◆as prep, conj. & pron.

1. 用作介詞，意為“作為”、“當(dāng)作”、“充當(dāng)”。如：

2. 用作連詞，注意以下用法：

(1) 表示“隨著”。如：

若其后不接從句，而接名詞，則用介詞 with 表示“隨著”。如：

(2) 表示讓步(意為：雖然，盡管)，要用于倒裝句(相當(dāng)于 though, 但語(yǔ)氣稍弱)。如：

Try as he would [might]，he couldn’t open the door. 他試過(guò)多次了，卻仍打不開(kāi)門(mén)。

注：倒裝后位于句首的名詞通常不用冠詞。如：

3. 用作關(guān)系代詞，主要用法有：

Such people as knew him admired him. 認(rèn)識(shí)他的人都?xì)J佩他。

He smokes as expensive a cigarette as he can afford. 他抽一種他買(mǎi)得起的最貴的煙。

(2) 單獨(dú)用作關(guān)系代詞，引導(dǎo)非限制性定語(yǔ)從句，可放在主句之前(常譯為：正如)或之后(常譯為：這一點(diǎn))，且主從句之間一般要用逗號(hào)隔開(kāi)。如：

He was absent, as is often the case. 他缺席了，這是常有的事。

◆ask v.

有時(shí)雙賓語(yǔ)交換位置，借助介詞 of。如：

正：He came to ask me a favour.

正：He came to ask a favour of me.

(3) 與 after 連用，表問(wèn)候或問(wèn)好。如：

你問(wèn)候。

比較：
