Question: Read the article and select the best answer. Article: It never occurred to Sun Yukun that the decision he made four years ago would have an impact on his career. When the 22-year-old entered college in 2009, he decided not to change his rural residence to a students' collective one. But when he finished college and was offered a job with a state-owned enterprise in Beijing, Sun was told that he couldn't accept the offer unless he had an urban hukou (household registration record). This time, he had no choice but to change his residence status. Transferring hukou to a university became optional in 2003, and many students are confronted with the dilemma of whether to do so or not. Professionals suggest they make the decision based on their current situation and future plans. 'I regret transferring my hukou' Wang Jinbi, 20, is an accounting major at Beijing Union University. Coming from Chifeng, Inner Mongolia autonomous region, she transferred her hukou when she enrolled at university. "I didn't think it was a big deal," Wang says. "Since I'm registering under an urban hukou, it doesn't matter whether it's in Beijing or Inner Mongolia, I thought." What Wang didn't expect, however, is that she would regret her decision later. "After two years of study, I've figured out my future plans. I want to return to my hometown and make a living there," she says. That means Wang needs to transfer her hukou back again, which she worries will be a troublesome procedure. "I have a friend who graduated last year. She spent a lot of time and energy transferring her hukou back to her hometown again due to complicated paperworks," says Wang. Guidelines for transferring hukou Wang's experience is not uncommon. Many students don't know what their decision means for their future. In order to help these students, Xie Yongqiang, from the Chengdu Municipal Bureau of Justice, posted a guideline for transferring hukou on a micro blog. According to Xie, students should firstly think about where they're going to stay. "If you like the city where you're studying and are considering staying... Question: Under which circumstance can we NOT transfer our hukou? Options: A: If you want to stay at the city where you are studying. B: If you want to participate in an exchange program. C: If you want a better future. D: If your family has land and a house and will get a share of compensation due to a forced relocation.

Read the article and select the best answer. Article: The baby monkey is much more developed at brith than the human baby. Almost from the moment it is born,the baby monkey can move around and hold tightly to its mother. During the first few days of its life the baby will approach and hold onto almost any large,warm, and soft object in its environment , particularly if that object also gives it milk. After a week or so , however, the baby monkey begins to avoid newcomers and focuses its attentions on "mother"-----the real mother or the mother-substitute . During the first two weeks of its life warmth is perhaps the most important psychological thing that a monkey mother has to give to its baby. The Harlows, a couple who are both psychologists, discovered this fact by offering baby monkeys a choice of two types of mother-substitutes ----one covered with cloth and one make of bare wire. IF the two artificial mothers were both the same temperature, the little monkeys always preferred the cloth mother. However, if the wire model was heated, while the cloth model was cool, for the first two weeks after brith the baby monkeys picked the warm wire mother-substitutes as their favorites. Thereafter they switched and spent most of their time on the more comfortable cloth mother. Why is cloth preferable to bare wire? Sometime that the Harlows called contact comfort seems to be the answer, and a most powerful influence it is. Baby monkeys spend much of their time rubbing against their mothers' skins, putting themselves in as close contact with the parent as they can. Whenever the young animal is frightened, disturbed, or annoyed, it typically rushes to its mother and rubs itself against her body. Wire does n't "rub"as well as does soft cloth. Prolonged "contact comfort" with a cloth mother appears to give the babies confidence and is much more rewarding to them than is either warmth or milk. According to the Harlows, the basic quality of a baby's love for its mother is trust. If the baby is put into an unfamiliar playroom without its mother, the baby ignores the toys no... Question: It can be inferred that when the baby monkey feels secure,  _  . Options: A: it frequently rushes back for a deep embrace when exploring the toys B: it spend more time screaming to get rewards C: it is less attracted to the toys though they are interesting D: it cares less about whether its mother is still around

Article: Not all think laughter is the best medicine, but it seems to help.So scientists carried on a new study of diabetes   patients who were given a good dose of humor for a year to prove it. Researchers divide 20 high-risk diabetic patients into two groups.Both groups were given standard diabetes medicine.Group L viewed 30 minutes of humor of their choice, while Group C, the control group, did not.This went on for a year of treatments. By two months into the study, the patients in the laughter group had lower level of the hormones epinephrine  , considered to cause stress, which is known to be deadly.After the 12 months, _ rises 26 percent in Group L but only 3 percent in Group C.In another measure, C-reactive proteins, a maker of heart disease, drop 66 percent in the laughter group but only 26 percent in the control group. "The best doctors believe that there is a physical good brought about by the positive emotion, happy laughter," said study leader Lee Berk of Loma Linda University.And other research has found that humor makes us more hopeful.Still, more study is needed, Berk said.The research by Berk found that humor can bring about similar changes in body chemistry, which was proved in the new study.The research result will be presented this month at the meeting in the US.Research at the University of Maryland School of Medicine shows that laughter causes the inner lining of blood vessels to expand, increasing blood flow in a way thought to be healthy. "Lifestyle choices have an important effect on health and these are choices which we and patients should pay attention to, rather than prevention and treatment," Berk said in a statement this week. Question: In what way does laughter benefit people's health? Options: A: Blood is made thick by laughter. B: Laughter makes blood vessels thin. C: Laughter increases blood pressure. D: Laughter makes blood flow fast.
