Our world is steeped in history.In nearly every city on every continent，there are sites to be seen that remind us that our generation was not the first.They show us that those who came before had rich cultures，and they inspire us to engage in （參與） their stories.But these essential sites are under threat from natural disasters，warring peoples and even tourists.
Fortunately，concerned citizens are trying their best to preserve ancient sites.Respected organizations like UNESCO are stepping in to guard world heritage locations，and a large number of charities have sprung into action to give new energy to damaged or destroyed structures.But with modern technology comes the opportunity to go one step further：to capture（拍攝）sites digitally.This is the goal of the US-based company CyArk，whose founders were moved to act after hearing of the senseless destruction of ancient ruins.
Using a combination of Light Detection and Ranging（LiDAR）technology and photogrammetry （攝影測(cè)繪），CyArk captures details of ancient sites in their entirety，creating a photorealistic 3 D model.LiDAR is the most important technique used for capturing 3 D blueprints of a structure.It relies on pulses of light being shot at and bounced back from the structure's surface to capture both depth and details.LiDAR units can be handheld，or mounted on an aircraft to document inaccessible and large spaces with great precision.Photogrammetry is a free-of-charge technique that involves the use of digital imagery to gain measurement information and appearance details.These are later combined with the LiDAR data to create a faithful，digital reconstruction of an ancient site.
Besides repairing damaged sites with the help of LiDAR，CyArk has made a great effort to engage people directly with virtual space.With VR （virtual reality） devices，we can now experience ancient wonders anywhere.

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．

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：21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.
