【 #四六級考試# 導語】中國有「書讀百遍，其義自見」的古諺，一直在鄭敏磨強調重復練習的重要性。2021年考試日益臨近，多看書，勤做題是大有裨益的。 考 網！【篇一】2021年6月英語四級語法用法辨析
1. 在系表結構後接不定式時，不能按漢語意思用「人」作主語，而用形式主語it。
如：
他有必要同我們一走去。
誤：He's necessary to go with us.
正：It's necessary for him to go with us.
正：It's necessary that he (should) go with us.
在以上後接 that 從句的句型中，從句謂語通常要用虛擬語氣。
又如：
It's necessary that he (should) buy a computer.
他有必要買台電腦。
It's necessary that we (should) ask for her advice.
我們有必要去徵求一下她的意見。
2. 表示「對……有必要」，其後可接介詞 to 或 for。
如：
Food is necessary for [to] life.
食物對生命是必要的。
Sleep is necessary to [for] one's health.
睡眠對健康是喊斗必不可少的。
當後接不拿寬定式的復合結構時，引導不定式邏輯主語的介詞通常只用for而不用 to。
如：
It's necessary for us learn a foreign language.
我們有必要學習一門外語。
3. 可與 if, when, where, as, whenever, wherever, although等連詞構成省略句(可以看成是其中省略了it is)。
如：
If necessary, ring me at home.
如果必要，可往我家裡打電話。
Tell him all about it when necessary.
在必須的時候把一切都告訴他。
Where necessary, improvements will be made.
哪兒需要，就在哪兒改進。
They believed in the application of force wherever necessary.
凡屬必要的地方他們都主張使用武力。
另外，注意習語as necessary(按需要，根據需要)，than necessary(比需要的更)。
如：
We'll be adding more workers as necessary. 我們會按需要增加更多的工人。
I drove ten miles farther than necessary. 我開車開過了10英里。
【篇二】2021年6月英語四級語法用法辨析
1. 與 can, be able to 等連用，表示「擔負得起」某事或某物的費用、損失、後果等，或表示「抽得出」時間等，後面通常可接名詞、代詞、不定式等(多用於否定句或疑問句)。如：
I can't afford (to buy) a new coat. 我沒錢買件新外衣。
He can't afford the time for it. 他抽不出時間來做此事。
He says he really can't afford to wait another day. 他說他確實一天也不能再等了。
2. 表示「提供」「給予」，其後可以接雙賓語(直接賓語通常為抽象概念)，若雙賓語交換位置，要用介詞 to(此時無需連用 can, be able to等)。如：
他的來訪給我們帶來極大的快樂。
正：His visit affords us great pleasure.
正：His visit affords great pleasure to us.
【篇三】2021年6月英語四級語法用法辨析
owever與but 的用法區別
兩者均可表示轉折或對比，意為「但是」、「可是」、「然而」等，但有區別：
1. 表示轉折時，but 是連詞。如：
He is young but very experienced. 他雖年輕，但經驗很豐富。
He has three daughters but no sons. 他有3 個女兒，但沒有兒子。
He likes sports, but his wife likes music. 他喜歡運動，而他妻子則喜歡音樂。
2. however 表示「然而」、「可是」時，有的詞書認為它是連詞，有的詞書認為它是副詞。之所以將其視為副詞，也許是因為像許多副詞一樣不僅能位於句首，而且能位於句中(注意前後使用逗號)，甚至句末 (注意其前也用逗號)。如：
Later, however, he changed his mind. 可是他後來改變了主意。
He hasn't arrived. He may, however, come later. 他還沒有到，不過他等會兒可能會來。
He said that it was so; he was mistaken, however. 他說情況如此，可是他錯了。
註：以上各例中的 however 不能換成 but，但可用 but 來改寫。如：
He said that it was so, but he was mistaken. 他說情況如此，可他錯了。
3. 當連接兩個句子時，其前通常應用分號，或另起新句。如：
It's raining hard; however, I think we should go out. / It's raining hard. However, I think we should go out. 雨下得很大，但我想我們還得出去。
註：上例中的 however 不能換成 but，但可用 but 來改寫 (注意所用標點的變化)。如：
It's raining hard, but I think we should go out.

