Online shoppers would rather receive an offer for a product or service than make their own offer 3 according to a study led by a Michigan State University scholar that has implications for the fast-growing e-commerce industry. The findings may come as a surprise given that shopping online is an anonymous(匿名的)process that seemingly can give consumers more confidence to drive a hard bargain,said Don Conlon ,Professor of Management in MSU’s Broad College of Business.
But the study found that participants who made their own offers were less successful in sealing the deal and ,when they were successful? worried they overpaid Many shoppers found the process of researching an offer to be a hassle. “ Americans are very busy,and it’s less time-consuming to be the one receiving the offer rather than the one proposing the offer  ” Conlon said. u People tend to be happier when they’re in the receiver role. ”
Online spending in the United States is expected to jump 45 percent in the next four years, from數學公式327 billion in 2017,according to Forrester Research Inc. Nevertheless, researches into this prosperous market remain largely focused on the strategies of companies, rather than those o? shoppers. Conlons study is ,obviously, a rare exception.
Conlon got the idea for the study after considering the difference between two popular sites for hotels and airline flights, priceline.com, which takes bids, and hotwire.com ,which provides offers. Using these two models ,Conlon and his fellow researchers conducted a series of experiments with more than 850 people who were charged with booking a fictional hotel room and acquiring a fictional antique car. Not only did participants prefer to receive bids, Conlon said ,but they also secured more deals in that receiver role. Further ,when they had to make the bids ,they were left more mentally taxed and regretful.
From an industry perspective,putting customers in the receiver role may help fill more hotel rooms and airplane seats. “If you’re a business with a lot of products3 ” Conlon said,“you may want to be the one making the offers. ” However, when selling single items, such as an antique car, accepting bids may be a better option since that typically drives up the price, he said

Scientists know of more than 1,000 volcanoes on the surface of Venus, Earth’s “sister” planet. A big question has been: Are they still active? The scientists say yes.
Their evidence for recent volcanic activity on Venus comes from a lava(熔巖) flow in the planet’s northern hemisphere. The flow is hotter than the rocks around, which means the lava might still be cooling off. “The flow we studied seems to be very young---it is still warm inside,” Nataliya Bondarenko said.
Venus is a difficult planet to study from Earth because it is surrounded by thick clouds. Telescopes on Earth can’t see through these clouds, so the best information about Venus comes from spacecraft orbiting it.
Bondarenko and her colleagues studied the lava flow using data from NASA’s Magellan mission. That spacecraft spent four years in orbit around Venus and used radar to make a map of 98 percent of the planet’s surface. On October 11th, 1994, the mission ended, and the spacecraft plunged (跌落) through Venus’ heavy cloud cover and crashed onto the planet below.
While in orbit, the Magellan craft sent microwaves, which can go through Venus’ clouds, to the surface. Microwaves are invisible and can be as long as three feet. These waves are a kind of energy, like light. And like light, they bounce off surfaces. The way the waves bounced off the Venus’ surface and back to the craft supplied information that the scientists used to estimate the temperature of various parts of the planet’s surface. Bondarenko’s team found that the lava flow was hotter than its surroundings---which may mean the lava flow is in the process of cooling.
The scientists say the lava flow can’t be very old because if it were, it would have cooled off enough that Magellan wouldn’t have noticed the difference in microwaves. She adds that the flow appears in a 1978 view of the surface that a craft called the Pioneer Venus Orbiter captured

  1. 1.

    What happened to Magellan in the end?

    1. A.
      It was floating in space forever
    2. B.
      It flew into heavy clouds
    3. C.
      It returned to the Earth
    4. D.
      It fell onto Venus
  2. 2.

    How could Bondarenko judge the temperature of the Venus?

    1. A.
      By looking at it with a powerful telescope
    2. B.
      By measuring the thickness of clouds over Venus
    3. C.
      By calculating the microwave bouncing off Venus’s surface
    4. D.
      By orbiting Venus for 4 years in a spacecraft
  3. 3.

