Now it’s one of China’s biggest and most important cities. Over 40 years of development, the high-tech industries (高科技产业) have developed fast. Many companies set up their head offices in Shenzhen and many people from all over the country came to Shenzhen to find jobs. They even made their homes here. And the population of Shenzhen increased to more than 13,000,000 in 2019. With the fast development, many problems also appear in the city, especially air pollution. Sea pollution is a main problem too. The good news is that the government and people are trying their best together to improve the situation.

Normally green leaves turn red, orange, yellow, and finally brown. This is a 56 (nature) phenomenon. It is called “leaf phenology (叶片物候)”. However, because of 57 (change) climate, autumn is changing. According to a study, the season length is 58 (grow), meaning that it is taking longer for leaves to change their colors. And this is not the only way that climate change is destroying the season. “Trees are holding on to their leaves longer,” explained an expert. “In my own neighborhood, I feel 59 (curiosity) when I find that the leaves would drop a lot sooner 20 years ago 60 they do now.” Climate change isn’t only causing 61 leaves to change later. We can also expect later frost (霜) according to Dr Michael. Michael said, “That means pests (害虫) will be active for a longer time in autumn, causing a greater health 62 (risky) to human beings.” However, we may be able to avoid this 63 (develop). Michael said that 64 humans control their carbon dioxide emissions (二氧化碳排放), they can still stop the worst effects of climate change. “A new study has 65 (recent) shown that warming will likely stop after carbon emissions reach zero,” Michael said. 七、读写综合(本大题分为A、B两部分，共20分) A．回答问题(本题共5小题，每小题1分，共5分) 请阅读下面短文，根据所提供的信息，回答5个问题。要求所写答案语法正确、语义完整切题。 Chaka Salt Lake is a salt lake in Qinghai, China. Lying at an altitude of about 3,100 meters, it covers an area of about 105 square kilometers. It is rich in salt, with a heavy salt bed close to the lake surface. That makes the lake a main source (来源) of salt in our country. On a clear day, the lake offers the beautiful reflection (映像) of the blue sky. That is why people call it “Mirror of the Sky”. Because of its wonderful views, people see the lake as one of the “must-go” places in China. The beautiful sunrise and sunset views are the most attractive. Every July, large numbers of visitors begin to crowd into Chaka Salt Lake. And the situation usually lasts until the end of August. They just don’t want to miss the best time to go there. It is believed that