A. 2021年上半年英语四级语法用法解析
【 #四六级考试# 导语】中国有“书读百遍,其义自见”的古谚,一直在强调重复练习的重要性。2020年考试日益临近,多看书,勤做题是大有裨益的。 !【篇一】2021年上半年英语四级语法用法解析
英语四级语法用法辨析:first 与 at first的用法区别
(1) first 意为“先”“首先”,主要用来说明顺序,暗示接下去还有其他的动作或拿宽事件要发生,因此其后往往接有或暗示有 then, next, last 之类的词。如:
First think and then speak. 先想后说。
First, I must apologize to you. 首先,我要向你们表示歉意。
(2) at first 意为“起初”“开始”,它主要强调前后对照,暗示接下去的动作与前面的动词不同甚至相反,因此其后通常有but, afterwards, soon, at last 等词语相呼应。如:
The work was hard at first, but I got used to it. (www.yingyuyufa.com)起初这活儿很累,不过后来我习惯了。
At first they were very happy, but then things started going wrong. 起初他们生活得很幸福,但后来就开始出问题了。
注意上,at first与at last不是一对反义词组,后者的意思是“终于”“最终”。如:
She has at last got everything ready. 她最后把一切准备好了。
At last the bus came. I had been waiting for half an hour. 最后公共汽车来了,我已等了半小时。

英语四级语法用法辨析:write 与write about的区别
write 与write about的区别。问题见:
1. write your ideas 意思是:把你的想法(观点,看法)写出来。
2. write about your ideas 意思是:把你想法(观点,看法)的论据(理由)写出来。
前者郑敏磨表示:动宾关系是“直接”的;后者表示:动宾关系是“间接接”的。
有网友曾经问我类似的句子,也许能给你些许启发。
网友问我:I read about the book before. 请问老师,“读书”是read the book,为何还要加一个about呢?
这个问题很有意思。在这个句子中,read about the book不是“读书”,而是“读到关于那本书的介绍”。请比较以下两个句子有何异同:
I've read the novel and I think it is very instructive. 我读过那本小说,我认为它很有教育意义。
I've read about the novel, but I wonder whether it is worth reading at all. 我读过那本小说的介绍,但我不知道它是否值得一读。
read和read about为何有如此大的差别呢?原来,在read the novel中,read是及物动词,是一种直接的阅读;而在read about the novel中,read是不及物动词,是一种间接的阅读,可以理解为在它后面省略了something, 即:read something about the novel。总之,read the book和read about the book是直接和间接的关系。又如:
I know about him, but I don't know him. 我听说过他,但我不认识他。
We heard about / of the pop singer, but unfortunately we haven't heard her sing. 我们听说过这位流行歌手,但很遗憾我们没有亲耳听她演唱过。
I am not a writer, and I can't write a novel. But I can write about a novel. 我不是作家,我不会写小说。但我可以写小说评论。
【篇三】2021年上半年英语四级语法用法解析
英语四级语法用法辨析:China's与Chinese的区别
1. China's为名词所有格,强调所属关系。如:
China's population is large. 中国人口众多。
Hainan is China's second largest island. 海南是中国第二大岛。
The Yellow River is China's second longest river. 黄河是中国第二大河。
China's countryside looks its best in May and June. 中国的农村在五六月时景色最美。
2. Chinese为形容词,表示属性,视所修饰的名词不同,意思稍有不同:
Maotai is a Chinese wine. 茅台是一种中国酒。
Are you into Chinese food? 你对中国菜有兴趣吗?
This book is about Chinese traditkmal medicine. 这本书是讲中医的。
This was a record set by a Chinese girl. 这是一个中国姑娘创造的记录。
My strongest memory is when I attended a Chinese wedding. 我印象最深的是我参加的一次中国婚礼的情景。
Gone are the days when they could to what they liked to the Chinese people. 他们能够对中国人民为所欲为的日子一去不复返了。
Thinking that traditional Chinese medicine might help, they sent for an old Chinese doctor. 他们请了一位老中医,因为他们考虑到也许中医会有效。

