热点语法
主谓一致用法难点小结：
一、集合名词作主语时的主谓一致。
1. 集合名词有family, team, group, party, class, public, club, crew, crowd, enemy, audience, company, committee, government, population等，当被看作一个整体时，表示单数意义，谓语动词用单数形式；如果这些集合名词指其中的每个成员，表示复数意义，谓语动词则用复数形式。即谓语动词的单复数要与主语的含义相一致。如：
My class is a big one, including thirty boys and thirty girls.
My class are working hard for the coming exam.
2. 有些集合名词作主语时，谓语只能用复数形式，如：people, the police, the military, mankind, cattle等。如：
The police are searching for the lost child.
二、不定代词作主语时的主谓一致。
不定代词anyone, anybody, anything, everyone, everybody, everything, someone, somebody, no one, nobody, nothing, each, the other等作主语时，谓语动词用单数。如：
Everything goes well with me.
Each of the students in our class has an English-Chinese dictionary.
三、“名词＋名词”作主语时的主谓一致。
当表示同一人物或观点时，谓语动词用单数。如：A novelist and playwright is coming to our school. 这里表示“一位小说家兼剧作家”，是同一个人，所以谓语动词用单数。
如果是A novelist and a playwright作主语，这时表示“一位小说家和一位剧作家”，是两个人，所以谓语动词用复数，该句应改为：A novelist and a playwright are coming to our school.
四、The ＋ adj.作主语时的主谓一致。
当The ＋ adj.表示抽象的含义时，谓语动词用单数。如：The beautiful is the true.
当The ＋ adj.表示该类全体的含义时，谓语动词用复数。如：The rich should help the poor.

语法剖析（主谓一致）
主谓一致，指人称和数方面的一致关系。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.
为人民服务是我最大的幸福.
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.
Every boy and every girl likes to go swimming. 每个男孩和每个女孩都喜欢去游泳.
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:
His clothes are good. 但这些名词前若出现 a pair of , 谓语一般用单数.如:
A pair of glasses is on the desk. 桌上有一副眼镜。
9. 形复意单名词如:news ; 以ics 结尾的学科名称如: physics, mathematics, economics; 国名如: the United States; 报纸名如: the New Times; 书名如: Arabian Night <天方夜谈>; 以及The United Nations<联合国> 等作主语时, 谓语动词用单数。
10. “a +名词+and a half “, “one and a half + 名词”, “the number of + 名词” 等作主语时, 谓语动词要用单数. 如:
Only one and a half apples is left on the table.
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:
The rest of the bikes are on sale today. 剩下的自行车， 今天出售。
60%of the apple was eaten by little boy. 这个苹果的60%都被这个小男孩吃了。
Most of the apples were rotten. 大部分的苹果都是烂的。
Most of the apple was eaten by a rat. 这个苹果的大部分被老鼠吃了。
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:
Fifteen minus five is ten . 15减去5等于10。
4. 表示时间, 金钱, 距离, 度量等的名词做主语时, 尽管是复数形式, 它们做为一个单一的概念时, 其谓语动词用单数.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. 玛丽是唯一一个饲养宠物的人。

