At a conference on self-driving cars，Mike Harp，a government official，asked a seemingly simple question about what happens when his own car meets a driverless vehicle."If I honk（按喇叭），will it do any good？"Harp wanted to know.Unfortunately，manufacturers didn't have an answer."We haven't reached that point of deciding how and whether it would be appropriate for vehicles to react and in which way to honking，"said one of jye.aim.The brief exchange highlights a thorn in the side of automakers and policymakers alike：Self-driving cars will have to share the road with human drivers，likely for decades to come.Those vehicles must therefore respond and adapt to the peculiarities and mistakes of humans behind the wheel.
Self-driving technology has already come a long way.Cars being tested on the road today use cameras and radar，for example，to detect the movements of nearby cyclists and pedestrians.There are already driver-assist technologies built into some cars that monitor the speed of vehicles around you，detect potential accidents before they occur，and automatically slow or stop the car to avoid a wreck.In a world where all cars drive themselves，the technology could operate at peak efficiency.Supporters of self-driving cars say that speed limits could be raised and fatal crashes largely avoided as no traffic laws are broken and poor drivers become a thing of the past.
But the change to driverless vehicles is expected to be gradual，and will likely start with ride-sharing services，as the costs of personally owning a self-driving car remain extremely high.That means man and machine will have to play nice on roadways."There are so many interesting situations，"such as honking a horn，Harp said.When"another car with a driver meets a self-driving car without a driver in there and they realize that，it will frighten some people.How that's going to be dealt with will be part of the fun part of this process."
Any driver can tell you that driving involves a lot of social interaction，particularly the hand gestures and eye contact of fellow drivers.Much of that interaction between drivers will eventually be digital as cars increasingly collect data and share it with the vehicles around them.If a car speeds up，slows down or prepares for a stop，for example，that would be communicated immediately and electronically to the other vehicles on the road.Like self-driving technology，however，it will be years before the vehicle-to-vehicle communication is common.
That challenge is being taken into account as driverless vehicles are tested on public roads.But the honking issue is particularly tricky because it's subject to interpretation.It's going to be really hard for a driverless vehicle，even if it hears the honk，to figure out what that honk means.

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．
（5）Of all the six to 17-year-olds in the Scholastic study，more than 90%said their favorite books are the ones they chose for themselves．
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．發布：2025/1/1 13:30:1組卷：18引用：9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.
（1）What's the main idea of the second paragraph？
A．Chinese students ask for sick leave most often.
B．Chinese students drink most alcohol and smoke earliest.
C．Japanese students ask for least sick leave.
D．Chinese teenagers are tallest，but most unhealthy.
（2）It can be inferred from the passage that.
A．Chinese students are confident in themselves and luckier
B．Chinese students are luckiest，yet most unsuccessful
C．Japanese students are most stressed
D．South Korean students sleep the least
（3）What does the underlined word "that" refer to？

C．the weight
D．the appearance
（4）The worries that causes students to be stressed come from the following factors EXCEPT.
A．study and career
B．friendships
C．physical appearance
D．family relationship發布：2025/1/1 16:0:1組卷：0引用：3難度：0.5 -
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.發布：2025/1/1 16:0:1組卷：25引用：4難度：0.5
