题目列表(包括答案和解析)

Imagine you’re at a party full of strangers. You’re nervous. Who are these people? How do you start a conversation? Fortunately, you’ve got a thing that sends out energy at tiny chips in everyone’s name tag (标签). The chips send back name, job, hobbies, and the time available for meeting-whatever. Making new friends becomes simple

This hasn’t quite happened in real life. But the world is already experiencing a revolution using RFID technology.

An RFID tag with a tiny chip can be fixed in a product, under your pet’s skin, even under your own skin. Passive RFID tags have no energy source-batteries because they do not need it. The energy comes from the reader, a scanning device, that sends out energy (for example, radio waves) that starts up the tag immediately.

Such a tag carries information specific to that object, and the data can be updated. Already, RFID technology is used for recognizing each car or truck on the road and it might appear in your passport. Doctors can put a tiny chip under the skin that will help locate and obtain a patient’s medical records. At a nightclub in Paris or in New York the same chip gets you into the VIP (very important person) section and pays for the bill with the wave of an arm.

Take a step back:10 or 12 years ago,you would have heard about the coming age of computing. One example always seemed to surface: Your refrigerator would know when you needed to buy more milk. The concept was that computer chips could be put everywhere and send information in a smart network that would make ordinary life simpler

RFID tags are a small part of this phenomenon. “The world is going to be a loosely coupled set of individual small devices, connected wirelessly,” predicts Dr.J.Reich. Human right supporters are nervous about the possibilities of such technology. It goes too far tracking school kids through RFID tags, they say. We imagine a world in which a beer company could find out not only when you bought a beer but also when you drank it. And how many beers. Accompanied by how many biscuits. w*w*When Marconi invented radio, he thought it would be used for ship-to-shore communication. Not for pop music. Who knows how RFID and related technologies will be used in the future. Here’s a wild guess: Not for buying milk.

1. The article is intended to______.  

A. warn people of the possible risks in adopting RFID technology

4. Why are some people worried about RFID technology?

A. Because children will be tracked by strangers.

B. Because market competition will become more fierce.

C. Because their private lives will be greatly affected.

D. Because customers will be forced to buy more products.

5. The last paragraph implies that RFID technology        .

A. will not be used for such matters as buying milk

B. will be widely used, including for buying milk

C. will be limited to communication uses

D. will probably be used for pop music

Your cellphone holds secrets about you.  Besides the names and numbers that you’ve programmed into it, traces of your DNA remain on it, according to a new study.

DNA is genetic material that appears in every cell. Like your fingerprint, your DNA is unique to you - unless you have an identical twin. Scientists today usually analyze DNA in blood, saliva (唾液)or hair left behind at the scene of a crime. The results often help detectives identify criminals and victims.

Meghan J. McFadden, a biologist at McMaster University in Hamilton, Ontario, heard about a crime in which the suspect bled onto a cellphone and later dropped it. This made her wonder whether traces of DNA remained on cellphones - even when no blood was involved. To find out, she and a colleague collected flip-style (翻盖式)phones from 10 volunteers. They collected invisible traces of the users from two parts of the phone: the outside, where the user holds it, and the speaker, which is placed at the user’s ear.

The scientists cleaned the phones using a liquid mixture made mostly of alcohol. The aim of washing was to remove all detectable traces of DNA. The owners got their phones back for another week. Then they returned the phones and the researchers collected traces on each phone once more. They discovered DNA that belonged to the phone’s owner on each of the phones.

Surprisingly, DNA was even picked up immediately after the phones were cleaned. That suggests that washing won’t remove all traces of evidence from a criminal’s cellphone. So cellphones can be added to the list of clues that can settle a crime-scene investigation.

