1. I will never forget the ten years ___ we both spent in the little village.

A. when B. during which C. which D. in which

【答案】C。该题是定语从句。关系代词which在定语从句中做动词spent 的宾语。从句还原一下：we both spent ten years in the little village.

2. My vacation begins next Tuesday, ___ I will leave for Florida.

A. which B. that C. while D. when

【答案】D 从句意上可以判断该句后半部分是限定Tuesday 的定语从句，所以C项可以排除;在该定语从句中，先行词Tuesday在从句中作状语，应该是on Tuesday, 故引导定语从句可用on which或when。

3. Before joining the army, he spent a lot of time in the village ___ he belonged.

A. to which B. which C. to where D. at which

【答案】A。固定搭配belong to ：属于。因此选 to which。Where是连接副词不加介词。

5. The moon is a world that is completely still and utter silence prevails.

A. that B. where C. which D. whenever

【答案】B 这句话中world 带来两个定语从句，一是that is completely still“完全静止”，二是where utter silence prevails,“完全沉寂”，其中utter silence “完全的沉寂”，prevail v.“盛行，遍及”;这里必须用where 引导从句，是因为world 这个先行词在--utter silence prevails 中充当地点状语，where=in which,“在月球上';全句意为“月球是一个完全静止，完全沉寂的世界”。
