New car problem
Nowadays more and more families own their private cars.Most people would find it hard to think what life could look like without a car.Although cars have led us to a better life,they have also brought us many new problems.
Cars produce wasted gases and smokes,which pollute air seriously.The polluted air becomes poisonous and dangerous to our health.With the increasing development of cars,cities are becoming more and more crowded.There is not enough room for cars to be parked.Worse still,more traffic accidents happen in big cities,even in the countryside.
More cars need more gas.Energy resource will run out one day if more gas is needed.At the same time,some old and damaged cars are thrown away as rubbish.That will cause another new pollution.
Plastic surgery.
As megical technics has been improved,plastic surgery has became more and more porpular.
You can always this on your magzin:One of those celebrities was discovered going to a famous plastic surgery hospital.And maybe this phenomenon does not only belongs to celebrities,maybe one day,you bump into a stranger who claims knowing you turn out to be your high school friend,and out of the blue,she did a plastic surgry.
I cannot help asking myself:What is wrong with this world?Why do people become so desperate to change something that is given by nature?After all,i'm against plastic surgery.
First,in my opnion,plastic surgery is a waste of resources.What's the point of making so many doctors and nurces around you when there are so many people in somewhere else are wating for doctors to save their lives?
Seoconly,beauty is skin deep,one can never change into a better person only by changing his/her apearence!
At last,i wanna say to all these who are eger to do a plastic surgery:If you use your money to save people who need it,you will find yourself become to a person not only beautiful by the cover,but also deep inside.
Trees Are Important to Use
Trees are very useful to people.They provide us with wood and other products.They give us shade and they help to prevent drought and floods.
Unfortunately,in many parts of our country,people haven't realized the importance of trees.They cut them down at will.They are usually too lazy or too careless to plant and look after new trees.As a result,the forests continue to disappear.
Where there are no trees the rain falls on the surface,causing floods,and carries away with the rich topsoil,in which crops grow so well.When all the topsoil is gone,nothing remains but worthless deserted.
The big floods of 1998,in parts of China,have already taught us a good lesson.So every one of us must love trees,protect forests,and keep on planting trees each year.
