Spider monkeys have long, thin arms with hooklike hands that allow them to swing through the trees. They do not have opposable thumbs(对生拇指).
The brown-headed spider monkey has a prehensile(缠绕性的)tail, which means it can grasp and can be used like a fifth leg to grab trees. During the day, the spider monkey searches for fruits, which make up the main part of its diet. They will also eat flowers, seeds, leaves, and small insects during the dry season when fruits aren’t available. They spend most of the daylight hours climbing and swinging through the high branches of trees.
The brown-headed spider monkey lives in a large community of about 20 to 100 male and female monkeys. They split into smaller groups for feeding. Females usually give birth to only a single baby each year or two. Young monkeys are carried on their mothers’ stomachs until about 16 weeks old. Then they are strong enough to ride on their mothers’ backs. All brown-headed spider monkey babies are born with a pink face and ears.
Spider monkeys hug each other and wrap their tails around each other. They are very intelligent and have strong memories. They were named spider monkeys because they look like spiders as they hang upside down from their tails with arms and legs swinging. Their genus (属)name is Ateles, which means “imperfect”. This refers to the fact that they don’t have thumbs.
Hunting the brown-headed spider monkey is now barred in Ecuador, a country in northwestern South America, but humans have killed them for their meat for hundreds of years.
1.Spider monkeys live mostly on ________.
A. insects B. fruits
C. flowers D. leaves
2.What can we learn about spider monkeys?
A. They have five legs
B. They live in small groups
C. Their tails can take their weight
D. Their genus is the same as spiders’
3.What does the underlined word “barred” in the best paragraph refer to?
A. Permitted B. Forbidden
C. Encouraged D. Ignored
4.Where do newly-born spider monkeys stay?
A. In a large community
B. In trees with high branches

The spiders have long, scary legs. Some spiders even bite. But Spider-Man is another story. He might help people see spiders less negatively, a new study finds.
After Menachem Ben-Ezra, a proud fan of the Marvel (漫威漫画公司)films and also a psychologist. saw the movie Ant-Man and the Wasp (黄蜂), lie walked out with a sudden scientific idea that he should measure people before they went into the theater, and afterwards to see if the fear of ants would be reduced or changed.
Ben-Ezra and his colleagues asked 424 people questions, about one-quarter of them about spiders, such as “Did they find them scary?” “Did seeing one make their hearts race and palms sweat?” A second group received similar questions, this time about ants. The last two groups got the same questions about other insects. Afterward, everyone watched videos. Group one got a Spider-Man movie. Group two saw Ant-Man and the Wasp. Groups three and four watched unrelated video-wheat waving peacefully in the breeze.
After viewing the movie, Ben-Ezra again asked the participants how they felt about spiders, ants or insects in general-and found the ant and spider exposures seemed to make people insensitive and less afraid. Between 3.5 and 6.1 percent of people experience such a phobia (恐惧症) of spiders. Phobias can stop people from traveling, working and enjoying their lives.
Ben-Ezra hopes that their movie research might help people with phobias. But they caution that people with phobias shouldn’t just run out and watch movies and expect their fears to go away. “What we did is only the first step in a very long road.” Ben-Ezra says. “We didn’t say you’ll be cured. We don’t have evidence for that.” But eventually, presenting people’s fears in a positive context-such as a superhero movie—might help people surmount their fear or disgust. After all, if spiders produce Spicier-Man, maybe they’re not so bad.
1.How did Ben-Ezra conduct the study?
A.By doing lab experiments. B.By asking questions.
C.By analyzing former data. D.By observation.
2.What does the underlined word“surmount” in the last paragraph mean?
A.Delete. B.Regain.
C.Discover. D.Overcome.
3.What did Ben-Ezra advise people to do with phobias?
A.They should not try to face their phobias.
B.They should travel, work and enjoy their lives.
C.They should adopt a positive attitude to their fear.
D.They must keep away from the insects they fear.
4.What is the best title for the text?
A.The Movies about the Insect Fear
B.The Positive Energy of Superheroes
C.The Cartoon Characters Made by Marvel
D.Fighting Spider Fear with Spider-Man

