2020高考英语总复习 经典易错题会诊与试题预测 第二部分单项填空 考点10副词性从句

[对症下药] A

2.(典型例题)—Shall Brown come and play computer games? —No,__ he has finished his homework.

A. when B. if C. unless D. once [考场错解] A或B

[专家把脉] 本题若选A、B没有完全领会本题含义。在答语中实际上是一个省略句，引出一个条件“除非他先完成作业，否则不会来的”。 [对症下药] C

3.(典型例题)The scientists made __ rapid progress __ they were praised by their leader.

A. so... that B./,that C. such... that D. much... that [考场错解] A

[专家把脉] so...that和such...that均可引导结果状语从句，但so后一般接形容词，构成so + adj/ adv + that结构，而such后接由形容词所修饰的名词，构成such + adj + 可数名词复数或不可数名词 + that结构。 [对症下药] C

4.(典型例题京) They worked hard __ they finished their work ahead of time. A. so B. so that C. such that D. so as to [考场错解] D

[专家把脉] 考生忽略了so as to后应接动词或动词短语，此句句意为“他们拼命干活，结果提前完成了工作”，应该用so that来引导结果状语从句，作“结果…”讲。

[对症下药] B

5.(典型例题) I will come __ Mary is invited too. A. unless B. till

C. when D. on condition that

[考场错解] A

[专家把脉] unless意为“除非”，本句句意明显，即’若Marg来的话，我也来”，故用on condltlon that引导。 [对症下药] D 专家会诊

1.条件状语从句的引导词有:if，unless，as long as，so long as，on condtion that等。

2.结果状语从句的引导词有:so...that，such...that应该正确使用so和such (1)so + adj.／adv.／分词 + that... (2)so + adj + a + 可数名词单数 + that...

(3)so + many／few／little/much + 名词 + that... 此处many／few／little／much是表示数量的形容词。

(4)such + a + adj. + 单数可数名词 + that...

(5)such + adj.+ 可数名词复数或不可数名词 + that...例: The boy is so young that he can’t go to school. He is such a young boy that he can’t go to school. He is so young a boy that he can’t go to school.

He made such rapid progress that he was praised by his mother. Soon there were so many deer that they ate up all the wild roses. 考场思维训练

命题角度 3 让步状语从句和方式状语从句的运用

1.( 典型例题) Allow children the space to voice their opinions, they are different from your own.

A. until B. even if C. unless D. as though [考场错解] D

[专家把脉] as though = as if，用在本句中明显不合语境，本句意为“请给孩子们发言的机会，即使他们的意见和你们的不统一”。even if 意为“即使”，符合语境。

[对症下药] B

2. (经典题)We should finish the important job,_ . A. long it takes however B. it takes however long

C. long however it takes D. however long it takes [考场错解] C

[专家把脉] 当however引导让步状语从句时，however可以用no matter how的替换，因此how ever后要接形容词，此外，however还应置于从句句首。 [对症下药] D

3.(典型例题建)English and French are taught here. You can choose __ you like.

A. no matter which B. whichever C. which D. whatever [考场错解] A

[专家把脉] 在让步状语从句中，“no matter + 疑问词”结构和“疑问词 + ever”结构可互换，若选A，则B也可。本题实际上是一个名词性从句，whichever既引导宾语从句，又做like的宾语。 [对症下药] B

4.(典型例题) __ he is, he will be thinking of you.

A. Wherever B. Where C. Now that D. As soon as [考场错解) B

[专家把脉] Where不能置于句首构成独立的分句。 wherever用来引导让步状语从句，相当于no matter where。 [对症下药] A

5.(典型例题) it rained heavily, they still went out.

A. If B. Unless C. Although D. Before [考场错解] B

[专家把脉] unless意为“除非……”；A、D两项明显不合句意；although用在此句中用来引导让步状语从句，意为“尽管……”
