Never try to work when you are very hungry. If you decided to do your homework right after school, you may get something to eat before getting to work. Always do your homework before you get too tired. Don't wait until very late in everything, or your work will seem much harder than it really is.

    If you have more than an hour's work, give yourself a break after an hour. On the other hand, don't break it up so much, or you can't finish anything, you should be able to work at least a half at a time without stopping.

    Don't put it off until the last minute. If you put off doing your homework, you will have it on your mind, and you will not enjoy your free time so much. If you put it off until the end of the week or until right before a test, you will have too much work to do. A little bit each night, enough to keep up with what is happening each day in school, will make you not afraid of the test and get good grades.

Do your homework at the same time every evening. This will help you make it a habit. It will make it easier to do, and it will make your free time more enjoyable, as well.

    In Britain, people usually begin their talks with weather. For example, they will say“It's a fine day, isn't it?”“Do you think it will rain?”

    Many people believe that they are able to tell what the weather will be like. But they never agree with each other. One man may say, “How cloudy (阴的) it is now! It's going to rain.” Another man will say, “No, it's going to be fine later.”

    People always hope the weather they want. For example, when a farmer needs water, he looks for something to tell him it's going to rain. When a man wants to travel, he is sure the weather will be fine quickly.

    Now almost everyone listens to the weather report. It doesn't always tell us the weather we want, it only tells us what the weather will be like. But sometimes it makes mistakes(错误).

    People in India call New Year "Diwali" or "the Festival of Light(光)".

They often clean their houses before the day of Diwali. Most people clean their houses in the morning. They often decorate their houses with flowers. They also make sweet food look like flowers, people and animals. Then they visit their friends and give them presents and cards.

    On New Year's Day, many people open the doors and windows and light(点亮) candles in front of the doors. They want to bring good luck to their families. After Diwali, people often dean their houses again. Some people like to make loud noises at their houses. They think this can make bad spirits(幽灵} go away.

Many people take running as a way to keep fit. They like to run in hot weather and enjoy the feeling of being wet through with sweat (汗) while running. Cold weather during winter months, with low temperatures and freezing cold winds, may keep people from running in the open air.

However, a new study shows that the drop in temperature is a good reason to run. In fact, running in cold weather helps improve one's performance. Many runners might find it easier to run in winter than in hot weather. The body needs less water on a cold day than in warm weather. In addition, lower temperatures reduce stress on the body. When you run in cold weather, your heart rate is lower.

John Brewer is a professor of applied sports science at St. Mary's University in London. For this study, he and other researchers put a group of people into a room where summer and winter weather conditions are recreated. The test subjects were asked to run 10,000 meters under both conditions and their biological measurements were recorded and studied.From the study, every movement runners make produces heat. The heat can be really damaging unless the body can lose it. One way in which people lose heat is by sweating. The body loses heat through sweat. The body also loses it by transporting the blood to the surface of the skin and it puts more stress on the heart, especially in hot conditions because it's much harder to lose heat when the outside environment is warm. As the result shows, running in hot temperatures results in 6 percent higher heat rates.

When running in cold conditions, the body does not have to work hard to move blood to the skin surface. Therefore, it requires less energy. The most important thing for people who run in cold conditions is to wear the right clothing. Keep as dry as possible when exercising in low temperatures. Wear warm and light clothing to keep sweat away from your skin. So don't let winter weather keep you indoors. Simply get ready for the low temperatures and start running.