    The best title for the passage may be “______ ”

    1. A.
      Warm lava on Venus
    2. B.
      More volcanic eruptions on Venus
    3. C.
      Venus is just like a big active volcano

The porter(行李搬運工) brings your bags to your room and helpfully explains all you want to know.Then he points to the phone and says:“If there’s anything else you need, just call.”All this time you have been thinking of one thing:“How much should I tip(付小費)him?” To make your next trip a little easier, here’s guide to tipping across some Asian countries.
Bangkok(曼谷)
In general, the more westernized the place is, the more likely you will be expected to leave a tip.Some top-end restaurants will add a 10% service charge to the bill.If not, waiters will appreciate your tacking on(附加)the 10% yourself.However, if you’re eating at a lower-end restaurant, a tip is not necessary.If you’re staying at one of Bangkok’s many five-star hotels, expect to tip the porter 20 to 50 baht(泰國貨幣單位),depending on how many bags you have.Taxis are now metered in Bangkok.Local custom is to round up(湊整數)the fare to the nearest five baht.
Hong Kong
Tipping is customary in this money-mad metropolis(大都市).Most restaurants add a 10% service charge to the bill, but the extra money often ends up in the pocket of the owner. If the service is good, add another 10% to the bill, up to HKMYMl00 in an especially nice restaurant.For HK MYM10 hotel porters should do it at all but the nicest hotels where a new HKMYM20 bill may be more acceptable.When in a taxi, round up to the nearest dollar.
Kuala Lumpur(吉隆坡)
Tipping in Malaysia is limited to the expensive westernized hotels, which often add a 10% service charge to your meal or hotel room.If you are at a hotel restaurant, expect a 10% service charge.
But at local restaurants, there’s no need to add a tip. At five-star hotels, one or two ringgit(馬來西亞貨幣單位)will satisfy a porter. At lower-end buildings don’t feel you have to tip Like Bangkok, many taxis are now metered so you can just round up to the nearest ringgit.
Seoul
Tipping is not part of Korean culture, although it has become a matter of course in international hotels where a 10% service charge is often added.If you’re at a Korean barbecue joint(燒烤處), there’s no need to add anything extra.But a nice Italian restaurant may require a 10% contribution.
If you’re at a top-end hotel, so expect to pay 500~l,000 won per bag.Taxi drivers don’t accept a tip.Keep the change for yourself.

  1. 1.

    Which of the following is NOT the unit of money?.

    1. A.
      Charge
    2. B.
      Baht

      Bangkok
    2. B.
      Hongkong
    3. C.
      Kuala Lumpur
    4. D.
      Seoul
  3. 3.

    If you stay at a five-star hotel in Kuala Lumpur, how much will you pay the porter at least?

    1. A.
      10% of service charge
    2. B.
      Three ringgit
    3. C.
      Half a ringgit
    4. D.
      One ringgit
  4. 4.

    The writer seems           

    1. A.
      to tell the readers how to travel

      to give the readers some advice on how to tip

“Slow City” — a recently launched project focused on preserving the traditional quality of life enjoyed in some of Italy’s smaller cities and towns. The project was born from the idea of the “Slow Food” movement — started in Italy in the 1980s — which promotes leisurely eating and the growing of local, healthy products to fight against the American fast-food style.
“The American urban model has invaded our cities, making Italian towns look the same. We want to stop this kind of globalization,” says Paolo Saturnini, an Italian mayor.
The “Slow City” project plans to emphasize the rich, cultural, culinary(廚房的) and artistic local traditions of each community.
Walking areas will be enlarged and squares and parks will be made greener with more plants. Car alarms and other noise that disturbs the peace will be banned, and ugly TV aerials(天線), advertising posters, and signs will be taken down.
City councils will also insist on the use of recycling and renewable energy sources, and will also introduce ecological transport systems. Parking will be made stress-free by creating more public parking areas, and easily accessible walkways and bike lanes will cross the city. But in the “Slow City” way, all improvements will probably come about slowly.
Thirty-two Italian city councils, which joined the “Slow City” program, have decided to take further steps in this direction by increasing the numbers of traditional family-style eating establishments, reducing noise pollution, and concentrating on making their towns friendlier for people to live in.
Organic local produce will be promoted in all restaurants and genetically modified foods(轉基因食品) will be banned. “We can’t stop large, fast-food chains from coming here, but we hope that people who come to our towns will not want to eat exactly the same hamburger they can eat in Melbourne, London or Paris, but want something genuine and different,” said Saturnini

  1. 1.

    According to the passage, the “Slow City” project aims at _____

    1. A.
      preventing Italy from being affected by America
    2. B.
      beautifying the environment of small Italian cities and towns
    3. C.
      calling on Italians to enjoy stress-free life
    4. D.
      protecting the traditional Italian lifestyle
  2. 2.

