Want to save the environment? You probably can’t fix everything on your own, but by taking small steps and keeping the environment in mind every day, you can make a difference,
1. Think Green. Challenge yourself to think about the environment as you live your life. If you shut off lights when you leave the room, turn off your TV when you’re not watching it, you’ll save energy. If you take shorter showers, you’ll save water.
2. Shop Green. Shopping is fun, but buying things you don’t need is wasteful and bad for the earth. Before you buy something, ask yourself how much you’ll really use it. Keep yourself away from buying products with unnecessary packaging (包装), and whenever possible, buy things that were locally made instead of those shipped from far away.
3. Dress Green. Wear green trousers and T-shirts if you want. But what really matters isn’t the colour, it’s how the clothes were made. If you want to help the environment, the best place to find clothes is at a vintage store, but you might not want to buy everything used. No matter where you shop, keep an eye out for products made from environmentally friendly materials like organic(有机的) cotton, which is grown without the use of pesticides ( 杀虫剂).
4. Study Green. What’s better than learning about the environment? Save it while you learn, It can be as simple as using both sides of a piece of paper before you recycle it, or reusing an old textbook :instead of buying a new one. If you want to do more, join an environmental group at your school, and encourage your friends to join, too.
【小题1】The underlined phrase "a vintage store" in this passage refers to (是指) a place where you can buy          .

This is not a diet. It’s a simple way to lose weight. And you don’t even have to give up the food you love or join a gym (参加体育锻炼). You just follow some habits that thin people have. Keep them, and you’ll become thin.
(1) Wake - up
When you wake up in the morning, sit up slowly without using your hands. With legs straight out, bend（弯曲） forward until you feel sore（酸痛） in your back. It will burn about 10 calories.
(2) Start with soup
When you have a meal, order a clear soup, and have it before having the main food. In this way, you’ll feel fuller, so you’ll eat less when the main food comes.
(3) An apple (or more) a day
Apples are full of fiber（纤维） and water, so your stomach will want less. The study shows that people who eat at least three apples a day lose weight.
(4) Stand up and walk around
Every time you use the mobile phone, stand up and walk around. Heavy people sit on average (平均) two and a half hours more each day than thin people. This skill is very important as standing up and walking around will burn 50 0r more calories.
Use these skills, and you will have a big weight loss.
