The earth is changing. Tomorrow it will be different. All the living things on the earth are changing. Even people are changing, and tomorrow you will be different.

　　 There are many kinds of change, and many different things than cause change. People need to realize the changes, to learn to see them, and to learn what causes change.

　　 Human beings must solve many problems so that they can continue to live successfully. War is one of these problems. Disease and natural disaster are problems. Having enough food and energy for the growing number of people in the world is a problem. Most problems can be solved, but some are impossible to solve. The way in which people solve problems affects how long and how well they can live.

　　We need to be responsible for our environment. Being a frugal consumer(节俭的消费者) is one way to help. But, what exactly does that mean?
　　Use It Up
　　You can use things up instead of wasting them. Squeeze that last bit of toothpaste out of the tube. Use the last little piece of soap. Don't throw away any bits of the biscuit at the bottom of the box.
　　Wear It Out
　　You do not always need to have new things. Suppose your sneakers have broken laces, but they still fit you. Repair them and wear them longer. You don't have the latest iPhone until the old one doesn't work anymore. Then you can get a new one. Think twice before replacing something that still works.
　　Make It Do
　　When something you want is not on hand, look for something else that you already have to take its place. Suppose you are packing your lunch for tomorrow and want a butter sandwich. You are out of butter. Have a cheese sandwich instead so that you can use all of the cheese. Learn to fix broken toys instead of just throwing them away. With a little thought, you can make something do, instead of buying something new.
　　Do Without
　　Think about all those things that you would like to have. Do you really need them? How long will you really play with that new toy you saw on TV? Making the things that we want uses up your world's resources(资源). And, getting rid of the things we don't want any more takes up even more resources and space.

【小题5】What does the writer want to tell us?

People mountain people sea? Yes, this means too many people at a place. This is a photo taken in Shenzhen.
Shenzhen’s fast development has made it become China’s most crowded city! There are about 15 million people living on its 1,991 square kilometres. On average (平均) 7,500 people live on each square kilometre. It is 1,080 more than that in Hong Kong, and nearly 800 more than that in Guangzhou.
Besides, Shenzhen owns 2 million local vehicles (车辆), and about 300,000 vehicles from other places also run on the local roads every day. The total length of the city’s road is 6,041 kilometres. It means each person only owns 0.58 metres of road!
As a result, the city is facing serious environmental and resource (资源) problems. One of the problems is water shortage. The amount of fresh water for each person of the city is only 25% of the country’s average. What’s more, most of the water drunk by Shenzhen people comes from other areas.
