under discussion和on discussion 哪个表示“在讨论中”?
on discussion 和 under discussion 都可表示“在讨论中”，都是固定搭配(都用介词on且都不用冠词)。请问它们有区别吗?
在下列工具书中只有under discussion，没有on discussion。
1. 郭杰克主编《当代英语搭配大词典》(高等教育出版社 11月第1版)P459:
Their case is under discussion.
2. 简清国主编《建宏?外研社英汉多功能词典》(外语与教学研究出版社1月第1版)P422:
the question under discussion
3. 王文昌主编《英语搭配大词典》(江苏教育出版社1991年1月第1版)P495:
That’s another topic that will come under discussion.
Don’t deviate from the subject under discussion.
4. 张道真编著的《现代英语用法词典》(重排本) (外语教学与研究出版社1994年10月第1版) P348:
be [come] under discussion
The question is still under discussion.
That has no relation to the matter under discussion.
That’s another topic that came under discussion.
5. 周国珍主编的《大学英语详注词典》(上海交通大学出版社 209月第一版)P324:
under discussion
Their case is now under discussion.
6.《柯林斯COBUILD高阶英汉双解学习词典》(外语教学与研究出版社 7月第1版)P737:
If something is under discussion, it is still being talked about and a final decision has not yet been reached.
“The proposals are still under discussion,” she said.
7.《麦克米伦高阶英汉双解词典》 (杨信彰等译 外语教学与研究出版社 10月第1版 )P577:
be under discussion(=being discussed)
Proposals for changing existing system are currently under discussion.
8. Longman Dictionary of Contemporary English(English?Chinese) (Fourth Edition) (光盘版):
under discussion(=being discussed)
the project is under discussion as a possible joint venture.
9.《牛津高阶英汉双解词典》(第7版) (商务印书馆 4月第3版) P569:

10.(日) 市川繁治郎主编《英语搭配大辞典》(外语教学与研究出版社10月第1版) P523:
under discussion
The bill, then under discussion in committee, seemed doomed to die before reaching the Senate floor.
另外，在英美国家的语料库中也极少有on discussion的真实例证。
①在BNC 上共有247例包含 under discussion 的例句，但仅有一例包含 on discussion 的例句：
I'm not seeking to close down on discussion about item three, one and three, three but in view of the discussion we took this morning,…
② 在COCA 共有403例包含 under discussion 的例句，但仅有一例包含on discussion的例句：
Person centered planning activities had a positive effect on parent participation in IEP/TP meetings, but not on discussion of post-school issues during the meetings.
由此看来，under discussion 表示“在讨论中”是正确的表达形式;on discussion虽不能说绝对错误，但在英国英语和美国英语中几乎没有人使用。
介词below与under的用法区别
1. 两者都可表示“低于”，under 主要表示垂直在下的正下方，而 below 则不一定表示正下方(即可以是正下方或非正下方)。如：
Look in the cupboard below [under] the sink. 到洗碗池下面的柜子里找一找。
The climbers stopped 300 meters below the top of the mountain. 登山队员们在离山顶 300 米处停了下来。
换句话说，表示正下方，两者都可用;不表示正下方，则通常用below。
2. 两者均可表示数量方面的“少于”，但在现代英语中，以用 under 为多见。如：
He can't be much below [under] sixty. 他的年龄不可能比 60 岁小很多。
There were under forty people at the meeting. 参加会议的人不足 40 人。
It took us under an hour. 我们用了不到 1 个小时。
注：在现代英语中，below 表示“少于”，主要用于表示温度、高度以及有纵向标准可比的情况。如：
This place is below sea level. 此地在海平面以下。
The temperature is two degrees below zero. 温度是零下 2 度。
3. 若表示一物被另一物所覆盖，则通常用 under。如：
She crept in beside him under the bedclothes. 她钻进被窝躺在他身旁。
4. 表示职位、级别等关系时，用 under 表直接关系，用 below 表非直接关系。比较：
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 先生职位低。
立竿见影：immediately的用法辨析

conj.
一...(就)

一吃完茶点，他就匆忙起身外出。
二、词义辨析：哪些副词能形容“马上”
immediately, instantly, presently, directly, shortly, soon, at once, right away
这些副词或副词词组均有“立刻，马上”之意。
immediately指做完一件事后，立即就做另一件事，中间一般没有明显的时间间隔。
instantly指恰恰就在此刻，一秒钟也没耽误。
presently指不久、即将。
directly和immediately同义，指毫无迟疑。
shortly和soon同义，指动作发生或完成的速度之快。
soon常用词，指行动快，完成速度快。
at once口语中常用，语气强烈，指时间紧迫，一刻也不能耽误。
right away主要用于美国英语，语气稍弱于at once，强调动作迅速。

