问两个英语问题,不要复制答案
as the thieves were trying to get away,he drove his bus into the back of it
为什么用as 不用while
“I'm inquiring about a patient” he said 为什么用现在进行时
前面的那句,一般用while时,前面和后面都要用现在完成时.如果用while.
句子应该改为:While the thieves were trying to get away,he was driving his bus into the back of it.
第二句的话,这里的现在进行时是因为说话的人现在做的,表示当时说话的时候在做,但说话这一件事(said)是过去的事.
自己好好理解下.
