例1、Generally speaking, _________ according to directions, the drug has no sid-effect.
A. when taking B. when taken C. when to take D. when to be taken
答案為B。
[解析] 這是一個(gè)由when引導(dǎo)的時(shí)間狀語(yǔ)從句,原句應(yīng)為“Generally speaking ,when it is taken according…”。由于take用被動(dòng)時(shí),主從句主語(yǔ)一致,因此從句中的it was可以被省略,簡(jiǎn)化為when taken…分詞短語(yǔ)作狀語(yǔ),而選A、C時(shí)則缺乏主語(yǔ)。譯文:通常地說(shuō),當(dāng)這藥按照指導(dǎo)說(shuō)明被服用的話是沒(méi)有副作用的。
例2、-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
答案為B。
[解析] no matter不能直接引導(dǎo)讓步狀語(yǔ)從句,應(yīng)用no matter + wh族疑問(wèn)詞方可,故排除D;盡管A、C都有“無(wú)論”的意思,但只有B項(xiàng)whether可與or連用,表示選擇,即“無(wú)論你玩還是看電視,不許打擾我”!
例3、The famous scientist grew up _______ he was born and in 1930 he came to Shanghai.
A. when B. whenever C. where D. wherever
答案為C。
[解析] where引導(dǎo)的是地點(diǎn)狀語(yǔ)從句。譯文:這位著名的科學(xué)家在他的出生地長(zhǎng)大,1930年他來(lái)到上海。因?yàn)樵趶木渲杏斜硎緯r(shí)間的介詞短語(yǔ)in 1930,所以可以排除when和whenever; wherever引導(dǎo)讓步狀語(yǔ),意思是“無(wú)論在哪里”,與句意不符。
例4、________, I have never seen anyone who's as capable as John.
A. As long as I have traveled B. Now that I have traveled so much
C. Much as I have traveled D. As I have traveled so much
答案為C。
[解析] 這是一個(gè)讓步狀語(yǔ)從句。as在引導(dǎo)讓步狀語(yǔ)從句時(shí),要把形容詞或副詞放在它的前面。如果是名詞,一般不加冠詞。如:Child as he is, he has learned two thousand new words .As long
as“只要……”引導(dǎo)條件狀語(yǔ)從句;Now that“既然”引導(dǎo)原因狀語(yǔ)從句;As“因?yàn)椤币龑?dǎo)原因狀語(yǔ)從句。譯文:雖然我走過(guò)了那么多地方,我從來(lái)沒(méi)有見(jiàn)過(guò)像約翰這樣有能力的人。
例5、In such dry weather, the flowers will have to be watered if they________.
A. have survived B. are to survive C. would survive D. will survive
答案為B。
[解析] 這是一個(gè)條件狀語(yǔ)從句,主句用了一般將來(lái)時(shí)態(tài)。在條件狀語(yǔ)從句中,一般不能使用將來(lái)時(shí),但能和be to do的形式連用,所以應(yīng)填are to survive。譯文:在如此干旱的天氣里,如果你想要花成活,就得給它們澆水。
例6、The WTO cannot live up to its name _____ it does not include a country that is home to one fifth of mankind.
A.a(chǎn)s long as B.while C.if D.even though
答案選C。
[解析] 從句子意思可知,是一個(gè)條件狀語(yǔ)從句。as long as“只要……”引導(dǎo)條件狀語(yǔ)從句經(jīng)常用肯定句,所以要填if。譯文:如果WTO不包括一個(gè)占人類五分之一的國(guó)家,它就名不符實(shí)了。
例7、She found her calculator ________ she lost it.
A. where B. when C. in which D. that
答案為A。
[解析] 這是一個(gè)地點(diǎn)狀語(yǔ)從句,意思是“東西是在丟的地方找到的!眎n which用于定語(yǔ)從句中,其前必須有先行詞。這個(gè)句子中沒(méi)有先行詞,所以不能填in which!
例8、-I'm going to the post office.
- ________you're there, can you get me some stamps?
A. As B. While C. Because D. If
答案為B。
[解析] while引導(dǎo)時(shí)間狀語(yǔ)從句,意思是“當(dāng)……時(shí)”。這句話的意思是“當(dāng)你在那兒的時(shí)候,是否能給我買一些郵票?”as雖然也可以引導(dǎo)時(shí)間狀語(yǔ)從句,但其意思是“一邊……一邊……”;because引導(dǎo)的是原因狀語(yǔ)從句;if引導(dǎo)的是條件狀語(yǔ)從句,對(duì)方已經(jīng)說(shuō)明要到郵局去,不能再作假設(shè)。
例9、You should make it a rule to leave things ________you can find them again.
A. when B. where C. then D. there
答案為B。
[解析] where引導(dǎo)地點(diǎn)狀語(yǔ)從句。這句話的意思是“你應(yīng)該作出一個(gè)規(guī)矩,把東西放在你能再找到它們的地方。”
例10、We'll have to finish the job, ________.
A. long it takes however B. it takes however long
C. long however it takes D. however long it takes
答案選D。

5、as, though 引導(dǎo)的倒裝句
as / though引導(dǎo)的讓步從句必須把表語(yǔ)或狀語(yǔ)提前(形容詞、副詞、分詞、實(shí)義動(dòng)詞提前)。句首名詞不能帶任何冠詞。
如句首是實(shí)義動(dòng)詞,助動(dòng)詞放在主語(yǔ)后。如果實(shí)義動(dòng)詞有賓語(yǔ)和狀語(yǔ),隨實(shí)義動(dòng)詞一起放在主語(yǔ)之前。
例如:Child as /though he was, he knew what was the right thing to do.
= Though he was a small child, he knew what was the right thing to do.
Try hard as he will, he never seems able to do the work satisfactorily.
= Though he tries hard, he never seems…
雖然他盡了努力,但他的工作總做的不盡人意。
