简单的高中英语语法题求助
1.Helen was there too. She _____(wear) a beautiful dress.
答案填was wearing,请问为什么要用过去进行时,过去进行时在词句里边的判断标志是什么,用一般过去时可以吗?
2.If you ____ to the post office this afternoon, I ____ go with you.
A. will go, shall B. go, will C. are going, would D.are, shall
选哪一个,都用的是什么时态,为什么要用该时态?
答
1.过去进行时不仅可以表示过去某个时刻正在进行的动作,还可以表示过去某段短暂的时间内持续的状态.这里意思是当时Helen正穿着一件漂亮的连衣裙.
2.选B.这里包含了一个条件状语从句.主句是I will go with you.主句用一般将来时,从句要用一般现在时是表将来,所以是 if you go to the post office this afternoon.
