Sun Wukong is p________ among children. He’s also a ________ of bravery. 【答案】 greatest popular/opular symbol 【详解】句意：《西游记》是中国最伟大的经典著作之一。孙悟空深受孩子们喜爱。他也是勇敢的象征。第一空考查固定结构“one of the+形容词最高级+名词复数”，意为“最……之一”，great的最高级是 greatest。第二空结合语境及首字母，考查短语be popular among...，意为“在……中受欢迎”。第三空表达“孙悟空是勇敢的象征”，symbol意为“象征”，冠词a后接名词单数，a symbol of意为“……的象征”。故填greatest；popular；symbol。 二、单项选择 1．The Bamboo Sea is in Sichuan, ________ largest and most famous bamboo forest in China.

A．What B．How C．What a D．How a 【答案】A 【详解】句意：我在那里学到了多么有趣的事情啊！ 感叹句结构中，中心词是名词用What引导，中心词是形容词或副词用How引导。本句中心词是名词复数things，符合What+形容词+可数名词复数+主语+谓语!的结构。What a后面需要接单数可数名词。故填What。 3．—I think home is ________ place in the world. —I agree. East or west, home is the best. A．warm B．warmer C．warmest D．the warmest 【答案】D 【详解】句意：——我认为家是世界上最温暖的地方。——我同意。金窝银窝不如自家草窝。 根据“in the world”可知是在世界范围内进行比较，应使用形容词最高级，且形容词最高级前需加定冠词the。应填the warmest。 4．English is a useful ________ to introduce Chinese culture to the world.

It can “eat” small 1 and other insects. How does the plant catch them? The plant has leaves that look like green mouths with 2 “teeth” around the edges (边缘). 3 , there are some small hairs inside the leaves. When an insect 4 these hairs, the leaves close quickly. Then, the plant turns it into food. If the leaves catch a raindrop by accident, they will open again soon. This clever plant knows the 5 between food and non-food. 【答案】1．ants 2．tiny 3．In fact 4．touches 5．difference 【导语】本文是一篇说明文。文章主要介绍了捕蝇草这种神奇的植物，详细描述了它捕捉昆虫的独特构造和原理：叶子边缘有细小的“牙齿”，内部有感应毛发，当昆虫触碰毛发时叶子会迅速闭合，且它能区分食物和非食物。 【详解】1．句意：它能“吃”小蚂蚁和其他昆虫。空格处作动词eat的宾语，且被形容词small修饰，需填入名词；根据后文and other insects可知此处应填一种昆虫；备选词ant意为“蚂蚁”，因前面没有冠词a/an，故需用复数形式ants表示泛指。故填ants。 2．句意：这种植物的叶子看起来像绿色的嘴巴，边缘长着微小的“牙齿”。空格位于介词with之后、名词teeth之前，需填入形容词作定语；结合语境形容牙齿的大小，备选词tiny意为“极小的/微小的”，符合捕蝇草边缘刺毛的特征。故填tiny。 3．句意：事实上，叶子内部有一些细小的毛发。空格位于句首，用逗号与主句隔开，通常填入副词或介词短语作状语；结合上下文，前文讲外部特征，此处进一步补充内部构造，备选词in fact意为“事实上/实际上”，置于句首首字母需大写。故填In fact。 4．句意：当昆虫触碰这些毛发时，叶子会迅速闭合。分析句子结构可知，When引导的时间状语从句中缺少谓语动词；主语an insect是第三人称单数，且全文描述客观事实用一般现在时，故动词需用三单形式；备选词touch意为“触碰”，变为touches。故填touches。 5．句意：这种聪明的植物知道食物和非食物之间的区别。空格位于定冠词the之后、介词between之前，需填入名词；固定搭配the difference between A and B意为“A和B之间的区别”；备选词different是形容词，其名词形式为difference。故填difference。 二、短文填空 请阅读下面短文，根据语篇内容，在空白处填入恰当的单词，使短文通顺、连贯，并将答案写在答题卡相应的位置上。每空一词。 Plum blossom (梅花) is a special flower in Chinese culture.

