初三英語題請幫我解釋一下
Let 's hurry ,there are only 2 mintues___
A leave B to leave C left D leaving
Our teacher did what she could ___us with English
A help B helped C helping D to help
He often says that he ___(buy) a new house for his parentsif he has enough money

解答：

C,There be ...left.是個固定句型,翻譯爲還剩.
D,兩個動詞之間如果沒有固定搭配的話,都用to隔開.而這裡what she could是個定語從句,不要被迷惑了.
will buy 因爲if從句中用現在時表示將來時,所以主句要用到將來時,即will buy
