While的用法小結(jié)
我們?cè)谟⒄Z(yǔ)中,經(jīng)常會(huì)運(yùn)用到While,但很多學(xué)生不了解它的用法,導(dǎo)致使用時(shí)頻頻出錯(cuò),讓我們一起看看While的用法有哪些?下面是小編給大家?guī)?lái)的While的用法小結(jié)_While的短語(yǔ)搭配,以供大家參考,我們一起來(lái)看看吧!
●一、 while 用作名詞時(shí),意為“一段時(shí)間,一會(huì)兒”。
例如:The postman came a short while ago. (郵遞員剛剛來(lái)過(guò)。)
I stayed there for a short while. (我在那兒呆了一小會(huì)兒。)
●二、 while 用作連詞時(shí),有以下幾種含義:
1. 意為“雖然,盡管”,引導(dǎo)讓步狀語(yǔ)從句。例如:
While it was late, he went on working. (雖然很晚了,但他還在繼續(xù)工作。)
While he is in poor health, he works hard. (雖然他身體不好,但他還是努力工作。)
2. 意為“當(dāng)……時(shí)候,和……同時(shí)”,引導(dǎo)時(shí)間狀語(yǔ)從句。
例如: While I was watching TV, the bell rang. (我看電視時(shí),鈴響了。)
Meimei watched TV while she ate her supper. (梅梅邊吃晚飯邊看電視。)
3.引導(dǎo)條件狀語(yǔ)從句 相當(dāng)于as long as,譯作“只要”。例如: While there is life, there is hope. (有生命,就有希望。)
While a spark of life remains, it is a doctor's duty to save the patient. (只要病人還有一息生機(jī),醫(yī)生就有責(zé)任挽救。 )
4.引導(dǎo)原因狀語(yǔ)從句, 相當(dāng)于since, 有“既然”的意思。例如:
You'll never save any money while you're so extravagant. (你這么奢侈,永遠(yuǎn)存不下錢(qián)來(lái)。 )
I'd like to get it settled today while we're at it. (既然我們著手干了,我想今天就把它干完。 )
5. 連接兩個(gè)并列句子,表示“對(duì)比”關(guān)系。例如:
He went out for a walk, while I stayed at home. (他出去散步了,而我卻呆在家里。) I like singing while she likes dancing. (我喜歡唱歌,而她喜歡跳舞。) You like sports, while I prefer music. (你喜歡體育,而我更喜歡音樂(lè)。)
●三、 while 引導(dǎo)狀語(yǔ)從句時(shí),應(yīng)注意以下幾點(diǎn):
1. while 引導(dǎo)的時(shí)間狀語(yǔ)從句既可放在句首,也可放在句末;而 while 引導(dǎo)的讓步狀語(yǔ)從句一般放在句首,不放在句末。另外,也可以從意義上加以區(qū)分。例如:
While he was tired, he went on working. (雖然他累了,但他還是繼續(xù)工作。) ( while 引導(dǎo)讓步狀語(yǔ)從句)
While he was tired, he would have a rest. (他累了就休息一會(huì)兒。) ( while 引導(dǎo)時(shí)間狀語(yǔ)從句)
2. while 引導(dǎo)讓步狀語(yǔ)從句時(shí),如果從句的主語(yǔ)和主句的主語(yǔ)相同,那么從句的主語(yǔ)和謂語(yǔ)動(dòng)詞 be 都可以省略。例如:
While he was ill, he went there. (= While ill,he went there.) (雖然他有病,但他還是去那里了。)
3. while 和 when 都可以引導(dǎo)時(shí)間狀語(yǔ)從句,但應(yīng)注意:while 引導(dǎo)的時(shí)間狀語(yǔ)從句中的
謂語(yǔ)動(dòng)詞必須是延續(xù)性的動(dòng)詞;而 when 引導(dǎo)的時(shí)間狀語(yǔ)從句中的謂語(yǔ)動(dòng)詞既可以是延續(xù)性動(dòng)詞,也可以是非延續(xù)性動(dòng)詞。當(dāng)時(shí)間狀語(yǔ)從句中的謂語(yǔ)動(dòng)詞是延續(xù)性動(dòng)詞時(shí), while 和 when 可以互相替換。例如:
While we were talking, the teacher came in. (我們正在談話時(shí),老師進(jìn)來(lái)了。) The bus had left when we arrived at the bus stop. (當(dāng)我們到達(dá)車(chē)站時(shí),公共汽車(chē)已經(jīng)開(kāi)走了。)
( arrive是非延續(xù)性動(dòng)詞,因此,此句中的 when 不能用 while 替換。) When / While we were having a meeting, our teacher came in. (我們正在開(kāi)會(huì)時(shí),老師走了進(jìn)來(lái)。)
( have 是延續(xù)性動(dòng)詞,因此,句中的 when 可以用 while 替換。)
4. while 引導(dǎo)的狀語(yǔ)從句還可以表示“某個(gè)動(dòng)作正在進(jìn)行的同時(shí),另一個(gè)動(dòng)作也在進(jìn)行之中”。例如:
While the teacher was speaking, the students were listening. (老師講課時(shí),學(xué)生們?cè)诼?tīng)。)
While he was writing, I was reading.