表示其他關系: (al)though, than, as/so…as, lest, in order that, so…that
Ⅵ 定語從句
限制和非限制性定語從句: 限制性定語從句是名詞片語不可缺少的一個組成部分, 去掉了會造成病句或意義不明確; 非限制性定語從句屬於補充說明性質, 去掉了不會影響主要意義, 通常用逗號與它的先行詞分開.
The boys who wanted to play football were disappointed when it rained.
The boys, who wanted to play football, were disappointed when it rained.
如果定語從句的先行詞是專有名詞, 或是帶有形容詞性物主代詞(my, his, etc)或形容詞性指示代詞(this, that, etc)作限定詞, 其後的定語從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 postgraates.
在非限制性定語從句中只能用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.
定語從句的引導詞
that, who, whom: 非限制性定語從句, 如果修飾人, 一般用who, 有時用that (作主語時用who較多). 如果關系代詞在從句中作賓語, 就應當用賓格 whom 或that, 但在大多數情況下都可以省略掉, 在口語中可用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.
但在介詞後只能用whom:
This is the man to whom I referred.
但在口語中一般都把介詞放到句子後面去, 這時可用that, 但省略時更多一些.
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.
限制性定語從句如果修飾「物」, 用關系代詞that的時候較多, 也有時用which.. 當這個代詞在從句中是用作賓語時, 在絕大多數情況下都是省略的, 特別是口語中(尤其是當被修飾的詞是all, everything等詞時):
Have you everything you need?
(Is there) anything I can do for you?
All you have to do is to press the button.

短語部分沒有獨立主語，則短語結構稱為非謂語動詞。
非謂語動詞的結構：分詞(分詞短語)
句子的主語決定非謂語動詞中的分詞是用主動還是被動形式。如果是句子的主語發出動作，則使用現在分詞;如果動作不是由句子的主語發出，則使用過去分詞。
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 將要被演奏; being performed 正在被演奏;

第一點：forget 忘記; [反義] remember 記得;
這兩個詞後加動詞不定式表示將要進行的行為;這兩個詞後加動詞ing形式表示已經做過的事情。
注意：動名詞與現在分詞形式一樣，但含義不同。這兩個詞後加動詞ing形式都是動名詞。
forget to do sth. 忘記要去做某事; forget doing sth. 忘記做過某事;
remember to do sth. 記得要去做某事; remember doing sth. 記得做過某事;
2. I remember _B_ to help us if we ever got into trouble.
A once offering B him once offering C him to offer D to offer him
offer vt. 提出，提供; offer sb. sth. / offer to do sth.
him once offering 如果改成 his once offering 也正確。
動名詞的復合結構：凡是一個動詞的後面可以加動名詞，就可以加動名詞的復合結構。
動作發出者 + 動名詞;當動作發出者名字給出時：名詞所有格 + 動名詞;當動名詞的復合結構在文章中出現，且動作發出者在前文中提過時：形容詞物主代詞(賓格)+ 動名詞。

非謂語動詞與獨立主格：短語，句子(或者句子，短語)
當短語部分有獨立主語，並且該主語不同於句子主語，這時短語結構稱為獨立主格。(它最明顯的特點是短語部分有獨立的主語)。
獨立主格的結構1：名詞(代詞)+ 分詞 [現在分詞、過去分詞]
現在分詞表示主動的，正在進行的行為;過去分詞表示被動的，已經完成的行為。 作題時要通過判斷動作與名詞(代詞)之間的關系來確定是使用現在分詞還是過去分詞。當動作由名詞(代詞)發出時使用現在分詞，而名詞(代詞)是受動者時則用過去分詞。
1. Silver is the best conctor 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; 四級中的考點就是現在分詞和過去分詞的區別。
獨立主格的結構2：with + 名詞(代詞)+ 分詞 [句子當中作狀語]
3. After the Arab states won independence， great emphasis was laid on expanding ecation， 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(相當於and); be encouraged不會考。
動詞不定式有預示將來行為的含義。to be encouraged 將要被鼓勵;
been encouraged 已經被鼓勵完了，與主句的謂語動詞相對;being encouraged 正在被鼓勵
短語部分沒有獨立主語，則短語結構稱為非謂語動詞。
非謂語動詞的結構：分詞(分詞短語)
句子的主語決定非謂語動詞中的分詞是用主動還是被動形式。如果是句子的主語發出動作，則使用現在分詞;如果動作不是由句子的主語發出，則使用過去分詞。
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 將要被演奏; being performed 正在被演奏;
一些特殊的動詞：
第一點：forget 忘記; [反義] remember 記得;
這兩個詞後加動詞不定式表示將要進行的行為;這兩個詞後加動詞ing形式表示已經做過的事情。
注意：動名詞與現在分詞形式一樣，但含義不同。這兩個詞後加動詞ing形式都是動名詞。
forget to do sth. 忘記要去做某事; forget doing sth. 忘記做過某事;
remember to do sth. 記得要去做某事; remember doing sth. 記得做過某事;
2. I remember _B_ to help us if we ever got into trouble.
A once offering B him once offering C him to offer D to offer him
offer vt. 提出，提供; offer sb. sth. / offer to do sth.
him once offering 如果改成 his once offering 也正確。

