你好,同学,很高兴回答你的问题

正确答案如下：

55. B

分数或百分数+ of + 名词/代词作主语时,谓语动词的单复数取决于这个名词,因为what引导的主语从句表示抽象概念,是不可数的,所以谓语动词用单数形式. 而A中的work应该搭配has finished,C中的articles是可数名词,D中的应该是three quarters of

38. C

as well as常用来连接两个并列的成分,作“也,还”解.它强调的是前一项,后一项只是顺便提及.因此连接并列主语时,谓语动词与前一项一致,所以本句的谓语动词与Mary一致,是单数.

39. A

the + 形容词,表示一类人,谓语动词用复数形式

40. D

all 作主语时,表示抽象概念,谓语动词用单数

34. D

当the rest,分数或百分数+ of + 名词作主语时,谓语动词与这个名词保持一致,而magazines是复数名词,而且时态是一般过去时,所以选D

35. C

sugar是不可数名词,作主语时,谓语动词用单数

37. B

the League secretary and monitor 这里是一个人,这个人的身份既是团支书又是班长,如果用were那么,应该是the League secretary and the monitor,这样就是两个人了.
