【示例1】it is almost five years ______ we saw each other last time.
a.before
b.since
c.after
d.when
解析:此題考查時間狀語從句的用法。這是一個典型的句型結構：it is/has been+段時間+since+句子(一般過去時)。句子意思是：自從我們上次見面幾乎有五年了。
答案：b
【示例2】there were dirty marks on her trousers ______ she had wiped her hands.
a.where
b.which
c.when
d.that
解析:根據句子結構，由于從句結構完整，可排除b、d兩項；前面的先行詞是on her trousers表地點，where在此引導狀語從句，where相當于in the places where，本句意思是：在她褲子上擦手的地方有臟跡。
答案：a
特別提示：學會將where引導的狀語從句轉換成介詞短語(地點)+where引導的定語從句是逐步掌握這種用法的好辦法。
【示例3】we were told we should follow the main road _____ we reached the central railway station.
a.whenever
b.until
c.while
d.wherever
解析:根據兩句子的關系——不存在讓步，從而可排除選項a、d；再根據句意，表示until前面的動作或者狀態一直持續到until后面的地點或時間。答案選b。本句意為：有人告訴我們應沿大路走，一直走到中心車站。
答案：b
【示例4】you can eat food free in my restaurant _____ you like.
a.whenever
b.wherever
c.whatever
d.however
解析:主句部分不缺主、賓、賓補成分，也有具體的地點狀語，故選a。本句意為：無論任何時候你都能在我飯店里免費吃飯。
答案：a
【示例5】we were swimming in the lake _____ suddenly the storm started.
a.when
b.while
c.until
d.before
解析:when表示這時突然,相當于suddenly。其常用結構有were/was doing...when...；were/was about to do...when...；had/had not done...when...。
答案：a
【示例6】you should try to get a good night’s sleep _____ much work you have to do.
a.however
b.no matter
c.although
d.whatever
解析:根據句子結構，排除選項b、c，因b項后面需連接副詞when，how，where或連接代詞who，what，而c項后面的句子不能倒裝；當名詞前有much，many，little，few等修飾時，前面不能用whatever，故選a。
答案：a
【示例7】i’d like to arrive 20 minutes early _____ i can have time for a cup of tea.
a.as soon as
b.as a result
