Could you tell the class in English what you know about a green house?A green house is built of glass to be used for growing plants. The air inside the green house is warm because the glass lets in the sun and keeps it from running away. So the air inside is warm and is good for growing plants throughout the cold seasons.2.

Book 6Unit 4Global warmingⅠ.阅读理解(2018·河北保定二模)Given the recent interest in green buildings in the media，let’s think differently.Instead of focusing on increasing the supply of energy，what if we focus on reducing demand?Can we start with ending the open-door practice of street-front shops? While cool air from these shops is refreshing to pedestrians，it carries a cost.Energy is used in the air conditioning process.So it must be possible to look for changes in regulations that would encourage more energy-saving designs.For instance，if we fix ceiling fans，air-conditioning homes could surely be avoided for part of the year.Ceiling fans use far less energy.They were common in buildings before air conditioners were available.I wonder how many hours in a year air conditioners could stay if ceiling fans were fixed.In homes built under the small-house policy in New Territories，the ceiling may be too low for ceiling fans.If the 9-meter maximum building height regulation were relaxed，ceiling fans could be fixed to reduce energy use.Current thinking in sustainable building design and operation involves integrated(协调统一的) design；that is，bring together all parties to create a building with better performance that achieves energy reduction.For integrated design to succeed，all parties must come together and think beyond each person’s circle of influence.Better solutions are impossible to avoid with integrated design.Buildings would no longer be engineered after the basic architecture was built.Positive project outcomes may include reduced air-conditioning load，reduced power use for electric lighting，and a reduction in the amount of materials used.We need to ask if we are ready to look beyond our own small circles and seek an improved approach to building design.By that I mean an integrated design resulting in more sustainable buildings.1.What’s the author’s attitude towards the open-door practice of the street shops?A.Supportive.B.Disapproving.C.Optimistic.D.Uncaring.答案B解析观点态度题。

The little panda went without a name for his first hundred days in observance of a Chinese custom. It’s rare for pandas, born in captivity, to live more than a few days, and keeping the animals nameless is seen as a way to trick fate into letting them survive.The cub wasn’t present at his naming ceremony. The zoo officials said he probably wouldn’t be making his public debut until some time in December. Panda fans celebrated Tai Shan’s day at a zoo ceremony featuring performances by Chinese dance troops and martial artists.Tai Shan usually spends the morning with his mother, Mei Xiang. His handlers are slowly introducing him to the exhibit where he’s expected to go on pub lic view within the next couple of months. Mei Xiang and the father, Tian Tian, are on a 10-year loan from China. The cub will be sent to China. when h e is 2 years old.The China Wildlife Conservation Association and the zoo official had selected five names from which voters could choose.
