How do you think of the following example? Many Japanese never take the vacations they should enjoy, but with the coming of “Golden Week”, several holidays following one after another in late April and early May, they pour out of the country in the tens of thousands.

   So when traveling, whether on business or for pleasure, the first thing to think about are hotels. The kind of hotel you choose is decided according to how much money you want to spend. There are small hotels with very few services, where the prices are low, or there are large hotels with all the very latest comforts, where you could spend all the money you have in the bank for a very comfortable night.

   There are several different kinds of people who go to hotels. Some want to live, rather than just stay, in a hotel; hotels which are designed to meet their needs are called residential hotels. However, most people who stay in hotels are either business people or tourists on holiday.

   In most hotels, there are two kinds of rooms: single rooms, for the use of one person, and double rooms, for the use of two people. In addition, in large hotels, there are also suites (套房), which include two or more rooms connected together — perhaps a bedroom and a living room. They are for people who are very rich or very important.

1.From the example of many Japanese, we can learn that           .

A. they don’t enjoy taking vacations because it’s too expensive

B. they enjoy touring in “Golden Week” because it consists of several holidays

C. they don’t have vacations unless they go abroad

D. they enjoy staying at home unless they have enough time and money

2.A person’s choice of a particular hotel is made mainly according to           .

A. how much he is willing to pay for a night

B. whether he is traveling on business or for pleasure

C. whether the hotel is in the central part of a city

When you think about math, you probably don’t think about breaking the law, solving mysteries or finding criminals. But a mathematician in Maryland does, and he has come up with mathematical tools to help police find criminals.
People who solve crimes look for patterns that might reveal (揭示) the identity of the criminal. It’s long been believed, for example, that criminals will break the law closer to where they live, simply because it’s easier to get around in their own neighborhood. If police see a pattern of robberies in a certain area, they may look for a suspect who lives near the crime scenes. So, the farther away from the area a crime takes place, the less likely it is that the same criminal did it.
But Mike O’Leary, a mathematician at Towson University in Maryland, says that this kind of approach may be too simple. He says that police may get better clues to the location of a criminal’s home base by combining these patterns with a city’s layout (布局) and historical crime records.
The records of past crimes contain geographical information and can reveal easy targets — that is, the kind of stores that might be less difficult to rob. Because these stores are along roads, the locations of past crimes contain information about where major streets and intersections are. O’Leary is writing a new computer program that will quickly provide this kind of information for a given city. His program also includes information about the people who live in the city, and information about how a criminal’s patterns change with age. It’s been shown, for example, that the younger the criminal, the closer to home the crime.
Other computer programmers have worked on similar software, but O’Leary’s uses more math. The mathematician plans to make his computer program available, free of charge, to police departments around the country.
The program is just one way to use math to fight crime. O’Leary says that criminology — the study of crime and criminals — contains a lot of good math problems. “I feel like I’m in a gold mine and I’m the only one who knows what gold looks like,” he says. “It’s a lot of fun.”

They’re faithful, friendly and furry-but under their harmless appearance, dogs and cats, the world’s most popular house pets, use up more energy resources in a year than driving a car, according to a new book

In their book Time to Eat the Dog: The Real Guide to Sustainable（可持续的） Living, New Zealand-based architects Robert and Brenda Vale say keeping a medium-sized dog has the same ecological impact as driving 10,000 km a year in a 4.6 liter Land Cruiser. "There are no recipes in the book," Robert Vale said, laughingly, in a telephone interview. "We’re not actually saying it is time to eat the dog. We’re just saying that we need to think about and know the ecological impact of some of the things we do and that we take for granted."

Constructing and driving the jeep for a year requires 0.41 hectares of land, while growing and manufacturing a dog’s food takes about 0.84 hectares. Meat-eating swells the eco-footprint of dogs, and cats are not that much better, the Vales found. Thus, they recommend keeping "greener", smaller, and more sustainable pets, such as goldfish, chickens or rabbits.

The book’s playful title, and serious suggestion that pet animals should be usefully "recycled", by being eaten by their owners or turned into pet food when they die, may not appeal to animal fans.

Offputting as the idea may be, the question is valid, considering the planet’s growing population and limited resources, Robert Vale said.

"Issues about sustainability are increasingly becoming things that are going to require us to make choices which are as difficult as eating your dog. It’s not just about changing your light bulbs or taking a cloth bag to the supermarket," he said. "It’s about much more challenging and difficult issues," he added. "Once you see where cats and dogs fit in your overall balance of things, you might decide to have the cat but not to have the two cars and the three bathrooms and be a meat eater yourself."

A. show their interest in driving a car

3. According to the Vales, ______

A. people are encouraged to keep a medium-sized dog

B. people are supposed to eat dogs at once

C. animal fans are willing to turn their pets into food

D. people are advised to keep more sustainable pets

A. unpleasant    B. acceptable     C. reasonable     D. satisfactory

5. The last paragraph shows that______

A. the writer shows little interest in changing the light bulbs

B. it’s challenging for people to live a sustainable life

C. people shouldn’t keep pets as well as a car meanwhile

D. it’s necessary for pet owners to eat their lovely dogs