谈谈alive的用法
1.关于比较等级的使用
表示“活着的”、“在世的”,其反义词是dead(死的);没有比较等级的变化。但表示“有活力的”、“活泼的”等义时,可以有比较等级的变化,且通常要加more,most 构成。如:
My grandfather is more alive than a lot of youngpeople. 我爷爷比许多年轻人还有生气。
2.关于用作定语
通差胡虚常不放在名词前作定语,但可作作表语或后置定语。如:
He must be still alive. 她一定还活着。
He‘s the happiest man alive. 他在世界上最幸福的人。
Although he is old, he is very much alive. 虽然他很老了,但还很有生气。
注意:
但是若本身带有修饰语,则可以用作前置定语:
a really alive student 一个十分活跃的学生
a really alive town 一个十分热闹市镇
除用作表语和有时用作定语外,alive有时还用作状语或补语。如:
He was buried alive. 他被活埋了。
The spy was caught alive. 特务被活捉了。
I‘m afraid he can't come back alive. 恐怕他不能活着回来。虚燃
3.关于修饰语的使用
一般不用very修饰,但可用 much,very much,all等修饰。如:
He is (very) much alive. 他非常活跃。
The city was all alive when we arrived. 我们到达时,城里非常热闹。
但是当 alive(to)表示“意识到”(=aware of)时,可用very修饰。如:
He is very alive to the danger. 他完全意识到了这危险。
4.用于搭配be alive with
该习语意为“充满”、“到处是”。如:
The woods are alive with birds. 树林中到处是鸟。
The street was alive with people. 街上挤满了人。
The sky was alive with stars. 满天星斗。
5.alive,living,live的区别
三者均可表示“活着”,但用法有区别:
做物(1)alive通常不放在名词前作定语 (可用作表语或后置定语),但是本身有修饰语时,可用作前置定语等 (见以上分析和例句);主要用于人或动物。
(2)living 可用作表语或定语,可用于人或物。如:
Both plants and animals are living things. 动植物都是生物。
My first English teacher is still living? 我的英语启蒙老师还健在。
English is a living language. 英语是一门活生生的语言。
从含义上看alive与living都可表示“活着”,含义很接近,只要句法适合,两者有时可互换。如:
the greatest scientist alive = the greatest living scientist 当代最伟大的科学家
Are your grandparents still alive [living]? 你祖父母还健在吗?
若要严格区分,两者仍有差别。如:
living 侧重指“健在”或“尚在人间”,而alive则侧重指生与死的“界限”:
In the car accident the mother was killed, but her two-year-old son was found alive. 在这次车祸中,母亲死了,但是她两岁的儿子却还活着。
(3)live 只用作定语 (前置),主要用于动物、植物等 (一般不用于人) .如:
He bought some live fish. 他买了几条活鱼。
Only a few live trees were left after the fire. 火灾之后只剩下几棵树还活着。
【篇二】2021年6月大学英语四级语法考点整理
angry的介词搭配特点:
1.表示“对某人生气”,一般用介词 with(有时也用 at)
The teacher got angry with [at] me. 老师对我生气了。
有的词书认为:用with表示心中感到生气,而用at则表示怒气流露于外表,但总的说来此时还是用with的场合较多。
2.表示“对某事生气”,一般用介词 at(about)
He was rather angry at what you said. 他对你说的话相当生气。
I was angry about missing the film. 没看上那部电影我很气恼。
He was angry at being kept waiting. 他因久等而生气。
有的词书认为:at 之后接某人之言行,about 之后接某事,但这种区别并不十分严格,两者常可换用。
3.表示生气的原因,一般用介词for
He was angry with me for not having done anything. 因为我什么也没做,他对我很生气。
注:be angry 之后除搭配介词外,还可接不定式或从句:
He‘ll be angry to find that nothing has been done. 他发现什么都没做,他会生气的。
He was angry that the door was locked. 门锁上了,他很生气。
【篇三】2021年6月大学英语四级语法考点整理
-ed形容词与-ing形容词的用法区别
1. 以后缀-ed结尾的形容词(如 ashamed,delighted,excited,frightened,interested,moved,pleased,surprised,worried 等)通常用于说明人,不用于说明事物,即使它们所修饰的名词是事物,那它们指的也是与该事物相关的人。如:
He had a pleased smile on his face. 他脸上露出了满意的微笑。
He told me the news in a very excited voice. 他告诉了我这个消息,声音很激动。
第一句中的a pleased smile 意为“满意的微笑”,它指的是某人因感到满意发出的微笑;第二句中的 excited voice 指的是“激动的声音”,即指的是带有这种声音的某人感到激动。
原则上,-ed 形容词通常直接用于说明人,若修饰事物,则多为 air(神态),appearance(外貌),cry(哭声),face(表情),voice(声音),mood(情绪)等与显示某人的情感状况的名词。
2. 以后缀-ing结尾的形容词(如 delighting,exciting,frightening,interesting,moving,surprising,worrying 等)主要用于说明事物,表示事物的性质或特征,若用它们说明人,则表示此人具有此性质或特征。如:
The story is very interesting. 这个故事很有趣。
The man is very interesting. 这个人很有趣。

2) 助动词协助主要动词完成以下功用,可以用来:
a. 表示时态,例如:
He is singing.他在唱歌。
He has got married.他已结婚。
b. 表示语态,例如:
He was sent to England.他被派往英国。

