Many companies use guards and expensive alarm systems to protect their property(财产)。 Soon a new kind of protection will be used- robots. Engineers have been working on the first mobile robots for businesses. The robots will patrol(巡逻) factories, warehoues(仓库)，and museums at night.
The mobile robots will move around slowly on wheels. They will be able to detect people through walls and pick up sounds, such as breaking glass. They can be fixed with lound sirens(警笛) to frighten thieves, or radios to signal police or guards.
To protect a building, a robot will have to move around without knocking into the walls. Information about the building will have to be stored in the robot’s small, built-in computer. A floor map could be programmed into the computer’s memory, for example.
A mobile robot will not be able to do everything. Unlike human guards, it will not be able to climb stairs, open doors, or move along rough ground. It won’t be able to tell the difference between friends and enemies. Because of that, people will have to be barred from the area it patrols.
One kind of mobile robot will be able to “sense” whether a chair or box has been moved and go around it. This robot will also judge size well enough so that it won’t send an alam if a cat crosses the room. And if someone tries to steal this robot, it will sound a loud, painful siren. The three-foot-tall robot will be hard to steal anyway. It will weigh about 200 pounds.
U.S companies pay almost $10 billion a year to protect their property with alarm systems and human guards. Mobile robots may be cheaper.Why is the new kind of robots called mobile robots?
| A．Because they are able to climb stairs. | B．Because they are able to send an alarm |
| C．Because they can open doors. | D．Because they can move around slowly on wheels |
How will a robot get directions for moving around a building?

| C．From another robot . | D．From radio signals. |
What does the underlined word barred mean?
| A．protected | B．allowed . | C．marked | D．prevented |

| A．sense whether something has been moved. | B．sense a cat crossing the room. |
| C．move over rough ground . | D．detect people through walls. |
This text mainly describes how robots will ___________.

Once a year, a race is held for old cars. A lot of cars entered for this race last year and there was a great deal of excitement just before it began. One of the most handsome cars was a Rolls-Royce Silver Ghost. The most unusual car was a Benz which had only three wheels (车轮). Made in 1885, it was the oldest car taking part in the race. After a great many loud explosions, the race began. Many of the cars broke down on the course and some drivers spent more time under their cars than in them.
A few cars, however, completed the race. The winning car reached a speed (速度) of forty miles an hour — much faster than any of its rivals. It sped (加速前进) downhill at the end of the race and its driver had a lot of trouble trying to stop it. The race gave everyone a great deal of pleasure. It was very different from modern car races but no less exciting.

During the cold winter days you may find it hard to wake up in the morning. It’s warm and cozy (舒适的) in your bed.
In winter, many animals like to sleep, too. But their sleeps can be very long and deep. This kind of sleep is called hibernation (冬眠). During this kind of sleep, their temperatures go down, and hearts beat (跳动) slowly. They take very small breaths(呼吸).
Animals can hibernate for part or all of the winter. It’s hard for them to find things to eat. When they go to sleep, they don’t need much food.
Bears, hedgehogs (刺猬) and chipmunks (花栗鼠) go to sleep in their homes. Frogs(青蛙) and snakes hibernate, too. Frogs move into the earth under water to keep themselves warm.
Before they go to sleep, they eat a lot to get fat (脂肪). Some also keep food in their homes to eat later.
Bears are the biggest animals that hibernate. They often sleep in caves (山洞). Bears must eat a lot of things like nuts before going to sleep for a long time. They eat as much as 300 apples ( that’s the same as 60 hamburgers) each day for many weeks. They can eat for 20 hours in a day!
Bears can go into a very deep sleep. It can last from three months to half a year. During that time they do not eat, drink or go to the toilet. A mother bear can give birth to babies during her hibernation.
Other animals sleep less. Sometimes they wake up to eat, or take a walk. Then they go to sleep again.

It is not easy to find a public place without advertisements. We can see them everywhere, especially in newspapers or on TV. It’s true that ads are playing a more and more important part in our daily life. They tell us some information about new products and help us to decide what to buy.
‘Each coin has two sides’-----Everything has its advantages and disadvantages(优势和劣势).Ads also have disadvantages. For example, some of the factories hope to win a big market for their products. They are so dishonest that they don’t tell the truth about their products. They try their best to make people believe that the advertised（打广告的）products are good. But in fact they are of poor quality(质量). Many people are cheated(欺骗) by the dishonest ads. So people often buy what they do not need.Where can ads be seen(被看到)?
______________________________________________What does an ad help us to do?
