They can absorb carbon dioxide from the air and release oxygen, which is vital for humans and animals to breathe. Also, trees can provide shelter and food for many animals. We humans also get numerous benefits from trees. There are mainly two categories of trees: deciduous trees and evergreen trees. Deciduous trees usually lose their leaves in autumn. You can identify some of them by the shape and color of their leaves. Evergreen trees keep their leaves all year round. You can often see them in parks and along streets. If you observe the trees around you, you will notice their different characteristics. Some trees are very tall, while some are relatively short. Their trunks can be thick or thin. And most of them have a beautiful appearance. Thanks to these trees, our environment becomes more comfortable and habitable. ( )26. We need a lot of trees around us because _______. A. trees look beautiful B. trees can produce oxygen we need C. trees are easy to plant D. we like the shade of trees ( )27. There are many trees around us because _______. A. animals don't rely on trees B. humans don't need trees for building materials C. both humans and animals depend on trees to survive D. trees can make the city more modern ( )28. There are _______ evergreen trees than deciduous trees in some cold regions. A. much fewer B. much more C. about the same number D. much larger ( )29. Which of the following is NOT related to trees? A. Wooden chair. B. Apple. C. Steel frame. D. Bird's nest. ( )30. Which is the best title of this passage? A. Trees in Our Life B. Forest and Animals C. Live in a Green World D. Oxygen and Trees (B) How do different creatures communicate with one another? They each have their unique ways of getting messages across. In fact, these are like special "languages" made up of various signals, and each signal has its own significance. Take ants for example. When an ant discovers a source of food, it leaves a chemical trail on the ground as it heads back to the nest. Other ants can follow this trail to find the food. This chemical signal is their way of communicating the location of resources. Some animals express their emotions through specific sounds. For instance, when a cat is feeling threatened or annoyed, it hisses. When you hear this sound, it's a sign that you should give it some space. Whales can produce a wide range of sounds underwater that can convey different messages, like warnings to other whales or calls to find a mate. Humans, on the other hand, rely on spoken languages and written words. We can have face-to-face conversations to share our thoughts and experiences. We can write in diaries or books to record events for future reference. We can even use modern technology to send emails or text messages to people in distant places. Now, based on the above information, judge whether the following statements are true (T) or false (F). ( )31. Ants and whales both use chemical signals to communicate. ( )32. When a cat hisses, it means it's happy and wants to play with you. ( )33. Whales can make different sounds underwater to express different meanings. ( )34. Humans can communicate with others far away in many ways, but animals can't. ( )35. Creatures use different signals to communicate, and these signals play an important role in their lives. (C) We know that numerous animals don't always stay put. Insects, reptiles and other creatures shift from one area to another at specific times. They do this for various reasons: the majority of them relocate to obtain food more readily, while others leave their habitats because of changes in environmental conditions or to avoid overcrowding. When the temperature drops in winter, many birds fly to warmer regions in search of food. Some turtles lay their eggs on sandy beaches and then move to deeper waters to feed. One of the most well-known migrations is that of the eel. This fish is born in the ocean but travels a long distance to freshwater rivers. It spends a significant part of its life there. When it reaches maturity, it heads back to the ocean where it was born to reproduce and eventually die. In some mountainous areas, there is a type of squirrel. When their living spaces become too crowded with too many of their kind, they leave their cozy nests among the trees and move down to the valleys. Sometimes, they even venture as far as the edges of lakes, and unfortunately, some of them may meet danger along the way. Recently, researchers have been observing the migration of a particular kind of crab. Every year, when the season with strong winds and heavy rains arrives, these crabs form a long line and start crawling along the seabed. No one really understands why they do this or where exactly they are going. So, sometimes we can figure out the motives behind the movements of living beings from one place to another, but at other times, it remains a mystery. Maybe all living things just have an instinct to explore new places. Answer the following questions according to the passage. 36. What's the main reason for most animals to change their living places? 37. In the passage, find a word which has the same meaning as "the regular movement of a group of animals from one area to another area", and write it down. 38. In the second paragraph, the underlined word "There" refers to which place? 39. Why does the eel return to its birthplace? 40. When do the crabs start to move to other places? 第二部分 写作（25分） Ⅰ. 词汇。（10分） (A)根据句意及首字母提示补全单词。 1. We should try our best to s_______ the environment.

