It captures energy from the cold night sky.A prototype （雏形）of the device produced enough electricity at night to power a small light bulb. A bigger version might one day light rooms or charge phones. It could also power electronics in remote or low-resource areas that lack electricity.The device makes use of the temperature difference between the earth and outer space to create electricity. As long as one side of it is cooler than the other, the generator can produce electricity. The cooler side faces the sky and is attached to an aluminum plate. That plate is sealed beneath a transparent cover and surrounded with insulation （隔热材料）to keep out heat. The bottom of the generator is attached to an exposed aluminum （铝）plate. That plate is warmed by the local air. At night, the top plate can get a couple of degrees Celsius cooler than the bottom of the generator.Researchers tested a 20-centimeter prototype one clear December night in Stanford University, California. The generator produced up to 25 milliwatts of power per square meter of the device. That was enough power to light a small light emitting diode （发光二极管），or a LED bulb. Further improvements might increase its production to at least 500 milliwatts per square meter. The system might need more insulation around the cool, top plate to do that.“The device could also help power remote weather stations or other environmental devices,” says Aaswath Raman. He is a material scientist who works on the device at the University of California, Los Angeles. “This may be useful in polar regions where people can't see sunlight for months,” Raman says. "If you have some low-power devices and you need to power them through three months of darkness, this might be a way.”5．What does the author mainly talk about in Paragraph 3?A．Application fields of the device.B．The developing process of the device.C．The working principle of the device.D．Significant effects of the device.6．How can researchers make the device produce more electricity?A．By putting more insulation around the top plate.B．By using it in extremely cold and clear nights.C．By attaching the bottom plate to a warm plate.D．By covering the top plate with a transparent lid.7．What’s Raman’s attitude to the new device?A．Doubtful. B．Hopeful. C．Negative. D．Ambiguous.8．What could be a suitable title for the text?A．A Device Using the Cold Night Sky to Produce ElectricityB．A Device Bringing New Hope for Those in the Cold NightC．The Differences Between a Solar Panel and a New DeviceD．The Temperature Difference between the Earth and Outer Space语法填空阅读下面材料，在空白处填上适当的内容（1个单词）或括号内单词的正确形式。One Japanese company said a “smart” mask is ready to improve for people ____1____(wear) face coverings.The use of the face masks plays a key role in reducing spread of the coronavirus(冠状病毒). ____2____, masks and other kinds of coverings can affect the quality of communication between wearers.It can be more difficult to hear voices through the coverings. Many business and public spaces also have social distancing rules in place, which makes it harder for people   ____3____(hear) and understood.The wearable electronic device is designed to solve the problem.The company calls its ____4____(invent) the “c-mask”.

The device can also translate a person’s voice into eight other languages.The mask will ____9____(hopeful) be put into the market next year. The designer says he has received strong interest in the product from some potential ____10____(customer).培优第三阶——高考沙场点兵读后续写阅读下面短文，根据所给情节进行续写，使之构成一个完整的故事。You love your smartphone. It keeps your email readily accessible, and it helps you to stay connected to friends near and far. It’s harmless, right?Wrong. Smartphone addiction is a real concern, especially as people become increasingly dependent on gadgets to conduct daily activities. If you fear your devotion to your smartphone is bordering on addiction, here are eight signs. If you had some of them, it might be time to seek help:· You text people who are in the same room with you.· Your phone goes everywhere with you-even the bathroom.· You sleep with your phone.· You don’t know how to turn your phone off.· Your self-esteem is tied to how many notifications you get.· You panic if your phone is out of sight.· You’d rather be late than arrive without your phone.· You can’t stop peeking at the screen, even during a movie or your favourite TV show.What smartphone addiction looks likeSome of those signs may seem very silly, but they are real indicators that your dependence on your smartphone is reaching critical levels.An addiction has no real danger unless they are disruptive to your life. But that doesn’t mean a strong attachment to your smartphone is completely harmless. Difficulty in concentrating, poor sleep, and increased anxiety-not to mention damage to interpersonal relationships and communication skills-have all been linked to smartphone overuse.How to take your life backIt’s easy to shrug off smartphone addiction as a silly overreaction, but if you identify with two or more of the signs listed above, you may want to consider cutting back.Here are some easy ways to use your smartphone properly:Set limitsStart by setting some guidelines to help you manage your usage.______________________________________________________________________________________    __________________________________________________________________________________________________________________________________________________________________________________________Watch your feelings    _____________________________________________________________________________________    ___________________________________________________________________________________________________________________________________________________________________________________________Find other comforts to replace smartphones______________________________________________________________________________________  ____________________________________________________________________________________________________________________________________________________________________________________________注意:1. 所续写短文的词数应为 150 左右；2. 至少使用 5 个短文中标有下划线的关键词语；3. 续写部分分为三段，每段的开头语已为你写好；4. 续写完成后，请用下划线标出你所使用的关键词语。