with the summer breeze (微风), breathing in the salty air is especially good for health. If you want to go on a trip to the lake, the following tips may be helpful. ■ Do not eat the salt in the lake directly. ■ Wear sunglasses and a hat to protect you from the strong sunshine. ■ You can’t help taking photos, so you’d better take your camera with you. ■ Prepare some medicine for the weak and the elderly to deal with altitude sickness. When you travel to such a beautiful world of salt with snowy mountains and green grass around, you will feel like you are in a fairyland. 66．Where is Chaka Salt Lake? ___________________________________________________________ 67．What’s the area of Chaka Salt Lake? ___________________________________________________________ 68．Why do people see Chaka Salt Lake as one of the “must-go” places in China? ___________________________________________________________ 69．When do many visitors go to visit Chaka Salt Lake? ___________________________________________________________ 70．Why should people prepare medicine for the weak and the elderly? ___________________________________________________________ B.书面表达(本题15分) 71．假设你叫李明，得知你的外国朋友Peter计划来中国旅游，你打算给他写一封邮件，邀请他来惠州。请你根据以下思维导图内容提示用英文写一封邮件。 Dear Peter, I’m glad to hear that you are coming to China.Would you like to visit Huizhou?_________________ __________________________________________________________________________________________________ _______________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ I’m looking forward to your coming. Love,      Li Ming 参考答案 一、 1．depth 【详解】句意：这里的水有多深？由“the…of”可知，此处应填入名词。因此，空格处应将形容词deep转换为名词形式。deep的名词形式为depth，意为“深度”，符合句意。 2．the most important 【详解】句意：保护环境是我们必须做的最重要的事情之一。分析句子结构可知，本句是“one of the+形容词最高级+名词复数”结构，意为“最……的……之一”。形容词important为多音节词，其最高级形式为the most important。 3．clearer 【详解】句意：清理过后，河里的水看起来比以前更清澈了。looks是系动词，此处是形容词作表语，than表示比较，此处应用形容词比较级clearer。 4．to protect 【详解】句意：保护我们周围的野生动物很重要。It is important to do sth.“做某事很重要”，是固定句型，空处应是不定式to protect。 5．farthest 【详解】句意：长江在中国流经的距离最长。范围状语“in China”表明此处需用副词最高级形式。“far”的最高级为“farthest”，表示距离上的“最远”。 6．southern 【详解】句意：中国南部以其美丽的海滩而闻名。此处需用形容词修饰名词part，south的形容词形式为southern，表示“南部的，南方的”。故填southern。 7．wonders 【详解】句意：对大多数人来说，珠穆朗玛峰是世界上最伟大的奇迹之一。one of the + 形容词最高级+复数名词，意为“最……之一”，是固定句型；wonder“奇迹”，可数名词，其复数形式是wonders。 8．colourful 【详解】句意：你可以在水里看到五颜六色的鱼。此处需要一个形容词来修饰名词fish。colour的形容词形式为colourful，意为“五颜六色的、色彩鲜艳的”，故填colourful。 9．blind 【详解】句意：一些深海动物是盲的，但它们可以“看见”。be动词后接形容词作表语，blindness的形容词形式是blind，故填blind。 10．successfully 【详解】句意：经过数月的艰苦努力，他们最终成功地登上了山顶。修饰动词reached应该用副词，success的副词形式是successfully“成功地”。 二、 11． amazing abilities 【详解】原句中“非凡的”和“能力”是关键词，“非凡的”对应的英文形容词是amazing，“能力”对应的英文名词是abilities。