一般疑问句现在完成进行时介词短语介词疑问词组

考点名称:一般疑问句

  • 一般疑问句:
    是疑问句的一种。通常用yes,no来回答的疑问句叫做一般疑问句。口语中若无特殊含义,句末用升调。
    其结构是:系动词be/助动词/情态动词+主语+其他成分? 
    通常回答为:   
    肯定:Yes+主语+提问的助动词   
    否定:No+主语+提问的助动词+not 
    例如:
    Are you from Japan?   Yes, I am./No, I'm not.
    Do you live near your school? Yes, I do./No, I don't. 
    Can you speak French?  Yes, I can./No, I can't.

  • 一般疑问句的特性:
    1.将陈述句变为一般疑问句时,如句中有be 动词(am/ is/ are)时,可直接将它们提至主语前。
    如主语为第一人称,应将其改为第二人称。如:
    I'm in Class 2Grade 1. →Are you in Class 2Grade 1﹖
    We're watching TV. →Are you watching TV﹖
    2.陈述句中有情态动词(can、may、must …)时,也可直接将它们提至主语前,即可成为一般疑问句。如:
    He can swim now. →Can he swim now﹖
    The children may come with us. → May the children come with us﹖
    3.陈述句中只有一个实义动词作谓语且其时态为一般现在时,变为一般疑问句时要在句首加do或does主语后的实义动词用原形。如:
    I like these animals. →Do you like these animals﹖
    She wants to go to the movies. → Does she want to go to the movies﹖
    4.一般疑问句一般读升调(↑)
    5.一般疑问句有时不用yes或 no 回答。如:
    Are they in town now﹖
    I think so.
    May I sit here﹖
    Certainly.
    Does he like soccer﹖
    Sorry I don't know.
    6. 一般疑问句的第一单词总是虚词,读的时候要读轻声。

  • 陈述句变为一般疑问句技巧:
    根据一般疑问句不同的家族,可以用不同的方法将陈述句变为相应的一般疑问句。
    1、第一家族:含be动词或情态动词的句子
    秘诀:一调二改三问号
    一调:即把句中的be或情态动词调到主语前;
    二改:改换主语称谓,即将句中的主语I\my \mines\we\our\ours等。第一人称分别改为相应的第二人称you\your\ yours等;
    三问号:句末的句号改为问号。如:
    Eg. I am an English teacher.    →    Are you an English teacher?
    Eg. We can speak English fluently.   →    Can you speak English fluently?

    2、第二家族:含行为动词(或称为实义动词)的句子
    秘诀:一加二改三问号
    一加:即在句首加助动词Do或Does;
    二改:1、把谓语动词改为原形;2、改换主语称谓(同第一家组);
    三问号:句末的句号改为问号。
    Eg. We read English every morning. → Do you read English every morning?
    Eg. Tom’s father listens to English on the radio every evening. →Does Tom’s father listen to English on the radio every evening?
    特别注意:对于第二家族一定要注意动词的还原,因为时态与数的变化已经体现在助动词上了。

    3、加强记忆口诀:
    肯变一,并不难,can 或be提在前;
    谓语若为行为动,do 或does句首用。

考点名称:现在完成进行时

  • 现在完成进行时:
    是英语中,动词的一种基本时态,其构成为:主语+have/has+been+现在分词+其他成分。
    基本结构:
    I/we/theyhavebeen+动词的现在分词
    He/she/ithasbeen+动词的现在分词
    在当代英语中,现在完成进行时有时也可用否定结构。如:
    Since that unfortunate accident last week, I haven’t been sleeping at all well.
    自从上周发生了那次不幸事故之后,我一直睡得很不好.
    He hasn’t been working for me and I haven’t had that much contact with him.
    他并没有给我工作过,我和他没有过那许多接触。
    否定句构成:
    主语+has/have+not+been+现在分词+其他
    一般疑问句构成:
    Have/has+主语+been+现在分词+其他

  • 现在完成进行时主要用法:
    (一)表示从过去某时开始一直持续到现在的动作,并且还将持续下去。
    The Chinese have been making paper for two thousand years.

    (动作还将继续下去)
    I have been learning English since three years ago.
    自从三年前以来我一直在学英语。

    (二)表示在说话时刻之前到现在正在进行的动作。
    We have been waiting for you for half an hour.
    我们已经等你半个钟头了
    (人还没到,如同在电话里说的,还会继续等)

    (三)有些现在完成进行时的句子等同于现在完成时的句子。
    They have been living in this city for ten years.
    They have lived in this city for ten years.
    他们在这个城市已经住了10年了。
    I have been working here for five years.
