It’s not a particular brain region that makes someone smart or not smart. Nor is it the strength and speed of the connections throughout the brain or such features as total brain volume. Instead, new research shows, it’s the connections between very specific areas of the brain that determine intelligence.
“General intelligence actually relies on a specific network inside the brain, and this is the connections between the gray matter, or cell bodies, and the white matter, or connecting fibers between neurons(神经元)，”said Jan Glascher, lead author of a paper appearing in this week’s issue of the Proceedings of the National Academy of Sciences.
The results weren’t entirely unexpected, said Keith Young, vice chairman at Texas A﹠M Health Science Center College of Medicine in Temple, but “it proves that good communication between various parts of brain are very important for this general intelligence.”
“People noticed a long time ago that, in general, people who are good test-takers did well in a lot of different subjects,”explained Young. “If you’re good in mathematics, you’re also usually good in English. Researchers came up with this idea that this represented a kind of overall intelligence.”
Hoping to learn more, some experts located 241 patients who had some sort of their lesions (损害). They then diagrammed the location of their lesions and had them take IQ testes. “We took patients who had parts of their brain damaged, tested them on intelligence to see where they were good and where they were bad, then we connected those scores across all the patients with the location of the brain lesions,”Glascher explained. “That way, you can know the areas that are associated with reduced performance on these tests, which means these areas are really important for general intelligence.”
“These studies suggest results based on the absence of brain tissue (组织),”added Paul Sanberg, famous professor and director of the University of South Florida Center. “It allows them to systemize and find areas important to intellingence.”

Buses are celebrating their 100th anniversary. About 80 percent of all public-transport passengers worldwide are carried by buses.
The bus is a very efficient mode of transport, being cheap, flexible, comfortable and, in many cases, tailored to the needs of users both in terms of capacity and speed. Buses operate in mixed traffic, and are easy to put in service.
From an economic, environmental and social point of view, the bus remains the best solution to the problem of achieving balanced and environmentally-friendly urban development. Indeed, the bus is the only mode of public transport in many of the world’s cities, and plays a key supporting role in cities with rail transport.
Over the past decades, increased use of roads by private cars has contributed to terrible traffic problems, affecting the speed of buses as well, and hence their service quality, reliability, energy consumption, and economy. In such circumstances, the efficiency and performance of buses depends heavily on special lanes. Various forms are possible----from a mere painted mark on the road to more expensive variants such as elevated lanes, movable barriers, and “bus locks”.
A related trend is to look beyond vehicle technology alone and to consider the wider system, of which buses are a part, such as the infrastructure(基础设施)and other operational aspects of city. This is commonly known and promoted as the “bus-system approach”. Other key innovations(革新) include clean engines, alternative fuels, and guidance devices. In terms of the designs of buses, much of what has happened to light rail can be transferred to them, including the shapes of the vehicles themselves.
The energy consumption of a bus per passenger is one-sixth that of a car, and buses are only responsible for about 5% of the CO2 emissions generated by vehicles at present.
1. From this passage we learn that_____________.
A. buses are the most environmentally-friendly of all motorized vehicles
B. buses were first used more than a century ago
C. most passengers prefer trains to buses
D. a bus has a much larger capacity than any other vehicle
2. What has affected the service quality of buses?
A. Unsuitable infrastructure. B. Private cars.
C. The increasing population of cities.
D. Very rapid urban development.
3. Which of the following is an approach to improving bus service?
A. Improving the speed of buses.
B. Reducing the number of private cars.
C. Setting up special lanes for buses.
D. Increasing the number of buses.
4. From the passage we can infer that in the future_____________.
A. there will be more buses than today
B. bus engines will need no power
C. buses will be replaced by other means of transport
D. the appearance of buses will change

