英语四级语法知识：不定冠词的用法
冠词是虚词，本身不能单独使用，也没有词义，它用在名词的前面，帮助指明名词的含义。英语中的冠词有三种，一种是定冠词(the Definite Article)，另一种是不定冠词(the Indefinite Article)，还有一种是零冠词(Zero Article)。
不定冠词a (an)与数词one 同源，是"一个"的意思。a用于辅音音素前，一般读作[e]，而an则用于元音音素前，一般读做[en]。
1) 表示"一个"，意为one;指某人或某物，意为a certain。
A Mr. Ling is waiting for you.
2) 代表一类人或物。
A knife is a tool for cutting with.
Mr. Smith is an engineer.
3) 词组或成语。
a little / a few / a lot / a type of / a pile / a great many / many a / as a rule / in a hurry / in a minute / in a word / in a short while / after a while / have a cold / have a try / keep an eye on / all of a sudden
英语四级语法知识：定冠词的用法
定冠词the与指示代词this，that同源，有"那(这)个"的意思，但较弱，可以和一个名词连用，来表示某个或某些特定的人或东西。
1)特指双方都明白的人或物：
Take the medicine.把药吃了。
2)上文提到过的人或事：
He bought a house.I've been to the house.
他买了幢房子。我去过那幢房子。
3)指世上独一物二的事物：
the sun， the sky， the moon， the earth
4)单数名词连用表示一类事物，如：the dollar 美元;
the fox 狐狸;或与形容词或分词连用，表示一类人：the rich 富人; the living 生者。
5)用在序数词和形容词最高级，及形容词only， very， same等前面：
Where do you live?I live on the second floor. 你住在哪?我住在二层。
That's the very thing I've been looking for. 那正是我要找的东西。
6)与复数名词连用，指整个群体：
They are the teachers of this school.指全体教师)
They are teachers of this school. (指部分教师)
7)表示所有，相当于物主代词，用在表示身体部位的名词前：
She caught me by the arm..她抓住了我的手臂。
8)用在某些由普通名词构成的国家名称、机关团体、阶级、等专有名词前：
the People's Republic of China 中华人民共和国
the United States 美国
9)用在表示乐器的名词之前： She plays the piano.她会弹钢琴。
10) 用在姓氏的复数名词之前，表示一家人：
the Greens 格林一家人 (或格林夫妇)
11) 用在惯用语中：
in the day, in the morning (afternoon，evening),the day after tomorrow
the day before yesterday,the next morning,
in the sky (water，field，country)
in the dark,in the rain,in the distance,
in the middle (of),in the end,
on the whole,by the way,go to the theatre

有关大学英语四级常用的语法精选
Ⅴ 连词
并列连词
表示意义的引申: and, both…and, not only…but(also), as well as, and …as well, neither…nor
表示选择: or, either…or
表示转折: but, while, whereas, yet, however/nevertheless(也可认为是副词)
表示因果: for, so, therefore, hence
从属连词

表示原因: because, as, since, now that, seeing that
表示条件: if, unless, in case, provided(that), suppose, as long as, on condition (that),
表示其他关系: (al)though, than, as/so…as, lest, in order that, so…that
Ⅵ 定语从句
限制和非限制性定语从句: 限制性定语从句是名词词组不可缺少的一个组成部分, 去掉了会造成病句或意义不明确; 非限制性定语从句属于补充说明性质, 去掉了不会影响主要意义, 通常用逗号与它的先行词分开.
The boys who wanted to play football were disappointed when it rained.
The boys, who wanted to play football, were disappointed when it rained.
如果定语从句的先行词是专有名词, 或是带有形容词性物主代词(my, his, etc)或形容词性指示代词(this, that, etc)作限定词, 其后的定语从句通常都是非限制性的:
Mary Smith, who is in the corner, wants to meet you.
Her mother, who had long suffered form arthritis, died last night.
All these books, which have been donated by visiting professors, are to be used by the postgraduates.
在非限制性定语从句中只能用who/whom指人, 用which指物,通常不用that替代.
My father, who had been on a visit to America, returned yesterday.
All the books, which had pictures in them, were sent to the little girl.
定语从句的引导词
that, who, whom: 非限制性定语从句, 如果修饰人, 一般用who, 有时用that (作主语时用who较多). 如果关系代词在从句中作宾语, 就应当用宾格 whom 或that, 但在大多数情况下都可以省略掉, 在口语中可用who代替whom.
Here is the man (whom) you've been looking for.
He is a man (that) you can safely depend on.
The people (who/that) you were talking to were Swedes.
There are some people here who I want you to meet.
但在介词后只能用whom:
This is the man to whom I referred.
但在口语中一般都把介词放到句子后面去, 这时可用that, 但省略时更多一些.
Have you met the person about whom he was speaking?
Have you met the person (that) he was speaking about
The girl to whom I spoke is my cousin.
The girl (who/that) I spoke to is my cousin.
限制性定语从句如果修饰“物”, 用关系代词that的时候较多, 也有时用which.. 当这个代词在从句中是用作宾语时, 在绝大多数情况下都是省略的, 特别是口语中(尤其是当被修饰的词是all, everything等词时):
Have you everything you need?
(Is there) anything I can do for you?
All you have to do is to press the button.

