(教材原句)Today, Saihanba is known as “the green miracle”. 句中的was opened和is known是由“be+过去分词”构成的被动语态结构，其中be动词跟随时态进行变化。 如：The glass was broken by a boy. 玻璃被一个小男孩打碎了。 All local roads are cleaned twice a week. 当地所有道路都会每周清扫两次。 [随学随练] 单项填空 (1) Fresh vegetables ________ every day at the market and they are quite popular.

A．produced B．produced C．was produced D．is produced 2. 定语从句 (教材原句)Many changes have taken place in the town over the last few years, and the people who live here have become rich. (教材原句)A digital product is something you sell online and doesn't have a physical form. (教材原句)The way I study is also different. 第一句中的who live here have become rich是定语从句修饰前面的people，引导词who在定语从句中作主语，不可以省略。 第二句中you sell online修饰前面的something，这个定语从句由that引导，引导词在定语从句中充当宾语，可以省略。 第三句中I study修饰前面的the way。当先行词是 the way，表示 “… 的方式”，且关系词在从句中作方式状语时，关系词可以是in which或that，也可以省略。 如：Safe cycling is important for every student who goes to school by bike. 对于每个骑自行车上学的学生来 说，安全骑行至关重要。   You can sing any English song you like in the competition.在比赛中，你可以演唱任何你喜欢的英文歌 曲。 I like the way (that /in which) he talks with villagers. 我喜欢他和村民交谈的方式。 [随学随练] 单项填空 (1) —This is the most interesting book ________ I’ve read this year. —Really? Then I’ll also read it. A．that B．which C．what D．whom (2) Music style is a way ________ music was created or played.

(教材原句)... my life is different from when I was in primary school. (教材原句)I am glad that I get to see her every day. how different countries can work...跟在动词shows后作宾语，是一个宾语从句。 when I was in primary school跟在介词后作宾语，也是一个宾语从句。 that I get to see her every day跟在形容词glad后，也是一个宾语从句。常见的表示情绪类的形容词glad，happy，sorry，amazed等后常跟that引导的宾语从句。 如：She is quite different from how she was three years ago. 她和三年前的样子差别很大。 I am surprised that we have made so much progress. 我很惊讶我们取得了这么大的进步。 [随学随练] 单项填空 (1) The kid is curious about ________ his gift looks. A．how B．what C．why D．where (2) —Do you know ________ red stands for good luck in China? —Sure. A．how B．where C．that D．what 4、 其他知识解析 1. 过去分词作定语 (教材原句)Before then, the only transport links ... were rough roads and an old railway line built in 1901. (教材原句)the feeling of love and happiness shared by my family. 第一句中built in 1901和第二句中shared by my family都是过去分词短语作后置定语。 过去分词作定语时，与被修饰的名词前构成被动关系。 如：a flat built last year 去年建的公寓 the rules discussed in the class 在课堂上讨论的规则 [随学随练] 单项填空 A new friend ________ Joe will be our classmate next term. A．calling B．called C．to call D．call 2. “make+复合宾语”结构 (教材原句)The railway has also made the transport of food easier. (教材原句)The bridge made it convenient for the villagers to travel across the river to the city. make后常跟复合宾语结构。当宾语较长时，常用it作形式宾语，而将真正的宾语不定式结构至于末尾，形成“make it+宾补+to do”结构。 如：The new road made our life better. 新路让我们的生活变好了。 The port makes it possible for villagers to sell goods far away.这座港口让村民把货物卖到远方成为可 能。 [随学随练] 单项填空 —Look! A ________ robot! —Yes, it often helps Mom ________ housework. A．cleaning, doing B．cleaning, do C．clean, with 3. 现在分词作定语 (教材原句)Our farm has a lot of laying eggs. (教材原句)Over the next 60 years, workers planted bushes and trees, creating the world's biggest man-made forest. laying和creating都是现在分词形式。前者用作定语修饰eggs；后者用作结果状语。 现在分词作定语时，通常表示主动关系或用于表用途，特征等。 现在分词作状语时，与其逻辑主语(动词的实际发出者)构成主动关系。 如：swimming pool 游泳池 The manager talking with villagers is very kind. 正在和村民交谈的经理十分和善。 He sat there, discussing business with the manager. 他坐在那儿，和经理商谈生意。 [随学随练] 单项填空 The old man walks slowly to his home, ________ a large bag on his back. A．carries B．carrying C．carry D．to carry 4. it作形式主语 (教材原句)It's amazing how much we have achieved together. 本句中it用作形式主语，真正的主语是后面的主语从句。 如：It is surprising how much benefit locals have got. 当地人收获的巨大益处令人吃惊。 [随学随练] 单项填空 —How did you feel about his success? —________ that he finished the difficult project all by himself. A．It amazed B．He was amazing C．It was amazing D．He was amazed 5、 知识过关练习 1. 词汇填空  根据据提示填写正确形式的单词，每空一词。 (1) The Internet makes it ________ (方便的) for us to communicate with each other.

