英语问题几只.
I——there is going to be a football match between Germany and Brazil this evening.
A was told
b have been told
为什么A不行?
2.The flowers_____sweet in the garden attract the visitors ti the beauty of nature.
A smell Bsmelling
3.The trees ____in the strom hae been moced off the road.
A being blown down B blown down
上面两个题,答案分别是B,B
可以将一些为什么?
第一个句子中不能有两个谓语动词,所以用smelling,第二个句子为什么不能用A?还有什么主动被动……老师讲的太快不清楚.
