请听一段独白，完成第14至第16小题。
People always ask me why I only travel the hard way! A lot of television travel programs are about relaxing holidays on the beach, but I’ve only ever made programs about really long trips. The last trip I did was a 50,000-mile journey around the Pacific Ocean, and it took 12 months. But my very first trip was a ‘round the world’ journey, and the most difficult one was probably the car journey from the North Pole to the South Pole.
As you can imagine, I’ve seen a lot of the world! I’m lucky to be in really excellent health, but life is very short and I’ve done so much traveling that I want a change. Traveling long distances makes you very tired, and although it’s still a great pleasure for me, I want to do something more relaxing now.
I think my next television series might be made nearer England. There’s some really interesting work going on in Wales, where they’ve just found what remains of a 2,000-year-old town.
But I hope the programs I’ve made about the really long trips will encourage other people to get on a plane and have some adventures. Some people seem to be afraid of going to a strange country and perhaps being ill there, but maybe they realize now that if I can do these trips, so can they…

There are many things we need to know, but we do not learn them at school. For example, if we want to use our money wisely, we need to shop carefully. We need to know how to compare the prices of the same things in different shops. We also need to know how to make the best decision when we shop. It is a life skill, and we need to practice it in our daily life.

What does it mean to be green?“Green”is more than just a color. It also means taking special steps to protect the environment－the water, the land, and the air we breathe. Why green? Plants are green, and without them the earth wouldn’t be such a lovely home for us human beings.

Sometimes people can call ours a “throwaway society”. That means we are always throwing away old things and buying new ones. Many times, if you no longer need something, someone else just might need it. For example, if your brother is old enough not to play with his plastic bike, why not give it to another family who has a little kid so that they don’t need to buy one? And one less large plastic toy doesn’t need to be produced.
Recycling (回收利用) has never been easier. Many organizations will pick it up right in front of your house and some towns even require (要求) it. Tell your mom or dad you want to become “Chief of Recycling” for your family. Now that you know what things you can recycle, find a place to keep them. Make sure you encourage everyone in your house to think whether things can be reuses or recycled before they’re thrown away.
Almost everyone likes traveling. But next time before you travel around the world, took a look at your own backyard. Is there a place where you could plant a tree or put in a little fruit or vegetable garden? If so, get there and get your hands dirty. Then you can watch with pride as your tree takes root, and your garden plants grow into big plants full of ripe, red tomatoes or tiny, juicy blueberries. Who knew being green would taste so good?
6. In the first paragraph, the writer introduces the topic of the passage by ________.
A. telling an interesting story

C. giving some special examples
7. In a “throwaway” society, ________.
A. people shouldn’t produce any plastic things
B. people can get anything they want from others
C. people always throw away the used things and buy new ones
8. To be “Chief of Recycling”, you should ________.
A. recycle things all by yourself
B. ask your family to use the old things all the time
C. find a place to keep the things that can be recycled
9. You are advised to run a fruit or vegetable garden in order to ________.
A. create a green environment
B. make a lot of money
C. get your hands dirty
10. The purpose of the passage is to tell us that ________ .
A. we must enjoy the nature
B. we had better eat more green food