分析句式结构，此处名词短语作have的宾语。由于主语Some animals为复数概念，名词需用复数形式。 12． twice as expensive as 【详解】原句中“两倍”是关键词，最常用的倍数表达结构是“倍数+as+形容词原级+as”，符合句中4个空结构，“两倍”单词是twice，这里的形容词用“昂贵的”expensive，故填twice；as；expensive；as。 13． reading more interesting 【详解】原句中“看”和“更有趣”是关键词。表示“看”的单词是read，作主语，需使用动名词reading；表示“更有趣”的单词是more interesting，比较级，对应空后的than。 14． millions of 【详解】原句中“数百万的”是关键词，对应的标准英文固定搭配是millions of，用来修饰可数名词复数，表示数量极多、数百万的。故填millions；of。 15． unforgettable experience 【详解】此处缺少“难忘的经历”，其英文表达为unforgettable experience，an后接名词单数形式。 16． is famous for name 【详解】be famous for“以……而闻名”，句子叙述事实，用一般现在时，主语“The park”是名词单数，be动词用is；name“给……起昵称”，主语是“we”，谓语动词用原形。 17． deal with 【详解】原句中“应对”是关键词，表示“应对”的动词短语是deal with，置于情态动词之后，应用动词短语原形。 18． full of determination 【详解】原句中“充满决心”是关键词，“充满”常见的英文表达是“be full of” ，“决心”常见英文表达为“determination”，所以“充满决心”对应的英文表达是“full of determination”。 19． in his lifetime 【详解】原句中“他一生中”是关键词，表示“在某人一生中”的介词短语是in one’s lifetime，主语为He，one’s应变为his。 20． by all means 【详解】此处缺少“尽一切办法”，其英文表达为by all means，是介词短语。 三、 21．C 22．A 23．B 24．C 25．A 26．A 27．B 28．B 29．A 30．C 【导语】本文介绍东非大裂谷的地位、地理位置与特殊地貌，讲解它的地质形成原因；同时介绍当地丰富的生物、长久的人类聚居历史。 21．句意：它是地球上世界最令人惊叹的地方之一。 固定结构：one of+the+形容词最高级+复数名词，表示“最……之一”。more amazing比较级、amazing原级均不符合此结构。 22．句意：许多人称它为“地质奇观”。 此处指代前文The East African Rift Valley，单数事物用it，人称代词宾格，作call的宾语。its物主代词、itself反身代词均不符合语境。 23．句意：科学家称，这条裂谷数百万年前因地壳运动而形成。 固定搭配as a result of“由于……”。the表特指、an后接元音音素开头单词均不符合此搭配。 24．句意：这里的地壳正在缓慢分裂。 be动词+现在分词构成现在进行时，表示动作正在发生，此处需用现在分词。move动词原形、moved过去分词/过去式，均不构成现在进行时。 25．句意：你可以在这片区域看到高山、深湖和活火山。 in this area“在这片区域”，大范围地域。on用于平面、物体表面；at用于小地点、具体点位。 26．句意：许多生物在东非大裂谷繁衍生息。 living things固定短语，意为“生物、生命体”。lively“活泼的、热闹的”、alive“活着的”，多作表语，不作定语。 27．句意：这里有斑马、长颈鹿等独特动物，还有各种各样色彩斑斓的鸟类。 固定搭配：as well as“以及、还有”。good“好的”、better“更好的”，无此搭配。 28．句意：当地人已经在此生活了数千年。 固定搭配：thousands of“成千上万的”，thousand前面要有具体数字、thousand’s所有格形式。 29．句意：如果有一天你来游览大裂谷，你会被它的自然之美震撼。 此处表示假设情况，if引导条件状语从句，表示“如果”。Though“虽然”，引导让步状语从句、Because“因为”，引导原因状语从句，均逻辑不通。 30．句意：它是一个了解地球历史与奇妙自然的绝佳地方。 固定句型：a perfect place to do sth.“做某事的好地方”，动词不定式to learn作后置定语。learn原形、learning动名词现在分词均不符合语法结构。 四、 31．B 32．A 33．C 34．A 35．C 36．B 37．A 38．B 39．C 40．C 【导语】本文讲述家乡多年来变化巨大，国家发展迅速，作者借读书了解变迁与传统文化，并期盼祖国愈发美好。 31．句意：这里有老旧的房屋和脏乱的道路。 上文“In the past”表明时态为一般过去时，there be句型遵循就近原则，空格后为复数名词“old houses”，be动词需用过去式were。 32．句意：中国正发展得十分迅速。 下文提到诸多伟大发明让生活更便利，能看出国家发展势头很快，fast可以修饰动词developing表示“发展迅速”；slowly“缓慢地”、late“迟地”、early“早早地”，都和文意逻辑相悖。 33．句意：我们可以乘坐高铁舒适地出行。 结合上下文高铁出行的生活体验，乘坐高铁出行体感安逸舒服，comfortably表示“舒适地”，契合出行体验；cheaply“廉价地”、sadly“难过地”、angrily“生气地”，均不符合出行语境。 34．句意：我们可以借助互联网轻点一下就能看遍世界。 with one click是固定搭配，表示“轻点鼠标、一键点击”，符合网络使用语境。 35．句意：好书能开阔我们的眼界、启迪我们的思想。 