Pollution means adding dirty or harmful things to land，air，water and so on.
As a result，they are no longer pleasant or safe to use.Pollution is bad for animals and plants，and it even makes people's health in danger.In our daily lives，we can see different kinds of pollution in many places.There are three main forms of pollution：land pollution，air pollution and water pollution.
Land pollution is caused by solid waste，such as cans，bottles and some plastic things which aren't broken down quickly.It makes the environment look very bad.However，air pollution is more serious than land pollution.It is much worse in cities and towns because of the fumes（廢氣） from traffic and the waste from human activities.When people drive their cars，fumes which are most made up of CO2， NO2 and SO2 are given off.After the gases get into the air，they may mix with clouds.Then they will become some harmful chemicals falling on the ground with rain.It is one of the reasons for soil erosion（水土流失） which is one example of water pollution.
Various kinds of pollution will cause many health problems.People have realized they must change this serious situation.There are many ways to control pollution.Developing alternative energy（替代能源） is very popular in many countries.China，for example，has made up its mind to be a leader in this field.It is trying hard to make full use of the energy from the sun and wind.It has paid plenty of money to make electric cars and trains instead of traditional traffic.We should also take action to make our environment cleaner every day.Take cloth bags while going shopping and drive cars less.We have only one earth.
We must take small steps now to help protect our environment for the future wherever we are.

1．Playing video games can be a fun way to spend time with friends.In some schools，teachers use games like Minecraft to encourage teamwork and communication.
But for some players，gaming is an unhealthy habit.They stay up late playing games.They do little or no homework.They give u other hobbies and pay little attention to their families and friends.The video-game world seems a friendlier place than the real one.
Mental （精神的） heath experts have taken notice.The World Health Organization （WHO） listed"gaming disorder （電玩失調(diào)癥）" as a disease （疾?。?A person may have the disorder if gaming has done harm to his or her relationships with family and friends，and if it has influenced his or her daily activities.
Not all experts agree that over-gaming should be called a disorder.They say people who spend too much time on video games may develop other mental health problems.These should be treated first Others think WHO did the right thing.Clifford Sussman is a doctor who treats gaming addiction （癮）.He says those kids often get angry easily and it makes everything difficult for them to complete，like schoolwork.
Sussman advises tracking （跟蹤） how long you play.He says you should take at least an hour-long break after every hour of play.The brain needs time to recover.
Young gamers who think they might have a problem should ask an adult for help.Sussman suggests you first answer a simple question： "Are you in control，or is the game in control？"

3．根據(jù)短文內(nèi)容，選擇最佳答案。
Once there were many thousands of Gourma Desert（沙漠）elephants in Mali，a country in West Africa.Now，there are fewer than four hundred.
Why did the number of the elephants drop so quickly？On the one hand，the elephants' main lake，their only water source （來源），dried up.On the other hand，the land which the elephants lived on was overused by humans.
To protect the elephants' living environment，the Mali Elephant Project（MEP） was started in 2007.MEP met with local people and helped them make rules of using land and water.As a result，the situation became better and there was more food，forest and grassland.
However，from 2012 to 2016，poaching（偷獵）and illegal trade in the elephants increased rapidly.Eighty-three elephants were lost in 2015，and another fifty-one elephants were killed in 2016. "If this situation goes on，all the Gourma elephants will be killed by 2020，" said a member of MEP.
Luckily，the voice of MEP was heard.More organizations（組織）have joined together to educate the local people that trading elephants is against the law.Elephant poaching has dropped to a very low level.The local people have learned to live peacefully with the elephants，one of the wildlife treasures in the world.
