Unit 7 The natural world
A Daniel is reading an article about Zhalong Nature Reserve. Read with him and answer the questions below.
Zhalong Nature Reserve is in Heilongjiang Province in the north-east /n θ 'i st/ of China. It is one of the world‘s most important wetlands. The area provides food and cover /'k v (r)/ for a lot of wildlife. It is home to some rare /re (r)/
birds. For example, about 40% of red-crowned /red 'kra nd kre nz/ 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/'de ta m/, so you can easily watch them there.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
~~~~~~~~
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”。
Some people want to make the wetlands smaller in order to have more space for farms and buildings. This will lead/li d/ 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.
~~

从教材习题B2中学中考解题策略
听力预判法
听力预判强调在听力开始之前，根据已有的信息（如题目主题、题型、选项内容等）对听力材料的内容以及可能涉及的要点进行预先判断。在做本题时，先快速浏览，明确主题（如本题主题为保护湿地）及题型（笔记填空），了解需记录信息的范畴（问题、措施等），构建整体框架。
B3 Daniel is writing an article about plete it below with the information in Parts B1 and B2.
Save the wetlands!
Wetlands are really important for wildlife, so we must (1) _________ our wetlands.
Governments can do this by creating /kri 'e t / laws to stop people from (2) _________ on wetlands, to reduce the number of tourists visiting them and to make sure visitors (3) _________ while they are there.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
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。
The Chinese government created Yancheng Nature Reserve. It is a really important wetland and is home to many different plants and rare (4) _________. About 1,000 red-crowned (5) _________ fly to Yancheng every year to spend the winter there!
Local communities can also help protect wetlands. They can set up (6) _________ to help keep the wetlands free from pollution, make sure the tourists are (7) _________ when they visit and plant wetland trees to keep the (8) _________ balanced /'b l nst/.
C Daniel and Amy are talking about what they can do to help protect forests. Work in pairs and talk about the topic. Use the conversation below as a model.
Amy: What can we do to help protect forests, Daniel
Daniel: Well, we should not throw rubbish in forests. We can also work with a clean-up project/'pr d ekt/.
Amy: That‘s a good idea. Rubbish causes pollution and damages the ecosystem in forests.
Daniel: That’s true. And maybe we can take our own chopsticks when eating out.
Amy: Yes. 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/'n l d / are useful tools to help keep forests safe.
Daniel: I agree.
~~~~~~~~~~~~~~
encourage sb. to do sth.
鼓励某人做某事
TIP
"You said it!" is a common way to express agreement.
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.
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
·Wastewater /'we stw t (r)/ from factories and homes
Please help protect the ocean
What we can do
·Clean up the beach
·Use environment-friendly / nva r nm nt 'frendli/
products
·Tell people how to protect the ocean
Call to action ·Volunteer to help
~~~~~~~~~
volunteer to do sth. 自愿做某事
D2 Read Amy‘s proposal on protecting the ocean.
Dear Sir/s (r)/ or Madam /'m d m/,
I am writing today to ask for your help in protecting the ocean.
Introduction:
Say why you are writing the proposal.
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 the biggest problem. There are millions of tons of plastic waste in the ocean. Also, wastewater from houses and factories travels to the ocean and causes pollution. This will harm or even kill/k l/ sea life.
Main
body:
~~~~~~~~
offer sb. sth. =offer sth. to sb.给某人提供某物
~~~~~~~~~
~~~~
介词短语作后置定语，修饰wastewater.
We can help solve /s lv/ 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.
Main body:
· Say why the ecosystem is important.
· State the problems it faces and how people can help.
~~~~~
~~~~~~~~~
~~~~~~~~~
~~~~~
长难句分析：这是一个祈使句。以动词原形State开头，the problems是宾语，it faces 是定语从句，修饰problems，由and连接的how people can help是宾语从句，与the problems同作State的宾语。
It is meaningful to join an environmental / nva r n'mentl/ group and work as a volunteer. Please join us. Together we can help protect the ocean.
Yours sincerely,
Zhao Min
Conclusion:
Encourage people to take action.
从教材语篇D2学写作技巧
承上启下
承上启下是指在文章中，通过特定的语句或段落，将上文的内容与下文的内容连接起来，使文章前后呼应，形成一个有机的整体。如作者通过“However, the ocean is facing many problems.”这一转折句实现承上启下，使文章从积极方面的描述平稳过渡到消极现状的呈现，增强了文章的连贯性，让读者能够顺畅地跟上作者的思路。
TIP
We often end a proposal with a strong and moving sentence to encourage the reader to take action.

· It’s not very easy to study English well.

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。
