熱點語法
主謂一致用法難點小結:
一、集合名詞作主語時的主謂一致。
1. 集合名詞有family, team, group, party, class, public, club, crew, crowd, enemy, audience, company, committee, government, population等,當被看作一個整體時,表示單數意義,謂語動詞用單數形式;如果這些集合名詞指其中的每個成員,表示復數意義,謂語動詞則用復數形式。即謂語動詞的單復數要與主語的含義相一致。如:
My class is a big one, including thirty boys and thirty girls.
My class are working hard for the coming exam.
2. 有些集合名詞作主語時,謂語只能用復數形式,如:people, the police, the military, mankind, cattle等。如:
The police are searching for the lost child.
二、不定代詞作主語時的主謂一致。
不定代詞anyone, anybody, anything, everyone, everybody, everything, someone, somebody, no one, nobody, nothing, each, the other等作主語時,謂語動詞用單數。如:
Everything goes well with me.
Each of the students in our class has an English-Chinese dictionary.
三、「名詞+名詞」作主語時的主謂一致。
當表示同一人物或觀點時,謂語動詞用單數。如:A novelist and playwright is coming to our school. 這里表示「一位小說家兼劇作家」,是同一個人,所以謂語動詞用單數。
如果是A novelist and a playwright作主語,這時表示「一位小說家和一位劇作家」,是兩個人,所以謂語動詞用復數,該句應改為:A novelist and a playwright are coming to our school.
四、The + adj.作主語時的主謂一致。
當The + adj.表示抽象的含義時,謂語動詞用單數。如:The beautiful is the true.
當The + adj.表示該類全體的含義時,謂語動詞用復數。如:The rich should help the poor.

5.What made her succeed later on was the kindness and consideration she showed to all her patients

(What made her succeed主語從句。了解what引導的名詞性從句的譯法,明白它們在句中的成分:作主語、賓語、表語、同位語)
語法剖析(主謂一致)
主謂一致,指人稱和數方面的一致關系。分為:語法一致, 內容一致, 就近一致。
(一) 語法一致原則: 即主語為單數,謂語用單數,主語為復數,謂語也用復數。以下為注意事項:
1. 單數主語即使後面帶有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 引導的短語, 謂語動詞仍用單數。如: Air as well as water is matter. 空氣和水都是物質。No one except two servants was late for the dinner. 除了兩個僕人外, 沒有一個人遲來用餐。
2. 用and連接的並列主語,如果主語是同一個人,同一事,同一概念, 謂語動詞用單數, 否則用復數。如:
The poet and writer has come. 那位詩人兼作家來了.(一個人)
A hammer and a saw are useful tools. 錘子和鋸都是有用的工具. (兩樣物)
用and連接的成對名詞習慣上被看成是一個整體, 如:bread and butter(黃油抹麵包), knife and fork(刀叉)等作主語時, 謂語動詞用單數。
3. 不定式(短語), 動名詞(短語), 或從句作主語時, 謂語動詞用單數. 如:
Serving the people is my great happiness.
為人民服務是我最大的幸福.
When we』ll go out for an outing has been decided.
我們什麼時候出去郊遊已決定了。
4. 用連接的並列主語被each, every 或no修飾時, 謂語動詞用單數.
Every boy and every girl likes to go swimming. 每個男孩和每個女孩都喜歡去游泳.
No teacher and no student was absent from the meeting. 沒有老師也沒有學生開會缺席.
Each man and (each) woman is asked to help. 每個男人和每個女人都被請去幫忙。
5. each of + 復數代詞, 謂語動詞用單數. 復數代詞+each, 謂語動詞用單數.如:
Each of us has something to say. 我們每個人都有話要說。
6. 若主語中有more than one 或many a/an , 盡管從意義上看是復數, 但它的謂語動詞仍用單數。 但more+復數名詞+than one做主語時, 謂語動詞仍用復數. 如:
Many a boy likes playing basketball. 許多男生都喜歡打籃球.
More than one student was late. 不只一個學生遲到
More persons than one come to help us. 不止一個人來幫助我們。
7. none 做主語時,謂語動詞可用單數, 也可用復數; 但在代表不可數的東西時總是看作單數,因而謂語動詞要用單數. 如:
None of us are (is) perfect. 人無完人。
None of this worries me. 這事一點不使我著急。
8. 名詞如: trousers, scissors, clothes, goods, glasses 等作主語時, 謂語動詞必須用復數. 如:
His clothes are good. 但這些名詞前若出現 a pair of , 謂語一般用單數.如:
A pair of glasses is on the desk. 桌上有一副眼鏡。
9. 形復意單名詞如:news ; 以ics 結尾的學科名稱如: physics, mathematics, economics; 國名如: the United States; 報紙名如: the New Times; 書名如: Arabian Night <天方夜談>; 以及The United Nations<聯合國> 等作主語時, 謂語動詞用單數。
10. 「a +名詞+and a half 「, 「one and a half + 名詞」, 「the number of + 名詞」 等作主語時, 謂語動詞要用單數. 如:
Only one and a half apples is left on the table.