和more有关的词组

典型例题
1)The weather in China is different from____.
A. in America B. one in America C. America
D. that in America
答案:D. 本题意为"中国的天气比美国热。"比较的是天气而不是国家,C不能选。A没有名词,后句成分不全,排除。B和D中,B中的one常用来代替可数名词,而that可车以代替不可数或抽象名词,所以选D。
2)After the new technique was introced,the factory proced ___ tractors in 1988 as the year before.
A. as twice manyB. as many twiceC. twice as manyD. twice many as
答案C. 此句意为"这个厂1988能生产的拖拉机是往年的两倍"。 表示倍数用"倍数+ as + 形容词原形+ as +比较对象"的句型。所以此句答案为C。

【 #四六级考试# 导语】中国有“书读百遍,其义自见”的古谚,一直在郑敏磨强调重复练习的重要性。2021年考试日益临近,多看书,勤做题是大有裨益的。 考 网!【篇一】2021年6月英语四级语法用法辨析
1. 在系表结构后接不定式时,不能按汉语意思用“人”作主语,而用形式主语it。
如:
他有必要同我们一走去。
误: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.
在以上后接 that 从句的句型中,从句谓语通常要用虚拟语气。
又如:
It's necessary that he (should) buy a computer.
他有必要买台电脑。
It's necessary that we (should) ask for her advice.
我们有必要去征求一下她的意见。
2. 表示“对……有必要”,其后可接介词 to 或 for。
如:
Food is necessary for [to] life.
食物对生命是必要的。
Sleep is necessary to [for] one's health.
睡眠对健康是喊斗必不可少的。
当后接不拿宽定式的复合结构时,引导不定式逻辑主语的介词通常只用for而不用 to。
如:
It's necessary for us learn a foreign language.
我们有必要学习一门外语。
3. 可与 if, when, where, as, whenever, wherever, although等连词构成省略句(可以看成是其中省略了it is)。
如:
If necessary, ring me at home.
如果必要,可往我家里打电话。
Tell him all about it when necessary.
在必须的时候把一切都告诉他。
Where necessary, improvements will be made.
哪儿需要,就在哪儿改进。
They believed in the application of force wherever necessary.
凡属必要的地方他们都主张使用武力。
另外,注意习语as necessary(按需要,根据需要),than necessary(比需要的更)。
如:
We'll be adding more workers as necessary. 我们会按需要增加更多的工人。
I drove ten miles farther than necessary. 我开车开过了10英里。
【篇二】2021年6月英语四级语法用法辨析
1. 与 can, be able to 等连用,表示“担负得起”某事或某物的费用、损失、后果等,或表示“抽得出”时间等,后面通常可接名词、代词、不定式等(多用于否定句或疑问句)。如:
I can't afford (to buy) a new coat. 我没钱买件新外衣。
He can't afford the time for it. 他抽不出时间来做此事。
He says he really can't afford to wait another day. 他说他确实一天也不能再等了。
2. 表示“提供”“给予”,其后可以接双宾语(直接宾语通常为抽象概念),若双宾语交换位置,要用介词 to(此时无需连用 can, be able to等)。如:
他的来访给我们带来极大的快乐。
正:His visit affords us great pleasure.
正:His visit affords great pleasure to us.
【篇三】2021年6月英语四级语法用法辨析
owever与but 的用法区别
两者均可表示转折或对比,意为“但是”、“可是”、“然而”等,但有区别:
1. 表示转折时,but 是连词。如:
He is young but very experienced. 他虽年轻,但经验很丰富。
He has three daughters but no sons. 他有3 个女儿,但没有儿子。
He likes sports, but his wife likes music. 他喜欢运动,而他妻子则喜欢音乐。
2. however 表示“然而”、“可是”时,有的词书认为它是连词,有的词书认为它是副词。之所以将其视为副词,也许是因为像许多副词一样不仅能位于句首,而且能位于句中(注意前后使用逗号),甚至句末 (注意其前也用逗号)。如:
Later, however, he changed his mind. 可是他后来改变了主意。
He hasn't arrived. He may, however, come later. 他还没有到,不过他等会儿可能会来。
He said that it was so; he was mistaken, however. 他说情况如此,可是他错了。
注:以上各例中的 however 不能换成 but,但可用 but 来改写。如:
He said that it was so, but he was mistaken. 他说情况如此,可他错了。
3. 当连接两个句子时,其前通常应用分号,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,但我想我们还得出去。
注:上例中的 however 不能换成 but,但可用 but 来改写 (注意所用标点的变化)。如:
It's raining hard, but I think we should go out.
