㈠ 一些英語語法問題。
加定冠詞the，在這個句型中is後面不能接名詞，要加定冠詞the表示銜接
㈡ 一些英語語法問題 （要解釋）
第一第二個問題其實是同樣的，在語法中，you是第二人稱，且單復數形式一致，第二人稱用的永遠都是are，與單復數無關
後面的問題總結下來是一類的，解釋其實很簡單，第一第二人稱用do，第三人稱單數形式用does，樓主弄反了。其實所有的動詞，比如go, make, get的第三人稱單數形式都是類似的：goes, makes, gets，並非樓主所理解的名詞+s是復數動詞+s就也是復數，動詞+s表示主語是單數
第一人稱即I,We，第二人稱即you，第三人稱即he,she,it。其中it可代表任何其它物品，比如this computer。也就是說，在主語是he, she, it（泛指所有的東西）的時候，動詞用單數
關於Where is your book? On the desk.這句話，這是完全正確的，不知樓主的疑問是什麼？
希望有幫助:)
建議樓主去買一本語法書來看，也許更有幫助，也講的更系統
㈢ 關於一些英語作文語法問題
既然是計劃
除了將來時還有其他的時態合適嗎？時間點只是表示某件事情的時間
也是將來要發生的啊
所以是一般將來時
㈣ 一些英語語法問題
we are brothers ,are not we?是正確的。有系動詞的則直接用系動詞反問。這應該稱為反義疑問句吧。
從網上可以找到的——反意疑問句的規律 ：
1) 陳述部分的主語是I，疑問部分要用 aren't I.
I'm as tall as your sister，aren't I?
2) 陳述部分的謂語是wish，疑問部分要用may +主語。
I wish to have a word with you, may I?
3) 陳述部分用 no, nothing, nobody, never, few, seldom, hardly, rarely, little等否定含義的詞時，疑問部分用肯定含義。
The Swede made no answer, did he / she?
Some plants never blown (開花), do they ?
4) 含有ought to 的反意疑問句，陳述部分是肯定的，疑問部分用shouldn't / oughtn't +主語。
He ought to know what to do, oughtn't he? / shouldn't he?
5) 陳述部分有have to +v. (had to + v.)，疑問部分常用don't +主語（didn't +主語）。
We have to get there at eight tomorrow, don't we?
6) 陳述部分的謂語是used to 時，疑問部分用didn't +主語或 usedn't +主語。
He used to take pictures there, didn't he? / usedn't he?
7) 陳述部分有had better + v. 疑問句部分用hadn't you?
You'd better read it by yourself, hadn't you?
8) 陳述部分有You'd like to +v. 疑問部分用wouldn't +主語。
You'd like to go with me, wouldn't you?
9)陳述部分有must 的疑問句，疑問部分根據實際情況而定。
He must be a doctor, isn't he?
You must have studied English for three years, haven't you? / didn't you?
He must have finished it yesterday, didn't he?
10) 陳述部分主語是指示代詞或不定代詞everything, that, nothing, this, 疑問部分主語用it。
Everything is ready, isn't it?
11) 陳述部分為主語從句或並列復合句，疑問部分有三種情況：
a. 並列復合句疑問部分，謂語動詞根據鄰近從句的謂語而定。
Mr. Smith had been to Beijing for several times, he should have been in China now, shouldn't he?
b. 帶有定語從句，賓語從句的主從復合句，疑問部分謂語根據主句的謂語而定：
He is not the man who gave us a talk, is he?
He said he wanted to visit Japan, didn't he?
c. 上述部分主句謂語是think, believe, expect, suppose, imagine等引導的定語從句，疑問部分與賓語從句相對應構成反意疑問句。
I don't think he is bright, is he?
We believe she can do it better, can't she?
12) 陳述部分主語是不定代詞everybody, anyone, somebody, nobody, no one等，疑問部分常用復數they，有時也用單數he。
Everyone knows the answer, don't they? (does he?)
Nobody knows about it, do they? (does he?)
13) 帶情態動詞dare或need的反意疑問句，疑問部分常用 need (dare ) +主語。
We need not do it again, need we ?
He dare not say so, dare you?
當dare, need 為實義動詞時，疑問部分用助動詞do + 主語。
She doesn't dare to go home alone, does she?
14) 省去主語的祈使句的反意疑問句，疑問部分用will you。
Don't do that again, will you?
Go with me, will you / won't you ?
