答案:

1.[答案] B

[解析] 下划线处表示 “正在这时，突然……”，四个选项中只有when可以表示此含义。

2.[答案] C

[解析] 下划线处表示 “正在这时，突然……”，四个选项中只有when可以表示此含义。

3.[答案] A

[解析] 题意为“当我们正在湖里游泳的时候突然暴风雨开始了”，表示主句的动作处于从句的动作突然发生时应采用when(while不适合用于这样的语境)，when表示“当……的时候”受限制条件最少。

4.[答案] B

[解析] 主句中“get me some stamps”的动作发生在时间状语从句“you’re there”的过程之中，因此应选while表示这一时间关系(属于while引导时间状语从句的两大基本用法之一)。因此B选项是最佳选项。

注意：如果主句的动作发生于表示“;当……时”的时间状语从句中的动作的进行过程中，从句常用进行时。例如：The landlady suspected that someone must have broken into the house when/while/as she was watching TV show. 女房东怀疑在她看电视时曾有人闯入屋里。// When/While/As Tom was reading, Jim was arrested. 在汤姆看书的时候，吉姆被逮捕了。

5.[答案] C

[解析] 根据题干句子含义，事故发生于当我沿街行驶、寻找停车之处的时候;从句的动作发生在主句动作的过程中。主句的谓语动词go表示非延续性的动作，可以持续进行，应选用过去进行时的形式，从句的谓语动词为非延续性动词，应以一般过去时的形式表结果。

6.[答案] B

[解析] 表示“他康复并返回工作岗位之前至少还需要三个月”，下划线处应选用before。

7.[答案] D

[解析] 题干意为：过了一段时间我们才意识到真相。下划线处应填入表示“在……之前”的连词。

8.[答案] A

[解析] 题干的句子可以直译为：“在我们一生中，学到某个教训是困难的，直到我们真正经历了这个教训为止。”

9.[答案] D

[解析] 讲故事的人应该始终抓住听众的好奇心，本题应选用表示“到……为止”(跟主句里肯定形式的表延续性动作的谓语动词连用)的until 表示这一时间关系。

10.[答案] C

[解析] “I don’t really work here”表明说话人只是临时前来帮忙，“until the new secretary arrives”表明说话人，工作到新秘书就任为止，本题应选用表示“到……为止”(跟主句里肯定形式的表延续性动作的谓语动词连用)的until表示这一时间关系。

11.[答案] C

[解析] 题干中的since表示“自从……以来”，主句中的谓语动词应该表示从他们在上海相遇至今的持续性的动作，因此下划线处应填入可以表示持续性状态的have been(其他选项中的made、become、turned所表示的动作都不能延续，意味着结果)。

12.[答案] D

[解析] since表示“自从……以来”。
