①Do you believe that trees can speak For a long time, people thought trees were quiet and lonely, just standing in forests year after year. In fact, there is a busy world that we can’t see under the ground. It is home to roots, fungi (真菌), and many little living things. In this secret world, trees can “talk”, “help” and even “remember” in their own ways.
②When insects (昆虫) eat a tree’s leaves, the tree gives out a kind of smell. The smell is like a warning (警告) message to tell other plants, “Be careful!” Nearby trees “hear” it and produce something to make their leaves taste bad. In this way, they protect themselves before the insects come.
③Trees also have their own “Internet” like humans. Under the ground, fungi and roots connect many trees together. This is called Wood Wide Web. Through it, trees can share food and water. A big, strong tree can help smaller or younger ones when they don’t get enough sunlight or water.
④Trees are not only helpful but also clever. They can even remember things. During a dry season, they close small holes in their leaves to keep water. When rain comes back, they still grow slowly because they remember the dry time.
⑤Forests mean a lot to the Earth. When you walk in a forest, look around and listen carefully. The trees may be quiet, but their silent world has so much friendship and teamwork.
36．What is the main idea of the first paragraph
A．Trees live a quiet life in the forest. B．Fungi help trees share food and water.
C．Trees are home to many small living things. D．Trees have a secret and busy life underground.

A． B． C． D．
40．What is the best title of the passage
A．The Secret Lives of Trees. B．The Importance of Forests.
C．The Silent Growth of Plants. D．The Magic World of Insects.
C
Why do the leaves (叶子) on trees have different colors What makes them change (改变) color
Leaves use sunlight, water, and air to make food for the trees. This way of making food is photosynthesis (光合作用). Photosynthesis is important to animals and plants.
Summer is playtime. But for the leaves of many trees, it’s work, work, work! The sun is shining. The leaves are making food for the trees. The trees keep much food for winter. Leaves are green in summer because they are making food. Leaves also have orange, yellow, or brown colors inside them. During summer, those colors change to green colors.
Many places get cold in autumn with short days and long nights. Trees can’t get much sunlight, so photosynthesis slows down (放慢). Over time (逐渐地), leaves stop making the green chemical (化学物质). And the orange, yellow, and brown colors grow.
When it gets very cold, trees drop (落下) their leaves. They do this to keep themselves safe (安全的). If the leaves freeze (结冰) when they are on the trees, the trees can be hurt (受伤的). So many trees have no leaves in winter. They use the food they keep in summer to get through the cold days and nights.
Spring comes before long. Snow leaves and the rain comes. The sun shines, and new leaves grow from trees. The leaves use sunlight, water, and air to make food. The cycle (循环) begins again.
41．What is photosynthesis according to the text
A．It is a way of growing leaves. B．It is a way of changing colors.
C．It is a way to make food for plants. D．It is a way for animals to eat plants.
42．Why are leaves green in summer
A．Because trees are making food for leaves.
B．Because summer is playtime for the leaves of many trees.
C．Because there are no other colors in leaves in summer.
D．Because leaves are busy making food for trees.
43．What stops leaves from (阻止) making the green chemical in autumn
A．Less (更少的) air. B．Less sunlight. C．Less water. D．Less time.
44．What does the underlined word “They” refer to (指的是)？
A．The trees. B．The leaves. C．The colors. D．The animals.
45．What could be the best title (标题) of the text
A．The Importance of the Sunlight B．The Trees Make Food for Leaves
C．The Colors of the Tree Leaves D．The Changes of the Four Seasons

5．A
【解析】句意：空闲时，比起咖啡，他更喜欢茶。
prefers更喜欢；connects连接；chats聊天；sends发送。根据空格后“tea to coffee”可知，在茶和咖啡之间进行比较，表示更喜欢茶；固定结构“prefer A to B”意为“比起B更喜欢A”，prefers符合语境。

10．B
【解析】句意：我的父亲是一名艺术家，他喜欢在院子里种玫瑰。
husband丈夫；artist艺术家；oxygen氧气；workshop车间。空格前冠词为an，说明单词以元音音素开头，四个单词中artist符合该发音规则，且结合后半句“growing roses”养花的爱好，艺术家符合语境，其余单词语义、语法均不匹配句子。故选B。
11．A
【解析】句意：树木产生氧气，所以人类可以呼吸新鲜空气。
humans人类；workshops车间；seeds种子；quarters四分之一。根据“Trees produce oxygen”以及“breathe fresh air”可知，能呼吸新鲜空气的是人类。

