7.We all know the feeling of walking into an air-conditioned office building on a hot summer day.It's 94℉outside.It's 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 work-in August.Aside 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 software 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,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 those 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?BuildingIQ says it regularly saves between 10and 25percent on heating and air conditioning,the two items that make up 50 or 60 percent of a building's total energy use.The software will help cut energy bills and improve comfort all while reducing our reliance on fossil fuels.It won't be long before you can leave your space heater at home.
27.In Paragraph 1,the author intends to.D
A.complain about the coldness in air-conditioned offices
B.describe the harmful effects of an unhealthy lifestyle
C.criticize some people's unawareness to save energy
D.indicate the low efficiency of the old way of air conditioning
28.According to the article,what does the"thermal model"do?C
A.Gathering information about a building's 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.
29.The underlined word"tailor"can be best replaced by.B
A.limit
B.adjust
C.expand
D.prevent
30.What is the main idea of Paragraph 4?B
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.The limits of human comfort vary and change at different ages.
分析 本文主要介绍了BuildingIQ的工作原理和优点,BuildingIQ通过热模型调整供暖和能源效率而且能分析人体对温度的喜好.

Chinese writing began thousands of years ago.According to an ancient story,a man named Cang Jie invented Chinese writing.One winter day while he was hunting,he saw the tracks of animals in the snow and observed that the appearance of each one was different.Then he had the idea that he could use different shapes to represent different objects.The first Chinese characters were drawings of physical objects.Some characters have been simplified and others have been made more difficult over time.However,as a whole the characters have developed from drawings into standard forms.
Not all characters were developed from drawings of objects.Sometimes to express ideas,some characters were made by combining two or more characters together.Other characters were developed for directions and numbers.It is easy to distinguish their meanings by looking at them.
Though these kinds of characters indicate meanings,one of their shortcomings is that they do not show how they should be pronounced.Therefore,a method was developed to have one part of a character indicate the meaning and the other suggest the pronunciation.Many Chinese characters used today were made this way.
In the 1950s the Chinese government introduced simplified Chinese characters and now they have widespread use in China's mainland.
Brief(61 )intruduction | The Chinese language is (62 )different from western language because it uses characters to (63 )represent ideas,objects or deeds. |
The origins of Chinese characters | An idea (64 )occurredto Cangjie after he observed the tracks of animals (65 )whose appearance differed from each other in the snow. |