US scientists say they have poured cold water on the theory that washing hands with hot water kills more germs (细菌) than unheated water. The small study of 20 people found using water at 15C (59F) left hands as clean as water heated to 38C (100F).
National Health Service (NHS) recommends that people wash their hands in either cold or warm water. In this study, scientists at Rutgers University-New Brunswick wanted to find out if popular assumptions about the benefits of warm or hot water and official guidance on hot water —given to the food industry in the US - held true. They asked 20 people to wash their hands 20 times each with water that was 15C (59F), 26C (79F) or 38 degrees (100F). Volunteers were also asked to experiment with varying amounts of soap. Before they started the tests, their hands were covered in harmless bugs. Researchers say there was no difference in the amount of bugs removed as the temperature of the water or the amount of soap changed.
Prof Donald Schaffner said: “People need to feel comfortable when they are washing their hands but as far as effectiveness goes, this study shows us that the temperature of the water used did not matter.”
However, the researchers accept their study is small and say more extensive work is needed to determine the best ways to remove harmful bacteria.
In the UK, NHS experts say people can use cold or hot water to wash their hands. They say hands should be washed for at least 20 seconds and stress the importance of using enough soap to cover the whole surface of the hands. Their guidance focuses on rubbing hands together in various .ways to make sure each surface of each hand is clean.
1.What does the underlined phrase “poured cold water” in Paragraph 1 probably mean?
A. Proved. B. Created.
C. Contradicted. D. Accepted.
2.After they washed their hands with either hot or cold water, .
A. volunteers nearly had the same amount of germ removed
B. volunteers all talked about American food industry
C. volunteers still had much germ on their hands
D. volunteers all didn’t feel very comfortable

Do People Need Small Talk to Be Happy?
Psychologists (心理学家)have long said that connecting with others is an important part of happiness, but just how much conversation we require is under examination. In one study, researchers found that small talk made up only 10% of their conversation related with happiness.
1.. Scientists believe that small talk could promote bonding. Late last year, Princeton researchers reported that small talk keeps closeness with loved ones, and isn’t merely the stuff of awkward exchanges with strangers.
Still, chatting with strangers could brighten your morning. In a series of experiments, psychologists gave Chicago passengers different directions about whether to talk with fellow passengers一something they typically avoided.2.. None of the chatters reported being rejected.
Small talk can also help us feel connected to our surroundings. People who smiled at,made eye contact with, and briefly spoke with their Starbucks baristas (服务员)reported a greater sense of belonging than those who rushed through the transaction (交易).3.One report found that when volunteers broke the silence to chat with gallery goers, the visitors felt happier and more connected to the exhibit than those who were not approached.
4..In one study, people who were rated “less curious” by researchers had trouble getting a conversation rolling on their own, and had greater luck building closeness with others when they were supplied with questions that encouraged personal disclosure (透露).But people who were considered “curious” needed no help when transforming conversations about ordinary things into personal exchanges. 5..
A. The same is true of gallery goers.
B. They found that small talk is related with happiness
C. But don’t play down small talk just yet..
D. Of course, some people are better than others at turning small talk into something bigger.
E. A “curious mindset”,the author concluded, can lead to “positive social interactions”.
F. Making small talk is an important skill for all the social situations.
G. Those told to chat with others reported a more pleasant journey.

