Read the article and select the best answer. Article: London, Reuters--What could annoy teenagers enough to make them stop hanging out with friends and go home? No, it's not a visit from their mothers, and not a threat to take away their cellphones or pocket money. It's high-frequency noise. The UK police recently agreed to use a device called the Sonic Teenager Deterrent. It sends out a sound that makes teenagers become so impatient and angry that they have to cover their ears tightly and walk away. The sound is at extreme high-pitch that can be heard by those under 20. The body's natural ability to detect some wave bands decreases almost entirely after 20, so few adults can hear the sounds. The black-box device, nicknamed the Mosquito because of its sound, can be fixed to the outside walls of shops, offices and homes. It sounds to youngsters like a crazy insect or a badly played violin. But it causes no physical damage. A number of police forces and councils have given permission to use the system and want to install it at trouble spots. Staffordshire Police Inspector Amanda Davies, who has given the device to shopkeepers in the Moorlands area, said," It is controlled by the shopkeepers--if they can see through their window that there is a problem, they turn the device on for a while until the group has run away." Question: The device can be used to _ . Options: A: threaten teenagers in public B: drive away trouble-makers under 20 C: help mothers control their teenage children D: help the police control shopkeepers

Article: The fast development of modern technology has not only provided people with more income, but also enable them to enjoy long weekends and holidays. Never before have so many people traveled to so many different parts of the world and, with the help of fast, comfortable forms of modern transport, more and more people are tempted to leave their homes to see more of the world. It seems as if there are travelers everywhere. People travel because traveling benefits them in a number of ways. First, it enables them to get much pleasure from sight-seeing and photo-taking. Second, traveling makes them fully relaxed and ready to get back to work happily. Third, it offers them an opportunity to visit old friends and make new friends as well. Finally, it allows them to see different customs, learn new things, gain new experience and enables them to come back with a broader mind.

The young man nodded, "Yes. I have been dreaming of being a person as notable as you. Every minute I am thinking of how to become reputable. I don't know when I can achieve my fame (,)." Edison told him, "Don't worry, young man. If you want to be a famous man this way, you will have to wait until you die!" "Why should I?" the young man was puzzled. Edison said, "What you dream is actually a high building. You never think of how to build it with bricks . Thus the building will never come into reality . However, your story can serve as a mirror.
