11.C （主语从句,Whoever=Anyone who,故A不对；而D选项who是疑问代词,不能选）
12.B （表语从句,从句意看,从句中缺少表示地点的状语,故选B来引导表语从句）
13.A （这是一句让步状语从句的倒装句结构：形容词/名词+ as / though +其他部分,相当于Though he was a little boy,he had ...；注意：在这个结构中,也可以用though但不能用although,而且如果是句首为名词的话,这个名词前不能用a或the之类的冠词.）
14.B （in case意为“以免...”,as long as 意思是“只要”,now that意思为“既然,因为”）
15.A
16.C
（第15题和16题都是定语从句,先行词都是day,但是15题中的day在定语从句中做时间状语,所以用when来引导,或者用on which,但不能用in which,因为只能说joined our club on that day；第16题中的day在定语从句中做spent这个动词的宾语,相当于spent the three days with you,故应选C,也可以用which或者省略关系代词.）