Animal .lovers have long suspected that playing with pups was good for the soul, and now science has confirmed it – for students in particular.
The results of a new study done by researchers at the University of British Columbia concluded that the college students who spent time at drop-in dog therapy sessions experienced an increase in feelings of wellness and a reduction in overall stress. The study, as reported by Science Daily, indicates that playing with pups is not only popular with the students, it’s also beneficial to their health. This finding was seen across gender(性别).
The study, which published on March 12 in the journal Stress and Health, involved 246 students who were surveyed before and after they dropped by dog therapy sessions. The young participants were given free access to pet, hug with and talk to seven to 12 therapy dogs. Additionally, they filled out questionnaires right before and right after hanging with the dogs, as well as 10 hours later.
According to researchers, these young adults reported a notable increase in happiness, a significant reduction in stress and a flood of energy right after their sessions with the pups. Although the reported feelings of happiness and satisfaction weren’t long-lasting, researchers say other effects have clear, positive advantages.
“These sessions clearly provide benefits for students in the short-term, so we think universities should try to schedule them during particularly stressful times, such as around exam periods,” Assistant Professor of Psychology at UBC and the study’s senior author, Frances Chen told Science Daily. “Even having therapy dogs around while students are working on their out-of-class assignments could be helpful.”
1.What does the new study say about the pups?
A. They are only good for college students.
B. They are only beneficial to the students’ physical health.
C. They can increase happiness and satisfaction.
D. They can create positive feelings that last very long.
2.What does the author of study advise universities to do?
A. Allow their students to have therapy dogs to avoid acute stress.
B. Allow their students to have therapy dogs around during each exam.
C. Allow their students to have therapy dogs around during their class.
D. Allow their students to have therapy dogs to achieve good grades.
3.What can we infer from Paragraph 2?
A. College students like to play with pups.
B. Dog therapy sessions are popular among college students.
C. People especially college students are under great pressure.
D. Playing with pups benefits males and females mentally.
4.What may be the best title for the text?
A. Pups, best friends of humans. B. Pups, therapies for students.
C. Animal lovers and pups D. Pets keeping and the soul

The aye-aye, in the same family as people, monkeys and apes, is about 40 cm long, with a bushy tale about the same length as the body. The dark brown fur is long and woolly, giving the animal a rather shaggy(蓬松的) appearance. They are found only on Madagascar, an island off the coast of Africa. It lives in the tropical forests in the east and north of Madagascar.
The aye-aye is mostly arboreal(栖息在树上的), but is sometimes seen walking on the ground. It’s active during the night, looking around in the trees for food. The aye-aye is actually the largest primate(灵长类动物) active during the night. Large eyes help the aye-aye find its way about at night. During the day, the aye-aye sleeps in a nest in a tree. Aye-ayes spend almost the whole night travelling about and feeding.
Aye-ayes live alone. Sometimes pairs are seen, but basically little is about their lives. They don’t Icap and cling to trees like primates. They move about on all four legs.They occasionally make brief cries but are silent. Worms inside dead wood form the largest part Of the aye-aye diet. The aye-aye also feeds on fruit, eggs, and bamboo shoots.
The front feet of the aye-aye are unique. All the toes are long and thin, but the third is exceptionally long. The aye-aye taps on the tree trunk and listens for movement as searches places "‘here worms might-be located. It bites at the tree to make homes. then it uses its third finger to reach inside and hook out worms, The front teeth of the aye-aye grow continuously and are worn down by its eating at bark in its search for worms.
Aye-ayes are close to be gone or totally gone. Because of deforestation (伐木), or forest destruction, the animals have therefore been forced to eat villagers’ crops, and many aye-ayes been have been killed while doing In addition. some people on Madagascar believe that seeing an aye-aye is a sign that someone close to them will die, so they kill the animals on sight.

