帮忙写一篇英语作文,100字到150字左右!大一水平!有两篇,1,have different ways to relax myself .2,traffic is a big source of pollution in cities .

Some students participate in school activities such as clubs and sports. However, others do not take part in school activities but to spend more time on their studies. My view is that take part in school activities is good for our students.
Well,in my spare time,I usually do some sports.For one thing,I can build up my body,for another,I can relax myself.I am crazy about bungee jumping(蹦极）,because I like the feeling it brings to me!I feel thoroughly relaxed from the daily stress.It's wonderful.Apart from bungee jumping,I'm also keen about yoga(瑜伽）。Yoga has become a pretty popular activity among varied people.Yoga is widely spread and accepted especially by the white collar and students,who are usually under great stress.Yoga is a wonderful way to give off their bad mood.I really like yoga.
Besides,when I have extra time ,I will also read books and go jogging.To conclude ,my spare time is colourful and meaningful.
As far as I am concerned, we must balance our study and school activities. After class, we should do some sports or participate in clubs to relax ourselves.

City Pollution Caused By Traffic
As we know,the enviroment of the earth is getting much worse.I think traffic is a big source of pollution in cities.
We must understand where the traffic pollution comes if we want to improve the quality of the air.Maybe there are some examples which could explan the idea.For example,the exhaust gas causing air pollution is one of the reasons.With the increase of the personal car.the exhaust of gas is much more than before.Also,noise pollution is one important component of the pollution.To be reserched,we will become ill if we exposed in th enviroment of noise.Else,dust pollution caused some inconvenient for our life.
What shall we do?Maybe we can change the fuel of the car and creat some new way to reduce the use of the fuel.Also,wen could advise people to drop the personal car and go to work by bus.Only in this way could we live in a clean world.
