Everyone worries. But how do you deal with your worries? Whether your worries are big or small, you can take these three steps to do with your worries:
1. Try to find out what you’re worded about
Sometimes, you will know what you’re worried about. Other times, you might not. Try to find it out first; if you can’t, you can ask for help.
2. Think of ways to make it better
There is always something you can do to help you feel less worded. Sitting there worrying is no fun and it won’t solve your problem.
Grades at school are often top worries for kids. If you’re worded about grades, ask yourself these questions:
★ Why are grades important? What do grades mean to me?
★ How do I get ready for class? Do I go over my notes even when there isn’t a test?
★Do I have a good place to do my homework?
★ Have I tried different ways of studying?
If your worry is about a fight you had with a friend, you might write down all the things you could do: write a note to him or her, invite him or her to a basketball game, say sorry to him or her, etc. Once you have a list of things you could do, you can choose the one that gets your friend back.
3. Ask for help
When you’re worried, it can help to find someone to talk to. You can ask your parents, friends, or teachers for help.

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.

Trees are useful to man in three very important ways. The first important way is that they provide man with food，wood and other products. Trees provide man and animals with food to live on the earth. It’s not easy for man to live on the earth without trees.

The second important way is that trees give us shade. On a hot summer day，people are eager to（急于）have a rest under the shade of a tree after they have walked a long way. You can imagine how important the shade of a tree is to man and animals.

The third important way is that trees help to prevent droughts and floods. However，in many parts of the world，man has not realized the third important way. He has cut trees down in large numbers. In the end he finds that he has lost the best friends he once had.

1.Is it easy for man to live on the earth without trees?

2.What is the first important way that trees bring us?

3.Where are people eager to rest after they have walked a long way?

4.In the end he finds he has lost the best friends he once had. What does ‘the best friends” here mean?

?????????????????????????????????????????????????????????

In the 13^th century, the famous Italian traveler, Marco Polo, traveled a long way to China. During his stay in China, he saw many wonderful things. One of the things he discovered was that the Chinese used paper money. In Western countries, people did not use paper money until the 15^th century. However, people in China began to use paper money in the 7^th century.

A Chinese man called Cai Lun invented paper almost 2000 years ago. He made it from wood. He took the wood from trees and made it into paper. He then put these pieces of paper together and made them into a book.

Now paper still comes from trees. We use a lot of paper every day. If we keep on wasting so much paper, there will not be any trees left on the earth. If there are no trees, there will be no paper. Every day, people throw away about 2,800 tons of paper in our city. It takes 17 trees to make one ton of paper. This means that we are cutting nearly 48,000 trees every day. Since it takes more than 10 years for a tree to grow, we must start using less paper now. If we don’t, we will not give enough time to grow more trees to take the place of those we use for paper.

So how can we save paper? We can use both sides of every piece of paper, especially then we are making notes. We can choose drinks in bottles instead of those in paper packets. We can also use cotton handkerchief and not paper ones. When we go shopping, we can use fewer paper bags. If the shop assistant does give us a paper, we can save it and reuse it later.

Everyone can help to save paper. If we all think carefully, we can help protect trees. But we should do it now, before it is too late.
