People who averaged fewer than seven hours of sleep per night in the weeks before being exposed to the cold virus were nearly three times as likely to get sick as those who averaged eight hours or more, a new study found.
Researchers used frequent telephone interviews to track the sleep habits of more than 150 men and women aged 21 to 55 over the last few weeks. Then they exposed the subjects to the virus, quarantined (检疫隔离) them for five days and kept track of who got sick.
Besides sleeping more, sleeping better also seemed to help the body fight illness: Patients who fared better on a measure known as “sleep efficiency”—the percentage of time in bed that you’re actually sleeping—were also less likely to get sick.
The results held true even after researchers adjusted for elements such as body-mass index, age, sex, smoking and pre-existing antibodies (抗体) to the virus.
The researchers aren’t exactly sure why sleeping better makes you less likely to develop a cold. But they do try to give an answer: “Sleep disturbance influences the regulation of symptom mediators (调节因子) that are released in response to infection.” In plain English, maybe tossing and turning when you’re infected with the cold virus contributes to the symptoms that define a cold.
The researchers were based at Carnegie Mellon, the University of Pittsburgh and the University of Virginia, and the study was funded by the National Institutes of Health.
1. According to the passage, what does the underlined word “subjects” mean in paragraph 2?

High school dropouts earn an average of $9,000 less per year than graduates. Now a new study denies a common belief why they quit. It’s much more basic than flunking out(不及格).
Society tends to think of high school dropouts as kids who just can’t make it. They are lazy, and perhaps not too bright. So researchers were surprised when they asked more than 450 kids who quit school about why they left.
“The vast majority actually had passing grades and they were confident that they could have graduated from high school.”John Bridgeland, the executive researcher said. About 1 million teens leave school each year. Only about half of African-American and Hispanic(美籍西班牙的)students will receive a diploma, and actually all dropouts come to regret their decision. So, if failing grades don’t explain why these kids quit, what does? Again, John Bridgeland:“The most dependable finding was that they were bored.”“They found classes uninteresting；they weren’t inspired or motivated. They didn’t see any direct connection between what they were learning in the classroom to their own lives, or to their career aspirations.”
The study found that most teens who do drop out wait until they turn sixteen, which happens to be the age at which most states allow students to quit. In the US, only one state, New Mexico, has a law requiring teenagers to stay in high school until they graduate. Only four states: California, Tennessee, Texas and Utah, plus the District of Columbia, require school attendance until age 18, no exceptions. Jeffrey Garin, another researcher, says raising the compulsory attendance age may be one way to keep more kids in school.
“As these dropouts look back, they realize they’ve made a mistake. And anything that sort of gives these people an extra push to stick it out and see it through to the end, is probably helpful measure.”
New Hampshire may be the next state to raise its school attendance age to 18.But critics say that forcing the students unwilling to continue their studies to stay in school misses the point—the need for reform. It’s been called for to reinvent high school education to make it more challenging and relevant, and to ensure that kids who do stick it out receive a diploma that actually means something.
1.Most high school students drop out of school because_______.
A. they have failing grades
B. they take no interest in classes
C. they are mistreated
D. they are lazy and not intelligent
2.According to the passage, which state has a law requiring school attendance until they graduate?
A. New Hampshire
B. Utah
C. New Mexico
D. The District of Columbia
3.The underlined words“stick it out”probably means“________”.
A. complete schooling
B. solve the problem
C. love having classes
D. believe in themselves
4.In the last paragraph, the writer is trying to________.
A. analyze the reason why students quit school
B. suggest raising the compulsory attendance age
C. raise awareness of reforming high school education
D. wish to make laws to guarantee no dropout

