Scientists studied reports of new behaviours among different kinds of birds around the world.The study includes more than 3,800 new behaviours among 8,600 kinds of birds.They discovered that the more new hunting skills the birds learn, the larger population they will have. However, scientists also found that innovation(革新) can only protect birds from changes in their living places, but not from overhunting or the danger from other animals.For example, some animals are very dangerous to some birds: snakes can eat little birds; some hungry mice steal birds’ eggs.Above all, humans often mean the greatest danger to birds.They always take up too much space, cut down trees and even cause various kinds of pollution. This shows that, unlike what is usually believed, the ability of innovation protects animals from some but not all of the rapid changes in the environment. (　 　)1.According to Paragraph 1, which of the following may not be included in the birds’ changes of behaviours? A.Trying new food. B.Learning new hunting skills. C.Moving to a new place. D.Living with humans. (　 　)2.Which of the following shows the result of the study in Paragraph 2? (　 )3.What can we learn from the text? A.Humans often help birds to change themselves. B.Snakes and mice are the greatest danger to birds. C.Innovation in hunting skills plays a role in birds’ living.

Elephants can weigh up to 7 tons and stand about 3 metres tall. They live in grasslands and forests in Africa and Asia. They mainly eat grass, leaves, and fruit. With proper care, elephants can live up to 70 years, which is almost as long as a human’s lifespan! There are many reasons why I love elephants. First of all, they are highly intelligent and emotional. They can use tools, recognize themselves in mirrors, and even care about sad friends by touching them with their trunks. What's more, elephants have strong family connections. They live in groups led by females, and they care deeply for their babies.  Elephants play an important role in nature. They help forests by spreading seeds through their waste, allowing new plants to grow. They also dig waterholes that other animals use. Sadly, human activities like hunting for ivory and cutting down trees are making them lose their homes. If elephants disappear, ecosystems will suffer. We must protect them. Every effort counts—let's save these fantastic creatures before it's too late!  任务一:用横线画出第二、三段的主题句。 任务二:第二段说明喜爱的理由时,作者给出了　 　个理由,用连接词　 　和　 　引出。  动物是人类亲密的朋友,人类是动物信赖的伙伴。你最喜欢哪种动物呢?假设你校英语社团正在举办以“My Favourite Animal”为题的征文比赛,请你根据以下要点写一篇短文参赛。 要点:1.描述一种你最喜欢的动物;2.说明它和人类的联系;3.呼吁大家爱护动物。 要求:1.作文中不得出现学校的真实名称和学生的真实姓名;2.语句连贯,词数80左右。 My Favourite Animal 　 　   答案： Unit 4　Amazing Plants and Animals 第一课时　Section A(1a—1d+Pronunciation) 一、读单词,找出画线部分发音不同的一项 (　D　)1.A.train　　　　　B.play　　　　 C.plate D.air (　C　)2.A.sky B.light　　　　 C.city D.kite (　A　)3.A.coincide B.noise　　　　 C.point D.enjoy (　B　)4.A.brave B.blood　　　　 C.brand D.brush (　C　)5.A.create B.crowd　　　　 C.ground D.cross 二、根据括号内所给汉语注释或首字母提示写出单词的正确形式(每空一词) 1.The old tree is covered with soft 　moss　(苔藓).  2.The 　redwood　(红杉) tree is a very tall type of tree.  3.A 　cheetah　(猎豹) can run at a very high speed.  4.The elephant is one of the 　heaviest　(重) land animals.  5.The Pacific Ocean is the largest　 ocean on the earth.  三、用所给单词的适当形式填空 1.The fifth orange is 　the biggest　(big) of all.Give it to the young boy, please.  2.The sunset at the beach is 　the most beautiful　(beautiful) scene I’ve ever seen.  3.Among all the students, Tom runs 　the fastest　(fast).  4.The Sahara is 　the largest　(large)desert in the world.  5.The ant is one of 　the smallest　(small) insects.  6.This is 　the shortest　(short) pencil in the box.  7.Mount Qomolangma is 　the tallest　(tall) mountain in the world. 　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　 四、完形填空 Dear Nature Lover, You asked about the world’s most amazing plants and animals.Let me tell you some really cool ones!

