be going to與will的區(qū)別
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 come at you,I'll stay with you and help you will和be going to的選用原則 1.關(guān)于“打算”
原先作好的打算用“be going to”.
“Kate is in hospital.” “Yes,I know.I am going to see her this afternoon.” “凱特在住院.”“是的,我知道.我下午要去看她.” 說話時即時的打算用“will”.
“Kate is in hospital.” “Oh,really,I didn’t know.I will go and see her at once.” “凱特在住院.”“哦,是嗎?我都不知道呢.我得馬上去看她.”
2.關(guān)于“預料”
在有跡象表明的情況下的預料用“be going to” Look at the clouds.It’s going to rain.你看天上的云.快下雨了.My God!We are going to crash.天哪!我們快撞車了.
在沒有跡象表明的情況下進行的猜測用“will,be going to”皆可.I think the weather will be nice.I think the weather is going to be nice.我想天會晴朗.
Do you think the car will start?Do you think the car is going to start?你想車能發(fā)動起來嗎?
當動詞表示內(nèi)心活動時,表示猜測的句子必須用“will” I think she will like the cake I made for her.我想她會喜歡我為她做的蛋糕.
"be going to"中的be是助動詞,它有am,is,are三種形式,沒有什么實際意義；to是動詞不定式的標志詞,標志詞后動詞用原形.它們?nèi)齻€總是形影不離,在句中共同表達"計劃、打算、準備去做……"的意思.如：
I am going to sell this old car,and buy a new one.我打算賣掉這輛舊車,然后買輛新車.
用法篇
"be going to"必須與表示將來的時間信息詞如this afternoon,tomorrow,the day
after tomorrow以及next系列時間短語等連用.它可表示：1.事先經(jīng)過考慮、安排近期要做的事情.如：
They are going to the park this weekend.他們打算這周末去公園.2.根據(jù)目前某種跡象判斷某事非常有可能發(fā)生.如：
What bad weather!It is going to snow tomorrow.多糟的天氣!看來明天要下雪.另外
1."be going to"的肯定式是"主語 + be going to + do(動詞原形) + ...".上面的例句中就有肯定句,再仔細看看吧!
2."be going to"的否定式是在助動詞be后加not,即：主語 + be + not + going to + do +...如：
Peter is not going to make a model ship.彼得不打算做一個輪船模型.3."be going to"的疑問式是把助動詞be移到句首,即：Be+主語+going to do+...這和be作聯(lián)系動詞時的用法相似.如：
Are you going to mend his chair soon?Yes,I am./ No,I'm not.你打算馬上給他修椅子嗎?是的,馬上修./不,沒這個想法.