注意: one or two + 復數名詞作主語, 謂語動詞用復數形式, 如:
One or two places have been visited. 參觀了一兩個地點。
(二) 內容一致原則:
1.主語中有all, half, most, the rest等, 以及」分數或百分數+名詞」做主語時,謂語動詞單復數取決於連用的名詞.如:
The rest of the bikes are on sale today. 剩下的自行車, 今天出售。
60%of the apple was eaten by little boy. 這個蘋果的60%都被這個小男孩吃了。
Most of the apples were rotten. 大部分的蘋果都是爛的。
Most of the apple was eaten by a rat. 這個蘋果的大部分被老鼠吃了。
2. 不定數量的片語, 如:part of , a lot of , lots of , one of , a number of , plenty of等作主語時, 謂語動詞的單復數取決於量詞後面名詞的數.如:
A part of the textbooks have arrived. 一小部分教科書已運到。
A part of the apple has been eaten up by the pig. 這個蘋果的一部分被豬吃光了。
3. 加減乘除用單數.如:
Fifteen minus five is ten . 15減去5等於10。
4. 表示時間, 金錢, 距離, 度量等的名詞做主語時, 盡管是復數形式, 它們做為一個單一的概念時, 其謂語動詞用單數.如:
Ten miles is a good distance. 十英里是一個相當的距離。
5. (1) 通常作復數的集體名詞. 包括police , people, cattle 等, 這些集體名詞通常用作復數.如:
The British police have only very limited powers.
(2) 通常作不可數名詞的集體名詞. 包括equipment, furniture, clothing, luggage 等.
(3) 可作單數也可作復數的集體名詞. 包括 audience, committee, government, family, enemy, group, party, team, public 等.如:
The committee has/have decided to dismiss him. 委員會決定解僱他。
6. the +形容詞/過去分詞形式」表示一類人或事物, 作主語時, 謂語動詞用復數.如:
The injured were saved after the fire.
(三) 就近原則
1. 由here, there, where 等引導的倒裝句中, (有時主語不止一個時)謂語動詞與靠近它的主語在數上一致.如:
Here comes the bus 公共汽車來了.
Here is a pen and some pieces of paper for you. 給你一支鋼筆和幾張紙。
Where is your wife and children to stay while you are away?
你不在這兒的時候, 你愛人和孩子在哪兒呆呢?
2. 用連詞or, either.... or, neither….nor, not only….but also 等連接的並列主語, 謂語動詞與靠近它的主語在數上一致。 如:
Neither the students nor the teacher knows anything about it 學生和老師都不知道這事.
He or you have taken my pen. 他或你拿了我的鋼筆。
注意: one of +復數名詞+who/that/which 引導的定語從句中, 定語從句的動詞為復數。如:
Mary is one of those people who keep pets. 瑪麗是飼養寵物者之一。
The only one of +復數名詞+ who/that./which 引導的定語從句中,定語從句的動詞應為單數。
Mary is the only one of those people who keeps pets. 瑪麗是唯一一個飼養寵物的人。

(-ing動詞短語作原因狀語)
語法剖析(非謂語動詞---動詞的-ing形式作主語和賓語)
一、動詞-ing形式作主語
● 動詞-ing形式作主語常用來表示經常性和習慣性的動作。動詞-ing形式作主語通常放在句首,謂語用單數形式。例如:Listening to music is my sister』s hobby.
● 動詞-ing形式作主語時,為了保持句子平衡,可以用it作形式主語。常用的結構:
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、動詞-ing形式作賓語
● 動詞-ing形式既可作動詞的賓語,又可作介詞的賓語。
1. 以下動詞或短語只接動詞-ing形式作賓語:
admit, avoid, appreciate, consider, enjoy, escape, finish, keep, mind, miss, suggest等動詞; can』t stand, give up, feel like, keep on, think of, set about, dream of 等短語。
2. 在下列短語中,to是介詞,後面應用動詞-ing形式作賓語:
be / get used to, look forward to, devote…to, pay attention to, object to等。
3. 下列動詞或短語既可以跟動詞-ing形式作賓語,也可以跟不定式作賓語,但意義上有區別:
● like, love, prefer如表示經常性的行為後接動詞-ing形式;如表示具體的行為常用動詞不定式,但要注意:如果like, love, prefer前有would,後面則接動詞不定式。如:Would you like to go shopping with me?
