    DNA is the whole “map” of the human body. It is something that all humans have, and it tells the body what to do. DNA is the reason that we look like our parents, because we get some of their DNA to make our own.

    People have been trying to understand the human body for a long time. In 1860, Mr. Mendel discovered why we look the same as other people in our family. It is because of small things called “genes”（基因）in our body. In 1953, two scientists, Watson and Crick, found out that genes are really messages. They’re written in the DNA with a special language.

    In 1961, another two scientists found the first “word” that they could understand in that language. It shows how DNA tells the cell (细胞）to build its parts. So far, scientists have found all the words in the DNA map, but we still don’t understand what they all do. By understanding what just one “word” means, we can help to save people from several illnesses. So the more we understand, the more doctors will be able to do.

    Most people hope that this will help to make better medicine and help sick people. Other people worry that when we learn more “words” and find out more information, we will use it in the wrong way. Just to make people more attractive (有吸引力的), or stop sick people getting jobs.

    A new study suggests that the more teenagers watch television, the more likely they are to develop depression (抑郁症) as young adults.
    The researchers used a national long-term survey of healthy young teenagers of about 13—16 to find out the relationship between media(媒体) use and depression. They based their findings on more than 4000 young teenagers who were not depressed when the survey began in 1995.
    As part of the survey, the young people were asked how many hours of television or videos they watched daily. They were also asked how often they played computer games and listened to the radio. Here was the result. The young people spent five and a half hours a day using media and more than 2 hours of that was spent watching TV.
    Seven years later, in 2001, more than 7% of the young people had signs of depression. The average age at that time was 21. Brian Primack at the University of Pittsburgh medical school was the lead author of the new study. He says every extra hour of television meant an 8% increase in the chances of developing signs of depression.
    The researchers say they did not find any such relationship with the use of other media such as movies, video games or radio. But the study did find that young men were more likely than young women to develop depression given the same amount of media use.
    Doctor Primack says the study did not find out if watching TV causes depression directly. But one possibility, he says, is that it may take time away from activities that could help prevent depression, like sports and social activities. It might also prevent a person from sleeping well, he says, and that could have an influence.
    The study was just published in the Archives of General Psychiatry.
    In December, the journal Social Indicators Research published a study of activities that help lead to happy lives. Researchers from the University of Maryland found that people who describe themselves as happy spend less time watching television than unhappy people. The study found that happy people are more likely to be socially active, to read, attend social services and to vote.

    阅读下面短文，在表格内的空白处填入合适的答案(每格限填一词)
    The way in which we communicate with others can be greatly improved by building a better vocabulary. In our personal life，we communicate and share experiences with others. However, how well we do it depends on(取决于)our ability to express ourselves through spoken and written language. Luckily，increasing(增加)our word power can make us own the skills we need to communicate better with others and can also help us get better results in our study.
    When you see a new word，whether through reading or hearing someone say the word，just be ready to take out your dictionary and look it up-learn about the word and anything that relates(与…相关)to it. If you understand the word, you’ll hopefully remember it well.
    Meanwhile, you’d better write down words to learn. You can go through the dictionary，magazine and newspaper or even take down the unknown words you hear. Try to review them every day-look at the words and speak them out loudly. Copy the words over and over again，along with their meanings，and you will surprisingly remember themn in no time.
    You can also do word searches，crossword puzzles or other word games. Playing these games，you are more likely to come across new words, and when you are caught in new words, study them. The more words you have in your brain’s word bank，the better you will become at these word games. You will be remembering，learning and having fun，too.
    Finally, reading is also believed to be an excellent way to learn new words and build up your vocabulary. Read things you are interested in，because in this way，you are less likely to become bored. But dont skip over(忽略) those words you don’t know. Instead, you should remember and use them in your own daily conversations. Use them more, and you’ll surely have a better chance of remembering them.
    Topic：Increasing Your Vocabulary
    【小题1】__________
    of building up vocabulary
    		●Improve your ability to express yourselves and communicate better with others.
