英语学习资料：状语从句易错考点分析 以下文字资料是由小编为大家搜集整理后发布的内容，让我们赶快一起来看一下吧！
“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。
二、混淆as与while的区别
“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
三、忽略where引导地点状语从句
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。where 表示“在……的地方”，用以引导地点状语从句。注意，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(from nmet168)。
四、忽略状语从句省略句
“Shall Mary e and play puter 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 puter 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 e to join us in the work?” “No, _______ we promise him more money.”
A. when B. unless
C. unless D. as soon as
(3) “Can you finish the work in time?” “No, _______ we don’t sleep throughout the night.”
五、注意the moment用作连词
“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
【陷阱】几个干扰项均有可能误选。
【分析】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。如以下试题也选 B：
(1)“Did you remember to give Mary the money you owed her?” “Yes, I gave it to her ________ I saw her.”
A. while B. the moment
C. suddenly D. until
(2) The doorkeeper gave the alarm _______ he saw the smoke.
A. while B. the instant
C. suddenly D. before
(3) I raised the alarm _______ I saw the smoke.
A. while B. the minute
C. suddenly D. since
