5. A letter on talking bus service in Beijing 英文书信(北京公共交通)

　　Dear Tony,

　　I am glad to know your grandpa is coming to Beijing.

　　Yes, your grandpa is right. The bus service in Beijing is really good now. there are more than 900 bus lines all over Beijing and bus can even take you to some small villages. Besides, special(yellow) seats are provided on buses. People do not have to spend a long time waiting for a bus and the tickets are very cheap.

　　I like taking a bus because I think it is comfortable and also good for our environment. So it is a good choice for your grandpa to travel by bus in Beijing.

　　If you have more questions, please ask me.

　　Yours,

　　Liu Jing

　　6. Pollution around us(保护环境)

　　In recent years our life is becoming better and better.

　　But our environment is becoming worse and worse. It’s very bad for our life. Now many people have air-conditioners and cars, they produce (give off ) waste gas. More and more trees are being cut down. There are so much sand on the earth (leaving only sand ) . We often see factories pour waste into rivers or lakes. Water in the river is quite dirty. We haven’t enough clean water to drink in cities. Now we are in danger. It’s very necessary and important to protect the environment well.

　　I think if everyone tries his best to protect the environment, the world will become much more beautiful, and our life will be better and better .

　　Everyone knows that we can do a lot of things in order to live a low-carbon life.

　　Firstly, we should save water and electricity. Secondly, we had better sort out rubbishes, which include recyclable and non-recyclable rubbishes. Thirdly, we could re-pick up our handkerchiefs, and use tissues as little as possible so we can stop more tress from cutting down. Last but not least, please try to walk if you have more free time, and ride bikes or take buses as often as possible.

　　提示词汇：网上购物 shopping on the Internet(online shopping) ，京东商城 360buy.com

　　Recently，we talk about advantages and disadvantages of shopping on the Internet. Some people think that it is very easy for us to go shopping online. The shops on Internet ,for example taobao.com, 360buy.com are open for almost 24 hours a day, so we can buy something we want at any time if we like. What's more, we needn't to wait for a long time.

　　However, others believe that we can only see the pictures on the Internet and can not touch or see them, It is difficult to say whether it is good or bad. We will have more problems when the things are not good. Besides, it is not a good news for some girls because they enjoy going shopping in the market with their friends.
