Bats are the only mammals(哺乳動(dòng)物) which can fly properly. Other flying mammals have wings of thin skin which cover their sides between their front and back legs. They can only fly from tree to tree, but they cannot change direction when they want to.
All bats fly at night and most of them hunt for flying insects(昆蟲(chóng)), such as bees. The common bat finds its food by making a constant noise that the human ear cannot hear. The bat listens for echoes(回聲) of the noise as it bounces(反射) off the insects showing the bat their position.
The Fruit bat feeds on many different kinds of fruit. It does not use echoes but instead has very large, special eyes to see even in low light. The largest Fruit bat has a wing length of 0.75 meters. The Vampire bat drinks the blood of large mammals, and a few bats catch fish, birds and even other bats.
小題1: Some flying mammals are not real flyers because _____.
A．they do not have wingsB．their wings are too thin
C．they have skin between their legsD．they cannot turn around in the air
小題2: When common bats hunt for food they _____.
A．use echoes to kill the insectsB．make a noise to draw insects to them
C．produce a sound and listen to the echoesD．listen noise made by the insects
小題3: Unlike other bats, the Fruit bat _____.
A．can see very wellB．eats fruit and fish
C．has very long wingsD．has excellent hearings
小題4:The word "it" in the second paragraph refers to _____.
A．the batB．the echoC．the noiseD．the insect

Bexley Middle School eighth-graders won the grand prize at the 2009 National Engineers Week Future City Competition (TM) on Feb. 18 in Washington, D.C. They competed with 37 other schools across the country.
The students qualified for the national competition by winning a regional competition on Jan. 17 in Columbus. By winning the national event, the students earned an all-expenses paid trip to Space Camp in Huntsville, Ala., according to a Bexley school district news report.
Future City aims to stir (激發(fā)) interest in science, technology, engineering and math among young people. Bexley team members were Tom Krajnak, Abby Sharp, Wyatt Peery, Elizabeth Maher, Aaron Hutchinson and Truman Haycock. They work in teams under the guidance of a teacher, Margaret Englehardt, and a volunteer engineer, Mark Sherman, design and build a city of tomorrow. Mayor John Brennan presented the students during a recent Bexley City Council meeting. Each team in the Future City competition plans its city using Sim City software and creates a model to show a physical representation of one section of the city. Team members must write both an essay about the yearly theme and an abstract about their city. They also must make a presentation to judges.
Focusing on eco-responsibility, the Bexley team built “Novo-Mondum,” an Icelandic city in the year 2171. Krajnak said the team’s project included a new water system for each resident unit and a 500-word essay on using bacteria to purify water. “We used our essay and abstract (摘要) to build a model,” he said. “It was hard to organize which building would go where, what each building does and how to make it look good.”
Englehardt said her students did a good job answering impromptu (即席) questions during the regional competition. “They can think on their feet,” she said. Principal Harley Williams said the school is very proud of the students’ performance.
小題1:.. From the passage we can learn that the grand prize winners will _________.
A．receive scholarship for further studies