Camp memories last forever! We make sure they are unforgettable!
Shadow Ridge Summer Camps offer so many exciting things for campers to do. Unlike other camp programs that include horses as a small part of their program, at Shadow Ridge horses ARE, the program! We are 100% horse from stable(马厩)management, nature walks, and track rides to bedroom furnishings.
Horses help us achieve many of our aims. Girls can learn to develop responsibility, self-confidence and personal connections in their lives while having fun. Using horses as a wonderful tool for education, our camps offer an interesting place for growth and learning.
Imagine each girl having her very own horse to spend time with and a best friend to love and take care of. Each camper is responsible for a horse for the week. Our riding program provides a lot of riding and lesson time. Campers will learn how to take care of the horse and the tack(马具), as well as how to ride. Days are filled with horse-related activities to strengthen the connection between each girl and horse, as the girls learn to work safely around the horses.
At Shadow Ridge we try to create a loving, caring family atmosphere for our campers. We have “The Bunkhouse”(4 girls), the“ Wranglers Roost”(4 girls), and “The Hideout”(2 girls)in our comfortable 177-year-old farm house. All meals are home cooked, offering delicious and healthy food for the hungry rider.
Our excellent activities create personalized memories of your child's vacation, Each child will receive a camp T-shirt and a photo album (usually 300-500 pictures) of their stay at camp.
Our camps are offered during June, July and August 2007, for small groups of girls aged 13-16 years, not only from Canada but also other parts of the world.

第三部分：阅读理解（共20小题；每小题3分，满分60分）
阅读下列短文，从每题所给的四个选项（A、B、C和D）中，选出最佳选项。
One of the most wonderful things about having a positive attitude is that it can touch many people in the course of everyday life.
Recently I stopped by a store to get a newspaper and a bottle of juice. The young woman at the check-out counter said, “That’ll be three dollars in all please.”She then glanced down at the paper I was buying and said, “I’m sick and tired of all the negative material on the front pages. I want to read some good news for a change.”She then said, “In fact, I think someone should publish a Good News newspaper——a paper with wonderful, inspirational stories about people overcoming difficulties and doing good things for others. I’d buy one every day!”She then thanked me for coming in and said, “Maybe we’ll get lucky tomorrow; maybe we’ll get some good news!”We both laughed, and I thought: she just made my day.
The following day after work I dropped by the same store again to pick up bottled water and a newspaper; but a different young lady was behind the counter. As I checked out I said, “Good afternoon”, and handed her my money . she said nothing, and didn’t smile or make a gesture. She just handed me my change and said in a bored voice, “Next!”
It hit me right between the eyes. Two people, the same age; one had made me feel great , while the other had made me feel that I had inconvenienced her by showing up.
The choices we make and attitudes we show influence lives every day in positive or negative ways. So every morning you should ask yourself:“Who do I want to be today—‘The Grouch(不高兴的人)’or ‘The Good News Girl’?”Your answer will go a long way toward determining the quality of your life and that of those around you.

Europeans should try to stay indoors if ash from Iceland's volcano starts settling, the World Health Organization warned Friday as small amounts fell in Iceland, Scotland and Norway.
WHO spokesman Daniel Epstein said the microscopic(微小的) ash is potentially dangerous for people when it starts to reach the Earth because inhaled(吸入) particles can enter the lungs and cause respiratory problems. And he also said Europeans who go outside might want to consider wearing a mask.
Other experts, however, weren't convinced the volcanic ash would have a major effect on peoples' health and said WHO's warnings were "hysterical." They said volcanic ash was much less dangerous than cigarette smoke or pollution. Volcanic ash is made of fine particles of fragmented volcanic rock. It is light gray to black and can be as fine as talcum powder. During a volcanic eruption, the ash can be breathed deep into the lungs and cause irritation even in healthy people. But once it falls from a greater distance — like from the cloud currently hovering above Europe — its health effects are often minimal, experts say.
"Not all particles are created equal," said Ken Donaldson, a professor of respiratory toxicology at the University of Edinburgh, "In the great scheme of things, volcanic ash is not all that harmful." And he said most Europeans' exposure to volcanic ash would be negligible and that only those in the near districts of the Icelandic volcano would likely be at risk.
Dr. Stephen Spiro, a professor of respiratory medicine and deputy chair of the British Lung Foundation, said the further the particles travel, the less dangerous they will be. "The cloud has already passed over northern Scotland and we haven't heard of any ill effects there," he said. Spiro said to wear masks or stay indoors to avoid volcanic ash was "over the top" and "a bit hysterical."
