高考英語二輪專題語法復(fù)習(xí)學(xué)習(xí)專題講義be going to和將來完成時知識點總結(jié)

1、高中英語語法 高考復(fù)習(xí)/學(xué)習(xí)專題講義英語動詞時態(tài)be going to和將來完成時知識點總結(jié)“will / shall動詞原形”與“be going to動詞原形”兩者均可表示將來時間和意圖，有時可以換用。如：I think itll rain this evening. / I think its going to rain this evening.我想今晚會下雨。I wont tell you about it. / Im not going to tell you about it.我不會把這事告訴你的。兩者的區(qū)別是：1.若是強調(diào)某個意圖是經(jīng)過事先考慮好的，則通常要用be going

2、to；若是表示某個意圖沒有經(jīng)過事先考慮，而是在說話的當(dāng)時才臨時想到的，則通常用will。比較：Ann is in hospital.安住院了。Oh, really? I didnt know. Ill go and visit her.啊，真的嗎？我還不知道。我要去看看她。(臨時想法，不能用be going to)Ann is in hospital.安住院了。Yes, I know. Im going to visit her tomorrow.我知道，我打算明天去看看她。(事先考慮的意圖，不能用will)2.若是有跡象表明要發(fā)生某事，通常只用be going to，不用will。如：Loo

3、k at those black clouds. Its going to rain.看那些烏云，要下雨了。3.帶有時間或條件狀語從句的主句通常不宜用be going to，而用will。如：When he comes back, I will tell him the news.他回來時我就告訴他這個消息。If he comes back, I will tell him the news.他若回來我就告訴他這個消息。表將來的“be going to+動詞原形”與“現(xiàn)在進行時”1.be going to主要表示主觀想法或意圖，而現(xiàn)在進行時表示將來則主要強調(diào)已經(jīng)作出的安排。比較：Im goin

4、g to wash the car if I have time.若有時間我想洗洗車。(主觀想法)Im picking you up at 6; dont forget.我6點鐘來接你，不要忘了。(已作出的安排)2.但是當(dāng)要表示主觀無法控制的預(yù)測時，通常要用be going to，不能用現(xiàn)在進行時態(tài)。如：Its going to snow before long.不久會下雪。Things are going to get better soon.情況很快就會好起來。3.當(dāng)表示堅持要(不要)某人做某事時，兩者均可用。如：Shes taking going to take that medicin

5、e whether he likes it or not.不管她喜歡不喜歡，她都得吃那藥。Youre not wearing going to wear that skirt to school.你不可以穿那條裙子去上學(xué)。將來完成時主要用法歸納1.表示將來完成即表示到將來某個時間為止勢必會完成或預(yù)計要完成的動作。如：Maybe by then you will have changed your mind.也許到時候你已經(jīng)改變主意了?！癥oull have finished by tomorrow.” “I wish!”“你到明天就完成了?！薄暗溉绱?”I hope Ill have fin

6、ished the work by the end of the month.我希望我這個月底能完成工作。Demand for cars in the developed world will have reached saturation point within 20 years.不出20年，已發(fā)展國家的汽車需求將達到飽和。Planning so far ahead makes no senseso many things will have changed by next year.提前這么久就計劃并不明智到明年，許多事情都會發(fā)生變化。2.表示動詞的持續(xù)即表示某種狀況將一直持續(xù)到說話人所提及某一將來時間。如：We will have been married a year on June 25th到6月25日我們倆結(jié)婚就滿1年了。By this time next week, I will have worked for this company for 24 years.到下星期此刻，我已經(jīng)為該公司干了24年了。3.表示推測即表示根據(jù)某情況作出的推測。如：That will have been Roland.
