(预测……) 例句： No one can predict what will happen in 100 years. 【易错点】 名词形式为 prediction。注意拼写，直接加-ion。 (2) environment (n.) 环境 考点： environment表示自然环境时通常为不可数名词，仅指代特定类型环境时才可用作可数。 搭配： protect the environment (保护环境); living environment (居住环境) 例句： We must do something to save the environment. 【易错点】 形容词 environmental (环境的)。不要漏掉中间的 'n'。 (3) possible (adj.) 可能的 考点： 作表语或定语。 搭配： It is possible for sb. to do sth. (某人做某事是可能的); as...as possible (尽可能……) 例句： It is possible to fly to the moon in a day in the future. 【易错点】 副词 possibly；反义词 impossible。区分 probable (很可能的，语气更强)重要句型限制：probable 只能用 It is probable that + 从句，不可接 for sb. to do 补充例句：It is probable that robots will help us more in the future. (4) peace (n.) 和平 考点： 不可数名词。 搭配： in peace (平静地；和平地); world peace (世界和平) 例句： People hope for world peace. 【易错点】 形容词 peaceful (和平的；宁静的)。a peaceful village (一个宁静的村庄)。 (5) pollute (v.) 污染 考点： 及物动词。 搭配： pollute the air/water/land (污染空气/水/土地) 例句： Factories should not pollute the river. 【易错点】 名词 pollution (污染，不可数)。heavy pollution (严重污染)。 (6) robot (n.) 机器人 考点： 可数名词。 搭配： household robots (家用机器人); industrial robots (工业机器人) 例句： Robots will help us do heavy work in the future. 【易错点】 复数直接加s。注意发音重音在第一个音节。 (7) human (n./adj.) 人类；人的 考点： 作名词时常用复数 humans 表示“人类”整体；作形容词修饰名词。 搭配： human beings (人类); human nature (人性) 例句： Humans and robots will live together. 【易错点】 不要混淆 humane (人道的；仁慈的)。 2. 词性转换汇总 predict (v.) 预测 -> prediction (n.) 预测 pollute (v.) 污染 -> pollution (n.) 污染 peace (n.) 和平 -> peaceful (adj.) 和平的 possible (adj.) 可能的 -> possibly (adv.) 可能地 -> impossible (adj.) 不可能的 serve (v.) 服务 -> service (n.) 服务 danger (n.) 危险 -> dangerous (adj.) 危险的 二、重点短语清单 in the future 在未来 用法： 泛指将来，常与一般将来时连用。 对比： in future (今后，从今以后，侧重态度改变)。本单元主要用 in the future。 例句： Life will be different in the future. play a part / play a role 参与；发挥作用 用法： play a part/role in doing sth. (在做某事中发挥作用)。 例句： Everyone should play a part in saving the earth. over and over again 多次；反复地 用法： 强调动作的重复性，常含厌烦或机械意味。 例句： The robot can do the same job over and over again. fall down 倒塌；跌倒 用法： 不及物短语，无被动语态。 例句： Many old buildings fell down in the earthquake. look for 寻找 用法： 强调寻找的过程。 对比： find (找到，强调结果)。 例句： Scientists are looking for new energy sources. wake up 醒来；唤醒 用法： 可用于比喻“意识到”。 例句： We need to wake up to the environmental problems. be able to 能够 用法： 相当于 can，但有人称和时态变化 (will be able to, was able to)。 例句： Humans will be able to live on Mars one day. hundreds of 数以百计的；许多 用法： 模糊数字，前不加具体数字，后接复数名词。 对比： two hundred (两百，具体数字，不加s，不加of)。 例句： There are hundreds of stars in the sky. make sure 确保；查明 用法： make sure (that)... 或 make sure to do sth. 例句： Make sure you turn off the lights before you leave. agree with 同意（某人/某观点） 用法： agree with sb. / agree with what sb. said. 例句： I agree with you. Robots will make life easier. 三、核心语法突破 1. 一般将来时 (Simple Future Tense) 【概念】 表示将来某个时间要发生的动作或存在的状态，或对未来的预测。 【两种主要结构】 结构 用法侧重 例句 will + 动词原形 1. 临时决定 2. 客观预测（认为会发生） 3. 承诺、意愿 I think it will rain tomorrow. I will help you with your homework. be going to + 动词原形 1. 计划、打算（主观意图） 2. 有迹象表明即将发生 Look at the clouds! It is going to rain. I am going to be a teacher. 【易错警示】 There be 句型的将来时： There will be... (将有……) There is/are going to be... (将有……) 错：There will have... (绝对错误！) 时间状语： tomorrow, next week, in the future, in + 时间段 (in 10 years), soon, later等。 否定与疑问： Will you...? / Won't you...? Are you going to...? 2. 情态动词表示推测 (might / could) 【用法】 在谈论未来时，如果不确定，常用 might 或 could 代替 will，表示“可能”。 结构： Subject + might/could + verb (原形). 程度： might/could 的可能性 < will。 例句： People might live to be 200 years old. (人们可能活到200岁。) Robots could do dangerous jobs. (机器人可能会做危险的工作。) 【易错点】 might/could 后必须跟动词原形，无人称和数的变化。 错：He mights go. -> 对：He might go. 四、经典句型与写作素材 1. 询问与表达预测 Q: What do you think the future will be like? (你认为未来会是什么样？) A: I think there will be more trees and less pollution. (我认为会有更多的树和更少的污染。) Q: Will people use money in 100 years? (100年后人们还会用钱吗？) A: No, they won't. Everything will be free. (不，不会了。所有东西都将免费。) Q: Where do you think you will live? (你认为你会住在哪里？) A: I might live in a city under the sea. (我可能住在海底城市。) 2. 描述未来职业与计划 I am going to study computer science because I want to be a programmer. (我打算学习计算机科学，因为我想成为一名程序员。) Robots will help humans do heavy and dangerous work. (机器人将帮助人类做繁重和危险的工作。) It is impossible for humans to live without water. (人类没有水生存是不可能的。) 3. 写作模板：My Life in 20 Years Title: My Life in 20 Years What will my life be like in 20 years? I have made some predictions. First, I think I will be a doctor. I am going to study medicine hard at university. I believe I will work in a big hospital and help sick people. It will be a busy but meaningful job. Second, I might live in a smart apartment in Beijing. There will be robots in my home. They will cook meals and clean the floor for me. I will have more time to travel and read books. Finally, I hope the environment will be better. There will be blue skies and clean rivers. Everyone will play a part in protecting the earth. I believe my dream will come true if I work hard from now on. 五、课堂实战演练 （一）单项选择 — Do you think there ________ fewer cars in the future? — Yes, I think so. People will take the subway more.
