Do you know why different animals or pests have their special colours? Colours in them seem to be used mainly to protect themselves.

Some birds like eating locusts(蚱蜢),but birds cannot easily catch them. Why? It is because locusts change their colours together with the change of the colours of crops. When crops are green, locusts look green. But as the harvest time comes, locusts change to the same brown colour as crops have. Some other pests with different colours from plants are easily found and eaten by others. So they have to hide themselves for lives and appear only at night.

If you study the animal life, you’ll find the main use of colours is protecting themselves. bears, lions and other animals move quietly through forests. They cannot be seen by hunters. This is because they have the colours much like the tree.

Have you ever noticed an even more strange act? A kind of fish in the sea can send out a kind of very black liquid(液体) when it faces danger. While the liquid spread over, the enemies cannot find it. And it immediately swims away. So it has lived up to now though it isn’t strong at all.

1.How can pests with different colours from plants keep out of danger?

A. They run away quickly.

B. Their colours are much like their enemies.

C. They hide themselves in the day and appear at night.

D. They have to move quietly.

2.The kind of fish can live up to now because .

A. it is very big and strong

B. the liquid it sends out can help it escape (逃脱) from its enemies

C. the liquid it sends out can kill its enemies

D. it swims faster than any other fish

3. Which is the best title for this passage?

A. The Change of Colours for Animals and Pests.

B. Colours of Different Animals and Pests.

C. The Main Use of Colours for Animals and Pests.

D. Some Animals and Pests.

Four ways to have a good school life

Your schooldays should be some of the best and happiest days of your life. How can you get the most from them, and be sure you do not waste (浪费) this great chance to learn?

Be active(积极的) at school Don’t say things are difficult or boring. Take interest in school life and your school subjects. Join lots of activities. Put up your hands quickly in class. Go around the school with a big smile. If you are not working, you are wasting your time at school. Teachers cannot make everything enjoyable(令人愉快的).

Keep fit If you don’t eat a good breakfast, you will be thinking about food in class. If you go to bed late and don’t have enough sleep, you will be sleepy in class. Play enough sports every day in order to keep your body strong.

Face the problem Do not say you will do things tomorrow. If you get behind the class, it is very difficult to get back in front. You cannot finish the race if you rest all the time. Everyone fails some exams, loses some matches and has bad days. Don’t make small problems very big and important. Don’t forget to ask for help. You are young, and no one thinks you must de everything quite well!

Spend the weekends Don’t waste time lying in bed on Saturday or Sunday morning. Go and play sports, get together with friends in the park to relax, or learn to play the piano. If you don’t want to go out, there are also a lot of things to do. You may read a book, practice English or help Mum with housework.

Follow our advice, and have a happy school life!
