    The present continuous tense 现在进行时态

     

    We can use the present continuous tense to refer to things that are happening now. Read the forms of the tense.现在进行时态指事情正在发生。看一下这个时态的构成:

    We are destroying our best fighters against pollution.我们正在毁灭这些反污染的斗士。

    1. 用法

    现在进行时时表示正在进行的动作,通常由be动词+动词现在分词形式构成,可与now,at present, at this moment, these days等时间状语连用,也可不用时间状语。例如:

    ---What are you doing?       ---I am reading.

    He is not working.

    Are they planting trees?

    2. 现在分词构成:

    现在分词由词尾-ing构成,例如:

    do---doing 词尾+ing

    write---writing 结尾有不发音“e”, 去“e”+ing

    put---putting 重读闭音节,结尾只有一个辅音,双写这一辅音+ing

    die-dying 结尾为ie,变ie为y+ing

    3.Things to remember 要记住的知识

    I am

    I'm

    He/She/It is

    He's/She's/It's

    We/They/You are

    We're/They're/You're

    What is

    What's

     

    4.We do not often use the verbs below in the present continous tense.Instead,we use them in the simple present tense.下面的动词不用于现在进行时态中,因为他们表示状态和感觉,不能表示正在进行的动作,因而多用于一般现在时态中。

    hear,smell,see,taste,hate, think(=believe), mean,know,understand,believe,like,love,belong,contain

    √  (Right)

      (Wrong)

    I know the answer.

    I am knowing the answer.

    Do you like milk?

    Are you liking milk?

    They do not understand you.

    They are understanding you.

    This book belongs to May.

    This book is belonging to May.

    5.现在进行时的其他用法:(了解)

    1)现在进行时表示将来动作。

    现在进行时常可用来表示将来的动作,特别是在口语中,这时常有一个表示未来时间的状语,多指已计划安排好的事。例如:

    I'm meeting Peter tonight. He's taking me to theatre.今晚我要和彼得见面,他将带我去看戏。

    She's flying to Hong Kong tomorrow.她明天飞香港。

    2)be going to 结构可表示:

    a.准备或打算做某事。例如:

    He's going to buy a new car.她准备买一辆新车。

    He's going to be a dentist when he grows up.他长大了打算当牙医。

    b.即将发生的事或要发生的事。例如:

    It's going to be warm tomorrow.明天天气会很暖和。

    There's going to be a thunderstorm.雷雨即将来临。
