It’s important to learn about protecting our environment. Here is a 5R rule for us:
1. Reduce
If you want to reduce waste, you should use things wisely. Millions of trees are being cut down to make paper. If everyone uses a little paper carelessly and throw it out, soon we would not have any trees left. Other things are also being wasted, and people don’t know what to do with the waste in big cities. So it is necessary to reduce the waste
2. Reuse
You should always think of reusing the usable things before throwing them out. Give your clothes you do not use or the ones which are too small to the poor. With a family, you may pass on such clothes to younger brothers or sisters.
3.  Recycle
Bottles, cans and paper can easily be recycled. By doing so, we save lots of time and money. For example, coke cans are sent to a factory, where they are smashed flat（压平）and melted (融化) and the melted things are made for new coke cans.
4.  Recover
When you buy a box of apples, there may be a few rotten（腐烂的）apples. You have two choices: one is to throw the whole apple away, or you could cut off the rotten parts and eat the good parts. In this way, you are recovering the eatable parts of food.
5.  Repair
If one of the legs of your table is broken, you can repair it instead of throwing it away. If you want to change for better ones, It is better for you to sell the old things or give them to other people who can use them after doing some repair. It is true that North America is a “throw-away” society（社会）. But the time has come to change our way of life so that we can protect our environment. Every one of us should try our best.

It is said that the eyes are the windows of our soul. Beautiful and bright eyes not only show a good health but also make you look very attractive. However, to have healthy eyes you have to look after them properly. Your eyes need everyday attention.
Pay more attention to your diet. First, eat food that is good for your eyes. They are fresh fruits and vegetables as fish, eggs, and milk. Besides, a regular amount of vitamins A and B2 should also be taken.
A regular and sound sleep is a must. It relaxes the eye muscles（肌肉）and gives them the rest required. Sleep not only helps the body to repair its tired tissues (组织). Usually, you must sleep for at least seven to eight hours every day. Loss of sleep can give you dark circles under the eye.
You must exercise your eyes every day. Blink (眨眼) yours eyes at regular periods, which makes the eyeballs watery, and gives them a good wash.
We use our eyes in many unnoticeable and wrong ways. Fox example, if a small thing goes into our eye we start rubbing it, which is wrong. Rubbing can cause damage（伤害） to your eyes. Don’t read or write in poor or bright sunlight. Always use sunglasses as sunlight can cause eye tiredness. Light should not shine directly in your eyes. Too much reading, writing, watching television or working on the computer can also cause eye tiredness.
Remember to always take care of God’s most beautiful gift to you. Your life will be very colorless without your eyes.

It began with a red paper clip and ended with a house. Kyle MacDonald, a 26-year-old Canadian, got a three-bedroom house through 14 trades (交换) that started with a single red paper clip.
Encouraged by Kyle’s successful experience, now more and more young people around the world are starting their own trading activities. They set up websites where people can trade things they don’t usually use with other people. A website called Peerflix allows people to trade their used DVDs. These traders usually prefer face-to-face trading, which means they don’t have to worry about who is going to pay for the delivery (递送).
Last year, a young girl in Beijing decided to follow the example of Kyle. She started with a paper clip and hoped to get a house in the end. After several trades she now has a piano which is more than 10,000 yuan. But she may still have a long way to go.
You may be puzzled about why people are doing this. In fact, everyone in the trade activities gets things that are useful to them. Just as Kyle said, “What’s more important to a man dying of thirst in the desert — one million dollars or a glass of water?” Kyle’s words probably show why these trades are poplar among young people.
