高一英语学习:三四单元重难点句型归纳一

☆句型归纳☆

1. You shouldn't go rafting unless you know how to swim, and you should always wear a life jacket. 除非你会游泳,而且要一直穿着救生衣,否则就不应该去做漂流运动。

该句中的unless引导状语从句。例如:One can't learn a foreign language well unless he studies hard.

unless引导的条件状语从句,一般可以与if...not...互换。还要注意unless引导的从句经常可以省略。

【考例】(200l北京春招)The men will have to wait all day ____ the doctor works faster.

A. if B. unless C. whether D. that

[考查目标]状语从句。

[答案与解析]B 句子意思是“如果医生不快点工作,

这些人将不得不等一整天。”应该选unless。

2. Eco-travel is a way to find out what can be done to help animals and plants as well as people. 生态游可以找到既帮助别人.又帮助动植物的途径。

该句中的as well as是连词,连接两个并列成分。例如: He can speak German as well as French.

常见的用法:

1. well是副词,意思是“好,优秀”,as well as是形容词 同级比较结构。

2. as well as是固定短语,意思是“和”,相当于"not only … but also..."。

3. as well as连接两个并列成分作主语时,句子的谓语动词应该与前面那个名词或代词的人称或数保持一致。

4. as well as还可当作复杂介词用,意思是“除了……之外,还有”;相当于"besides,apart from"。

5. as well,是副词短语,意思是“也”,相当于“too / also”常位于句尾,与too位置相当。

6. may / might as well do sth 表示“还是……的好”。

【考例】(NMET 1994) John plays football ____, if not better than David.

A. as well B. as well as C. so well D. so well as

[考查目标] as well as连接比较状语从句。

[答案与解析]B 该句中 if not better than相当于插入语,起干扰作用,如果不予考虑,原句就变成了同级比较结构 "John plays football as well as David"。
