In recent years, riding a hot-air balloon has become more and more popular. Many people practice flying a hot-air balloon as a sport. Some people may question the safety of riding a hot-air balloon. Generally speaking, hot-air balloons are quite safe.
Before examining the safety of hot-air balloons, it may help to understand how they work. Each balloon has a large bag called an envelope, attached to a bag or gondola(吊篮). In order to get enough lift, the air in the bag is heated with the assistance of a flame. As the air heats up, the balloon rises.
Like kites, hot-air balloons travel with the wind. Typically, pilots choose the early morning hours to fly since wind speeds are low. Meanwhile, the flight will become more enjoyable.
High winds and extreme weather such as storm and snow are very dangerous. An experienced pilot will not fly in these conditions. Good pilots always check their equipment before beginning a flight, and they often carry backup for safety even in sunny days.
Riding hot-air balloons can be great fun, and it's very safe as long as passengers follow the directions of the pilot. People who have a fear of heights may want to skip the experience, however.
A. Of course, some people enjoy it as a relaxing activity.
B. Low wind speeds make flying hot-air balloons much safer.
C. This, of course, is for those who love to challenge themselves.
D. The requirements of flying a hot-air balloon vary in different nations.
E. The weather is the most important concern in the safety of hot-air balloons.
F. Sometimes weather, such as lightning, is the cause of hot-air balloon accidents.
G. When the flight is over, the pilot slowly lets out air to allow the balloon to drop.

The man who could see the future
The ability to predict the future is a rare talent. American author Isaac Asimov (1920-1992), one of the great science fiction writers of his age, had such a talent. {#blank#}1{#/blank#} Now that we're here, let's see what he got right.
{#blank#}2{#/blank#} Asimov thought computers would cause a revolution comparable to the industrial revolution of the 19th century. Specifically, he said that "mobile computerized objects" would be an important part of everyday life. Here, he clearly predicted our world of smartphones, tables and other devices. He also had a great deal to say about space exploration. {#blank#}3{#/blank#}
How did Asimov develop his special sense of future developments? {#blank#}4{#/blank#} He read the newspapers and magazines sold in his parents' candy store. His scientific interest gained sharper focus at Columbia University in New York. Asimov went to study chemistry, but became bored with pure laboratory science. Instead, he thought hard about the social implications (作用) of science. He wanted to communicate his ideas to the public.
{#blank#}5{#/blank#} Asimov had his finger on the pulse (脉搏) of both scientific and social change. He had a clear vision of what was coming around the corner for humanity in his works like the Galactic Empire series (《银河帝国系列》). "His predictions are absolutely fascinating," Calum Chase, an English writer, told BBC News. "He was a genius."
