Since July 2019， Shanghai has been the first city to sort their garbage．Staring on May 1"．2020， Beijing also became one of the members by introducing a new garbage sorting policy．Green garbage has come to China．

In the past， people put a lot of garbage into one pile and then took the garbage to landfill sites．These landfill sites， however， could pollute the land and water． So， if we can find ways to reuse or recycle more garbage， then we will cause less pollution．

The new plan asks people to put their garbage into four different boxes， one for each type of garbage． The brown box is for "wet garbage" （such as food and drink waste）， The red one is for harmful waste （such as batteries and electronics）． The blue one is for recyclable things （such as paper and plastic）．And finally， the black one is for"dry garbage" （everything else）． This "sort your garbage" plan is the same as other plans used by cities around the world． These plans have been very successful． In Canada， it's expected that 85% of plastic will be recycled by 2025．

Why should we sort our garbage？The reason is that we are producing increasing amount of waste every year．It's reported that Chinese cities produce over 200 million tons of waste each year．Reducing that amount will surely help the environment．

However．the garbage sorting is a long journey as it takes time for people to learn and form a habit．More cities are on their way．By 2005 ，it's hoped most Chinese cities will complete the building of garbage sorting．

B．	The blue box．
C．	The red box and the black box．
D．	The brown box and the blue box．

（3）What's the structure of the passage？ （P ＝ Paragraph） 　　

（4）Why did the writer write this passage？ 　　

A．	To sum up some right ways to protect the environment．
B．	To give some successful examples of sorting garbage in some cities．
C．	To show us that the landfill sites polluted the land and water．

Recycling has become more and more important． As time goes by， it is rapidly changing around the world．（1） 　　．

More goods will be made of reused materials．You'll find more clothing，toys，park benches that are made of recycled water bottles．Buildings and furniture are made of renewable wood and steel．（2） 　　．

Consumers（消费者） will become cleverer． Shoppers will turn to companies that produce green products．（3） 　　． They want to know how the materials come from， how food is grown and so on．

Less plastic packaging（包装）． We find it difficult to open a bottle of pills or a new toy and it's a waste of resources． Don't use plastic bags when we go shopping．（4） 　　． Everyone should be a greener person though it will probably take longer for all plastics to disappear．

Actions speak louder than words （5） 　　． Companies should make efforts to reduce materials for packaging as well． The government will take measures to change the situation． In the next ten years，we'll still have a long way to go．

Maybe you should sit down before you read this． It's a little frightening． Your sitting may be killing you．

Health experts say the U．S． adult now sits about 6.5 hours a day. That is up about an hour a day compared to 2007． The news is even worse for teens． They sit eight hours each day．The information was put out by the National Center for Health Statistics．It has collected the numbers for the past 16 years．It is worried about what it has found．

Research shows that people who are not active can get sick． Their bones get weaker． They burn fewer calories （卡路里）． That makes them more likely to put on too much weight． They might even get diabetes （糖尿病）． They are at risk for high blood pressure and heart problems， too．

Some experts also think sitting too much can influence how your blood moves through your body and how well your body fights off illness． Being active helps in lots of ways． It can make you happier， burn more calories and give you more energy． It can also help you sleep better．

About 60% of people in the U．S． watch at least two hours of TV each day． That number has stayed about the same in recent years．

Computers are the biggest reason for more hours spent sitting． Computer use outside of work or school has gone up for all age groups． Now， 50% of adults spend at least an hour of their free time on a computer each day． That is up from 29% in 2003．

About 53% of teens now spend at least an hour of free time on computers． So do 56% of kids． As many as 1 in 4 people who use computers use one for three hours or more outside of work and school．

Maybe a lot of thin people will be worried about their health if the inside fat matters．

Some doctors now think that the inside fat around important organslike the heart or liver could be as dangerous as the outside fat which can be noticed more easily．

"Being thin doesn' t surely mean you are not fat，"said Dr Jimmy Bell at Imperial College．Since 1994，Bell and his team have tested nearly 800people with MRI to create "fat maps" showing where people store fat．

According to the result，people who keep their weight through the food they usually eat rather than exercise are likely to have major deposits （堆积物） of inside fat，even if they are thin．

Even people with normal Body Mass Index （体重指数） scores can have surprising levels of fat deposits inside．Of the women，as many as 45percent of those with normal BMI scores （20to 25）actually had too high levels of inside fat．Men were nearly 60percent．

According to Bell，people who are fat on the inside are actually on the edge of being fat．They eat too many fatty and sugary foods，but they are not eating enough to be fat．Scientists believe we naturally store fat around the stomach first，but at some point，the body may start storing it elsewhere．

