In the 19th century, Americans from the eastern states moved out west to settle in the rich new lands along the Pacific Coast. The most difficult part of their trip was crossing “the Great American Desert” in the western part of the United States by horse and wagon.
The western desert can be very dangerous. There is little water and there are few trees. But the desert also has scenery of great beauty. Tall towers of red and yellow stone rise sharply from the flat, sandy valley floor. The scene has been photographed many times and appears in movies and on TV.
In Arizona, man-made dams across the Colorado River have made two large lakes in the middle of the dry desert country. At Lake Powell, the red stone arch of Rainbow Bridge rises high above the blue lake.
There are few roads. Many areas of Lake Powell’s shore can only be reached by boat or on foot. But hikers in this empty desert land sometimes find very old native American pictures, painted on the rocks.
In Death Valley, California, the summer temperature rises to 130°F—165°F. There is less than inches of rain each year. Death Valley is the lowest place in America---925 metres below sea level. In the 1800s, many travelers died when they tried to cross this waterless valley in the terrible heat.
Although the desert is dry and seems empty, there is plenty of life if you look closely. Snakes and rats have learned how to live in the desert heat. They live underground and come out at night, when it is cool. Plants such as cacti need very little water. When it does rain in the desert (sometimes only once or twice a year), plants grow quickly, and flowers open in a single day. For a short time, the desert is covered with brilliant (very bright) colours.In the 19th century, Americans moved from east to west because they .

Can you remember the first time you learned to ride a bike or drive a car？Learning these skills changed your life forever and opened up new horizons（视野）. Learning about computers can be like learning how to ride a bike or drive a car. Once you have invested the time to master the skills，you will never go back to the old days. The new technology is simply too convenient and too powerful.
Technological developments through the years have enabled us to do more with less effort. We have continuously looked for better ways of doing things. Each invention and new development has allowed us to extend our capabilities. Today we see one of the most dramatic technologies ever developed—the computer. It extends the capabilities of our minds.
Computers have saved organizations millions of dollars. Furthermore，these same computer systems have opened up new opportunities that would have gone undiscovered or neglected. The computer may multiply what we can do，and the return on investment is high. The growth of computer usage is surprising. On the other hand，the computer can do serious damage. Invasion of privacy（侵犯隐私），fraud（欺诈），and computer-related mistakes are just a few shocking examples.The computer is like a double-edged sword. It has the ability to cut us free from some activities，but it can also cut deep into profits，personal privacy，and our society in general. How it is used is not a function of technology. It is strictly a function of how people decide to use or misuse this new technology. The choice is yours，and only through a knowledge of computer systems will you be able to avoid the dangers while enjoying the many，many benefits of the computer age.The writer thinks learning about computers is like learning how to ride a bike or drive a car because ______.

Tourism probably started in Roman times. Rich Romans visited friends and family who were working in another part of the Roman empire. But when the empire broke down, this kind of tourism stopped.
In the early 17th century, the idea of the“Grand Tour”was born. Rich young English people sailed across the English Channel. They visited the most beautiful and important European cities of the time, including Paris in France, and Rome and Venice in Italy. Their tours lasted for two to four years, and the tourists stayed a few weeks or months in each city. The“Grand Tour”was an important part of young people’s education—but only for the rich.
In the 18th century, tourism began to change. For example, people in the UK started to visit some towns, such as Bath to“take the waters”.They believed that the water there was good for their health. So large and expensive hotels were built in these towns.
In the 19th century, travel became much more popular and faster. When the first railways were built in the 1820s,it was easier for people to travel between towns, so they started to go for holidays by the sea. And some started to have holidays in the countryside as cities became larger, noisier and dirtier.
Traveling by sea also became faster and safer when the first steamships were built. People began to travel more to far away countries.
The 20th century saw cars become more and more popular among ordinary people. Planes were made larger, so ticket prices dropped and more people used them.
Thus tourism grew. In 1949, Russian journalist Vladimir Raitz started a company called Horizon Holidays. The company organizes everything—plane tickets, hotel rooms, even food—and tourists pay for it all before they leave home. The package tour and modern tourist industry was born.
The first travel agency in China was set up as early as 1949.But tourism did not take off until 1978.In 2002,the industry was worth 500 billion Yuan and became an important part of China’s social development.In the early times, the travelers ________.

________ played the most important role in the tourism development.

Modern tourism was born ________.
| A．in 1949 | B．in Roman times |
| C．in the early 17th century | D．in the 19th century |
The underlined phrase“take off”means ________.
| A．a plane rising into the air | B．develop very fast |
| C．remove hats and clothes | D．bring down the prices |

But Alzheimer’s disease is not confined （限于） to the aged. There may be a million or more people under the age of 65 suffering from the disease.
At one time, people suffering from the disease were said to be“getting old”.The disease was thought to be a natural part of growing old, but it is now known that Alzheimer’s disease strikes young and old alike. It is an organic disease which destroys brain cells.

Scientists don’t know exactly what causes Alzheimer’s disease. It may be caused by a virus.It may be caused by a poisonous substance（物质） in the environment. At present, there is no cure for the disease. But there are ways to slow its progress.
