    Do you know why different animals or pests (昆虫) have their special colors? Colors in them can protect (保护) them.
    Some birds like eating locusts (蝗虫), 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 (庄稼).
    When crops are green, locusts look green. But as the harvest (收获) 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 (液体) when it ②faces danger. While the liquid spread (扩散) over, it can’t be found (被发现). And it immediately swims away. ③It is not strong at all, but it can live up to now.
    小题1:根据短文内容完成下列句子
    From the passage we learn that locusts ______________to protect themselves.
    小题2:写出①句的同义句。
    They have the __________ colors _______ the trees have.
    小题3:②处faces 的意思是_______________________。
    小题4: Why hunters can’t easily find the animals such as bears, lions in the forests?

    小题1:面临  
    小题1:Because they have the colors much like the trees.
    小题1:尽管它不强壮,但它可以活到现在。 

    小题1:根据第二段可知，蝗虫可以随着环境颜色的变化而改变自己的颜色。故填change their colors。 
    小题1:like 在此是介词“像”的意思。相当于the same as...。故转换为They have the same colors as the trees have.。
    小题1:有一种鱼在遇到危险时能分泌一种黑色液体。故face在此是“面临”的意思。  
    小题1:根据第三段最后一句可知，猎人不易发现猎物是因为它们有着与树木相似的颜色。故填Because they have the colors much like the trees.。
    小题1:not at all“一点也不”；up to“直到”。故句子翻译为“尽管它不强壮，但它可以活到现在。”。

    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.
