Our children and grandchildren may not have a chance to visit many of the most famous places around the world. War, weather, age, traffic and pollution damage (破坏) these famous places. If we do nothing, they may even no longer remain. But looking after these places often costs more than one country can afford.

    In the early 1970s, world governments decided that if they joined together, they would be able to preserve (保护) our history. If every country paid some money, they said, it would be possible to look after important historic places. For this reason, countries around the world united to form the World Heritage Organization in 1972. Today, the organization helps to protect and rebuild the most important places from our history.

    However, one of the biggest problems for historic places is vandalism. That is to say, people sometimes enter these places and damage the buildings. At some places, such as Stonehenge in England, governments have built high fences to protect it from vandals.

    There are many different ideas about how to solve the problem of vandalism. Some professors say that if guards keep walking around these places, vandals won't be able to get in. Some professors say that if they fix more television cameras, they won't need so many guards. Others say that the best way is education. If people learn to respect history, they won't damage it. They will also want to spend money looking after old places. For this reason, the World Heritage Organization helps to spread information about the value of historic places.

    There will be a kind of new cars in the future．People will like this kind of small cars better than the big ones．The car is as small as a bike．But it can carry two people in it．Everybody can drive it easily，just like riding a bike．Even children and old people can drive them to schools or parks．

    If everyone drives such cars in the future，there will be less pollution in the air．There will be more space for all the cars in cities，and there will also be more space for people to walk in the streets．

    The little cars of the future will cost less money to buy and to drive．These little cars can go only 65kilometers an hour，so driving will be safer．The cars of the future will be fine for going around the city，but they will not be useful for a long trip．

    This kind of cars can save a lot of gas（汽油）．They will go450kilometers，and then they have to stop for more gas．They are nice cars，aren't they？

It's not WASTE until it is WASTED

    With the World Environment Day coming, our school is now requiring every student to form a habit of sorting the waste.

    Here in our schoolyard we lay four different colors of rubbish bins for different kinds of rubbish. The red is for harmful waste; the blue is for waste that can be recycled(循环再用); the green is for kitchen waste; the yellow is for other waste.

    The following are some instructions for you

    Glass: Empty bottles without caps can be recycled to make new glass bottles.

    Warning: Mirrors and light bulbs(电灯泡) must not be included in the glass waste.

    Paper: Newspapers, magazines, boxes must be clean enough to be recycled.

    Warning: Paper tissues (餐纸) and wall paper are not recyclable as paper and should be kept separately.

    PMD waste: Packaging made of Plastic or Metal and Drink boxes are used to make new packaging.

    Warning: Plastic pots(e. g yoghurt pots ), plastic bags must not be included with the PMD waste.

    Harmful waste: out-of-date drugs, used batteries(电池)， paint and oil…

    Besides, if you don't need your old bikes at all, our school volunteers will collect them. We're going to fix them up and then give them away to kids who don't have enough money for a bike.

    To find out more about recycling, you can visit our school website.

    We want to explore and try to better understand the world in which we live; Space exploration is one of the ways. Through the exploration of space, we can begin to unravel the mysteries of our universe, and to better know our living environment.

    Space exploration provides us with knowledge about the beginning of our solar system, our own planet and ourselves. It also helps answer the questions that have puzzled us for many years. Solar system exploration is important because it is good for us.

    Space technology has become an important part of our daily lives. Some technology uses satellites to communicate. Satellites are also used to examine the changes in the Earth's climate and seas, for weather report and for military. We also use satellites in food production. Because of the use of space technology in crops, fewer and fewer people will suffer hunger.

    The space program provides a chance for nations to work together. The cooperation(合作) promotes peace and understanding between governments and their people. Many governments have taken part in the space technology, including the United States, Russia, Japan, the European nations and India. In the near future, other nations will take part in it. In fact, the United States remains the leader in new space technology.

    Trees are useful to man in three important ways: they give him wood and other useful things, they give him cool places, and they help to stop drought and flood.

    Unluckily, in many parts of the world, man has not found that the third of these points is the most important. Man wants to make money from trees, so he has cut them down in large numbers, only to find that without them he has lost the best friends he had. And also, he is usually too careless to plant and look after new trees. So the forests slowly disappear.

    This does not only mean that man will have fewer trees. The results are even worse: for where there are trees, their roots break up soil make the rain in——and also bind the soil, thus stopping it from being washed away easily; but where there are no trees, the rain falls on hard ground and flows away, causing floods and carrying away the rich top-oil. When all the top soil is gone, nothing is left but useless desert.