短语部分没有独立主语，则短语结构称为非谓语动词。
非谓语动词的结构：分词(分词短语)
句子的主语决定非谓语动词中的分词是用主动还是被动形式。如果是句子的主语发出动作，则使用现在分词;如果动作不是由句子的主语发出，则使用过去分词。

一些特殊的动词：
第一点：forget 忘记; [反义] remember 记得;
这两个词后加动词不定式表示将要进行的行为;这两个词后加动词ing形式表示已经做过的事情。
注意：动名词与现在分词形式一样，但含义不同。这两个词后加动词ing形式都是动名词。
forget to do sth. 忘记要去做某事; forget doing sth. 忘记做过某事;
remember to do sth. 记得要去做某事; remember doing sth. 记得做过某事;
2. I remember _B_ to help us if we ever got into trouble.

非谓语动词与独立主格：短语，句子(或者句子，短语)
当短语部分有独立主语，并且该主语不同于句子主语，这时短语结构称为独立主格。(它最明显的特点是短语部分有独立的主语)。
独立主格的结构1：名词(代词)+ 分词 [现在分词、过去分词]
现在分词表示主动的，正在进行的行为;过去分词表示被动的，已经完成的行为。 作题时要通过判断动作与名词(代词)之间的关系来确定是使用现在分词还是过去分词。当动作由名词(代词)发出时使用现在分词，而名词(代词)是受动者时则用过去分词。
1. Silver is the best conductor of electricity， copper _B_ it closely.
A followed B following C to follow D being followed
2. All things _A_， the planned trip will have to be called off.
A considered B be considered C considering D having considered
call off 取消; cancel vt. 取消; 四级中的考点就是现在分词和过去分词的区别。
独立主格的结构2：with + 名词(代词)+ 分词 [句子当中作状语]
3. After the Arab states won independence， great emphasis was laid on expanding education， with girls as well as boys _C_ to go to school.
A to be encouraged B been encouraged C being encouraged D be encouraged
as well as 和(相当于and); be encouraged不会考。
动词不定式有预示将来行为的含义。to be encouraged 将要被鼓励;
been encouraged 已经被鼓励完了，与主句的谓语动词相对;being encouraged 正在被鼓励
短语部分没有独立主语，则短语结构称为非谓语动词。
非谓语动词的结构：分词(分词短语)
句子的主语决定非谓语动词中的分词是用主动还是被动形式。如果是句子的主语发出动作，则使用现在分词;如果动作不是由句子的主语发出，则使用过去分词。
1.No matter how frequently _A_， the works of Beethoven always attract large audiences.
A performed B performing C to be performed D being performed
perform vt. 表演，演出，演奏;
to be performed 将要被演奏; being performed 正在被演奏;

这两个词后加动词不定式表示将要进行的行为;这两个词后加动词ing形式表示已经做过的事情。

forget to do sth. 忘记要去做某事; forget doing sth. 忘记做过某事;
remember to do sth. 记得要去做某事; remember doing sth. 记得做过某事;
2. I remember _B_ to help us if we ever got into trouble.