英語四級語法用法辨析：until 後接過去分詞
請看這道題，這個until 後要接過去分詞嗎?
He is a man of few words, and seldom speaks until _________ to.
A. spoken B. speaking C. speak D. be spoken
【分析】此題容易誤B，認為until 是介詞，後接動詞時用動名詞形式。其實，此題應選A，until spoken to 為 until he is spoken to 之省略。句意為「他是個沉默寡言的人，別人不同他說話，他很少同別人說話」。按英語習慣，一些表示時間、地點、條件、方式、 讓步慧春等的狀語從句，若其主語與主句主語一致，且從句謂語包含動詞be, 那麼可將從句的主語和動詞be省略：
You must study hard while (you are) young, or you will regret when (you are) old. 趁年輕時要努力學習，不然到老了你會後悔的。
I won't go unless (I am) invited. 我不會去, 除非請我。
Look out for cars when (you are) crossing the streets. 過馬路時要注意汽車。
While (I was) waiting I was reading some old magazines. 等的時候我在看一些舊雜志。
He worked very hard though (he was) still rather poor in health. 盡管身體還不好，但他仍努力工作。
He will work hard wherever (he is) sent by the Party. 無論黨把他派往哪裡,他都會努力工作。
請再看兩道試題：
(1) If carefully _________, the experiment will be successful.
A. do B. does C. done D. doing
答案選C，可視為 if it is carefully done 之省略。
(2) The research is so designed that once _________ nothing can be done to change it.
A. begins B. having begun C. beginning D. begun
答案選D，可視為 once it is begun 之省略。
【篇三】2020年12月英語四級語法用法講解
英語四級語法用法辨析：介詞below與under的用法區別
1. 兩者都可表示「低於」，under 主要表示垂直在下的正下方，而 below 則不一定表示正下方(即可以是正下方或非正下方)。如：
Look in the cupboard below [under] the sink. 到洗碗池下面的櫃子里找一找。
The climbers stopped 300 meters below the top of the mountain. 登山隊員們在離山頂 300 米處停了下來。
換句話說，表示正下方，兩者都可用;不表示正下方，則通常用below。
2. 兩者均可表示數量方面的「少於」，但在現代英語中，以用 under 為多見。如：
He can't be much below [under] sixty. 他的年齡不可能比 60 歲小很多。
There were under forty people at the meeting. 參加會議的人不足 40 人。
It took us under an hour. 我們用了不到 1 個小時。
註：在現代英語中，below 表示「少於」，主要用於表示溫度、高度以及有縱向標准可比的情況。如：
This place is below sea level. 此地在海平面以下。
The temperature is two degrees below zero. 溫度是零下 2 度。
3. 若表示一物被另一物所覆蓋，則通常用 under。如：
She crept in beside him under the bedclothes. 她鑽進被窩躺在他身旁。
4. 表示職位、級別等關系時，用 under 表直接關系，用 below 表非直接關系。比較：
Mr A is under Mr B. A 先生是 B 先生的部下。
Mr A is below Mr B. A 先生比 B 先生職位低。
