高中英语时态题
He ___ articles for our wall-newspaper these three years,and he ____ about forty articles.
A.has been writing; has written B.has been writing; wrote
C.is writing; has been writing D.has written; has written
请说明为什么不选b过去时态,不就是过去写了40篇文章吗?
答
A 前一个强调一直在写，后一个强调写了的多少篇，wrote过去式显然不合适。
答
答案A
由these three years可知应选现在完成进行时，表示“写”从过去一直延续至今，并有可能继续下去；“写了40 篇”用现在完成时，表示到现在为止已完成的动作。
答
第一个空没有问题吧现在完成进行时.第二个空强调完成的动作对现在产生了影响,并且and连接一般用一样的时态都是现在完成时.主要是强调完成对现在强调已经完成四十篇的结果.因此A更好些.
