高三英语期末考试必考知识点概括1
疑问代词概说
"疑问代词有who(谁，主格)，whom(谁，宾格)，whose(谁的，所有格)，what(什么)和which(哪个，哪些)等。
疑问代词用于特殊疑问句中
疑问代词一般都放在句首，并在句中作为某一句子成分。如：
Who is going to speak to us tomorrow?明天谁来跟我们讲话?(who作主语)
Who told you so?是谁告诉你的?(who作主语)
Whom are you talking about ?你们在说谁?(whom作宾语，但在句首时口语常用who代替whom)
Whose umbrella is this ?这是谁的伞?(whose作定语)
What is that? 那是什么?(what作表语)
What did he say?他说什么?(what作宾语)
Which is yours，the blue pen or the redone?蓝笔和红笔哪一支是你的?(which作主语)
[注一]关于疑问代词的各种用法，可参看77.70-77.72。
[注二]疑问代词who，what，which等后面加单词ever，可强调语气，表达说话人的各种感情。如：
What ever do you want?你到底想要什么?
Who ever is she looking for ?她究竟是在找谁?
[注三]which表示在一定范围之内的选择，what则没有这种限制。如：
What do you usually have for lunch?你们午饭通常吃些什么?
Which do you like best?你最喜欢哪一个?
Which of you comrades come from the Northeast? 你们同志们中间谁是东北人?
疑问代词可以引导一个间接疑问句
间接疑问句在句中可用作主语、宾语、表语等。疑问代词本身在间接疑问句中又担任一定的句子成分。如：
Who will be in charge of the work is still not decided.谁将负责这项工作，现在还没有决定。(疑问代词who引导一个主语从句，它本身又在从句中用作主语。)
Do you know what his name is?你知道他叫什么名字吗?(疑问代词what引导一个宾语从句，而它本身又在从句中用作表语。)
[注一] what所引导的名词性从句(即主语从句、宾语从句、表语从句) 有时不是间接疑问句。如：
What he says is quite true.他所讲的话很对。(what相当于that which。它引导一个主语从句，这个从句不是间接疑问句。)
Children do what the nurse tells them to do.保育员让孩子干什么他们就做什么。(what引导一个宾语从句，这个从句也不是间接疑问句。)
[注二] whatever，whoever，whichever等词可引导名词性从句。这些名词性从句也不是间接疑问句。whatever，whoever，whichever也可引导表示让步的状语从句。见15.65和15.72)如：
They eat whatever they can find.他们找到什么就吃什么。(whatever引导一个宾语从句，并在从句中作宾语。)
I've got plenty of books 1eft.Whoever wants an extra copy can get one from me.我还剩下许多书，谁还想再要一本可来拿。(whoever引导一个主语从句，并在从句中作主语。)

主谓一致(Subject- Verb Agreement)，指”人称”和”数方面的一致关系.如: He is going abroad. They are playing football. 可分为:语法一致, 内容一致, 就近一致.
(一) 语法一致原则: 即主语为单数,谓语用单数,主语为复数,谓语也用复数. 以下为注意事项:
1. 单数主语即使后面带有with , along with, together with, like(象), but (除了),except, besides, as well as, no less than, rather than(而不是), including, in addition to 引导的短语, 谓语动词仍用单数.
如: Air as well as water is matter. 空气和水都是物质.
No one except two servants was late for the dinner. 除了两个仆人外, 没有一个人迟来用餐。
2. 用and连接的并列主语,如果主语是同一个人,同一事,同一概念, 谓语动词用单数, 否则用复数. 如:
The poet and writer has come. 那位诗人兼作家来了.(一个人)
A hammer and a saw are useful tools. 锤子和锯都是有用的工具. (两样物)
用and连接的成对名词习惯上被看成是一个整体, 如:bread and butter(黄油抹面包), knife and fork(刀叉)等作主语时, 谓语动词用单数。
3. 不定式(短语), 动名词(短语), 或从句作主语时, 谓语动词用单数. 如:
Serving the people is my great happiness.
为人民服务是我的幸福.
When we’ll go out for an outing has been decided.
我们什么时候出去郊游已决定了。
4. 用连接的并列主语被each, every 或no修饰时, 谓语动词用单数.

