For a long time we have learned about the 3Rs, but now there are two more in the mix.5Rs are Refuse, Reduce, Reuse, Repurpose, Recycle, in that order.The order of the Rs is also important.The closer to the start of the list, the more important it is.Let’s start from our lifestyles!
Refuse
Our lives are full of things we don’t need, and each of them has an environmental cost.Think it over when buying.Just deciding not to spend $100 on things our family doesn’t want can save 100 kg greenhouse gas pollution!

Repurpose
Simply take something you are no longer using and change it for another more practical use.Think, help your children use old newspapers for art projects.
Recycle
To recycle is to make new things from old things.In our home, anything made from metal, wood, paper and most plastics is possible to be recycled.

A
Waste sorting (分类) is important.It is environment-friendly and helps to save resources.Now, more and more Chinese people are starting to sort out the rubbish before throwing it away.We are glad to see some fine examples.
However, it is not easy for everyone to do this.Some people may spend so much time deciding the kind of their rubbish.Luckily, twin sisters Chu Siyu and Chu Siqi from Beijing Huiwen No.1 Primary School developed an app to help solve the problem.
The app is easy to use.When users need to throw away their rubbish, they open the app first.In the app, they can find the names of different rubbish.Then, they choose a kind of rubbish in the app, and the right rubbish bin will open.This not only helps users to do waste sorting quickly but also allows them to throw away their rubbish without touching the bin.It is more sanitary (卫生的).
The app also makes use of speech recognition (语音识别) technology.With the help of this technology, users can just speak out the name of the rubbish, and then the rubbish bin will open.How helpful!
Waste sorting isn’t really difficult, and we just need time to get familiar with it.Of course, technology can help us to do it better.If we can do it together, we can help save our planet.
(B)1.According to the passage, waste sorting _______.
A.can help us save money
B.is friendly to environment
C.is getting popular in Africa
(C)2.If users want to use the app, they need to _______first before they throw away their rubbish.
A.speak out the name of the rubbish
B.choose a kind of rubbish
C.open the app
(A)3.According to the passage, what are the features of the app
①Do waste sorting quickly.
②Easy to use.
③Need to touch the rubbish bin.
A.①② B.①③ C.②③
(A)4.We might see this passage from _______.
A.a magazine B.an ad C.a storybook
(B)5.What is the structure of the passage
B
(2023·湘潭中考)
People are getting more worried about the effect (影响) of fast fashion on the environment.
Fast fashion is making clothes in large numbers at a low price.Factories make 100 billion (十亿) pieces of clothing every year.The fast fashion business is doing great harm to the environment.Many of the clothes end up in rubbish bins and are not recycled.A French scientist wrote: “Every year in Europe, four million tons of clothing ends up in the rubbish.Less than 1% of this is recycled.” Another bad effect on the environment is caused by the chemicals (化学物品) used to make clothes.These also cause health problems for people working in clothes factories.
