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, 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 colouring 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 trees.
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 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.

阅读理解
You will have a lot of reading to do in this grade this year.You can do more of it in less time if you learn to read rapidly.
Perhaps you have been told about some habits (习惯) which keep a person from reading fast and have been strongly asked to break those habits which you might have.
Do you still have any of these bad habits?Check yourself by answering“yes”or“no”to these questions.
(1) Do you move your lips (嘴唇) when reading silently?
(2) Do you point to words with your finger as you read?
(3)Do you move your head from side to side as you read?
(4)Do you read one word at a time?
If you answer“yes”to any of these questions,start at once to break the habit.If you move your tips,hold your fingers over them,or hold a piece of paper be-tween your lips while you are reading.Then if your lips move,your will know it and can stop them.
If you point to words,hold the two sides of your book,one side with your left hand,the other side with your right hand.Then you won't have a free finger to use in pointing while reading.If you move your head,place your chin (下巴) in one hand and hold your head still (静止不动的).
If you read no more than one or two or three words at a time,you need to work very hard in learning to take in (吸收) more words at each glance (一瞥) as your eyes travel across the lines of words.
Even if you do rather fast now,you can learn to read even faster.As you probably have been told,the secret of fast reading is to take in whole groups of words as each glance.Read in through groups and force (迫使) your eyes along the lines of words as fast as you can to make them go.Anyone who practices doing these things will he able to read faster.
