Thanks to this new hands-free suitcase，carrying around heavy luggage may soon become a thing of the past.Designed by an Israeli company NUA Robotics，this "smart" suitcase will follow you everywhere you go.
The carry-on suitcase，currently a prototype （雛形），connects to a smart phone app via Bluetooth.It has a built-in camera sensor that can "see" you and follow you around on flat surfaces like airport floors.It comes with an anti-theft alarm to prevent someone carrying it away when you're not looking and it has a backup battery that you can use to charge all your devices.
"It can follow and carry things for people around while communicating with their smart phone，and avoiding obstacles，" explained Alex Libman，founder of NUA Robotics. "We're combining sensor network，computer vision，and robotics.So if you download our app，press the follow-me button，the luggage recognizes the specific user and knows to follow and communicate."
NUA is still testing the device and trying to improve features like speed and customization（定制），but they hope to make the suitcase available to customers in a year's time.If it proves successful，they want to use the Bluetooth pairing technology to automate lots of other devices，like shopping carts at the supermarket.These devices are especially meant to be useful to the physically disabled and elderly. "Any object can be smart and robotic，" Libman said， "We want to bring robots into everyday life."
The Israeli tech company made it clear that the finished product will look just like a regular suitcase.They're planning to partner with a carry-on luggage maker，since the device that makes it "smart" weighs just 2.5 pounds and can be fitted on old-fashion luggage.
With NUA's smart suitcase，carrying round heavy luggage isn't a burden.But how their invention will handle tough obstacles like stairs？It will be interesting to wait.

1．For some people，the warmest memories from childhood come from being read a great story．（1）
It develops children's language skills and increases their ability to succeed in school and，later，work．
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．
（3）One is simply to have books in the home．Elizabeth Lyttleton，the mother of three，is lucky．Her mother once wrote and illustrated children's books，so the family always have plenty to read．She says all her children learn from books-but in different ways．（4）Researchers from the Scholastic company found that 80%of children surveyed-of all ages-say they love being read to．And children ages 6 to 11 whose parents do not read to them anymore say they miss it．

2．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：19引用：4難度：0.5 -
3．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.
