　　3、Why are you always making the same mistake? Think of _____ I told you.

　　A. that　　B. when　　C. how　　D. what

　参考答案&解析：

　　1、A　not wanting 等于who do not want. 故答案为A。

　　2、C　many a merry night= a great many /plenty of merry nights . many a 虽然表示复数意义，但后面跟单数名词。故答案为C。

　　3、D　of后面是介词宾语从句，需要连词且在从句中做 tell 的直接宾语；所以用 what， that 在名词性从句中补充当成分，没有实在意义。而B、C连接副词，在从句中只做状语。故答案为D。
