In written English, only is usually placed immediately before the word it qualifies. In spoken English, however, you can use stress to indicate what only qualifies, so its position is not so important. 在书面英语中，only 通常直接置于被修饰词之前。但在口语中，由于可通过重读指示修饰对象，故其位置并不太重要。

1.（表示比较而言唯一真实、恰当或必要的情况）只，只有
You useonly to indicate the one thing that is true, appropriate, or necessary in a particular situation, in contrast to all the other things that are not true, appropriate, or necessary.

e.g. only the President could authorize the use of the atomic bomb...
只有总统才能授权使用原子弹。
e.g. ...the guidance and discipline that can be providedonly by a strong male...
只有强有力的男性才能给予的指导和训练

2.（引出发生的必要条件）只有…（才）
You useonly to introduce the thing which must happen before the thing mentioned in the main part of the sentence can happen.

e.g. The lawyer is paidonly if he wins...
只有官司赢了才支付律师费。
e.g. The Bank of England insists that it will cut interest ratesonly when it is ready...
英格兰银行坚持只有条件成熟才会降息。

3.唯一的；仅有的
If you talk aboutthe only person or thing involved in a particular situation, you mean there are no others involved in it.

e.g. She was theonly woman in Shell's legal department...
她是壳牌公司法律事务部唯一的女性。
e.g. My cat Gustaf was theonly thing I had—theonly company.
我的猫古斯塔夫是我所有的一切——我唯一的伴侣。

4.（孩子）独生的,仅有的
Anonly child is a child who has no brothers or sisters.

Whenonly is used as an adverb, its position in the sentence depends on the word or phrase it applies to. Ifonly applies to the subject of a clause, you put it in front of the subject.only strong characters can make such decisions. Otherwise, you normally put it in front of the verb, after the first auxiliary, or after the verbbe.I only want my son back, that is all.. He had only agreed to see me because we had met before... I was only able to wash four times in 66 days. However, some people think it is more correct to putonly directly in front of the word or phrase it applies to. This is the best position if you want to be quite clear or emphatic.It applies only to passengers carrying British passports... She'd done it only because it was necessary. For extra emphasis, you can putonly after the word or phrase it applies to.The event will be for women only... I'll say this once and once only.
only 用作副词时，其在句中的位置取决于它所修饰的单词或短语。若 only 修饰句子的主语，则置于主语前，如：only strong characters can make such decisions（只有坚强的人才能作出这样的决定）。除去此种情况之外，only 通常置于动词前、第一个助动词或 be 动词之后，如：I only want my son back, that is all（我只想要回我儿子，仅此而已），He had only agreed to see me because we had met before（他同意见我只是因为我们以前见过面），I was only able to wash four times in 66 days（我66天才做到洗了4次澡）。但有人认为将 only 直接置于它所修饰的单词或短语之前更恰当，这样可以表达得更清楚或更具强调意味：It applies only to passengers carrying British passports（这仅适于持英国护照的乘客），She'd done it only because it was necessary（只是出于必要她才这样做的）。若要进一步加强语气，可将only置于它所修饰的单词或短语之后：The event will be for women only（该活动仅限女性参加），I'll say this once and once only（这件事我就说一次，而且仅此一次。）

5.(尤用于想要纠正错误观点时)只不过，仅…而已
You useonly to indicate that something is no more important, interesting, or difficult, for example, than you say it is, especially when you want to correct a wrong idea that someone may get or has already got.

e.g. At the moment it isonly a theory...
眼下这只不过是个推测而已。
e.g. 'I'monly a sergeant,' said Clements...
“我只是一名中士，”克莱门茨说道。

6.（强调数量少或时间短）才，仅仅
You useonly to emphasize how small an amount is or how short a length of time is.

e.g. Child car seatsonly cost about £10 a week to hire.
儿童汽车坐椅一周的租金才10英镑。
e.g. ...spacecraft guidance systems weighingonly a few grams...
仅有几克重的宇宙飞船导航系统

这些仅仅是其中几种可能。
e.g. only a minority of the people supported the Revolution.
只有少数人支持这场革命。

8.（用于 can 或 could 之后，强调除此以外别无可为）只（能）

e.g. For a moment I could say nothing. I couldonly stand and look...
我有那么一会儿一句话都说不出来，只能站在那里看着。
e.g. The police canonly guess at the scale of the problem.
警方只能猜测问题的严重性。

