     Fashion isn't very environmentally-friendly because it makes people buy things they don't need, just

because they're new. We want to take care of the environment, we don't want to pollute the air and we

don't want to waste energy and resources. But we also want to be fashiona-ble. How can we buy fashionable

clothes and protect the environment?

     Old styles are fashionable again, so one way is to buy second-hand clothes - recycled clothes. Another

way is to buy fair trade clothes. These clothes are either recycled or made in a way that protects the

environment. They also protect the people who make the clothes.

     Surprisingly, white cotton is one of the least environmentally-friendly crops of all. To protect the cotton,

the growers use chemicals that pollute water, make farm workers ill and kill wildlife. New materials, such as

hemp and bamboo, grow quickly and are more environmentally-friendly. These materials are very soft, and

look fantastic. The best materials are coloured using natural dyes, made from plants.

     Environmentally-friendly clothes are practical but until now they were often dull. Now fashion-designers

are working with these materials and the clothes are beautiful as well. So now we can buy fashionable clothes

that are also environmentally-friendly.

1. Why do people often buy things they don't need? Because ________.

A. new things can be more comfortable

A. people pay more attention to our environment

Have you ever heard of blogs (博客)? If you haven’t, you should have. It’s here, it’s growing and it’s having an influence on our life. Surf the Internet and you’ll find blogs everywhere. A blog, shortened from “weblog”, is a public Internet journal written by one person or a group of people. It is a website in which a person or a group can place news, personal thoughts, text, photos, video or audio files, or links upon which visitors can comment. A blog lets you post on the Internet without having to know web design or be technical. You are given an environment to make dated entries on the topic of your choice which are “published”, so other people can read them.

Authoring a blog, maintaining a blog or adding an article to an existing blog is called “blogging”. Blogging has revolutionized Internet publishing in the last several years because it gives everyone with Internet access the opportunity to become an online writer. Objects, such as “text and photos” in a blog can be called “blog posts”, “posts”, or “entries”. The person who posts these entries is called a “blogger”.

Now, somewhere around the world, a blog is created almost every 6 seconds. Because it’s great potential, Bill Gates views it as important as e-mail, BBS, and MSN. He’s trying to make blogs the important tools for future business communications.
