Lead(铅)is very harmful for the human body and it is used in most hair dyes. Since the base of hair is the scalp(头皮)，you may have allergic reaction(过敏反应).
While dyeing your hair it is important to take some safety measures. You can follow them even when you are applying(涂) dye on your hair at home.
• It is better to apply hair dye for a few minutes. If you leave your hair with dye, longer than the necessary time，then you may get some skin problems.
• Don"t forget to wear gloves while applying dye on the hair. This will protect the skin of your
hands.
• After applying hair dye it is important to wash your hair with water.
• Hair dyes are made of chemicals. If you mix different hair dyes ,there may be chemical reaction. So, It is not a good idea to mix different hair dyes at the same time.
• Finally all the bags of hair dyes carry the directions(说明书 ) Try to follow them very carefully. This will lower the chance of allergic reaction.

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 those small parts 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 do not 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 and find out more information, we will use it in the wrong way, just to make people more attractive, or stop sick people getting jobs.

Beginning in the middle of the 20th century, a few people were worried about polluting the earth’s water and air, but most people did not change their way of life. Instead, they continued to pour(倒) dangerous chemical(化学物品) and other waste into lakes and seas, to drive more and more cars and trucks, and to cut down trees.
By the year 2200, the earth’s water was completely polluted. People could no longer drink water, and they had to use other types of liquids(液体). Scientists said that in the future there might be too many people on the earth. But not enough was done.
So by the year 2300, there were so many people that food became scarce. There was no water to grow food and all of the fish in lakes and seas died because of pollution. Terrible wars broke out between the rich and the poor. Scientists were working very hard to find another planet in space where humans could live.
By the year 2400, the air was too polluted for humans to breathe. So we had to leave the earth. But only the rich were able to leave. Where did we go? Nowhere. And everywhere. You see scientists did not find another safe planet, so now we must travel around the universe in our space ships. We are still looking for a place to call our home.
So it is up to you to change history. There is still hope. You must change your lifestyle now, before it is too late.
小题1:Which problem is NOT talked about in Paragraph 2?
| A．Water | B．Air | C．Lifestyle | D．Food |
| A．昂贵的 | B．充足的 | C．缺乏的 | D．特殊的 |
| A．Only a few people changed their lifestyle in the 20th century. |
| B．There was no clean water for people to drink by the year 2200. |
| C．All the fish died because of the pollution by the year 2300. |
| D．We found a new home in another planet by the year 2400. |
| A．Stop polluting | B．Change or leave |
| C．Look for new home | D．Return to the earth |
First, I think an interest in English is very important. When I was in Grade One, we had a new subject -English. It was fresh for me. I was interested in it, so I worked hard at it. Soon we had an English exam and I got a very good mark. How happy I was! After that, I learned English harder and harder. Our English teacher often teaches us English songs, the songs sound nice. I often think how interesting English is!
Second, I think English is a foreign language. I should learn it well in the following ways: Listen to the teacher carefully, speak bravely, read aloud and have a good vocabulary. Then practice again and again, never be tired. And I also have a good habit: Asking whenever I have a question, I must make it clear by asking our English teacher. How happy I am when I understand!
Besides this, I often read English stories, jokes and easy novels. From these I know English is not only interesting, but also useful. They help me understand a lot of things. So to do more reading is an important way to learn English well.
And I also do some exercises from our class magazines, and I often write English diaries. English has become a close friend of mine.
Now I have learned English for more than two years. I always keep the first position in our school. From these words, I hope every student can learn English well.
