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 not only man with food, but also many animals with food. Without trees many animals could not live on the earth. It’s not easy for man to live on the earth, either.
The second important way is that trees give us shade. On a hot summer day, people are eager(渴望)to 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 to animals.
The third important way is that trees help to prevent drought and foods. 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 had.

Do you know why different animals or pests (昆蟲) have their special colors? Colors in them can protect (保護) them.
Some birds like eating locusts (蝗蟲), but birds can’t easily catch them. Why? It’s because locusts change their colors together with the change of the colors of the crops (莊稼).
When crops are green, locusts look green. But as the harvest (收獲) time comes, locusts change to the same color as crops have.
If you study the animal life, you’ll find the use of coloring is to protect themselves. Bears, lions and other animals move quietly through forests. Hunters can’t find them easily. This is because ①they have the colors much like the trees.
A kind of fish in the sea can send out a kind of black liquid (液體) when it ②faces danger. While the liquid spread (擴散) over, it can’t be found (被發(fā)現(xiàn)). And it immediately swims away. ③It is not strong at all, but it can live up to now.

From the passage we learn that locusts ______________to protect themselves.

They have the __________ colors _______ the trees have.

Growing up on her own

WORLD No 2 tennis player Jelena Jankovic from Serbia (塞爾維亞) has won her second title of the year. She became champion of the China Open on September 28.
Jankovic first practiced tennis when she was nine years old. After six months Jankovic played her first match.
It was the national championship for kids up to 10 years old. She came to the semi-finals (半決賽).
When she was 11, she won a national championship for girls up to 12 years old. In order to continue her career, Jelena left Serbia and went to the United States.
At that time, she didn’t speak any English. And her family did not come with her. It was a hard time.
“I did not know what I needed to do when I was going to school. I could not do my homework. When you have a difficulty, there is nobody to help you. So, you learn it the hard way,” Jelena said.
However, it was a good learning experience for Jelena. “It makes me more independent (獨立的) and stronger as a person. I know how to do everything by myself so I don’t have to depend on (依賴) my parents or somebody else to do it for me,” she said.
In the US, Jelena received better conditions for practice and development of her game. In 2000, she became a professional (職業(yè)選手) and has been shining on the tennis court ever since.
根據(jù)上面短文的內(nèi)容回答問題    
1. Where is Jelena Jankovic from?
2. What is Jelena Jankovic’s job?
3. Why did she leave for the United States?
4. When did she become a professional?
5. What do you think of her hard time in the United States?
