我有2个问题:1)正确选项E,(E) to suggest that the elephant is descended from an aquatic animal and t ...
我觉得这才是这道题目的关键。整个后面的句子用的是suggest that someone (should) do 的句型。所以排除其他suggest that someone has done的选项。
gapping是英语写作中的一种语法,省略连词连接的并列分句中的重复动词。
比如, Some ate bread, and others (ate) rice.
Fred likes to pet the cat, and Sally (likes to pet the) dog.
is作为这里的重复动词被省略掉了。希望研究过这道题的出来指正。
