强调句与非强调句最大的区分就是是否可回复原来的句来判断 即把It is\was ...that...去掉,如果剩下仍能组成一个完整的句子,就是强调句型 否则就不是! 例如: It is there that accidents often happen.---Accidents often happen there .(那儿经常发生事故 ) 这就是强调句型 被强调的成分是地点状语,把It is...that... 去掉,还原成原来的非强调句型。又例如It is clear that not all boys like football. ( 很明显,并不是所有的男孩儿都喜欢足球)去掉It is...that... 后的句子是Clear not all boys like football. 这显然不是一个完整的句型 因此不是强调句型! 强调句型除了It is ...that...这种形式外,还有it might be...that... \ it must have been ...that ...表示强调句型! 有时候not...until...也可表示强调句型 如It was until ten o'clock that he went to bed.( 他直到十点踩上床睡觉)
