3.列举项的数量与提示词数量不一致
多在列举事例的时候出现，例如such as..., include...等等，
2009.5
Cinco de Mayo, or May 5, the date of a famous military victory, is celebrated (with such an activity as )dancing, parades, musical performances, and feasts.
(A) with such an activity as
(B) with an activity such as
(C) with such activities as
(D) in such activities like
(E) in an activity like that of
解析：such as是固定搭配，排除D，后面列举了四项活动，前面却用了an activity，排除A,B,E，所以选C
2010.5
(Many of )the senator’s speeches, which were( enthusiastically received )by the large crowds (that )came to see him, addressed (an important topic), including health care and global warming.
解析：including后面列举了两个话题，和an important topic矛盾，所以选D。
这两道题关键词都在错误部分后面出现，需要尤其小心。
4. Their+名词，名词数量错误
一般来讲，their后面需要接复数名词，这也是常考的形式，例如：
2010.1
The people sitting behind me in the movie theater were talking throughout the film and would not keep their voice down even after being asked to do so.
解析：voice是个可数名词，需要改成voices
George Thornton Emmons( A was one )of a handful of ethnographers who (B committed )(C their life)( D to studying )the Tlingit culture of the Northwest Coast. (E No error).
解析：这道题来自OG。life表示生命的时候可数，表生活的时候不可数，而commit one’s life to doing根据句意表示生命，所以应该是their lives，答案C。
当然，并不是所有在their后面出现的名词都必须用复数，到底要不要加复数取决于这个名词可数还是不可数，或者这个名词能不能被共享。例如：
不可共享：their voices;their minds;their lives(生命)
可以共享：their life(生活);their independence