(教材原句)Today, Saihanba is known as “the green miracle”. 句中的was opened和is known是由“be+过去分词”构成的被动语态结构，其中be动词跟随时态进行变化。 如：The glass was broken by a boy. 玻璃被一个小男孩打碎了。 All local roads are cleaned twice a week. 当地所有道路都会每周清扫两次。 [随学随练] 单项填空 (1) Fresh vegetables ________ every day at the market and they are quite popular. A．provide B．will provide C．are provided D．will be provided 【答案】C 【详解】句意：新鲜蔬菜每天在市场上被提供，它们很受欢迎。 provide提供；will provide将会提供；are provided被提供；will be provided将要被提供。主语“Fresh vegetables”与动词“provide”之间是被动关系，结合时间状语“every day”可知，应用一般现在时的被动语态，结构为“am/is/are+过去分词”。应填are provided。 (2) —Why have I never seen this kind of mobile phone? —Because it ________ by Huawei last month. A．produced B．produced C．was produced D．is produced 【答案】C 【详解】句意：——为什么我从没见过这种手机？——因为它是上个月由华为生产的。 根据时间状语“last month”可知，句子时态为一般过去时；主语it指代手机，与动词produce之间是被动关系，且由by引出动作执行者，故用被动语态，结构为was/were + 过去分词。主语it为单数，be动词用was，应填was produced。 2. 定语从句 (教材原句)Many changes have taken place in the town over the last few years, and the people who live here have become rich. (教材原句)A digital product is something you sell online and doesn't have a physical form. (教材原句)The way I study is also different. 第一句中的who live here have become rich是定语从句修饰前面的people，引导词who在定语从句中作主语，不可以省略。 第二句中you sell online修饰前面的something，这个定语从句由that引导，引导词在定语从句中充当宾语，可以省略。 第三句中I study修饰前面的the way。当先行词是 the way，表示 “… 的方式”，且关系词在从句中作方式状语时，关系词可以是in which或that，也可以省略。 如：Safe cycling is important for every student who goes to school by bike. 对于每个骑自行车上学的学生来 说，安全骑行至关重要。   You can sing any English song you like in the competition.在比赛中，你可以演唱任何你喜欢的英文歌 曲。 I like the way (that /in which) he talks with villagers. 我喜欢他和村民交谈的方式。 [随学随练] 单项填空 (1) —This is the most interesting book ________ I’ve read this year. —Really? Then I’ll also read it. A．that B．which C．what D．whom 【答案】A 【详解】句意：——这是我今年读过的最有趣的书。——真的吗？那我也读一读。   that（指人或物，在定语从句中作主语或宾语）；which（指物，在定语从句中作主语或宾语）；what（什么，不用于定语从句，引导名词性从句）；whom（指人，在定语从句中作宾语）。先行词“book”指物，且前面有形容词最高级“the most interesting”修饰，关系代词只能用that，不能用which。故选用that。 (2) Music style is a way ________ music was created or played. A．which B．in which C．of which D．what 【答案】B 【详解】句意：音乐风格是音乐被创作或演奏的方式。 先行词是“way”，表示“方式” 时，在从句中作方式状语，介词搭配用in，介词提前到关系代词which前，因此用in which。 3. 让步状语从句 (教材原句)Although China and Kenya are far away from each other, the railway shows... although,though,even if/though等常用于引导让步状语从句。 [随学随练] 翻译句子 尽管绘画需要时间，但它教会我们关注身边的美。 