as for 加词。as to 加句子。

as for (至于,就……方面说)和 as to (至于；关于)这两个复合介词在含义上相当接近,但在用法上差别很多.下面谈它们的这些差别.

1．as for

1)用以转换话题：在有前文的情况下as for总是出现在下文的句首,用来引出另外一方或者新的谈话内容,但与前文内容也有一定的联系,起到补充前文又突出后文的作用,使之与前文形成对照,译作“至于”.例如：

①You have a bed；as for him,he'll have to sleep on the floor．

②Much pasture land is underwater；and as for the grain, most of that has been ruined．

2)用以表现态度：as for还可以用来表示讲话人对某人或某物持有“轻蔑”或“冷淡”的态度,甚至有憎恶之感,讲话时要重读引出的词语并在其后稍作停顿,以示强调,口气上带有嘲讽意味,译作汉语的“至于……嘛”.例如：

①As for you,I never want to see you here in my home again．

②As for his songs,I suppose you've read the sarcastic reviews !

2．as to

1)表示涉及某点：as to常放于句中,表示“关于……方面”、“有关……之事”,但为了突出要提及的人或事之时,也可将as to置于句首,以示强调.但只涉及内容,而不涉及讲话人的态度.例如：

①His wife,an old teacher,has no complaint as to salary．

②As to your ability to overfulfil the target,I never had the slightest doubt．

2)用以重提旧事：as to引出的内容都是前文曾经提到过的或者谈话对方都有所了解的,表示“说到”之义.,例如：

①As to doing that,I haven't decided yet．

②As to the question you raised in your last letter,I think that it is unanswerable．

3)用于提出问题：as to必须位于句中,前面出现的大都是表达某种心理活动的动词,形容词或名词,其后引接出wh-clause或who-to-v结构,表示“在……的问题上”、“就……问题来讲”,所引出的问题都有很强的针对性.但有人认为这里的罄to显得多余,去之亦通.所以,有时也不必译出.例如：

①There is some doubt as to whether the proposal is practicable．

②I enquired of the clerk as to which documents were needed．

4)引出做事的依据：as to还有“按照”、“根据”的含义,而as for则无此义.例如：

①The shoes are correctly placed on the shelf as to size and colour．

②The items on the agenda are listed as to order of importance．

综上所述,as for 和 as to在确切含义的表达和具体用法上都是有很大差别的,不能将二者混为一谈.

＂such as＂后面可以接句子吗？

可以1 They are already battling to eradicate illnesses such as malaria and tetanus.2 The wind such as flower of time, and you become the most beautiful ornament.3 America wants to eliminate tariffs on items such as electronics.4 Wild flowers such as orchids and primroses are becoming rare.5 The end of the summer, the who. Memory such as a line, who stumbled.6 Idle such as vinegar, can soften the spirit of the calcareous; diligent like alcohol, can burn the flame of wisdom.7 His faith that men such as the Reverend John Leale tried to do their best is unshaken.8 Avoid unhealthy foods such as hamburger and chips.9 The risk of infection is confined to groups such as medical personnel.10 Many polymers, such as nylon, are artificial.11 Several offences such as manslaughter may be committed by omission.12 Playing together teaches children social conventions such as sharing.13 You're welcome to borrow my tennis racket, such as it is.14 They were made to listen to white noise,[www.Sentencedict.com] such as static of the sort you might pick up between radio stations.15 Some strong alcoholic drinks such as whisky are made by distilling.

such as 可以加句子吗

for example就把他当成是插入语，句子结构不回受到这个插入语的影响，而such as可你把他理解成一个介词的作用，介词后面接名词，动名词。

For example, BBC broadcasts English programmes for China with explanations in Chinese. 例如，BBC对中国广播的英语节目配有汉语解释。

English is spoken in many countries, such as Australia and Canada. 许多国家都讲英语，例如澳大利亚和加拿大。

由此可见， for example 可带句子， 而such as 不行。

l)for example强调“举例”说明，而且一般只举同类人或物中的一个作为插入语，且用逗号隔开，可置于句首、句中或句末。

如：Many people here, for example, John, would rather have coffee.这里有许多人，例如约翰很喜欢喝咖啡。

There are many kinds of pollution, for example, noise is a kind of pollution.有许多种污染方式，例如噪音就是一种污染。

2)such as用来“罗列”同类人或物中的几个例子，可置于被列举的事物与前面的名词之间，但其后边不能用逗号。

如： I have travelled many cities such as Bei jing,Shang hai, and Guangzhou.

如：She looks as if she were ten years younger.她看起来好像年轻了十岁。

You answered the question as if you did not know this rule.你回答的问题好像不知道这个规则似的。

as if 还可用于省略句中如果as if 引导的从句是“主语+系动词”结构，可省略主语和系动词，这样as if 后就只剩下名词、不定式、形容词（短语）、介词短语或分词。

如：He acts as if (he were) a fool.他做事像个傻子。

Tom raised his hands as if (he was going) to say something.汤姆举起手好像要说什么。

2.as if 从句用虚拟语气的情况。

当说话人认为句子所述的是不真实的或极少有可能发生或存在的情况时。

从句虚拟语气动词时态的形式如下：（1）如果从句表示与现在事实相反，谓语动词用一般过去时。

如：You look as if you didn' t care.你看上去好像并不在乎。

He talks as if he knew where she was.他说话的样子，好像他知道她在哪里似的。

When a pencil is partly in a glass of water,it looks as if it were broken.当一支铅笔部分地放在水中时，它看上去像是折断了。

（4）as if 后面可以接陈述语气和虚拟语气，如果句子的情况是真实的，那么只要保持时态一致即可，如果后面接的并非真实情况，则要按照虚拟语气规则把句子形式改变（简单说就是时态倒退原则）。

（5） as if 在俚语中能表示反讽，功能类似＂like＂，举例：As if / Like you are going to do the dishes;＂like＂不能独立成句，但as if 能（完整句子为：as if that/it is true.），例子：甲：She said she would help me with the project. 乙：As if!(6)谈论过去情形的动词形式有以下几种：a）过去式，表示过去的状态，如：He looked at me as if I were mad. 他那样看我，好像我是个疯子。

b）过去完成时，表示过去的动作先于主句动词而发生或完成，如：It was as if he had lost his last friend. “I remember,” she tells her children now, “how wild his whitehair looked——as if it had been electrified.”（高二册，第91页）必须注意的时，在指过去的动作时，即使主句是现在时，as if 从句中的动词也要用过去完成时：You look as if you'd seen a ghost. 你好像是见了鬼似的。
