　　5．(2011·重慶)To show our respect, we usually have to take our gloves off________we are to shake hands with. A．whichever

　　B．whenever C．whoever

　　D．wherever 解析　 考查狀語從句的連詞。whoever引導讓步狀語從句，相當于no matter who。 答案　C

　　1．讓步狀語從句可由although，though，as，while，even if(though)，whatever，whether...or...，no matter who (when，what...)等引導。 Although/Though she works very hard，(yet) she makes very slow progress.盡管她學習很努力，但還是進步不快。 Whenever I’m unhappy(＝No matter when I’m unhappy)，it is my friend who cheers me up. 不管什么時候我不高興，總是我的朋友給我鼓勵。 【專家提醒】 (1)however引導讓步狀語從句時，與它所修飾的詞一起放在句首。 (2)英語不允許在though 或although從句后同時用but。如果要強調前后兩個部分的對比意義，可以在主句前加上yet或still。 2．as引導的讓步狀語從句的常見的幾種倒裝方式 (1)如果從句的謂語部分為“不及物動詞＋副詞”時，常將從句中的副詞提到從句的句首。 Hard as you may try，you will not succeed. 盡管你努力了，你可能不會成功。 (2)如果從句的謂語部分為“情態動詞＋不及物動詞”，常將這個不及物動詞提到從句的句首。 Wait as you may，he will not see you. 盡管你等了，他可能不會見你。 (3)如果從句的謂語部分是“系動詞＋單數名詞”，則常將這個作表語的名詞提前，但這個名詞前面的不定冠詞要省略。 Child as he is，he can tell right from wrong. 盡管他還是個孩子，他能明辨是非。 3．while作“盡管”講引導讓步狀語從句時往往放在句首 While I understand your viewpoint，I don’t agree with you. 盡管我明白你的觀點，我不贊成你。

　　D. though 解析　 考查狀語從句的用法。根據句意，空格處需要填入“好像，仿佛”。故選A。 答案　A

　　2．(2009·天津)I travel to the Binhai New Area by light railway every day，________do many businessmen who live in downtown Tianjin. A．as

　　B．which C．when

　　D．though 解析　 句意：我像許多住在天津鬧市區的商人一樣，每天乘坐輕軌到濱海新區上班。as引導方式狀語從句時意為“正如，就像……一樣”。 答案　A

　　1．as 和just as 二者都表示“如……；猶如……，正如……”。just as 比as強調的語氣更強。例如： In the early days, people could not count as we do now. 在早期日子中，人們不和我們現在一樣能計數。 Most plants need sunlight just as they need water. 大部植物像它們需要水一樣，也需要陽光。

　　2．as if 和as though as if 或as though從句可以用陳述語氣，表示可能符合事實的情況；也可以用虛擬語氣，表示不符合事實或與事實相反的情況，意為“好像，仿佛”。例如： It looks as though it is going to rain. 天看起來要下雨。 He spoke as if he were a philosopher. 他說話就像是一位哲學家。(從句動詞與主語謂語同時發生，從句謂語要用一般過去時)

　　He speaks as if he had been to the moon. 他談起話來就好像是去過月球。(從句動作發生在主句謂語之前，從句謂語要用過去完成時) He speaks as if he would fly to the moon. 他談起話來就好像是要飛往月球。(從句動詞發生在主句謂語之后，從句謂語要用would/could/might＋do) Adverbial Clauses of Reason(原因狀語從句）

　　1．“ May I go and play with Dick this afternoon, Mum？”“ No, you can’t go out________your work is being done.” A. before

　　B. until C. as

　　D. the moment 【易誤分析】　容易誤選B，誤認為這是考查 not...until...結構。 【名師指津】　最佳答案選 C。句中的 your work is being done 表明“你正在做作業”，選 as 表原因。 2. “I’m going to the post office.” “________you’re there, can you get me some stamps？” A. As

　　B. While C. Because

　　D. If 【易誤分析】　容易誤選A。 【名師指津】　最佳答案選 B。盡管 as 和 while 均可用作從屬連詞引導時間狀語從句，表示“當……的時候”，但兩者有一個重要區別，就是這樣用的 as 從句的謂語不能是狀態動詞。當然，如果 as 不是表示“當……的時候”，其謂語是完全可以用狀態動詞的。如： I went to bed early, as I was exhausted. 我很累了，所以很早就上床睡了。(此句中的 as 表示原因，意為“因為”、“由于”)

　　3. After the war, a new school building was put up________there had once been a theatre.

　　A. that

　　B. when C. which

　　D. where 【易誤分析】　幾個干擾項均有可能誤選。 【名師指津】　最佳答案選 D。where 在此引導地點狀語從句，其意為“(在)……的地方”。 4. The visitor asked to have his picture taken________ stood the famous tower. A. that

