9、0. “These videos brought joy and inspiration to millions of Americans in the rough year,” said Kudzi Chikumbu, director of creator community at TikTok.The platform has been widely associated with Generation Z (people born after 1996), millennials (people born in the 1980s or 1990s) and influencers w

16、the last paragraph mean?A. Makes use of. B. Goes beyond.C. Calls on. D. Takes charge of.CAs every mobile-phone owner knows, after a year or so the battery starts to fade and the beast needs recharging more frequently.That is troublesome, but a phones batteries can be replaced fairly cheaply or the w

17、hole device traded in for the latest model. An electric car, though, is a much bigger investment. And batteries are its priciest component, representing around 30% of an average mid-size vehicle.To provide buyers with some peace of mind, carmakers guarantee their batteries, typically for eight years

18、 or around 200,000km. Producers, planning to go much further than that, though, are racing to launch “million mile” (1.6m kilometers) batteries. Contemporary Amperex Technology, a giant Chinese firm which produces batteries for a number of carmakers, was said to be ready to start producing batteries

19、 which would last for 16 years or 2m kilometres. Elon Musk has suggested that Tesla,a Californian maker of electric vehicles, has a million-mile battery in the works. And over in Detroit,General Motors is in the final stages of developing an advanced battery which it says has similar longevity (寿命)。

20、Regular fast-charging reduces battery life, as do overcharging and deep discharging. Driving in extremely hot or cold weather does not help either. And battery life will diminish even if you just leave the car in the garage. The real point of a million-mile battery is that the technological advances

21、 required to make it possible will deal with these things as well.Battery technology is improving all the time, and by no means are million-mile batteries the limit of engineers ambition. The next objective is to replace Li-ions liquid electrolytes (电解质) with solid ones. That would allow even longer

22、 driving ranges, which could make a two-million-mile battery an achievable objective. If that day comes,the tables would have been turned. From being the first part of a car to fail, its battery will have become the last.8. The battery problem of mobile phones is mentioned to_.A. show electrical dev

23、ices may have drawbacksB. stress the disturbing battery problem of carsC. call for investment in battery developmentD. compare the function of battery in devices9. What do we know about the million-mile battery plan?A. It is eagerly anticipated by car consumers.B. It is aimed to save repair cost for

24、 customers.C. It targets the longevity of 8 years and above.D. It has drawn the interest of many enterprises.10. What does the author think is the focus of developing the million-mile battery?A. Exploring new materials to construct batteries.B. Guiding users on how to maintain the battery.C. Address

25、ing factors that decrease battery life.D. Researching the principle of battering aging.11. What does the author think of the future of car batteries?A. Promising.B. Unpredictable.C. Concerning.D. Unlimited.DYour best friend that follows you around when the sun comes out - your shadow - doesnt serve

26、an important function like your heart or brain, but what if you could use shadows to create electricity? When using solar panels (电池板) that are powered by light, shadows can be boring because it means electricity cant be created. However, researchers from the National University of Singapore have en

27、gineered a way to create power from the shadows present everywhere.A team of the university created a machine that can collect energy from shadows. It is created by placing a thin coating of gold onto silicon (硅). Like in a normal solar panel, when put in light, the silicon electrons (电子) become ene

28、rgized and the energized electrons then jump from the silicon to the gold. The voltage (电压) of the part of the machine that is placed in the light increases to the dark part and the electrons in the machine flow from high to low voltage. They are sent through an external circuit (外电路) creating a cur

29、rent that can be used to power another machine. The greater the contrast between light and dark, more energy is provided by the machine.The team isworking on improving the performance of the machine, borrowing approaches from solar panels to gather light. Increasing the amount of light the machines

30、can receive allows them to better make use of shadows, as well as developing shadow energy collecting panels that can successfully gather from indoor lighting. The team is also researching the use of other materials other than gold to drop the price of the machine, meaning they would be more cost ef

31、fective and easier to apply in society.Shadows are present everywhere and perhaps one day in the future we will be able to collect energy from them by placing the shadow-effect energy machine around the world in places that have been considered unfit for solar panels to work, or indoors. “A lot of p

32、eople think that shadows are useless,” Tan says, but “anything can be useful, even shadows.”12. What is Paragraph 1 mainly about?A. Your best friend always stays with you after the sunrise.B. The shadow has the same function as the heart and brain.C. Shadows can stop solar panels from creating electricity.D. Researchers have found a way to create power from shadows.13. What is the key working principle of the machine mentioned in the text?A. The silicon produces electricity when it is in the light.B. The gold
