英語語法大全：一般將來時(shí)

　　【導(dǎo)語】英語語法讓很多學(xué)生都頭疼，因?yàn)閺?fù)雜難懂的句式和詞組有時(shí)難以記憶。英語網(wǎng)為大家整理了小學(xué)英語語法大全，希望對(duì)同學(xué)們的英語語法學(xué)習(xí)有所幫助。更多內(nèi)容盡在英語網(wǎng)。

　　一般將來時(shí)將來做某事

　　A、構(gòu)成形式：

　　(1)主語+be going to+動(dòng)詞原形+其他。

　　(2)主語+will+動(dòng)詞原形+其他。

　　B、判斷依據(jù)：

　　一個(gè)句子中既有be動(dòng)詞，又有g(shù)oing、to和動(dòng)詞，且動(dòng)詞用的是原形，句中往往有tomorrow、soon、next week等詞。

　　C、句型變換：

　　She is going to have a picnic tomorrow.

　　She isnt going to have a picnic tomorrow.

　　Is she going to have a picnic tomorrow?

　　Yes, she is. / No, she isnt.

　　They are going to visit their grandparents next Sunday.

　　They arent going to visit their grandparents next Sunday.

　　Are they going to visit their grand parents next Sunday?

　　Yes, they are. / No, they arent.

　　三組將來時(shí)間表示法的用法比較

　　一、 will / shall+動(dòng)詞原形與be going to+動(dòng)詞原形

　　兩者均可表示將來時(shí)間和意圖，有時(shí)可以換用。如：I think itll rain this evening. / I think its going to rain this evening. 我想今晚會(huì)下雨。I wont tell you about it. / Im not going to tell you about it. 我不會(huì)把這事告訴你的。兩者的區(qū)別是：1. 若是強(qiáng)調(diào)某個(gè)意圖是經(jīng)過事先考慮好的，則通常要用be going to;若是表示某個(gè)意圖沒有經(jīng)過事先考慮，而是在說話的當(dāng)時(shí)才臨時(shí)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(shí)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：Look at those black clouds. Its going to rain. 看那些烏云，要下雨了。3. 帶有時(shí)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(shí)我就告訴他這個(gè)消息。If he comes back, I will tell him the news. 他若回來我就告訴他這個(gè)消息。

　　二、be going to+動(dòng)詞原形與現(xiàn)在進(jìn)行時(shí)

　　1. be going to主要表示主觀想法或意圖，而現(xiàn)在進(jìn)行時(shí)表示將來則主要強(qiáng)調(diào)已經(jīng)作出的安排。比較：Im going to wash the car if I have time. 若有時(shí)間我想洗洗車。(主觀想法)Im picking you up at 6; dont forget. 我6點(diǎn)鐘來接你，不要忘了。6(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(shí)，通常要用be going to，不能用現(xiàn)在進(jìn)行時(shí)態(tài)。如：Its going to snow before long. 不久會(huì)下雪。Things are going to get better soon. 情況很快就會(huì)好起來。3. 當(dāng)表示堅(jiān)持要(不要)某人做某事時(shí)，兩者均可用。如：Shes taking [going to take] that medicine 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)。

　　三、be going to+動(dòng)詞原形與be to+動(dòng)詞原形

　　be to+兩者均可表示按計(jì)劃或安排要發(fā)生的動(dòng)作，有時(shí)可互換(但be to比be going to正式)。如：Where are we going to stay tonight? 我們今晚住哪里?Im (going) to play tennis this afternoon. 我打算今天下午打網(wǎng)球。另外，be going to 還可表示預(yù)測，即根據(jù)已有跡象預(yù)測將要發(fā)生的動(dòng)作，此時(shí)不能用be to。如：Look, its going to rain. 看，要下雨了。
