高考臨近，以下是狀語從句易錯考點分析的一些重要歸納，希望對大家有所幫助！

一、誤用not…unti…句式

“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】容易誤選B，誤認為這是考查 not…until…結構。

【分析】最佳答案選 C。句中的 your work is being done 表明“你正在做作業(yè)”，選 as 表原因。

二、混淆as與while的區(qū)別

“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】容易誤選A。

【分析】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(qū)別，就是這樣用的 as 從句的謂語不能是狀態(tài)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(tài)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”)

請做以下兩題，答案均選 while，不選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引導地點狀語從句

The visitor asked to have his picture taken _______ stood the famous tower.

A. that B. at which

C. when D. where

【陷阱】幾個干擾項均有可能誤選。

【分析】最佳答案選 D。where 表示“在……的地方”，用以引導地點狀語從句。注意，此題還涉及倒裝，即此句的主語是 the famous tower，謂語是 stood，正常詞序為 where the famous tower stood，使用倒裝是為了保持句子平衡，避免頭重腳輕(from www.nmet168.com)。

四、忽略狀語從句省略句

“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】幾個干擾項均有可能誤選。

【分析】最佳答案選 C。此句為省略句，答句句首的 No 表明其后省略的是一個否定句，全句補充完整為：She can’t play computer games unless she has finished her homework. 請做類似試題(答案均選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.”

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用作連詞

“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】幾個干擾項均有可能誤選。

【分析】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。如以下試題也選 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
