选哪个答案并给出理由

优质解答

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
