Pollution is one of the biggest problems in the world today.In many places，rubbish is thrown into lakes and rivers.（1）
In some cities，the air is filled with pollution.（2） If it is not cleaned up，more people will be hurt.
（3） Land and water pollution kills many animals every year.
If we do not act to improve the environment，more living things will be killed by pollution.
（4）
We should separate rubbish into different groups.In this way，it can be recycled and reused.We had better plant more trees.（5） What's more，we shouldn't put the waste into lakes or rivers.
If we can do these，we will make the world a better place to live in.
A.This makes some old people and children ill. B.As well as people，animals are also harmed by pollution. C.We can make our lakes and rivers cleaner and cleaner. D.It's time for all of us to take action right away! E.Because of this，these places have already been polluted. F.Trees reduce dust and help keep the air clean. G.A few of us should take action to protect the environment. |
The problems with the environment are becoming more and more serious．You may think it is the government's job to take action and it is difficult for the individual（个人）to protect the environment．In fact， there are several easy things that can be done to make a difference．
You can start your cation by learning to recycle． Although this appears really simple，there are many people who still throw glass bottles and metal cans（金属罐）into their common rubbish bins．Do you notice that our government has put many special rubbish bins in public places？They all have glass and metal recycling signs．If you spend a few seconds washing the cans and bottles and put them into the rubbish bin， you will be on the path to protect the environment．
One more big waste product is newspaper． Most people will take their newspapers and throw them into rubbish bins when they finish reading them．In fact，there are many other things you can do with an old newspaper． For example，newspapers are something useful for a perfect shine．
What else you can do is walking a bit more． Many people usually get into their cars and drive one block to get cola at the local shop．If you walk to the shop，you can not only spend less time，because you needn't try to find a parking place，but you will save money on oil． If you wish to save even more on oil，take the chance to share the same car with others．

At 8，844.43 meters high， Mount Qomolangma is the tallest mountain on Earth． While it is famous for its beautiful views，parts of the mountain are facing a problem： rubbish． Every year， thousands of visitors throw away tons of rubbish， such as bottles and plastic bags．
According to the UN，over 140 tons of rubbish has been left on the mountain． To reduce rubbish， China is limiting （限制）the number ofpeople who are allowed to climb up the north side of the mountain．Only 300 people will be allowed to climb it， and only during spring．
Local people cleaned the mountain last year，removing rubbish at a height of 5，200 meters．They collected about 8.4 metric tons（公吨） of rubbish．