【导语】本文讲述作者在科学课上种植并观察植物，学到了生长知识及照顾植物的重要性，最后表达了对科学课的喜爱之情。
【解析】16．句意：一天在科学课上，她让我们做一件有趣的事。
根据“interesting”以元音音素开头，可知泛指一件有趣的事，应用不定冠词an。a用于辅音音素前，the表特指，均不符合语境。
17．句意：她说我们将学习关于植物的知识。
根据下文“grow a plant”可知，课程内容是学习关于plants“植物”。而非foods“食物”、sports“运动”或birds“鸟类”。
18．句意：我们每个人都需要种植一株植物并在这一个月期间观察它。
根据“Every one of us”作主语谓语用单数，且语境为任务要求，可知 needs。need to do sth.表示“需要做某事”；asks“询问”、waits“等待”、keeps“保持”，语义不通顺。
19．句意：我很喜欢番茄，所以在家的盒子里种了一小棵番茄苗。
根据后半句“so I grow a small tomato plant”可知，作者love“喜欢”西红柿才会去种植。get“得到”、make“制作”、say“说”均不符合逻辑。
20．句意：我把它放在窗边的书桌上。
根据“desk”，植物放在桌面上用on。固定搭配on my desk，表示“在书桌上面”；with“和…… 一起”、from“来自”、about“关于”，搭配错误。
21．句意：我每天给它浇水，细心观察它。
watch it与上文“watch it over a month”相呼应，表示观察植物生长。thank“感谢”、spell“拼写”、circle“圈出”均不符合语境。
22．句意：一周过后，我看见了小小的新芽。
根据“sprout”，可知是视觉观察到的结果。see表示“看见”，符合观察到新芽生长的语境。tell“告诉”、want“想要”、clean“打扫”均不符合句意。
23．句意：随着日子一天天过去，我的番茄植株长高了。
gets tall表示“长高"，符合植物生长的描述。hot“热的”、old“老的”、well“好”，均不符合语境。
24．句意：我了解到阳光和水对植物生长非常重要。
根据主语“sun and water”是复数，可知be动词选用are；am主语只能为I，is搭配单数主语，be不能直接单独作谓语。
25．句意：我还学到，植物生长需要时间，我们要好好照料它们。
前文学到阳光、水的重要性，本句补充另一个知识点，also表示“也，还”；often“经常”、always“总是”、now“现在”，逻辑不符。
26．句意：在学校吃午饭时，我经常和朋友们讨论我们种的植物。
根据学校语境及“talk about”，可知是朋友。children“孩子”、sisters“姐妹”、teachers“老师”均不如friends贴切。
27．句意：我们展示植物的照片，交流如何照料它们，并互相求助。
them指代上文的plants，作look after的宾语。it指代单数，him指代男性，us指代我们，均不符合。
28．句意：四周后，每个学生都带着他们的植物到学校给全班展示。
根据前文“over a month”，可知约四周。days“天”时间太短，months“月”和years“年”与上文“over a month”不符。
29．句意：李老师对我们的成果十分满意。
根据展示成果，老师通常满意，可知 happy。be happy with表示“对……感到满意”，符合语境。quiet“安静的”、right“正确的”、clever“聪明的”均不与with构成此含义的搭配。
30．句意：她让我们继续学习科学相关知识。
根据“Ms Lee is our science teacher”，可知是科学。PE“体育”、math“数学”、English“英语”均与本文主题不符。
31．D 32．B 33．B 34．A 35．C
【导语】本文介绍了树木对人类、野生动物的多重价值，讲述树木可以供给食物、新鲜空气、为动物提供栖息地，还有制作生活用品、降温等实用作用，最后提及植树节，呼吁大家爱护树木。
【解析】31．第二段提到：“People need trees to live.”，树提供食物和新鲜空气，如果没有清洁空气人会生病。整段主要阐述了树对人类生存的重要性。
32．第三段：“Trees are home to many wild animals.”和“They eat the fruit from the trees.”，动物从树上获得家园和食物。
33．根据第四段中“In summer, trees keep us cool.”这一直接信息可知，树木在夏天的作用是降温。
34．文章最后一段提到设立植树节是为了“protect trees”，并以“Let’s take care of trees together!”结尾，旨在呼吁大家保护树木。
35．整篇文章围绕树木、动物、自然环境以及保护自然展开，属于自然主题。C选项“Unit 3 Wonderful Nature”最符合文章主旨。
36．D 37．A 38．D 39．C 40．A
【导语】本文是说明文，介绍树木在地下拥有隐秘的生存网络，它们能够互通警报、共享资源、留存记忆，展示树木不为人知的秘密生存方式。
【解析】36．原文第一段提到“In fact, there is a busy world that we can’t see under the ground…trees can “talk”, “help” and even “remember” in their own ways.”，第一段引出树木地下有一个隐秘且繁忙的世界。
37．原文第二段提到“the tree gives out a kind of smell. The smell is like a warning message…Nearby trees “hear” it，可知树木通过释放气味传递警告。
38．原文第三段提到“Under the ground, fungi and roots connect many trees together. This is called Wood Wide Web.”，说明了“Wood Wide Web”指地下树根与真菌搭建起来的树木之间的连接网络。
39．文章结构分析：①总起段：树木地下有隐秘世界；②③④分述：树木传递警报、地下互联网络、拥有记忆；⑤总结段：森林对地球意义重大。 结构：总——分——总（①总；②③④分；⑤总），对应图示C。
40．全文介绍树木不为人知的交流、互助、记忆等秘密生活。A项“树木的秘密生活”符合。
41．C 42．D 43．B 44．A 45．C
【导语】本文介绍树叶四季色彩变化的原理：夏季树叶通过光合作用产生绿色物质，呈现绿色；秋季光照减少，光合作用放缓，绿色物质停止生成，叶片原本的色彩显现；寒冬树木落叶自保，等到春天新叶长出，新一轮生长循环再次开启。
【解析】41．根据第二段“Leaves use sunlight, water, and air to make food for the trees. This way of making food is photosynthesis”可知，树叶为树木制造养分的方式就是光合作用。
42．根据第三段“But for the leaves of many trees, it’s work, work, work!”和“Leaves are green in summer because they are making food.”可知，夏天树叶变成绿色是因为树叶在夏天忙于给树提供养分。
43．根据第四段“Trees can’t get much sunlight, so photosynthesis slows down. Over time, leaves stop making the green chemical”可知，秋天光照变少，树叶停止生成绿色物质。
44．根据第五段前文“When it gets very cold, trees drop their leaves.”和后文“If the leaves freeze…have no leaves in winter. ”可知，秋天树叶落下是为了保护树，此处的“They”指代的是前文提到的树。
45．全文通篇解释树叶在四季变换颜色的原理，选项C“The Colors of the Tree Leaves”（树叶的色彩）是最佳标题。
46．
natural
【解析】句意：许多游客来到紫金山欣赏其自然美景和丰富文化。空格后“beauty”为名词，此处需用形容词修饰名词作定语，应填natural。
47．flowers

