備戰2016屆高考英語(通用版)一輪復習專題16 狀語從句
c.in case
d.so that
解析:此題考查目的狀語從句的用法。as soon as“一……就”, as a result “結果是”,in case“萬一”,so that“以便于”。
答案:d
【示例8】scientists say it may be five or six years _____ it is possible to test this medicine on human patients.
a.since
b.after
c.before
d.when
解析:根據句子的意思,科學家對藥品先要進行反復試驗后才能用于病人身上,因此答案選c。本題考查了before的固定句型,即it was/will be+時間段+before+主+謂(did/do)。
答案:c
特別提示:要選對連詞,一定要清楚主從句之間的語意和邏輯關系。
【示例9】—dad,i’ve finished my assignment.
—good, and _____ you play or watch tv, you mustn’t disturb me.
a.whenever
b.whether
c.whatever
d.no matter
解析:根據題干出現的可供選擇的兩個動作play和watch tv可判斷出應選whether。whether可引導讓步狀語從句,意思是“無論”。句意為:無論你是玩還是看電視,都不要打擾我。
答案:b
【示例10】john shut everybody out of the kitchen _____ he could prepare his grand surprise for the party.
a.which
b.when
c.so that
d.as if
解析:so that引導目的狀語從句,表示約翰的目的是準備給參加聚會的人們一個驚喜。
答案:c

怎樣做好狀語從句試題呢?
首先我們應該系統地掌握狀語從句的基本知識,把握每個連詞的具體用法;其次我們要正確區分容易混淆的連詞,像as,when,while,since,even if,as if等;再者,要善于理清句子的邏輯關系,要具備分析長難句的能力。
要特別注意as引導讓步狀語從句、時間狀語從句、方式狀語從句和原因狀語從句的不同用法。例如:
as time went on,einstein’s theory proved to be correct.(時間)
as(=since) the weather is fine,let’s go.(原因)
do as you like.(方式)
child as/though he is,he knows a lot.(讓步)
思維鏈接
【示例11】_____ i explained on the phone, your request will be considered at the next meeting.
a.when
b.after
c.as
d.since
解析:此題考查as引導定語從句和狀語從句的區別。此題中as引導的是非限制性定語從句,as指代后面整句話的內容,意為“正如……”。句子意思是:正如我在電話里所解釋的,你的要求會在下次會議上考慮。a和b兩項都指時間,d項表示“既然”,指原因,都引導狀語從句。
答案:c
特別提示:since既可以引導時間狀語從句,表示“自從……開始”,也可以引導原因狀語從句,表示“因為、既然”。
it’s/it has been 10 years since he enjoyed a good dinner.
since you have finished your work,you are free to do what you like.
