233638. （2025•师大附中•四模）     Beer（啤酒）and eggs are commonly seen in the kitchen.However，scientists recently found that they were used in historic paintings，too.
    To store Danish paintings，a group of researchers studied what ancient paints were made of.They did experiments on small pieces of paintings that had already been cut off from the original（原始的）artwork.
    According to their paper published in Science Advances，grains and yeast（粮食和酵母）were found on the base of the paintings.Beer was the most common drink in the 19th century in Denmark，and its by-products were spent grains and yeast.
    The study showed that they were used to provide a stable（稳定的）painting surface.Researchers also pointed out that beer by-products（副产品）were used as a"glue"because they had a lot of sugar.With beer added，the paint could also dry faster.
    Apart from beer，the egg has long been found in oil-based paints used by artists in the 15th century，such as Italian painter Leonardo da Vinci.A recent study published in Nature Communications may have cracked the secret of how eggs can help store artworks.
    The researchers re-created the ancient paint by adding egg yolks（蛋黄）to oil paint.They then looked into how it changed over time.The findingowed that the yolk's proteins（蛋白质）helped slow the oxidation（氧化）of the paint.It could also reduce wrinkling（起皱纹）as the egg makes the paint smoother.
    However，the oil paint with added eggs usually takes longer to dry.It seemed fine for artists——they were willing to accept that to have their works stored for longer.
    "The more we understand how artists choose and use their materials，the more we can appreciate（欣赏）what they're doing"，Ken Sutherland，an expert at the Art Institute of Chicago，US，told Science News.Sutherland added that research like this could help people have a deeper understanding of the artworks.
76. According to the recent findings，where were beer and eggs used？
They were used in        .
77. What were found on the base of the paintings according to Paragraph 3？
       were found on the base of the paintings.
78. Which English word in the passage is the closest in meaning to"crack"？
It is"        ".
79. How could the paint feel after the yolk's proteins worked（起作用）？
The paint could feel        .
80. According to Ken Sutherland，how could the research like this help？
It could provide        of the artworks.

127691. （2024•高陵区•八上期末） $德优题库$ Chinese scientists create robots for picking tea Do you often see robots around you？What do they help with？Look，here are tea-picking robots!
    In a Hangzhou tea garden，a smart tea-picking robot created by Zhejiang Sci-Tech University worked for the first time. "We took thousands of pictures of new tea buds（芽） and fed them to the robot for it to learn.The robot uses an AI model to recognize（识别） the buds it needs to pick，" said Professor Chen Jianneng.This lets the robot find the right tea buds about 90 percent of the time.
    The robot's arm pulls and then sucks（吸） up the tea buds.These buds are quickly moved into a special box.After the robot puts all the buds together，it moves the buds from the box to a main box.
    They made the robot because there are not enough people to pick tea.About 400，000 more workers are needed. "Tea-picking robots are a trend （趋势） of the future.About five years from now，the robots will do the job of picking West Lake Longjing tea in place of people，" said Professor Wu Chuanyu，who leads the research team.
Room for improving ●Telling the difference better
    Some tea buds look similar and they are very close to each other.These things make it hard for the robot to pick the right ones and pick them well.

234126. （2025•新城区•二模） SEA SWEEPER 1000 Nowadays，the amount of sea rubbish is increasing.And the sea environment is seriously polluted.Traditional methods of cleaning sea rubbish have high costs，and may hurt fish.These problems can be successfully solved by a sea rubbish cleaning robot.It is called Sea Sweeper 1000 and looks like a lantern fish from the outside.
    The robot has two "stomachs"，which are used to store，recycle and burn rubbish.The left stomach will be used to burn down rubbish and create energy for the robot to keep running.And the things left after burning will be divided into small parts，and then placed into the bags on the robot's back rather than thrown into the sea.And the right stomach can store rubbish that can be recycled.When it gets full，rubbish will be placed in the bag on the robot's tail.Once the bag is full，the robot will come back.
    The lantern above its head has a sensor （传感器） and a camera.The sensor is used to avoid taking in fish.But if the robot fish does take in small fish，don't worry，because the space between its teeth is big enough for them to swim out.And the ★ is used to take photos.These photos will be sent to its user when there is rubbish，which allows the user to make sure if the rubbish needs to be recycled or burned.
    Although there are still some parts that need to be improved，with the robot's assistance，we can protect the sea environment and create a better future for human beings.

（1）What does Sea Sweeper 1000 look like？
It looks like         from the outside.
（2）Look at the picture on the right.In which part will the rubbish be placed when the right stomach gets full？

234327. （2025•未央区•二模）     On January 20，2025，a Chinese tech company named DeepSeek made a new AI called DeepSeek-R1.This smart program can solve math problems，write code，and answer questions like top models such as OpenAI's GPT-4 o，but it costs much less to build.The team spent only＄5.58 million（1/70 of OpenAI's cost）and used2，048 computer chips（芯片）for two months.Thiows that good ideas can beat big money.
    DeepSeek-R1 learns by trying many times and getting better，like how students practice maths.Other AIsneed lots of prepared examples，but R1 improves by itself.For example，in a global math test，it got79.8% right，a little higher than OpenAI's model.A simple version（版本）of R1 can even run on low-cost（低成本的）computers，helping schools and small companies.
    DeepSeek-R1 is free to use and change.On its first day online，over 19，000 programmers worldwide started projects to study it.A German scientist said experiments with R1 cost＄10 instead of＄300 with other AIs.Even Meta（a famous U.S.tech company）top scientist said，"This kind of free AI could change the world."
    U.S.tech companies are worried.Meta plans to spend＄65 billion more on AI research.Experts say China is catching up fast.A report in Nature magazine called R1 a "big step forward"，proving that smart ideas beat （打败） expensive tools.
    As a DeepSeek engineer said， "We want AI to be a friend，not something only rich people can use." With R1，China shows the world that great things come from new ideas and hard work，not just money.

234355. （2025•铁一中学•三模） $德优题库$ Facial-recognition cameras（面部识别摄像头） are everywhere even in your smartphone.Many people use this technology to unlock their phones，open doors or make quick payments.But there is a problem：someone wears masks.What a headache!
    Scientists are trying to solve this problem.For example，Engineering and Technology（E&T） magazine reports that Hanwang，a tech company in Beijing，has made a new system.It can recognize 95% of people when they wear masks.
    What's the secret？It's all about your eyes.Marios Savvides from Carnegie Mellon University studies facial-recognition.As we get older，he says，our faces change shape.But the area around our eyes doesn't.It stays the same even if we put on weight.As long as there are enough data from the area of our eyes，the cameras can recognize us.
    Tech5 is another facial-recognition company.The Swiss company's products scan the shape of your face.They also scan your iris（虹膜），which is the colored part of your eyes.Tech5 hopes to ignore all of the face below the nose.This kind of software is more important than just unlocking your phone. "It can discover criminals，even when they wear masks."said Wang Li from Hanwang.Hanwang's technology is used by Chinese police in places like subway stations and airports.Similar technology is used by the United States Air Force.
    Wang pointed out one big weakness：it fails when people wear both a mask and sunglasses.In this situation，all of the key facial information is lost.
