例如：

注意：
(1)while意为“当…期间”，从句中的谓语动词一般用进行时态。
例如：
Take notes while you are listening to the teacher.
(2)while侧重主句中谓语动词表示的动作或存在的状态与从句谓语动词所表示的动作或存在的状态的对比，常译为“而”。

(3)not…until,直到……才，主句谓语动词必须是非持续性动词而且主句是否定式，从句为肯定式。

2、原因状语从句：引导原因状语从句的连词有：because/as/since等。
例如：
His sister is in bed because she is ill.
注意：含原因状语从句的复合句，有时可以转换为用so连接的并列句，故because和so不能同时出现在一个句子中。

(2)if……not常译作“如果不…”，相当于unless,unless含有否定意义，译作“假如不”，“除非”。

You will fail unless you work hard.
(3)用if改写“祈使句+and+简单句”这一句子结构中的祈使句时，要在祈使句前加if you,并去掉并列连词and.
例如：

If you study hard,you will catch up with us.

5、目的和结构状语从句：引导目的状语从句的连词有so that;引导结果状语从句的'连词有so …that…，such…that….
(1)so是副词，修饰形容词或副词。
So +adj/adv+that

(2)such是形容词，修饰名词。
Such+a/an+adj+n(可数名词单数)+that…
Such+adj+n(不可数名词单数，可数名词复数)+that…

(4)so …that的主从复合句在转换为简单句时，可选用下列四种结构。
Too…to do sth too…for sb to do
…enough to do sth enough for sb to do

He dose not run as/so fast as you .
(2)表示甲程度高于乙时，用“形容词、副词的比较级+than引导的”从句结构。

例如：

初中英语知识点总结 篇6
知识点总结
一、 形容词是用来描写或修饰名词或代词，说明人或事物的特征或性质的， 形容词往往被译成“···的”。用法如下:
1.做定语。e.g. This is an old house.
2.做表语。e.g.I am sorry to hear that.
3.做宾语不足语。e.g.She made her mother angry.
4.形容词在句中的位置。 形容词做定语修饰名词时，放在名词前面。修饰不定代词时要放在不定代词之后。
e.g.She is a clever girl.
I saw something white in the water.
5.某些形容词前加上定冠词the,可以代表一类人或东西，可以用作主语，宾语等。做主语时当复数看待。
e.g.The old are well looked after.
We all love the beautiful.
二、 形容词的等级变化
在英语中形容词有原级，比较级和最高级之分。原级就是它们的原形，比较级和最高级有规则变化和不规则变化。
（一）形容词的比较级和最高级变化
1.规则变化
单音节词和部分双音节词
(1)一般在词尾加er,est. hard---harder---hardest great---greater---greatest
(2)以字母e结尾的加r,st. nice---nicer----nicest able---abler----ablest
(3)重读闭音节中末尾只有一个辅音字母时，双写辅音字母，再加er,est.
big---bigger---biggest （另外还有fat， red，hot,wet,sad,mad ,thin )
(4) 以 -y 结尾,但 -y 前是辅音字母的形容词的比较级和最高级是把 -y 去掉,加 上 -ier 和-est 构成. happy (原形) happier (比较级) happiest (最高级)
(5)双音节和多音节形容词的比较级和最高级需用more 和 most 加在形容词前面来构成。
例如： beautiful (原级) difficult (原级)
more beautiful (比较级) more difficult (比较级)
most beautiful (最高级) most difficult (最高级)
2、 常用的不规则变化的形容词的比较级和最高级:
原级 比较级 最高级
good better best
many more most
much more most
bad worse worst
little less least
ill worse worst
far farther(further) farthest(furthest)
三、形容词比较等级的用法:
1、形容词的比较级用于两个人或事物的比较,其结构形式如下:
主语+谓语(系动词)+ 形容词比较级+than+ 对比成分。例如：Our teacher is taller than we are. 我们老师的个子比我们的高。
比较级前面可以用even, still, yet , any, much, rather, a little, a lot, by far等修饰语用以加强语气或表示比较程度。
2、形容词最高级的用法: 形容词最高级用于两个以上的人和物进行比较,形容词最高级 前必须加the,后面多用of……， in……短语表示范围：其结构形式为:
主语+谓语(系动词)+the+形容词最高级+名词+表示范围的短语或从句。
She is the best student in her class. 她是班上最好的学生。
He is the tallest of the three boys.他是三个男孩中最高的一个。
四、 有关比较等级的特殊句型及应注意的问题
1. “比较级 ＋ and + 比较级”或“more and more / less and less + 原级”结构表示“越来越……”的意思，与这类结构搭配的常用动词有grow, get, become等。
She felt herself becoming more and more nervous.她觉得自己越来越紧张。
its getting colder and colder.天气越来越冷。
2. the + 比较级 + of the two + 名词。表示“两个中较···的一个
Jane is the taller of the two children in our family. Jane是我家两个孩子中较高的。
3. “the + 比较级……，the + 比较级……”，表示“越……，越……”。
The more magazines you sell, the more money you will get.你卖的杂志越多，你挣的钱就越多。
4.“．．．as + 形容词 + as．．．”或“．．．as + 形容词 + 名词 + as．．．”构成，表示同等比较。
常见考法
对于形容词的考查，多以单选或词语运用的形式考查学生在具体语境中灵活运用形容词的能力，尤其是在各种比较句型中灵活运用形容词。
例如： Which month is____, June, July or August?
A. hot B. hotter C. hottest D. the hottest
解析：三者及以上比较用最高级形式，形容词最高级前必须加the，所以应用the hottest
误区提醒
在分辨比较等级时，对于易混淆形容词、副词，要谨慎对待。
典型例题：Dont just believe the ad.That kind of camera is it says.
A.as good as B.not so good as C.as well as D.not as well as
解析：根据第二句的谓语动词be可以确定空白处缺少表语。此处的表语应由形容词充当，而 well表示“好”是副词，因此排除 C和D；根据第一句的意思我们可以知道说话者的观点，故此排除A.
答案：B