● 下列幾組詞接動詞-ing形式作賓語和不定式作賓語含義不同:
forget doing 忘記已做過某事; forget to do 忘記要做某事
remember doing 記得做過某事; remember to do 記住要做某事
mean doing 意思是,意味著; mean to do 打算做
regret doing 後悔做過某事; regret to do 遺憾要做某事
can』t help doing 禁不住做; can』t help (to) do 不能幫忙做。
● 在allow, permit, advise等動詞後直接跟動詞-ing形式作賓語,如果這些詞後面有名詞或代詞作賓語,其後要用動詞不定式作賓語補足語。如:
We don』t allow smoking in the classroom.
We don』t allow students to smoke.
● 動詞need, require, want作「需要」解時,其後用動詞-ing的主動形式或不定式的被動形式作賓語,這時動詞-ing的主動形式表被動意義。如:
Your coat wants washing. = Your coat wants to be washed.
三、動詞-ing的復合結構
動詞-ing的復合結構即:物主代詞或名詞所有格(作賓語時也可以用代詞賓格或名詞普通格) + 動詞-ing。如:
Lucy』s turning up surprised everyone present.
Would you mind my / me using your mobile phone?
四、動詞-ing的時態、語態以及否定形式動詞-ing有一般式(doing) 和完成式 (having done) 兩種時態,一般式的被動語態是being done,完成式的被動語態是having been done。動詞-ing的完成式所表示的動作發生在謂語動詞的動作之前。
動詞-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.

㈤ 外研社高中英語教材必修三,四單詞表
發的還是符合WEF各個地方 的看看啊的好多個飛飛
㈥ 外研社高一英語必修3知識點
一. 直接引語和間接引語
(一)直接引述別人的原話,叫做直接引語;用自己話轉述別人的話,叫做間接引語。間接引語一般構成賓語從句。直接引語必須放在引號內,間接引語則不用引號。直接引語改為間接引語時,除將引語部分變成賓語從句外,還必須對直接引語中的人稱、時態、指示代詞、時間狀語、地點狀語等進行改變。
1. 時態的變化:直接引語變為間接引語時,通常受轉述動詞said, asked等的影響而使用過去化的時態,即把原來的時態向過去推,也就是一般現在時變為一般過去時,現在進行時變為過去進行時,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. 人稱代詞、指示代詞、時間狀語、地點狀語等等的變化: 根據意義進行相應的變化,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)直接引語改為間接引語時,都使用陳述語序,但是因為原句的句式不同,所以變成間接引語時所用的連詞會有所不同。直接引語如果是一般疑問句,用連接詞whether或if;如果是特殊疑問句,則用疑問詞引導間接引語。轉述的動詞一般用asked,可以在其後加上一個間接賓語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.
直接引語如果是祈使句,改為間接引語時,要將祈使句的動詞原形變為帶to的不定式,並在不定式的前面根據原句的語氣(即請求或命令)加上ask, tell, order等動詞,如果祈使句為否定式,則在不定式前加not。其句型為: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. 各種時態的被動語態
被動語態概述
被動語態的概念:它是動詞的一種形式,表示主語與謂語之間的執行或被執行關系。主動語態表示主語是謂語動作的執行者,例如:They saw the little boy crying by the river. 被動語態表示主語是謂語動作的承受者,例如:The little boy was seen crying by the river.
被動語態的構成
被動語態的形式是由「助動詞be+動詞的過去分詞」構成。助動詞be隨著主語的人稱、數、時態等的不同而變化。幾種常見時態的被動語態形式如下:
1. 一般現在時 am/is/are + 過去分詞
例如:Rice is planted in the south of China.
2. 一般過去時 was/were + 過去分詞
例如:These trees were planted the year before last.
3. 一般將來時 will/shall + be + 過去分詞
例如:A sports meeting will be held next week in our school.
4. 現在進行時 am/is/are + being + 過去分詞
例如:Your radio is being repaired now.
5. 過去進行時 was/were + being + 過去分詞
When he got there, the problem was being discussed.
6. 現在完成時 have/has + been + 過去分詞
His work has been finished.
Has his work been finished? Yes, it has. / No, it hasn』t.
7. 過去完成時 had + been + 過去分詞
注意:
1.除了be之外的其它系動詞如get, stay等也可以和過去分詞構成被動語態。例如:Their questions haven』t got answered.
2. 含有情態動詞的謂語變成被動語態使用「情態動詞+ be + 過去分詞」結構。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」等結構的謂語,其被動語態分別用「be going to + be + 過去分詞」和「be to + be + 過去分詞」。例如:
The problem is going to be discussed at the next meeting.
