名师点评
本文讲述了人类是如何利用沙漠中的绿洲、动物，并依靠自身的努力而得以在沙漠中种植庄稼，从而生存下来。说明人定胜天的道理。
(B)1. A. and B. but C. or D. so
【解析】B。空白部分两句构成转折关系，故选择并列连词but。
(B)2. A. rain B. rains C. wind D. winds
【解析】B。沙漠中风多雨少，rain一词为不可数名词，其复数形式rains表示雨水多，故应选rain。
(D)3. A. good B. good enough C. enough good D. enough
【解析】D。这里讲沙漠中的一点点雨水，并不能满足大多数植物生长的需要，故选择enough。
(A)4. A. live B. to live C. lives D. lived
【解析】A。see sb. do sth.意为“看见某人做某事”，这里应用省去to 的动词不定式。

【解析】D。沙漠之所以出现绿洲的根本原因是有了水，故选water。
(C)6. A. say B. tell C. call D. find
【解析】C。call 在这里意为“将……称为……”为正确选项。
(B)7. A. every B. all C. a D. one
【解析】B。every, a和one 后面都应该接可数名词单数，不能放在kinds 前面。all kinds of 意为“各种各样的”。
(A)8. A. also B. too C. either D. still
【解析】A。表示“也”时，too 一般放在肯定句末，either放在否定句末，also 放在句中，在此为正确选项，而still 不合题意。

【解析】C。固定说法depend on意为“依靠”、“凭借”。
(C)10. A. a little B. few C. much D. any
【解析】C。一些动物能在沙漠中生存下来，说明了他们适应了这里雨水稀少的气候，不像其他动物那样需要太多的水，故选择much。
(D)11. A. water B. plants C. crops D. animals
【解析】D。通读本段不难发现，本段承上文接着讲述动物的用途，故选animals。

【解析】B。固定说法look for 意思为“寻找”。
(D)13. A. other B. the other C. the others D. another
