I don't know ____ Mike will come to see me tomorrow.A that B

題目：

I don't know ____ Mike will come to see me tomorrow.A that B when C if D what 選哪個?爲什麼?

解答：

C.
I don't know if(=whether) Mike will come to see me tomorrow.
我不知道Mike明天是否來看我.
如果選A,則don『t 須改爲didn『t；如果選B,則when改爲What time；如果D,句子後面要加for.
希望對你有所幫助.
再問： 選A 爲什麼don't要改爲didn't？ B 爲什麼when要改爲What time?
再答： 現在不知道，怎麼有後面的事情？ 已經有了tomorrow，所以具體的幾點鐘用What time提問。
