Empathy(同情心) lets us feel another person’s pain and drives us to help. Do any other animals feel empathy? Scientists recently found that rats(老鼠) do, too.
Most people don’t like rats. In many people’s eyes, rats are only bad. But Jean Decety and his partners at the University of Chicago did an experiment. It showed that rats are kind, warm-hearted animals. They can feel each other’s pain.
Scientists placed pairs of rats in plastic cages(籠子) for two weeks. During this time they got to know each other. Then they put one of the rats from each pair into a small container(容器) in the cages. The small container had a door. It was so designed as to fall to the side when the free rat touched it. Many of the trapped(困住的) rats squeaked(吱吱叫) to show their discomfort. The other rats of the pairs could see their suffering(受苦的) friends clearly.
In most pairs, the free rats would become very worried about their friends. They kept trying to save their friends again and again throughout the month. Scientists put the rats’ favorite chocolate in the cages, but the rats didn’t eat it until they had saved their friends successfully. Scientists also found that female rats seemed to act more empathetic than male rats.
“The results are the first to show that rats take action in response to another’s trouble,” Decety said. “Monkeys and chimpanzees have similar behavior. But unlike those animals, rats can be ready used in laboratory studies. They will help us to learn which parts of the brain lead to empathy and helping behavior and whether empathy is natural.”
小題1:A person with empathy is often _____.
A．kind-heartedB．cleverC．a(chǎn)ctiveD．strong
小題2:Why didn’t the free rats eat the chocolate at first?
A．Because they were not hungry at that time.
B．Because chocolate was not their favorite food.
C．Because they wanted to save the trapped rats first.
D．Because they were afraid that the chocolate was bad.
小題3:Which of the following animals were NOT mentioned in the passage?
A．Monkeys.B．Chimpanzees.C．Rats.D．Cats.
小題4:What does the passage mainly tell us?
A．Rats can feel other animals’ pain.
B．Chocolate is rats’ favorite food.
C．Rats are empathetic and can feel each other’s pain.
D．Female rats are more empathetic than male rats.

小題1:A
小題2:C
小題3:D
小題4:C

Scientists are developing a new kind of machine to take the place of humans. These machines can do jobs in places that are too dangerous for humans. For example, they are being developed to work in nuclear power center, deep under the oceans and in outer space.
John Marrit, a psychologist(心理學(xué)家) in Williamsburg Massachusetts, helped develop the new machine. This is how they work. A machine is placed in an area far away from the person who operates it. The person wears special hard hat with television screens and sound equipment. The screens and sound equipment let the person see and hear exactly what the machine is seeing and hearing. Mr. Marrit says this gives the person the feeling of being in the same place as the machine. The idea, he says, is being there without going there. The person uses an electronic control to make the machine move. The machine copies the person’s movements exactly. If the person raises his right arm, the machine raises the right arm, too. This means an expert can do a dangerous job while staying in the safe place. For example, a person can direct the machine to destroy a bomb without going near the bomb himself.
小題1:The new kind of machine being introduced in the passage is _______.
A．in existenceB．only an idea
C．being tried outD．being researched and developed
小題2:The machine _______.
A．follows the person’s order
B．is controlled by a computer
C．does exactly what the person does
D．is controlled by a television on the person’s head
小題3:The difference between such a new machine and a robot is that _______.
A．the new machine is more difficult to make than a robot
B．the new machine is more difficult to be controlled
C．a(chǎn) robot is controlled by man indirectly

Now campuses(校園) around the country have started recruiting（吸收某人為新成員） fresh faces for all kinds of clubs．Upperclassmen and experts suggest a hobby-based choice of clubs, which might have a lasting impact（影響）on one' s life and career Zhang Ling did not get many chances to write stories as an environmental protection major at Jiangxi University of Science and Technology．But this changed when she joined the university broadcast station．Her daily interviews with students and teachers expanded her horizon．Now she is determined to become a journalist on environmental issues with her degree in environmental protection．"Journalism changed my life track," said the 22 –year-old girl．"I only wanted to be a science teacher in a local senior high school．But now I am applying for a graduate school in journalism."
Lan Yujie, professor at Anhui University of Technology, regards Mu and Zhang as good examples of choosing "what I like" instead of " what is practical" in finding jobs and seeking further study． "Some freshmen don't know what to choose," said Lan．"Just following a hobby and doing something you like can easily give you the experience that makes you happy and special．"
Lan further says that joining clubs should not necessarily have a purpose,  As part of campus life, a club experience will impact one's life and career m one way or another．"The point of clubs is to have as many diverse（多樣的）experiences as possible so that students can explore more of their life," said Lan．

