这几个题都是虚拟语气的用法.第三题表示对过去的事情的虚拟,因为后面有it was never done
,主句要用would、could、should、might+have+过去分词.
第四题是也是对过去的虚拟,跟第三题一样的思路.
第五题是省略if采用倒装语序的条件句,有时可以把含有助动词、情态动词、be或have的虚拟条件句中的连词if省去,而将had ,should,were 等词提到主语之前,即用倒装结构.If he had worked harder,he would have got through the exams.==>Had he worked harder,he would have got through the exams.
