题目

never before in my life _ a more beautiful place than hangzhou.A.i have been to
never before in my life _ a more beautiful place than hangzhou.
A.i have been to
B.have been to
C.i went to
D.Did i go to
前面是否定词所以用部分倒装这个我知道,可是为什么不选C.
过去将来式
还有过去分词作定语表示被动 那么如何与被动语态分开
好像是过去分词是非谓语动词,句子里面有谓语动词的就用过去分词吧
那么这个句子 the students were divided into several groups to discuss the topic
这个句子也有谓语动词discuss啊 为什么也用被动时态.

答案

1.首先这句话是“never”开头,你要记住否定式开头要的话句子要用倒装结构,由此排除A、C,另外never before 暗示是现在完成时,所以是have I been to
2.关于过去分词和被动语态的区分,如果有be动词的话,也就是am,is ．are及他们的过去式,有的话就是被动语态,没有的话过去分词就是做定于的,比如“a folded chair”和“the chair is folded．”
3.the students were divided into several groups to discuss the topic
首先看一下这个句子的结构,你要记住一句话只能有一个谓语动词,请注意我说的是谓语动词,就是这个动词是做谓语的,这句话中,谓语动词是were,它被用在了被动语态中,组成词组"were divided into",所以后面的discuss 就不能用原形了,而要用不定式to discuss.
综上,你要加强的语法点是：倒装句型和非谓语
