Do you know why different animals or pests (昆蟲) have their special colors? Colors in them can protect (保護(hù)) 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(kuò)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.
小題2:寫出①句的同義句。
They have the __________ colors _______ the trees have.

小題1:面臨  
小題1:Because they have the colors much like the trees.
小題1:盡管它不強(qiáng)壯,但它可以活到現(xiàn)在。 

小題1:根據(jù)第二段可知，蝗蟲可以隨著環(huán)境顏色的變化而改變自己的顏色。故填change their colors。 
小題1:like 在此是介詞“像”的意思。相當(dāng)于the same as...。故轉(zhuǎn)換為They have the same colors as the trees have.。
小題1:有一種魚在遇到危險(xiǎn)時(shí)能分泌一種黑色液體。故face在此是“面臨”的意思。

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.