Conservationists have unveiled plans to preserve and protect the world's most important species of coral, in a response to increasing threats that they say will lead to "functional extinction" within decades．
Led by scientists at the Zoological Society of London, the Edge Coral Reefs project has identified 10 coral species in most urgent risk of becoming extinct．The scientists say that reefs are under pressure from a variety of threats including rising sea temperatures due to climatic instability, increased acidity（酸性）, overfishing and pollution．
The Edge plan, which focuses on the most evolutionarily distinct and globally endangered species , will take a regional approach to conservation．This means focusing on the "coral triangle" around the Philippines, the West Indian Ocean around the Mozambique channel, and in the Caribbean channel．
"Coral reefs are threatened with functional extinction in the next 20-50 years, due predominantly to global climatic instability," said Catherine Head, coordinator of the reefs project．"In these regions, we'll be supporting and training in-country conservationists to carry out research and implement targeted conservation actions," she said．"Their projects will last initially for two years．We provide them with a whole host of tools to carry out their projects including funding and intensive training．" She added．
Coral reefs are the planet's most diverse marine ecosystem（生態(tài)系統(tǒng)）, known as the rainforests of the oceans．Despite taking up under 0．2% of the ocean floor, they provide food and shelter for almost a third of all sea life．If we lose the ecosystems, we lose not only the biodiversity （生物多樣性）, but we also lose the capability of people to obtain income and food from coral reefs．
Climatic instability, which leads to rising sea temperatures, causes corals to bleach．Bleaching occurs when sea temperatures rise and this causes the coral tissue to expel their symbiotic algae called zooxanthellae - these are what give the coral their colour．Bleached corals often die if the stress continues．Among the 10 species chosen to start the Edge project are the pearl bubble coral, a food source for the hawksbill（玳瑁）turtle, and the Mushroom coral, which supports at least 15 brightly colored fish．
小題1:What does the first paragraph mean in the passage ?
A．Conservationists planned to preserve and protect some extinct corals years ago．
B．Conservationists have banned plans to protect endangered corals for years．
C．Conservationists are going to protect corals that are dying out in several ten years．
D．Conservationists have made plans to protect corals from being extinct in ten years．
小題2:What will probably happen to coral species with the increasing threats?
A．Decrease．B．Losing functions
C．Disappearance．D．Existence
小題3:Which of the following statements about the Edge Plan is TRUE?
A．The Edge Coral Reefs project was carried out by American scientists．
B．The plan concentrates on the channels to protect the endangered species．
C．The Conservationists have carried out the Edge plan for many years to protect the corals．
D．Ten coral species chosen by the project are at the greatest risk of becoming extinct．
小題4:Which of the following will be the consequence of coral extinction in the passage?
A．We will keep the balance of the marine ecosystems．
B．About one third of the marine species can't survive．
C．Man can benefit more from corals．
D．We will lose the rainforests on our earth．
小題5:What is the best title of the passage?
A．Climatic Instability and Coral Extinction
B．Reasons for Coral Functional Extinction．
C．A Plan to Save Coral from Extinction
D．A Research about Endangered Coral Reefs．

For centuries, magicians have used various ways to shock the audience. We all have seen how a   36  performer carefully steps   37  a bed of burning coals -- barefoot. Then he walks across   38  a single burn on his feet. Is it mind over matter, or is it just physics? As it turns   __39 , walking on burning coals isn’t that hot as   40 . “The coals are hot enough to   41__  you, but if you walk quickly across them you   42  being burned.” says Jonathan Hall, a physician at Penn State University in Eric Pennsylvania.
That’s because some coals are made   43   burning wood chips. Wood has two   44__   properties（特性）for fire-walking, explains Hall. First, wood is an insulator（絕緣體）--it doesn’t   __45  heat very well. “It   46 _ time for heat to travel   47  the wood to your feet.” Hall says. If the performer walked across red-hot metal   48 , that would truly be   49 , because metal conducts, or transmits, heat very well. The metal would   50  burn a performer’s feet.
Second, wood has a low specific heat-- it doesn’t take much heat to   51  its temperature. Heat is a form of   52 . Temperature is a   53  of heat, in units of degrees.