The way people buy clothes is making the problem of clothing waste worse.Many years ago, people went to stores and tried clothes on.They spent more time and thought more carefully before buying clothes.They also wore them for longer.Today, people order cheap clothes online.And if they don’t like them, they send them back.Some people buy clothes and never ever wear them.This is leading to a throw-away society.
So next time before you buy new clothes, think carefully if you truly need them.If not, don’t buy them! Your action will make a difference to the environment.
(B)6.Fast fashion is making _______in large numbers at a low price.
A.rubbish B.clothes C.books
(A)7.The French scientist wrote that _______of the clothing was recycled.
A.less than 1% B.more than 10% C.about 20%
(A)8.What’s the main idea of Paragraph 3
A.The way of buying clothes causes a worse clothing waste problem.
B.Some people nowadays like to order their clothes on the Internet.
C.Some people like to buy lots of clothes but never ever wear them.
(C)9.Which part of a magazine can we read the text from
A.Culture. B.Health. C.Environment.
三、任务型阅读
Wind power is a very clean source of energy.This is how wind power works.Wind makes windmills spin (旋转).When the windmills spin,they make electricity.Then we can use the electricity.
A lot of people think that wind power is new,but that’s not true.For thousands of years,people have used wind to sail boats and move water.We still do those things today,but these days we mostly use wind power to make electricity.
Wind power is a very popular source of energy.Most people think that we should use it more and more.First of all,it’s clean.Windmills don’t pollute the environment at all.Second,we can use wind power forever.After all,we will always have wind.Also,wind power is cheap,and it’s getting even cheaper.
A lot of people don’t understand wind power very well.They believe that there are problems with wind power,but many of those problems are not real.For example,some people say that windmills are dangerous for birds.That used to be true,but it isn’t true anymore.Old windmills killed birds because they spun very fast.New windmills spin slowly,and they aren’t dangerous for birds.
However,there are real problems with windmills.One problem is that many people think windmills are very ugly.This is a problem for some people because windmills are often in very pretty areas.Also,wind doesn’t blow all the time,so we can’t use wind power all the time.Finally,windmills are noisy.
Wind power is becoming more and more common.Right now,more than 80 countries use wind power.About 2.5 percent of the world’s power comes from the wind.For some countries,that number is a lot higher.Wind power gives Denmark more than 25 percent of its electricity.
1.Wind power can be turned into electricity when windmills spin.
2.People have used wind to sail boats and move water for a long time.
3.New windmills don’t hurt birds because they spin at a slow speed.
4.One of the real problems with windmills is that they are very ugly.
5.Do you think wind power can be used the most popularly in the world Why or why not
(答案不唯一,根据文本言之有理即可。)
教学总结与教学反思
1.本单元教学,授课教师与时俱进,努力挖掘学生的现实生活资源,积极以学生的视角来关注社会生活,尤其是学生所关注的热点话题,选取学生很喜欢的并津津乐道的歌星的视频引出本单元教学的话题:环境污染,激发了学生对本章节的学习兴趣。
2.图片展示贴近生活,引起学生共鸣。在导入环节中展示不同污染类型的图片,贴近学生的生活,学生用英语描述起来比较容易,提高了学生的积极性。之后展示“破碎的地球”和污染给人类带来的危害,带给学生视觉上的冲击和强大的震撼力,深深触动学生,使学生获得印象深刻的感性认识,从而引起学生思想上的共鸣,于是就更加坚定了“保护环境,从我做起”的信念。
3.各教学环节层次分明,衔接自然。活动设计要切合学生实际,尽量使活动多样化。引入教学课题后第一个环节就是展示图片,让学生了解污染类型,紧接着对第一遍听力提出要求,让学生回答对话中提到的是上面我们提到的哪一类污染。
4.教学引入课题后,教师提出问题:造成环境污染的原因是什么 通过分配小组讨论,让学生们商议解决办法,最后告诉学生,保护环境就是在保护自己。为了保护环境,身为学生的我们应该怎么办 让学生写出自己的打算,突破情感目标。Unit 13 We’re trying to save the earth!

