五、阅读理解
Do you know why different animals or pests(昆虫)have their special colours Colours in them seem to be used mainly to protect themselves．Some birds like eating locusts(蝗虫)，but birds cannot easily catch them．Why It is because locusts change their colours together with the change of the colours of crops(庄稼)．When crops are green，locusts look green．But as the harvest(收获)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 to protect themselves．Bears，lions and other animals move quietly through forests．They cannot be easily seen by hunters．This is because they have the colours much like the trees．
Have you ever found an even more strange act A kind offish in the sea can send out a kind of very black liquid(液体)when it faces danger．While the liquid spreads over(散开)，its enemies(敌人)cannot find it．And it immediately swims away．So it has lived up to now though
it is not strong at all．

A．are small animals B．are easily found by birds
C．are dangerous to their enemies D．change their colours to protect themselves
( )2．How can pests with different colours from plants keep out of danger
A．They run away quickly． B．They have the colours much like their enemies．
C．They hide themselves by day and appear at night． D．They have to move quietly．
( )3．Bears and lions can keep safe because_________．
A．they have the colours much like the tree B．they move quietly
C．they like brown and grey colours D．they live in forests
( )4．Why can the kind offish live up to now
A．Because it is very big and strong．
B．Because the liquid it sends out can help it escape from its enemies．
C．Because the liquid it sends out can kill its enemies．
D．Because it swims faster than any other fish．
