Read with him and answer the questions below. Zhalong Nature Reserve is in Heilongjiang Province in the north-east of China. It is one of the world’s most important wetlands. The area provides food and cover for a lot of wildlife. It is home to some rare birds. For example, about 20% of red-crowned cranes live in Zhalong. Many birds live in Zhalong all year round, while some go there only for a short stay. Most birds are active in the daytime, so you can easily watch them there. Some people want to make the wetlands smaller in order to have more space for farms and buildings. This will lead to less space for wildlife. Moreover, if fishermen keep fishing there, the birds will not have enough food to eat. Now the Chinese government has made laws to prevent all these things in Zhalong. Reading 新课讲授 23021 1 Why is Zhalong an important place for the birds? Because it provides food and cover for them. It’s also home to some rare birds. Many birds live there all year round and it’s easy to watch them in the daytime. 2 What other actions can we take to help protect wetlands? We can plant more trees around the wetlands. We can also educate more people about the importance of wetlands and ask them not to litter there. 23021 1. The area provides food and cover for a lot of wildlife. cover 是个兼义词，主要意思有： (1)名词，躲避处，指提供掩护或保护的地方； (2)名词，封面、封皮，指书籍、杂志等的封面； (3)名词，罩子、套子，指容器的上盖等； (4)动词，遮盖；覆盖，指用某物覆盖或隐藏另一物体； (5)动词，掩盖；遮掩，表示隐藏或掩饰某种情况。 be covered with 被……覆盖 Language points 23021 e.g. Grass provides cover for small animals, like rabbits. 草为小动物如兔子提供躲避处。 The book has a beautiful cover. 这本书有漂亮的封面。 He bought a cover for his old pot. 他为他的旧锅买了一个盖子。 Don’t cover your face when you are sleeping. 睡觉时不要把你的脸蒙上。 He tried to cover his mistakes. 他试图掩盖他的错误。 23021 2. Many birds live in Zhalong all year round, while some go there only for a short stay. 长难句分析：这是一个并列句，由while连接两个并列的句子，表示对比关系，while意为“然而”。 23021 3. Some people want to make the wetlands smaller in order to have more space for farms and buildings. in order to 意为“为了”，用于引导目的状语，后面使用动词原形。在句子中可以放在句首或句中，在句首时要用逗号隔开。其否定形式是in order not to，意为“为了不……”。 in order that 和so that 都和in order to 意思相同，不过它们的后面要使用从句，不能接动词原形。 23021 e.g. We started early in order to catch the first bus. 我们早早出发为了赶上第一班公交车。 She got up quietly in order not to wake up the baby. 她悄悄起床为了不吵醒宝宝。 We started early in order that we could catch the first bus. 我们早早出发以便我们能赶上第一班公交车。 He studied hard so that he could pass the exam. 他努力学习以便能通过考试。 23021 4. This will lead to less space for wildlife. lead 可以作及物动词，意为“引领；带路”，作不及物动词，意为“导致”，表示由于某种原因出现某种不太好的情况。短语 lead to 意思是“导致，造成（后果）”，后常接名词。 lead 的过去式是led。leader 是lead 的名词，意为“领导者”。 e.g. Poor eating habits can lead to health problems. 不良的饮食习惯可能导致健康问题。 He leads the team in the project. 他在这个项目中领导团队。 Who is the leader of your soccer team? 谁是你们足球队的队长？ 23021 5. Moreover, if fishermen keep fishing there, the birds will not have enough food to eat. if fishermen keep fishing there为if引导条件状语从句。 23021 B1 Daniel is listening to a talk about a wetland.

Governments can do this by creating laws to stop people from building on wetlands, to reduce the number of tourists visiting them and to make sure visitors do no harm while they are there. (1) 长难句分析：这是一个主从复合句。主句是Governments can do this, by creating laws是方式状语，后面三个并列的不定式短语“to stop...”、“to reduce...”和“to make sure...”作目的状语，用来进一步说明制定法律的目的。 Language points 23021 (2) create 作动词，意为“创建，创造”，常用作及物动词，后面接名词或名词短语作宾语，表示创造出具体的事物。 create 的形容词形式是creative，意为“有创造性的”。 creativity 是名词，意为“创造力；创造性”，通常用作不可数名词。 e.g. We should create a better future for the children. 我们应当为孩子们创造一个更好的未来。 She created a beautiful painting. 她创作了一幅美丽的画。 She has a very creative mind. 她有一个非常有创意的头脑。 The boy is full of creativity. You never know what he is thinking. 这个男孩很有创造力。你永远不知道他在想什么。 23021 (3) stop sb. from doing sth. 阻止某人干某事 e.g. Nothing can stop me from playing basketball. ‌ 没有什么能阻止我打篮球。 23021 (4) 辨析: a number of 与the number of a number of 意为“许多、大量”，后接复数名词或代词，number 前可用large、small 等词来修饰，表示程度大小。“a number of + 复数名词/ 复数代词”作主语时，谓语动词用复数。 the number of 意为“……的数量”，后接复数名词或代词，强调人或物体的数量。“the number of + 复数名词/ 复数代词”作主语时，谓语动词用单数。 e.g. The number of the students in our class is 40.我们班的学生数量是40. A number of tourists are on the beach. 沙滩上有大量的游客。 23021 2. They can set up volunteer groups to help keep the wetlands free from pollution, ... (1) set up 是一个“动词+ 副词”型短语，名词作宾语通常放在后面，代词it 或them 作宾语要放在两个词的中间。它的意思有： a.建立或创建，表示组建公司、组织、团队等； b.安排或准备，表示对会议、活动等进行先期筹备； c.搭起或搭建，表示简单地搭起舞台、房屋、帐篷等。 e.g. They set up a small company last year. 去年他们成立了一个小公司。 Let’s set up a meeting for the next week. 我们为下周开个会吧。 These are the tents for the camping. Please set them up. 这些是露营的帐篷。请把它们搭起来。 23021 (2) 短语 keep ... free from ... 意思是“保护……免受……伤害（或影响）”。 e.g. Parents always want to keep their kids free from harm. 父母总想保护自己的孩子免受伤害。 23021 Daniel and Amy are talking about what they can do to help protect forest.

