We live on the same Earth. Animals and people can’t be separated from each other. If there is no animal, we will not live. Animals 1 (success) in making the world colorful. Every animal 2 (have) its place in the balance of nature. If we destroy a kind of animal, we will have many other 3 (problem) very soon. For example, when farmers kill a large number of hawks (鹰), the mice will destroy 4 (farmer) rice. Because hawks eat mice. Without hawks, the number of mice is becoming 5 (large) than before. But many people don’t realize this. Along with the increase of population, they 6 (kill) lots of wild animals for food, money and other things. They also destroy animals’ living environment. It 7 (include) living places and food situations. More and more animals are 8 (danger). Giant pandas, a kind of animals which live in the forests and live on bamboo 9 (leaf), are one of them.

Learning about amazing plants and animals is a popular 1 for many of them. Jane 2 to study rainforest plants with her dad last summer. At first, it was 3 for her to tell different plant species apart. But her dad always 4 her to keep observing. After months of 5 , she can name over 30 kinds of rainforest plants now. She reads about plants to 6 after busy school days. Jack’s hobby is studying wild animals. His uncle takes him to the nature park every weekend. He thinks studying animals helps him 7 about the balance of nature. Lily loves to 8 new facts about unusual plants. She has a notebook full of her findings. She enjoys it 9 these facts 10 not just plant features but also their survival skills. 【答案】1．hobby 2．started 3．difficult 4．encouraged 5．study 6．relax 7．learn 8．discover 9．because 10．include 【导语】本文是一篇说明文，主要讲述了几名学生探索自然的爱好、过程及收获。 【详解】1．句意：了解奇妙的动植物是他们许多人喜爱的一种爱好。此处需要一个名词，在句中表示“爱好”的核心语义。因为前文提到学生们有自己探索自然的方式，且空格前有不定冠词a和形容词popular修饰，所给单词中hobby符合语境，故填hobby。 2．句意：去年夏天，简开始和她爸爸一起研究雨林植物。此处需要一个动词的过去式，在句中表示“开始”的核心语义。因为句末有明确的过去时间状语last summer，句子时态应为一般过去时，且start to do sth.为固定搭配，意为“开始做某事”，所给单词start需变为started，符合语境，故填started。 3．句意：起初，对她来说区分不同的植物物种是很困难的。此处需要一个形容词，在句中表示“困难的”的核心语义。因为It is + adj. + for sb. + to do sth.为固定句型，意为“对某人来说做某事是……的”，结合At first（起初）和区分不同物种的实际情况，可知这并不容易，所给单词difficult符合语境，故填difficult。 4．句意：但她的爸爸总是鼓励她继续观察。此处需要一个动词的过去式，在句中表示“鼓励”的核心语义。因为encourage sb. to do sth.是固定搭配，意为“鼓励某人做某事”，且承接上文的过去时态，所给单词encourage需变为encouraged，符合语境，故填encouraged。 5．句意：经过几个月的研究，她现在能说出30多种雨林植物的名字了。此处需要一个名词，在句中表示“学习，研究”的核心语义。因为位于介词of 之后，需要接名词作宾语，所给单词study本身即可作不可数名词，直接使用其名词原形构成“months of study”符合语法与语境，故填study。 6．句意：在忙碌的上学日之后，她通过阅读关于植物的书籍来放松。此处需要一个动词原形，在句中表示“放松”的核心语义。因为此处to为不定式符号，表目的，后接动词原形，阅读植物书籍是她在忙碌学习后的一种放松方式，所给单词relax符合语境，故填relax。 7．句意：他认为研究动物有助于他了解大自然的平衡。此处需要一个动词原形，在句中表示“学习，了解”的核心语义。因为help sb. (to) do sth. 为固定搭配，意为“帮助某人做某事”，这里省略了to，需用动词原形，learn about意为“了解/学习关于……”，所给单词learn符合语境，故填learn。 8．句意：莉莉喜欢发现关于奇特植物的新事实。此处需要一个动词原形，在句中表示“发现”的核心语义。因为love to do sth.意为“喜欢做某事”，to后接动词原形，结合宾语new facts（新事实）以及后文的findings（发现），所给单词discover符合语境，故填discover。 9．句意：她很享受这个过程，因为这些事实不仅包括植物的特征，还包括它们的生存技能。此处需要一个连词，在句中表示“因为”的核心语义。因为前后两个分句之间是因果关系，后半句解释了她享受这件事的原因，所给单词because符合语境，故填because。 10．句意：她很享受这个过程，因为这些事实不仅包括植物的特征，还包括它们的生存技能。此处需要一个动词，在句中表示“包括，包含”的核心语义。因为引导的原因状语从句缺少谓语动词，主语these facts为复数，且描述的是客观事实，时态为一般现在时，所给单词include需保持原形，符合语境，故填include。 九．阅读表达 Polar bears are the largest meat-eating animals on land, and they are the largest of all bears. They live in the cold Arctic. They are powerful swimmers who hunt seals (海豹) in the water. Polar bears can run 40 kilometres per hour. Polar bears live in the icy Arctic areas of Alaska, Canada, Greenland, Norway and Russia. They spend much of their time swimming in the cold seas. Polar bears are up to 10 feet long and weigh about 1,700 pounds. Polar bears have small heads, powerful jaws and black noses. They have a strong sense of smell. They have 42 teeth and the tail is small and flat. They have wide front paws. There are small webs on their toes that help them swim. These bears swim with their front feet and steer (掌舵) with the hind feet. Polar bears have two types of fur. They have thick, woolly fur close to the skin. Their fur keeps them warm. They also have hollow (中空的) guard hairs. These hairs keep them from getting wet. Their white-looking coats camouflage (伪装) them well in the snow and ice. Under the fur, polar bears have black skin. They also have a thick layer of fat under the skin that helps keep them warm. Polar bears are meat-eaters. They often hunt for food in the water, often many miles from land. They eat mostly seals. A polar bear’s stomach can hold up to 150 pounds. 