大家好,今天我将为大家讲解reduce的用法的问题。为了让大家更好地理解这个问题,我将相关资料进行了整理,现在就让我们一起来看看吧。
reduced和reduce
分词(包括过去分词和现在分词)可以做形容词,没什么奇怪。 起形容词作用的分词(形容词型分词)
a. 分词作定语的用法
1)总的特点
分词可以作定语,修饰或是限制一个名词,可以放在它前面,也可以放在它后面。一般说来,简单分词可以放在名词前面,分词短语放在名词后面。
a)放在名词前面的分词
1/表示动作的分词:
一个现在分词或过去分词放在名词前时,可以表示一时的动作,这时它的动词特点胜过形容词特点,相当于一个定语从句
Do you see the rising sun(=sun which is rising) in the east?
They tried to surround the retreating troops (=troops which were retreating).
The roaring lion frightened all the animals in the jungle.
They tried to deliver the besieged city (=city which was being besieged).
These repeated efforts(=efforts which were being repeated) were still inadequate.
Those oppressed nations (=nations that are being oppressed ) are rising to liberate themselves.
2/表示特点的分词:
它也可以表示比较长久或永久性的特点。这时它的形容词特点胜过它的动词特点:
Germs are living creatures (=not inanimate things, creatures that can live).
She is a charming lady (attractive lady, lady who charms others)
The working classes are usually poor.
There were many flying fish.
We watched the moving pictures (=motion pictures)
Used cars (=old cars,cars which have been used) are cheaper than new ones/
Stolen love (=Secret love, love which is stolen), though dangerous, tastes exceptionally sweet.
This printed matter may be sent by mail.
3/和用作形容词的动名词的差别:
用在名词前的现在分词和用在名词前起形容词作用的动名词是有区别的,从意思上、重音上及是否加连字号,都有区别。下面各对句子中,第一句中带-ing词尾的动词为分词,第二句中带-ing词尾的动词为动名词:
Boiling water(=Water that is boiling) can produce enormous power.
Water begins to boil at the boiling-point(=point at which liquid boils;而不是point which boils).
He is a walking dictionary (=dictionary that canwalk, learned man).
He came with a walking-stick (=stick for walking;非stick that os walking)
How clever that dancing bear (=bear that is dancing) is!
He is a dancing-master (=master who teaches dancing).
someone said many years ago that China was a sleeping lion (=lion that was sleeping).
He is in the sleeping-car (=car for sleeping,而不是 car that is sleeping).
Running water is cleaner than stagnant water.
It is a running-track for sportsmen.
4/用作名词的情况
和形容词一样,某些分词在加the时(后面不跟名词),可以代表一类人或一种抽象东西:
Which are more numerous, the dead or the living (=the living people)
Something must be done immediately with the wounded and the dying.
What should we do with the oppressed, the defeated the insulted and the injured?
Can we say anything about the unseen (=the thing unseen) and the unknown (=the thing unknown)?
放在名词后的分词
放在名词后的分词多数是分词短语,它可以变成一个定语从句(尽管定语从句不一定都能变成分词短语):
1/表示一时动作的分词短语:
The danger threatening the world (=which is threatening the area ) is too many people with too little food.
They looked on at the city being attacked by the enemy (=which was being attacked by the enemy).
The man being followed by guards (=who are being followed by guards) is a party leader.
2/表示长久特点的分词短语:
A man respecting others (=who respects others ) will be respected.
Can you teach a boy refusing to be taught (=who refuses to be taught)?
It is difficult to save a man enchanted by the beauty of a woman.
Books called the comics (=that are called the comics ) are sometimes harmful to children.
Any books well read (=that are well read ) are good books and any men well treated are good men.
decrease和reduce有什么区别?
decrease和reduce的区别为:指代不同、用法不同、侧重点不同
一、指代不同
1、decrease:减小,降低。
2、reduce:减少,缩小。
二、用法不同
1、decrease:decrease指各种事物逐渐减少、逐渐衰弱的过程,指逐渐地、不断地减少。
2、reduce:reduce的基本意思是“减少”,指重量、程度、数目、范围、速度等减少或降低,不仅可以指量的变化,还可以指质的转变。引申可作“降职”“使…陷入某种状态或状况中”“将…概括或简化”“将…还原”“征服”“攻陷”等解。
三、侧重点不同
1、decrease:是一种主观的减少。
2、reduce:是一种客观的减少。
减少的英文短语有哪些?
减少的英文短语有reduce to、decrease to。
1、reduce to英[r?dju?stu]美[r?du?stu]
[词典]使降低到;遭受;
[例句]The company must?reduce?costs?to?compete?effectively。
公司要有效地参与竞争必须降低成本。
2、decrease to英[d?kri?stu]美[d?kri?stu]
[词典] 减少到;
[例句]Feed velocity must?decrease?to?a maximum safe value before crossing the sharp?point。
在尖角过渡前,进给速度必须降到最大安全速度。
reduce用法介绍
1、reduce可用作及物动词,也可用作不及物动词。用作及物动词时接名词或代词作宾语。可用于被动结构。
2、reduce偶尔也可接动词不定式作宾语补足语,意思是“使…不得不…”。
3、reduce后常接介词by表示“以某幅度减少”或“以…方法减少”;reduce常接介词to表示“减少到…”或“使陷入…状态”。
这两句英语中reduce为什么接介词? reduce by 和 reduce to有什么区别?
The price was reduced by 30 percent.价格降低了30%。
The loss of metal has been reduced to less than 20 percent.金属的损失率已降到20%以下。
reduce有及物用法,为什么他们都须解接介词呢?
接介词的意思不一样。没有介词,后面就没有宾语了。
The price was reduced.价格降低了。
The loss of metal has been reduced.金属的损耗减少了。
reduce... by...减少了……(表示减了多少)(by表示程度)
reduce... to...减少到……(表示减到多少)(to表示结果)
例:
No-tillage without residue cover can reduce the erosion by 21.6%.?
另外,仅有免耕而没有秸秆覆盖能减少21.6%的沙尘量。
When that starts to happen we will reduce the price to 1.15 .?
一有种迹象发生,我们就会把价格降到1.15英镑。
decrease和reduce的区别是什么?
这两个词的区别我懂,decrease通常在句中既可以作名词,也可以作动词;而reduce通常在句中作动词,修饰主语或宾语。给大家总结了两个词的含义,先大概的了解一下~~
接下来让我们看下decrease和reduce的其他区别:
1. “Decrease”与“Reduce”在一些方面相似,都可以表示数量、大小、程度的降低,但“Decrease”更加正式、学术化,而“Reduce”则更加通用。
- The temperature decreased rapidly during the night.?
夜间温度急剧下降。

