1、课时质量评价（三十二）选择性必修第四册UNIT1主题语境：科技发展与信息技术创新，科学精神，信息安全I .阅读理解（2023 潍坊模拟）Electronics woven （编织）into fabrics promise to open up all kinds of interesting possibilities, from clothing that monitors muscle activity and tracks breathing, to garments that can talk to one another. Developing pliable power sourc
2、es to go with them is an equally important field of research, so scientists at the University of British Columbia have put forward a particularly impressive solution that they say could be the first ever battery that is both stretchable and washable.To develop a battery with such capabilities, the s
3、cientists reimagined the way these devices are put together. Rather than forming a lithium-ion battery packed with hardened materials inside a rigid exterior, the team turned to an alternative chemistry in zinc-manganese （锌镒）dioxide, which is appealing for its low cost and safety. These materials we
4、re ground down into tiny pieces and inset in a polymer （聚合物）to form very thin and stretchable layers.“We went with zinc-manganese because for devices worn next to the skin, its a safer chemistry than lithium-ion batteries, which can produce deadly compounds when they break, “ says Nguyen.The resulti
5、ng battery is flexible and can be stretched to twice its normal length. Meanwhile, it has a specific capacity of 160 mAh g-1 and keeps 75 percent of its capacity over 500 charge and discharge cycles. Impressively, the team found the battery to withstand 39 wash cycles so far.The team is now working
6、to improve the power output and lifetime of the battery, and says the creation has already attracted commercial interest, with the cost expected to be similar to a standard rechargeable battery. They imagine it being put to use in watches and patches that measure vital signs, and in smart clothing t
7、hat does much the same thing.1. Which of the following can replace the underlined word “pliablein Paragraph 1?A. Strong.C. Reliable.B. Multiple.D. Flexible.2. What was a major consideration for introducing zinc-manganese battery?A. Safety.B. Hardness.C. Comfortableness.D. Convenience.3. Which aspect
8、 of the new battery impressed the researchers in Paragraph 4?A. Its washability.B. Its stretch length.C Its massive capacity .D. Its charge speed.4. What is the main idea of the text?A. Electronic clothing is well received.B. Clothing fitted with a new battery is on the way.C. A clothing-friendly ba
9、ttery can be put through wash.D. Electronics woven into fabrics open up possibilities.II.七选五Advantages of Solar PowerAs the name suggests, solar power makes the most of the sunlight and is put to good use for its users. Despite some disadvantages, the advantages of it are so great that they cannot b
10、e ignored. In short, the solar electricity system is an excellent addition to other conventional sources of energy.A solar panel system, when coupled to your electric function, can sufficiently reduce or even cancel your electric bill, yet providing you with the option of using traditional power whe
11、never needed. 2 Its simple to operate as well and this is another advantage. Just ensure that you have the right technology in terms of space use and performance.But perhaps the most widely well-known advantage of solar power is that this is green energy.3 This is a great advantage in today，s world
12、where we need to beconcerned about the high levels of pollution and global warming. Let us all take some responsibility and do something that can clean up our atmosphere to some extent at least. So while on the one hand solar power is clean, on the other hand, it can also greatly reduce the electric
13、ity bill of the users.4 So if you are thinking in terms of installing a solar electric system in your home or commercial property, you should go ahead and do it by all means.And the best news is that the solar power system can be built in your house itself. 5 That is why you need a brochure that can
14、 tell you all about these issues. A. So it is time to take action.B. You cannot ignore the advantages mentioned above.C. When referred to, solar energy is perhaps the best power in the world.D. Also, the flexible system allows you to use it on a wide range of applications.E. But you need to know how and where to make it, where to get the parts affordably etc.F. This power does not cause any pollution, which is why it is such an attraction to many.G. Here are some of the advantages of equipping a solar power system in your home or office.