Although painting takes time, it teaches us to notice the beauty around us. 4. 宾语从句 (教材原句)... the railway shows how different countries can work together to build a better world. (教材原句)... my life is different from when I was in primary school. (教材原句)I am glad that I get to see her every day. how different countries can work...跟在动词shows后作宾语，是一个宾语从句。 when I was in primary school跟在介词后作宾语，也是一个宾语从句。 that I get to see her every day跟在形容词glad后，也是一个宾语从句。常见的表示情绪类的形容词glad，happy，sorry，amazed等后常跟that引导的宾语从句。 如：She is quite different from how she was three years ago. 她和三年前的样子差别很大。 I am surprised that we have made so much progress. 我很惊讶我们取得了这么大的进步。 [随学随练] 单项填空 (1) The kid is curious about ________ his gift looks. A．how B．what C．why D．where 【答案】A 【详解】句意：孩子很好奇他的礼物看起来怎么样。 考查宾语从句。how怎么样；what什么；why为什么；where哪里。根据“The kid is curious about …his gift looks.”可知，此处是指礼物看起来怎么样，应用how引导宾语从句；而what需要与短语“look like”搭配。故选A。 (2) —Do you know ________ red stands for good luck in China? —Sure. A．how B．where C．that D．what 【答案】C 【详解】句意：——你知道在中国红色代表好运吗？——当然。 考查宾语从句。how如何；where在哪里；that那，可引导陈述语气的宾语从句；what什么。根据“Do you know...red stands for good luck in China”可知，设空处引导宾语从句，且从句为一个成分完整的陈述句，因此此处用that引导宾语从句。故选C。 4、 其他知识解析 1. 过去分词作定语 (教材原句)Before then, the only transport links ... were rough roads and an old railway line built in 1901. (教材原句)the feeling of love and happiness shared by my family. 第一句中built in 1901和第二句中shared by my family都是过去分词短语作后置定语。 过去分词作定语时，与被修饰的名词前构成被动关系。 如：a flat built last year 去年建的公寓 the rules discussed in the class 在课堂上讨论的规则 [随学随练] 单项填空 A new friend ________ Joe will be our classmate next term. A．calling B．called C．to call D．call 【答案】B 【详解】句意：一位叫乔的新朋友在下学期将会成为我们的同学。 考查过去分词。calling叫，现在分词；called过去分词；to call动词不定式；call动词原形。根据“A new friend...Joe will be our classmate next term.”可知，空处应为非谓语动词，且与主语为被动关系，故用动词的过去分词形式作定语。故选B。 2. “make+复合宾语”结构 (教材原句)The railway has also made the transport of food easier. (教材原句)The bridge made it convenient for the villagers to travel across the river to the city. make后常跟复合宾语结构。当宾语较长时，常用it作形式宾语，而将真正的宾语不定式结构至于末尾，形成“make it+宾补+to do”结构。 如：The new road made our life better. 新路让我们的生活变好了。 The port makes it possible for villagers to sell goods far away.这座港口让村民把货物卖到远方成为可 能。 [随学随练] 单项填空 —Look! A ________ robot! —Yes, it often helps Mom ________ housework. A．cleaning, doing B．cleaning, do C．clean, with 【答案】B 【详解】句意：——看！一个清洁机器人！——是的，它经常帮助妈妈做家务。 cleaning清洁；doing做；clean打扫；with用。