People born in winter are more likely to suffer mental health disorders, according to a recent study carried out by researchers at Vanderbilt University in Tennessee.
Researchers raised baby mice from birth to weaning (断奶) in either “summer” light cycles of 16 hours of light and 8 hours of dark or “winter” cycles of 8 hours of light and 16 hours of dark. A third group experienced 12 hours of light and 12 hours of dark a day.
Then half the winter mice stayed in a winter cycle, while half switched to a summer schedule. The summer mice were similarly split. The mice raised in equal periods of light and dark were split into three groups, one of which stayed on the 12hour schedule, one of which joined the winter group, and one of which joined the summer group.
After 28 days, it turns out the summerborn mice behaved the same whether they stayed on the summer cycle or switched to winter. But among the winterborn mice, those stayed in winter kept their previous schedule, while those that switched to summer stayed active for an extra hour and a half, which indicates that mice born and weaned in a winter light cycle showed dramatic disruptions in their biological clocks.
The finding is the first of its kind in mammals, and it could explain why people born in winter are at higher risk for mental health disorders including bipolar depression, schizophrenia and seasonal affective disorder.
“We know that the biological clock regulates mood in humans,”said study researcher McMahon. “If the mechanism (机制) similar to the one that we found in mice operates in humans, then it could not only have an effect on a number of behavioral disorders, but also have a more general effect on personality.”
1.How many groups of mice are there finally in all in the experiment?
A. Four. B. Five. C. Six. D. Seven.
2.What's the main idea of the text?
A. The biological clock regulates mood in humans.
B. People born in winter are at higher risk for physical health disorders.
C. Being born in winter has a negative effect on people's mental health.
D. The length of light will influence the behavior of the mice.
3.The underlined word “split”(Paragraph 3) can be replaced by ________.
A. ended B. torn C. hit D. divided
4.Who is the appropriate reader of the passage?
A. A jobhunter. B. A student in the university.
C. A newlymarried couple. D. An experienced dentist.

Babies born in summer are more likely to become short-sighted in late life, a study has shown.
As many as a quarter of all cases of short-sightedness are caused by too great an exposure to sunlight in the first weeks of life, say eye experts.
They are advising all parents to put sunglasses on their babies during the first weeks.
Scientists had already established that over-exposure to sunlight caused short-sightedness in animals.
Researchers who compared the months in which babies were born with whether they needed glasses later on say the principle also applies to humans.
A study of almost 300,000 young adults─the largest of its kind─showed that those born in June and July had a 25 per cent greater chance of becoming severely short-sighted than those born in December or January. Research leader Professor Michael Belkin, of Tel Aviv University, said it was because prolonged illumination(光照) causes the eyeball to lengthen, causing short-sightedness.
Hence the more light a newborn is exposed to, the more the eyeball lengthens and the worse the short-sightedness will be.
The mechanism which lengthens the eyeball is associated with levels of melatonin(褪黑激素), a pigment (色素) which protects the skin against harmful rays of the sun.
In young babies not enough melatonin is released as protection, meaning they are more vulnerable to sunburn and changes to eyeball shape.
Sight expert Professor Daniel O’Leary, of Anglia Ruskin University in Cambridge, said “At the moment we don’t know the precise cause of why light exposure affects sight, but the evidence seems to prove that it is one of the reasons for people becoming short-sighted.”
1. Babies born in summer are more likely to be short-sighted ____________.
A. because the summer sun is too strong for babies
B. because babies born in summer have lengthened eyeballs
C. if they are exposed to much sunlight in the first weeks after they are born
D. if parents don’t know a proper way to protect their babies’ eyes
2. Melatonin is a kind of material to ___________.
A. prevent the eyes from becoming near-sighted
B. protect the skin from harmful sun rays
C. make our body strong
D. protect babies’ eyes from summer sun
3. From what Professor Daniel O’Leary says we can conclude that ___________.
A. there is no evidence that short-sightedness is related to exposure to sunlight
B. whether light exposure affects sight still needs to be further proved
C. he believes that light exposure can cause short-sightedness
D. he tries to give the cause of why light exposure affects sight
4. The underlined word “vulnerable” in the passage probably means __________.
A. easy to be harmed B. resistant
C. protective D. changeable

