一道白勇语法，优于问题》

17.Although the coordination of monetary policy can help facilitate the orderly financing of existing imbalances, it is unlikely that its effect on their size is significant in the absence of an appropriate fiscal adjustment.
(A) it is unlikely that its effect on their size is significant
(B) it is unlikely that the size of their effect would be significant
(C) affecting their sizes are not likely to be significant
(D) the significance of their effect on its size is unlikely
(E) its effect on their size is not likely to be significant

这道题的答案是E。我想问问为什么A不对啊，是不是说 sth  is likely  to do ....优于  it is likely  that  ....结构啊？

呵呵,是搞错了...晕死...明明自己指的地方A和E都有的...对不起"观众"了`

这里考察的应该不是这个问题.  对比A和E,表达相同的意思,虽然it is unlikely that这个用法没有错,但是和E 比起来,不免有"不够简洁"的嫌疑

看看NN怎么说吧~

我認為A不好的關鍵在於太囉唆，相較之下，E比A直接而簡潔。

語法上，be likely to 與 it's likely that 都成立。
