这简单,既然是倒装,那么返回成正序就能知道
谓语动词,倒装的时候就知道如何选择。
首先是倒装结构: So位于句首后跟形容词,然后是倒置的谓语动词,主语
第一句正序: The weather was so cold that we had to stay at home.
第二句正序: They ate so much that they could not move for the next hour.
其实可以发现,第一句谓语动词是be的
过去式第二句是eat的过去式,故而倒装第一句was第二句did,那么如果出现完成时或者
情态动词也是一样的,例如: 正序 They had gone so far that they could not move any more. 倒装: So far had they gone that they could not move any more. 这里是谓语动词go的完成式,但与过去式不同倒装要倒置
助动词had而不是did,故而这里有时态区分; 那么情态动词情况: 正序 The weather will be so bad that they cancel the plan. 倒装: So bad will the weather be that they cancel the plan. 和过去式一样这里预见情态动词是将情态动词倒置。
