考题1：[常州] — Why didn’t you open the door for me, Jim
—I ______ clothes in the bathroom. I didn’t hear the knock.
A. am washing B. have washed
C. was washing D. washed
C
【点拨】考查动词时态。句意为“—Jim, 你为什么不给我开门？—我正在卫生间洗衣服，我没有听见敲门声”。根据上下文语境可知，此处强调在过去的某个时间正在发生的动作，用过去进行时，结构为“was/were + 动词的现在分词”。

成千上万的人正在山上种树。
two thousand 两千

考题2：[滨州] —China is a great country with a history of about five _____ years.
—Yes. And _____ of foreigners come to visit it every year.
A. thousand; thousand B. thousands; thousands
C. thousand; thousands D. thousands; thousand
【点拨】考查数词的用法。thousand 千，前面要用具体数字，即“数字+thousand + 名词复数”；thousands of + 名词复数，意为“成千上万的……”，表示笼统数字，前面不加具体数字。