上文提到阅读是了解过去和现在的好方式，结合读书的益处，open one’s eyes为固定搭配，表示“开阔眼界”，贴合读书的益处；close、shut都表示“关闭”，turn意为“转动”，不符合短语搭配与语境。 36．句意：每当我有空，就坚持阅读。 keep on doing sth.是固定用法，表示“坚持做某事”，其后接动名词形式reading。 37．句意：我了解到了中国的巨大变化和传统文化。 上下文围绕了解国家发展、本土文化展开，此处修饰名词“culture”，traditional表示“传统的”，贴合文化搭配；lazy“懒惰的”、noisy“吵闹的”、quiet“安静的”，不符合语境。 38．句意：我希望我们可以努力学习，让我们的国家变得更加美丽。 空后为形容词比较级“more beautiful”，much可以用来修饰比较级，加强程度；many不能修饰比较级，more本身是比较级，most为最高级，用法均不符合语法规则。 39．句意：过往铭记历史，当下给予机遇，阅读让我们清晰地认识世界。 上文讲读书带来认知提升，阅读能让人看清读懂世界，clear符合文意；boring“无聊的”、strange“陌生的”、unknown“未知的”，都体现不出阅读带来的认知作用。 40．句意：我相信未来将会变得更加美好。 空后是比较级“better”，even可以修饰比较级，意为“甚至、越发”；very、quite、so都只能修饰形容词原级，不能修饰比较级。 五、 41．A 42．B 43．C 44．D 45．C 【导语】本文是一篇说明文，依次介绍一年四个季节各自的白昼长短、天气变化、植物特点以及人们的特色活动，整体简单介绍四季的不同特征。 41．春天段落明确提到：“Lots of plants start to grow”，由此可知春天到来时许多植物开始生长，其余选项分别对应秋冬夏的特点，因此该项正确。 42．夏天段落最后一句提到：“So it’s the best time to go to the beach”，直接说明夏天是去海边的最佳时节。 43．冬季段落介绍了天气状况、植物生长变化以及人们滑雪的活动，全文没有提及特色食物相关内容，因此文章没有谈论冬季的特色食物。 44．秋天段落写明：“Autumn is the harvest season because this is when most crops are ready to be harvested”，点明大部分农作物成熟可以收割，所以秋天是收获的季节。 45．文章开篇总述一年有四个季节，随后分段依次介绍春、夏、秋、冬四个季节的相关特点，整体是对四季的全面介绍，因此本文主旨为介绍一年四季。 46．C 47．D 48．C 49．D 50．A 【导语】本文是一篇说明文，主要介绍了深圳从过去的海边小镇发展为现代化大都市的过程，以及快速发展带来的环境问题。 46．第一段明确提到“Shenzhen is a beautiful and modern city and it’s in the southeast of China. It lies on the coast of the South China Sea.”，这是在直接陈述客观事实，而不是在做比较、提问或列举数字。 47．第二段明确提到“In 1978, there were only about 300,000 people, and most of them made a living by farming and fishing.”，这说明1978年深圳的人口大约是三十万。 48．第三段开头说“Thanks to China’s reform and opening-up policy (改革开放政策), Shenzhen has changed greatly.”，接着描述了高科技产业发展、公司设立总部、人口增长等，整段核心是深圳的发展变化。 49．最后一段明确提到“With the fast development, many problems also appear in the city, especially air pollution. Sea pollution is a main problem too.”，这说明深圳现在主要的污染问题是空气污染和海洋污染。 50．文章最后一句写道“When a city develops quickly, we should not forget to protect the environment.”，这是对环境保护的呼吁。可推测，接下来很自然地会讨论如何保护深圳的环境。 51．C 52．B 53．E 54．D 55．F 【导语】本文是一篇说明文，针对人们“难以亲近自然”的想法，介绍了几种亲近自然的独特方式，包括写自然日记、用相机探索自然、园艺和环保志愿活动，鼓励人们尝试这些活动，发现自然的美好。 51．第一段提到“Some people think it’s hard to have a wonderful journey to nature.”，空1后引出“Here are some unusual ways for you.”，需要一个转折句来反驳“很难亲近自然”的观点并过渡到下文方法。选项C“In fact, it’s easy to connect with nature.”（事实上，亲近自然很简单）既回应了前文的“hard”，又自然引出后文的具体方法，逻辑连贯。 52．第二段后文提到“By writing, you can record your experiences in nature... you can also draw what you see in your diary.”，核心是“写日记记录自然”。选项B“Keep a nature diary.”（写自然日记）作为段落主题句，精准概括了本段内容，与后文“writing”“diary”等关键词完全呼应。 53．第三段主题是“用相机探索自然”，空3前为“Explore nature with a camera.”，后文描述了相机的作用。选项E“Taking photos is a great way to be close to nature.”