超难英语语法（初三） 写理由
1.In the past few years there ____ great changes in my home town
A.have been B.had been C.were D.are
2.He's already back to Australia,____?
A.isn't he B.hasn't he

答

1.A ,In the past few years 意思是：在过去的几年,用于现在完成时,表示的是过去发生的动作对现在造成的影响或存在的 状态.整句的意思是：在过去的几年,我的家乡发生了很大的 变化.
2.A.句意是：他已经回澳大利亚了,不是吗?但是这里用的不是现在完成时的has,而是is的缩写.因为back是副词,不可能加在has后面构成现在完成时的.如果用has alrealy back 就错了,has 后面要加过去分词的.所以本句应该是：He is already back to Australia,isn't he?
