因為find是在couldn't的后面.could是can的過去式,couldn't是could not的縮寫.
情態(tài)動詞后面的實義動詞要用原形.
could是過去式,在這里就表示出是過去發(fā)生的事情了.你回答的很好,再請教下,把couldn't換成doesn't可以嗎?不可以??梢园裞ouldn't換成didn't(注意過去時)
the boy looked for his toy everywhere,but he couldn't find it.
the boy looked for his toy everywhere,but he couldn't find it.
為什么是find不是found,因為前面是過去式啊looked for
為什么是find不是found,因為前面是過去式啊looked for
