whi|e后加什么时态,是一般现在时吗

2个回答

  • 我找了点赞最多的回答给你.你可以有个了解先.我的总结是,while的从句中动词是延续性动词,一般会使用进行时态和一般过去或现在时态.最主要的是看具体语境,如果有能力的话你可以尝试一下自己的语感.

    一、 while 用作名词时,意为“一段时间,一会儿”.例如:

    I stayed there for a short while.

    (我在那儿呆了一小会儿.)

    The postman came a short while ago.

    (邮递员刚刚来过.)

    二、 while 用作连词时,有以下几种含义:

    1.意为“当……时候,和……同时”,引导时间状语从句.例如:

    While I was watching TV,the bell rang.

    (我看电视时,铃响了.)

    Meimei watched TV while she ate her supper.

    (梅梅边吃晚饭边看电视.)

    2.意为“虽然,尽管”,引导让步状语从句.例如:

    While it was late,he went on working.

    (虽然很晚了,但他还在继续工作.)

    While he is in poor health,he works hard.

    (虽然他身体不好,但他还是努力工作.)

    3.连接两个并列句子,表示“对比”关系.例如:

    He went out for a walk,while I stayed at home.

    (他出去散步了,而我却呆在家里.)

    I like singing while she likes dancing.

    (我喜欢唱歌,而她喜欢跳舞.)

    You like sports,while I prefer music.

    (你喜欢体育,而我更喜欢音乐.)

    三、 while 引导状语从句时,应注意以下几点:

    1.while 引导的时间状语从句既可放在句首,也可放在句末;而 while 引导的让步状语从句一般放在句首,不放在句末.另外,也可以从意义上加以区分.例如:

    While he was tired,he went on working.

    (虽然他累了,但他还是继续工作.)

    ( while 引导让步状语从句)

    While he was tired,he would have a rest.

    (他累了就休息一会儿.)

    ( while 引导时间状语从句)

    2.while 引导让步状语从句时,如果从句的主语和主句的主语相同,那么从句的主语和谓语动词 be 都可以省略.例如:

    While he was ill,he went there.(= While ill,he went there.)

    (虽然他有病,但他还是去那里了.)

    3.while 和 when 都可以引导时间状语从句,但应注意:while 引导的时间状语从句中的谓语动词必须是延续性的动词;而 when 引导的时间状语从句中的谓语动词既可以是延续性动词,也可以是非延续性动词.当时间状语从句中的谓语动词是延续性动词时,while 和 when 可以互相替换.例如:

    While we were talking,the teacher came in.

    (我们正在谈话时,老师进来了.)

    The bus had left when we arrived at the bus stop.

    (当我们到达车站时,公共汽车已经开走了.)

    ( arrive 是非延续性动词,因此,此句中的 when 不能用 while 替换.)

    When / While we were having a meeting,our teacher came in.

    (我们正在开会时,老师走了进来.)

    ( have 是延续性动词,因此,句中的 when 可以用 while 替换.)

    4.while 引导的状语从句还可以表示“某个动作正在进行的同时,另一个动作也在进行之中”.例如:

    While the teacher was speaking,the students were listening.

    (老师讲课时,学生们在听.)

    While he was writing,I was reading.
