It is not unusual to stare at a long restaurant menu and not be able to decide what one wants to ejye.ai.At other times it is difficult to pick an item of clothing in a shop with plenty of items from which to choose.
According to a new study published in Nature Human Behavior in October，this is the phenomenon of "choice overload （選擇超荷）".It's the result of a struggle （掙扎） in our brain，Science Daily reported.
In the study，volunteers were given varying sets of six，12，or 24 landscape pictures.They were asked to choose one to be printed on a coffee mug.While they chose，a machine recorded their brain activities.
According to the research，two parts of the brain - the anterior cingulate cortex （ACC）（前扣帶皮層）and the striatum （紋狀體） - were highly active in the process.The ACC is responsible for the potential costs of decisions while the striatum is to determine （決定） value，Neuroscience journal noted.The study suggests that our brain needs to weigh both reward and workload to make a proper decision.
After further study，the researchers reported that these two parts are likely to be more active for the 12-item set than the other two sets.That's because 12 is a good number，not "too small" or "too large" in the choice pool.
"As the number of options increases，the potential reward increases，but then begins to level off due to increasing amount of workload，" Colin Camerer，a professor of California Institute of Technology，US，told Science Daily.
But that doesn't mean 12 is the magic number for decision making.According to Neuroscience journal，the proper number of options for a person is probably "somewhere between 8 and 15".Still，many people prefer to have a large number of options to choose from even if the experience can be distressing，researchers reported.
According to the UK journal Medical News Today，it's partly because people tend to feel freer and more able to control their lives when there are more options.
"Essentially，our eyes are bigger than our stomachs，" Camerer told Sci-news. "When we think about how many choices we want，we may not be mentally representing the frustrations of making the decision."

A．How to make wise decisions quickly.
B．How people feel after making choices.
C．How the number of choices influences one's decision.
D．How the brain makes choices.
（2）Why did the participants prefer the 12-item set in the study？ CC

1．Technology is forever changing the way we get our news.Most people now get a lot of their news on electronic devices，instead of traditional media，such as newspapers，television or radio.An increasing number of people also report turning to social media for information.
Now，there is a new technology that could greatly change the way we get the news：computer-created news readers.China has launched what it called the world's first artificial intelligence，or AI news presenters.
The news readers，supported by machine learning technology，are based on two real-life Chinese newsmen.One is able to present news broadcast in English；the other，in Mandarin Chinese.A report said machine learning was used to examine video images and sounds of the two newsmen.Similar technology has been used to create video products known as "deepfake videos".A deepfake video is a video that looks real，but was electronically changed.Such videos can make people appear to say things they never said.
It's said that the AI presenters will be a great improvement to the news team because they "can work 24 hours a day" on its website and on social media.One of the presenters even promised to "work tirelessly" to keep people informed.Some machine learning experts said the system showed off China's latest progress in voice recognition，text-to-speech technology and data analysis.
Others wondered about the effects robots might have on employment and workers.Some people argued that only low-level jobs requiring heavy labour will be easily replaced by robots.Others praised the technology as a way for companies to make money from low-cost labour machines.
Anyway，for its great potential，some businesses have experimented with similar technology for possible use in news operations.
（1）People now get information mainly from.
A．electronic devices
B．traditional media
C．social media
D．AI news presenters
（2）The author mentioned "deepfake" in Paragraph 3 because.
A．it was also artificial
B．it was also developed by China
C．it also used machine learning technology
D．it also gained popularity and recognition
（3）What can we know about AI news presenters？
A．AI news presenters can only "speak" one language.
B．Not all the people are in favour of AI news presenters.
C．AI news presenters will soon replace human news readers.
D．AI news presenters can reflect the improvement in robot making.
（4）What will probably be discussed in the following paragraph？
A．Further research on the technology.
B．Other advantages of the technology.
C．Principles the technology is based on.
D．Examples the technology is applied to.發(fā)布：2024/12/18 13:30:2組卷：46引用：2難度：0.5 -
2．The TV series，The Longest Day in Chang 'an，which was shown on Chinese online platforms last summer became a hit soon.Since then，it has been shown on partnering streaming platforms and TV networks abroad.Some websites overseas also offered the program to their users paying for it—the first time a Chinese series was broadcast as paid content abroad.
"I was amazed by the overseas audience's love for this show，" Cao Dun，director of The Longest Day in Chang'an，told Beijing Review. "I was worried that they wouldn't understand the complex political structure of the Tang Dynasty.But in reality，the show is prompting foreign audiences to research Tang Dynasty's history to better understand the plot."
The unique culture in ancient China is not a barrier but a bridge to connect with foreign audiences.In the TV series，every figure is given enough space to flesh out his or her character.Telling stories of ordinary Chinese people that resonate（引起共鳴）with the audience might be the way to communicate with the world. "The success of the TV series shows that beauty is a universal language crossing borders，" he told Beijing Review.
His ambition is to distinguish Chinese dramas from the TV shows in the rest of the world. "The TV series is a step in my plan to tell Chinese stories to the world，" Cao said. "After describing the impressive beauty of the Tang Dynasty，I am looking for several plays that tell stories of today's China.I don't want to copy any country's production.Chinese dramas have to be built on our rich culture and Chinese people's everyday life，" Cao added.
（1）What do we know about the TV series？
A．It was first put on overseas.
B．It can be appreciated for free.
C．It was very popular once it was shown.
D．It is about the development of the Tang Dynasty.
（2）What does the underlined word "prompting" in Paragraph 2 probably mean？
A．Requiring.
B．Reminding.
C．Informing.
D．Encouraging.
（3）What made the TV series a success？
A．Recognition of beauty.
B．Stories of ordinary people.
C．Diversity of Chinese culture.
D．Personalities of every figure.
（4）What is Cao Dun's ambition？

