while用法
一、while用作名詞時(shí),意為“一段時(shí)間,一會(huì)兒”。例如:
I stayed there for a short while.
我在那兒呆了一小會(huì)兒。
The postman came a short while ago.
郵遞員剛剛來(lái)過(guò)。
二、while用作連詞時(shí),有以下幾種含義:
1.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。
2.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。
3.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。
