选择填空
　　1. I don’t think I’ll need any money but I’ll bring some ____________. 
　　A.as last　 B.in case　 C.once again 　D.in time
　　解析：答案为B。句意为“带些钱以防万一”，只能选择in case。引导的条件状语从句，后面省略了I should need it。 
　　2. The WTO can’t live up to its name _________ it doesn’t include a country that is home to one fifth of man-kind. 
　　A.as long as　 B.while　 C.if 　D.even though 
　　解析：答案为C。本题考查状语从句的用法。句意为“假如世贸组织不包括占世界人口五分之一的中国的话，那它就名不副实”。as long as语气过于强烈，while和even though不符合句意。 
　　3、Someone called me up in the middle of the night, but they hung up_________I could answer the phone. 
　　A.as 　B.since 　C.before 　D.until 
　　解析：答案为C。题意为：半夜里有人打来电话，我没来得及就挂了。but暗示在接话前就挂了。
