初中英語語法—一般將來時詳解和習(xí)題

字號:

一般將來時表示將要發(fā)生的動作或存在的狀態(tài)以及計劃、打算做某事。E.g. They will have a football match tomorrow. He will be thirty next week. She is going to buy a coat this afternoon.
     其結(jié)構(gòu)有如下幾種: 1)will + 動詞原形(will可以用于任何人稱) 需要注意的是當(dāng)主語是第一人稱時will可以換成shall,特別是在以I或we作主語的問句中,一般用shall. e.g. Shall we go to the zoo? 2)be going to +動詞原形 3)現(xiàn)在進(jìn)行時也可表示將來,前邊已經(jīng)講過,這里不在重復(fù).
     第一種結(jié)構(gòu)的句式變化是: 變否定句在will后邊加not. 變一般疑問句把will提前. e.g. She will be back in three days. She will not be back in three days. Will She be back in three days? 第二種結(jié)構(gòu)的句式變化要在be上做文章. E.g. They are going to clean their classroom. They are not going to clean their classroom. Are they going to clean their classroom?
     其時間狀語有如下幾種 1)this引導(dǎo)的短語 如 this year 2)tomorrow及其相關(guān)短語如tomorrow morning 3)next引導(dǎo)的短語 如 next month 4) from now on ; in the future ; in an hour 等。
     學(xué)生常見錯誤如下:
    一、易忽視動詞用原形形式
     例:1 He will is (be) at school next Monday.
     2 He is going to does (do) his homework after school.
     答案:1 be 2 do
     解析:第一題有的同學(xué)一看he做主語就用了is,忽視了will后應(yīng)加動詞原形。我們在寫句子時,很容易把動詞丟掉,“英語句子里,動詞不能少”的規(guī)律必須要牢記。第二題中to后加動詞原形,而不是用單三人稱.。
    二、be going to +動詞原形與will+動詞原形用法不清楚
     例:我正努力學(xué)習(xí),準(zhǔn)備參加英語考試。
     I am studying hard and I will try for my English exams.
     答案:I am studying hard and I am going to try for my English exams.
     解析:“be going to” 表示計劃、打算要做某事。E.g. He is going to visit his friends. 還表示某種跡象表明會發(fā)生某事.e.g. Look at the clouds. It’s going to rain. 而“Will+動詞原形 ”指對將來事物的預(yù)見、表示意愿、決心。E.g. I will wait for you until you come. 在單純預(yù)測未來時,二者可以互換,但在此題中只能用be going to,而不能用will。

    答案: 1 will bring 2 Are 3 won’t leave 4Shall go 5 will 6 will go
     7 will be 8 are going to do 9 will do 10 won’t take
    三、 There be結(jié)構(gòu)的一般將來時易出錯
    例:There_________ a basketball match this afternoon. (B)
    A is going to be B is going to have C are going to be D are going to have
    答案:A
    解析:There be結(jié)構(gòu)的一般將來時既要符合There be結(jié)構(gòu),又要符合一般將來時。有的同學(xué)認(rèn)為have當(dāng)“有”講,所以選了B,但There be結(jié)構(gòu)就不成立了,此句中is是be going to中的,是由后邊的單數(shù)名詞決定的.
    四、 be going to結(jié)構(gòu)中易丟掉to
    例:I’m going _______(go) school by bike tomorrow. (C)
    A to will go B to go to C go to D to go
    答案:B
    解析:由tomorrow可知是一般將來時,be going to +動詞原形,所以先確定用to go , 在B、 D當(dāng)中選,而go to school 是固定詞組,不能因為前邊有一個to而省略,這是一個易錯點,需要注意。
     另外,在時間狀語或條件狀語從句中,若主句用了將來時,從句則用一般現(xiàn)在時,前邊已經(jīng)講過,這里不在重復(fù).