Doctors are unsure about the exact dangers of inside fat，but some think it has something to do with heart disease and diabetes （糖尿病）．They want to prove that inside fat does harm to the body' s communication systems．

The good news is that inside fat can be easily burned off through exercise or even by improving your eating habits．"If you want to be healthy，there is no other way．Exercise has to be an important part of your lifestyle，"Bell said．

How much sleep is enough？

To stay in good health，some expert in the US say，adults should get seven to eight hours of sleep．Teenager need nine to ten hours．And pre﹣school children need more than 10 hours of sleep a night．

Experts say the quality（质量）of our sleep becomes poor as we grow older．This happens because the brain unit that controls sleep begins to weaken slowly as we age．

Experts say the change starts in our 30s．By the time we reach our 50s，a person may have lost 50 percent of their ability to have a restful sleep.

These people have trouble failing and staying asleep through the night．From middle age on，these problems only get worse，and they can have a bad effect on their health．

Signs that show you may not be getting enough sleep．

You're always hungry or you've got unwanted weight．If you are in short of sleep，certain chemicals in your body will not work well and tell your brain in time that you have eaten enough．

You have trouble making decisions．Not having enough sleep may make your brain work slower in problem solving．

You have trouble remembering things．Sleep helps prepare the brain for new memories．

Your feeling changes unreasonably．People who don't sleep well may feel unable to control their feelings．

You are having trouble seeing．If there is a shortage of sleep，you may not be able to see thing as clearly as usual．

How to improve your sleep？Here are a few things people can do to get better sleep．

Health experts say that exercise and avoiding work on computers make people go to sleep more easily．A cool room is also a good choice for sleeping well．

Let's say you are taking a walk along the road and you happen to see one or two waste bottles lying on the grass beside the road． What would you do？

You may have different choices． Firstly ，you can leave the bottles there as they are． It was not you who threw them away． Why should you do something about it？ This is quite OK． Secondly， you can pick them up and throw them into a dustbin （垃圾箱）． By doing this，you have walked a step further to help make our homeclean． This action is a better choice． Thirdly， you might want to pick them up and give them to an old man or woman who collects waste for a living． If this is your choice， you have walked even further． You're not only thinking about doing something for the environment， you're also developing yourself to be a person who would think of others and help them．

As for young kids， they may always have such a question："When do I grow up？"Yes! When does a child grow up？ And how can a kid know he or she has grown up？These are interesting questions．As for us，fifteen﹣year﹣olds，who are finishing middle school， we're no longer younger children．We should know whether or not we have grown up． When we start to have a sense of offering a helping hand for a cleaner city and greener world， and when we have a loving heart to think more of others than of ourselves and are ready to help them， we can say that we have grown up．

Remember： If we help others， others will help us． If we do our best for nature， nature will offer its best to us in return !

Why Live Near the River？

Imagine pioneers traveling west in the 1800s． In those days， it was hard to find running water and shops where to buy things． As time went by， most pioneers had to make their homes near a river so that they could get water easily．

How did rivers help people live in the past？

Back in the pioneer days， people grew their own food，caught their own fish，and collected their own water．（1） 　　People also used rivers as roads，traveling on boats．Traders shipped goods （货物）to people from other areas．

（2） 　　

When building many factories right next to rivers for the water's power to make machines work， some people choose to live near a river for working． They use the river to ship large goods， and some of them work at these factories where power factories provide electricity to homes and businesses． （3） 　　

Who wouldn't want to live near a river？

Some people are nervous about living near rivers because rivers can cause floods （洪水）． Every once in a while， floodwaters rise higher than a house， ruining （泡坏） many things in the house．（4） 　　Such waste causes water to smell bad and pollutes the crops （庄稼） we eat． Water and crops in polluted areas can make people very sick．

How do people decide where to live？

（5） 　　Rivers can provide jobs and fun activities in a beautiful place． However， those living by rivers should be willing to accept possible problems as well．

A． Why do people live near rivers now？ B． Why did people want to live near a river？ C． Some factories put their waste into rivers． D． Staying close to a river was easy to get water for living． E． Some factories stop waste water from running into rivers． F． People who carry goods onto ships live near the river， too． G． People should think over the possible risks before deciding where to live．

There are many ways to help improve your health like eating healthy food． taking exercise and getting medical help． But the easiest and cheapest way to improve your health is just to sleep eight hours or more every night． The general sleeping rule is that the younger you are． The longer sleep you need． But regardless of（不管）age， some people need to sleep more while for some a few hours is enough．