Many people write poems (诗) and draw pictures to show their love for this wonderful flower. 【答案】1．is 2．but 3．against 4．hope 5．like/love/enjoy 【导语】本文介绍了梅花在中国文化中的特殊地位，描述梅花的外形、不畏风雪的特质，它象征希望，人们喜爱梅花不仅因为外形，更敬佩它坚韧的精神。 【详解】1．句意：它是中国最受人喜爱的花卉之一。主语It，一般现在时，be动词使用is。 2．句意：它看上去朴素但是美丽。simple和beautiful构成转折关系，连词but表示“但是”。 3．句意：它们抵御寒风与大雪。固定搭配fight against，意为“对抗；抵御”。 4．句意：它们也是希望的象征。后文“Their blooming tells people that spring is not far away. They bring people hope”提示，此处表示梅花是希望的象征，此处填hope。 5．句意：人们喜爱梅花，不仅是因为它的美丽，还因为它顽强的精神。like/love/enjoy均可表达喜爱，全文一般现在时，主语People，动词用原形。 三、补全对话 根据对话内容，选出恰当的句子补全对话，有两个选项是多余的。 Mike: Look, Amy! 1 Amy: Yes. This plant can reach up to 25 metres. It is a kind of interesting plant. Mike: 2 It looks like a handsome boy. Amy: Yes, and it is a kind of amazing plant. 3 And one day, if it begins to grow, it will grow up twenty centimetres every day. Mike: But why can’t we see the flowers? Amy: The bamboo can only blossom (开花) for once in their lives. 4 Mike: That’s too bad. 5 It’s cool in the summer. Amy: That’s true. A．It has a long stem and green leaves. B．How tall the bamboo is!

I’ll show you something amazing.” My friend Zhu decided 1 me to his grandparents’ garden. We walked for 40 minutes, we arrived at Qiaojia Road. 2 , we stopped in front of the small garden. “Here we are,” my friend said excitedly. “Excuse me, 3 where is the amazing thing?” I asked. “Isn’t the tall ginkgo tree beautiful?” My friend asked. “Yes,” I answered. “But ginkgo trees are everywhere in our country.” “This one is 4 ,” said Zhu. “It’s over 700 years old.” The tree looked healthy. But my friend said luck wasn’t always on its side. During the Kangxi years of the Qing Dynasty (清朝), 5 wanted to cut it down. Luckily, Zhang Xiyi, a kind man, 6 it from the axe (斧头). And in its early years, insects attacked (攻击) it and lightning hit it. It stood still 7 so many challenges (挑战). Many people believed that the tree was magical. They used to pray (祈祷) under it, hoping it would bring them hope and long life. They had the 8 of seeing many of their dreams come true. I looked at the “magical” tree and its fan-shaped leaves in surprise. “Amazing!” I said. Last weekend, I visited the tree again. I thought it looked much 9 . It was like a lonely old man. It was always ready to 10 its stories, if someone would like to stop and listen. 1．A．takes B．took C．to take D．take 2．A．Finally B．Really C．Actually D．Luckily 3．A．and B．but C．or D．so 4．A．tall B．difficult C．boring D．different 5．A．someone B．anyone C．nobody D．everyone 6．A．found B．caught C．saved D．saw 7．A．through B．across C．past D．around 8．A．love B．feeling C．pleasure D．success 9．A．healthily B．more healthily C．healthy D．healthier 10．A．speak B．tell C．talk D．say 【答案】 1．C 2．A 3．B 4．D 5．A 6．C 7．A 8．C 9．D 10．B 【导语】本文讲述了作者朋友带作者去参观一棵七百多年的银杏树，介绍了树的历史及人们对其的敬仰，表达了作者对古树的赞叹。 【详解】1．句意：我的朋友朱决定带我去他祖父母的花园。 “decide to do sth.”为固定搭配，意为“决定做某事”，此处需用动词不定式to take作宾语。 2．句意：最后，我们在小花园前停了下来。 根据上文“We walked for 40 minutes, we arrived at Qiaojia Road.”可知，经过一段时间后“最终”到达了小花园，Finally“最后”符合语境。Really真正地；Actually实际上；Luckily幸运地，均不符合时间逻辑。 3．句意：“打扰一下，但是神奇的东西在哪里？”我问道。 根据前文朋友说“Here we are”，后文作者问“ where is the amazing thing”，作者跟着朋友去看令人惊奇的东西，但朋友最后停留在一个小花园，所以作者问东西在何处，此处句意发生了转折，but“但是”符合语境。and和；or或者；so所以，均无转折意味。 4．句意：朱说：“这一棵是不同的。” 根据上文“ginkgo trees are everywhere in our country”和后文“It’s over 700 years old.”可知，这棵树很特别，与其他银杏树不同，different“不同的”符合语境。tall高的；difficult困难的；boring无聊的，均不符合语境。 5．句意：清朝康熙年间，有人想砍倒它。 根据后文“Luckily, Zhang Xiyi ... it from the axe (斧头).”可知，有人想砍掉这棵树，但是被张曦义救了下来，此句为肯定句，someone“某人”符合语境。anyone任何人；nobody没人；everyone每个人，均语意不通。 6．句意：幸运的是，张曦义，一个政府官员，把它从斧头下救了下来。 根据上文“wanted to cut it down”和后文“from the axe”及语境可知，是“拯救”了树，saved“拯救”符合语境。found发现；caught抓住；saw看见，均不符合语境。 7．句意：它历经这么多挑战依然屹立。 根据后文“so many challenges”可知，此处指历经挑战，through“历经”符合语境。across横跨；past经过；around围绕，均不能与“challenges”搭配。 8．句意：他们很高兴看到许多梦想成真。 人们在树下祈祷，梦想成真后自然会感到愉快，固定搭配have the pleasure of doing sth.意为“做某事感到开心愉快”，pleasure“快乐，愉快”符合语境。love爱；feeling感觉；success成功，均不符合语境。 9．句意：我觉得它看起来更健康了。 “looked”是系动词，后接形容词作表语；much用来修饰形容词比较级，表示“……得多”，因此选形容词比较级healthier“更健康的”。healthily健康地，副词原级；more healthily更健康地，副词比较级；healthy健康的，形容词原级，均不符合语法要求。 10．句意：如果有人愿意停下来听，它总是愿意讲它的故事。 固定搭配“tell stories”意为“讲故事”。speak讲（强调动作）；talk谈话（强调相互交流）；say说（强调内容），均不能与“stories”搭配。 二、阅读理解 （A） What is bamboo? Is it a tall, thin tree or a type of grass? To many people’s surprise, it is a fast-growing type (种类) of grass! Bamboo grows naturally in Africa, Asia, America and Australia. Bamboo has been used for thousands of years and in many countries. China, one of the oldest and largest producers (生产国) of bamboo, has been making use of it for more than 5000 years. In ancient times, Chinese people used it for things like clothes, houses and boats. One of the world’s oldest water pipes (水管) was made from bamboo too. In India, bamboo was important for traditional arts and musical instruments. In Africa, people once used bamboo for buildings, food and even medicine (药). Over time, the material has become more and more popular. Even today, new uses are still being discovered and developed. As people look for a material that is good for the environment, bamboo often tops the list. It gives off about 35% more O2 than a tree of similar size. It takes in a lot of CO2 as well. Also, bamboo grows very fast—some can grow over a metre a day! This makes it a good renewable resource (可再生资源). As a result, bamboo seems like a perfect choice for everything. It is an excellent building material. It can be used to make soft and fast-drying clothes. It’s strong enough to make beautiful chairs, beds and tables. It can be used for kitchen products that help stop bacteria (细菌). It seems as if its uses are never-ending. It will help us live in a better, greener world. 1．Why does the writer ask questions at the beginning of the text? A．To show new research findings. B．To compare different types of bamboos. C．To catch people’s attention. D．To explain people’s thoughts. 2．According to the text, what is bamboo? A．A tall and thin tree. B．A fast-growing type of grass. C．A kind of water plant. D．A special flower. 3．According to the text, what was one of the uses of bamboo in Africa? A．Making musical instruments. B．Making buildings. C．Creating ancient water pipes. D．Creating kitchen tools. 4．Why does the writer say bamboo “often tops the list” as a good renewable resource in paragraph 4? A．Because it is the cheapest material. B．Because it has the longest history of use. C．Because it is good for environment and grows fast. D．Because it can be used to make musical instruments. 5．Which of the following is the best title for this text? A．Facts about bamboo B．History of bamboo C．Reasons for using bamboo D．Types of bamboo 【答案】1．C 2．B 3．B 4．C 5．A 【导语】本文介绍了竹子的基本属性（属于草本植物而非树木）、全球分布、悠久的使用历史、环保优势（释氧吸碳、生长迅速）以及广泛的现代用途，展现了竹子作为一种绿色可再生资源的巨大价值。 【详解】1．文章开篇用“What is bamboo? Is it a tall, thin tree or a type of grass?”两个问句引出话题，目的是引起读者的注意和兴趣，引出下文对竹子的介绍。 2．第一段“To many people’s surprise, it is a fast-growing type of grass!”，明确说明竹子是一种生长迅速的草本植物。 3．第二段“In Africa, people once used bamboo for buildings, food and even medicine.”，明确说明竹子曾在非洲用于建造房屋。 4．第四段指出了竹子作为可再生资源的两个优势：对环境友好（释氧吸碳）和生长迅速（some can grow over a metre a day）。 5．全文从竹子的属性、分布、历史、环保优势、现代用途等多个方面进行了介绍，属于对竹子的事实性说明，因此“关于竹子的事实”最贴切。 （B） What is bamboo? Is it a tall, thin tree or a kind of grass? For many people, it is a type of fast-growing grass! Bamboo grows naturally in Africa, Asia, America, and Australia. Bamboo has been used for thousands of years in many countries. China is one of the countries with a long history of using it—over 5,000 years. In ancient (古代的) China, people used bamboo to make many things, like clothes, houses, and boats. Chinese people loved bamboo so much that they wrote many poems about it. In India, bamboo was important for traditional arts and musical instruments. In Africa, people once used it to build houses, make food and even for medicine. Bamboo has become more and more popular. Even now, people are