课后巩固提升
Ⅰ.1.C at the beginning of…为固定搭配，意为“在……之初”。
2．C 句意：许多动物因为严重的污染处于危险中。in danger意为“处于危险状态”，符合语境。
3．C
4．D 考查名词作定语和主谓一致。第一个空作定语修饰doctors。man，woman等名词作定语时，要与后面的名词在数上保持一致，可首先排除A、C两项；由疑问词how many可知答语应为医生的数量，“the number of＋可数名词的复数”作主语时，谓语动词用单数形式。故选D。
5．D
Ⅱ.[主旨大意] 这篇短文讲述的是现在老虎的数量急剧下降，如果再不采取措施，老虎就要灭绝了。中国和其他12个国家参加了野生动物基金会的一个项目，拯救老虎，也要拯救老虎的食物，如鹿和野猪等。
1．B 2.C
3．A 句意：在过去的70年里，东北虎的数量从300多只下降到了不足22只。根据语境可知，东北虎的数量比过去少了。故选A。
4．D 考查介词短语。句意：东北虎处在完全灭绝的危险中。in need of意为“需要”；in the middle of意为“在……中间”；in front of意为“在……前面”；in danger of意为“处在……的危险中”。根据句意可知，由于东北虎的数量减少了，东北虎处在灭绝的危险中。故选D。
5．A
6．B
7．A 考查动词短语。句意：它的目的是拯救野生的老虎，结束老虎被猎杀的现状。根据句意可知，这句话说的是野生动物基金会开始这个项目的目的，故选A。
8．C 9.D
10．C 考查动词。根据文意可知，老虎以鹿和野猪为食，所以拯救老虎也就要拯救这些老虎的食物，不然老虎会被饿死了。故选C。