Scientists have found what look like caves on Mars, and say they could be protecting life from the planet’s terrible environment.
The first caves appear as seven mysterious black dots （點(diǎn)） on the pictures which were sent back by NASA’s Mars Odyssey orbiter. Each as large as a football field, they may be openings into natural caves below the Martian surface.
“If there is life on Mars, there is a good chance that you’d find it in caves,” said Jut Wynne, one of the researchers who noticed the features (特征) while working on a US Geological Survey Mars Cave Detection Program.
Jonathan Clarke, a geologist with the Mars Society of Australia, yesterday described the discovery as exciting.
One photo taken at night by an infrared imager(紅外線成像器) showed one hole to be unusually warm, suggesting hot air may be flowing out.
“I said: ‘Wow, that’s a cave’” Dr. Clarke said excitedly. “People have been looking for these for a long time; now we have found them.”
He agreed such caves could be perfect places to search for life escaping from the bitterly cold, radiation-soaked(充滿輻射的), dry surface.
“Tiny drops of water could collect inside,” he said. “If there are gases coming out, they could provide energy for a whole range of bacteria (細(xì)菌). A cave is also a protection from radiation; the surface of Mars is exposed to high levels of space radiation.”
The caves probably formed when tube-shaped lava flows(管狀巖漿流) spread across the planet long ago. The outside of the tubes cooled, forming solid walls, while something hotter inside allowed the remaining to flow out, forming caves.
小題1: What does the passage mainly talk about?
A．How the caves were formed on Mars.
B．How NASA sent the pictures back to earth
C．Caves on Mars may be full of hot air or a sign（跡象）of life.
D．Scientists have completely recognized the surface of Mars.
小題2: We can learn from the passage that __________.
A．water has already been found on Mars
B．the scientists found all the caves at night
C．it is certain that there is life in these caves
D．the surface of Mars is bitterly cold, radiation-soaked and dry
小題3: According to the passage, Dr. Clarke was so excited because ________.
A．such caves could provide energy for life
B．they had finally found the caves on Mars
C．such caves would be perfect places to search for life
D．There would be life on Mars.
小題4: Necessary conditions for life on Mars mentioned in the passage may include_________.
A．lava and energyB．water and radiation from space
C．gases and lavaD．water and protection from radiation
小題5: what does the underlined word “ the planet” in paragraph 1 refer to?
A．the MarsB．the earthC．the cavesD．radiation

Every pet owner loves his pet .There is no argument here.
But when we asked our readers whether they would clone their beloved animals , the responses were split(分裂) almost down the middle . Of the 228 readers who answered it ,108 would clone, 111 would not and nine weighed each side without offering an opinion .
Clearly, from readers’ response, this is an issue that reaches deeply into both the joy and eventual (最終的)sadness of owning a pet. It speaks, as well, to people’s widely differing expectations over the developing scientific procedure (步驟)
Most of the readers who favored the idea strongly believed it would produce at least a close copy of the original; many felt the process would actually return an exact copy. Those on the other side, however, held little hope that clone could truly recreate a pet; many simply did not wish to go against the natural law of life and death.
Both sides expressed equal love for their animals. More of them owned “the best dog/cat in the world”. They thought of their pets as their “best friend” or “a member of the family”. They told moving stories of pets’ heroism, intelligence and selfless devotion.
No wonder the loss is so disturbing---and the cloning so attractive. “People become very close to their animals, and the loss can be just as hard to bear as when a friend or family member dies,” says Gary Kowalski, author of goodbye, Friend: Healing Wisdom for Anyone Who Has Ever Lost a Pet. “For me, cloning feels like an attempt to turn death away…It’s understandable. Death is always painful. It’s difficult to deal with. It’s hard to accept.”
But would cloning reduce the blow? This question seems to be at the heart of this problem.
小題1:
As far as the cloning of pets is concerned, a recent survey shows that, of all pet owners,     .
A．a(chǎn) lot more of them are for itB．a(chǎn) lot more of them are against it
C．very few of them are willing to tell their opinions
．		D．a(chǎn)bout half of them are for it and the other half against it
小題2:
The expression “eventual sadness of owning a pet.” (in paragraph 3) refers to       .
A．the death of one’s pet
B．the final ownership of a pet
C．the troubles one has to deal with in keeping a pet
D．the dangers involved in the cloning of a pet
小題3:
In spite of their differences on the problem of cloning, it seems that     .
A．a(chǎn)ll pet owners love their pets very much
B．a(chǎn)ll pet owners try to go against the natural law of life and death
C．people who support cloning love their pets more
D．people who dislike cloning love their pets more
小題4:
From what Gary Kowalski says, we can know that he     .
A．has never thought about the problem of cloning
B．thinks it hard to accept the idea of cloning pets
C．is in favor of the idea of cloning pets
D．is all against the cloning of pets

ERATH WEEK---A DIARY OF THE PLANET
Enduring Storms
Several more rounds of severe storms, tornadoes and flash flooding struck many parts of the American Midwest and Northeast as bad weather continued across the US for a second month.   

