9、语从句的连接词，做状语从句类的题目，需要理解句意，然后判断前后分句的逻辑关系，进而选出相应的连接词。where在此引导地点状语从句，类似的句子有：Where there is a will, there is a way.有志者事竟成。9. -Do you think we can get there on time?- Yes, _ the car doesnt break down.A. even if B. in case C. so long as D. only if【答案解析】 C【详解】考查条件状语从句。句意：你认为我们能按时到达那里吗?是的，只要汽车不抛锚就行。A. even

11、。设空所在句子“_we should expect gratitude”描述的是主句“we often find the opposite”发生的地点，所以是地点状语从句；地点状语从句的引导词为where。故选D项。【点睛】地点状语从句容易和定语从句混淆，要区别好两种从句一定要结合定义去理解。Where引导的定语从句前面有表示地点的先行词，而where引导的地点状语从句前面并没有表示地点的先行词。如A tall building was put up at the place where there used to be a desert.这个句子就是定语从句，因为有先行词place在从句中充

14、med in large quantities.A. because B. unless C. although D. until【答案解析】 C【详解】考查状语从句。句意：酒精被归类为镇静剂，尽管它是合法的，但如果大量饮用会损害肝脏。A. because因为；B. unless除非；C. although尽管；D. until直到为止。根据空格后文“it is legal, it can damage the liver if consumed in large quantities.”（ 它是合法的，如果大量饮用会损害肝脏。）可知，有转折关系，“although”（尽管）符合句意，故选C。

17、然；B. in case以防万一；C. even if即使，尽管；D. as if似乎，好像。前一句说“they lost some pigs”，后一句说“they are still earning much more than before”，前后两个句子之间语义转折，因此用even if引导让步状语从句。故选C项。15.

18、 D【详解】考查状语从句的连词。句意：医生给了病人他的手机号码，以防病人需要医疗援助。A. if only要是多好；B. as if好像，仿佛；C. even though即使，尽管；D. in case以备，以防，免得。故选D符合语境。16.
