At Dallas/Fort Worth Airport, the lights are controlled by sensors that measure sunlight. They dim immediately when it’s sunny and brighten when a passing cloud blocks the sun.
A wall of windows at a University of Pennsylvania engineering building has built-in blinds (百叶窗) controlled by a computer program that follows the sun’s path. Buildings are getting smarter and the next generation of building materials is expected to do even more.
Windows could catch the sun’s energy to heat water. Sensors that measure the carbon dioxide breathed out by people in a room could determine whether the air conditioning needs to be turned up.
Many new materials and technology have been designed in the last 15 years. They are now being used in a wave of buildings designed to save as much energy as possible. They include old ideas, like “green roofs”, where a belt of plants on a roof helps the building keep heat in winter and stay cool in summer, and new ideas, like special coating for windows that lets light in, but keeps heat out.
As technologies such as sensors become cheaper, their uses spread.
The elevators (电梯) at Seven World Trade Center, which is under construction in New York, use a system that groups people traveling to nearby floors into the same elevator, thus saving elevator stops. People who work in the building will enter it by swiping (刷) ID cards that will tell the elevators their floor, readouts will then tell them which elevator to use. The building also has windows with a coating that blocks heat while letting in light.

British researchers have found that children’s IQ predicts their probability of becoming vegetarians (素食者) as young adults.

Recent studies suggest that vegetarianism may be associated with lower cholesterol (胆固醇), reduced risk of overweight and heart disease.

“We know from other studies that brighter children tend to behave in a healthier fashion as adults—they’re less likely to smoke, less likely to be overweight，less likely to have high blood pressure and more likely to take exercise.” lead author Catharine Gale said, “This study provides further evidence that people with a high IQ tend to have a healthier lifestyle.”

In the study, Gale’s team collected data on nearly 8,200 men and women aged 30, whose IQ had been tested when they were 10 years of age.

“Children who scored higher on IQ tests at age 10 were more likely than those who got lower scores to report that they were vegetarian at the age of 30.”Gale said.

The researchers found that 4.5 percent of participants were vegetarians. Of these, 2.5 percent were vegan, and 33.6 percent said they were vegetarian but also ate fish or chicken.

There was no difference in IQ score between strict vegetarians and those who said they were vegetarian but also ate fish or chicken，the researchers added.

One expert said the findings weren’t the whole answer，however.

“We don’t know the beliefs or attitudes of the parents of the children，nor do we know if there was a particular event that led these children to becoming vegetarian in their teens or adulthood.” said Lona Sandon, and assistant professor at the University of Texas Southwestern Medical Center at Dallas.

1.From the article，we know that ________.

A．brighter children are likely to become vegetarians when they are ten.

B．people with a higher IQ will not be overweight

C．brighter children are likely to have a healthier lifestyle

D．overweight may cause high blood pressure

2.What does the underlined word “vegan” in the sixth paragraph mean?

A．Someone who only eats vegetables.

B．Someone who chooses not to eat meat or fish.

C．Someone who likes eating meat and fish.

D．Someone who likes eating vegetables.

3.This study left some unanswered questions EXCEPT “________”．

A．Did the vegetarian children grow up in a family with a vegetarian parent?

B．Did the children eat a primarily vegetarian diet at the age of 10?

C．Were meatless meals regularly served in the participants’ families?

D．Did the vegetarian children really have a high IQ?

4.The main idea of the passage is that ________.

A．the low IQ children will be unhealthier when they grow up

B．being vegetarians can reduce the risk of overweight and heart disease

C．IQ is important to vegetarians

D．high IQ children are more likely to become vegetarian when they grow up
