小學(xué)英語語法大全:As的用法
一、作副詞,意為“相同地”,“同樣地”。例如:
They don’t have as many airplanes. 他們沒有同樣多的飛機。
二、作連詞,
1. 引導(dǎo)時間狀語從句
as與when,while都是引導(dǎo)時間狀語從句的從屬連詞,含義都是"當(dāng)……的時候"。但它們有區(qū)別:
(1). when作“當(dāng)……的時候”解,可以指較短的(一點)時間,也可指一段時間。從句的動作可以與主句的動作同時發(fā)生,也可以先于主句的動作發(fā)生。例如:
John was having his dinner when I saw him. 當(dāng)我看到約翰的時候,他正在吃飯。
She can write only when the baby is asleep. 只有嬰兒睡著的時候,她才能寫作。
(2). while常表示一段較長的時間或一個過程,強調(diào)主句謂語動詞與從句謂語動詞同時發(fā)生或在從句動作過程中發(fā)生。例如:
We must strike while the iron is hot. 要趁熱打鐵。
While we were reading, the teacher came in. 我們正在讀書的時候,老師走了進來。
(3). 但屬下列情形時,只用as, 而不用when或while。
�、� 用于表示同一個人的兩種動作交替進行,指“一邊……,一邊……”。例如:
The girl dances as she sings on the stage.那個女孩在舞臺邊唱歌邊跳舞。
He looked behind from time to time as he went forward. 當(dāng)他朝前走時,不時地向后看。
�、� 表示兩個同步發(fā)展的動作或行為,譯為“隨著……”。例如:
As time went on / by, she became more and more worried. 隨著時間的流逝,她變得越來越焦慮。
As he grew older, he became more intelligent. 隨著他年齡的增長,他變得更有才智了。
�、� 表示兩個短促行為或事件幾乎同時發(fā)生。例如:
I thought of it just as you opened your mouth. 恰好在你開口時,我想到了它。
Just as the flying worm hit her face, she gave a loud cry. 恰巧在飛蟲撞到她臉上時,她大哭起來。
2. 引導(dǎo)原因狀語從句
as,because,since都可以表示因果關(guān)系,連接原因狀語從句,含義是“因為,由于”,但它們有區(qū)別:because表示的語氣最強;as一般放在句首,語氣較弱,較口語化;since常常用在書面語中,表示多為對方已知的、或稍加分析便可得知的原因,有時可譯作“既然”。例如:
I do it because I like it. 我做這件事是因為我喜歡。
Since many of the customers work during the day, Billy has to collect the money at night. 因為許多顧客白天上班,所以畢利只好晚上去收錢。
As she has been ill perhaps she'll need some help. 她由于生病可能需要些幫助。
3. 引導(dǎo)讓步狀語從句
as與although (或though),however (或no matter how)等都可以引導(dǎo)讓步狀語從句,含義是“雖然,盡管”,但它們有區(qū)別:although語氣稍正式些,可放在句首,也可放在句中,主句中不能再用 but,但可以用yet;as所表示的語氣較強,引導(dǎo)的讓步狀語從句用倒裝語序;however引導(dǎo)讓步狀語從句時,它的后面可跟形容詞或副詞,也要用倒裝語序。例如:
Although they are poor they are happy. 雖然他們很窮,但很快樂。
Angry as he was, he managed to speak calmly. 雖然他很生氣,但是他講話很平靜。
However hard the question is, he can answer it. 不管問題有多難他都能回答。
注意:當(dāng)as引導(dǎo)讓步狀語從句時,句子的倒裝語序有以下三種形式:
(1). 形容詞或副詞+as+主語+連系動詞be或?qū)嵙x動詞。例如:
Rich as he is, he never spends a cent on clothes. 雖然他很富有,但他從不花一分錢在衣服上。
Much as I admire his courage, I don’t think he acted wisely. 我雖然佩服他的勇氣,但我認(rèn)為他這樣做是不聰明的。
(2). 名詞+as+主語+連系動詞be (注意句首的名詞不帶冠詞)。例如:
Child as he is, he knows a lot. 盡管他是個孩子,但懂很多事情。
Boy as he was, he was chosen king. 盡管他還是個孩子,但卻被立為國王。
(3). 實義動詞+as+主語+助動詞[如果沒有助動詞,則要加上一個do(does或did)]。例如:
Try as he may, he never succeeds. 盡管他很努力,但總是不成功。
Change your mind as you will, you will gain no additional support. 即使你改變主意,你也不會得到另外的支持。
4. 引導(dǎo)方式狀語從句,意為“如”,“像”,“按照……的方式”。如:
I want you to tell my friend your very interesting experience exactly as you have told it to me. 我想讓你像給我講述的那樣,給我的朋友講一講你那段極其有趣的經(jīng)歷。
Remember, you must do everything as I do. 記住,你必須按照我做的那樣做一切。
注意:like在非正式語體中可以有與as相同的用法。如:
I can’t sing like I used to.我不能像以前那樣唱歌了。
He writes just like his brother did when he was young. 他現(xiàn)在寫文章正像他哥哥年輕時寫文章一樣。
5. 引導(dǎo)比較狀語從句,用于“as...as...或 not so/ as...as...”中,前一個as是副詞,后一個as是連詞,意為“如(不如)…一樣”。如:
(1). You hate her as much as I (=as I hate her).
(2). I don't speak English so/ as well as he does.
注意:句中連詞as后面的代詞實際是省略了與主句相同的部分,即例(1)可以寫成You hate her as much as I hate her. 如果很明顯就能看出所省略的部分,意義不會含糊不清時,在口語中也可以用代詞的賓格形式。例:At your age you can’t expect to play football as well as me (= as I do).但例(1)就不能改I為me,改后意思就變?yōu)椋篩ou hate her as much as you hate me. 你恨她像恨我一樣深;而原句的意思為:你恨她像我恨她一樣深。
