1．让步状语从句可由although，though，as，while，even if(though)，whatever，whether...or...，no matter who (when，what...)等引导。 Although/Though she works very hard，(yet) she makes very slow progress.尽管她学习很努力，但还是进步不快。 Whenever I’m unhappy(＝No matter when I’m unhappy)，it is my friend who cheers me up. 不管什么时候我不高兴，总是我的朋友给我鼓励。 【专家提醒】 (1)however引导让步状语从句时，与它所修饰的词一起放在句首。 (2)英语不允许在though 或although从句后同时用but。如果要强调前后两个部分的对比意义，可以在主句前加上yet或still。 2．as引导的让步状语从句的常见的几种倒装方式 (1)如果从句的谓语部分为“不及物动词＋副词”时，常将从句中的副词提到从句的句首。 Hard as you may try，you will not succeed. 尽管你努力了，你可能不会成功。 (2)如果从句的谓语部分为“情态动词＋不及物动词”，常将这个不及物动词提到从句的句首。 Wait as you may，he will not see you. 尽管你等了，他可能不会见你。 (3)如果从句的谓语部分是“系动词＋单数名词”，则常将这个作表语的名词提前，但这个名词前面的不定冠词要省略。 Child as he is，he can tell right from wrong. 尽管他还是个孩子，他能明辨是非。 3．while作“尽管”讲引导让步状语从句时往往放在句首 While I understand your viewpoint，I don’t agree with you. 尽管我明白你的观点，我不赞成你。

B．which C．when
D．though 解析 句意：我像许多住在天津闹市区的商人一样，每天乘坐轻轨到滨海新区上班。as引导方式状语从句时意为“正如，就像……一样”。 答案 A
1．as 和just as 二者都表示“如……；犹如……，正如……”。just as 比as强调的语气更强。例如： In the early days, people could not count as we do now. 在早期日子中，人们不和我们现在一样能计数。 Most plants need sunlight just as they need water. 大部植物像它们需要水一样，也需要阳光。
2．as if 和as though as if 或as though从句可以用陈述语气，表示可能符合事实的情况；也可以用虚拟语气，表示不符合事实或与事实相反的情况，意为“好像，仿佛”。例如： It looks as though it is going to rain. 天看起来要下雨。 He spoke as if he were a philosopher. 他说话就像是一位哲学家。(从句动词与主语谓语同时发生，从句谓语要用一般过去时)
He speaks as if he had been to the moon. 他谈起话来就好像是去过月球。(从句动作发生在主句谓语之前，从句谓语要用过去完成时) He speaks as if he would fly to the moon. 他谈起话来就好像是要飞往月球。(从句动词发生在主句谓语之后，从句谓语要用would/could/might＋do) Adverbial Clauses of Reason(原因状语从句）

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 【易误分析】 容易误选B，误认为这是考查 not...until...结构。 【名师指津】 最佳答案选 C。句中的 your work is being done 表明“你正在做作业”，选 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 【易误分析】 容易误选A。 【名师指津】 最佳答案选 B。尽管 as 和 while 均可用作从属连词引导时间状语从句，表示“当……的时候”，但两者有一个重要区别，就是这样用的 as 从句的谓语不能是状态动词。当然，如果 as 不是表示“当……的时候”，其谓语是完全可以用状态动词的。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，意为“因为”、“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 【易误分析】 几个干扰项均有可能误选。 【名师指津】 最佳答案选 D。where 在此引导地点状语从句，其意为“(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 【易误分析】 几个干扰项均有可能误选。 【名师指津】 最佳答案选 D。此题与上面一题有些相似，但又有所不同：相似的是，where 均表示“在……的地方”，均用以引导地点状语从句；不同的是，此题还涉及倒装，即此句的主语是 the famous tower，谓语是 stood，正常语序为 where the famous tower stood，使用倒装是为了保持句子平衡，避免头重脚轻。 5. They kept trying________they must have known it was hopeless. A. if
B. because C. when
D. where 【易误分析】 几个干扰项均有可能误选。 【名师指津】 最佳答案选 C。when 在此的意思不是“当……的时候”，而是“尽管”、“虽然”的意思。又如： He walks when he might take a taxi. 尽管他可以坐出租车，但他却走路。 He stopped trying when he might have succeeded next time. 尽管他本来下次就可以成功的了，但他却停止努力了。 The boy was restless when he should have listened to the teacher carefully. 这男孩子本来应该专心听老师讲的，但他却坐立不安。 有许多同学只知道 when 表示“当……的时候”，而不知道它还有其他许多意思，除上面提到的表示“尽管”、“虽然”外，when 还可表示“既然”、“考虑到”。请做下面的试题(答案选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
【易误分析】 几个干扰项均有可能误选。 【名师指津】 最佳答案选 C。when 意为“这时(突然)”，主要用于某一动作突然发生于另一动作正在进行或刚要发生之时。此时的 when 可以连用副词 suddenly，也可以不连用它，但值得注意的是，同学们不能单独用 suddenly 来代替 when。
7. The fire went on for quite some time________it was brought under control. A. when
B. since C. after
D. before
【易误分析】 几个干扰项均有可能误选。 【名师指津】 最佳答案选 D。before 意为“在……之前”，句意是“大火在得到控制之前燃烧了相当一段时间”。
8. Mother asked me to take more money________something unexpected should happen. A. in case
B. so that C. in order that
D. when 【易误分析】 几个干扰项均有可能误选。 【名师指津】 最佳答案选 A。in case 起连词作用，用以引导状语从句，主要有两种意思：一是表示条件，意为“如果”、“万一”；二是表示“目的”，意为“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 【易误分析】 几个干扰项均有可能误选，尤其可能误选A。 【名师指津】 最佳答案选 C。前面一个分句为条件状语从句，后面一个分句为主语。现分析几个干扰项：选项 A 和 D 均为非谓语动词，根据英语语法习惯，非谓语动词作状语时，其逻辑主语应与句子主语一致，而此句的 some spelling mistakes 显然不能用作 having checked 或 to check 的逻辑主语，故不能选为答案；若选 B，则两个句子之间缺少必要的连词，也不对。
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 【易误分析】 几个干扰项均有可能误选。 【名师指津】 最佳答案选 B。the moment 用作连词，意为“一……就……”，相当于 as soon as。类似地，the minute, the instant 也可用作连词，表示“一……就……”的意思。

D. because 解析 句意是：“你给Fred回电话了没有？”“我没有回电话，因为我明天就会见到他。”所以要用 because引导原因状语从句。 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：不管你准备得有多么好，你在爬山运动中仍需要很大的运气。从句与主句是转折关系，要用连接副词However引导让步状语从句，同时作状语修饰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：当我还是一个小孩子的时候，曾喜欢过那部电影，但是现在我再也没有那种感觉了。根据句意可知，此处要用when引导时间状语从句。once 一旦；一……就……；since自从……以来；既然；although虽然……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：失败永远不是令人愉快的事情。但是，一旦你学会利用它，它就会给你的生活带来积极的促进作用。根据题意可知，从句是主句发生的条件，故用once表示“一旦”。 答案 B