Monsoon Storms
A south-west monsoon has caused havoc in parts of Sri Lanka. Government meteorologists said that unexpected monsoonal winds blew directly across the country from the Southern Hemisphere at about 100km/h, producing several rounds of stormy weather. Nearly 250 houses in the capital Colombo were damaged.
Mt. Etna Erupts
Sicily’s Mount Etna volcano erupted shortly after midnight on July 1, shooting “bombs” of lava nearly 1.5 meters in diameter on the eastern side of the mountain. The 30-minute eruption could be seen for several miles, but did not threaten any nearby villages.
Hurricane
Hurricane Blas lost strength as it moved over cooler waters in the Pacific Ocean to the west of Mexico. Blas formed off southwest Mexico during the previous week, but squalls on the outer fringes of the storm lashed western Michoacan State, killing four people when their wood and cardboard home collapsed.
Monkey Repellent
After years of unsuccessful attempts to keep crop-eating monkeys out of Japanese fields, a Tokyo research team believes that it may have finally found a way to prevent the damage caused by the monkeys. Animal raids on crops were successfully prevented by shooting chilli powder into the air, irritating the eyes and noses of monkeys that passed in front of carefully-placed warning sensors. “We’ve tried al kinds of preventive measures, but the monkeys are smart enough to outwit the tricks, “said Toshiaki Wada, Director of the Tokyo Forestry Experiment Station in western Tokyo.
小題1:.
. According to the information, which of the following statements is TURE?
A. The eruption of Mt. Etna lasted thirty days.
B. Hurricane Blas was formed off the coast of Italy.
C. The American Midwest had fine weather throughout July 1998.
The eruption of Mt. Etna did not destroy local villages.

Many schools have established successful home visit programs. Home visits by teachers let parents and children know how much teachers care. Also, it is a way for teachers to learn more about their students , get the parents to pay more attention to their children’s education and bridge cultural gaps that might exist between students and teachers. Most teachers report that their home visits have a lasting effect on the child, the parents and on parent—teacher communication.
The Head Start program has used home visits for many years. Head Start teachers are required to make at least two home visits for each student, regardless of their ability, during each school year in addition to regular parent-teacher conferences at school. Many U.S. kindergartens also require home visits by teachers before school starts.
The visit approach varies from school to school and usually depends on the funding the source. In some schools, teachers prefer to visit in pairs. They feel more comfortable that way and sometimes need a translator in order to communicate with a child’s parents. Other teachers visit one-on-one with parents. Some interact with both the child and the parent. Many teachers may bring along learning activities for the child that also involve the parents participation. Normally, visits can last from 30 to 90 minutes, depending on the teacher and the activities.
When teachers get to know their students and their students’ families, the parents become more active in their children’s education. Home visits, not unnecessary as some people think, can give teachers the ideas they need to help all students succeed.
小題1: Home visits by teachers can         
A．bridge cultural gaps existing between parents and teachers.
B．get students know that their teachers care about their parents.
C．get parents involved in their children’s education.
D．help establish good relationships between parents and children.
小題2:From the second paragraph we know that home visits       
A．a(chǎn)re not a new idea
B．a(chǎn)re traditionally done by teachers before school starts
C．a(chǎn)re meant for students with low marks
D．have replaced parent-teacher meeting
小題3:What is the third paragraph about?
A．Reasons for home visists
B．Forms of home visits
C．Advantages of home visits
D．Tips for home visits
小題4: What is the effect of home visits?
A．Parents have more opportunities to play with children
B．Students can succeed more easily through their own efforts.
C．Parents play a decisive role in children’s education.
D．Teachers can learn more about how to help students.