64. In a crime-scene investigation, now experts are likely to turn to ________.

A. the criminal’s fingerprint             B. the DNA analysis of physical items

C. the detectives                      D. the criminal’s cellphone

65. According to the passage, McFadden was inspired by ________.

A. the secrets stored in people’s cellphones   B. the special characters of DNA

C. a cellphone-involved case             D. the challenging job of detectives

66. According to the passage, the potential application of the new study would be ________.

A. identifying criminals         B. designing new cellphones

C. protecting individual privacy    D. preventing cellphone-involved crimes

67. Which of the following has the closest meaning with the underlined word “identify” in Paragraph 2?

A. imagine       B. recognize         C. discover          D. determine

出国游有许多需要注意的事项。而付小费是很多国家的普遍现象。由于文化习俗的差异,不同的国家、不同的地区做法不尽相同。以下A、B、C、D、E和F是对亚洲一些城市给付小费的介绍,选出符合编号描述的选项。选项中有一项是多余选项。

1. Most expensive restaurants will add a 10% service charge to the bill.

2.Though tipping is not allowed, people who have served you accept tips in a certain way.

3.Culturally, tipping is unnecessary, but customers sometimes pay service charge when checking out.

4. If you want to get loyal service, you should give a tip more than 10%.

5.You ae not expected to pay tips at a low class hotel.

A

Bangkok (曼谷) There are no established rules of tipping in Bangkok, capital of Thailand. Some places expect it; others don’t. In general, the more westernized the place is, the more likely you’ll be expected to leave a tip.

   Restaurants: Some expensive restaurants will add a 10% service charge to the bill. If not, waiters will appr eciate your increasing by 10% yourself. However, if you’re eating at a cheap eatery, a ti is not necessary.

   Porters: At Bangkok’s many five-star hotels, you’re expected to tip the porter 20 to 50 baht(铢), depending on how many bags you have.

   Taxis: Taxis are now metered in Bangkok, so there’s no bargaining over your fare. The local custom is to round the fare up to the nearest five baht.

 B

Jakarta (雅加达)  Tipping is not part of the Indonesian culture, but international influences have turned some westernized palms upward in search of a few extra rupiah (卢比).

   Restaurants: A 10% service charge is added at most high-end restaurants. At moderately priced restaurants, 5,000 rupiah should do it---if the service is superb, add an extra 1,000 rupiah or so.

   Porters: Pay a few hundred rupiah for each bag.

   Taxis: Most drivers will automatically round up to the next 500 rupiah. Some will claim they have no change and will bleed you for more. Don’t accept anything more than a 1,000-rupiah increase.

C

Kuala Lumpur (吉隆坡)  Like Indonesia, tipping in Malaysia is only common in the expensive westernized joints, which often add a 10% service charge to your meal or hotel bill.

   Restaurants: If you are at a hotel restaurant, expect a 10% service charge or add the same amount yourself. But at local stalls, there’s no need to add a tip.

   Porters: At five-star hotels, one or two ringgit(林吉特) will be enough. At low-end establishments, you are not forced to tip.

   Taxis: Many taxis are now metered, so you can just round up to the nearest ringgit. In unmetered taxis, expect a session of hard bargaining for the ride.

D

Manila (马尼拉)  Tipping is common in Manila, the Philippines, and anything above 10% will gain you long-lasting loyalty.

   Restaurants: Even if a service charge is included, it is a custom to add another 5%-10% to the bill.

   Porters: Service in top hotels is good and should be rewarded with 20% pesos(比索) per bag.

   Taxis: Most taxis are metered, and rounding up to the next five pesos is a good rule of taking taxis.

E

Seoul   Tipping is not part of the Korean culture, although it has become a rule in international hotels where a 10% service charge is often added.

   Restaurants: If you are at a Korean barbecue (烧烤店), there’s no need to add anything extra. But a luxury Italian restaurant may require a 10% service charge.

   Porters: If you are at a top-end hotel, international standards apply, so expect to tip 500-1,000 won per bag.

   Taxis: Drivers don’t expect a tip, so unless you’re feeling remarkably generous, keep the change for yourself.

F

Singapore City   According to government rules in the Lion City, tipping is a no-no. It’s basically outlawed at Changi Airport and officials encourage tourists to neglect the 10% service charge that many high-end hotels add to the bill.

   Restaurants: Singaporeans tend not to leave tips, especially at the outdoor eateries. Nicer restaurants do sometimes charge a 10% service fee, but there’s no need to supplement that.

   Porters: Hotel staff are the one exception to the no-tipping rule. As a general guide, S$1 would be enough for baggage-lugging service.

   Taxis: Drivers don’t expect tips, but they won’t refuse if you want to round up the fare to the next Singaporean dollar.
