10、A。before表明主句谓语动词与从句谓语动词之间的先后关系，有“在以前”, “没来得及就”，“不等就”的意思3. A。unless意为“除非，若不”，相当于if not。4. D。句中where the customs are really foreign to your own 是地点状语从句，in which 用于引导定语从句，因而不选A项。5. D。句中so that（以便）引导的是目的状语从句。6. C。句中in case（以防万一） 引导的是条件状语从句。7. B。the moment （一就）引导时间状语从句，与as soon asimmediately相同。8. C。even
11、though she was an only child （尽管她是独生子女）是让步状语从句。9. B。流行音乐是我们社会的那么重要的一部分以至于已经影响了我们的语言。这说明流行音乐带来的结果，本句是结果状语从句。结果状语从句的连词有：so that，sothat，suchthat.结果状语放在主句之后。注意：在sothat，suchthat结构中一般成分齐全。这也是与as引导定语从句的区别。在soas，suchas这一结构中，as引导定语从句，在句中做成分。 10. D。本句也是让步状语从句。while有“尽管”、“虽然”之意，所以可以引导让步状语从句，这一 点容易被考生忽视。在本题中还要注
12、意 as也有“尽管”之意，也可引导让步状语从句，但要将 名词、形容词或副词等提到 as 前，若提前的是单数可数名词，要省略 a / an。 11. C。注意几个选项连接状语从句时的不同意义，so/as long as“只要”符合题意。now that“既 然”用于原因状语从句。if only常引起虚拟语气，意为“要是就好了”。every time“每 次”，引起时间状语从句。 12. B。这是一个原因状语从句。原因状语从句for表示的原因并不说明主句行为发生的直接原因，只是 提供一些有利于说明情况的补充说明, 且不可位于主句前。 13. B。考查状语从句用法。句意;哪儿的失业率高 ,哪儿的犯罪
13、就率高,那可以认为是前者导致后者的 原因。14. A。根据主从句的动词时态可知主句谓语动词的动作在从句谓语动词之前已经完成，引导词的意思 是：当的时候，选A。 15. C。因为表示“正要做某事时，突然又发生另一件事”的句型是：was /were just about to do sth. whendid或was /were just on the point of doing sth. whendid 16. C。因为notuntil“直到才”，再接before语意上不通，要用after。17. C。因为no matter后一定要接疑问词或whether。 18. C。引导状语从句时no matter how=however，其后接形容词或副词，只有C正确。19. C。unless“除非、如果不”。句意是：大多数动物与其它不同种类的动物都没有什么联系，除非 是把它们猎为食物。 20. A。句意是：虽然他认为他在帮我们做工，但事实上他是在碍事。
