问题描述：
用括号内的正确形式填空（5个）
Since I ____(have) enough time,I ____(feel) at ease.
“I'm sorry.I ___(think) I ___(do)it before I ___(come)out of the door.”
请解释为什么这么填,
答
Since I have enough time, I am feeling at ease.
I'm sorry! I thought I had done it before I came out of the door.
答
Since I have enough time, I feel at ease.
由于我有足够时间,我很放松.
我感到怎样只要用一般时,如I feel happy,然后前面是时间状语从句,表示现在,故都用一般现在时
I'm sorry! I think I had done it before I came out of the door.
很抱歉,我想我出门之前已经做了.
填think是现在在想,一般都是用I think,不用过去式或其他,后面出门是过去做的动作,用一般过去时,然后do it是过去的过去,用过去完成时