still finding new ways to use it. Today people want something that is good for the environment. Bamboo is the best choice. It produces about 35% more oxygen (氧气) than a tree of the same size. It also takes in lots of carbon dioxide (二氧化碳). Also, bamboo grows very fast—some can grow over one meter a day! This makes it a good renewable resource (可再生资源). So bamboo is a perfect choice for many things. It’s a great building material. It can be used to make soft and fast-drying clothes. It’s strong enough to make nice chairs, beds, and tables. It can even be used for kitchen products that stop bacteria (细菌). Its uses seem endless, and it will help us live in a better, greener world as scientists study it more. 6．How long has China been using bamboo? A．For about 1,000 years. B．For more than 5,000 years. C．For less than 5,000 years. D．For 3,500 years. 7．What is Paragraph 2 mainly about? A．The history of growing bamboo in China. B．The cultural meaning of bamboo in China. C．The traditional uses of bamboo in different countries. D．The growing areas of bamboo in different countries. 8．What’s the meaning of underlined word “environment” in Paragraph 4? A．环境 B．宇宙 C．社会 D．自然 9．Why is bamboo good for the environment? A．It grows very slowly. B．It gives out less oxygen than trees. C．It takes in a lot of carbon dioxide. D．It is not a renewable resource. 10．What is the best title for the passage? A．How to Grow Bamboo Fast B．The History of Bamboo in China C．Bamboo vs. Trees: Who Is Better D．Bamboo: A Useful and Green Resource 【答案】6．B 7．C 8．A 9．C 10．D 【导语】本文是一篇说明文，文章主要介绍了竹子的定义、历史用途、环保特性（产氧、固碳、可再生）以及现代用途。 【详解】6．根据第二段第二句“China is one of the countries with a long history of using it—over 5,000 years.”可知，中国是使用竹子历史悠久的国家之一——超过 5000 年，故可推测出“over”意为“超过”，即more than。 7．第二段分别列举了中国（做衣服、房子、船等）、印度（传统艺术和乐器）以及非洲（建房子、食物、医药）对竹子的传统用途。因此该段主要讲述不同国家竹子的传统用途，选项C符合。 8．根据第四段第三句和第四句“It produces about 35% more oxygen (氧气) than a tree of the same size. It also takes in lots of carbon dioxide (二氧化碳).”可知竹子释放氧气、吸收二氧化碳，这些都和环境相关，environment意为“环境”符合。 9．根据第四段第四句“It also takes in lots of carbon dioxide (二氧化碳).”可知，竹子也吸收大量的二氧化碳，这是竹子对环境有益的原因之一，选项C符合语境。 10．通读全文可知，文章介绍了竹子的定义、历史用途、环保特性（产氧、固碳、可再生）以及现代用途。D项“竹子：一种有用且绿色的资源”最能概括全文主旨，涵盖了“有用”和“环保”两个核心点。 ( 1 / 6 ) 学科网（北京）股份有限公司 $ Unit 4 Amazing Plants and Animals 课时2 Section A Pronunciation&2a-2e 分层作业 A组 巩固过关 C组 思维拔高 B组 能力进阶 ( 词汇 ________ n. 竹子 ________ n. 折扇 ________ n. 绘画；画 ________ n. 文化 ________ n. 象征 ________ n. 工具 __________ n. 乐器；工具 _______ n. 嫩芽；笋 ________________ 在中国文化中 ____________ 建造房屋 ______________________ 最大的竹林 句型 1.

Is it a tall, thin tree or a type of grass? To many people’s surprise, it is a fast-growing type (种类) of grass! Bamboo grows naturally in Africa, Asia, America and Australia. Bamboo has been used for thousands of years and in many countries. China, one of the oldest and largest producers (生产国) of bamboo, has been making use of it for more than 5000 years. In ancient times, Chinese people used it for things like clothes, houses and boats. One of the world’s oldest water pipes (水管) was made from bamboo too. In India, bamboo was important for traditional arts and musical instruments. In Africa, people once used bamboo for buildings, food and even medicine (药). Over time, the material has become more and more popular. Even today, new uses are still being discovered and developed. As people look for a material that is good for the environment, bamboo often tops the list. It gives off about 35% more O2 than a tree of similar size. It takes in a lot of CO2 as well. Also, bamboo grows very fast—some can grow over a metre a day! This makes it a good renewable resource (可再生资源). As a result, bamboo seems like a perfect choice for everything. It is an excellent building material. It can be used to make soft and fast-drying clothes. It’s strong enough to make beautiful chairs, beds and tables. It can be used for kitchen products that help stop bacteria (细菌). It seems as if its uses are never-ending.
