五年级英语:一般将来时——be going to 与 will 的区别
一、本课知识点
五年级下册 Unit 4—Unit 6 反复出现"打算做某事""将要发生某事",这就是一般将来时。它有两种写法:be going to 和 will。这一讲把两种写法讲透,并说清什么时候用哪一个。
-
基本结构 (1) be going to + 动词原形 主语 + am/is/are + going to + do I am going to visit my grandma this weekend. She is going to buy a new bike. They are going to play football after school. (2) will + 动词原形 主语 + will + do(will 不随人称变化) I will help you. / He will come back tomorrow. 否定:will not = won't;be going to 的否定是在 be 后加 not:isn't going to。
-
什么时候用 be going to (1)事先已经打算、计划好的事: I'm going to see a film tonight.(票都买好了) (2)有迹象表明马上要发生的事: Look at the black clouds! It's going to rain.(乌云是迹象)
-
什么时候用 will (1)临时决定,说话时才想到的: —The phone is ringing. —I'll answer it.(谁去接电话,是当场决定的) (2)对将来的一种预测、承诺或祝愿: I think it will be sunny tomorrow. I will always be your friend. (3)不受个人计划影响的客观未来:The year 2050 will be different.

时间标志词(看到就用将来时) tomorrow, tomorrow morning next week / next month / next year / next Sunday this evening, this weekend in 2030, in two days(两天后) soon, later, from now on
-
三种句式的变化(以 be going to 为例) 肯定:She is going to draw a picture. 否定:She isn't going to draw a picture. 一般疑问:Is she going to draw a picture? — Yes, she is. / No, she isn't. 特殊疑问:What is she going to draw? will 的疑问句把 will 提前:Will you go with me? — Yes, I will.

二、句型操练与例题
例题1 用所给动词的适当形式填空。 1. Look! The boy _ (fall) off the bike.(答案:is going to fall,有迹象) 2. —I'm thirsty. —I _ (get) you some water.(答案:will get,临时决定) 3. We _ (visit) the science museum next Friday.(答案:are going to visit,计划) 4. It _ (be) cold tomorrow.(答案:will be,预测)
例题2 按要求改写句子。 1. They are going to clean the classroom.(改为否定句) They aren't going to clean the classroom. 2. He will come to the party.(改为一般疑问句) Will he come to the party? 3. I'm going to buy a storybook.(对画线部分 buy a storybook 提问) What are you going to do?
例题3 连词成句。 1. going, are, to, what, do, you, weekend, this (?) 参考答案:What are you going to do this weekend? 2. will, my, I, help, mother, the, with, housework (.) 参考答案:I will help my mother with the housework.
例题4 情景对话补全。 A: What are you going to do on Sunday? B: ____ (提示:我要去公园放风筝) 参考答案:I'm going to fly a kite in the park. A: That sounds great. Will it be windy? B: ______ (提示:我想会,天气预报说会刮风) 参考答案:I think it will. The weather report says it will be windy.
三、易错点提醒
- to 后忘了动词原形。写成 going to plays 或 going to playing 都是错的。
- be 动词漏掉。He going to swim 少了 is。
- will 后面加 to,写成 will to go。
- 主谓不一致。They is going to... 应为 They are going to...
- "I will" 缩写成 I'll 时忘了撇号位置。
- 回答 Will you...? 用 Yes, I will. 不要回答 Yes, I am.
- 混淆 be going to 与现在进行时:I'm going to the park(正在去)和 I'm going to go to the park(打算去),前者是进行时表位置移动,后者才是将来时。
四、分层练习
基础题 选择填空 1. There _ a sports meeting next week. A. is going to have B. will be C. will have (答案:B) 2. —Where are you going this summer? —I _ Beijing. A. am going to visit B. visit C. visited (答案:A) 3. It's 7:50. We ____ be late for school. A. are going to B. are C. were (答案:A)
提高题 用所给词的适当形式填空 4. My father _ (buy) a new car next month. 5. _ you _ (play) basketball with me tomorrow? 6. Look at the sky! It _ (rain) soon.
拓展题 小练笔(6句左右) 7. 写一写你这个周末的计划,用上 be going to 和 will 各至少一次,并给出理由。 参考范文: The weekend is coming. I'm going to visit my grandparents on Saturday morning. We are going to have lunch together. In the afternoon, I will go to the library with my friend. I think we will have a good time. On Sunday, I'm going to finish my homework first. Then I will help my mum do the housework. It's going to be a busy but happy weekend.
五、小结
记住一句话:已经计划好的用 be going to,临时决定或预测的用 will。做题时先找时间标志词(next、tomorrow、this weekend),再想主语和 be 动词的搭配,最后检查 to 后面是不是动词原形。每天用将来时写三句自己的计划,一周后这个时态就变成你的"顺手句式"了。
