21、Lithium-ion(锂离子)batteries are the current front-runners for storing renewable energy, but their components can be expensive. Zinc(锌)batteries are easier on the wallet and the planet, but lab experiments are now pointing to ways around their primary drawback:They can’t be recharged over and over for decades.
The need for grid-scale(电网规模的)battery storage is growing as increasing amounts of solar, wind, and other renewable energy come online. This year, America is committed to making the American electricity grid carbon-free by 2035. To even out dips in supply, much of that renewable power will have to be stored for hours or days, and then fed back into the grid. For California alone, it wants to deploy(部署)more than 8800 megawatts of rechargeable batteries by 2026, and last week, the governor of California proposed $350 million in state funding to develop long-duration energy storage technologies. “That trend will not go down. It will only continue to grow,” says Mark Baggio, vice president for business development at Zinc8 Energy Solutions, a zinc battery producer.
“For power storage, Lithium-ion is the 800-pound gorilla,” says Michael Burz, CEO of EnZinc, a zinc battery startup, “but lithium, a relatively rare metal that’s only mined in a handful of countries, is too scarce and expensive to back up the world’s grids. We need an alternative to lithium. Zinc batteries may be one of the options.”
Non-rechargeable zinc batteries have been on the market for decades. More recently, some zinc rechargeable batteries have also been commercialized, but they tend to have limited energy storage capacity. Another technology, zinc flow cell batteries, is also making big steps. But it requires more complex pumps and tanks to operate.
So, researchers are now working to improve other varieties including zinc-air cells. They say although it’s urgent, there is a long way to go before they find a solution.
【1】What do we know about grid-scale battery storage?
A.It lacks financial support.
B.It has crucial breakthroughs.
C.It meets the public demands.
D.Its market is huge.
【2】What is Michael Burz’s attitude to zinc batteries for energy storage?
A.Skeptical.
B.Supportive.
C.Conservative.
D.Disappointed.
【3】What does paragraph 4 mainly tell us about Zinc batteries?
A.Their improvements.
B.Their popularity.
C.Their functions.
D.Their disadvantages.
【4】Which can be the best title for the text?
A.Carbon free:a long-term goal to achieve
B.Zinc batteries:a possible solution to power storage
C.Renewable energy:the unlimited resource of power
D.Lithium-ion batteries:the front-runners for storing energy
22、Tech giants Apple and Google are teaming up to create a system that would let smart phone users know when they've come into contact with someone who has COVID-19.
The technology would rely on the Bluetooth signals that smart phones can both send out and receive 1aperscn tests positive(阳性) for COVID-19, they could inform public health authorities through an app. Those public health apps would then warn anyone whose smart phones bad come tear the infected person's phone in the previous 14 days. The technology could be used on both Google Android phones and Apple iPhones.
The companies insist that they will preserve smart phone users' privacy and their technology will be used only by public health authorities to trace the spread of COVID-19. Smart phone users can choose to use it. The software will not collect data on users' physical locations or their personally identifiable information. People who test positive would remain unknown to the public, both to the people who came in contact with them and to Apple and Google. “Privacy is of greatest importance in this effort,” the companies said in a joint statement.
The American Civil Liberties Union has warmed that using cellphone data to handle the pandemic carries risks of “destruction of privacy”. In a statement on Friday, ACLU cyber security counsel Jennifer Granick said, The system also can't work well if people don’t trust it”. She said that the joint Apple and Google project “appears to reduce the worst privacy risks, but there is still room for improvement.” She added that the contact tracing app should be used only for public health purposes and only for the duration of this pandemic.
Public health officials say the contact tracing -finding people who have been in contact with an infected person will be a key step in lifting shelter in-place restrictions.
It would allow people who are known to have been exposed to the virus to isolate themselves, while letting others recover normal activities.
【1】What is the main purpose of the passage?
A.To advertise for public health.
B.To introduce a contact tracing system.
C.To warn the public of risks of COVID-19.
D.To raise people's awareness of privacy protection.
【2】What do the companies promise to do in particular?
A.Warn people who test positive.
B.Protect infected people's privacy.
C.Work with public health authorities.
D.Collect data on users physical locations.
【3】What does the underlined sentence in Paragraph 4 suggest?
A.Public health issues are traced accurately.
B.Only people's trust influences the system.
C.The system is at the risk of being destroyed.
D.Jennifer thinks the system should be better.
【4】The system is mainly designed to .
A.ensure infected people's recovery
B.guarantee people's normal activities
C.help prevent the spread of COVID-19
D.encourage all the people to isolate themselves

26、阅读下面材料,根据其内容和所给段落开头语续写两段,使之构成一篇完整的短文。
Last Saturday I received a call from my close friend, Peter. He asked me to help with his group who provided musical performances at the local hospitals. At first I was unwilling to go because of my unfinished homework, but I was finally persuaded into helping out this one time, which turned out to be an unforgettable and fruitful experience.
That evening, I was picked up by Peter and went to a local hospital with him, taking my guitar and hoping I could sing some solo songs with his musical group.
An extremely large hospital came into our sight. When guided into the hall, we were shocked to find so many patients and staff there. What we saw next aroused our sympathy. Some patients were in wheelchairs or with their arms in bandages, while others were with their drips attached. Some faces were rather pale; some wore worried expressions; some walked as fast as they could. Maybe their days seemed to be dull during the period of their treatment, so our coming brought some color into their lives. Seeing their happy faces, I thought it was worthwhile to join Peter's group.
Among the audience, I spotted one particular young girl aged about 16, who was wearing a head scarf and appeared to be more delighted than the others. When we started our performance, excitement filled the hall. Peter mentioned to me that the young girl I had noticed earlier was singing along with all our songs quietly to herself. At a break, out of curiosity, I asked one of the nurses about the girl. She said that the girl suffered serious burns and was under treatment and that she was a bit down these days, but our performance had lifted her spirits. Our songs moved all the people present. They all cheered for us, including the young girl and we were inspired. Facing these lovely people, we really wanted to do more.
注意:1、续写词数应为150左右;
2、请按如下格式在答题卡的相应位置作答。
We asked the girl if she would like to sing with us.
