1. 用作介詞，意為“作為”、“當作”、“充當”。如：
He treats me as a child. 他把我當小孩看待。
As your doctor, I advise you to eat less. 作為你的醫生，我建議你少吃點。
2. 用作連詞，注意以下用法：
(1) 表示“隨著”。如：
As time passed, things seemed to get worse. 隨著時間的推移，情況似乎變得更糟了。
若其后不接從句，而接名詞，則用介詞 with 表示“隨著”。如：
With the development of modern agriculture and industry, more and more waste is produced. 隨著現代工農業的發展，污染越來越嚴重了。
(2) 表示讓步(意為：雖然，盡管)，要用于倒裝句(相當于 though, 但語氣稍弱)。如：
Much as I like you, I couldn’t live with you. 我盡管很喜歡你，卻不能和你一起生活。
Try as he would [might]，he couldn’t open the door. 他試過多次了，卻仍打不開門。
注：倒裝后位于句首的名詞通常不用冠詞。如：
Boy as he was, he behaved like a girl. 他雖然是個男孩，但舉止卻像個女孩。
3. 用作關系代詞，主要用法有：
(1) 用在 such, same, as 等之后，引導限制性定語從句。如：
I live in the same place as Tom does. 我和湯姆住在同處。
Such people as knew him admired him. 認識他的人都欽佩他。
He smokes as expensive a cigarette as he can afford. 他抽一種他買得起的最貴的煙。
(2) 單獨用作關系代詞，引導非限制性定語從句，可放在主句之前(常譯為：正如)或之后(常譯為：這一點)，且主從句之間一般要用逗號隔開。如：
He was absent, as is often the case. 他缺席了，這是常有的事。
As was expected, he succeeded at last. 正如我們所料，他終于成功了。
◆ask v.
1. 可以接雙賓語。如：

有時雙賓語交換位置，借助介詞 of。如：

正：He came to ask me a favour.

他問了我一個問題。
正：He asked me a question.
正：He asked a question of me.

(1) 與介詞 for 連用，有“要求得到”的意思。如：
She is always asking for money. 她老是要錢。
He asked 100 yuan for a box. 他要100元一箱。
有時單獨用 ask 也可表示 ask for 的意思。如：
He asked (for) the teacher’s advice. 他向老師征求意見。
=He asked the teacher for his advice. 他向老師征求意見。
(2) 與 about 連用，表示詢問或打聽關于某事的情況。如：

4. 其后可接 that 從句，從句謂語通常用 should＋v。如：

以上一句也可用不定式來改寫：
