a.that；which b.when；as

解析：選c�？疾闋钫Z從句和賓語從句的引導詞。句意：我離開我的家鄉佛羅里達州已經好久了，我開車到城里去，希望能看到我小時候在那里理發的那家理發店。第一空處是it be＋時間段＋since引導的狀語從句，表示“自從某事發生到現在有多長時間”；第二空用where引導定語從句，修飾shop，在從句中作地點狀語。

a.since b.as
c.though d.unless
解析：選b。考查狀語從句。句意：卡車對這座房子造成了嚴重的損壞。我們最好保持原樣直到警察到來。as引導方式狀語從句，意為“照……方式”。leave things as they are意為“順其自然”。
16.________his courage，________i don’t think he acted wisely.
a.much as i admire；/
b.much as do i admire；but
c.as i admire much；still
d.although i admire；but
解析：選a。句意：盡管我很欽佩他的勇氣，但我認為他這樣做很不明智。as引導讓步狀語從句時要倒裝，本句的倒裝結構為：副詞＋as＋主語＋謂語。as為連詞引導讓步狀語從句，后面的句子為主句，不加連詞。

c.as d.it
解析：選c�？疾槎ㄕZ從句的引導詞。表示“正如……”時，只能用關系代詞as。as引導的從句放在主句的前面、中間或末尾都可以。