Tide is the regular rise and fall of the ocean level caused by the movement of the sun， the earth and the moon． It is considered a promising source of green energy to produce electricity in coastal areas．
To make use of tidal energy， we need to build tidal power stations． The bays and the river mouths where the tide is high（the tidal range is more than 10 metres） are usually perfect sites to build tidal power stations． There are many such places in the world． According to the IRENA （ the International Renewable Energy Agency）， by just using 2% of our coastlines， we can produce 4，383TWh of ocean power each year， enough to meet 16.4% of the world's electricity needs．
To build a tidal power station， we need to build a dam． In the dam are many turbines and on each turbine there is an electric generator'． When the tide rises，water comes through the dam，the turbines turn and the electric generators work， producing electricity．When the tide falls，water goes out through the dam， the turbines turn again．The electric generators continue to work．
Tidal energy has its advantages．Using tidal energy to produce electricity is much cheaper than using the traditional energy， like coal or gas． For example， the Rance Tidal Power Station in France has been there for over 50 years， producing around 5.000.000TWh of electricity each year． The cost is only 1.3 cents/TWh．
Tidal energy can be used nearly 24 hours a day． As long as the sun， the earth and the moon exist，we can use it to produce electricity． But without sunshine， there is no solar energy． When there is no wind，electric generators will not work． In addition， with the development of modern technology， tidal energy can be stored and used to produce electricity continuously．
However， we still have some problems to solve． It is difficult to build a dam in the sea， and the cost is very high．Moreover it's expensive to keep a tidal power station in its best condition．Scientists are working on them．
（1）A tidal power station is best built ．
A．at a river mouth with wind
B． along the coast with waves
C． In a bay with tide high enough
D．in coastal areas with sunshine
（2）The underlined word "turbine" in Paragraph Three is a machine to ．
A． make the tide rise and fall
B． make an electric generator work
C． let water go through the dam
D．keep the dam in good condition
（3）What advantage does tidal energy have？
A． We can use it to get useful tide．
B． It can improve the ocean environment．
C． We can use it nearly all the time．
D． It meets 16． 4% of the electricity needs．
（4）How can we make better use of tidal energy？
A． By digging more bays and river mouths．
B． By building cheaper tidal power stations．
C． By closing traditional electric power plants．
D． By using tidal energy to replace other energy．
When you have a cold，your friends can't visit you because they don't want to get a cold.When you are part of a family，if one of you gets a cold，often all of you get it.
（1） .Below are four ways to help stop a cold spreading and to feel better again.
●Wash your hands.
Washing your hands is the most important way to stop the spread of colds.Cold germs （病菌） are spread by touch.The germs get onto your hands and from there into your eyes，nose and mouth.Wash your hands carefully using soap and hot water.（2） ，they will be much less likely to get the cold.
●Cover your nose and mouth.
There is a saying that "coughs and sneezes spread illness". （3） when coughing and your nose if sneezing.That way，the cold germs won't get onto your hands and spread to things you touch such as doorknobs，tap handles or cups and plates.
●（4） .
Cold germs are spread very easily.You can use a disinfectant （消毒的） cleaner to clean doorknobs，taps，toilet handles.Be sure to use only your own towel，toothbrush and cup.
●Take care of yourself.
（5） .Eat healthy simple foods such as soup or rice.Get enough rest and sleep.Stay in bed，read a book.Do your schoolwork and practice your English!
Remember that a common cold only lasts a few days.You will feel better soon.
A.Some cold medicines can help stop aches and fever
B.Cold germs can be spread by coughing and sneezing
C.If all the members of your family wash their hands too
D.Always use a piece of soft paper to cover your mouth
E.When you wash your hands every half an hour
F.Clean your house
G.There is no good method of treating the common cold
How to Get Children to Stop Touching Their Faces
Kids seem like they're always touching everything in their environment， from tables and chairs to doors and stairs． Since those surfaces may hold germs（细菌），you can help your child avoid illness by encouraging them not to touch their face throughout the day．
（1） Once your child is about 3 years old， you can begin having conversations with them about avoiding germs， including the importance of washing their hands and how touching their face can spread germs to their nose and mouth． While just knowing this information probably won't help them break the habit， it can help set the groundwork．
（2） If you don't want to criticize（批评） your child when they forget， it is important to remind them when you see them with their hands around their face or mouth． Sometimes， just knowing that they 're doing it will be enough to help them stop doing it．
（3） It can be hard to remember sometimes， but look for chances to let your child know when they're doing a good job of keeping their hands away from their face． Encouraging words can be a really powerful motivation（动机） for kids to keep trying when they 're learning something new．
（4） Children often touch their faces or mouths without thinking about it． Many times， it's just because they're bored and they're looking for a way to excite themselves． If you think that might be the case， try giving your child a toy they can hold onto．
A． Point out any time you see your child touching their face． B． Encourage your child to wash their face carefully． C． Offer your child something they can hold． D． Explain why it's important if your child is old enough． E． Praise your child when they aren't touching their face． |
（5）The passage is most probably chosen from the part of in a newspaper．
A． News
B． Health
C． Sports
D． Business
We should not use more water than we actually need． If we do， we will not have enough water in the future． （1） It is not a difficult question to answer． If we remove more fresh water than nature replaces， we have taken too much．
Many cities run campaigns（运动）to get people to stop wasting water． They show them ways they can cut back on water use． （2） What's more， they carry out programs that offer money to reduce water use． For example， they give people shower heads and toilets that use less water． （3）
Another threat（威胁）to our water supply is pollution． When our sources of fresh water get polluted， we can no longer use this water． This also endangers（危及） the animals that depend on the water．
（4） We can save lots of water by not letting taps（水龙头） run while we brush our teeth or by turning off taps right after washing hands． By collecting cold water when were taking warm showers， we can also save water． （5） In this way， we can make full use of water．
A． However， just how much is too much？
B． There are several things we can do to save water．
C． Finally， they make laws to control the use of water．
D． We don't have to let the cold water run until it gets warm．
E． They also increase water bills for people who use too much．