C。share sth. with sb. “与某人分享某物”，talk with sb. “与某人交谈”；say 后直接加说话内容；speak 后常加语言。这里是分享消息，所以选 C。 2. D。those 指代前面提到的复数名词 the trees，避免重复。this/that 指代单数；these 虽指代复数但不能用于比较级中代替前面提到的复数名词。 3. A。keep sth. tidy “保持某物整洁”，noisy “吵闹的”；crowded “拥挤的”；dirty “脏的”，教室应该保持整洁，所以选 A。 4. B。millions of “数以百万计的”，表示模糊数量，具体数字 + million + 名词复数，million 后不加 s 和 of，所以选 B。 5. B。三者比较用最高级，形容词最高级前要加 the，这里是说红色的裙子看起来更漂亮，是两者比较，所以用比较级 more beautiful。 6. A。live on “以……为食”，熊猫以竹子为食，所以选 A。 7. B。people 是可数名词复数，用 fewer 修饰，less 修饰不可数名词，little 和 few 表示否定意义“几乎没有”，这里是说用更少的人，所以选 B。 8.

What's your hobby? 解析：根据下文B回答“I like painting.”可知，A在这里是询问B的爱好是什么，所以用这个句子来提问比较合适，符合语境中A正在做关于爱好的项目，想要了解B爱好情况这一逻辑。 2. I think sports are more interesting. 解析：前文B说喜欢绘画，A觉得绘画有点孤独，这里A表达自己认为体育类活动更有意思的观点，与后面A表明自己喜欢打篮球相呼应，起到了话题转换以及对比阐述自己想法的作用。 3. It's really fun. 解析：上一句A表明自己喜欢打篮球，这里进一步阐述喜欢打篮球的原因，说打篮球很有趣，对喜欢的爱好进行简单描述，符合日常交流中表达喜好及原因的逻辑。 4. Because it can bring me a lot of joy and I can make many friends when playing it. 解析：上文B问“Why do you like it?”，这里需要用because来引出喜欢打篮球的原因，回答中提到打篮球能带来快乐还能交到很多朋友，合理地解释了喜爱这项运动的缘由，贴合日常交际中解释喜好原因的情景。 5. I think hobbies can make our life more colorful. 解析：前面提到和朋友打篮球很愉快，这里进一步升华话题，表达自己对于爱好的看法，认为爱好能让生活更加丰富多彩，使整个对话更有深度，也符合两人讨论爱好对生活影响的对话情境。 Ⅲ. 16.

A。从后文提到砍树、森林消失、河流污染等内容可知是人类从地球索取太多，而不是仅从天空、海洋或者山脉，所以选A。 21. B。die out是“灭绝”的意思，这里说因为河流被污染等原因一些鱼面临灭绝的危险，eating是“吃”，growing是“生长”，swimming是“游泳”，不符合语境，所以选B。 22.