第一空表示机器人的功能，用现在分词cleaning修饰robot，意为“清洁机器人”；第二空考查help sb. (to) do sth.结构，意为“帮助某人做某事”，后接动词原形do。 3. 现在分词作定语 (教材原句)Our farm has a lot of laying eggs. (教材原句)Over the next 60 years, workers planted bushes and trees, creating the world's biggest man-made forest. laying和creating都是现在分词形式。前者用作定语修饰eggs；后者用作结果状语。 现在分词作定语时，通常表示主动关系或用于表用途，特征等。 现在分词作状语时，与其逻辑主语(动词的实际发出者)构成主动关系。 如：swimming pool 游泳池 The manager talking with villagers is very kind. 正在和村民交谈的经理十分和善。 He sat there, discussing business with the manager. 他坐在那儿，和经理商谈生意。 [随学随练] 单项填空 The old man walks slowly to his home, ________ a large bag on his back. A．carries B．carrying C．carry D．to carry 【答案】B 【详解】句意：老人背着一个大袋子慢慢地走回家。 根据“The old man walks slowly to his home…a large bag on his back.”可知，句子已有谓语动词walks，且无连词，故空处需用非谓语动词。老人与“背”之间是主动关系，且表示伴随状态，应用现在分词形式。应填carrying。 4. it作形式主语 (教材原句)It's amazing how much we have achieved together. 本句中it用作形式主语，真正的主语是后面的主语从句。 如：It is surprising how much benefit locals have got. 当地人收获的巨大益处令人吃惊。 [随学随练] 单项填空 —How did you feel about his success? —________ that he finished the difficult project all by himself. A．It amazed B．He was amazing C．It was amazing D．He was amazed 【答案】C 【详解】句意：——你如何看待他的成功？——他独自完成了这个艰难的项目，真是令人惊讶。 It amazed它使惊讶；He was amazing他令人惊讶；It was amazing这很令人惊讶；He was amazed他感到惊讶。此处是指代“他独自完成难题”这件事，修饰事物要用amazing，且需用it作形式主语构成固定句型，It was amazing符合语境。 5、 知识过关练习 1. 词汇填空  根据据提示填写正确形式的单词，每空一词。 (1) The Internet makes it ________ (方便的) for us to communicate with each other. 【答案】convenient 【详解】句意：互联网让我们彼此交流更加便捷。“方便的”对应形容词为convenient。 (2) But now, it’s easy for them to visit China and they will choose the ________ (首都)—Beijing as their first station. 【答案】capital 【详解】句意：但现在，他们来中国旅游很容易，他们会选择首都——北京作为他们的第一站。根据中文提示可知，“首都”对应的英文是capital，是名词，此处作宾语。 (3) They all believed their creative design would _________ (带领) them to the first prize. 【答案】lead 【详解】句意：他们都相信他们富有创意的设计会带领他们赢得一等奖。“带领”对应的英文单词是“lead”，又因为would是情态动词，其后接动词原形。 (4) How many times has your father been to Beijing on ________ (公事，生意)? 【答案】business 【详解】句意：你爸爸去北京出差过几次了？根据中文提示，可知这里词组on business表示“出差”。 (5) Drinking some hot water can ________ (减轻，缓解) your stomach pain a little. 【答案】ease 【详解】句意：喝一些热水能稍微缓解你的胃痛。减轻；缓解，“ease”，动词，情态动词“can”后接动词原形，故填ease。 (6) Lin Hai’s mother is a __________（经理）of a company. 【答案】manager 【详解】句意：林海的妈妈是一家公司的经理。根据所给中文可知，“经理”manager，根据“a”可知，此处应用单数形式。故填manager。 (7) There used to be ________ (狭窄的) streets and roads in my hometown.