I'm a virus （病毒） for the common cold． It has been a long time since I infected（感染） humans last time． Today I tried to infect a boy in a primary school all day． His name is Sam． I waited on his desktop， and when he touched the desk I jumped on his finger． Unluckily， Sam didn't touch his eyes， mouth or nose．Then， right after class， he washed his hands．Now I'm full of soap and sitting in a sink!
Tuesday， January 22nd
This morning I jumped into the nose of Sam's best friend， Bill．Unluckily，the mucus （粘液）in his nose caught me． I thought it was over for me，when suddenly Bill sneezed while he was talking to Sam． I knew that would send me right into Sam 's face! However， Sam quickly gave Bill a tissue， and Bill sneered into that instead! Infecting people is harder than I imagined．
Wednesday， January 23rd
I'm feeling very unhappy today．Some scientists caught my friend Harry and put him under a microscope． Harry is a flu virus and he's a dangerous little guy．Besides，Sam ate all his vegetables today．He's exercising， and he's getting eight hours of sleep every night． His body is too strong for me!
Thursday， January 24th

What do you do with your rubbish？Throw it out？You don't know what you're missing!Look closely at the two figures on your left.They were made from things most people throw away.The figures were made from used bottle caps.Those two bottle﹣cap figures were exhibited （展示） in a museum.
Folk art is art made by common people who have not been trained as artists.Their work is often based on traditions in their culture.Fine art，on the other hand，is usually made by people who have had training in art.Works of fine art are valued for their artistic beauty.They are supposed to be looked at but not used.Works of folk art，however，are often made for everyday use.
There were more than 800 pieces of folk art from nearly 50 countries in the exhibition.All of the pieces were made from used metal，wood，cloth，and plastic.The artists come from many different cultures.Still，they all share one thing.They take objects that are normally thrown away and change them into objects that are beautiful，useful，and fun.The artists may not think of what they do as recycling，but that's exactly what it is.Fine artists might work with expensive materials.They might use expensive tools to shape these materials into works of art.On the other hand，in poor countries rubbish might be the only material folk artists and toy makers can afford.The exhibition shows that a rich imagination is very important when there are only poor materials.Recycled art began long before people began to think about recycling.Some of the objects in the exhibition date from the 1930s.
Even if you don't create art out of rubbish，it's good to save our natural resources.Remember the three rules：reduce，reuse，recycle.If you reduce waste，true things instead of throwing them out，and recycle materials such as paper，plastic，and glass，you will protect the environment.

