On Nov.18th,1908,three men went up in a balloon（气球）.They started early in London. The headman was Augusta Gaudron, and the other two men were Tannar and Maitland. They had a big balloon and they were ready for a long way.

    Soon they heard the sea. They were carrying the usual rope（绳子）,and it was hanging down from the basket of the balloon. At the end of the rope they had tied a metal box. This could hold water, or it could be empty. So they were able to change its weight. It was for use over the sea. They were also carrying some bags of sand.

    After the sun rose, the balloon went higher. It went up to 3,000 meters, and the air was very cold. The water in the balloon became ice. Snow fell past the men's basket, and they could see more snow on the ground. The men tried to throw out some more sand; but it was hard. They tried to break the icy sand with their knives, but it was not easy. The work was slow and they were still falling, so they had to drop some whole bags of sand. One of them fell on an icy lake and made a black hole in the ice.

    At last they pulled the box into the basket. It was still snowing, so they climbed to get away from the snow. They rose to 5,100 metres! Everything became icy. They were so cold that they decided to land. They came down in Poland heavily but safely. They had travelled 1, 797 kilometers from London!

Welcome to the farm! I'm a tomato seed. Here are steps to plant me. 

Today, people want to keep healthy through sports and exercise. But some of them have some wrong ideas about it. "A plate of chicken is a good meal before games because it has much energy."

In fact, the best meal before games should have carbohydrates（碳水化合物）. Food like potatoes, bread, bananas are rich in it, but chicken and meat are not.

"The best time to exercise is early in the morning."

No. Morning is a good time to exercise, but it may not be suitable for you. If an afternoon or evening is suitable for you, and you enjoy the feeling of getting healthier, you can choose any time to exercise. So there is no fixed time for you to exercise.

"If you drink water when you exercise, you'll feel tired."

The fact is that you must have some water during breaks（休息时间）when you exercise. And after exercising, you must have enough water. If you don't drink enough water, then you may feel tired.

"Exercising every day is quite important."

Wrong. Too much exercise is bad for your health. You need to give your body a day of rest.
