14-year-old Brooke Eriekson likes to sleep．  1 on weekends．she wants to sleep late(睡懒觉)．But Brooke's mom thinks that Brooke should get up at，the same time every day,So she'll get used to(习惯于)getting up early．

    Both(两个)Brooke and her mom are right．Sleeping late in the moming makes it more difficult to sleep at night．  2  Then it gets more difficult to get up the next morning．Getting up and going to bed at the same times every day helps the body to get enough rest(足够的休息)．

    3  They need 8 to 9 hours of sleep each night，rbut many of them can only get 6 to 7 hours of sleep on school nights．If someone doesn't have enough sleep for a long time，he may feel tired and not happy，and be easier to get ill．Being tired makes it more difficult to remember things，to do well in school and to do well in sports and other activities．

    On June 26th, 2000, two scientists, called Francis Collins and Craig Venter, told the world that they could now read the whole “map” of the human body: DNA. DNA is something that all humans have, and it tells the body what to do. DNA is the reason that we look like our mother and father, because we get some of their DNA to make our own. Now we can read some of this “map”, and so we can find out more about how our bodies work.

    People have been trying to understand the human body for a long time. In 1860, Gregory Mendel discovered that there is a special reason why we look the same as other people in our family. It is because of small things called “genes” that we have in our body. In 1953, James Watson and Francis Crick made another discovery and found out that those small parts are really messages written in the DNA with a special language.

    In 1961, Marshall Nirenberg and Johann Matthaei found the first “word” that they could understand in that language, showing how DNA tells the cell to build its parts. This meant that one day we would be able to read all the messages that a human body gets from its parents' bodies. Scientists have now found all the words in DNA map, but we still do not understand what they all do. By understanding what just one “word” means, we can help save people from several diseases. 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 people who are very ill. Other people worry about that when we learn more words and find out lots of other information, we still use it in the wrong way, just to make people more attractive, or stop sick people getting jobs.

    Cars are very important in the life of the Americans. ⑴Without a car, most American people would feel that they are poor. And even if a person is poor, he doesn't really feel poor when he has a car. ⑵Henry Ford was the man who started making cars in large numbers. He probably didn't know how much cars would affect the American culture. Cars have made the United States a nation on wheels. And ⑶it has helped to make the United States what it is today.

    There was a park near my home. Many people said there was nothing special there. One afternoon I went into the park. {#blank#}1{#/blank#} "Which way should I go?" I asked myself. The two paths(小路) were different from each other.

    The left one was wide and clean. {#blank#}2{#/blank#} The flowers were very beautiful. I decided to take this path. But wait! I looked at the right one. It was not clean. For a long time I couldn't decide which path to choose.

    {#blank#}3{#/blank#} It wasn't nice, but I didn't want to give up. At last I came to the end of the path. Ah! There was a small garden there. It was beautiful. I thought it was the nicest part of the park. When I told them what I had seen in the park, they just smiled at me without saying a word.

    My trip to the park made me understand something about life. {#blank#}5{#/blank#} You may get a big surprise!
