Question

Now ( ) Tom's turn to recite the text. A.there is B. is going C.has come D.comes.

选哪个答案并给出理由

Answer 1

D. comes.
倒装句。Now Tom's turn comes to recite the text.
there is: 有，那儿有
is going: 将要（做...）
has come: 是已经完成时态

追问

有now ,为什么不能选B

追答

B.is going, 恢复原句：Now Tom's turn is going to receite the text. 都连不通顺
be going to不是表示正在进行时，是将来时态，跟will的意思差不多
例： We are going to have a meeting this afternoon,
这句话的意思跟We will have a meeting this afternoon是一样的
