be going to be和will be的用法

1个回答

  • e going to与will两者都可表示将要发生的事、将要去做某事,但它们有如下几点区别:

    1.be going to 表示近期、眼下就要发生的事情,will 表示的将来时间则较远一些,如:

    He is going to write a letter tonight.

    He will write a book one day.

    2.be going to 表示根据主观判断将来肯定发生的事情,will表示客观上将来势必发生的事情.

    He is seriously ill.He is going to die.

    He will be twenty years old.

    3.be going to 含有“计划,准备”的意思,而 will 则没有这个意思,如:

    She is going to lend us her book.

    He will be here in half an hour.

    4.在有条件从句的主句中,一般不用 be going to,而多用will,如:

    If any beasts comes at you,I'll stay with you and help you.

    5.若表示没有经过事先计划或考虑,而是在说话的当时临时想到的意图或临时作出的决定时,则要用will.若表示经过事先考虑好的意图时,要用be going to.如:

    I’ll answer the telephone.(事先没经过考虑)

    I’m going to meet him at the railway station.(已经过考虑)

    6.在正式的通知(如新闻媒体公布的官方消息,气象预报等)中用will结构.如:

    Ji’an will be cloudy with the temperature from eighteen to twenty-eight.

    7.表示有迹象表明要发生某事,只用be going to,不用will.如:

    Look at the clouds,it’s going to be another storm.
