To understand why the Earth is warming up, first of all, we need to understand why it is warm. Our planet is covered with atmosphere(大气).Sunlight passes through the atmosphere and reaches the Earth. The Sun heats up the Earth's surface. When the heat rises into the air, it is stopped by some special gases in the atmosphere like CO2, the heat returns to the Earth and keeps it warm.

Power stations and cars release so many green-house gases every day. So we can help stop global warming by using less electric things such as turning off lights when we leave a room, asking our parents to turn down the heating in our house to save energy. We can also stop global warming by finding other ways of transportation. For example, ride a bicycle or walk instead of going by car. Another way to help stop global warming is to plant and care for trees. Because trees take in C02 , they are our best friends when fighting against global warming.

The problem of global warming cannot be solved in a day. It may take a long time to find clean energy, such as wind energy. It may take a long time to plant the trees again which were cut down. But every little thing each person can do to save energy and our forests will help. Think about our planet. Think about ways we can help make the Earth a safe and comfortable place for the future.

My first photo was taken at the age of 9.While I couldn't even remember the model of the camera,I do remember the enjoyment of looking through the photos.

When I was 16 years old,I bought a Canon camera before an overseas trip. Over the years I took many photos with it. There's Aunt Sarah,smiling in front of Buckingham Palace; Aunt Sarah,smiling under the Eiffel Tower; and Aunt Sarah,smiling in a Venetian Canal. Everyone knows what Aunt Sarah looks like. They also know what Europe's great landmarks(显著地面景观) look like. I didn't think about composition(构图) when taking the photos.

After the camera was stolen,I didn't buy one for a long time because I didn't want to buy a camera that I work difficulty until I found a Vivitar Series camera. It worked well in natural light,and I took a lot of photos with it. From then on,I had an artist's eye. My pictures were not of familiar Greek architectures. Instead,I took pictures of farmers at work in the field,fishermen repairing their nets. I captured(抓住) the color and character of the country. My friends were so interested that they asked for more.

Happiness is for everyone. You don't need to care about those who have beautiful houses with large gardens and swimming pools or 1.and so on. Why? Because those who have big houses may often feel lonely and those who have cars may want to walk on the country roads at their free time.

In fact, happiness is always around you if you put your heart into it. 2.When you study hard at your lessons, your parents are always taking good care of your life and your health; when you get success, your friends will say congratulations to you; When you do something wrong, people around you will help you to correct it.3. All these are your happiness. If you notice them, you can see that happiness is always around you.

Happiness is not the same as money. It is a feeling of your heart.
