答案：

1．答案：A
【参考译文】她按照经理的指示办事。
【试题分析】本题考查关系词的用法。
【详细解答】 as可做关系词引导方式状语从句；until和when都引导时间状语从句；though引导让步状语从句。根据句意，此处应用关系词引导方式状语从句，故选项A为正确答案。

2．答案：C
【参考译文】那对双胞胎都没被捕，因为我昨晚在一个晚会上看见了他俩。
【试题分析】本题考查代词的用法。
【详细解答】根据句意，此处指那对双胞胎都没被捕，所以可排除B、D项； none表示"没有(人或物)"，后常跟of短语，作主语时谓语动词可用单数或复数形式；neither表示"(二者之中)哪个也不"，后跟of短语，作主语时谓语动词须用单数形式。此题中指双胞胎两个人中哪个也没被捕，故选项C为正确答案。

3．答案：B
【参考译文】一段时间以来，世界各国首脑一直在不断地指出达成武器裁减协议的必要性。
【试题分析】本题为语法题，考查对时态的掌握。
详细解答】由句中时间状语"for some time now"可知，这里要用现在完成时；选项B为现在完成进行时，表示动作从过去某一时间一直持续到现在，故为正确答案。

4．答案：B
【参考译文】你是否经历过明知对方是正确的却不愿意同意其观点的场合呢？
【试题分析】本题考查关系词的用法。
【详细解答】本句是一个同位语从句，先行词是situation，从句是对其内容的解释，此同位语从句只能用that引导。

5．答案：A
【参考译文】我们刚在套房里装了两台空调，明年夏天的日子会大不一样。
【试题分析】本题考查关系代词的用法。
【详细解答】这是一个非限制性定语从句，此处缺少一个关系代词；由于该非限制性定语从句先行词是air-conditioners，所以关系代词应用which。

6．答案：C
【参考译文】据说艾滋病在过去的几年中对于那个地区的男女来说是头号杀手。
【试题分析】本题考查对非谓语动词的掌握。
【详细解答】由句中的时间状语"over the past few years"可知动作发生在谓语动作之前，故应用不定式的完成式作宾语。

7．答案：D
【参考译文】她设法从工资中攒了如此少的钱来帮助她的哥哥。
【试题分析】本题考查副词的用法。

【试题分析】本题考查连词的用法。
【详细解答】在这四个选项中，只有as引导的让步状语从句可用倒装，故为正确答案。

9.答案：C
【参考译文】该实验还需要投入更多资金。
【试题分析】本题为语法题，考查more...than这一结构的用法。
【详细解答】在more...than这一结构中，than后面应跟动词原形，又因为主语是the experiment，所以谓语用单数，故选项C为正确答案。

10. 答案：A
【参考译文】要不是摔断了腿，她可能会通过考试的。
【试题分析】本题为语法题，考查对考虚拟语气的掌握。