When an ant discovers a source of food, it leaves a chemical trail on the ground as it heads back to the nest. Other ants can follow this trail to find the food. This chemical signal is their way of communicating the location of resources.（以蚂蚁为例。当一只蚂蚁发现食物来源时，它在返回巢穴的途中会在地面上留下一条化学痕迹。其他蚂蚁可以沿着这条痕迹找到食物。这种化学信号是它们传递资源位置的交流方式。）”位于第二段第1 4句；“Whales can produce a wide range of sounds underwater that can convey different messages, like warnings to other whales or calls to find a mate.（鲸鱼可以在水下发出各种各样的声音，这些声音可以传达不同的信息，比如对其他鲸鱼的警告或寻找配偶的呼唤。）”位于第三段第3句。 解析：从文中可知蚂蚁是通过留下化学痕迹这种化学信号来交流食物位置信息的，而鲸鱼是通过在水下发出声音来传达不同消息，并非使用化学信号交流，所以该说法错误。 第32题 答案：F 定位信息及翻译：“For instance, when a cat is feeling threatened or annoyed, it hisses. When you hear this sound, it's a sign that you should give it some space.（例如，当猫感到受到威胁或恼怒时，它会发出嘶嘶声。当你听到这种声音时，这是一个你应该给它一些空间的信号。）”位于第三段第2句。 解析：文中明确表明猫发出嘶嘶声意味着它感觉受到威胁或被惹恼了，这时人们需要给它空间，而不是表示它开心想玩耍，所以该说法不符合文意，答案为F。 第33题 答案：T 定位信息及翻译：“Whales can produce a wide range of sounds underwater that can convey different messages, like warnings to other whales or calls to find a mate.（鲸鱼可以在水下发出各种各样的声音，这些声音可以传达不同的信息，比如对其他鲸鱼的警告或寻找配偶的呼唤。）”位于第三段第3句。 解析：文中清晰提到鲸鱼能在水下发出多种声音来表达像发出警告、寻找配偶等不同含义，与题目表述相符，所以答案为T。 第34题 答案：T 定位信息及翻译：“We can even use modern technology to send emails or text messages to people in distant places.（我们甚至可以利用现代技术向远方的人发送电子邮件或短信。）”位于第四段第3句；文中前面介绍动物交流方式时未体现有类似远距离交流的手段（如第二段介绍蚂蚁、第三段介绍猫和鲸鱼的交流方式等）。 解析：人类能够借助如电子邮件、短信等多种现代技术与远方的人进行交流，反观文中所提及的动物的交流方式，像蚂蚁通过化学痕迹、动物通过声音等，并没有像人类这样多样的远距离交流方式，所以该说法正确，答案为T。 第35题 答案：T 定位信息及翻译：“How do different creatures communicate with one another? They each have their unique ways of getting messages across. In fact, these are like special "languages" made up of various signals, and each signal has its own significance.（不同的生物是如何相互交流的呢？它们各自都有独特的传递信息的方式。事实上，这些就像是由各种信号组成的特殊‘语言’，而且每个信号都有其自身的意义。）”位于第一段第1 3句；文中后续举例蚂蚁用化学痕迹找食物、猫用声音表达情绪、鲸鱼用声音传递不同消息等内容也体现了信号在它们生活中的作用。 解析：文章开头就点明不同生物有不同的交流信号，且后文所举的各种动物交流的例子都能看出这些信号对它们寻找食物、表达情感、寻找配偶等生活方面起着重要作用，所以该说法正确，答案为T。 (C) 36. What's the main reason for most animals to change their living places? 答案：To obtain food more readily. 定位信息及翻译：“They do this for various reasons: the majority of them relocate to obtain food more readily, while others leave their habitats because of changes in environmental conditions or to avoid overcrowding.（它们这样做有各种各样的原因：它们中的大多数迁移是为了更容易地获取食物，而其他的则因为环境条件的变化或为了避免过于拥挤而离开它们的栖息地。）”位于第一段第3句。 解析：从文中此句可以直接明确看出大多数动物改变生活地点的主要原因是更容易地获取食物。 37. In the passage, find a word which has the same meaning as "the regular movement of a group of animals from one area to another area", and write it down. 答案：Migration 定位信息及翻译：“The most famous migration(迁移)is the migration of fish, which is called “salmon”(鲑鱼).（最著名的迁移是鱼类的迁移，被称作‘鲑鱼’的那种鱼的迁移就是典型例子。）”以及文中其他多处出现“migration”描述动物迁移行为的地方，例如第三段在讲螃蟹迁移时也围绕“migration”相关内容展开等。“migration”本身的意思就是“（动物的）迁徙；迁移；移居”，符合题目所要求的含义。它在文中多处出现用于描述动物群体从一个地区到另一个地区的规律性移动情况。 解析：根据对单词含义的理解以及在文中对动物群体移动情况描述的语境，“migration”一词准确表达了“the regular movement of a group of animals from one area to another area”的意思。 