be going to與will兩者都可表示將要發(fā)生的事、將要去做某事,但它們有如下幾點區(qū)別：
1.be going to 表示近期、眼下就要發(fā)生的事情,will 表示的將來時間則較遠(yuǎn)一些,如：
He is going to write a letter tonight.
He will write a book one day.
2.be going to 表示根據(jù)主觀判斷將來肯定發(fā)生的事情,will表示客觀上將來勢必發(fā)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“計劃,準(zhǔn)備”的意思,而 will 則沒有這個意思,如：
She is going to lend us her book.
He will be here in half an hour.
4.在有條件從句的主句中,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.
在下列情況下用will:
1.根據(jù)說話者的見解和觀點對未來作出預(yù)言時