49．is changing
【解析】句意：春天伴随着植物生长，万物都在发生变化。主语Everything为不定代词，作主语时谓语动词用单数；此处用现在进行时is changing，着重强调春天万物正处在持续变化的过程中，贴合春天植物不断生长、景物动态变化的语境。
50．produce

51．information
【解析】句意：你可以在网上搜索更多信息。中文提示词为“信息”，对应单词information；information是不可数名词，无复数变化，单词前的more可直接修饰不可数名词，放在search for后作宾语，符合句子语法和语义。故填information。
52．weight

【解析】原句中“将会举办”是关键词，表示“举办”的动词短语是put on。本句为一般将来时，结构为will+动词原形，后接动词原形put。
59．leave message
【解析】固定短语leave a message表示留口信，I’ll是I will的缩写，will后要使用动词原形，因此填leave； 冠词a后接可数名词单数，口信对应的英文单词是message。
60．
walk
around
【解析】原句中文“四处走动”是关键词，表示“四处走动”的常用短语是walk around。空前有情态动词“will”，因此walk需保持原形，空处分别填walk；around。
61．looking 62．thousands 63．lived 64．peaceful 65．hunted 66．ate 67．died 68．museums 69．is 70．them
【导语】本文以渡渡鸟的第一人称拟人化视角，讲述了渡渡鸟从大量存活到因人类活动灭绝的过程，呼吁人类保护现存野生动物。
【解析】61．句意：你在看我吗？本句是现在进行时的一般疑问句，结构为Are +主语+现在分词+其他，因此动词look要变为现在分词形式looking。
62．句意：实际上，曾经真的有成千上万只我们渡渡鸟存活在地球上。固定搭配thousands of表示“成千上万的”，描述概数时，thousand要用复数形式thousands。
63．句意：我们曾经生活在印度洋的一座小岛上。渡渡鸟生活在印度洋岛屿是历史事件，全文描述渡渡鸟历史用一般过去时，因此live变为过去式lived。
64．句意：那是多么平静安稳的生活啊！空格处需要形容词和后文的“safe”并列，共同修饰名词“life”，名词peace的形容词形式是peaceful，意为“平静安宁的”。
65．句意：因为我们行动缓慢又不会飞，他们就大肆捕猎我们。人类捕猎渡渡鸟是过去发生的动作，用一般过去时，hunt的过去式为hunted。
66．句意：此外，他们带来的猪、猫和狗还会吃我们的蛋。人类带来的动物偷吃渡渡鸟的蛋是过去发生的动作，用一般过去时，eat的过去式为ate。
67．句意：最终，我们很快就灭绝了。渡渡鸟灭绝是过去已经发生的结果，用一般过去时，die的过去式为died，die out是固定搭配，意为“灭绝”。
68．句意：所以如今，我们只能被陈列在全世界的博物馆里。根据后文“around the world”可知，渡渡鸟标本陈列在全球多个博物馆，因此用名词复数形式museums。
69．句意：世界充满了奇妙的动物。“世界上充满奇妙的动物”是客观事实，用一般现在时，主语“The world”是第三人称单数，因此be动词用is。
70．句意：请尽你们最大的努力去保护它们。动词“help”后接人称代词宾格作宾语，主格they的宾格形式是them。
71．例文