（拍照是亲近自然的好方法）承接了“camera”的话题，解释了用相机亲近自然的意义，与后文内容衔接紧密。 54．第四段围绕“Do gardening.”展开，空4后提到“Helping in a community garden is a great way to learn.”，是给园艺新手的建议。选项D“If you’re new to gardening, you can start small.”（如果你是园艺新手，可以从小处着手）自然过渡到后文的社区花园学习建议，符合“园艺”主题的逻辑递进。 55．第五段主题是“环保志愿活动”，空5前为“You can take part in a clean-up event or a tree-planting activity.”，需要补充更多志愿活动的途径。选项F“You can also search for local environmental groups online.”（你也可以在网上寻找当地环保组织）拓展了志愿活动的参与方式，与前文的志愿活动内容形成补充，逻辑顺畅。 六、 56．natural 57．changeable 58．growing 59．curious 60．than 61．the 62．risk 63．development 64．if 65．recently 【导语】本文主要围绕秋天的叶片物候现象展开，介绍了气候变化对秋天的影响——使秋季时长变长、树叶变色推迟、霜冻延后，同时提出人类可通过控制二氧化碳排放避免最坏影响，普及了气候变化与自然现象的关联。 56．句意：这是一种自然现象。此处需用形容词修饰名词phenomenon（现象），nature是名词，意为“自然”，其形容词形式为natural，意为“自然的”。 57．句意：然而，由于气候变化，秋天正在发生改变。此处需用形容词修饰名词climate（气候），change可作动词或名词，其形容词形式为changeable，意为“易变的”，符合“气候变化”的语境。 58．句意：根据一项研究，季节时长正在变长，这意味着树叶需要更长时间才能改变颜色。此处时态为现在进行时，其结构为“be+动词的现在分词”，grow的现在分词形式为growing。 59．句意：在我自己的社区里，当我发现20年前的树叶比现在落得早得多时，我感到很好奇。系动词feel后接形容词作表语，意为“感到……”，curiosity是名词，意为“好奇”，其形容词形式为curious，意为“好奇的”。 60．句意：在我自己的社区里，当我发现20年前的树叶比现在落得早得多时，我感到很好奇。根据句中的sooner（更早地）可知，此处是两者对比，需用连词than，意为“比”，连接“20年前”和“现在”两个时间节点。 61．句意：气候变化不仅导致树叶变色推迟。此处的leaves（树叶）特指前文提到的“秋天变色的树叶”，表特指时需加定冠词the。 62．句意：这意味着害虫在秋天会活跃更长时间，给人类带来更大的健康风险。greater是形容词，故此处要用名词形式，risky是形容词，意为“有风险的”，其名词形式为risk，意为“风险”，且前面有a修饰，用单数形式即可。 63．句意：然而，我们或许能够避免这种发展。此处需用名词作动词avoid（避免）的宾语，develop是动词，意为“发展”，其名词形式为development，且this后接单数名词。 64．句意：迈克尔说，如果人类控制二氧化碳排放，他们仍然可以阻止气候变化带来的最坏影响。结合语境，此处是条件状语从句，需用连词if引导，意为“如果”，表“控制排放”是“阻止坏影响”的条件。 65．句意：一项新的研究最近表明，在二氧化碳排放达到零之后，变暖可能会停止。此处需用副词修饰动词shown（表明），recent是形容词，意为“最近的”，其副词形式为recently。 七、A. 66．In Qinghai,China. 67．About 105 square kilometers. 68．Because its views are wonderful./Because of its wonderful views. 69．From July to August./In July and August. 70．To deal with altitude sickness. B.71．Dear Peter, I’m glad to hear that you are coming to China. Would you like to visit Huizhou? Huizhou is one of the most popular cities in Guangdong. Let me tell you why it is so attractive. Firstly, there are a lot of places of interest in Huizhou, such as West Lake, Luofu Mountain and so on. Each of them has its own beauty. Secondly, the weather is nice and the scenery is beautiful. You can choose to take a boat on the lake or relax in the mountains with fresh air around. Thirdly, the food is delicious. I strongly suggest you have a taste of the local Hakka dishes which are my favourite. To get to Huizhou, you can take a high⁃speed train or a coach from Guangzhou or Shenzhen. Remember to wear a pair of comfortable shoes, because we may walk a lot. I’m looking forward to your coming.