注意： Let's 開頭的祈使句，後用shall we?
Let us 開頭的祈使句，後用will you?
Let's go and listen to the music, shall we?
Let us wait for you in the reading-room, will you ?
15) 陳述部分是"there be"結構的，疑問部分用there省略主語代詞。
There is something wrong with your watch, isn't there?
There will not be any trouble, will there?
16) 否定前綴不能視為否定詞，其反意疑問句仍用否定形式。
It is impossible, isn't it?
He is not unkind to his classmates, is he?
17) must在表"推測"時，根據其推測的情況來確定反意疑問句。
He must be there now, isn't he?
It must be going to rain tomorrow, won't it?
另一個問題——
we have already known that.才是正確的哦，因為完成時的基本形式是have+動詞的現在分詞形式，know的過去式是knew，完成時是known，再比如do-did-done。我們已經完成了則是we have already done it.
㈤ 關於英語一些語法問題
語法系列復習專題九-----名詞從句、定語從句
名詞從句
名詞從句有四類：賓語從句、主語從句、表語從句、同位語從句。例如：
賓語從句：I don』t know where he will go.
主語從句：Where he will go is unknown.
表語從句：The problem is how we can get so much money.
同位語從句：We all feel sorry about the news that he failed in the game.
下面幾點是學習名詞從句要加以注意的：
1． whether和if都可以引導賓語從句表達「是否」意，（即引導賓語從句時if和whether
可以互換）但以下幾種名詞從句要用whether（不用if）引導：
（1） 引導主語從句，且在句首時。例：Whether he has won the tennis is not known.(但
It is not known whether/if he has won the tennis).
（2） 引導表語從句時。例The problem is whether he can get a job.
（3） 引導同位語從句時。例：I have no idea whether he will come.
（4） 介詞後的whether從句。例：I worry about whether I hurt her feelings.
2． 位於句首引導主語從句的that不可忘。
例如：That he got the first place in the competition surprised all of us.
3． 在「It is suggested/proposed/ordered/a pity/no wonder/necessary/strange/…＋
that從句」結構中，that從句謂語有時用（should）do這樣的虛擬語氣形式。
例如：It is suggested that we(should) improve the relations between us.
It is a pity that one(should) stay in one place all one´s life.
It is strange that she should have failed to see her own shortcomings（缺點）.
4． 在「The reason why…is that…」句式中that不要誤為because.
例如：The reason why he didn´t go to school yesterday is that he was ill.
5． 名詞從句中that,what用法比較：
引導名詞從句的that是連詞，在句中無成份，無意義，而what是連接代詞，what＝the
thing(s) that.
例如：It was told in yesterday´s newspaper that what the students had done was praised
by the factory.
I know that he will study.
I know what he will study.
That he works hard at his lessons is known to us all.
What he works hard at is known to us all.
All I ask is that you should tell the truth./He is not what(＝the person that)he
used to be.他和以前大不相同了。
6． where在名詞從句中的使用特點：
where在名詞從句中有時可以變為「the place where」,有時可以變為「介詞＋the place where」 形式。例如：
主從：Where(＝The place where)she has gone is still unknown.
賓從：Would you please tell me where(＝the place where) Mr Smith lives?
表從：Your dictionary remains where(＝in/at the place where)you put.
同位從：Have you any idea where(＝of the place where) she is spending her holidays?
7． 無論是哪種名詞從句都是陳述語序。例如：
I know where he lives./Please tell me what her name is.
當一個特殊疑問句本身就是陳述語序（即「主＋謂＋（賓）」或「主＋系＋表」結構），將其變為間接引語（即賓語從句）時，無需改變語序。例如：
What´s the matter with him? She asked me what was the matter with him.
Who looks after your grandfather? He asked me who looked after my grandfather.
名詞從句考點分析
1．They want to know ______ do to help us. (NMET)
A. what they can B. how they can C. how can they D. what can they
析：此題要選陳述語序項，故應排除C、D。又因how they can do不完整，do後無賓
語，故也應排除，只有A項既是陳述語序，且what they can do完整正確地表達出「他
們能做些什麼」這一意思，故答案為A。
2．His teacher ______ he ______ bright and ______ he was worth teaching.
