In a few years, most people will know that a healthy, happy, loving family is a joy and it is a necessary part for building a strong society. But there are still some people who don’t believe family life can be an enjoyable experience.
Some people already accepted the idea of the “me generation” so they fail to understand that there is a time in life when they have to give up their time to something more valuable.
At a time when adults need to think about the needs of their family, they will be doing other important things. Some people will spend too much time working for a more powerful car or a bigger house so that they can proudly say that they have them. Some will be doing dangerous things so that they may tell their stories to their friends, and others will recite things like “ I must become the best I can be.”  or “I don’t want to be at the bottom.” The needs of their family will be forgotten and they never seem to have time for the family.
Many people have not experienced a strong helpful perfect family life, so they have never discovered its worth. Many people have always experienced family life as a flight, so they can’t find time and energy for work.

Right in the middle of the town are some long ponds(水池). They are only about half a foot deep. The men of Symi dug out the earth to make the ponds.
Over each pond is a low cover. It is made of glass that you can see through.
At night, sea water is taken into the ponds. The next day, the hot sun shines through the covers. The sun light turns the water into vapor(水蒸氣) and the vapor goes up from the ponds. The salt is left behind.
As it goes, the vapor became mist. On the inside of each cover, the little drops of mist run together to make big drops. These drops run down the sides of the cover, filling other ponds with fresh water.
The salt left in the ponds is washed out each night. Then more sea water is taken in. The factory is ready for the next day’s work. The covers and other parts of the factory cost very little.

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 (包裝), 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(有機的) cotton, which is grown without the use of pesticides ( 殺蟲劑).
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.
小題1:The underlined phrase "a vintage store" in this passage refers to (是指) a place where you can buy          .
