Builders have known for many years that white roofs reflect(反射) sunlight and lower the cost of air conditioning (空調(diào)設(shè)備). But now scientists say they have found a new advantage: slowing global warming.
Hashem Akbari believes that whitening 100 of the world’s largest cities could make the influence of the expected emissions (排放物) smaller over the next ten years.
White buildings and surfaces reflect far more sunlight than dark ones. Reflected sunlight does not increase the greenhouse effect (溫室效應), unlike the heat energy sent out by dark surfaces heated by the sun.
Dr Akbari, of the Lawrence Berkeley National Laboratory, California, also argues that If built-up areas were made white, less heat would stay within them, allowing people to use their air conditioners less, which use a lot of power.
Dr Akbari has found out that making 100 of the largest cities white would increase the sunlight reflected by Earth by 0.03%. He believes it would cancel out (抵消) the warming caused by 44 billion tons of carbon (碳) emissions.
“Roofs are going to have to be changed one by one and to make that effort at a very local level, we need to have an organization to make it happen,”says Dr Akbari.
He argues that while the action would not solve the problem of climate change. it would slow it.
“We can give the environment time to breathe,” he says. “I just don’t see a disadvantage of this idea. It gives everybody advantages and you don’t have to make hard efforts to make it happen. ”
Akbari and his partners say they will try to persuade the United Nations to organize big cities to change the materials of their roofs.
How do white roofs slow down global warming?
A. They reflect sunlight, which makes people use no air conditioner.
B. They reflect sunlight, which doesn’t increase the greenhouse effect.
C. They keep the heat energy within them.
D. They send out no carbon emissions.
We know from Dr Akbari that he .
A. has changed some roofs into white ones
B. doesn’t use air conditioners himself
C. has built an organization to make cities white
D. believes his idea will help slow the climate change
What do Akbari and his partners want to do?
A. They hope the UN will put their idea into action.
B. They want to become members of the UN.
C They want to change the materials of their own roofs.
D. They want to teach people how to change roofs
The passags is written mainly to .
A. persuade people to paint their roofs white
B. introduce environment friendly paint
C. show white roofs do good to the environment
D. discuss how to slow down global warming

From school to band Practice, the Venturi Eclectic is an Earth-friendly way to get where you want to go. This battery-powered, zero-emission (meaning it doesn't pollute the air) vehicle runs mainly on renewable energy. Solar panels on the Eclectic's roof absorb sun rays when you're driving. On windy days, you can connect a machine to the car's roof that collects energy from the wind while you're parked. The Eclectic's top speed is 28 miles an hour; the battery lasts for 31 miles before it needs to be recharged. Zipping (迅速行進) around the neighborhood has never been better.
Here's an eco-friendly way to tell time: Simply fill the Bedol Water-powered Clock's tank (箱) with water, add some lemon juice, and the clock will display the time without the need for environmentally harmful batteries. There are two sets of metal electrodes (電極) inside the water tank. Water contains ions (離子) that carry negative and positive charges. These ions complete a charge between the electrodes, creating enough energy to power the clock. Just refill the tank every few weeks, and this clock will keep on ticking.
Bloodhound SuperSonic Car (SSC) will be the first car to attempt to break the l,000-mile-an-hour barrier. (The current record is 763 miles an hour.) A concept for now, the rocket-shaped car gets its original push to 350 miles an hour from a jet engine. Then a rocket fires up, pushing the SSC past 1,000 miles an hour. In order to keep the car streamlined (流線型的), the driver lies back at a 45-degree angle (角度).
You’re having a blast at your friend’s birthday party. But when it's time to bring out the cake, everyone crowds around, blocking your view. No worries. Throw the Triops into the air, and this clever camera captures the view from above. The Triops can take three pictures at once, each from different angles. You can also record sounds and command the Triops to start shooting whenever it hears that noise. That's one smart camera.
What is the common characteristic of the Venturi Eclectic and the Bedol Water-powered Clock?
A. They don't need batteries. B. They are difficult to operate.
C. They can be powered by water. D. They are environmentally friendly.
According to the passage, the Venturi Eclectic .
A. is popular with businessmen B. is suitable for a long trip
C. can turn wind into energy D. has only a little gas emission
The underlined phrase “having a blast” in the last paragraph probably means .
A. looking at a picture B. enjoying yourself
C. blowing out a candle D. recording sounds
Which of the following is TRUE according to the passage?
A. The Triops is sensitive to sounds.
B. The driver of the SSC must be of great size.
C. The color of the Bedol Water-powered Clock is like that of lemon.
D. The SSC doesn’t have anything to do with a rocket actually.

The “Bystander Apathy Effect” was first studied by researchers in New York after neighbors ignored—and in some cases turned up the volume on their TVs—the cries of a woman as she was murdered (over a half-hour period). With regard to helping those in difficulty generally, they found that:
(1) women are helped more than men;
(2) men help more than women;
(3) attractive women are helped more than unattractive women.
Other factors relate to the number of people in the area, whether the person is thought to be in trouble through their own fault, and whether a person sees himself as being able to help.
According to Adrian Furnham, Professor of University College, London, there are three reasons why we tend to stand by doing nothing:
(1) “Shifting of responsibility”-the more people there are, the less likely help is to be given. Each person excuses himself by thinking someone else will help, so that the more “other people’ there are, the greater the total shifting of responsibility.
(2) “'Fear of making a mistake'’-situations are often not clear. People think that those involved in an accident may know each other or it may be a joke, so a fear of embarrassment makes them keep themselves to themselves.
(3) “Fear of the consequences if attention is turned on you, and the person is violent.”
Laurie Taylor, Professor of Sociology at London University, says: “In the experiments I’ve seen on intervention (介入), much depends on the neighborhood or setting. There is a silence on public transport which is hard to break. We are embarrassed to draw attention to something that is happening, while in a football match, people get involved, and a fight would easily follow. ”
Psychotherapist Alan Dupuy identifies the importance of the individual: “The British as a whole have some difficulty intervening, but there are exceptional individuals in every group who are prepared to intervene, regardless of their own safety: These would be people with a strong moral code or religious ideals.”
Which of the following statements is true according to the passage?
A. Pretty women are more likely to be helped.
B. People on a bus are more likely to stop a crime.
C. Religious people are more likely to look on.
D. Criminals are more likely to harm women.
Which factor is NOT related with intervention according to the passage?
A. Sex. B. Nationality. C. Profession. D. Setting.
Which phenomenon can be described as the “Bystander Apathy Effect”?
A. When one is in trouble, people think it’s his own fault.
B. In a football match, people get involved in a fight.
C. Seeing a murder, people feel sorry that it should have happened.
D. On hearing a cry for help, people keep themselves to themselves.