3．The third-generation hybrid rice（雜交水稻）which was developed by Yuan Longping，the "father of hybrid rice"，and his team ran its first public yield（產(chǎn)量）monitoring from Monday to Tuesday and achieved high output.The final yield of the tested variety，G3-1 S/P19，came to1046.3 kg per mu（about 667 square meters），based on two pieces of land in Qingzhu Village under the city of Hengyang in central China's Hunan Province.
"Some previous high-yielding hybrid rice varieties in China took 160 to even 180 days from sowing（播種）to harvesting，while the figure was shortened to around 125 days for the new variety.This is one of the most important features（特征）of the third-generation hybrid rice that can reduce the use of pesticides（殺蟲劑）and fertilizers（化肥） ，thus reducing cost and improving production efficiency." said Qian Qian，the deputy director of the China National Rice Research Institute.
Unlike the previous two generations that required a large amount of water and fertilizers as well as demanding growing conditions and technological support，the third-generation hybrid rice is easier to be cultivated（種植） by ordinary farmers.So the soil，altitude and climate of the test site were not "ideal conditions" carefully selected beforehand but were close to the paddies （稻田） of ordinary farmers.
Nowadays.China's average yield of rice is about 500 kg per mu.Ordinary farmers can produce 600 kg to 700 kg of rice per mu by growing some excellent second-generation hybrid rice varieties.However，under the same planting conditions and environment，the yield of the third-generation hybrid rice could reach 800 kg per mu.China now feeds around 20 percent of the world's population with less than 9 percent of the world's arable （可耕種的）land.
At present，Yuan's team has nine third-generation hybrid rice combinations under trial，which are expected to achieve commercial seed production in the following three to four years and hope to apply the technology into the research of sea rice.The third-generation hybrid rice has the comprehensive strength to promote a greener and more sustainable development of China's rice production with higher quality and yield.
（1）What feature of the new hybrid rice does Qian Qian mainly talk about？
A．It saves a lot more water.
B．It achieves a higher yield.
C．It saves much more farmland.
D．It has a shorter growing period.
（2）Why is the new hybrid rice not tested in ideal areas？
A．The ordinary farmers master planting technology.
B．The researchers want to reduce the experiment cost.
C．The growing conditions the new hybrid rice needs are simple.
D．The previous rice farming provides researchers with experience.
（3）What is the fourth paragraph mainly about？
A．The high output of the third-generation hybrid rice.
B．The future of the new hybrid rice variety.
C．The advanced technology of the research on hybrid rice.
D．The differences between the three hybrid rice varieties.
（4）Where is this text most likely from？
A．A guide book.
B．A news report.
C．An advertisement.
D．A fashion magazine.發(fā)布：2024/12/19 9:0:1組卷：9引用：1難度：0.5