Compared to people with bad attitudes,people who are cheerful and relaxed are less likely to suffer from colds,according to a new study.“It’s possible that being upbeat helps the body fight illnesses,” says Sheldon Cohen,the study’s lead researcher from Carnegie Mellon University (CMU) in Pittsburgh.
In a previous(先前的) study,Cohen and his colleagues put coldcausing viruses into the noses of 334 healthy adults. People who tended to be cheerful and lively were least likely to develop sniffles,coughs,and other cold symptoms. People who showed positive feelings were also less likely to mention symptoms to their doctors,even when medical tests detected those symptoms.
Those findings were interesting,but they didn’t prove that a person’s attitude affects whether he or she gets sick. Instead,it was still possible that a person’s underlying personality is what matters. Evidence suggests,for instance,that certain people are naturally more likely to be outgoing and optimistic,with high selfesteem and a sense of control over life. This would mean that who we are,not how we feel,ultimately decides our chances of catching colds.
To figure out which mattered more (personality or emotions),the CMU team interviewed 193 healthy adults. The researchers talked to each person over the phone every evening for 2 weeks. At the end of the interviewing period,people got nose drops that contained either cold or flu viruses. Then,each person stayed in an isolated room for 5 or 6 days. The results showed that everyone in the study was equally likely to get infected. Their symptoms,however,differed depending on the types of emotions that they had reported over the previous 2 weeks. Among those who reported good moods and had been infected with the flu virus,for example,28 percent developed coughs and stuffy noses. On the other hand,those symptoms struck 41 percent of people who had been less upbeat.
1.
What would be the best title for the passage?
A.Smiles Turn away Colds
B.An Interesting Way to Beat Colds
C.Be Outgoing and Optimistic to Fight Colds
D.What Matters More,Personality or Emotions?
2.
In the previous study,people who showed positive feelings______.
A.didn’t catch colds as often
B.developed cold symptoms more slowly
C.were less likely to have cold symptoms detected
D.were less likely to feel cold symptoms
3.
What mainly decides our chances of catching colds according to the new study?
A.Personality. B.Selfesteem(自尊). C.Emotions. D.Attitudes.
4.
The underlined word “symptoms” probably means________.
A.something that causes cold
B.something that results in cold
C.signs that something exists,especially something bad
D.changes in your body or mind that show that you are not healthy

At some point in life, many people suffer a mental problem. While most people get over it, for others it doesn't go away easily.
The World Health Organization (WHO) says that about 20 percent of children and teenagers across the globe suffer from mental illness. It's thought that the number of children and teenagers with mental illness around the world will increase by half by 2020. It will become one of the main causes of disease, disabilities and even death.
The reason for mental problems among young people may be the increasing pressure in life. Study and relationships have always caused huge stresses for school children. For instance, they experience school bullying(欺凌)and academic pressure.
In China, the picture isn't bright, either. About 30 million Chinese children and teenagers under the age of 17, or 10 percent of children and teenagers in China, have a mental health challenge, reported China Daily.
Also, according to China Daily, Chinese people don't seek help with their mental problems. They fear that others will think less of them if they admit that they are in trouble. Many Chinese people are ashamed of their mental problems and mental illness is taboo(禁忌)in any Chinese families.
In the UK, over three-quarters of young people believe their mental health problems have a social shame and a quarter of young UK people wouldn't ask for help if they developed a mental problem.
Young people who don't seek help for their condition may be creating problems for themselves in the future. If you feel something is wrong within you - seek help.
Feeling down? Here are three things to try if you feel low.
●Go to a psychology teacher. The teacher will listen to you and offer help - for free!
●Call 800-800-1100. It's the number of a hotline run by the Mental Health Research and Prevention Center. The line is open 24 hours a day.
● Tell your parents and visit the hospital if the situation gets out of control.
1.According to the WHO, about ______ of children and teenagers worldwide experience mental illness.
A. 10 percent B. one fifth
C. 30 percent D. three quarters
2.Chinese people don't ask for help with their mental health probably because ______ .
A. they think less of their mental problems
B. they fear that they may get into trouble
C. they are ashamed to admit having mental problems
D. they are unwilling to avoid their mental illness
3.School children with mental health should try the following three things EXCEPT ______ .
A. consulting their teacher
B. calling a hotline for advice
C. communicating with their parents
D. hiding their mental illness from others
4.What is the purpose in writing this article? ______
A. To analyze the major causes of young people's mental illness.
B. To describe the current situation of young people's mental health.
C. To encourage young people to deal with their mental problems properly.