以上译法均正确，如果你都会，而且一目了然，建议跳过，别浪费你宝贵的时间，如果还赶脚有点夹生，那么请继续看：
worth，?worthy，?worthwhile?这三个词均可表示“值得的”，由于它们词形相近，意义相似，所以许多同学经常将其用混。它们的用法区别：
一、从句法功能上看
从句法功能上看:
worth?通常只用作表语，不用于名词前作定语;
worthy?和?worthwhile?可用作表语和定语。如：
This second-hand car is worth $ at the most.
The exhibition is worth a visit/visiting.
It?isn‘t?worth?the?trouble.?不值得费那个事。
This phenomenon is worthy of being studied.这种现象值得研究。
That is worthy of note.那件事值得注意。
He?is?a?worthy?gentleman.?他是位值得尊敬的绅士。
His?behavior?is?worthy?of?great?praise.?他的行为值得高度赞扬。
They?achieved?a?very?worthwhile?result.?他们取得了很有价值的成果。
We?had?a?long?wait，?but?it?was?worthwhile?because?we?got?the?tickets.?我们等了很久，但还算值得，因为我们把票买到了。
二、从所使用的修饰语来看
worth?习惯上不用?very?修饰(要表示类似意思可用?well)，而?worthy?和?worthwhile?则可以用副词very修饰。如：
That?is?very?worthy?of?our?attention.?那件事很值得我们注意。
Nursing?is?a?very?worthwhile?career.?护理工作是很值得干的职业。
但习惯上不说：The?work?is?very?worth?doing.?(very?应改为?well)。
三、从搭配习惯来看
有关?be?worth?的搭配习惯
(1)?be?worth后可直接跟名词、代词或动名词。如：
The?picture?is?worth?$?500.?这幅画值500?美元。
The?clock?is?hardly?worth?repairing.?这台钟简直不值得修理。
What?is?worth?doing?is?worth?doing?well.?值得干的事就得干好。
注意：其后可接动名词，不能接不定式，且接动名词时，总是用主动形式表示被动意义。
(2)?在现代英语中，在be?worth前使用形式主语it被认为是合习惯的。如：
It?isn‘t?worth?repairing?the?car.?这辆汽车不值得修了。
Is?it?worth?visiting?the?city??这个城市值得去看吗?
但是，若不用形式主语it而直接用动名词作主语则是错误的，如：误：Repairing?the?car?is?worth.
(3)?在be?worth?doing?结构中，除非句首用了形式主语it，否则句子主语总应是其动名词的逻辑宾语;若其中的动词不及物，应考虑加上适当的介词。如：Nothing?he?said?was?worth?listening?to.?他说的话没有一句值得听。
She’s?not?worth?getting?angry?with.?犯不上跟她生气。
2.?有关?be?worthy?的搭配习惯
(1)?be?worthy?后不能直接跟名词、代词或动名词，若要接，应借助介词?of.如：Their?efforts?are?worthy?of?your?support.?他们的努力应得到你的支持。?Her?behavior?is?worthy?of?praise.?她的行为是值得赞扬的。
(2)?与be?worth后只接动名词不接不定式不同，be?worthy后不接动名词，而接不定式(若该不定式要表示被动意义，则应用被动形式)。如：
He?is?worthy?to?receive?such?honor.?他应该得到这种荣誉。
This?suggestion?is?worthy?to?be?considered.?这个建议值得考虑。
(3)?若要在be?worthy后接动名词，与后接名词时的情形一样，应借助介词of，且该动名词若要表示被动意义，要用被动形式。如：
He?is?worthy?of?filling the?post.?这个职位他当之无愧。
This?suggestion?is?worthy?of?being?considered?[= This?suggestion?is?worthy to?be?considered].?这个建议值得考虑。
3.?有关?be?worthwhile?的搭配习惯的搭配习惯
(1)?be?worthwhile?后接动名词或不定式均可。如：
It?is?worthwhile?buying?the?dictionary.?这本词典值得买。(其中的?worthwhile?也可换成?worth，但不可以换成worthy)
It?is?worthwhile?to?discuss?the?plan?again.?这个计划值得再讨论一次。(worthwhile?不能换成?worth，因为其后接用了不定式,但可以换成worthy)
(2)?有时可将worthwhile分开写，此时也可在其中加上one‘s.如：I’d?think?it?worth?while?to?go.?我认为值得去。
The President's trip to Washington this week seems to have been worthwhile
总统本周的华盛顿之行看来是有价值的。
It is worth while paying a vistlt to the great wall.