38. In the second paragraph, the underlined word "There" refers to which place? 答案：Freshwater rivers. 定位信息及翻译：“This fish is born in the ocean but travels a long distance to freshwater rivers. There it spends its life.（这种鱼出生在海洋，但会游很长距离到淡水河。在那里它度过一生。）”位于第二段第3、4句。 解析：前一句提到鱼游到淡水河，紧接着说“There it spends its life”，按照指代逻辑，“There”指代的就是前面提到的鱼游去的“freshwater rivers”这个地方。 39. Why does the eel return to its birthplace? 答案：To reproduce and eventually die. 定位信息及翻译：“When it reaches maturity, it heads back to the ocean where it was born to reproduce and eventually die.（当它成熟时，它会回到它出生的海洋去繁殖并最终死去。）”位于第二段第5句。 解析：文中明确说明了鳗鱼成熟后回到出生地的目的就是去繁殖然后死去，从这句内容可以直接得出答案。 40. When do the crabs start to move to other places? 答案：When the season with strong winds and heavy rains arrives. 定位信息及翻译：“Every year, when the season with strong winds and heavy rains arrives, these crabs form a long line and start crawling along the seabed.（每年，当狂风暴雨的季节来临的时候，这些螃蟹排成一长队，开始沿着海底爬行。）”位于第三段第2句。 解析：此句清晰表明了螃蟹开始向其他地方移动的时间条件，就是当狂风暴雨的季节到来之时。 第二部分 写作 Ⅰ. 1. save 解析：根据后句“It's our duty to make the earth a better place to live in.”可知是要尽力拯救环境，“save”表示“拯救；挽救”，符合句意，首字母也符合要求，在句中构成“try one's best to do sth.”（尽力做某事）的结构。 2. birds 解析：从“They build their nests in the trees and sing lovely songs.”能判断出描述的是鸟，“bird”是“鸟”的意思，many 后接可数名词复数，所以填“birds”，首字母符合题意且符合句子语境。 3. population 解析：“getting larger and larger”以及“More and more people come to live and work here.”都提示说的是城市人口在增多，“population”意为“人口”，符合语境，首字母也相符。 4. camping 解析：“go camping”是固定短语，意为“去露营”，句中说在周末去山里做这件事，能享受新鲜空气和美景，符合逻辑，首字母“c”也满足题意。 5. brain 解析：根据后句“It helps us to think and remember things.”可知描述的是大脑的功能，“brain”表示“大脑”，符合句意及首字母要求。 (B) 6. chain 解析：“food chain”是固定短语，意为“食物链”，此处说老虎在食物链的顶端，符合短语搭配和句子意思。 7. asleep 解析：“be asleep”表示“睡着的”状态，句中说别制造太多噪音，因为宝宝睡着了，符合语境要求。 8. area 解析：“area”表示“地区；区域”，这里说家乡周围的地区自然资源丰富，符合句子表达的含义。 9. hide 解析：“to”后接动词原形，构成不定式，“hide”表示“藏；隐藏”，符合冬天动物找温暖地方藏起来的语境。 10. protect 解析：“should”是情态动词，后接动词原形，“protect”意为“保护”，句子表达应该保护野生动物及其栖息地的意思，符合题意。 Ⅱ. 11. taller 解析：根据句中的“than”可知要用比较级形式，“tall”的比较级是“taller”，表示“更高的”，句子是在将“我妹妹”和“我”的身高作比较，符合语境要求。 12. jumped 解析：“when its owner came back home”是一般过去时的时间状语从句，主从句时态要保持一致，所以主句也用一般过去时，“jump”的过去式是“jumped”，描述狗当时的动作情况。 13. polluted 解析：此处需要一个形容词来修饰“air”，“pollute”是动词，其形容词形式“polluted”表示“受污染的”，符合“待在受污染的空气中对健康不好”这一语境。 14. swam 解析：“when they heard the loud noise”表明句子是在描述过去发生的事情，所以主句也要用一般过去时，“swim”的过去式是“swam”，体现鱼当时的行为动作。 15. destruction 解析：“from”是介词，后接名词作宾语，“destroy”是动词，其名词形式“destruction”表示“破坏”，符合句子“采取措施保护环境保护其免受破坏”的意思表达。 Ⅲ. 参考范文 Dear Lin Yue, I'm glad to receive your email. There are many different kinds of animals in Hangzhou. You can often see mandarin ducks and other birds beside the West Lake. And there are also squirrels playing in the parks. People here attach great importance to animal protection. They've set up some protected areas. Volunteers often go to publicize knowledge about it and feed animals with healthy food. I think it's great and hope more people will join in protecting animals. Best wishes! Wang Chen 学科网（北京）股份有限公司 $$
