A green house is a building made of glass which is used for keeping warm when the outside temperature is low. In a similar way there are several gases in the atmosphere (mixture of gases that surround the earth) which trap the heat produced by the sun and prevent it from escaping. These gases are known as “greenhouse gases”. and the way in which they trap heat in the atmosphere is called the “greenhouse effect”. This is not simply air pollution. Most of the main greenhouse gases exist naturally in small amounts in our atmosphere, and without them the earth would be 30 degrees colder and human life would not exist. In other words, the greenhouse effect is a natural course which is to some degree helpful to us.

The problem is that in the last century and a half, we have been putting too many of these gases into the earth’s atmosphere by burning large quantities of coal and oil and by cutting down forest. The rapid increase in greenhouse gases is making the world warmer. The world’s temperature has already gone up by half a degree this century, and the sea level has risen by 10 centimetres. If the amount of carbon dioxide in the atmosphere doubles, there will probably be a rise in the earth’s temperature of between I and 4℃;. This may seem a small increase, but it would be enough to cause major changes in geography and agriculture. Large areas of the world would be flooded, and some areas would become dry and unable to produce crops. It is important, too, to consider that there may be a delay of about 30 years in the greenhouse effect. This means that we are probably experiencing only now the effect of the gases put into the atmosphere before the 1960s. Since then, our use of these gases has greatly increased.

When traveling abroad, it is wise to carry your money in traveler's checks because checks are protected against loss or theft. If your checks are lost or stolen, the issuing authority will refund(赔偿) your money.

Not only are they safe, they are also convenient. They are available in different currencies and they can be cashed at most banks throughout the world. Most shops, hotels and restaurants also accept them.

Traveler's checks are very easy to use. When you collect them, you sign each check once. The cashier enters the amount in your passport. When you cash, you sign each check again. The cashier will usually ask to see your passport again too.

To get traveler's checks you usually go to your bank. They can be paid in cash or in other ways. Large amounts, however, must be ordered in advance.

For the safety and convenience of traveler's checks, you are charged two commissions(佣金，酬劳): an insurance commission when you buy them and an encashment commission when you cash them.

It is suitable to make a note of the serial numbers of your checks. Keep this separate from your traveler's checks.