For several years, scientists have been testing a substance called interferon(干擾素), a possible wonder drug that is proving to be effective in treating a variety of diseases, including virus infections, bacterial infections, and cancers. To date, the new drug has no side effect of great influence to discourage its use.  But in spite of its success, last year only one gram was produced in the entire world.
The reason for the shortage lies in the structure of interferon. A special protein, the interferon produced from one animal species cannot be used in treating another animal species. In other words, to treat human beings, only interferon produced by human beings may be used. The drug is produced by infecting white blood cells with a virus. Fortunately, it is so effective that the amount given to each patient each time is very small.
Unlike antibiotics (抗生素), interferon does not attack germs directly. Instead, it protects healthy cells from being infected, and prevents the reproduction of viruses within cells.
As you might conclude, one of the most special uses of interferon has been in the treatment of cancer. Dr. Hans Strander, a research physician at Sweden’s famous Karolinska Institute, has treated more than one hundred cancer patients with the new drug. Among a group of selected patients who had received operations for advanced cancer, half were given  traditional treatments and the other half were given interferon. Among those treated with interferon 70 percent of them remained alive over three years, as compared with only 10 to 30 percent among those who had received the traditional treatments.
In the United States, a large-scale project supported by the American Cancer Society is now under way. If the experiment were successful, interferon could become one of the greatest medical discoveries of our time.
小題1:What is the difference between antibiotics and interferon?
A．Interferon has serious side effects, while antibiotics do not.
B．Antibiotics kill germs by attacking them directly, while interferon does not.
C．Antibiotics are very effective, while the effect of interferon is limited.
D．They are different in structure, although they are both proteins.
小題2:According to the passage, if 170 cancer patients received interferon treatment, how many of them would remain alive over three years?
A．About 30.
B．About 50.
C．About 120.
D．About 70.
小題3:The passage tells us that ________.
A．it is difficult to produce interferon in large quantities because of its special structure.
B．interferon is produced widely in lots of countries.
C．few of the patients who had received traditional treatments remained alive.
D．most of the patients who received interferon also needed traditional treatments.

The German shepherd runs off and noses around in the grass of Kenya’s Laikipia Plateau. “OK, Oakley,” the dog’s handler orders, “Find it!”
Oakley sniffs (嗅) until he comes to a bush, then stops, sits, and looks up at his handler. She bends to see what he has found: the waste of an endangered African wild dog. “Good dog!” she praises. The handler pulls a tennis ball from her pocket. Oakley jumps for his reward.
“He doesn’t actually want the waste,” says Aimee Hurt, a founding member of the U.S.-based group Working Dogs for Conservation. Hurt is in Kenya to train both Oakley and his handler. “He finds it so he can play with his ball. We’re the ones who want the waste.”
Detection dogs are sometimes taught to locate actual animals. Black-footed ferrets (雪貂) have been studied with their help. But more often the dogs learn to locate the waste of creatures such as bears, wolves and mountain lions.
What the dogs find provides scientists with data about a species. Scientists can use the DNA collected from animal waste to identify individuals, sex, and population sizes — all without ever seeing the animal itself. “It can take years to gather this kind of information if you have to trap animals,” Hurt explains.
Waste analysis might make a huge difference when wild species are accused of attacking domestic livestock (家畜). Hurt says, “A good detection dog will find the waste so we can see what the animal is actually eating.” This may help reduce problems between people and wildlife.
小題1: The underlined word “She” in Paragraph 2 refers to  “_____”.
A．the German shepherd
B．a(chǎn)n African wild dog
C．Aimee Hurt
D．the handler
小題2: Oakley is interested in finding the waste because _____.
A．he wants to study endangered animals
B．he can get a tennis ball to play with
C．he wants to eat it
D．he wants to play with it
小題3:Which of the following is TRUE according to the passage?
A．Trapping animals is not difficult.
B．People are making efforts to protect the environment.
C．Detection dogs attack domestic livestock frequently.
D．Collecting animal waste is a good way to gather information.
小題4:What is the main idea of the passage?
A．Detection dogs can help scientists study wildlife.
B．Detection dogs can defend wildlife.
C．Detection dogs can help the police catch the criminals.
D．Detection dogs can help local people defend domestic livestock.
