The Power of Creative Ideas
Creative ideas create all kinds of inventions and change our world little by little. To start with, every useful creation needs useful skills and careful discussion before it can become popular. If we divide inventions into short-term and long-term types, we will find there is no one-size-fits-all way to make new things. Every great idea comes from people who never wear out their love for trying new things.
Long ago, people carried wallets with passwords and wrote down information in notebooks made of rough fibre. They had to buy expensive writing tools, which would quickly use up their money. At that time, people used bronze, stone and frozen materials for printing. Workers melted metal, shaped bronze wares and dug long tunnels to carry materials. None of these ways were cheap or suitable for common villagers. Some workers tried to pour liquid bronze into thin layers, but most of their works could not reach the ideal standard.
Later, clever inventors worked hard to speed up creation. Cai Lun spent all his time on paper making. He discussed different materials, such as jute fibre and old cloth, and did many experiments again and again. He knew he was supposed to take responsibility for finding cheap and easy materials for writing. After lots of tries, he found a complete way to make paper: cut old cloth and plant fibre into small pieces, melt them in liquid, filter the mixture into thin layers and wait for the paper to dry in the open air. This great creation led to fast cultural development all over the world, and its influence spread from Asia to Europe.
Many other great pioneers also brought useful inventions to people. Guglielmo Marconi invented the radio, which could send signals across the sea. Alexander Bell made the telephone, so people could talk with their faraway families without traveling a long way. The Wright brothers made gliders, and after many tries, they launched the first manned plane. Cameras, laptops, high-speed trains and mini sunglasses were all invented step by step. These man-made things are cheap enough for most families to afford, and convenient digital payment has completely taken the place of paper money.
Now modern workshops have advanced printers and 3D machines. If you send a digital file to the machine’s address, plastic materials will be shaped into anything you outline. Small buttons on the machine control its whole work. In case the machine breaks down, professional officers will repair and maintain it at once. Tourists can take these light inventions to malls, airports and opera houses. Some buy squirrel-shaped nut boxes as gifts, while others take cameras to record wild animals hurt by gunshot wounds.
We should recognize that every great invention comes from hard work and wisdom. It is likely that we will meet lots of difficulties when we create new things, but we should not hate the process of trying. Even if some ideas sound wild at first, we can look at images and graphs to fully adjust our plan. When we feel tired and want to fall asleep, we can recall those pioneers’ stories. They never gave up, and their inventions themselves show that creative ideas have endless power. Only if we cooperate with each other and require ourselves to keep trying bravely, can we invent more spacecraft, satellites and rockets to set foot on faraway galaxies beyond our planet in the future.
单元核心语法总说明(Unit5 核心:被动语态,九年级必考)
本单元核心语法为被动语态,分为一般现在时、一般过去时、情态动词被动、将来时被动四类;同时搭配九年级高频辅助语法:条件状语从句、定语从句、非谓语动词、倒装句、宾语从句,全部语法例句均取自文章原句,一一对应拆解考点。
(一)被动语态(单元重中之重,原文原句拆解)
1. 原句:Cameras, laptops, high-speed trains and mini sunglasses were all invented step by step. 语法拆解:一般过去时被动语态 结构:主语 + was/were + 动词过去分词 考点:描述过去被创造、被发明的事物;invent 的过去分词为 invented;复数主语搭配 were,中考语法填空高频考点。
2. 原句:If you send a digital file to the machine’s address, plastic materials will be shaped into anything you outline. 语法拆解:一般将来时被动语态 结构:主语 + will be + 过去分词 考点:主将从现条件状语从句 + 将来被动结合;表达 “某物将会被塑造成……”,写作高分句型。
3. 原句:The mixture is filtered into thin layers.(文中造纸流程隐含被动逻辑句) 语法拆解:一般现在时被动语态 结构:主语 + am/is/are + 过去分词 考点:描述机器、工艺常态化操作,科普类阅读必考句式。
拓展原句:All new materials can be used to make different products. 语法拆解:情态动词被动语态 结构:主语 + can/may/must + be + 过去分词 考点:表 “某物能够被用来……”,书面表达万能句式。
(二)条件状语从句(if 引导,中考核心)
1. 原句:If we divide inventions into short-term and long-term types, we will find there is no one-size-fits-all way to make new things. 拆解:if 引导真实条件句,遵循主将从现规则;从句一般现在时,主句一般将来时。
2. 原句:If you send a digital file to the machine’s address, plastic materials will be shaped into anything you outline. 拆解:科技场景条件状语从句,叠加将来被动语态,单元综合语法考点。
(三)定语从句(九年级阅读长难句核心)
1. 原句:Every great idea comes from people who never wear out their love for trying new things. 拆解:who 引导限制性定语从句,先行词 people(人),关系代词 who 在从句中作主语,不可省略。
2. 原句:Guglielmo Marconi invented the radio, which could send signals across the sea. 拆解:which 引导非限制性定语从句,指代前面整句名词 the radio,逗号隔开,不能用 that 替换,阅读高频难点。
3. 原句:anything you outline 拆解:省略关系代词 that 的限制性定语从句,先行词 anything 为不定代词,引导词 that 可省略。
(四)非谓语动词(语法填空第一高频)
1. 原句:notebooks made of rough fibre 拆解:过去分词 made 作后置定语,表被动 “被制作的”,等同于 notebooks which are made of rough fibre。
2. 原句:their love for trying new things 拆解:介词 for 后接动名词 trying;介词后动词必须变 doing 形式,语法填空必考点。
3. 原句:to carry materials /to make new things 拆解:不定式 to do 作目的状语,表 “用来做某事”,作文基础加分句式。
(五)宾语从句
1. 原句:we will find there is no one-size-fits-all way to make new things. 拆解:省略引导词 that 的宾语从句,放在动词 find 后,从句使用陈述语序。
2. 原句:We should recognize that every great invention comes from hard work and wisdom. 拆解:that 引导完整宾语从句,作动词 recognize 的宾语,that 无实义,可省略。
(六)倒装句(作文结尾升华高分句型)
原句:Only if we cooperate with each other and require ourselves to keep trying bravely, can we invent more spacecraft, satellites and rockets to set foot on faraway galaxies beyond our planet in the future. 拆解:Only + 条件状语从句置于句首,主句采用部分倒装,情态动词 can 提前至主语 we 前;适用于文章结尾升华主题,阅卷加分高级句式。
(七)时间 / 让步状语从句
1. 时间状语从句:When we feel tired and want to fall asleep, we can recall those pioneers’ stories. 拆解:when 引导时间状语从句,描述动作发生的时间。
2. 让步状语从句:Even if some ideas sound wild at first, we can look at images and graphs to fully adjust our plan. 拆解:even if 引导让步状语从句,意为 “即使”,表转折逻辑,完形填空高频连词辨析。