（-ing动词短语作原因状语）

语法剖析（非谓语动词---动词的-ing形式作主语和宾语）
一、动词-ing形式作主语
● 动词-ing形式作主语常用来表示经常性和习惯性的动作。动词-ing形式作主语通常放在句首，谓语用单数形式。例如：Listening to music is my sister’s hobby.
● 动词-ing形式作主语时，为了保持句子平衡，可以用it作形式主语。常用的结构：
1. It is + no use / no good / useless etc.+ v-ing
2. It is + nice / good / interesting / a waste of … etc. + v-ing 例如：
It is no use crying over spilt milk.
二、动词-ing形式作宾语
● 动词-ing形式既可作动词的宾语，又可作介词的宾语。
1. 以下动词或短语只接动词-ing形式作宾语：
admit, avoid, appreciate, consider, enjoy, escape, finish, keep, mind, miss, suggest等动词; can’t stand, give up, feel like, keep on, think of, set about, dream of 等短语。
2. 在下列短语中，to是介词，后面应用动词-ing形式作宾语：
be / get used to, look forward to, devote…to, pay attention to, object to等。
3. 下列动词或短语既可以跟动词-ing形式作宾语，也可以跟不定式作宾语，但意义上有区别：
● like, love, prefer如表示经常性的行为后接动词-ing形式；如表示具体的行为常用动词不定式，但要注意：如果like, love, prefer前有would，后面则接动词不定式。如：Would you like to go shopping with me?
● 下列几组词接动词-ing形式作宾语和不定式作宾语含义不同：
forget doing 忘记已做过某事； forget to do 忘记要做某事
remember doing 记得做过某事； remember to do 记住要做某事
mean doing 意思是，意味着； mean to do 打算做
regret doing 后悔做过某事; regret to do 遗憾要做某事
can’t help doing 禁不住做； can’t help (to) do 不能帮忙做。
● 在allow, permit, advise等动词后直接跟动词-ing形式作宾语，如果这些词后面有名词或代词作宾语，其后要用动词不定式作宾语补足语。如：
We don’t allow smoking in the classroom.
We don’t allow students to smoke.
● 动词need, require, want作“需要”解时，其后用动词-ing的主动形式或不定式的被动形式作宾语，这时动词-ing的主动形式表被动意义。如：
Your coat wants washing. = Your coat wants to be washed.
三、动词-ing的复合结构
动词-ing的复合结构即：物主代词或名词所有格(作宾语时也可以用代词宾格或名词普通格) + 动词-ing。如：
Lucy’s turning up surprised everyone present.
Would you mind my / me using your mobile phone?
四、动词-ing的时态、语态以及否定形式动词-ing有一般式(doing) 和完成式 (having done) 两种时态，一般式的被动语态是being done，完成式的被动语态是having been done。动词-ing的完成式所表示的动作发生在谓语动词的动作之前。
动词-ing的否定形式是在doing之前加not。例如：
I’m sorry for not having told you the news earlier.

㈥ 外研社高一英语必修3知识点

一. 直接引语和间接引语

（一）直接引述别人的原话，叫做直接引语；用自己话转述别人的话，叫做间接引语。间接引语一般构成宾语从句。直接引语必须放在引号内，间接引语则不用引号。直接引语改为间接引语时，除将引语部分变成宾语从句外，还必须对直接引语中的人称、时态、指示代词、时间状语、地点状语等进行改变。

1. 时态的变化：直接引语变为间接引语时，通常受转述动词said, asked等的影响而使用过去化的时态，即把原来的时态向过去推，也就是一般现在时变为一般过去时，现在进行时变为过去进行时，等等。例如：
Tom said to me,“My brother is doing his homework.”
→Tom said to me that his brother was doing his homework.

2. 人称代词、指示代词、时间状语、地点状语等等的变化： 根据意义进行相应的变化，例如：
She asked Jack,“Where have you been?”
→She asked Jack where he had been.

He said,“These books are mine.”
→He said that those books were his.

（二）直接引语改为间接引语时，都使用陈述语序，但是因为原句的句式不同，所以变成间接引语时所用的连词会有所不同。直接引语如果是一般疑问句，用连接词whether或if；如果是特殊疑问句，则用疑问词引导间接引语。转述的动词一般用asked，可以在其后加上一个间接宾语me, him, her, us等。如：
She said,“Is your father at home?”
→She asked me if/whether my father was at home.

“What do you do every Sunday?”My friend asked me.
→My friend asked me what I did every Sunday.

直接引语如果是祈使句，改为间接引语时，要将祈使句的动词原形变为带to的不定式，并在不定式的前面根据原句的语气（即请求或命令）加上ask, tell, order等动词，如果祈使句为否定式，则在不定式前加not。其句型为：ask / tell / order someone (not) to do something. 例如：
She said to us,“Please sit down.”
→She asked us to sit down.

