2020年中考英語時態復習系列（五）一般將來時

一般將來時表示將要發生的動作或存在的狀態以及計劃、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.
     其結構有如下幾種: 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)現在進行時也可表示將來,前邊已經講過,這里不在重復.
     第一種結構的句式變化是: 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? 第二種結構的句式變化要在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引導的短語 如 this year  2）tomorrow及其相關短語 如tomorrow morning 3）next引導的短語 如 next month  4) from now on ; in the future ; in an hour 等。
    做題時常見錯誤如下：
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：第一題有的同學一看he做主語就用了is，忽視了will后應加動詞原形。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：我正努力學習，準備參加英語考試。
     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 ”指對將來事物的預見、表示意愿、決心。e.g. i will wait for you until you come. 在單純預測未來時，二者可以互換，但在此題中只能用be going to，而不能用will。
