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.

Have you ever wondered why you can speak Chinese well but find it hard to speak English? Maybe you think it's easier than English. You are wrong! Chinese seems easy because you've spoken it since childhood. Now, we can't go back to our childhood to learn English, but we can learn from kids. {#blank#}1{#/blank#}

Play to learn.

Kids learn when they play games. You can't just learn English by reading a textbook or you will lose attention. You can learn English through imaginative play (想象游戏) like a kid. You can imagine that you're ordering a meal in London. {#blank#}2{#/blank#}

Learn in an English-speaking environment.

{#blank#}4{#/blank#}

One of the reasons kids learn so well is that they have no fear! Don't worry about making mistakes-just keep practicing until you get things right! {#blank#}5{#/blank#} But if you stick to it, and you will achieve your goals. Trust me-it's worth it!

A. It's important to retell what you read.

B. Don't be afraid of making mistakes.

C. Learning a language takes time and effort.

D. Don't choose a book that is too easy or too difficult.

E. Here are some advice on learning English like a kid.

F. If you don't have such friends, go to an English corner.

G. Think about how you talk to others and what food you would pick in English.