9.（强调希望或愿望）唯有，非常
You can useonly in the expressionsI only wish orI only hope in order to emphasize what you are hoping or wishing.

e.g. Ionly wish he were here now that things are getting better for me...
现在我的境况好转了，我真希望他能在这里。
e.g. We canonly hope that the elephants can recover.
我们唯有希望这些大象能够康复。

10.（用于表示稍加改动或限定）只是，不过
only can be used to add a comment which slightly changes or limits what you have just said.

only是什么意思

e.g. It's a bit like my house,only nicer...

e.g. We haveonly to read the labels to know what ingredients are in foods.

adj.(形容词)

1. only用作形容词表示“唯一的,仅有的”,可修饰单数名词,也可修饰复数名词。前面常加定冠词the或形容词性物主代词。
2. 当only与另一个形容词或数词连用时, only要放在它们前面。
3. only除用于表示“独生子女”外,一般不用在不定冠词an之后。

adv.(副词)

1. only用作副词时,意思是“只,仅仅,才”。only还常用在名词短语之前,尤其是用在以数量词或数字起始的名词短语之前,起强调作用。
2. only后可加动词不定式结构作结果状语,表示“不料,结果却”,多用于意外和不幸的场合。如果“only+动词不定式”的结构较长,可用逗号与前面的成分隔开。
3. “only+ v -ing”结构也可用作结果状语,通常表示一个自然的或意料之中的结果,意为“结果(只)是”,其前一般用逗号与前面的成分隔开。
4. only位于句首并修饰句子的状语时,后面的句子要倒装。
5. only用于将来时常常预示着不好的或不如意的事情发生。

adj.(形容词)

only, single, sole

这三个词都有“唯一的”意思。其区别在于：

1.single的意思是“单一的,单个的”,指不伴随、不依傍、不参与其他事物。

2.only与单数可数名词连用时意思是“唯一的”,与复数名词连用时意思是“仅有的”。例如:

That is the only fault to be found with him.那是他身上挑得出来的唯一毛病。

We were the only women there.那儿的女生只有我们几个。

3.sole强调“单独的”,而且只考虑到单独的一个。例如:

The sole survivor of the crash was a little baby.这次撞车的唯一幸存者是一个婴儿。

He is the sales representative with sole responsibility for sales in the North East.他是负责东北地区销售业务的销售代表。

4.语义上, sole>single>only。

adv.(副词)

only, alone

这两个词意思相同,常常可以通用,例如：

He knew it was impossible to accomplish it by individual effort only〔alone〕.他知道只靠个人努力是不能完成那件工作的。

它们之间的区别是：

1.在句中的位置不同：alone通常要放在它所修饰的词语之后,而only却可置于其前。例如：

只有他才能做这件事。

He alone can do it.

only he can do it.

2.含义上也有区别：alone表示只此一个,别无其他,相当于exclusively; 而only则暗示所指的事物有所限制,相当于solely。例如：

Our farm alone sold 80,000 kilograms of wheat.

单是我们农场就出售了八万公斤小麦。

only our farm sold 80,000 kilograms of wheat.

只有我们农场出售了八万公斤小麦。

第一句暗指其他农场也出售了这么多甚至更多; 而第二句则暗指其他农场没有我们多。再如：

They alone sell cotton clothing.

他们独家出售棉布服装。

They only sell cotton clothing.

他们只售棉布服装。(不售丝绸)

下面三句的意思不同:

only Mary liked Joe.

只有玛丽喜欢乔。(别人不喜欢乔)

Mary only liked Joe.

玛丽仅仅喜欢乔。(但不爱他)

Mary liked only Joe.

玛丽只喜欢乔一个人。(不喜欢别人)

only，single，sole，unique，alone

这些形容词均可表示“唯一的”之意。

only普通用词，常可与sole换用，但侧重仅限于指定的人或物，而不需要更多。

single语气较强，强调仅此一个，再无第二个。

sole语气强于only，指仅有一个或一群，只考虑这一个或这一群。

unique非正式用词，侧重在一类中唯一无可匹敌、无与伦比的特征。

alone着重专指某人或某物，而不是别的。
