强调句20.It was ____that caused him to serve dinner an hour later than usual.
A.we being late
B.our being late
C.we were too late
D.because we were late
why
强调句20.It was ____that caused him to serve dinner an hour later than usual.A.we being lateB.our being lateC.we were too lateD.because we were latewhy
强调句的it is 后要是一个短语,不能是一个句子.
A.we being late 不是一个有效的短语,
B.our being late 是动名词的复合结构,相当于一个名词,符合要求.
C.we were too late 是一个句子,不符合要求
D.because we were late 也是一个句子,不符合要求
was 后跟宾语应是名词或名词性从句
so
it is(was) that出现时,先要考虑是否是强调句,强调句中it is(was) that省略之后仍是完整的句子,B选项是动名词短语可以作主语,而其他的不可作主语,故答案选B
