1、2020年精编人教版英语资料Unit 5 The power of nature.阅读理解AWe all know the feeling of walking into an air-conditioned office building on a hot summer day. Its 94 outside. Its 64 inside. Suddenly, you need a knit sweater just to sit at your desk. I know someone who used to bring a space heater to workin August.As
2、ide from being uncomfortable, this is horrifically inefficient. The low hum of the air conditioner is the sound of coal being burned and money being spent to make you miserable at work. BuildingIQ is trying to change that. Their secret weapon? Machine learning.The company has developed cloud-based s
3、oftware that gathers information about a building and uses it to build a thermal model (热模型). That model can predict how much or how little energy is needed to keep the people inside comfortable by analyzing factors like indoor temperature and pressure, electricity consumption, the weather forecast,
4、 the price of electricity, and therefore tailors heating and air conditioning for maximum energy efficiency.Thanks to a recent cooperation, BuildingIQ will soon take human preferences into account. Changes to heating and air conditioning are always influenced by the limits of human comfort, and thos
5、e limits vary from person to person. This data will be added into the thermal model. Imagine a retirement home where the occupants are always too cold. If the system knows this, it will reduce the air conditioning in the summer to keep grandma and grandpa nice and warm.How well does it work? Buildin
6、gIQ says it regularly saves between 10 and 25 percent on heating and air conditioning, the two items that make up 50 or 60 percent of a buildings total energy use. The software will help cut energy bills and improve comfort all while reducing our reliance on fossil fuels. It wont be long before you
7、can leave your space heater at home.1. In Paragraph 1, the author intends to .A. complain about the coldness in air-conditioned officesB. describe the harmful effects of an unhealthy lifestyleC. criticize some peoples unawareness to save energyD. indicate the low efficiency of the old way of air con
8、ditioning2. According to the article, what does the “thermal model” do?A. Gathering information about a buildings history.B. Learning about machines that heat a building.C. Predicting the amount of air conditioning needed.D. Analyzing the physical fitness of people inside.3. The underlined word “tai
9、lor” can be best replaced by .A. limitB. adjustC. expandD. prevent4. What is the main idea of Paragraph 4?A. BuildingIQ is going to be experimented at retirement homes.B. BuildingIQ will also analyze human temperature preferences.C. People have different preferences for temperature and comfort.D. Th
10、e limits of human comfort vary and change at different ages.BRainforests, it turns out, are not created equal. Take the Amazon rainforest, an area that covers about 7 million square kilometers. But within that huge expanse are all kinds of ecological zones, and some of these zones, says Greg Asner,
11、are a lot more crowded than others.“Some forests have many species of trees,” he said, “others have few. Many forests are unique from others in terms of their overall species composition” And all of these different small areas of forest exist within the giant space that is the Amazon Rainforest.So A
12、sner, using the signature technique called airborne laser-guided imaging spectroscopy, began to map these different zones from the air. “By mapping the traits of tropical forests from above,” he explains, “we are, for the first time, able to understand how forest composition varies geographically.”T
13、he results show up in multicolored maps, with each color representing different kinds of species, different kinds of trees, the different kinds of chemical they are producing and using, and even the amount of biodiversity, the animal and plant species that live within each zone.Armed with this infor
14、mation, Asner says decision-makers now have “a first-time way to decide whether any given forest geography is protected well enough or not. If not, then new protections can be put in place to save a given forest from destruction.”Asner says the information is a great way for decision-makers to devel
15、op a “cost-benefit ratio type analysis.” Conservation efforts can be expensive, so armed with this information, government leaders can ensure they are making the most of their conservation dollars by focusing on areas that are the most biologically diverse or unique.The next step, Asner says, is to
16、take his project global, and to put his eyes even higher in the sky, on orbital satellites. “The technique we developed and applied to map Peru is ready to go global.” Asner said. “We want to put the required instrumentation on an Earth-orbiting satellite, to map the planet every month, which will give the best possible view of how the worlds biodiversity is ch