　　B. at which C. when

　　D. where 【易誤分析】　幾個干擾項均有可能誤選。 【名師指津】　最佳答案選 D。此題與上面一題有些相似，但又有所不同：相似的是，where 均表示“在……的地方”，均用以引導地點狀語從句；不同的是，此題還涉及倒裝，即此句的主語是 the famous tower，謂語是 stood，正常語序為 where the famous tower stood，使用倒裝是為了保持句子平衡，避免頭重腳輕。 5. They kept trying________they must have known it was hopeless. A. if

　　B. because C. when

　　D. where 【易誤分析】　幾個干擾項均有可能誤選。 【名師指津】　最佳答案選 C。when 在此的意思不是“當……的時候”，而是“盡管”、“雖然”的意思。又如： He walks when he might take a taxi. 盡管他可以坐出租車，但他卻走路。 He stopped trying when he might have succeeded next time. 盡管他本來下次就可以成功的了，但他卻停止努力了。 The boy was restless when he should have listened to the teacher carefully. 這男孩子本來應該專心聽老師講的，但他卻坐立不安。 有許多同學只知道 when 表示“當……的時候”，而不知道它還有其他許多意思，除上面提到的表示“盡管”、“雖然”外，when 還可表示“既然”、“考慮到”。請做下面的試題(答案選D)： Why do you want a new job________you’ve got such a good one already? A. that

　　B. where C. which

　　D. when 6. He was about to tell me the secret________someone patted him on the shoulder. A. as

　　B. until C. when

　　D. while

　　【易誤分析】　幾個干擾項均有可能誤選。 【名師指津】　最佳答案選 C。when 意為“這時(突然)”，主要用于某一動作突然發生于另一動作正在進行或剛要發生之時。此時的 when 可以連用副詞 suddenly，也可以不連用它，但值得注意的是，同學們不能單獨用 suddenly 來代替 when。

　　7. The fire went on for quite some time________it was brought under control. A. when

　　B. since C. after

　　D. before

　　【易誤分析】　幾個干擾項均有可能誤選。 【名師指津】　最佳答案選 D。before 意為“在……之前”，句意是“大火在得到控制之前燃燒了相當一段時間”。

　　8. Mother asked me to take more money________something unexpected should happen. A. in case

　　B. so that C. in order that

　　D. when 【易誤分析】　幾個干擾項均有可能誤選。 【名師指津】　最佳答案選 A。in case 起連詞作用，用以引導狀語從句，主要有兩種意思：一是表示條件，意為“如果”、“萬一”；二是表示“目的”，意為“以防”、“免得”。

　　9.________your composition carefully, some spelling mistakes can be avoided.

　　A. Having checked

　　B. Check

　　C. If you check

　　D. To check 【易誤分析】　幾個干擾項均有可能誤選，尤其可能誤選A。 【名師指津】　最佳答案選 C。前面一個分句為條件狀語從句，后面一個分句為主語。現分析幾個干擾項：選項 A 和 D 均為非謂語動詞，根據英語語法習慣，非謂語動詞作狀語時，其邏輯主語應與句子主語一致，而此句的 some spelling mistakes 顯然不能用作 having checked 或 to check 的邏輯主語，故不能選為答案；若選 B，則兩個句子之間缺少必要的連詞，也不對。

　　10. “When did he leave the classroom？” “He left________you turned back to write on the blackboard.” A. the time

　　B. the moment C. until

　　D. since 【易誤分析】　幾個干擾項均有可能誤選。 【名師指津】　最佳答案選 B。the moment 用作連詞，意為“一……就……”，相當于 as soon as。類似地，the minute, the instant 也可用作連詞，表示“一……就……”的意思。

　　1．—Did you return Fred’s call? —I didn’t need to________I’ll see him tomorrow. A. thoughB. unless C. when

　　D. because 解析　 句意是：“你給Fred回電話了沒有？”“我沒有回電話，因為我明天就會見到他。”所以要用 because引導原因狀語從句。 答案　D

　　2．________well prepared you are, you still need a lot of luck in mountain climbing. A. However

　　B. Whatever C. No matter

　　D. Although 解析　 句意是：不管你準備得有多么好，你在爬山運動中仍需要很大的運氣。從句與主句是轉折關系，要用連接副詞However引導讓步狀語從句，同時作狀語修飾well。 答案　A 3. I used to love that film________I was a child, but I don’t feel it that way any more. A. once

　　B. when C. since

　　D. although 解析　 句意是：當我還是一個小孩子的時候，曾喜歡過那部電影，但是現在我再也沒有那種感覺了。根據句意可知，此處要用when引導時間狀語從句。once 一旦；一……就……；since自從……以來；既然；although雖然……但是……。 答案　B 4. Failure is never pleasurable，but it can make a positive contribution to your life________you learn to use it. A. since

　　B. once C. until

　　D. unless 解析　 句意是：失敗永遠不是令人愉快的事情。但是，一旦你學會利用它，它就會給你的生活帶來積極的促進作用。根據題意可知，從句是主句發生的條件，故用once表示“一旦”。 答案　B

　　5. That was really a splendid evening. It’s years________I enjoyed myself so much.