A.didn』t think;was;that B.thought;was;whether
C.didn』t think;was;× D.thought;wasn´t;×
析：觀察題目，可知think後跟有and連接的兩個並列賓語從句，這時前一個賓語從句
的引導語that可以省略，但引導後一賓語從句的that不可省略，據此，可排除C、D
兩個選項。若選B項，全句意思不通，而選擇A項可表達「他的老師認為他不聰明，不
值得教」這一意思，且語法結構無誤，故可定A是正確答案。
3．______ is done cannot be undone.
A.How B.That C.What D.Where
析：do一般作及物動詞使用，從題干看，需選一詞作主語（邏輯上是done的賓語）。
而A.How,D.Where均是副詞，不能作主語，故應排除。B項that一詞只能在定語從句
中作主語，不能在主語從句中作主語，也應排除。只有選what(＝the thing that),才
能正確表述「凡是做的不可不做」這一意思。
4．Take care ______ you don´t make mistakes in the coming exam.
A.of that B.about that C.for what D.that
析：take care是「注意」、「當心」意，後面可跟that引導的賓語從句來表達「當心
不要…」意思，據此，該題應選D。
5．To his surprise,the umbrella was not ______ he had put.
A.which B.where C.the place D.that
析：觀察題干，was not後是表語，根據where在表語從句中相當於in/at the place where,
將其置於空白處則可表達「傘不在他當初放的地方」這一意思，而C選項缺少詞，不可
選。A、D項皆不合用。
6．______ we can´t get seems better than ______ we have.
A.what;what B.what;that C.that;that D.that;what
析：此題顯然是要表達「我們得不到的東西似乎比我們得到的東西好。」這一意思，即
「A seems better that B」結構，根據what＝the thing(s) that這一特點，將其置
於兩空白處正好可以表達出前者比後者好這一意思，故答案為A。
7．______ we』ll go camping tomorrow depends on the weather.
A.If B.Whether C.That D.Where
析：此題depends前的主語從句是一個不肯定的內容，在句首表「是否」意時，只能用
Whether,不可用If。故答案為B。
8．______ they are most interested in is ______ they can proce more and better
cars.
A.That;how B.What;how C.What;what D.That;that
析：is前面是一個主語從句，要表達「他們最感興趣的（東西）」這一意思，只能選what
填入空白;is是表語從句，顯然只有選how才能表達「如何生產更多更好的汽車」，故
答案為B。
9．He made a suggestion that the English test ______ until next Wednesday.
A.will be put off B.be put off C.will put off D.put off
析：suggestion,order,adivce等詞後的同位語從句謂語要用（should）do的形式，且
該句中test與put off為被動關系，故選B。
10．I don´t think ______ he said something like that is right.
A.that B.what C.whether D.when
析：此句think後是一賓語從句，這個賓語從句的主語在is之前，它是一個被動句。
因為he said something like that已經含有主、謂、賓、狀等成分，只有選不表意義，
不做成分的that才合適，故選A。
定語從句
一、 定語從句與引導詞
定語從句是在復合句中修飾某一名詞或代詞的從句。被修飾的名詞或代詞叫做選行詞，
而引導定語從句的詞叫引導詞，有關系代詞和關系副詞兩類。
懂得什麼樣的先行詞後用什麼樣的引導詞是學好定語從句的關鍵。
1． 關系代詞有：that,which,who,whom,whose,在定語從句中作主語、賓語中表語，whose
作定語。代人的有：who,whom,whose,that；代物的有：that,which,whose.例如：
The man who helped you is Mr White.(who代人，在定語從句中作主語)
That is the person(whom/who/that) you want to see.(whom,who,that代人，在定
語從句中作賓語，可省略)
I´m not the fool(that) you thought me to be.(that代人，在定從中作表語)
A dictionary is a useful book which(＝that) tells us the meaning of words(which
或that代物，在定從中作主語)
2． 關系副詞有：when(指時間)，where(指地點),why(指原因)，在定語從句中作狀語。
例如：Would you suggest a time(when) we can have a talk?(when可省略)
The house where they live is not very large./This is the reason why he did not came to the meeting.
注意：不是表時間的先行詞都用when引導定從，不是表地點的先行詞都用where引導定從。例如：We´ll visit the factory which(＝that) makes radios.
(which或that在定從中作主語，where不可用主語，故不可用)
They still remember the happy days(which/that) they spent in Beidaihe.
