问题解答:

我来补答
Bob____all day.Could you speak to him now?
A.phones D.has been phoning 我选A,为错了
因为这里有个all day啊,说明Bob一直都在打电话,而且现在还在打,所以用现在完成进行时,表示过去的某一个动作对现在的影响(现在完成时),而且这个动作是一直持续的(进行时),两个综合起来就可以了;
This kind of cloth ___very well.
C.has been washed D.washes我选C,为什么错了
wash 很特殊 要用主动式表示被动式,也就是说它没有被动式的,类似的词还有 系动词 以及 sell 等等,就是几个有翻译出.起来的 都是,比如smell 闻起来 wash 洗起来 等等.
I've heard that Bob _____ back from his journey to Africa.
A has come D.had come我选D为什么错了?
因为前面是 I have heard 是现在完成时啊,所以后面也要用现在完成时 ,如果 前面是I had heard 的话 那就选D.
