begoingto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(diǎn)差別：

1.begoingto表示近期、眼下就要發(fā)生的事情，will

表示的將來(lái)時(shí)間則較遠(yuǎn)一些，如：Heisgoingtowritealettertonight.Hewillwriteabookoneday.

2.begoingto表示根據(jù)主觀判斷將來(lái)絕對(duì)發(fā)生的事情，will表示客觀上將來(lái)勢(shì)必發(fā)生的事情。如：Heisseriouslyill.Heisgoingtodie.Hewillbetwentyyearsold.

3.begoingto含有“打算，準(zhǔn)備”的意思，而will則沒(méi)有這個(gè)意思，如：Sheisgoingtolendusherbook.Hewillbehereinhalfanhour.

4.在有條件從句的主句中，一般不用begoingto，而多用will。如：Ifanybeastcomesatyou,I'llstaywithyouandhelpyou.

5.will可以表示主動(dòng)為他人做某事或是給出一個(gè)承諾，可以翻譯為‘為’和‘會(huì)’。Itisverycold.Iwillmakeyousomehotcoffee.Ifyoutakepartintheelection,Iwillsupportyou.
