2013中考英語備考:while的各種用法(必背重點(diǎn))

字號(hào):


    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.
    郵遞員剛剛來過。
    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.

    三、while引導(dǎo)狀語從句時(shí),應(yīng)注意以下幾點(diǎn):
    1.while引導(dǎo)的時(shí)間狀語從句既可放在句首,也可放在句末;而while引導(dǎo)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。