3. “Decrease”通常描述的是某种趋势或状态下降的过程,而“Reduce”则更多的描述某种行动或决策的结果。
- The decrease in the number of visitors to the museum is becoming a major concern.
博物馆游客数量的下降正日益成为一个主要问题。
- The government is taking steps to reduce pollution in the city.?
政府正在采取措施减少城市污染。
4. “Decrease”通常是指相对较小的下降或降低,而“Reduce”则可以指相对较大或显著的降低或削减。
- The price of gas decreased by a few cents over the weekend.?
周末天然气价格下降了几分钱。
- The company reduced its workforce by 20%, resulting in massive layoffs.?
公司裁员20%,导致大规模裁员。
5. “Decrease”在某些情况下可能是自然过程的结果,而“Reduce”通常需要外部介入才能实现。

鹿的数量由于缺乏食物而自然下降。
- The school reduced the size of its classes by hiring more teachers.?

- The number of cars on the road has decreased due to higher gas prices.?
由于汽油价格上涨,路上的汽车数量已经减少。
- The company has implemented measures to reduce waste in its factories.?

reduce by和reduce to的区别是什么?
reduce by和reduce to的区别是:
1、reduce to用于表示减少的程度。The company must reduce costs to compete effectively.公司要有效地参与竞争必须降低成本。
2、reduce by用于表示减少的数量。Tests indicate this might reduce activity by a factor between 10 an 100.测试结果表明,这可将放射性降低到原来的1/10-1/100。
reduce的用法有:
1、reduce可用作及物动词,也可用作不及物动词。用作及物动词时接名词或代词作宾语。可用于被动结构。
2、reduce偶尔也可接动词不定式作宾语补足语,意思是“使…不得不…”。
3、reduce后常接介词by表示“以某幅度减少”或“以…方法减少”;reduce常接介词to表示“减少到…”或“使陷入…状态”。
4、reduce的过去分词reduced常可用作形容词,在句中作定语。
5、当表达“使……不得不”的意思时,更多采用reduce…to doing(动名词),而很少用动词原形。
reduce to do还是doing
reduce,[ri'dju:s],vt. 减少, 分解。reduce是动词,注意to是介词,后面要接动名词doing。
reduce常用句型:
reduce sb. to doing sth. 使某人沦为做某事
be reduced to doing sth. 使某人沦为做某事
英语学习的方法。
1 学习英语的首要理念:要努力去了解“是什么”,而尽量少去了解“为什么”。
因为英语是语言,很多语汇和句型的用法没有道理可讲,没有“为什么”可言,人们就是这样用的,就是这样说的,记住就好。当然了,仔细分析起来或许可以找到语法上的解释。婴儿时期,我们学说话的时候,从来没有问过“为什么会这么说” 吧,但是为什么后来会说的这么好?因为我们听的多,说的多,自然就记在脑子里了。
2 学习英语的最好方法:背诵课文。
因为英语是我们的后天语言,所以必须将人家现成的东西反复在脑海里形成神经反射,不用关心为什么这样说(同第一点)。
推荐《新概念英语3,4册》。可以说,几乎没有任何一种教材的经典程度超过《新概念英语》。它的语法是最规范的,结构是最严谨的,流传了好几代人,依然保持最为持久的生命力。
3 学习英语需要多种形式的神经刺激。
真正学好英语,不经历背诵大量文章,写大量东西,听大量文章,是根本不可能达到目的的,比如一个新单词,我们在书上看到,默写,背诵,还不能说真正认识了。在听力中听到了这个单词,能反应过来是它吗?在想表达这种意思的时候,能反应过来应该用它吗?……我们当初学说话的时候,都是无形中进行了听,说,读,写等不经意的“练习”才全面掌握了这门语言。
4 学习英语要善于利用零碎时间。
英语学习不是靠突击可以学好的,一下子花上好几个小时拼命学英语,是无济于事的。它的特点在于“细水常流”。每天花上十几分钟的零碎时间听,背一段课文,记几个单词,长期坚持,逐渐会得到提高的。
5 要着意“卖弄”。
新学会的词汇和用法,应该在可能的场合多多练习使用。不要老是用自己喜欢或者熟悉的单词或者句型,这样的话,新学的东西永远得不到强化,慢慢的又会变的陌生,人将会永远停留原有的水平。不断地将新东西变为旧东西,又不断接触新东西,再将其变为旧东西,如此往复,才能不断提高。
好了,今天关于“reduce的用法”的话题就讲到这里了。希望大家能够对“reduce的用法”有更深入的认识,并且从我的回答中得到一些帮助。
