It is not immediately clear ______ the financial crisis will
題目:
It is not immediately clear ______ the financial crisis will soon be over.
A.since B.what C.when D.whether
爲什麼D不行?
解答:
答案肯定是D
如果一定要選擇C爲答案,你必須去掉SOON,因爲soon與when衝突了.也就是說,有了soon就不能用when.沒有soon的話,答案是whether或者when.
再問: 如果去掉soon,是不是意味著 C、D都可以選了?
再答: 沒有soon的話,答案是whether或者when。
