( )2. —Do you still remember the amount of money ________ in the bank?
—Of course. What's wrong?
A. store
B. storing
C. is stored
D. stored

2. D 【点拨】money 与 store 之间是被动关系，要用过去分词作后置定语。故选 D。

( )3. —________ is your school from your home, Gina?
—Only ten minutes' walk.
A. How long
B. How far
C. How many
D. How soon

3. B 【点拨】由答语“Only ten minutes' walk.”可知，上句询问的是距离。how long 多长，询问长度或时间段；how far 多远，询问距离；how many 多少，询问数量；how soon 多久以后，询问将来的时间。故选 B。

( )4. As a science lover, I hope I can invent a bike ________ can fly in the sky.

4. C 【点拨】句意：作为一个科学爱好者，我希望我能发明一辆能在空中飞行的自行车。句子是定语从句，先行词是 a bike，关系词在从句中作主语，用 which 引导定语从句。故选 C。

( )5. —What's the most popular form of ________ in this city?

A. environment
B. entertainment
C. experiment
D. experience

5. B 【点拨】句意：——这个城市最流行的娱乐方式是什么？——这很难说。也许是看电影。答句中“看电影”属于“娱乐(entertainment)”。故选 B。