    From Paragraphs 4-5, we can infer that ______

    1. A.
      cars in “Slow City” will have to go slowly
    2. B.
      people can park their cars free of charge in “Slow City”
    3. C.
      “Slow City” will take on an environmentally friendly look
    4. D.
      advertising in “Slow City” will be banned
  3. 3.

    Further measures will be included in the “Slow City” program EXCEPT _____

    1. A.
      cutting down noise pollution
    2. B.
      stop genetically modified foods
    3. C.
      getting more towns involved in the project
    4. D.
      building more family-style restaurants
  4. 4.

    In Saturnini’s opinion, when traveling in “Slow Cities”, visitors_____

    1. A.
      aren’t provided with fast food
    2. B.
      will see few fast-food chains
    3. C.
      can enjoy themselves like in London
    4. D.
      can enjoy real Italian-style healthy food

China_is_going_green. In order to reduce air pollution and oil­shortages, automobile manufacturers have announced their plans to develop hybrid vehicles (混合燃料汽車) for the Chinese market. Toyota's hybrid car Prius will be ready to drive in China this week. Let's have a look at the new car.
Any vehicle is a hybrid when it combines two or more sources of power. Hybrid cars run off a rechargeable battery and gasoline. Hybrid cars have special engines, which are smaller than traditional gasoline engines. They run at 99 percent of their power when the car is cruising (勻速行駛). A specially designed battery motor provides extra power for running up hills or when extra acceleration is needed.
Step into a Prius, and turn on the engine. The first thing you notice is how much quieter it is than a traditional car. At this point, the car's gasoline engine is dormant (休眠). The electric motor will provide power until the car reaches about 24 km/h. If you stay at a low speed, you are effectively driving an electric car, with no gasoline being used, and no waste gas gives off.
The onboard(車載的) computer makes the decision about when to use a gas engine, when to go electric, and when to use a combination of the two. If you go over 24 km/h, when you step on the gas pedal (油門), you are actually telling the computer how fast you want to go.
The electronic motor recharges automatically using a set of batteries. When driving at high speed, the gasoline engine not only powers the car, but also charges the batteries. Any time you use the brake, the electric motor in the wheels will work like a generator and produce electricity to recharge the batteries. As a consequence, the car's batteries will last for around 200,000 miles

      The hybrid cars reduce air pollution and oil­shortages
    2. B.
      The car's gasoline engine doesn't work until it reaches about 24 km/h
    3. C.
      This kind of car is completely controlled by an onboard computer
    4. D.
      A specially designed battery motor provides extra power when needed

    What is the most important feature of hybrid cars?

    1. A.
      They are powered by both a rechargeable battery and gasoline
    2. B.
      They are much quieter than traditional cars
    3. C.
      They only use 99 percent of their power to run up hills

Dear Mayor,
I would like to draw your attention to the depressing state of the environment in our city. Increased vehicles have made the air polluted. Citizens find it difficult to breathe. Dumping toxic chemicals into the river has polluted the drinking water and ground water.
All of us, as concerned citizens, have discussed these problems in various meetings. We have come up with the following proposals(提議).
The green roads are no longer green. Many trees and bushes have been cut. We propose restricting the movement of vehicles. Besides, we should make it compulsory(強制性的)to use anti-pollution devices on all vehicles. We should also plant more plants and trees along roads.
The Bada Nadi River has become a dumping ground of toxic chemicals from some factories. These toxic chemicals have killed nearly all the life in the river and polluted our drinking water and ground water. We propose that the Bada Nadi River be declared a protected water body. All the dumping should be banned and heavy fine should be imposed on the offenders(違法者). To tackle the problem of managing toxic waste, we propose setting up a water treatment plant so that only clean water is discharged into the river. Cleaning up the river and introducing various fishes and plants to the river will bring it back to life.
Lastly, the noise pollution caused by honking(鳴)horns and blaring loudspeakers has caused distress to one and all. Many people have suffered from noise-related illnesses. We propose a blanket ban on the use of loudspeakers. And“no horn zones”should also be declared in residential hospitals and school areas.
I would request you to seriously consider our proposals and act accordingly.
Thank you!
Sincerely yours,
A kind-hearted citizen
