Unit 9 The memory robot
（一）用动词的正确形式填空。
1._____ you _____(pack) your bag yesterday?
2.We ______(not have) a meeting last Monday.
3.When did you get up this morning? I ______(get) up at six.
4.Who _____(come) here at seven this morning?
5.When did he buy his new watch? He ______(buy) it last month.
6.There _____(be) a telephone call just now.
答案：
1.Did...pack 2.didn't have 3.got 4.came 5.bought 6.was
说明：
第1题：句中的yesterday提示了该句的动作发生在过去，一般过去时的疑问句在主语之前加助动词did。

第2题：last night提示句子用一般过去时，注意括号中的not要求变成其否定句，在动词之前加didn't。

第3题：When did he buy his new watch?问过去的事情，自然用过去时回答。

第4、5、6题：句子的时间状语this morning， last month，just now都说明了句子要用一般过去时。注意动词的过去式的变化。