(which或that在定從中作spent的賓語，when不可作賓語，故不可用)
二、限制性定語從句與非限制性定語從句
限制性定語從句和主句之間不用逗號分開，修飾主句中的某一個名詞或名詞片語或代
詞；非限制性定語從句常用逗號和主句隔開，可以修飾主句中的某一個詞，也可修飾整個句子。非限制性定語從句不能用that引導，引導非限制性定語從句的關系詞不能省略。非限制性定語從句例：Li Ping´s father, who works in a factory, is an engineer./He tore up my photo, which made me very angry.(which指代主句內容，因前後兩句是因果關系，此時which不可換為as。)
He is good at physics, as is known to us all.＝As is known to us all, he is good at physics.(as指代主句內容，在as is known/believed, as we all know/believe這類結構中as不可換為which)
三、 只用that引導和不用that引導的場合
1． 只用that引導和不用that引導的場合
1） 當先行詞既包括人又包括物時：He talked about the men and the books that attracted
him.
2） 指物的先行詞被any, every, only, very, all, no等修飾時：These are the very points that interest me./That´s the only watch that I like most.
3） 指物的先行詞被序數詞或形容詞最高級修飾時：The first step that we are to take is very difficult./This is the second card that he gave me.
4） 先行詞是指物的不定代詞all,little,few,much,及everything,anything,nothing等時：There is still much that can be done about it./Have you got everything that you need?
5） 先行詞是who時：Who that have seen him does not like him?
2． 不用that的場合如下：
1）非限制性定語從句中 Last night ,I saw a very good film,which was about the Long
March .
2）介詞放在關系代詞之前時 This is the man from whom I learnt the news
3）句中出現了that，或先行詞是that時 I have found that which I was looking for.
四、「介詞＋關系代詞」用法
1． 介詞的確定應依據定語從句中短語的習慣性搭配，例如：Who is the girl with whom you just shook hands?(shake hands with…是習慣性搭配)
2． 介詞常受先行詞的制約（即介詞和先行詞的搭配），例如：He built a telescope through which he could study the skies.(through which 即through the telescope)
3． 當關系代詞作「動詞＋介詞」固定短語的賓語時，此時因定短語中的介詞不能拆開移到關系代詞前。例如：This is the watch which you´re looking for./He is a kind of man whom you can safely depend on.
五、幾個名詞後的引導詞
1. situation後常用where,in which引導定語從句：Can you imagine a situation where/in
which you can use the word?
2. way(方式，方法)後常用in which或that或how引導定語從句，也可省略：Do you know the way(in which/that/how) he worked out the problem?
3. 「the same＋名詞」，「such＋名詞」，「as＋名詞」後通常用as引導定語從句。
例如：I have the same dictionary as you(have)./Such a book as you bought is not worth buying.
定語從句考點分析
1． The best work ______ Luxun wrote and ______ I have read has been made into a film.
A.which;that B.that;× C.×;that D.×;×
析：如果兩個定語從句並列，關系代詞作賓語時前一句的可以省略，但後一句的不可省略，故應選C。
2． It was in 1969 ______ two Americans got to the moon by space ship.
It was 1969 ______ two Amerians got to the moon by space ship.
A.when B.which C.that D.×
析：第一句是強調時間in 1969,強調結構是「It was＋強調部分＋that句」，故應選C。第二句It是表時間的，先行詞1969在從句中作狀語，故選A。
3． Is this the house ______ Shakespeare was born?
A.at which B.which C.in which D.at where
析：觀察題目，空白處只有填in which或where才能表達「這是莎士比亞出生的房子嗎？」這一意思，故答案為C。
4． Is this house ______ Shakespeare was born?
A.where B.which C.in which D.at which
析：將此句變為陳述句；This house is ______ Shakespeare was born.顯然is後是一表語從句，只有選where(＝the place where)才能表達「這是莎士比亞的出生地」這一意思，故答案為A。
5． In the dark street,there wasn』t a single person ______ she could turn for
help.
A.to whom B.of whom C.from whom D.that
析：「介詞＋關系代詞」要考慮短語搭配或與先行搭配，這道題短語turn to有關，故
應選A。
6． The two things ______ they felt very proud were Jim´s gold watch and Della´s
hair.
A．about which B.of which C.in which D.for which
析：涉及be/feel proud of短語，故答案為B。
7． Have you ever asked him the reason ______ may explain his being late.
A.why B.that C.for which D.what
析：此題易誤選A、C，因為先行詞是the reason,但細觀察分析，定語從句缺少主語，所以答案是B。注意what不能引導定語從句。
8． Farming is difficult ______ there is no rain.