We can encourage people to protect forests too. Daniel: You said it! We can show people different ways to save forests. Amy: Yes! Education and knowledge are useful tools to help keep forests safe.

Speaking 23021 D Imagine you are a member of an eco-club. You are going to write a proposal asking people to protect an ecosystem and help solve the problems it faces. Writing 23021 D1 Look at Amy’s outline for her proposal to ask people to help protect the ocean. Please help protect the ocean The importance of the ocean ·Home to many kinds of sea life ·Provides us with food ·Offers us space for fun The problems it faces ·Millions of tons of plastic waste ·Wastewater from factories and homes What we can do ·Clean up the beach ·Use environment-friendly products ·Tell people how to protect the ocean Call to action ·Volunteer to help 23021 Dear Sir or Madam, I am writing today to ask for your help in protecting the ocean. The ocean is home to many kinds of sea life. It provides us with food and offers us space to have fun. However, the ocean is facing many problems. Pollution is one of the biggest problem. There are millions of tons of plastic waste in the ocean. Also, wastewater from factories and houses travels to the ocean and causes pollution. This will harm or even kill sea life. We can help solve the problems. We should keep beaches clean and use more environment-friendly products. It is also a good idea to tell people how to protect the ocean. We can also encourage them to help. It is meaningful to join an environmental group and work as a volunteer. Please join us. Together we can help protect the ocean. Yours sincerely, Zhao Min D2 Read Amy's proposal on protecting the ocean. Read it below and analyse its structure. Introduction: Say why Amy is writing the proposal. Main body: ·Say why the ecosystem is important. ·State the problems it faces and how people can help. Conclusion: Encourage people to take action. 23021 1. It provides us with food and offers us space to have fun. (1) provides sb. with sth.=provide sth. for sb. 为某人提供某物 e.g. The hotel provides guests with free Wi-Fi. =The hotel provides free Wi-Fi for guests. 酒店为客人提供免费Wi-Fi。 (2) offer sb. sth. =offer sth. to sb.给某人提供某物 e.g. He offered me a cup of tea. = He offered a cup of tea to me. 他给我提供了一杯茶。 Language points 23021 2. We can help solve the problems. solve 是及物动词，意为“解决；解答”，通常用于处理问题、谜团、方程等。solve 的同义短语是work out。 solve a problem 解决问题 solve a mystery 解开谜团 solve an equation 解方程 solve a riddle 解开谜语 e.g. She solved the math problem in just a few minutes. 她仅在几分钟内解决了这个数学问题。 I think nobody can solve the mystery. 我认为没有人能解开这个谜团。 Let’s ask our math teacher to solve the equation. 我们去让数学老师解这个方程吧。 I can’t solve the riddle. Can you help me? 我解不开这个谜语。你能帮我吗？ 23021 3. It is meaningful to join an environmental group and work as a volunteer. It’s + adj. + (for sb.) to do sth. 是一种常用结构，意为“（对某人来说）做某事……”. It 是形式主语，真正的主语是后面的动词不定式。因为动词不定式结构稍长，放在句首会让句子显得头重脚轻，故使用形式主语It，而把动词不定式后移。 如果句中的形容词描述的是后面所做事情的特点，要使用介词for；如果形容词描述的是后面人的特点，则使用介词of。 e.g. It’s very kind of you to help us. 你能帮助我们真是太好了。 It’s not very easy to study English well. 学好英语是不太容易的。 It’s impossible for us to finish the work in a week. 对于我们来说一个星期内完成工作是不可能的。 23021 D3 Choose an ecosystem and write a proposal asking people to protect it. Make an outline like the one in Part D1. Use Amy's proposal as a model. Please help protect ... The importance of ... The problems it faces What we can do Call to action 23021 Structure Part 1 Para. 1 Introduction: Say who your best friend is and when and where you met. Part 2 Para. 2-Para . 5 Main body: Describe your best friend’s looks and best qualities. Part 3 Para. 6 Conclusion: Say how you feel about your best friend.