and和or的用法：
1、and和or的用法并列结构中，or通常用于否定句，and用于肯定句。但有时and 也可用于否定句。
2、在否定中并列结构用or 连接，但含有两个否定词的句子实际被看作是肯定结构，因此要用and。
3、or用于连接并列的单词、词组、短语或句子,表示“或者”的意思。or用在选择疑问句中,灵活译为“还是”。or用于否定句中,代替and ,表示“和”的意思。
4、or用于连接两个并列的句子,表示“否则,要不然”的意思。

篇10：on用法总结
（2）on表示地点、位置,有“在.旁”、“接近”、“靠近”之意.如：
a house on the main road 临大街的房子,sit on my right 坐在我的`右边
（3）on表示状态,译为“处于.情况中,从事于.”等.如：
on duty 值日,on holiday 度假
（4）on表示“在.上面”,用在表示物体的名词前.如：
on the box 在盒子上
on和over都是介词,on表示“在.上面”,指一物体与另一物体表面相接触；over表示“在.上方”,指一物体与另一物体不接触.试比较：
There is a light on the desk．桌子上有盏台灯.（light与desk接触）
There is a light over the desk．桌子上方有一盏灯.（light与desk不接触）
表示“在.上”,介词on与in必须注意习惯用法,否则会出错.不妨比较一番：
on the tree／in the tree都译为“.在树上”.前者表示树上本身所长着的叶子、花、果实等；后者表示某物或某人在树上.
on the wall／in the wall都译为“在墙上”.由于介词不同,在使用上有区别.图画、黑板、风筝等“在墙上”,是因为它们在墙的表面上,故用on the wall；门窗、钉子、洞、孔等“在墙上”,是因为它们在墙的里面,故用in the wall.