The problem with sleep is that more and more people in the world are not sleeping enough．According to the World Health Organization over half the people in the world may be sleep﹣deprived． Having less sleep not only makes people feel tired but also causes accidents． In the United States alone， sleepy drivers cause at least 100，000 traffic accidents a year． Also sleep problems can cause medical problems such as high blood pressure（血压）．

Why are so many people sleep﹣deprived？ Part of the reasons may be cultural． In the   American culture， people put a higher value on work than on sleep． In fact， peopele who sleep a lot are usually seen as "lazy"． Also， you can sometimes hear some people say proudly that they don't have much time to sleep． they only sleep four or five hours a night． It seems that the less you sleep， the more work you'll do．

How do we teach these people to learn the value of sleep？ Perhaps they may listen to the advice of Dr． James Maas． an expert（专家） in sleep．   He says ，"Sleep is like a credit （信用卡） card． When you sleep less． you are only borrowing time． You always have to pay it back． The more hours you don't sleep， the more hours you should't sleep to "pay back" the hours on your 'sleep credit card．'"

For those who value work more than sleep， they should listen to what a famous person once said． "Don't think you will be doing less work because you sleep during the night． That is a foolish（愚蠢的） idea which is held by people who have no imagination． You will be able to do more．"

Cycads（苏铁）grow in warm places．They are tall and green all year round．Their leaves grow on the top and flowers seldom come out．Some have bright orange fruits．They usually need hundreds of years to grow into adult plants．

Cycads are facing problems now．In South Africa，the situation of cycads is getting terrible，but this has drawn little attention from the public．"In fact，there are 38 kinds of cycads in South Africa．Among them，2 kinds have disappeared since 2003 and 25 kinds are in great danger，"said a gardener．"Do you know what the loneliest plant is in the world？It is Wood's Cycad．Someone found it in a forest in 1895．It is the only one of its kind．"

So what causes cycads to be in danger？Surprisingly，the danger is from the people who love them most． These slow﹣growing adult cycads even sell for tens of thousands of dollars each．As time goes by，they have become a symbol（象征）of wealth and position（ 地位）in society．This makes cycad lovers want to own more． Cycad lovers buy and plant them in their private gardens．As a result，nearly all these cycads die because the living conditions have changed．

Recently，South African government has taken some actions to protect cycads from being stolen traded．At the same time，people around the world should also work together to protect the plants．

（1）The flowers of Cycads come out once a year．

In the 13th century． Marco Polo the world known Italian travelled， saw many wonderful things in China． One of the things he discovered was money made of paper． People in the West did not have such kind of money until the I5th century． However ，the Chinese began to use it in the 7th century．

Paper was invented by a Chinese man called Cai Lun almost 2，000years ago． But it was not made in Europe until the year 1100． Four hundred years later， a German discovered that he could make the best paper from trees． After that countries rich in forests， such as Canada ，Sweden， America， Finland became the most important ones in paper making．

Paper can be used in many ways． The common uses include newspapers magazines and books． But do you know that paper can be used for keeping warm？ In Finland． the farmers wear paper boots to keep their feet warm in the snow． And even houses can be insulated（使绝缘）from heat or cold with paper．

However． we have to understand that paper still comes from trees now． If we keep on wasting so much paper， there will not be any trees left on the earth some day in the near future． Every day people throw away about 2， 800tons of paper in our city． It takes 17trees to make one ton of paper． This means that we are cutting down nearly 48.000trees every day． The fact is that it takes more than 10years for a tree to grow．

So we must start saving paper right now． We can use both sides of every piece of paper． We can make useful things out of used paper． We can use china cups instead of paper ones． When shopping， we can use fewer paper bags and reuse them if we have some

In short， we should keep a balance （平衡）between using paper and protecting trees， and do it now before it is too late．

Eleven countries are building a great wall of trees across Africa． It is called the Great Green Wall．The aim is to bring life to the dry lands and help to fight the bad environment．

The wall is 8， 000kilometers long and 15kilometers wide． It covers from Senegal in the west to Djibouti in the east，on the south of the Sahara Desert（撒哈拉沙漠）． So far，Senegal has made the best progress by planting about 11， 000，000trees．

Many years ago， there were few trees in that area and the winds used to be very strong． It was harmful to the fields． Also， there was little rain， so few plants could grow and many people went hungry．Since the tree planting project started， the trees have provided food for the local people and increased the wetness（湿度）of the air． Little by little， there appeared green fields for people to grow plants．

The project which began in 2007is supposed to cost a total of 8， 000， 000， 000dollars． Many countries are trying their best to help to continue the planting． So we will be able to see the whole green wall across Africa in the near future．
