Question

13．It is well-known that many animals do not stay in one place．Birds，fish and other animals move from one place to another at certain times．They move for different reasons：most of them move to find food more easily，but others move to get away from places that are too crowded．
  When cold weather comes，many birds move to warmer places to find food．Some fishes give birth in warm water and move to cold water to feed．The most famous migration is probably the migration of the fish，which is called"salmon"．This kind of fish is born in fresh water but it travels far to salt water．There it spends its life．When it is old，it returns to its birthplace in fresh water．
  In northern Europe，there is a kind of mouse．They leave their mountain homes when their homes become crowded．They move down to the low land．Sometimes they move all the way to the seaside，and many of them are killed when they fall into the sea．
  Recently，scientists have studied the migration of a kind of lobster （龍蝦）．Every year，when the season of bad weather arrives，the lobsters get into a long line and start to walk across the floor of the ocean．Nobody knows why they do this and where they go．
  So，sometimes we know why humans and animals move from one place to another，but at other times we don't．Maybe living things just like traveling．
66．What does the passage mainly talk about？（No more than 10 words）Why animals move from one place to another
67．Where does the salmon spend its life？（No more than 5 words）In salt water．
68．What's the meaning of the underlined word"migration"in paragraph 2？（No more than 10 words）Move from the birth place to another place．
69．When will the mice in northern Europe leave their mountain homes？（No more than 5 words）when their homes become crowded
70．What do you think of some animals'migration？（No more than 30 words）Nobody knows why they do this and where they go．．

Answer 1

分析 這篇短文主要給我們介紹的是很多動物在一定的時候會搬家，這里的原因很多，大多數(shù)的情況是為了找到更多的食物，還有可能是因為他們原來生活的地方太擁擠了．但是有時候科學(xué)家們也不知道它們?yōu)槭裁磿�搬家�?/p>

解答 66  Why animals move from one place to another
67  In salt water．
68  Move from the birth place to another place．
69  when their homes become crowded
70  Nobody knows why they do this and where they go．
66  Why animals move from one place to another主旨大意題．根據(jù)文章內(nèi)容可知這篇短文主要給我們介紹的是很多動物在一定的時候會搬家，這里的原因很多，
67  In salt water．細節(jié)理解題．根據(jù)文章第二段This fish is born in fresh water but it travels many miles to salt water．There it spends its life．可知，鮭魚生活在咸水了．
68  Move from the birth place to another place．詞義推測題．根據(jù)前后句子This fish is born in fresh water but it travels many miles to salt water．There it spends its life．When it is old，it will return to its birthplace in fresh water．Then it gives birth and dies．可知它們生在淡水，卻要跋涉許多英里到咸水里生活．老了再回到出生的淡水區(qū)生兒育女，然后死去．故猜測migration的意思是move，遷居、遷徙．
69  when their homes become crowded 細節(jié)題． 根據(jù)文章第三 段They leave their mountain homes when their homes become crowded． 可知當(dāng)它們的家園擁擠的時候，老鼠離開了它們的山區(qū)家園．
70  Nobody knows why they do this and where they go． 細節(jié)題． 根據(jù)文章最后一段Nobody knows why they do this and where they go．可知沒有人知道它們?yōu)槭裁催w徙和遷徙去哪里．