Waste sorting (分类) is important.It is environment-friendly and helps to save resources.Now, more and more Chinese people are starting to sort out the rubbish before throwing it away.We are glad to see some fine examples.
However, it is not easy for everyone to do this.Some people may spend so much time deciding the kind of their rubbish.Luckily, twin sisters Chu Siyu and Chu Siqi from Beijing Huiwen No.1 Primary School developed an app to help solve the problem.
The app is easy to use.When users need to throw away their rubbish, they open the app first.In the app, they can find the names of different rubbish.Then, they choose a kind of rubbish in the app, and the right rubbish bin will open.This not only helps users to do waste sorting quickly but also allows them to throw away their rubbish without touching the bin.It is more sanitary (卫生的).
The app also makes use of speech recognition (语音识别) technology.With the help of this technology, users can just speak out the name of the rubbish, and then the rubbish bin will open.How helpful!
Waste sorting isn’t really difficult, and we just need time to get familiar with it.Of course, technology can help us to do it better.If we can do it together, we can help save our planet.

(2023·湘潭中考)
People are getting more worried about the effect (影响) of fast fashion on the environment.
Fast fashion is making clothes in large numbers at a low price.Factories make 100 billion (十亿) pieces of clothing every year.The fast fashion business is doing great harm to the environment.Many of the clothes end up in rubbish bins and are not recycled.A French scientist wrote: “Every year in Europe, four million tons of clothing ends up in the rubbish.Less than 1% of this is recycled.” Another bad effect on the environment is caused by the chemicals (化学物品) used to make clothes.These also cause health problems for people working in clothes factories.
The way people buy clothes is making the problem of clothing waste worse.Many years ago, people went to stores and tried clothes on.They spent more time and thought more carefully before buying clothes.They also wore them for longer.Today, people order cheap clothes online.And if they don’t like them, they send them back.Some people buy clothes and never ever wear them.This is leading to a throw-away society.
So next time before you buy new clothes, think carefully if you truly need them.If not, don’t buy them! Your action will make a difference to the environment.
( )6.Fast fashion is making _______in large numbers at a low price.
A.rubbish B.clothes C.books
( )7.The French scientist wrote that _______of the clothing was recycled.

Wind power is a very clean source of energy.This is how wind power works.Wind makes windmills spin (旋转).When the windmills spin,they make electricity.Then we can use the electricity.
A lot of people think that wind power is new,but that’s not true.For thousands of years,people have used wind to sail boats and move water.We still do those things today,but these days we mostly use wind power to make electricity.
Wind power is a very popular source of energy.Most people think that we should use it more and more.First of all,it’s clean.Windmills don’t pollute the environment at all.Second,we can use wind power forever.After all,we will always have wind.Also,wind power is cheap,and it’s getting even cheaper.
A lot of people don’t understand wind power very well.They believe that there are problems with wind power,but many of those problems are not real.For example,some people say that windmills are dangerous for birds.That used to be true,but it isn’t true anymore.Old windmills killed birds because they spun very fast.New windmills spin slowly,and they aren’t dangerous for birds.
However,there are real problems with windmills.One problem is that many people think windmills are very ugly.This is a problem for some people because windmills are often in very pretty areas.Also,wind doesn’t blow all the time,so we can’t use wind power all the time.Finally,windmills are noisy.
Wind power is becoming more and more common.Right now,more than 80 countries use wind power.About 2.5 percent of the world’s power comes from the wind.For some countries,that number is a lot higher.Wind power gives Denmark more than 25 percent of its electricity.
1.Wind power can be turned into when windmills spin.
2.People have used wind to and move water for a long time.
3.New windmills don’t because they spin at a slow speed.
4.One of the real problems with windmills is that they .
5.Do you think wind power can be used the most popularly in the world Why or why not
教学总结与教学反思
1.本单元教学,授课教师与时俱进,努力挖掘学生的现实生活资源,积极以学生的视角来关注社会生活,尤其是学生所关注的热点话题,选取学生很喜欢的并津津乐道的歌星的视频引出本单元教学的话题:环境污染,激发了学生对本章节的学习兴趣。
2.图片展示贴近生活,引起学生共鸣。在导入环节中展示不同污染类型的图片,贴近学生的生活,学生用英语描述起来比较容易,提高了学生的积极性。之后展示“破碎的地球”和污染给人类带来的危害,带给学生视觉上的冲击和强大的震撼力,深深触动学生,使学生获得印象深刻的感性认识,从而引起学生思想上的共鸣,于是就更加坚定了“保护环境,从我做起”的信念。
3.各教学环节层次分明,衔接自然。活动设计要切合学生实际,尽量使活动多样化。引入教学课题后第一个环节就是展示图片,让学生了解污染类型,紧接着对第一遍听力提出要求,让学生回答对话中提到的是上面我们提到的哪一类污染。
4.教学引入课题后,教师提出问题:造成环境污染的原因是什么 通过分配小组讨论,让学生们商议解决办法,最后告诉学生,保护环境就是在保护自己。为了保护环境,身为学生的我们应该怎么办 让学生写出自己的打算,突破情感目标。
