参考答案
一、
1. in case
【解析】考查状语从句。结合句意表示“以防”可知应用in case，引导目的状语从句。故填in case。
2. no matter what
【解析】考查让步状语从句。根据提示可知，设空处应填no matter what“无论什么”引导让步状语从句，what作say的宾语。故填no；matter；what。
3. Whatever happens
【解析】考查让步状语从句。根据汉语提示，“不管发生什么事”可用让步状语从句结构，“无论何事”可译为whatever，在句中作主语，“发生”可译为happen，根据其后主句用一般将来时，故从句中用一般现在时，所以应填Whatever happens。
4. No matter how/However carry us through/help us get through
【解析】考查状语从句、固定短语和动词时态。表示“无论怎样”应用no matter how/however引导让步状语从句；表示“帮助我们度过难关”应用carry us through/help us get through；will后面需加动词原形，构成一般将来时。故填①No matter how/However；②carry us through/help us get through。
5. before is
【解析】考查连词和时态。根据句意“还要多久才……”，可知第一个空用连词before连接前后两句话；第二个空是before引导时间状语从句的谓语，且用到句型it be +adj. + to do sth.“做某事是……”，所以此空用be的适当形式做谓语；再根据句意，描述的是从现在的角度看以后的情况，应用一般将来时，再根据时间状语从句中，从句要用一般现在时代替一般将来时，主语是it，所以第二个空填is，故 ①before；②is。
6. was that
【解析】考查状语从句和部分倒装。表示“如此……以至于……”，引导结果状语从句，应用so…that…，且so位于句首，主句中的主语和谓语需部分倒装，即将be动词、助动词或情态动词置于主语之前，此处应将be动词放到主语之前，根据后文some houses were destroyed可知为一般过去时，主语为单数名词storm，be动词用was。故填①was②that。
7. never/not controlled until found
【解析】考查固定句型、动词及连词等。根据汉语意思可知，空1处和空3处应使用never/not …until…这一固定句型，表示“直到…...才”引导时间状语从句；根据空2前的be可知，空2处应使用过去分词controlled，构成被动语态，表达“得到控制”（由于control与所修饰词cholera之间是被动关系）；根据空4前的was可知，空4处应使用find的过去分词found，构成被动语态，表达“被找到”（由于find与所修饰词cause之间是被动关系）。故空1填never/not，空2填controlled；空3填until，空4填found。
8. the scene is so attractive that it is beyond the words
【解析】考查时态和状语从句。“风景”the scene(特指)，so...that...(如此……以至于……)引导结果状语从句，“吸引人的”attractive，“无法言表”beyond the words。故填①the scene②is so attractive that it is beyond the words。
9. Each time can’t help smiling
【解析】考查固定搭配、时间状语从句和动词。根据提示可知，表示“每次”应用固定搭配each time引导时间状语从句。表示“忍不住做某事”应用固定搭配can’t help doing。表示“微笑”应用动词smile。句首首字母应大写。故填①Each time②can’t help smiling。
10. Though exercise is important it is not a good idea
【解析】考查状语从句。分析可知，句子用though引导让步状语从句，主句用it做形式主语，表示“尽管锻炼很重要”为Though exercise is important，表示“……并不好”为It is not a good idea to do sth.，表示的是一般的情况，所以要用一般现在时。故填Though exercise is important；it is not a good idea。
11. in case you need to rent a car
【解析】考查状语从句和固定短语。引导目的状语从句，表示“以防”应用in case；从句中主语为you，表示“需要做某事”短语为need to do sth.；表示“租车”短语为rent a car。故填in case you need to rent a car。
12. If it is convenient for you
【解析】考查固定搭配和条件状语从句。分析句子结构可知，空格处应填if引导的条件状语从句，且主将从现，所以应用一般现在时；it is convenient for sb.( to do sth.)表示“对某人来说（做某事）是方便的”，所以空格处应填if it is convenient for you,if放句首，首字母大写。故填If it is convenient for you。
13. the moment
【解析】考查状语从句和短语。根据中英文提示，空格前后是句子，需要加连词，the moment“一……就……”引导时间状语从句，故填the moment。
14. Even if/though
【解析】考查固定短语。根据所给汉语并分析句子可知，需要表达“即使”，是固定短语even if或even though，首字母大写，故填Even if/though。
15. When we seek to discover
【解析】考查时间状语从句。分析可知，空白处在句中为时间状语从句，表示“当……时”用when；表示“我们”用we；表示“试图发现”用seek to discover；结合we somehow bring out the best in ourselves，所以此处时态用一般现在时。故填When we seek to discover。
16. when he met
【解析】考查状语从句和时态。分析可知，空处为when引导的时间状语从句，表示“碰到”为动词meet，was表示用一般过去时。故填when he met。
17. while/ when he was working abroad
【解析】考查状语从句。分析可知，空处为when或while引导的状语从句，表示“在国外工作”为work abroad，kept表示用过去时，且表示过去一段时间持续的动作，所以用过去进行时，注意主谓一致。故填while/ when he was working abroad。
18. so that
【解析】考查结果状语从句。so that“为了”引导目的状语从句，当so that前面有“，”时，so that一般表示“以至于”，引导结果状语从句。根据语境和句意，可知这里是so that引导的结果状语从句。故填so that。
19. Although/Though/While the kitchen is small although/though it is small Small as/though the kitchen is
【解析】考查让步状语从句。分析可知，第一空，“这个厨房虽然小”，Although/Though/While都可以引导让步状语从句放在句首，放句首首字母大写，“房间小”为“the kitchen is small”；第二空，“The kitchen”已出现过，所以后半句主语用“it”代替，且用although/though引导后半句的从句；第三空，表语+ although/though+主语+系动词，为although/though引导的让步状语从句的倒装。故填①Although/Though/While the kitchen is small；②although/though it is small；③Small as/though the kitchen is。
20. In order that so that/in order that in order to/so as to/to In order to/To
【解析】（1）分析句子结构，____________________ he could avoid the traffic jam, he left early.这是一个复合句，含目的状语从句，so that/in order that 引导目的状语从句，但so that引导目的状语从句时不位于句子开头，故答案为In order that。
（2）分析句子结构，He left early ___________________ he could avoid the traffic jam. 这是一个复合句，含目的状语从句，so that/in order that 引导目的状语从句。故答案为so that/in order that。
（3）分析句子结构，He left early ___________________ avoid the traffic jam.这里是不定式（短语）作目的状语，so as to do sth./in order to do sth./to do sth.故答案为in order to/so as to/to。
（4）分析句子结构，___________________ avoid the traffic jam, he left early. 这里是不定式（短语）作目的状语，so as to do sth./in order to do sth./to do sth.，其中so as to 不能位于句子开头。故答案为In order to/To。
21. as/so long as

22. each/every time I drove by
【解析】考查连词、固定搭配和时态。根据句意和句子结构，此处用each/every time“每一次”作连词，引导时间状语从句。根据主句谓语would visit以及句意，表示的是“过去常去拜访”，可知描述的是过去的事，所以从句用一般过去时，用动词短语drive by“开车路过”作从句谓语，主语是I，故填each/every time I drove by。
23. The last time I saw you
【解析】考查时间状语从句和一般过去时。分析句子，空处为“上次我见到你时”，在句中做时间状语成分；表达“上次”为短语the last time；根据the last time以及主句谓语were可知，从句也应用一般过去时，故表达“我看到你”为I saw you。故填The last time I saw you。