1．What do polar bears like having as their food? 2．Who has fewer teeth, polar bears or human beings? 3．How many kinds of fur do polar bears’ bodies have? 4．What can help keep polar bears warm? 5．What words can describe polar bears? What other animals do you think are similar to them? 【答案】1．Seals. 2．Human beings. 3．Two. 4．Their fur and a thick layer of fat under their skin. 5．Amazing, powerful and strong. I think whales are similar to them because they are all strong. (答案不唯一, 合理即可) 【导语】本文是一篇说明文，主要介绍了北极熊的生存环境、外貌特征、身体构造以及生活习性。 【详解】1．文章最后一段“Polar bears are meat‑eaters…They eat mostly seals.”。这是原文直接给出的食物信息，直接提取作答。 2．文章第三段“They have 42 teeth”。可推知北极熊牙齿数量较多，结合常识，人类通常有28到32颗牙齿。因此，人类的牙齿比北极熊少。 3．文章第四段开头“Polar bears have two types of fur.”，原文直接点明毛发种类数量，直接提取该信息。 4．文中两处说明保暖要素：一是“Their fur keeps them warm.”；二是“They also have a thick layer of fat under the skin that helps keep them warm.”，把两点信息整合即可。 5．本题属于开放性试题，答案不唯一。描述词需要基于原文事实，相似动物言之有理即可。可以结合体型、生存环境、食肉特点进行作答。 十．写作 某英文网站正在开展以“植物的力量”为主题的征文活动。假设你是李华,请你用英文写一篇短文投稿,介绍一种植物,并说说你为什么要选择这种植物。 提示问题: (1)What is its name?　　     (2)Where does it grow? (3)Why did you choose it? (4)What are some interesting facts about it? 要求:1.词数80以上;2.开头已给出,不计入总词数;3.文中不得出现真实姓名、校名等信息。 The Power of Plants 【答案】 The Power of Plants Plants are very important to us. They provide food, medicine, and beauty. Today, I want to introduce one of the most resilient plants I know—bamboo. Bamboo is truly a marvel of nature. It grows in many parts of Asia, particularly in mountainous areas. While other plants require specific conditions to survive, bamboo thrives as an incredibly strong and adaptable plant. I chose bamboo because it is one of the fastest-growing plants on Earth. Some bamboo can grow over 90 centimeters in just a single day! This rapid growth is not just fascinating but also highly beneficial. Moreover, it can be used to make furniture, paper, and even clothing. An interesting fact is that bamboo can also purify the air. Let's protect plants like bamboo. They are not only useful but also demonstrate the power of nature. Every plant deserves our care and respect. 1 学科网（北京）股份有限公司 学科网（北京）股份有限公司 $ Unit 4 Amazing Plants and Animals 基础训练（单词、短语、句子、语法、写作） 一、根据中文提示完成句子 1.A big bird will ________ (出现) in the sky soon. 2.How much does this elephant ________ (重)? 3.I ________ (相信) that we can finish the work on time. 4.There is green ________ (苔藓) on the old stone. 5.The tall ________ (红杉) grows in the west of China. 6.The ________ (猎豹) can run very fast. 7.________ (竹子) is the main food of pandas. 8.We should learn the ________ (美德) of hard‑working. 9.This is a useful ________ (工具) for gardeners. 10.The red ________ (玫瑰) stands for love. 11.The ________ (牡丹) is a beautiful Chinese flower. 12.The ________ (莲花) grows in the water. 13.The ________ (蝴蝶) has colourful ________ (翅膀). 14.The little ________ (青蛙) jumps into the river. 15.________ (银杏) is an old kind of tree. 二、首字母填空 1.We should c________ the two ideas together. 2.I can’t i________ life without animals. 3.Animals can c________ with each other in different ways. 4.We must p________ our natural environment. 5.The bad news will d________ him. 6.Bees make sweet h________. 7.There is a close c________ between plants and animals. 8.We need to take a________ to help them. 9.The earth is a special p________. 10.The e________ keeps nature balanced. 11.We know the i________ of protecting wildlife. 12.What’s the t________ of this article? 13.The small a________ is carrying food home. 14.Money can’t bring us true h________. 15.We can see many m________ in the forest. 三、用所给词的正确形式填空 1.This is a ________ (fold) bike. 2.This kind of flower is very ________ (popularity). 3.He is ________ (actual) a hard‑working student. 4.The ________ (shoot) of the plant is growing fast. 5.The plane will ________ (land) in ten minutes. 6.He is from Africa.