He said to him,“Go away!”
→He ordered him to go away.

He said, “Don’t make so much noise, boys.”
→He told the boys not to make so much noise.

二. 各种时态的被动语态
被动语态概述
被动语态的概念：它是动词的一种形式，表示主语与谓语之间的执行或被执行关系。主动语态表示主语是谓语动作的执行者，例如：They saw the little boy crying by the river. 被动语态表示主语是谓语动作的承受者，例如：The little boy was seen crying by the river.

被动语态的构成
被动语态的形式是由“助动词be+动词的过去分词”构成。助动词be随着主语的人称、数、时态等的不同而变化。几种常见时态的被动语态形式如下：
1. 一般现在时 am/is/are + 过去分词
例如：Rice is planted in the south of China.

2. 一般过去时 was/were + 过去分词
例如：These trees were planted the year before last.

3. 一般将来时 will/shall + be + 过去分词
例如：A sports meeting will be held next week in our school.

4. 现在进行时 am/is/are + being + 过去分词
例如：Your radio is being repaired now.

5. 过去进行时 was/were + being + 过去分词
When he got there, the problem was being discussed.

6. 现在完成时 have/has + been + 过去分词
His work has been finished.
Has his work been finished? Yes, it has. / No, it hasn’t.

7. 过去完成时 had + been + 过去分词
注意：
1．除了be之外的其它系动词如get, stay等也可以和过去分词构成被动语态。例如：Their questions haven’t got answered.

2. 含有情态动词的谓语变成被动语态使用“情态动词+ be + 过去分词”结构。例如：
More attention should be paid to the old in this country.
This work can’t be done until Mr. Black comes.

3. 含有“be going to”, “be to”等结构的谓语，其被动语态分别用“be going to + be + 过去分词”和“be to + be + 过去分词”。例如：
The problem is going to be discussed at the next meeting.
All these books are to be taken to the library.

4. 被动语态与系表结构的区别：“连系动词+用作表语的过去分词”构成的系表结构，与被动语态的形式完全一样，所以应注意它们的区别。被动语态中的过去分词是动词，多强调动作；系表结构中的过去分词相当于形容词，多强调状态。前者通常可用by 引出动作的执行者，而后者则不可以。例如：
The map was changed by someone.（被动结构）
That custom remained unchanged for many centuries.（系表结构）
系表结构中的过去分词通常可被very修饰，被动语态中的过去分词往往要用much修饰。
例如：
He was very excited.（系表结构）
He was much excited by her words.（被动结构）

5. 主动形式表被动意义。有些动词的主动形式有被动意味，如 open, read, sell, shut, wash, wear, write等。此时句子的主语一般是物。例如：
These books sell well. 这些书很畅销。
The door won’t shut. 这门关不上。
The clothes wash well. 这些衣服很好洗。

高一英语外研版必修四第四单元cultural corner原文及翻译:

