Feeling lonely can make you sick. Doctors have long known that loneliness can cause many health problems and even death. What they didn’t know is   16  this feeling causes illness. A study in the online magazine Genome Biology  17  that loneliness actually influences the important part of our bodies—our genes.
In a small population of patients, researchers   18  more than 20,000 genes to compare how the genes of lonely and non-lonely individuals (個(gè)體) express themselves in molecular processes (分子過程) and in personal health. They found that gene expression is   19  in chronically (長(zhǎng)期地) lonely people. “We now have a new way for understanding the relationship   20   social experience and physical health,” explains the study’s lead author, Steve Cole of University of California, Los Angeles.
“This study—the first to link (聯(lián)系)   21  with gene changes—is special and exciting,” says Emma Adam, a professor of human development at Northwestern University. “It   22  in the black box.”
According to John Cacioppo, an author of the study from the University of Chicago, the
work suggests that loneliness is a warning   23 , much like physical pain. “This feeling is so bad because   24  of us wants to be forgotten; that’ s also what human means,” he says. “It makes us   25  for other people and want to be with friends when we’re lonely.”

It was unusually quiet in the emergency room on December 25.

I was the nurse on duty that day. I didn't think there would be any patients. Just then five bodies   1    at my desk, a pale woman and four small children.

“Are you all sick?” I asked.

“Yes,” she said   2   , lowering her head.

But when they described their problems, things got a little strange. Two of the children had headaches, but they didn’t show any    3  of headaches at all. Two children had earaches, but only one could tell me which ear was affected. The mother  4  of a cough but seemed to work to produce it.

I didn't say anything,  5 I explained that they might wait for a little while before a doctor saw her. She answered, “Take your time; it's warm here.”

I checked the chart after another nurse had finished registering(登記) the family. No 6  —they were homeless. The waiting room was warm.

I looked at the family by the Christmas tree. The littlest one was pointing at the television and saying something to her mother. The oldest one was looking at lights on the Christmas tree.

I went back to the nurses' station and mentioned we had a homeless family in the waiting room. The nurses who felt bored with  7  Christmas, turned to compassion((憐憫) for the family just trying to get warm on Christmas. The team went into action. We began to prepare a party for our Christmas  8 . We needed presents. We put together oranges and apples in a basket. We collected from different departments candies, crayons and other things available that could be presents.

   9 , as the family walked to the door to leave, the four-year-old child came running back, gave me a hug and    10 , “Thanks for being our angels today.”

One in four Chinese primary school students say they are too busy to eat fruit every day, while many dislike fruit for the simple reason that their __16__tell them to eat it.
That is the result of a recent survey __17__the Chinese Association for Student Nutrition & Health Promotion(中國(guó)學(xué)生營(yíng)養(yǎng)和健康促進(jìn)協(xié)會(huì)), who last month issued a questionnaire among 1,500 children in Beijing, Shanghai and Guangzhou. They__18___ 28 percent didn't eat fruit every day and of those who did, one in seven did not eat enough.
Among students who didn't eat fruit every day, 50 percent said it was because they "didn't have time" and 40 percent of those who didn't like fruit said it was because "my parents____19___ me to".
"Fruit is a natural source of many nutritional elements(營(yíng)養(yǎng)元素), can balance a person's nutritional intake and help to ___20___overweight(超重)," says Association director Du Yuxia.
He says about 20 percent of primary school students in Beijing and Guangzhou are overweight, while the figure is  __21___30 percent in Shanghai.
Hu Xiaoqi, a nutrition expert with the Chinese Center for Disease Control and Prevention (CDC), believes a student should eat at least 150 grams of fruit a day. Moreover, fruit juice is not an adequate substitute because the fruit __22__ contains more fiber and vitamins than juices, which are usually high in sugar and contain preservatives.
Hu says primary school students should be encouraged to eat one or two fruits every day. ___23___many students found they didn't have time to eat fruit before breakfast or in the evening, they should be encouraged to ___24__fruit to school and eat it during class breaks . Finally, she suggests that parents encourage their children to eat fruit, instead of forcing them.
Ma Guansheng, deputy ___25____of the CDC's Nutrition and Food Safety Institution(營(yíng)養(yǎng)和食品安全機(jī)構(gòu)), says: "6-12 years old is a crucial time for physical development. Children at this age need an adequate and balanced nutritional supply to guarantee the normal growth of the body."
