John rescued the drowning child (at the risk of his own life)(John冒着自己生命危险救了那个溺水的孩子。)此题中动词rescue变成了过去式,而要填写部分的正确答案risk则是原型,是不是在一句话中只有一个动词需要变化来满足主谓一致这个原则?但是在以下的这两个题中,却不是这样
1.The university authorities did not approve the regulation,
Nor did they explain why(校方没有批准这个条例,也没有解释为什么)。
2. Although he was interested in philosophy,(his father persuaded him into)(尽管他对哲学感兴趣,但是他的父亲说服他以法律作为专业。)majoring in law.
第一个句子do变成了did,而第二个persuade也变成了过去时这是为什么呢?
针对你说的“时态一致”这一原则,是不是也要把所有的动词都变一致了
追答这里的时态一致 只是 一种现象, 并不是原则. 主谓一致是原则
并不是 都要求 时态一致 而是要求时态的用法 要符合逻辑
该用什么时态 就用什么时态
如 when he came in, i was reading.
he said that he would do it .
he said that he had done it.
he said that he was doing it.
he was a student five years ago and now is a teacher.
