Global warming happens when greenhouse gases trap heat and light from the sun in the earths atmosphere, which increases the temperature. This is like when heat is trapped in a car. On a hot day, the car gets hotter when it is out in the parking lot. This is because the heat and light from the sun can get into the car, by going through the windows，but it can’t get back out. This is what the greenhouse effect does to the earth .The heat and light can get through the atmosphere, but it can’t get out. As a result，the temperature rises.

Sometimes the temperature can change in a way that helps us. The greenhouse effect makes the earth appropriate for people to live on. Without it，the earth would be freezing，or it would be burning hot. It would be freezing at night because we would not get the sun’s heat and light .During the day, especially during the summer, it would be burning because the sun would be up with no atmosphere to filter(過濾)it，so people，plants，and animals would be exposed to all the light and heat.

Although the greenhouse effect makes the earth able to have people living on it，if there gets to be too many gases，the each can get unusually warmer, and many plants，animals．a(chǎn)nd people will die. Plants would die because they would not be able to take the heat .This would cause us to have less food to eat,and it would also limit the food that animals have. With less food for the animals that we need to survive we would even have less food. Gradually,people，plants，and animals would all die of hunger．

People are doing many things to try to stop global warming .One thing is carpooling—driving with someone to a place that you are both going to. Another thing is being more careful about leaving electrical devices turned on. Now,more people are even riding buses or bikes to lower the amount of greenhouse gases in the air .Although adults do many things to help stop global warming,kids call do just as much.

A. It only traps the heat of the sun.

B. It does great harm to humans.

C. It makes the earth neither too hot nor too cold.

D. It prevents all the light from the sun shining on the earth.

4.What is the main idea of the third paragraph?

A. lf there is greenhouse effect,all the plants will die

B. Human beings are likely to disappear from the earth

C. Crops can’t take in the heat lf there is greenhouse effect

Europe is home to a variety of cultural treasures. Lonely Planet, the world’s largest travel guide publisher, has offered pairs of cities for culturehungry but timepoor travelers.

London and Paris

It takes you about two hours to travel from London to Paris by Eurostar, a high-speed railway service. The two capital cities have been competing in fashion, art and nightlife for decades－but each secretly looks up to the other.

No one can doubt the grand and impressive beauty of Paris' Louvre Museum, but if you want to save money, you cannot skip the British Museum free to visit. Compared with London, Paris has more outdoor attractions such as the beautiful green walkway La Promenade Plantee.

In Paris, you'll see diners linger over red wine. While in London, you can try some afternoon tea, eat fish and chips or salted cake.

Vienna and Bratislava

Austrian capital Vienna and Slovakia city Bratislava are an hour apart by train. But since they are linked by the Danube River, the best way to travel is by ship. A tour of the two cities is the perfect way to experience everything from 17th century’s Habsburg dynasty splendor to scifi restaurants.

Vienna is famous for Mozart and imperial palaces. You can appreciate the perfect blending of architecture and nature in the grand Schonbrunn Palace, and reward yourself with a cup of Vienna coffee, which has made its way to the world's cultural heritage list.

Bratislava is best known for its fine dining－the remarkable UFO restaurant. You can enjoy a meatladen dinner here in an amazing setting.