Our English course for kids or children focuses on learning English in an enjoyable way. Classes are small and individual attention is very important.
During the rest of the day students are encouraged to make use of the opportunities to speak and improve their English with the presence of monitors and teachers who will always use English with them.
There are three classes in the morning from Monday to Friday. The focus is primarily on spoken English; students will learn functional English to help them in real social situations. Special attention will be given to useful vocabulary for the afternoon’s activities or trip. The course will finish with a group presentation.
Maximum number of students in class is 8. This allows for greater participation and a greater degree of individual attention. Please note that this is a guaranteed maximum.
Each class is with a different teacher. This means that students practice English with the
added benefit of listening to more accents and experience a variety of teaching styles.
Classes are arranged by level. On arrival students take a level test to assess their oral, reading and written abilities. Students are then placed in a class where teachers agree they will benefit most.
We live and study on campus. There is no time wasted in traveling to class. There are short breaks between classes to allow students to refresh, prepare for the next class or make a start on homework. Homework is beneficial to reinforcing language learned during the day so teachers will set some short tasks each night. Students will have opportunity to do these when they choose--after class, before or after meals or at the end of the day.
Teachers are native-English speakers from all over the world, graduates, TESOL qualified, and experienced. Our teachers know what ifs like to learn a language. They will encourage and help all the students一from children to teenagers.

Tre’S mom，Christina Thompson, cannot believe how much her son already learned this year in his full-day, free pre-school class in Oklahoma City. “Since he’s been in school his vocabulary has increased surprisingly,” Thompson says. “The other day he came home and said, ‘You know what ，mom? You are being ridiculous，” Thompson laughs quietly. “And then he asked, ‘Do you know what ‘ridiculous’ means, mom?’” Tre knows the entire alphabet, his numbers to 100，and he’s starting to read. And letters and numbers aside, Thompson is most struck by how fast Tre is absorbing vocabulary and language.
Of course, not all pre-school is created equal. High quality pre-schools have well-trained, well-educated teachers in the classroom (much like Tre Thompson’s teacher Mrs. Wallace, who uses play-based learning to teach both academics and social skills and can rattle off (飛快說出） a battery of data on how well her students are progressing towards their year-end goals). Texas can also offer a model for educator development: its Texas School Ready! Campaign has proven to increase the quality of participating pre-schools by providing early childhood teachers with coaching, professional development, research-based curriculum (課程)，and progress monitoring. States and districts should also combine pre-school with the K-12 system, as Oklahoma does ，so that children enter kindergarten smoothly.
Oklahoma is one of the leading states in providing students like Tre with free ，full-day pre-school. And the results are already paying off: According to a 2012 study, Oklahoma kids that went through pre-school showed vocabulary gains 28% higher than those of children without pre-school, and math gains 44% higher than non-pre-school kids. And we know that high-quality pre-school doesn’t just mean higher scores in elementary school. They were more likely to have graduated from high school and less likely to have committed a violent crime. They also earned more money and were more likely to be employed.
We know pre-school works, so let’s stop talking and start building a system where all children have access to excellent early childhood education. As any well-educated four year old could tell us, not doing so would be ridiculous.
小題1:The case of Tre in the first paragraph serves as the evidence of______.
A．children’s disrespect towards parents
B．the bad performance of students at school
C．the positive effect of pre-school on children
D．Thompson’s doubt about her son’s education
小題2:At high quality pre-schools, children may learn by______
A．playingB．modellingC．researchingD．monitoring
小題3:It can be inferred that______.
A．children can not enter kindergarten without pre-school
B．Oklahoma is the best state offering full-day pre-school
C．a(chǎn)ll pre-schools have well-trained, well-educated teachers
D．kids with pre-school may be better equipped for their future
小題4:What would be the best title for the passage?
A．Not all pre-school works
B．All pre-school is created equal
C．We owe our kids universal pre-school
D．Pre-school goes well with K-12 system
