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．Scientists say they have created a new device that can turn brain signals into electronic speech．The invention could one day give people who have lost the ability to speak a better way of communicating than current ones．
The device was developed by researchers from the University of California，San Francisco．Their results were recently published in a study in the journal Nature．Scientists created a "brain machine connection" that was set in the brain．The device was built to read and record brain signals that helped control the muscles to produce speech．These include the lips，tongue and jaw．
The study involved five volunteer patients who were being treated for epilepsy （癲癇）．The individuals had the ability speak and already had electrodes （電極） set in their brains．The volunteers were asked to read several hundred sentences aloud while the researchers recorded their brain activity．
The researchers used audio recordings to reproduce the vocal （發(fā)聲的） muscle movement which is the key to producing human speech．Future studies will test the technology on people who are unable to speak．
The study reports the reproduced sentences were understandable to hundreds of human listeners asked to write out what they heard．The listeners were able to write out 43 percent of sentences with perfect accuracy．
Edward Chang is a professor of the university's Well Institute．He was a lead researcher on the project．Chang admitted that much more research of the system would be needed to reach the goal of perfectly reproducing spoken language．
（1）Who will probably benefit most from this device？
A．Those unable to hear．
B．Those unable to see．
C．Those unable to speak．
D．Those unable to write．
（2）What do we know about the "brain machine connection"？
A．It could control the muscles．
B．It could produce human speech．
C．It could transform brain signals．
D．It could read and record brain signals．
（3）Which of the following is important for production of human speech？
A．Brain activity．
B．Muscle control．
C．Audio recording．
D．Vocal muscle movement．
（4）In which section of a newspaper may this text appear？
A．Science．
B．Fashion．
C．Education．
D．Entertainment．發(fā)布：2024/12/17 1:30:1組卷：9引用：4難度：0.7 -
2．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(fā)布：2025/1/1 13:30:1組卷：13引用：7難度：0.7 -
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.
（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
