人教版八年级上册英语 语法知识精讲与配套练习 Unit 7 When Tomorrow Comes 📌 本单元语法焦点:一般将来时(will 结构)+ 第一条件句 📖 语法知识详解 一、一般将来时(will 结构) will 用于表达未经事先考虑的将来动作、对未来的客观预测或大胆设想。will 无人称和数的变化。 句式 结构 例句 肯定句 主语 + will + 动词原形 People will live longer in the future. 否定句 主语 + won't + 动词原形 They won't go there again. 一般疑问句 Will + 主语 + 动词原形? Will you go shopping this week? 特殊疑问句 疑问词 + will + 主语 + 动词原形? How long will you stay here? There be 句型 There will be + 名词 There will be less pollution. will vs be going to: will:临时决定、客观预测、主观意愿 → I think it will rain tomorrow. be going to:有计划、有迹象 → Look at the clouds. It's going to rain. 🎯 中考考点:中考高频考点:① There will be(❌ There will have);② will 无人称变化(❌ He wills → ✅ He will);③ 否定缩写 won't = will not。 二、第一条件句(主将从现) If 引导的真实条件句,表示有可能实现的条件和结果。 主句形式 结构 例句 一般将来时 If + 一般现在时, 主语 + will + 动词原形 If it rains, we will stay home. 情态动词 If + 一般现在时, 主语 + can/may/should + 动词原形 If you finish homework, you can play. 祈使句 If + 一般现在时, 动词原形... If you feel tired, have a rest. 一般现在时(客观事实) If + 一般现在时, 主语 + 一般现在时 If you heat ice, it melts. 核心规则:主将从现! If 引导的条件状语从句中,不能用 will 表示将来,必须用一般现在时。 ❌ If it will rain tomorrow, I will stay home. ✅ If it rains tomorrow, I will stay home. 🎯 中考考点:中考高频考点:① If 从句中绝对不能用 will(除非表示意愿);② 主句可用 will/can/should/祈使句;③ unless = if...not:Unless you work hard = If you don't work hard。 ✏️ 配套练习题 一、单项选择(10题,每题1分,共10分) 1.

A (Will there be 开头的一般疑问句,简略回答只用 will:Yes, I think there will.) 3. A (unless = if...not,引导条件句,主将从现,用 hurry。) 4. C (in 20 years 是将来时间标志,用 will do 表示将来。) 5. B (if 条件句,主将从现,she 是第三人称单数用 saves。) 6. A (if 条件句,主将从现,用 are free。) 7. B (won't pass 是否定结果,unless = if...not,句意为"除非他更努力学习,否则不会通过考试"。) 8. B (There will be 表示"将有",there be 句型不能用 have/has。) 9. A (should 表示"应该",符合"想保持健康就应该规律运动"的语境。) 10. A (if 条件句,主将从现,用 doesn't rain。) 二、完形填空 16.B (there will be more people 将有更多人,there be 句型用将来时。) 17.B (population 作主语,将来时用 will be about 9 billion。) 18.B (if 条件句主将从现,主句用 there will be more pollution。) 19.A (if 条件句,主将从现,从句用 use green energy。) 20.B (主句将来时,the air will be cleaner 空气将更清洁。) 21.B (Robots will do many jobs 机器人将做许多工作。) 22.A (if 条件句,主将从现,a robot has a problem 用 has。) 23.B (主句将来时,it will fix itself 它将自我修复。) 24.B (People will live longer 人们将活得更长。) 25.A (If we work together 如果我们共同努力,引导条件句。) 三、改写句子 1. do (对 pass the exam 提问用 What will you do,询问"你会做什么"。) 2. unless; rains (unless = if...not:unless it rains = if it doesn't rain。) 3. be (对 more cars 提问用 What will there be,there be 句型。) 4. do (对 call you 提问用 What will you do,询问"你会做什么"。) 5. don't (Unless you hurry = If you don't hurry,缺少 don't。) 四、十二选十 26. A (will)考查 There be 句型的一般将来时。句意:"2050年,我们的日常生活中将会有更多的变化。"There will be + 名词,表示"将有……",是 Unit 7 的核心句型。 27. H (does)考查第一条件句(主将从现)。if 引导的条件状语从句中,主语 technology 是第三人称单数,描述当前发展趋势用一般现在时,故填 does,构成 is developing / does developing 搭配(此处 does 替代实义动词 develop 的第三人称单数,表示"确实在快速发展")。 28. F (have)考查一般将来时的谓语结构。主句主语 we 后接动词原形 have,表示"我们将拥有更智能的家居和汽车"。注意:此处 will 已用于26题,主句直接用动词原形 have 构成一般将来时的变体(口语中常用),符合"主将从现"的大框架。 29. G (do)考查情态动词/助动词表将来。Robots 作主语,后接动词原形 do,表示机器人将做大部分家务,呼应单元主题。 30. B (won't)考查一般将来时的否定。句意:"但是如果一个机器人不能正常工作,我们将不得不自己修理它。"won't = will not,后接动词原形 work,语法正确。 31. E (be)考查固定搭配。be able to 意为"能够",will 后接动词原形 be,构成 will be able to。此处 won't 已用于30题,故用 be 的原形。 32. I (rains)考查第一条件句(主将从现)。if 引导的条件状语从句,主语 it 是第三人称单数,谓语动词用 rains,主句用 will be cancelled。 33. A (will)考查一般将来时的肯定结构。主句主语 the outdoor concert 后接 will be cancelled,表示"户外音乐会将被取消"。 34. K (save)考查第一条件句(主将从现)。unless = if...not,引导条件状语从句,主语 we 是第一人称复数,谓语动词用动词原形 save, 35. B (won't)考查 There be 句型的一般将来时否定。句意:"如果我们现在不节约能源,下一代将会有更少的电力。"There won't be 表示"将不会有",won't 后接 be 动词,符合语法。 学科网(北京)股份有限公司 $
