacing the use of animals in toxicology(毒物學(xué))testing.Improvements in cell and tissue culture technologies,for example,allow a growing number of tests to be performed on human cells alone.Computer models are becoming increasingly complex and many could one day become more accurate than trials in living animals.
Since the late 1990s,Huntingdon Life Sciences--a company that conducts testing of substances on animals conducted by the Environmental Protection Agency and the Food and Drug Administration—has become a proving ground for aggressive strategies by animal-rights militants (好戰(zhàn)分子).At a hearing,a Senate.committee listened to testimony(證詞) against Huntingdon employees and financial institutions providing services to the company.One experimentation witness at the hearing insisted that any means necessary were justified(辯護(hù)) to spare animals’ lives;he has previously accepted the idea of murder to that end.
Use of animals in testing and in biomedical research continues to be necessary in many instances and is ethically(倫理道德地)preferable to experimenting on humans or giving up cures that could save human lives.But for the sake of people and animals alike,the development and acceptance of animal substitutes deserve enthusiastic support.
In some instances, substitutes are already thought as good or better than animals,but supervising agencies(監(jiān)督機(jī)構(gòu))have yet to catch up.In both the European Union and the U.S.,scientists and companies wanting to use the new alternative tests complain that regulatory standards for proving a drug or chemical to be safe for humans force the continued use of animals.Thus,animal-loving Americans might turn to persuading the EPA and the FDA to speed validation(確認(rèn))of new methods so that they can be more widely employed.And animal advocates(保護(hù)者) who want to influence business could consider investing in the small biotech’s and large pharmaceutical(藥品的) companies that are working to develop alternatives to animals in research.
小題1:_____ plays a leading role in replacing the use of animals in testing.
A.Huntingdon Life SciencesB.Improvement in technologies
C.Animal-fights militantsD.Scientists Alan and Thomas
小題2:Accordingly, the animal-rights militants hold the view that_____.
A.a(chǎn)nimals shouldn’t be used in toxicology testing
B.a(chǎn)nimals should enjoy equal rights with human beings
C.a(chǎn)nimals should live wildly and freely
D.we should protect animals from being killed casually
小題3:From the passage,we can find _____.
A.the use of animals in testing has been stopped abruptly
B.a(chǎn)nimal substitutes are not preferable
C.supervising standards contribute to the continued use of animals in testing
D.only Huntingdon Life Sciences is accused
小題4:What’s the main idea of the passage?
A.Saving animals and people.
B.The new trend in toxicology testing
C.The use of animals in testing is against human nature
D.New technology changes the fate of animals
小題5:The writer’s attitude towards replacing the use of animals in toxicology is____.
A.a(chǎn)rbitrary(武斷的,隨意的)B.pessimistic
C.indifferent(不關(guān)心的 )D.optimistic

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(xué)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

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
