While的用法小結
我們在英語中,經(jīng)常會運用到While,但很多學生不了解它的用法,導致使用時頻頻出錯,讓我們一起看看While的用法有哪些?下面是小編給大家?guī)淼腤hile的用法小結_While的短語搭配,以供大家參考,我們一起來看看吧!
●一、 while 用作名詞時,意為“一段時間,一會兒”。
例如:The postman came a short while ago. (郵遞員剛剛來過。)
I stayed there for a short while. (我在那兒呆了一小會兒。)
●二、 while 用作連詞時,有以下幾種含義:
1. 意為“雖然,盡管”,引導讓步狀語從句。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……時候,和……同時”,引導時間狀語從句。
例如: While I was watching TV, the bell rang. (我看電視時,鈴響了。)
Meimei watched TV while she ate her supper. (梅梅邊吃晚飯邊看電視。)
3.引導條件狀語從句 相當于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,醫(yī)生就有責任挽救。 )
4.引導原因狀語從句, 相當于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,永遠存不下錢來。 )
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. 連接兩個并列句子,表示“對比”關系。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。)
●三、 while 引導狀語從句時,應注意以下幾點:
1. while 引導的時間狀語從句既可放在句首,也可放在句末;而 while 引導的讓步狀語從句一般放在句首,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 引導讓步狀語從句)
While he was tired, he would have a rest. (他累了就休息一會兒。) ( while 引導時間狀語從句)
2. while 引導讓步狀語從句時,如果從句的主語和主句的主語相同,那么從句的主語和謂語動詞 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 都可以引導時間狀語從句,但應注意:while 引導的時間狀語從句中的
謂語動詞必須是延續(xù)性的動詞;而 when 引導的時間狀語從句中的謂語動詞既可以是延續(xù)性動詞,也可以是非延續(xù)性動詞。當時間狀語從句中的謂語動詞是延續(xù)性動詞時, 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,老師進來了。) The bus had left when we arrived at the bus stop. (當我們到達車站時,公共汽車已經(jīng)開走了。)
( arrive是非延續(xù)性動詞,因此,此句中的 when 不能用 while 替換。) When / While we were having a meeting, our teacher came in. (我們正在開會時,老師走了進來。)
( have 是延續(xù)性動詞,因此,句中的 when 可以用 while 替換。)
4. while 引導的狀語從句還可以表示“某個動作正在進行的同時,另一個動作也在進行之中”。例如:
While the teacher was speaking, the students were listening. (老師講課時,學生們在聽。)
While he was writing, I was reading.