All these books are to be taken to the library.
4. 被動語態與系表結構的區別:「連系動詞+用作表語的過去分詞」構成的系表結構,與被動語態的形式完全一樣,所以應注意它們的區別。被動語態中的過去分詞是動詞,多強調動作;系表結構中的過去分詞相當於形容詞,多強調狀態。前者通常可用by 引出動作的執行者,而後者則不可以。例如:
The map was changed by someone.(被動結構)
That custom remained unchanged for many centuries.(系表結構)
系表結構中的過去分詞通常可被very修飾,被動語態中的過去分詞往往要用much修飾。
例如:
He was very excited.(系表結構)
He was much excited by her words.(被動結構)
5. 主動形式表被動意義。有些動詞的主動形式有被動意味,如 open, read, sell, shut, wash, wear, write等。此時句子的主語一般是物。例如:
These books sell well. 這些書很暢銷。
The door won』t shut. 這門關不上。
The clothes wash well. 這些衣服很好洗。

高一英語外研版必修四第四單元cultural corner原文及翻譯:
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,火箭是我們用來將宇航員送入太空的非常先進的機器。它們也被用在慶祝重大事件的焰火表演中,像奧運會的閉幕式或2000年新千年的開始。
火箭很可能是在大約兩千年前被偶然發明出來的。中國人有一種裝在竹管里的火葯,這種火葯是節日中被用來扔進火里爆炸的。也許一些竹管從火堆里躥了出來,而不是在裡面炸開。中國人發現從竹管里釋放出來的氣體可以使其飛向空中。於是關於火箭的想法誕生了。
火箭第一次被用於軍事上是在1232年。那時宋朝正與蒙古作戰。在開封戰役中,宋軍射出了「飛火箭」。這些竹管被綁到一根長棍上,這根長棍可幫助火箭沿筆直的方向飛行。不久,蒙古人學會了怎樣自己製造火箭,並且可能是他們將其引入歐洲的。在13世紀到15世紀期間,在英國、法國和義大利有很多關於火箭的實驗。它們都用於軍事目的。一個義大利科學家甚至發明了一種可以飛過水面打中敵艦的火箭。
但並不是每個人都想將火箭用於戰爭。一個名叫萬戶的中國官員發明了一種「飛椅」。他把兩個大風箏綁到椅子上,又把47個火箭綁在風箏上。火箭被點燃了,發生了巨大的爆炸,出現了厚厚的濃煙。當煙霧消散時,萬戶和他的椅子已經不見了。沒有人知道發生了什麼。萬戶被炸死了?還是他被載入了數英里遠的太空而成為世界上第一個宇航員了呢?

亞洲的沙塵暴
幾百年以來,沙塵暴一直是許多亞洲國家面臨的主要災難.科學家嘗試過多種方法解決這個問題,在中國,也發動了群眾運動來對付沙塵暴.
沙塵暴是夾帶沙塵的強烈而乾燥的風.沙塵暴夾帶的沙塵含量常常很大,以致於可以遮天蔽日.風力強大時可以搬動沙丘.世界上沙塵暴發生的四個主要地區是中亞、北美、中非和澳大利亞.來自內蒙的任建波是這樣來描述他小時候遭遇的一次沙塵暴的:
「遇上沙塵暴是一種可怕的經歷,」他說,「你一點辦法也沒有.那是我遭遇過的最可怕、最危險的境況.你只能祈求會活下來.那時候我覺得我會消失在沙塵下.」
中國的西北地區是中亞沙塵暴中心的一部分.沙塵暴發端於沙漠地區.因「荒漠化」越發嚴重,中國近年來發生沙塵暴的次數明顯增加了.這是由於氣候變化和人們伐樹挖草,使土地變成荒漠後產生的一種作用.
沙塵暴有時候會影響北京.居民醒來時,看到昏黃的天空,狂風夾著黃沙在城裡肆虐.暴風有時持續一整天,車輛開得很慢,因為濃濃的塵埃降低了能見度.
中國中央氣象站能在沙塵暴到達北京前幾周預報沙塵暴,但沙塵暴的力量有時很驚人.沙塵暴到來時,氣象專家建議人們不要外出.家住北京的黃小梅說:「在沙塵暴中騎車真可怕.風力很強,呼吸困難,沙塵使人難受.所以不要出門,最好帶上口罩.」
沙漠離北京西境只有250公里.為阻止沙漠的逼近,政府已經開始植樹.政府已經種了300億棵樹,並准備在未來的五年裡繼續種植.
祝你開心如意!
