　　状语从句考点
        　　◆典型陷阱题分析◆
        　　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
        　　【陷阱】容易误选B，误认为这是考查 not…until…结构。
        　　【分析】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
        　　【陷阱】容易误选A。
        　　【分析】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”)
        　　请做以下两题，答案均选 while，不选as：
        　　(1) _______ you are at home alone, please don’t leave the door open.
        　　A. While B. As
        　　C. Before D. How
        　　(2) _______ you are alone with her, tell her that you like her.
        　　A. While B. As
        　　C. After D. How
        　　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
        　　【陷阱】几个干扰项均有可能误选。
        　　【分析】最佳答案选 D。where 在此引导地点状语从句，其意为“(在)……的地方”。请做以下类似试题(答案均选 where)：
        　　(1) The famous scientist grew up _______ he was born and in 1930 he came to Shanghai.
        　　A. when B. whenever
        　　C. where D. wherever
        　　(2) She found her calculator _______ she lost it.
        　　A. where B. while
        　　C. in which D. that
        　　(3) You should make it a rule to leave things _______ you can find them again.
        　　A. when B. where
        　　C. then D. which
        　　(4) When you read the book, you’d better make a mark _____ you have any questions.
        　　A. at which B. at where
        　　C. the place where D. where
        　　(5) You should let your children play ______ you can see them.
        　　A. where B. when
        　　C. in which D. that
        　　(6) Now he works in the factory ______ his father used to work.
        　　A. where B. when
        　　C. in which D. that
        　　4. The visitor asked to have his picture taken _______ stood the famous tower.
        　　A. that B. at which
        　　C. when D. where
        　　【陷阱】几个干扰项均有可能误选。
        　　【分析】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，正常词序为 where the famous tower stood，使用倒装是为了保持句子平衡，避免头重脚轻。
        　　4. They kept trying _____ they must have known it was hopeless.
        　　A. if B. because
        　　C. when D. where
        　　【陷阱】几个干扰项均有可能误选。
        　　【分析】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
        　　5. He was about to tell me the secret ______ someone patted him on the shoulder.
        　　A. as B. until
        　　C. when D. while
        　　【陷阱】几个干扰项均有可能误选。
        　　【分析】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，如下面各题的答案选A，不选B：
        　　(1) I was about to go out ______ the telephone rang.
        　　A. when B. suddenly
        　　C. as soon as D. directly
        　　(2) We were swimming in the lake _______ the storm started.
        　　A. when B. suddenly
        　　C. until D. before
        　　(3) She was walking down the road _______ she heard someone shouting for help.
        　　A. when B. suddenly
        　　C. until D. before
        　　6. The fire went on for quite some time _______ it was brought under control.
        　　A. when B. since
        　　C. after D. before
        　　【陷阱】几个干扰项均有可能误选。

        　　A. until B. when
        　　C. before D. as

        　　A. in case B. so that
        　　C. in order that D. when
        　　【陷阱】几个干扰项均有可能误选。
        　　【分析】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”。如以下各题也都选 in case：
        　　(1) ________ I forget, please remind me about it.
        　　A. In case B. So that
        　　C. In order that D. When
        　　(2) Take your umbrella just ________ it rains.

        　　A. Having checked B. Check
        　　C. If you check D. To check
        　　【陷阱】几个干扰项均有可能误选，尤其可能误选A。
        　　【分析】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。请做类似试题(答案均选 C)：
        　　(1) ________ more careful, the work might have been done better.
        　　A. Being B. Having been
        　　C. If you had been D. To have been

        　　9. “Shall Mary come and play computer games?” “No, _______ she has finished her homework.”
        　　A. when B. since
        　　C. unless D. as soon as
        　　【陷阱】几个干扰项均有可能误选。
        　　【分析】最佳答案选 C。此句为省略句，答句句首的 No 表明其后省略的是一个否定句，全句补充完整为：She can’t play computer games unless she has finished her homework. 请做类似试题(答案均选B)：
        　　(1) “Would you mind my sitting here with you?” “No, ______ you aren’t too noisy.”
        　　A. when B. if
        　　C. unless D. as soon as
        　　(2) “Will he agree to come to join us in the work?” “No, _______ we promise him more money.”