In 1988，Wang Chengbang retired（退休）from the army.Instead of enjoying a relaxing life，he volunteered to save the soil from desertification（沙漠化）by planting trees in Korla，Xinjiang.
It is no easy job.The high temperature in Korla makes it difficult for anyone to work day after day in the sunshine.Besides，water is a big problem.In fact，Wang Chengbang's work in the first few years failed as very few trees survived（存活）.
But Wang Chengbang would not give up."After trying many different ways，I have learned how to grow young trees in a better way，" said Wang Chengbang.He also worked out new ways to save water.With his hard work，more and more trees have survived.So far，he has planted more than 1.5 million trees.Those green trees prevent desertification，make the air cleaner and protect people from the hot sun.Now，Korla is a model city in environmental protection.
Wang Chengbang is also successful in fighting cancer（癌症）.In 2005，he had cancer and was told that he had only six months to live.However，he continued taking care of his trees rather than lying on the hospital bed."Working is the best medicine.Planting trees helps to fight cancer，" he often jokes.
Now，at the age of 85，Wang Chengbang is still working.
（1）Is it an easy job for Wang Chengbang to plant trees？
（2）How many trees has Wang Chengbang planted so far？
（3）What is Wang Chengbang successful in？
（4）In the summer holiday，do you want to be a volunteer to work with Wang Chengbang？Why or why not？
Do video games do harm to our children？Today，many children spend a lot of their free time playing games on the Internet.In the UK，99%of kids aged8 to 15 play video games every week.This information tells us that the benefits and dangers of video games must be carefully considered.
For many people，video games are fun.They have bright lights，funny cartoons and exciting stories.Everywhere you look，you can see children playing these games.They play on buses and trains，in restaurants and even at school.
Video games are educational too.They make kids think in a creative way and theyhave to move their hands and eyes quickly.This can improve the way that a child's brain works.What's more，video games make children use their imagination.The player has to do many creative things，like drawing，telling stories and building things.Video games are also a good way to teach children about technology because they can learn how computers and other devices work while they play.
However，a recent study suggests that video games can also be bad for children.First，children can download many games for free.This means that parents often don't know if their children are playing violent or scary games.Second，many children spend too much time playing games on computers and this can lead to health problems.Third，if children spend too much time playing games instead of doing homework，they can have problems at school and get bad grades.Finally，video games can affect children's social skills.If children spend too much time playing video games by themselves，they might not learn how to play with their friends.
In conclusion，it seems clear that video games have some advantages and some disadvantages.It is up to parents to know what games their children are playing and how much time they spend on them.Parents should also make sure their children get enough exercise and spend time with other children.

Dogs might have the latest tools in the fight against cancer （癌症）：their noses!Researchers at California's Pine Street Foundation （PSF） say they have trained five dogs to smell cancer on a prison's breath.This could be exciting news.
A dog's sense of smell may be 10，000 to 100，000 times stronger than ours.But can dogs really smell illness？PSF researcher Michael McCulloch says yes. "We were very surprised by how exact they were，" he said. "They were telling who had cancer，and they were also saying who didn't."
McCulloch and his team asked four healthy people and one with cancer to blow into plastic tubes （塑料管）.Special materials in the tubes kept the things of each breath.The tubes were then placed one yard apart.Finally the dogs were allowed to smell the tubes.Each dog had been trained for three weeks to sit when it smelled cancer.Ninety﹣nine percent of the time，the dog sat next to the tubes blown into by patients with lung cancer.The dogs were right 88 percent of the time about breast cancer.
| Dogs in the Pine Street Foundation test were trained to sit when they smelled cancer.How well did they perform？Take a look at this chart to find out. |

| Breath Sample |
Number of Times the Dogs Sat Down |
Number of Times the Dogs Kept Standing |
| Breath from lung cancer patients |
564 |
10 |
| Breath from healthy persons |

The world uses about a thousand million （百万） tons of water a day． Water is a human right and everyone should have their share． Yet more than 700 million people around the world have trouble getting clean， safe water．
Treating wastewater is a good way to provide fresh water for us． And it also helps the environment by keeping waste out of rivers and oceans． 80% of wastewater around the world is not treated at all， and it is running into oceans．
But now we have got the technology to treat and reuse the wastewater．
While 75% of our planet is covered with water， only about 2% is fresh water﹣that comes from rivers， lakes， ice and snow． The rest， 98% of the water， is in seas and oceans． It is too salty to drink． Then desalinationbusinesses come in． More than 19.000 factories have been built around the world， mostly in coastal countries． They process（加工） more than 92 million tons of water every day． But the technology they use requires a lot of energy．
Scientists are working to create a less costly technology． They want to produce 20 times more clean water and make sure everyone has enough． But for now， the world still faces each day with not having enough water for everyone．
