答案： 56. the largest [解析]考查形容词的最高级。句意：撒哈拉沙漠是世界上最大的沙漠。in the world 在世界上，表示范围，在这个范围内描述撒哈拉沙漠，要用形容词最高级。large 的最高级形式是 the largest，表示“最大的”。
57. sunny [解析]考查形容词。句意：白天，撒哈拉一年四季都是阳光明媚的。“it's”是 it is 的缩写，is 是系动词，后面需要接形容词作表语；sun 是名词，意为“太阳”，其形容词形式是 sunny，表示“阳光充足的”。
58. to live [解析]考查动词不定式。句意：这是一个动植物难以生存的地方。此处用动词不定式 to live 作后置定语，修饰名词 place。
59. Don't eat [解析]考查祈使句的否定形式。句意：在沙漠里不要吃得太多，否则你会感到非常口渴。祈使句的否定形式一般是在动词原形前加 don't。→祈使句通常用来表示命令、请求、建议等。
60. feeling [解析]考查固定搭配。句意：每次吃一点可以防止你感觉太饿。stop sb from doing sth 是固定搭配，意为“阻止某人做某事”；from 是介词，后面接动词的 -ing 形式。

Isn't it amazing that so many animals do not like to stay in one place? Birds,fish and other animals move from one place to another at a certain time. 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(拥挤的).
When cold weather comes,many birds move to warmer places to find food. Some fish give birth in warm water and move to cold water to feed. The most famous migration(迁徙) is probably the migration of fish,which is called "salmon". These fish are born in fresh water but they travel many miles to salt water. There they spend their life. When it is cold,they will return to their birthplace in fresh water. Then they give birth and die. In northern Europe,there is a kind of mouse. They leave their mountain homes when they become too crowded. They move down to the low land.
Recently,scientists have studied the migration of a kind of lobster. Every year,when the season of the 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 nobody knows where they go.

答案： 61. for different reasons [解析]考查介词短语。根据上下文语境可知，许多动物在特定时间从一个地方迁徙到另一个地方是出于不同的原因。for different reasons 表示“出于不同原因”，符合语境。
62. in warm water [解析]考查介词短语。根据“give birth”及“move to cold water”可知，有些鱼在温水中分娩，所以用 in warm water。
63. spend [解析]考查动词。根据“These fish are born in fresh water but they travel many miles to salt water. There they... their life.”可知，鲑鱼在咸水中度过它们的一生。spend 有“度过”的意思，主语“they”是复数，句子时态为一般现在时，所以用动词原形 spend。
64. move [解析]考查动词。根据“when they become too crowded. They... down to the low land”可知，它们在变得过于拥挤时向低地迁移。move 有“移动，迁移”的意思，主语“They”是复数，句子时态为一般现在时，所以用动词原形 move。
65. get into a long line [解析]考查动词短语。根据“... the lobsters... and start to walk across the floor of the ocean.”以及常识可知，龙虾在迁徙时会排成一条长队。get into a long line 表示“排成一条长队”，符合语境。

68. They live on insects and plants. [解析]“它们”是 They，作主语；“以……为食”用 live on 表示，主语是复数，谓语动词用原形；“昆虫”是 insects，“植物”是 plants，用复数形式表示类别。