We live in a sweet world. The average American kid consumes more than 20 teaspoons of sugar per day, and adults eat 50% more sugar today than they did in the 1970s. We all know that too much sugar isn’t good for you. But did we know it could be dangerous? A team of researchers at the University of Utah used mice to conduct a study on the negative effects of sugar. They found it could have serious effects on people’s health.
Sugar is found not only in sweets and candies, but also in many household items like pasta and crackers.
During the 58-week-long study, mice were fed a diet containing 25% more sugar. This percentage equals a healthy human diet along with three cans of soda daily. The team found that these mice were twice as likely to die as mice fed a similar diet without the sugar. Though the mice did not show signs of obesity or high blood pressure, male mice were 26% less territorial and produced 25% fewer offspring than the other mice.
Scientists often use mice for research because they have a similar genetic（基因） structure to humans. “Since most substances that are dangerous in mice are also dangerous in people, it’s likely that those physical problems that cause those mice to have increased deaths also work in people,” says study author James Ruff of the University of Utah. Findings from this study reveal negative effects that are not as noticeable as weight gain or heart problems. Sugar can contribute to long-term changes in the body that can change development and even shorten lives.
Cutting sugar out of the American diet altogether may be difficult. But making the effort to control our nation’s sugar desire will provide for a truly sweeter future.
1.The study conducted by researchers aimed at learning about________
A. the advantages and disadvantages of sugar
B. the negative effects of sugar on people’s health
C. the genetic structure of mice
D. American’s diet
2.According to the study, which of the following statements is wrong?
A. Sugar can even shorten lives.
B. Sugar’s negative effects are not noticeable.
C. Mice are more likely to diet when fed a diet containing 25% more sugar.
D. Eating much more sugar can make mice put on weight and get high blood pressure.
3.From the passage we can infer_______
A. sugar plays a very important role in Americans’ diet
B. kids consume more sugar than adults in America
C. the study on human beings lasted 58 weeks
D. the genetic structure of mice is totally different from that of people
4.What’s the best title of the passage?
A. Living a sweet life
B. Kids consume much more sugar
C. Genetic structure of humans
D. Danger of sugar

高三英语单项填空中等难度题查看答案及解析
Many people spend more than four hours per day on WeChat, and it is redefining the word “friend.” Does friending someone on social media make him or her your friend in real life?
Robin Dunbar, a professor at Oxford University, found that only 15, of the 150 Facebook friends the average user has, could be counted as actual friends and only five as close friends. WeChat may show a similar pattern.
Those, with whom you attended a course together, applied for the same part-time job, went to a party and intended to cooperate but failed, take up most of your WeChat friends. In chat records, the only message may be a system notice, “You have accepted somebody’s friend request”. Sometimes when seeing some photos shared on “Moments”, you even need several minutes to think about when you became friends. Also, you may be disturbed by mass messages sent from your unfamiliar “friends”, including requests for voting for their children or friends, links from Pinduoduo.com (a Chinese e-commerce platform that allows users to buy items at lower prices if they purchase in groups) and cookie-cutter blessings in holidays.
You would have thought about deleting this type of “friends” and sort out your connections. But actually you did not do that as you were taught that social networking is valuable to one’s success. Besides, it would be really awkward if they found that you have unfriended them already. Then, you keep increasing your “friends” in social media and click “like” on some pictures that you are not really interested. But the fact is that deep emotional connections do not come with the increasing number of your friends in social media.
If the number of your friends reaches 150, maintaining these relationships can be tough to you, and sometimes even will make you anxious. According to Robin Dunbar, 150 is the limit of the number of people with whom one can maintain stable social relationships.
1.What can we learn from Robin Dunbar’s finding in Paragraph 2?
A.A Facebook user has 250 friends on average.
B.Most of the social media friends can be actual friends.
C.Among our social media friends, only a few people matter.
D.Only 15 people of a person’s Facebook friends can be close friends.
2.What does the third paragraph tell us about most of your WeChat friends?
A.You have deep communication with them.
B.You benefit a lot from their mass messages.
C.You just have a nodding acquaintance with them.
D.You become friends with them in important occasions.
3.What can we infer from the last paragraph?
A.We will be anxious if we make friends online.
B.We should avoid making any friends in social media.
C.We should make as many friends as possible in social media.
D.We have difficulty managing relationships with over 150 people.