Scientists studied reports of new behaviours among different kinds of birds around the world.The study includes more than 3,800 new behaviours among 8,600 kinds of birds.They discovered that the more new hunting skills the birds learn, the larger population they will have. However, scientists also found that innovation(革新) can only protect birds from changes in their living places, but not from overhunting or the danger from other animals.For example, some animals are very dangerous to some birds: snakes can eat little birds; some hungry mice steal birds’ eggs.Above all, humans often mean the greatest danger to birds.They always take up too much space, cut down trees and even cause various kinds of pollution. This shows that, unlike what is usually believed, the ability of innovation protects animals from some but not all of the rapid changes in the environment. (　D　)1.According to Paragraph 1, which of the following may not be included in the birds’ changes of behaviours? A.Trying new food. B.Learning new hunting skills. C.Moving to a new place. D.Living with humans. (　B　)2.Which of the following shows the result of the study in Paragraph 2? (　C　)3.What can we learn from the text? A.Humans often help birds to change themselves. B.Snakes and mice are the greatest danger to birds. C.Innovation in hunting skills plays a role in birds’ living. D.Scientists discovered some new kinds of birds in the world. 六、阅读下面短文,在空白处填入一个适当的词,或填入括号中所给单词的正确形式 There is a nature park in the southwest of our city.The government built it for the rare(稀有的) animals 1.　to live　(live).The nature park is a symbol of our city.  Yesterday, my friends and I 2.　got　(get) up early to visit it.We saw many different 3.　kinds　(kind) of animals, such as tigers, bears and giraffes.The giraffes have 4.　the longest　(long) necks of all the animals in the world.

Elephants can weigh up to 7 tons and stand about 3 metres tall. They live in grasslands and forests in Africa and Asia. They mainly eat grass, leaves, and fruit. With proper care, elephants can live up to 70 years, which is almost as long as a human’s lifespan! There are many reasons why I love elephants. First of all, they are highly intelligent and emotional. They can use tools, recognize themselves in mirrors, and even care about sad friends by touching them with their trunks. What's more, elephants have strong family connections. They live in groups led by females, and they care deeply for their babies.  Elephants play an important role in nature. They help forests by spreading seeds through their waste, allowing new plants to grow. They also dig waterholes that other animals use. Sadly, human activities like hunting for ivory and cutting down trees are making them lose their homes. If elephants disappear, ecosystems will suffer. We must protect them. Every effort counts—let's save these fantastic creatures before it's too late!  任务一:用横线画出第二、三段的主题句。 任务二:第二段说明喜爱的理由时,作者给出了　2　个理由,用连接词　First of all　和　What’s more　引出。  动物是人类亲密的朋友,人类是动物信赖的伙伴。你最喜欢哪种动物呢?假设你校英语社团正在举办以“My Favourite Animal”为题的征文比赛,请你根据以下要点写一篇短文参赛。 要点:1.描述一种你最喜欢的动物;2.说明它和人类的联系;3.呼吁大家爱护动物。 要求:1.作文中不得出现学校的真实名称和学生的真实姓名;2.语句连贯,词数80左右。 标准提分版: My Favourite Animal 　Dogs are my favourite animals. They come in different shapes, sizes and colours. With bright eyes and wagging tails, they always look so lively and friendly.  Dogs have a close connection with humans. They are not only great pets but also help humans in many ways. For example, guide dogs help the blind, and police dogs help catch bad people. They offer love and companionship, making our lives more wonderful.  Dogs are our friends. It is our duty to protect them. Let’s treat them with kindness and build a better world for both humans and dogs.　  进阶优化版: My Favourite Animal 　Dolphins are my favourite animals. Dolphins are really lovely. They have sleek, grey bodies with a curved mouth that always looks like a smile, making them seem friendly. Their dorsal fin helps them swim fast, and they use their flippers to steer in the ocean.  Dolphins are highly intelligent and social. They live in groups called pods, where they play and hunt together. They mainly eat fish and squid. Sometimes, they even swim alongside boats, as if greeting the people on board.  Dolphins play a crucial role in the ocean ecosystem. We should protect them. We can start by reducing ocean pollution and stopping illegal fishing. Let’s work together to make sure these wonderful animals can live safely in their ocean homes.　  学科网（北京）股份有限公司 $