Monkeys seem to have a way with numbers.
A team of researchers trained three Rhesus monkeys to associate 26 clearly different symbols consisting of numbers and selective letters with 0-25 drops of water or juice as a reward. The researchers then tested how the monkeys combined—or added—the symbols to get the reward.
Here’s how Harvard Medical School scientist Margaret Livingstone, who led the team, described the experiment: In their cages the monkeys were provided with touch screens. On one part of the screen, a symbol would appear, and on the other side two symbols inside a circle were shown. For example, the number 7 would flash on one side of the screen and the other end would have 9 and 8. If the monkeys touched the left side of the screen they would be rewarded with seven drops of water or juice; if they went for the circle, they would be rewarded with the sum of the numbers—17 in this example.
After running hundreds of tests, the researchers noted that the monkeys would go for the higher values more than half the time, indicating that they were performing a calculation, not just memorizing the value of each combination.
When the team examined the results of the experiment more closely, they noticed that the monkeys tended to underestimate(低估) a sum compared with a single symbol when the two were close in value—sometimes choosing, for example, a 13 over the sum of 8 and 6. The underestimation was systematic: When adding two numbers, the monkeys always paid attention to the larger of the two, and then added only a fraction(小部分) of the smaller number to it.
“This indicates that there is a certain way quantity is represented in their brains, ”Dr. Livingstone says. “But in this experiment what they’re doing is paying more attention to the big number than the little one.”
1.What did the researchers do to the monkeys before testing them?
A.They fed them. B.They named them.
C.They trained them. D.They measured them.
2.How did the monkeys get their reward in the experiment?
A.By drawing a circle. B.By touching a screen.
C.By watching videos. D.By mixing two drinks.
3.What did Livingstone’s team find about the monkeys?
A.They could perform basic addition. B.They could understand simple words.
C.They could memorize numbers easily. D.They could hold their attention for long.
4.In which section of a newspaper may this text appear?
A.Entertainment. B.Health. C.Education. D.Science.

Chinese scientists recently have produced two monkeys with the same gene, Zhong Zhong and Hua Hua, using the same technique that gave us Dolly the sheep. These monkeys are not actually the first primates(灵长类)to be cloned. Another one named Tetra was produced in the late 1990s by embryo(胚胎)splitting, the division of an early-stage embryo into two or four separate cells to make clones. By contrast, they were each made by replacing an egg cell nucleus(原子核)with DNA from a differentiated body cell. This Dolly method, known as somatic cell nuclear transfer(SCNT), can create more clones and allows researchers greater control over the edits they make to the DNA.
Success came from adopting several new techniques. These included a new type of microscopy to better view the cells during handling or using several materials that encourage cell reprogramming, which hadn’t been tried before on primates. Still, the research process proved difficult, and many attempts by the team failed. Just two healthy baby monkeys born from more than 60 tested mothers. This leads to many researchers’ pouring water on the idea that the team’s results bring scientists closer to cloning humans. They thought this work is not a stepping stone to establishing methods for obtaining live born human clones. Instead, this clearly remains a very foolish thing to attempt, it would be far too inefficient, far too unsafe, and it is also pointless.
But the scientists involved emphasize that this is not their goal. There is now no barrier for cloning primate species, thus cloning humans is closer to reality. However, their research purpose is entirely for producing non-human primate models for human diseases; they absolutely have no intention, and society will not permit this work to be extended to humans. Despite limitations, they treat this breakthrough a novel model system for scientists studying human biology and disease.
1.What do we know about the technology called SCNT?
A. It created the first two primates.
B. It may contribute to editing the DNA.
C. It can divide an early-stage embryo into several cells.
D. It produced two cloned monkeys with different genes.
2.What does the author mean by “pouring water on the idea” in paragraph 2?
A. Keeping a hot topic of it.
B. Attaching no importance to it.
C. Having a low opinion of it.
D. Adding supportive evidence to it.
3.What is the scientists’ purpose to clone these monkeys?
A. To prepare for their research on human cloning.
B. To serve as a stepping stone to their reputation.
C. To help with the study of human diseases.
D. To raise money for holding an exhibition of novels.
4.What can we infer from the passage?
A. Cloning humans is already on its way.
B. New techniques seem to be pointless.
C. Society won’t agree to clone another monkey.
D. The success rate of cloning a monkey was not high.
