Buildings can become greener. They can use more recycled steel and can be built in off-site factories,greatly reducing lorry journeys. But no other building material has environmental credentials(认证)as exciting and overlooked as wood.
The energy required to produce a laminated(复合的)wooden beam is one-sixth of that required for a steel one of comparable strength. As trees take carbon out of the atmosphere when growing,wooden buildings contribute to negative emissions by storing the stuff. When a mature tree is cut down,a new one can be planted to replace it,capturing more carbon. After buildings are pulled down,old beams and panels are easy to recycle into new structures. And for improving older buildings to be more energy efficient,wood is a good insulator(绝缘体),A softwood window frame provides nearly 400 times as much insulation as a plain steel one of the same thickness and over a thousand times as much as an aluminium one.
A race is on to build the world's tallest fully wooden skyscraper. But such buildings are still uncommon. Industry disunity,cut-throat competition for contracts and low profit margins(差额)mean that most building firms have little money for greener construction methods beyond what regulation requires
Governments can help urge the industry to use more wood,particularly in the public section. That would help wood-building specialists achieve greater scale and lower costs. Zero-carbon building regulations should be changed to take account of the emissions that exist in materials. This would favour wood as well as novel ways of producing other materials.
Construction codes could be adjusted to make building with wood easier. Here the direction of travel is wrong. Britain,for instance,is banning the use of wood on the outside of tall buildings after 72 people died in a tower fire in London in 2017.That is a nonsense. Grenfell Tower was covered in aluminium and plastic,not wood. Modern cross-laminated wood panels perform better in fire tests than steel ones do.
Carpentry alone will not bring the environmental cost of the world's buildings into line.

These days a green building means more than just the color of the paint. Green buildings can also refer to environmentally friendly houses, factories, and offices.
Green building means "reducing the effect of the building on the land", Taryn Holowka of the U.S. Green Building Council(评议会) in Washington, D.C., said. According to Holowka, building account for 65 percent of total U.S. electricity use.
But green building can reduce energy and water use. Also, the building are often located near public transportation such as buses and subways, so that people can drive their cars less. That could be good for the environment, because cars use lots of gas and give off pollution. Green building are often built on developed land, so that the buildings don't destroy forests.
Marty Dettling is project manager for a building that puts these ideas into action. The Solaire has been called the country's first green high-rise building. According to Dettling, "We've reduced our energy use by one-third and our water by 50 percent."
The Solaire cuts energy in past by using solar power. "On the face of the building we have solar panels(光板) which change the sun's energy into electricity," Dettling explained.
The Solaire also has lights that automatically turn off when people leave the room. In addition, the building has lots of windows, allowing people to use the sun for light during the day. The Solaire cuts water by reusing it.
Not everyone is eager to move into a green building, however. Some people think that things like solar panels cost more money than more traditional energy sources. Anyhow, Holowka said, "It's going to be big."
1.A green building means .
A. a building that uses no electricity B. a building occupying
C. a building that saves energy and water D. a green-colored building
2.A green building is often built on an area of land .
A. which has already been for buildings
B. which has thick forests around
C. where people of high income live
D. where traveling around by car is most convenient
3.When Holowka says in the last paragraph, "It's going to be big", she means that green buildings .
A. will be more comfortable
B. will become popular in future
C. will be more environmentally friend
D. will take the place of traditional building
4.Which is the main idea of the passage?
A. Dettling designed the first green building in the U.S.
B. The Solaire serves as a model of high building
C. Green buildings help save environment
D. Energy shortage calls for buildings of new design

People tend to become more personal and hide less of themselves when using email . Researchers from Open University in Britain have found in a recent study that there are good reasons for this .
The team of researchers asked 83 pairs of students , all strangers to each other , to solve a problem . They had to discuss this question : If only five people in the world could be saved from a world disaster , who should they be ? The pairs of students had to talk over the problem either face to face or by computers . Dr. Johnson said , “They told their partners four times as much about themselves when they talked over the Internet as when they talked face to face . When the computers were fitted with cameras so that students could see each other , this limited the personal side of the conversation.”
Generally the information was not extremely personal . It was mainly about things such as where they went to school, or where they used to live . But some students discussed their love stories , and personal childhood experiences .
Dr. Johnson believes that emailing encourages people to focus on themselves . And when they do this , they become more open , especially if there are no cameras. “If you cannot see the other person, it becomes easier to talk about yourself . This is because you are not thinking what the other person is thinking of you. So emailing has become the modern way of talking,” said Dr. Johnson. However , this style of talking is not entirely new . “In the 19th century people started to use the ‘telegraph’ to communicate . Now the same kind of thing has happened and people ended up speaking more freely .”
Dr. Johnson thinks that emailers need to know about these effects of emailing , especially when they start work in a company . “If you don’t know about it , you could find yourself saying more about yourself than you wanted to .”
1.The subject discussed in this passage is ________ .
A.how people open up when emailing | B.how people do research studies |
C.how to communicate at work | D.how to discuss and solve a problem |
2.The reason that some couples talked freely about themselves is that ________ .
A.they didn’t talk about very personal things | B.they couldn’t see each other |
C.the cameras on the computers were turned on | D.they had to discuss a question |
3.What do the underlined words (in para. 4) refer to ?
A.The telegraph | B.The computer | C.Emailing . | D.Face-to-face talk . |
4..In the writer’s opinion , one should ________ .
A.focus on oneself when emailing | B.talk more freely in email than usual |
C.discuss any subject that one wants to | D.consider how one uses email at work |
________