A.where B.in place C.that D.the place where
析：因為difficult是形容詞，故其後不是定語從句。這兒的空白處應填引導狀語從句where(＝in the place where),全句表達「在沒有雨水的地方耕種困難」。這一意思，可見答案為A。
9． We need the same machine ______ in your factory.
A.which is being used B.as is being used
C.that is being used D.as it is being used
析：根據「the same＋先行詞」後跟as引導定語從句的原則，可知答案為B。
10．______ the people,not things ______ are most important.
A.There are;who B.Those are;that C.It is;that D.It was;who
析：仔細觀察分析題目，可知只有C構成強調句才有成立。當我們要檢驗視其為強調
句的判斷是否正確時，只要將「It is (或was)…that」這三個詞去掉，剩下部分讀
起來正確無誤，則證明判斷是正確的，反之是錯誤的。此題如不填「It is…that」
三詞，句子是The people,not things are most important.語義完整正確，說明選
C是對的。

very 強調這就是那本爸爸正在找的字典
㈦ 一些英語的語法問題
一實義動詞就是表示有實際意義的動詞，如eat（吃），walk（走路），smile(笑)等等。 非實內義動詞包容括系動詞，助動詞和情態動詞,非實義動詞，就是沒有實際意義的動詞。比如助動詞be, do 等。 be 單獨使用，構成各種進行時態，例如： I am working. 本句的am 是助動詞，與後面的現在分詞構成現在進行時態，它本身是沒有實際意義的，就是充當構成時態的助動詞，所以我們這時候把它叫做非實義動詞。 比如說助動詞do ，例如： Do sit down. 這里的do 是助動詞，起強調作用，沒有什麼實際的意思，所以是非實義動詞。 但是在句子中：do the homework 做作業,這里的do 是「做」的意思，有實際意義，所以這句中的do是實義動詞。
有動作對象的動詞。比如：go(home),thank(you).
沒有動作對象的動詞如：sleep.

㈨ 英語一些語法問題
1 (each procing 20 units)現在分詞做後置定語修飾hydro power，是短語，與時態無關
而後面(which proced only 10 units)是定語從句，表示過去生產的，修飾oil,這里的proced對應前面的was proced，都是過去式
procing almost 75% of electricty是現在分詞做伴隨壯語，同樣也與時態無關，這里的proced和前面的had developed 是對應的 都是過去式，不過前面一個用過去完成表完成，後面一般過去式只是表過去的狀態
2by （the time） 可以表示
1)到…為止
2)當……時
by the time 表示到…為止時，從句用過去時時，主句通常用過去完成時。
表示當……時，只是說過去某個時候的狀態，不表示完成，就用過去時。
By 2000 these two countries relied on different principal fuel sources.這里rely依靠沒有已經完成的意思，只是描述當時這個時間點的狀態。所以用過去時
其實By 2000 nuclear power had developed into the main source,procing almost 75% of electricty,while coal and oil together proced only 50 units.這句話就可以當作最好的例句了，前面表過去完成，後面表過去狀態
祝你開心 滿意記得採納哦~
㈩ 一些關於英語語法問題
He is pleased with what
He is satisfred that
第一個實際上是be+ adj +prep+從句
但第二個形容詞後接that 賓語從句,如何來分辨用法？第二種情況英語中有多少形容詞能這樣用呢？
第一句是介詞後跟的賓語從句，第二句和句子結構有關，主語+BE 形容詞+從句（賓語從句），這時我們把「BE 形容詞」看成是謂語動詞。如：I am sure that ....

It will do you no narm 對你沒有害處。這里 will是情態動詞么？情態動詞在表決心時一般不是主語為人么？也可為物么？
will表示決心時用於第一人稱，其他人稱可以表示將來。主語可以是物。
1.哪些動詞不能接用於do sth/sb to do 這種形式，直接加不定式做賓語
afford, agree, aim, appear, arrange, ask, believe, care, claim, decide, demand, desire, determine, expect, fial, hope, intend, learn, long, manage, mean, offer, pretend, promise, refuse, wish.這些詞後直接跟不定式，不過有些也可用於你說的那個結構。
2.哪些形容詞做表語主語不為人的。
這題不好歸納，總的來說，修飾物的形容詞自然就不用人來作主語，有一種形容符合，就是由動詞加ING構成的形容詞。如：interesting, moving, surprising.等。
