　　答案解析

　　1. C。even if=even though,引导的让步状语从句，意为“即使, 尽管”，符合题意。

　　2. D。本题考查before引导的时间状语从句，意为“在……之前”。句意为“他来不及冲进去救他的孩子，屋顶就塌了”。

　　3. C。When it comes to. . . 是一固定句型，意为“当谈到……时，涉及”。句意为“做作业是提高考分的一个可靠方法，这在涉及到课堂测验时尤其正确”

　　4. B。该题考查where引导的地点状语从句，表示“在…地方”。句意为“我一直把照片放在我每天都能看到的地方，因为它总使我回想起大学里的日子”。

　　5. B。so long as=so long as, 意为“只要”，表示条件。句意为“只要你答应归还，你就可以把这书借走”。

　　6. D。本题考查as引导的时间状语从句，表示事物的进展，意为“随着”。句意为“那人年纪越来越大，除了园艺外其他都不感兴趣”。

　　7. A。once引导的让步状语从句，意为“一旦”。句意为“一旦明白了这条规则，就再也没有困难了”。

　　8. B。no sooner…than意为“刚…就”，相当于as soon as. 句意为“我刚走回厨房,门铃又响了,响得足以把死人吵醒”。类似用法还有hardly / scarcely…when.。

　　9. A。本题考查because引导的原因状语从句及与for的区别。for不能跟not...but这一结构连用，句意为“我批评他不是因为我恨他而是因为我爱他”。

　　10. C。unless引导的条件状语从句。句意为“他如果不努力学习, 就永远不能考及格”。

　　11. B。so that引导目的状语从句。句意为“她拼命干一边能在他回来时把一切都准备好”。

　　12. D。until引导的时间状语从句。句意为“他一直等到火山平息下来,两天后他才得以重回火山上”。

　　13. C。此题很容易错选B。误认为是not…until句型。实际上只要抓住your work is being done. 这一提示就找到了答题的关键。

　　14. D。本题考查until引导的时间状语从句，意为“到. . . 为止, 在. . . 以前”。

　　15. A。名词短语the moment用作连词，相当于as soon as,引导时间状语从句。 意为“一……就”。类似的短语或词还有the minute, the instance, directly, immediately等。
