找到了,是prep2上的一道题目: 129. (31451-!-item-!-188;#058&006301) Turtles, as with other reptiles, can endure long fasts because they can survive on weekly or even monthly feedings; however, when food is readily available, they may eat frequently and grow very fat. (A) as with other reptiles (B) as other reptiles are able to -->? are able to 和 do 都无法指代后面的 can. (C) as other reptiles do (D) like other reptiles ? 不能看见 like 不在句首就认为是错误的,这里的 like 前面是名词,后面紧接着的是动词,所以这里不会歧义。 (E) like other reptiles are able to do 这里如果用do 也可以平行的话,那么C应该为正确答案,因为as ... do 放在句子中间的比较结构更合适,不会产生歧义。但是正确答案却是D,说明这里不能用 do 和 can 比较对等。 -- by 会员 bobo007007 (2009/12/16 17:53:52)
我觉得你引的这道和我考的不是一个考点的感觉,我的那道是强调than的前后用can还是do |