Rockets
Todayrockets are very advanced machines which we can use to send astronauts intospace. They are also used in firework displays to celebrate great events, suchas the end of the Olympic Games or the beginning of the new millennium inthe year 2000.
Rocketswere probably invented by accident about 2,000 years ago. The Chinese had aform of gunpowderwhich was put in bamboo tubes and thrown into fires to make explosions ringfestivals. Perhaps some of the tubes jumped out of the fireinstead of exploding in it. The Chinese discovered that the gas escaping fromthe tube could lift it into the air. The idea of the rocket wasborn.
Thefirst military use of rockets was in 1232. The Song Dynasty was at war with theMongols. During the battle of Kaifeng, the Song army shot "arrows offlying fire".The tubes were attached to a long stick which helped keep the rocketmoving in a straightdirection. Soon the Mongols learned how to make rockets themselves and it ispossible that they introced them to Europe. Between the 13th and 15thcenturies there were many rocketexperiments in England, France and Italy. They were used for military purposes.One Italian scientist even invented a rocketwhich could travel over the surface ofwater and hit an enemy ship.
But not everybody wanted to use rocketsin battles. Wan Hu, a Chinese government official, invented a flying chair. Heattached two big kites to the chair, and 47 rockets to the kites. The rocketswere lit, there was a huge explosion andclouds of thick smoke. When the smoke cleared Wan Hu and his chair haddisappeared. No one knows what happened. Did Wan Hu die in the explosion? Orwas he carried miles into space, becoming the world's first astronaut?
火箭
今天，火箭是我们用来将宇航员送入太空的非常先进的机器。它们也被用在庆祝重大事件的焰火表演中，像奥运会的闭幕式或2000年新千年的开始。
火箭很可能是在大约两千年前被偶然发明出来的。中国人有一种装在竹管里的火药，这种火药是节日中被用来扔进火里爆炸的。也许一些竹管从火堆里蹿了出来，而不是在里面炸开。中国人发现从竹管里释放出来的气体可以使其飞向空中。于是关于火箭的想法诞生了。
火箭第一次被用于军事上是在1232年。那时宋朝正与蒙古作战。在开封战役中，宋军射出了“飞火箭”。这些竹管被绑到一根长棍上，这根长棍可帮助火箭沿笔直的方向飞行。不久，蒙古人学会了怎样自己制造火箭，并且可能是他们将其引入欧洲的。在13世纪到15世纪期间，在英国、法国和意大利有很多关于火箭的实验。它们都用于军事目的。一个意大利科学家甚至发明了一种可以飞过水面打中敌舰的火箭。
但并不是每个人都想将火箭用于战争。一个名叫万户的中国官员发明了一种“飞椅”。他把两个大风筝绑到椅子上，又把47个火箭绑在风筝上。火箭被点燃了，发生了巨大的爆炸，出现了厚厚的浓烟。当烟雾消散时，万户和他的椅子已经不见了。没有人知道发生了什么。万户被炸死了？还是他被载入了数英里远的太空而成为世界上第一个宇航员了呢？

亚洲的沙尘暴
几百年以来,沙尘暴一直是许多亚洲国家面临的主要灾难.科学家尝试过多种方法解决这个问题,在中国,也发动了群众运动来对付沙尘暴.
沙尘暴是夹带沙尘的强烈而干燥的风.沙尘暴夹带的沙尘含量常常很大,以致于可以遮天蔽日.风力强大时可以搬动沙丘.世界上沙尘暴发生的四个主要地区是中亚、北美、中非和澳大利亚.来自内蒙的任建波是这样来描述他小时候遭遇的一次沙尘暴的：
“遇上沙尘暴是一种可怕的经历,”他说,“你一点办法也没有.那是我遭遇过的最可怕、最危险的境况.你只能祈求会活下来.那时候我觉得我会消失在沙尘下.”
中国的西北地区是中亚沙尘暴中心的一部分.沙尘暴发端于沙漠地区.因“荒漠化”越发严重,中国近年来发生沙尘暴的次数明显增加了.这是由于气候变化和人们伐树挖草,使土地变成荒漠后产生的一种作用.
沙尘暴有时候会影响北京.居民醒来时,看到昏黄的天空,狂风夹着黄沙在城里肆虐.暴风有时持续一整天,车辆开得很慢,因为浓浓的尘埃降低了能见度.
中国中央气象站能在沙尘暴到达北京前几周预报沙尘暴,但沙尘暴的力量有时很惊人.沙尘暴到来时,气象专家建议人们不要外出.家住北京的黄小梅说：“在沙尘暴中骑车真可怕.风力很强,呼吸困难,沙尘使人难受.所以不要出门,最好带上口罩.”
沙漠离北京西境只有250公里.为阻止沙漠的逼近,政府已经开始植树.政府已经种了300亿棵树,并准备在未来的五年里继续种植.

祝你开心如意！
