Usually, we think that older peoples memory becomes bad because their brains get weak. But now a team of scientists at the University of Tubingen in Germany has a new idea.The human brain works slower in old age， says Michael Ramscar, the lead scientist. But only because they have stored more information overtime. The findings are based on a series of computer simulations(模拟)of learning and memory. Scientists let the computers read a certain amount of words and learn new things each day. When the computer reads only so much, its performance on cognitive(认知)tests is similar of a young adult. But if the computer learns the experiences we might encounter over a lifetime, its performance is similar to that of an older adult.Often it is slower, but not because its processing capacity has declined. Rather, increased experience has caused the computers database to grow, giving it more data(数据)to process-which takes time. This is similar to old people. Imagine a person knows two peoples birthdays. Another person knows the birthdays of 2000 people, but can only match the right person to the right birthday nine times out of 10. Can you say the first person has a better memory than the second person?26 .

Where would this passage most probably appear?AIn a magazine.BIn a story book.CIn an ad.DIn a guidebook.29 . What would be the best title for the passage?ADo old people have a bad memory?BScientists new findings on brainsCHuman brains processing capacityDWhich is better, the old or the young?Dont be surprised if you see a car going down the road without a driver in Beijing these days.In March, 2018, baidu was given a license to test its self-driving cars in Beijing, China Daily reported.Self-driving cars have been in development since 2010, when google announced that it was making such cars. Since then, companies like Tesla, Uber and Baidu have been working to produce and test their own self-driving cars. self-driving cars are expected to change the way we get around. They are safer and more environmentally friendly than regular cars. They can remove the stress(压力) of driving and allow disabled or blind people to get around mroe easily.
