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 (装置) 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 (安装) 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."

1.The device can be used to _______.

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

2.From the passage we can know that _______.

A．young people often suffer from pains in ears

B．shopkeepers are troubled by noisy insects

C．high-frequency noise is beyond the listening ability of people over 20

D．the police invented a new device to deal with teenagers

3.The purpose of the writer to write the passage is ______.

A．to advertise a new hi-tech device

B．to tell the reader a piece of news

C．to sell the device to shopkeepers

D．to inform the public as the spokesman of the police

4.Who will welcome the device most?

A．Shopkeepers.      B．The police.         C．Young people.      D．The producer.

Don’t be surprised when strangers talk to you in Canada! You will find that many Canadians will smile at you as they pass in the street, or say something to you like “Hi!” or “How’s it going?” Just reply with something similar. In the UK the reply would be “I’m fine”, but in Canada they say “I’m good”.
In company, when someone is offering you a second helping of food or more wine, if you don’t want any more, use the same expression— “I’m good”. In this case, it means “No, thank you. I’ve had enough”. Most Canadians don't press you to eat more than you want.
In restaurant, your plate will be cleared away almost immediately you have finished eating. When you go into a shop or store, the shop assistant asks you how you are or if they can help you, it is their way of being friendly and making conversation with the customers.
Canadians eat early and go home early. When you are invited to a Canadian’s home, you may be asked to arrive at 5:30 pm or 6 pm. But guests in Europe don’t expect to arrive until 7:30 pm or 8 pm. Remember to take off your shoes and leave them inside the door without being asked. It’s not a religious custom, but it’s practical. In winter, there can be a lot of snow and dirt on your shoes, once you are in the warm house it melts and falls off, making a mess. Canadians tend to have light colored carpets or hardwood floors.
If you’re invited for dinner, it will be a full sit- down meal. Meat is usually barbecued in the freezing cold of winter. Do take something with you, like a bottle of wine. Arrive on time and don’t stay over 10 pm.
1. Which of the following statements is NOT true according to the passage?

  The playwright George Bernard Shaw once said humorously, “England and America are two nations divided by a common language. If he were writing today, he might add ‘divided by a common technology--- e-mail’”.

  Two completely different styles of e-mail have formed on either side of the Atlantic-Euromail and Amerimail. Americail is informal and chatty. It’s likely to begin with a “Hi” and end with a “Bye”. The chances of Amerimail containing a smiley face or an “xoxo” are disturbingly high. We Americans are unwilling to dive into the meat of an e-mail. We feel we have to first inform recipients (收信人) about our vacation on the island which was really excellent except the jellyfish were biting and the kids caught a cold, so we had to skip the whale watching trip, but about that investors’ meeting in New York. Amerimail is a bundle of contradictions, casual and yet direct, respectful yet over proud. In other words, Amerimail is America.

  Euromail is stiff and cold often beginning with a formal “Dear Mr. X” and ending with a simple “Sincerely”. You won’t find any mention of kids or the weather or jellyfish in Euromail. It’s all business. It’s also slow. Your correspondent might take days even weeks to answer a message. Euromail is exactly like the Europeans themselves.

  Recently about 100 managers were asked on both sides of the Atlantic whether they noticed differences in e-mail styles. Most said yes. Here are a few of their observations:

  “Americans tend to write (e-mail) exactly as they speak.”

  “Why don’t you just call me instead of writing five e-mails back and forth?”

  “Europeans are less interested in checking e-mail”.

  “In general, Americans are much more responsive to e-mail—they respond faster and provide more information.”

  So which is better, Euromail or Amerimail? I realized it’s not popular these days to suggest we have anything to learn from Europeans, but I’m fed up with an inbox filled with casual, barely meaningful e-mails from friends and colleagues. If the alternative is a few earnestly written, carefully worded bits of Euromail, then I say, “Bring it on.”

What did George Bernard Shaw mean by saying “England and America are two nations divided by a common language”?

A. There is not much difference between British English and American English.

B. Both England and America speak the common language, so they are much the same.

C. Either England or America is a divided nation, though they share a common language.

D. There is sharp difference between England and America despite their common language.

Which of the following is most likely to be the “meat” of an Amerimail?

A. The jellyfish were biting.

B. We had an excellent vacation on the island.

C. We had to skip the whale watching trip.

D. We were to attend the investors’ meeting in New York.

On receiving an e-mail, Europeans tend to __________.

A. respond to it immediately and earnestly

B. take more time than Americans to respond to it

C. respond by calling up their correspondent

D. never respond to it all

What are characteristics of Amerimail?

A. Informal and chatty                                          B. Casual and indirect

C. Stiff and cold                                                       D. Formal and direc60

We can conclude from the passage that __________.

A. the different e-mail styles do much harm to the relationship between the two sides on Atlantic

B. Amerimail is more appreciated by the writer for being informative and casually written

C. Euromail always impresses the writer as something more pleasant to read

D. the writer doesn’t favor either e-mail style as both have their own shortcomings