No teacher and no student was absent from the meeting. 没有老师也没有学生开会缺席.
Each man and (each) woman is asked to help. 每个男人和每个女人都被请去帮忙。
5. each of + 复数代词, 谓语动词用单数. 复数代词+each, 谓语动词用单数.如:
Each of us has something to say. 我们每个人都有话要说。
6. 若主语中有more than one 或many a/an , 尽管从意义上看是复数, 但它的谓语动词仍用单数。 但more+复数名词+than one做主语时, 谓语动词仍用复数. 如:
Many a boy likes playing basketball. 许多男生都喜欢打篮球.
More than one student was late. 不只一个学生迟到
More persons than one come to help us. 不止一个人来帮助我们。
7. none 做主语时,谓语动词可用单数, 也可用复数; 但在代表不可数的东西时总是看作单数,因而谓语动词要用单数. 如:
None of us are (is) perfect. 人无完人。
None of this worries me. 这事一点不使我着急。
8. 名词如: trousers, scissors, clothes, goods, glasses 等作主语时, 谓语动词必须用复数. 如:

注意: one or two + 复数名词作主语, 谓语动词用复数形式, 如:
One or two places have been visited. 参观了一两个地点。(二) 内容一致原则:
1.主语中有all, half, most, the rest等, 以及”分数或百分数+名词”做主语时,谓语动词单复数取决于连用的名词.如:

2. 不定数量的词组, 如:part of , a lot of , lots of , one of , a number of , plenty of等作主语时, 谓语动词的单复数取决于量词后面名词的数.如:
A part of the textbooks have arrived. 一小部分教科书已运到。
A part of the apple has been eaten up by the pig. 这个苹果的一部分被猪吃光了。
3. 加减乘除用单数.如:

The committee has/have decided to dismiss him. 委员会决定解雇他。
6. the +形容词/过去分词形式”表示一类人或事物, 作主语时, 谓语动词用复数.如:
The injured were saved after the fire.
(三) 就近原则
1. 由here, there, where 等引导的倒装句中, (有时主语不止一个时)谓语动词与靠近它的主语在数上一致.如:
Here comes the bus 公共汽车来了.
Here is a pen and some pieces of paper for you. 给你一支钢笔和几张纸。
Where is your wife and children to stay while you are away?
你不在这儿的时候, 你爱人和孩子在哪儿呆呢?
2. 用连词or, either.... or, neither….nor, not only….but also 等连接的并列主语, 谓语动词与靠近它的主语在数上一致。 如：
Neither the students nor the teacher knows anything about it 学生和老师都不知道这事.
He or you have taken my pen. 他或你拿了我的钢笔。
注意: one of +复数名词+who/that/which 引导的定语从句中, 定语从句的动词为复数。如：
Mary is one of those people who keep pets. 玛丽是饲养宠物者之一。
The only one of +复数名词+ who/that./which 引导的定语从句中，定语从句的动词应为单数。
Mary is the only one of those people who keeps pets. 玛丽是一个饲养宠物的人。

1. 分词或分词短语作状语时，可以表示时间、原因、让步、条件，方式或伴随状况。通常可转换成相应的状语从句;表示方式或伴随状况时可以转换成并列句或非限制性定语从句。例如：
Put into use in April 2000 (=When it was put into use in April 2000), the hotline was meant for residents reporting water and heating supply breakdowns. 分词短语作时间状语
Blamed for the breakdown of the school computer network (=Because she was blamed for the breakdown of the school computer network), Alice was in low spirits. 分词短语作原因状语
Given time (=If he is given time), he’ll make a fist-class tennis player. 分词短语作条件状语
We often provide our children with toys, footballs or basketballs, thinking that all children like these things. (= and think that all children like these things.) 分词短语作伴随状语
2. 有时为了强调，分词前可带when, while, if, though, as if, unless等连词一起作状语，以便使句子的意思更清楚、更连贯。例如：
When comparing different cultures, we often pay attention only to the differences without noticing the many similarities.
Though tired, he still continued reading.
3. 现在分词和过去分词作状语时的用法比较。
不管是现在分词还是过去分词单独作状语，其逻辑主语必须与主句的主语一致。分词作状语通常可转换成一个相应的状语从句或并列句，如果状语分句或并列句中的谓语动词为被动结构，就用过去分词;如果状语分句或并列句中的谓语动词为主动结构，就用现在分词。例如：
When compared with the size of the whole earth , the biggest ocean does not seem big at all.
分词部分相当于When the biggest ocean is compared with the size of the whole earth, 主语与分词是被动关系，所以用过去分词。
When comparing it with the size of the whole earth, we find that the biggest ocean does not seem big at all.
When we compare it with the size of the whole earth... 主语与分词是主动关系, 所以用现在分词。
Faced with a bill for$10,000(=Because he is faced with a bill for$10,000), John has taken an extra job.
Whenever he was asked why he was late for class, he would answer carelessly, always saying the same thing (= and he would say the same thing).
注意：
1. 现在分词有两种时态：一般式doing和完成式having done。一般式通常表示与主句的谓语动词所表示的动作同时发生或无先后;完成式则强调分词所表示的动作先于谓语动词所表示的动作。如：
While walking in the street, we met some friends of ours.(同时发生)
Having waited in the queue for half an hour, Tom suddenly realized that he had left his wallet at home. (“等待”先于谓语动词“意识到”)
2. 分词的否定式的构成: not +分词。 Not having received a reply, he decided to write again.