篇12：THAT用法总结
“that”在英文中是一个使用频率很高的单词。它有四种词性，并且句法及语法功能纷繁复杂。同学们如果不能熟练掌握其用法，很可能会形成英语学习的一种障碍，从而影响其学习兴趣和效率。现将that的用法总结归纳如下：
第一、that 用作形容词（后接复数名词时用those）。
它用来指已被提到的人或物；也可表对比，指两个中较远的那个。
what about that book you borrowed from me last month？
请注意，that 有时候在句子中具有喜欢或轻蔑等感情色彩。
that little son of his 他那个小宝贝儿子
that george！乔治那家伙！（含有轻蔑语气）
第二、that 用作代词。
1. that 用作指示代词（复数形式是those），其指代意义同形容词用法，同时它还可以用作定语从句中的先行词；还可为了避免重复，代替前述名词。
that is what he told me.
what is that (which) you have got in your hand?
the price of rice is higher than that of flour.
2. that 用作关系代词，引导限制性定语从句。先行词可人可物，用法相当于who或which。（但是在下列情况下多用that：先行词既有人又有物时；先行词有形容词最高级、序数词、不定代词、very，only等修饰时；先行词是不定代词时）
he talked about the teachers and schools that he had visited.
i think it one of the most wonderful films that the film company has ever produced.
she has little information that is useful for our research.
is there anything that i can do for you?
请注意，that 在定语从句中作宾语时通常可省略。
the books (that) i sent you will help you in your studies.
第三、that 用作连词，引导名词性从句,状语从句和强调句。
1. that名词性从句。
①引导宾语从句。及物动词后的引导词that可省略。
i didn't expect (that) he could win the championship.
the teacher pointed out that tom was not working hard enough.
② 引导主语从句。通常采用it作形式主语的句型。
that the earth goes around the sun is known to everyone.
（it is known to everyone that the earth goes around the sun.）
③引导表语从句。
the trouble is that we are short of money.
④引导同位语从句。
引导同位语从句的that和引导定语从句的that是不同的。前者只起语法作用，在从句中不作任何成分；而后者在定语从句中作主语、宾语或表语。举例说明：
the news that he resigned from office surprised us.
the idea that he holds is very common nowadays on campus.
2. that引导状语从句
①引导目的状语从句。
bring it nearer that i may see it better.
②引导结果状语从句。
what have i done that he should be so angry with me?
③引导原因状语从句。
i am afraid that i will fail in the driving test.
④引导让步状语从句。意为“虽然、尽管”。
difficult that/as the task was, they managed to accomplish it on time.
⑤引导条件状语从句。意为“假使、假设”。
supposing that you were in my position, what would you do?
on condition that you were lost in the desert, you should ask for help as soon as possible.
3. 引导强调句。
it is mrs. white that makes the decision in her family, not her meek little husband.
it is an ill wind that blows nobody good.
第四、that用作副词。
1. that用作普通副词。
i was that/so angry i could have hit him.
2. that用作关系副词。引导定语从句，可以代替when，where， why或 in which，常可省略。
i will never forget the evening (that) / when we went to the theatre.
the house (that)/where i used to live has been knocked down.
第五，与that 有关的常见重要短语。
1. in that，意为“既然、因为”。
criticism and self-criticism is necessary in that it helps us correct our mistakes.
2. now that，意为“既然、由于”。
now that they have taken matters into their hands, the pace of events has quickened.
3. see (to it) that，意为“注意、务必做到、保证”。
we will see to it that she gets home early.
see to it that you are not late again.
4. seeing that，意为“鉴于、由于”。
seeing that it is 8 o'clock, we'll wait no longer.
seeing that he was busy with his work, i didn't disturb him.
篇13：as用法总结
一)as作副词，表示程度，意为“同样地”。在“as...as...”，“not as...as...”结构中的第一个as是副词，作“和/与...(不)一样”解。eg：
Jack is as tall as his father.杰克和他的父亲一样高。
He doesn't speak English as/so fluently as you.他的英语说得不如你流利。
二)as作介词。
1.作“如，像”解。eg：
They got united as one man.他们团结得像一个人一样。
2.作“充当，作为”解。eg：
As a writer，he was famous.作为作家，他是很有名的。
三)as作连词，常用来连接主句和状语从句。
1.引导时间状语从句，作“当...的时候”解，有“随着...”之意，与while意义相近，强调两个动作同时发生;或某事一发生，另一事立即发生。eg：
He shouted aloud as her ran along.他一边往前跑，一边高声地呼喊。
I was startled as he opened the door.他一开门，我吓了一跳。
as作连词，相当于when。eg;
As a little boy (When he was a little boy)he began to learn to play piano.他小时候就开始学弹钢琴。
2.引导原因状语从句，作“因为，由于”解，与because的用法相近。eg;
I must stop writing now，as I have rather a lot of work to do.我必须停笔了，因为我还有许多工作要做。
3.引导方式状语从句或比较状语从句，作“正如，(如)像”解。例eg：
As in your country，we grow wheat in the north and rice in the south.正如(像)你们国家一样，我们在北方种小麦，在南方种大米。(方式状语从句)
When at Rome，do as Romans do.入乡随俗。(方式状语从句)
4.引导让步状语从句，作“虽然，尽管”解。这时从句常用倒装语序，即把从句中的表语、状语或动词原形放在as之前。eg;
Strange as it may seem，it is true.尽管这事看上去很奇怪，但却是真的。
Try as he might，Tom could not get out of the difficulties.不管怎样努力，汤姆还是摆脱不了困境。
四)as作关系代词。
1.引导限制性定语从句，用在“such...as”,“the same...as”，“as...as”等结构中，常译作“像...一样的人(或物)”，“凡是...的人(或物)”。例eg：
He wished to be such a man as Lei Feng was.他曾希望做一个像雷锋那样的人。
My hometown is no longer the same as it was.我的家乡再也不像过去一样了。
2.引导非限制性定语从句，用来指代它前面的整个句子(即先行句)，意思是“这一点”。这个分句可以位于句首、句中或句末。eg：
As is well known，oceans cover more than 70% of the earth.我们知道，海洋占地球面积的百分之七十以上。
篇14：that用法总结
that还常用以代替who, whom, which,但that...which中的that用做关系代词的先行词。
that可以用作连词
that用作连词时可引导主语从句、宾语从句、表语从句、同位语从句和状语从句。
that还常引导间接引语或形容词后面的.从句。
that在以it作形式主语的句子中或引导宾语从句、状语从句时常可省略。
篇15：as if 用法总结
从句表示与将来事实相反，谓语动词用“would／could／might＋动词原形”。
例句：
You look as if you didn’t care.
你看上去好像并不在乎。
He talks about Rome as if he had been there before.
他说起罗马来好像他以前去过罗马似的。
He opened his mouth as if he would say something.
他张开嘴好像要说什么。
