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?

答案

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.
