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, In1860, 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 those small parts are really messages . They’re written in the DNA with a special language.
In1961, 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 do not understand what they all do. By understanding what just one “word ”means, we can help to save people from several illness. 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.

One night I was sitting in my room half-listening as my 15-year-old brother Tommy fought with my 12-year-old brother Kevin. I didn’t pay attention when Kevin rushed up the stairs with the hurt on his face.
About 20 minutes later, as I was walking upstairs I heard Kevin crying inside the bathroom. I knocked on the door and asked, “Hey Kevin, do you want to talk?”
No answer.
I tried again, “Why don’t you come out of there?”
Again, no answer.
So, joking around, I grabbed a stack of (一摞)cards and a pencil and wrote, “If you don’t want to talk, we can write notes to each other.”
An hour later I was still sitting on the floor outside the bathroom with two stacks of cards in front of me. One was blank and one was cards from Kevin on which he had translated all his yucky feelings into words for me. As I read one of Kevin’s notes, tears came to my eyes. It said, “Nobody in this family cares about me. I’m not the youngest, and I’m not the oldest. Tommy thinks I’m silly and Dad wishes he had the other Kevin as a kid because he’s better at basketball. And you’re never around to even notice me.”
Tears came to my eyes as I wrote back to him. “You know Kevin, I really do love you and I’m sorry I don’t always show it. I am here for you and you are loved in this family.”
There was no answer for a while, but then I heard a tearing sound coming from inside the bathroom. Kevin, who had run out of cards wrote on a torn paper cup. “Thanks.”
I wrote back “For what?” it returned to me with “Loving me” on it.
Since then, I try my best to never only half-notice my family members any more. Kevin and I have a closer relationship now. And sometimes when one of us notices that the other is upset, we’ll smile and say “Write it on a paper cup.”The underlined word “yucky” most probably means ____.

As we know, there are differences between western culture and Chinese culture. We can see differences when we pay attention to the way words are used. Let’s look at the words about animals and plants. Most expressions in Chinese about the dog, for example, “a homeless dog”, “a mad dog”, “a running dog” and “a dog catching mouse”, have negative meanings. But in western countries, dogs are thought to be honest and good friends of humans. In English, people use the dog to describe positive actions. For example, “You are a lucky dog.” means you are a lucky person. And “every dog has its day.” means each person has good luck sometimes. To describe a person’s serious illness, they say “sick as a dog”. The word “dog-tired” means very tired. However, Chinese love cats very much. But in western culture, “cat” is often used to describe a woman who is cruel.
