Question

请英语高手帮我做下以下几道题，用适当的形式填空

1.I__(live)here for eight years since I___(come)here in1983
2.When we___(arrive) at ghe airport,the plain___(take)off.
3.My uncle___(come)to see us. He___(arrive)here a few days ago.
4.I'm sorry,I___(think)I___(tell)you.

Answer 1

1. have lived, came
since引导的时间状语从句，从句用一般过去时，而主句用现在完成时

2. arrived, had taken
take off发生在arrive之前，所以前后用过去完成时，后者用一般过去时

3. has come, arrived
后句有明显的过去时间状语a few days ago，所以用一般过去时；
前句根据句意是已经发生的动作，所以用现在完成时

4. thought, had told
从句意可知，I是过去“以为告诉过”对方的，现在已经知道其实没有“告诉过”对方（从sorry可知），所以think用过去时thought；
而tell用过去完成时，因为它发生在thought之前。
