紧急
The little boy is dirt from head to foot because he _____ in the mud all morning.
A.has played B.is playing C.has been playing D.was playing
是用过去完成时 还是现在完成进行时
紧急 The little boy is dirt from head to foot because he _____ in the mud all morning.A.has played B.is playing C.has been playing D.was playing 是用过去完成时 还是现在完成进行时
C 这小男孩浑身上下都脏了 因为他整个早晨都在泥土里玩.首先判断动作是一直持续的,所以用进行时,排除A 其次句子中的谓语动词是IS 所以判断时态是一般现在时,排除D .C是现在完成进行时,他这个动作持续到现在还没结束.所以选C.
C has been playing
all morning,整个早上,说明男孩从开始到现在都在泥里完,动作一直持续到现在,所以用现在完成进行时,选C
D,过去一直做某事,因为最后又all morning这个过去时间的限制。
用现在完成进行时,因为有 all morning,主句也有 is ,说明是跟现在有关的。
过去完成时是“过去的过去”,所以后面句中还会有一个过去式,如:he realized that he had left his bag at home.他发现他把包落在家了
此句用现在完成进行时
不懂可以再问。。。求采纳!
C 从过去到现在一直都在玩
