Climate is the average weather usually taken over a 30-year time period for a particular region and time period. Climate is not the same as weather, but rather, it is the average pattern of weather for a particular region. Weather describes the short-term state of the atmosphere (大气).
The climate is changing. Many agreed that climate change may be one of the greatest threats (威胁) facing the planet. Recent years show increasing temperatures in various regions, and/or increasing extremities (极端性) in weather patterns.
Is the Earth getting warmer? Yes! The Earth has warmed by about 1°F over the past 100 years. But why? Well, scientists are not exactly sure. The Earth could be getting warmer on its own, but many of the world’s leading climate scientists think that things people do are helping to make the Earth warmer.
Global Warming may be a big problem, but can you make a difference? Yes! There are several little things you can do to make a difference. Try carpooling. This will help reduce the amount of fossil fuels going into the atmosphere. Whenever you use electricity, you help put greenhouse gases into the air. Turn off lights, the television, and the computer when you are through with them. Also, planting trees is fun and a great way to reduce greenhouse gases. Trees absorb carbon dioxide, a greenhouse gas, from the air. Finally, don’t forget about recycling.

We know that trees are useful in our everyday life. They 1 us many things, such as wood, oxygen(氧气), rubber, medicines and many other things. They can 2 tell us a lot about our climate. The following are the reasons. If you cut across a tree, you can 3 that it has many rings. Most trees grow one 4 ring every year. Because of this reason, we know 5 a tree is. A tree over a hundred years old means that it has more than a hundred 6 . When the climate is dry(干燥的) or very cold, the trees do not grow very much and their rings are usually 7 . When it is wet and 8 , the rings are much thicker. If the rings are suddenly very thin or suddenly very thick, this means that the 9 changed suddenly. If we look at the rings on the trees, we can 10 about the climate for a hundred years. We can see how our climate is changing today.

Canada, the second largest country in the world, lies in the north of America. The population of Canada is about 29 million and the capital is Ottawa. The country covers about 9,980,000 square kilometers and six of the world’s 24 time areas (时区) as well.

There are two official languages spoken in Canada: French and English. Many people can speak both English and French. More than 60% of Canadians speak English as their language. About 25% of the Canadians speak French. In one province of Canada where French is the common language, the programmes on TV and radios as well as the teaching in schools are all in French. Today, Chinese has become the first inofficial(非官方的) language in Canada.

Canada’s climate is not as cold all year around as some may believe. In winter, temperatures fall below freezing point throughout most of Canada. In summer, the southern provinces often experience high levels of temperatures that can reach over 30℃ regularly. The weather in Canada is just like the weather in China. It is rather cold in the north while it is fairly warm in the south. Winters in the north last long with snow for half a year. As the cold northern climate, only one-fifth of the land is suitable for farming.

As it is known to all, Canada has one-third of the world’s supply of fresh water. It has many great lakes. There are five great lakes in the south. And there are many others, especially in the north. It is also rich in natural resources, such as coal, oil, natural gas of which Canadians make use to produce energy.

People of northern Canada are called Inuit (因纽特人), who came from Asia and settled in Canada about 4,000 years ago. They used to travel around from place to place with teams of dogs which pulled their baggage. Now, they seldom move. There are about 2,500 Inuit in all. The government has started a new school project in which Inuit teach their own young children. So it is hoped that the way of Inuit life will be kept alive for more centuries.

We know that trees are useful in our everyday life. They give us 1 things, such as wood, oxygen, rubber（橡胶）, medicines 2 many other things. They can also tell us a lot about our climate. The following are the reasons. If you cut 348 a tree, you can see that it has many rings. Most trees grow one new ring 4 year. Because of this, we know how old a tree is. A tree over a hundred 5 means that it has more than a hundred 6 . When the climate is dry or very cold, the trees do not grow very much and their rings 7 usually thin. When it is wet and warm, the rings

8 thicker. If the rings are suddenly very thin or suddenly very thick, it means that the 9 changed suddenly. If we look at the rings on the tree, we can learn about the climate in the past years. We can see
