as for 加詞。as to 加句子。

as for (至於,就……方麵說)和 as to (至於；關於)這兩個複合介詞在含義上相當接近,但在用法上差別很多.下麵談它們的這些差別.

1．as for

1)用以轉換話題：在有前文的情況下as for總是出現在下文的句首,用來引出另外一方或者新的談話內容,但與前文內容也有一定的聯係,起到補充前文又突出後文的作用,使之與前文形成對照,譯作“至於”.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)用以表現態度：as for還可以用來表示講話人對某人或某物持有“輕蔑”或“冷淡”的態度,甚至有憎惡之感,講話時要重讀引出的詞語並在其後稍作停頓,以示強調,口氣上帶有嘲諷意味,譯作漢語的“至於……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)表示涉及某點：as to常放於句中,表示“關於……方麵”、“有關……之事”,但為了突出要提及的人或事之時,也可將as to置於句首,以示強調.但隻涉及內容,而不涉及講話人的態度.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)用以重提舊事：as to引出的內容都是前文曾經提到過的或者談話對方都有所了解的,表示“說到”之義.,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)用於提出問題：as to必須位於句中,前麵出現的大都是表達某種心理活動的動詞,形容詞或名詞,其後引接出wh-clause或who-to-v結構,表示“在……的問題上”、“就……問題來講”,所引出的問題都有很強的針對性.但有人認為這裏的罄to顯得多餘,去之亦通.所以,有時也不必譯出.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)引出做事的依據：as to還有“按照”、“根據”的含義,而as for則無此義.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．

綜上所述,as for 和 as to在確切含義的表達和具體用法上都是有很大差別的,不能將二者混為一談.

＂such as＂後麵可以接句子嗎？

such as 可以加句子嗎

for example就把他當成是插入語，句子結構不回受到這個插入語的影響，而such as可你把他理解成一個介詞的作用，介詞後麵接名詞，動名詞。

For example, BBC broadcasts English programmes for China with explanations in Chinese. 例如，BBC對中國廣播的英語節目配有漢語解釋。

English is spoken in many countries, such as Australia and Canada. 許多國家都講英語，例如澳大利亞和加拿大。

由此可見， for example 可帶句子， 而such as 不行。

l)for example強調“舉例”說明，而且一般隻舉同類人或物中的一個作為插入語，且用逗號隔開，可置於句首、句中或句末。

如：Many people here, for example, John, would rather have coffee.這裏有許多人，例如約翰很喜歡喝咖啡。

There are many kinds of pollution, for example, noise is a kind of pollution.有許多種汙染方式，例如噪音就是一種汙染。

2)such as用來“羅列”同類人或物中的幾個例子，可置於被列舉的事物與前麵的名詞之間，但其後邊不能用逗號。

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

【非虛擬語氣】He talked as if he had seen the accident.他講話的感覺是他好像看見這事故。

【虛擬語氣】簡明釋義as if好像， 似乎， 仿佛；恍；宛然；恍若as if網絡釋義1. 好像2. 猶如3. 好似4. 宛若5. 如臨深淵用法as if 從句的作用1.引導表語從句， 常與as,look, seem,feel,taste,smell,sound等係動詞連用。

如：She looks as if she were ten years younger.她看起來好像年輕了十歲。

It seems as if our team is going to win.看來我們隊要勝了。

It looks as if a tornado swept through your room.好像有龍卷風席卷過你的房間。

2. 引導方式狀語從句，表示“事情是怎麼做的”或“一個人或事物是什麼樣的”。

如：She loves the boy as if she were his mother.她愛這男孩，就好像她是他的媽媽一樣。

The child talked to us as if he were a grown-up.那孩子跟我們談起話來，像個成年人似的。

She spoke to me as if she knew me.她和我說話的神情，好像她早就認識我。

You answered the question as if you did not know this rule.你回答的問題好像不知道這個規則似的。

as if 還可用於省略句中如果as if 引導的從句是“主語+係動詞”結構，可省略主語和係動詞，這樣as if 後就隻剩下名詞、不定式、形容詞（短語）、介詞短語或分詞。

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

Tom raised his hands as if (he was going) to say something.湯姆舉起手好像要說什麼。

當說話者認為句子所述的是真實的或極有可能發生或存在的事實時。

如：It sounds as if it is raining.聽起來像是在下雨。

He talks as if he is drunk.從他談話的樣子來看他是醉了。

The boss speaks aloud as if he is angry.老板說話聲音很高，好像他真的生氣了。

2.as if 從句用虛擬語氣的情況。

當說話人認為句子所述的是不真實的或極少有可能發生或存在的情況時。

從句虛擬語氣動詞時態的形式如下：（1）如果從句表示與現在事實相反，謂語動詞用一般過去時。

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

He talks as if he knew where she was.他說話的樣子，好像他知道她在哪裏似的。

When a pencil is partly in a glass of water,it looks as if it were broken.當一支鉛筆部分地放在水中時，它看上去像是折斷了。

（2）從句表示與過去事實相反，謂語動詞用“had+過去分詞”。

如：He talks about Rome as if he had been there before.他說起羅馬來好像他以前去過羅馬似的。

The girl listened as if she had been turned to stone.那女孩傾聽著，一動也不動，像已經變成了石頭似的。

Everythings in my childhood crowded in my mind as if they had just happened.童年發生的一切都擠在我的腦海，仿佛就像剛剛發生的一樣。

如：He opened his mouth as if he would say something.他張開嘴好像要說什麼。

It looks as if it might snow.看來好像要下雪了。

（4）as if 後麵可以接陳述語氣和虛擬語氣，如果句子的情況是真實的，那麼隻要保持時態一致即可，如果後麵接的並非真實情況，則要按照虛擬語氣規則把句子形式改變（簡單說就是時態倒退原則）。

（5） as if 在俚語中能表示反諷，功能類似＂like＂，舉例：As if / Like you are going to do the dishes;＂like＂不能獨立成句，但as if 能（完整句子為：as if that/it is true.），例子：甲：She said she would help me with the project. 乙：As if!(6)談論過去情形的動詞形式有以下幾種：a）過去式，表示過去的狀態，如：He looked at me as if I were mad. 他那樣看我，好像我是個瘋子。

He stood there looking at the train and laughing, as if to miss a train was the best joke in the world.他站在那裏，望著火車哈哈大笑，好像誤了火車是天底下最開心的事兒似的。

Mr. Coleman always talked as if he knew everything.但是，如果狀態動詞帶有持續時間狀語，則用過去完成時：They talked as if they had been friends for years. （高二冊，第95頁）Now it is as though she had known Millie for years. （《現代英語用法詞典》）情態動詞亦用過去時：She felt as though she could hardly endure such a life.她覺得簡直無法忍受這樣的生活。

b）過去完成時，表示過去的動作先於主句動詞而發生或完成，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.”（高二冊，第91頁）必須注意的時，在指過去的動作時，即使主句是現在時，as if 從句中的動詞也要用過去完成時：You look as if you'd seen a ghost. 你好像是見了鬼似的。

He talks about Rome as though he had been there himself.他講起羅馬的情況來就好像他親自到過那...
