Unit 5 语法(一般将来时)讲解与练习-2026-2027学年沪教版英语七年级上册

Unit5 Off to space语法讲解与练习 一般将来时（will / be going to）精讲 一、两种核心句型总览（单元必考） 两种结构：will + 动词原形；be going to +动词原形 （一）will 句型（通用将来时） 核心规则：所有人称通用，后面永远接动词原形，无人称、单复数变化 1. 完整句式结构 ✅ 肯定句：主语 + will + 动词原形 + 其他 ❌ 否定句：主语 + won’t (will not) + 动词原形 + 其他 ❓ 一般疑问句：Will + 主语 + 动词原形 + 其他？ 👉 简答：Yes, 主语 + will. / No, 主语 + won’t. 2.单元原话题例句（太空主题） - We will visit the space museum next Sunday. 我们下周日将参观太空博物馆。 - They will not / won’t fly to space tomorrow. 他们明天不会飞往太空。 - Will astronauts live on Mars one day? 有一天宇航员会住在火星上吗？ 3. will 专属用法 ① 临时决定、当场做出的选择（无提前计划） ② 单纯对未来的预测、客观事实 ③ 表示意愿、承诺、许诺 （二）be going to 句型（计划/迹象将来时） 核心规则：be 动词随主语变化（am / is / are），后接动词原形 I → am ；单数/不可数 → is ；复数/you → are 1. 完整句式结构 ✅ 肯定句：主语 + am/is/are + going to + 动词原形 + 其他 ❌ 否定句：主语 + am/is/are + not + going to + 动词原形 + 其他 ❓ 一般疑问句：Am/Is/Are + 主语 + going to + 动词原形 + 其他？ 👉 简答：Yes, 主语 + be. / No, 主语 + be not. 2.单元话题例句 - I am going to learn more about space. 我打算学习更多太空知识。 - She isn’t going to watch the space show. 她不打算看太空展览。 - Are you going to take a space trip? 你打算进行一次太空旅行吗？ 3. be going to 专属用法（考试高频） ① 提前计划、打算好的事情（早已安排） ② 有迹象、有征兆即将发生的事（看天气、状态判断） 例：Look at the dark clouds. It is going to rain. 看乌云，马上要下雨了。 2、 重难点：will vs be going to 精准区别 一句话总结:will 侧重无依据的主观预测、临时决定、承诺；be going to 侧重有计划、有客观迹象的将来 维度 be going to will 核心含义 计划、打算、有迹象 临时决定、客观预测、承诺 时间特点 事先想好、提前安排 当场决定、无提前计划 人称变化 随主语变 am/is/are 所有人称统一用 will 单元场景 我打算学习太空知识、计划参观航天馆 未来人类会登陆火星、我会帮你讲解知识点 三、一般将来时标志词 tomorrow（明天）、next week / next Sunday（下周/下周日）、soon（不久）、one day（将来某天）、in the future（在未来）、this afternoon（今天下午） 四、单元必考易错点 1. ❌ 错误：will + doing / to do ✅ 正确：will 后只能接动词原形 2. ❌ 错误：be going to + doing ✅ 正确：be going to 后只能接动词原形 3. am not 无缩写，is not=isn’t，are not=aren’t 4. will 否定统一为 won’t，没有 willn’t 写法 5. 有迹象用 be going to，临时决定/客观预测用 will 【巩固练习】 一、用所给词的正确形式填空 1.
