1970 was "World Conservation Year". The UN wanted everyone to know that the world was in danger - they hoped that governments would act quickly in order to conserve nature. Here is one example of the problem. At one time there were 1,300 different plants, trees and flowers in Holland, but now only remain 860. The others have been destroyed by modern man and his technology. We are changing the earth, the air and the water, and everything that grows and lives here. We can't live without these things. If it continues like this, we shall destroy ourselves.

       What will happen in the future? Perhaps it is more important to ask "What must we do now?" The people who will be living in the world of tomorrow are the young of today. A lot of them know that conservation is necessary. Many are helping to save our world. They plant trees, build bridges across rivers in forests, and so on. In a small town in the United States a large group of girls cleaned the banks of 11 kilometers of their river. Young people may hear about conservation through a record called NO ONE'S GOING TO CHANGE OUR WORLD. It was made by the Beatles and other singers. The money from it will help to conserve wild animals.

    Clean water is not only important for people to produce food, but necessary for our life However, many people in Asia and Africa don't have enough clean water to use The World Health Organization reports that almost 4 000 children die each day of dirty water or lack(缺乏)of water.

    Farmers use 70% - 85% 0f the world freshwater to produce food. People usually don't pay much attention to how much water industry(工业)uses, but you may be surprised to know that industry uses 59% of the water in developed countries.

    Home use takes up（占据）only 8% in the world. But as cities grow, more water will be used. The local government has to try to make people useless water. In 60% of European cities, people are saving water by using less. They even keep waste water for other use. In Australia, the government has encouraged people to collect rainwater and recycle water from showers for a second use, The US Environmental Protection Agency has made a water saving program to encourage families and businesses to check their water use and save more water. Scientists and the UN are looking for good water management as the key to solving the problem. We can all work together to protect our fresh water in our daily life.

    A long time ago, people thought that the Sun went round the Earth. In some countries people even said that the Sun was a god (神). They thought the god drove across the sky each day on a golden horse. Now we know the Earth goes round the Sun. It takes the Earth a year to go all way round the Sun. Today men even know how far it is for the Earth to go round the Sun. They tell us that the Earth travels over a thousand miles a minute on its journey round the Sun.

    The Sun is really a star. It is much bigger than the Earth and it is very hot. Some people have been to the Moon but we know that no one can ever go to the Sun. It is far too hot for people to live anywhere near it. The Sun is about three hundred thousand times heavier than the Earth and more than a million times larger.

    Are you angry by the noise of your alarm clock every morning? Still feel sleepy after getting up? Now, you can say goodbye to that annoying alarm clock, you needn't hear its unpleasant noise every morning.

    The Glow pillow (发光枕)can wake you up with soft LED lights. The lights produce the brightness over 40 minutes just like the sunrise.

The pillow is taking the place of the traditional alarm clock. It was designed (设计)by Eosin McNally and Ian Walton to be against the pressures of a"24 hour "lifestyle.

    The pillow uses a kind of LED material below the surface. It wakes the user up with light. The material can also show the time on the pillow's surface, and it is perfect for those who sleep with their heads completely buried(埋)face down into the pillow. 40 minutes before the pre-set(预设)alarm time, the pillow begins to glow and gently brings the user out of sleep. The natural waking process helps to set "body clock" and makes people build a healthy sleep-and-wake habit slowly.

    When you're closing your eyes and hitting your pillow, you're probably not giving much thought about the sleeping position throughout the night. Most people don't change their sleeping positions throughout their lives. The following is why you might want to pay more attention: Your sleeping position can actually say a bit about who you are and what your personality is like.

    There are many sleeping positions. The fetal (胎儿的) sleeping position is generally the most common sleeping position. Fetal sleepers sleep on their side, they move into a position in which their body makes a rounded shape. People who sleep in the fetal position are often quite sensitive and generally shy. They are often worried or nervous and don't focus their attention on the main problem, but get into trouble on very small pieces of information.

    The log (木头) sleeper rests on the side with a straight body when hands and legs are kept at the sides. These sleepers are often relaxed, but also can easily believe lie-tellers. If you're a log sleeper, you might want to keep in mind that it's good to be easy-going and have less stress, but don't be so quick to go with the flow (流) at all times.

    The third one is the soldier position. Soldier sleepers typically lie on their backs with both arms close to their sides. In general, they are the strong and silent type. However, they can also put the pressure on. "They can be quite strict with themselves as well as others," a scientist added.
