試題詳情
Houses have been getting progressively "smarter" for decades,but the next generation of smart homes may offer what two Case Western Reserve University scientists are calling an "Internet of Ears".
Today's smart home features appliances,entertainment systems,security cameras and lighting,heating and cooling systems that are connected to each other and the Internet.They can be accessed and controlled remotely by computer or smartphone apps.
But a group of electrical engineering and computer science professors in the Case School of Engineering have been experimenting with a new suite of sensors (傳感器).This system would read not only the vibrations (震動),sounds and even other movements associated with people and animals in a building,but also any slight changes in the existing electrical field.
While there still maybe a decade or so away,the home of the future could be a building that adjusts to your activity with only a few small,hidden sensors in the walls and floor without the need for monitoring cameras.
"We are trying to make a building that is able to 'listen' to the humans inside," said Ming Chun Huang,an assistant professor in electrical engineering and computer science."We are using principles similar to those of the human ear,where vibrations are picked up and our algorithms (計(jì)算程序) recognise them to determine your specific movements.That's why we call it the 'Internet of Ears'."
"There is actually a constant 60 Hz electrical field all around us,and because people are somewhat conductive,they short out the field just a little," Huang said."So,by measuring the disturbance in that field,we are able to determine their presence,or even their breathing,even when there are no vibrations associated with sound."
Huang said they have used as few as four small sensors in the walls and floor of a room.
As for privacy concerns,the system would not be able to identify individuals,although it could recognise people's different ways of walking.
(1)What uniqueness does the smart home of the next generation have? DD
A.It uses the advanced Internet technology.
B.It is controlled remotely by a computer.
C.It features appliances and entertainment systems.
D.It can read vibrations,sounds and movements.
(2)What's the key part of the system in the smart home? AA
A.The sensors.
B.The vibrations.
C.The electrical field.
D.The monitoring cameras.
(3)Which is the function of the smart home of the next generation? AA
A.Determining people's presence.
B.Recognising different people.
C.Protecting individuals' privacy.
D.Measuring the electrical field.
(4)What may be the best title for the text? DD
A.Various Smart Houses.
B.Benefits of Smart Houses.
C.How Do Smart Houses Work?
D.What Are Next Smart Homes Like?

1.For some people,the warmest memories from childhood come from being read a great story.(1)
A new report by the American Academy of Pediatrics says reading aloud is so important that parents should start as soon as their children are born and continue to read aloud even after their children can read by themselves.They say parents should also point to and talk about pictures in books for infants(嬰幼兒).(2)
The company Scholastic is fl major U.S.publisher of children's books.Every two years,Scholastic publishes a report on American reading attitudes and habits.The 2015 report says only 31 percent of children in the U.S.read a book for fun almost every day.

(5)
A.The Scholastic report also suggests permitting children to choose their own books.
B.Scholastic also identifies some ways to develop a love of reading in a child.
C.A book does not have to be serious to be good for kids.
D.For young children,parents should ask questions about the book.
E.Do children still read for fun?
F.Another way to develop a reading habit in children is to read to them.
G.But reading to children does more than create warm memories.發(fā)布:2025/1/1 13:30:1組卷:15引用:8難度:0.7 -
2.Chinese students always complain that they're under great pressure and don't get enough sleep.But they may be surprised to learn that they're much luckier than their peers(同齡人)in South Korea and Japan,according to a recently published report,conducted by Shanghai Academy of Social Sciences on the physical and mental health of senior high school students in the three Asian countries.
According to the study among nearly 6,000 high school students in the three countries,Chinese students are the tallest but poorest in physical fitness.Chinese students are on average 168.17cm,compared with 167.61cm for South Korean students and 164.70cm for Japanese students.Chinese students asked for sick leave more than students in other countries.About 72 percent of Korean students never asked for sick and injury leave during high school,compared to 53 percent for Japanese students and 45 percent for Chinese students.Moreover,Chinese students drink alcohol and smoke earlier than Korean and Japanese students.Around 70 percent of Chinese students have drunk alcohol,compared to 50 percent for Korean and Japanese students.
According to the survey,Japanese and South Korean students suffer more pressure than their Chinese peers.Statistics show 16 percent of students in China said they experienced mental pressure often over the past year,while the numbers in Japan and South Korea were 33 percent and 47 percent respectively.Their worries come from "study","future after graduation", "friendships" and "relationship with their parents".To go with stress,57.9 percent of Korean students sleep the least,less than six hours a day,compared with 46.6 percent of Japanese students and 30 percent of Chinese students.
More Chinese students were satisfied with their physical appearance,double that of students in the survey from Japan and South Korea.The report said that over half of students in South Korea had tried to lose weight in the past year,while in China the figure was only 22 percent.In measures of self-worth,such as "I think I am valuable" and "I think I am successful","I can complete many things", "I won't give up to failure," Chinese students showed greater self-confidence than students in Japan and South Korea.

A.Chinese students ask for sick leave most often.

3.Paying ﹩25,000 to get your pet cloned might sound attractive,if you have the money and can't imagine life without your pet.
There are two companies now that can clone your pet:ViaGen and Sooam Biotech.Lab techs there will clone your pet using a process called somatic cell nuclear transfer (體細(xì)胞核移植),the same method used to clone Dolly the sheep in 1996.This involves removing the nucleus from a female's developing egg cell and replacing it with the nucleus from a cell from the animal you want to clone.The new cell is then stimulated (刺激) with an electric shock to make it divide and then implanted into a host organism (有機(jī)體).
The decision to clone your pet has to take place while they're still alive.You need to sign up with the company and take your pet to the vet so they can harvest some cells.Then,for between ﹩1-2000,the company will store the cells.Even if you decide to stop,there's no refund for the storage.If you decide to have your pet cloned,you'll pay a much larger deposit to perform the cell transfer and implant the cells into a host animal.
What's most important to consumers is the product.Your clone is a twin of your former pet,but it won't necessarily look or act like the original.They may have different colors and you don't get your money back.Even the companies admitted in New York Times "You can clone the look of a dog,but you can't clone the soul."
(1)Why did the author mention Dolly the sheep?
A.To ensure the safety of cloning.
B.To show that it is easy to clone sheep.
C.To prove the technology has a long history.
D.To tell readers the method used to clone their pets.
(2)What can we know about cloning a pet?
A.Your pet can be brought back to life.
B.The charge of pet cloning is ﹩1-2000.
C.Your new pet will have a parent when cloned.
D.The company will refund you if you give up halfway.
(3)What do the companies' words in the last paragraph mean?
A.Cloning is a moral issue.
B.The future of cloning is unclear.
C.The technology of cloning is not perfect.
D.Yon won't get the exact copy of the former one.
(4)Where is the text most likely from?
A.A travel guide.
B.A newspaper.
C.A science fiction.
D.A textbook.發(fā)布:2025/1/1 16:0:1組卷:23引用:4難度:0.5
