21、For a few seconds on a sunny afternoon last April，renewables broke a record for California’s main electric network，providing enough power to supply 94.5% of demand. The moment was praised as a milestone on the path to decarbonisation(脱碳).But what happens when the sunsets and the winds stop?
Handling the varied power production of renewables will require cheap storage for hours or even days at a time. New types of iron-based batteries might be up to the task.
Many firms are engaged in developing these kinds of batteries. Oregon- based ESS,whose batteries can store energy for between four and twelve hours，launched its first network-scale projects in 2021.Massachusetts-based Form Energy,which raised $ 240 million in 2021，has batteries that store power for up to 100 hours. Its first installation will be a one-megawatt(兆瓦)pilot plant in Minnesota，planned to be completed in 2023.
Both companies rely on batteries that use iron，one of the most abundant materials on the planet. This means that their offerings could eventually be cheaper than other network storage candidates. Form says its batteries could eventually cost just $ 20 per kilowatt-hour，lower than even optimistic predictions for lithium-ion(锂离子)batteries in the next several decades.
There are still challenges to address：iron batteries typically have low efficiency，meaning a good part of the energy that’s put into them can’t be recovered. Unwanted side reactions can also degrade them over time. But if iron-based batteries can be applied widely，at a low enough cost，they could help power more of the world with renewable energy.

D．By explaining definitions.
【3】What do we know about the iron-based batteries in the passage?
A．They are bound to quickly replace all the existing batteries.
B．They are of great help in spite of several unknown weaknesses.
C．They are believed to be applied more widely in the remote areas.
D．They are expected to supply more energy at a much lower cost.

22、Can red TV dramas awaken a strong desire in young people to learn about China’s revolutionary history? The answer is yes. Chinese TV drama Awakening Age, which narrates the story of how the Communist Party of China (CPC) was founded in 1921, ended several months ago, but it remains a hot topic on social media, where discussion shows that it has played a positive role in educating young people about China’s revolutionary history.
The TV series celebrating this year’s 100th anniversary of the founding of the CPC has won high praise online. The stories of the young people in the drama — who gave everything, even their lives, to the revolution — have touched a large number of viewers. The storytelling in the show has also been hailed by viewers for successfully showing the depth of the CPC’s history and spirit, as well as the warmth of China and every family in the country.
Many audiences were inspired to find background information about the series and commented that this is their first time to voluntarily learn the history about the founding of the Party and the country. “I read many of Lu Xun’s novels such as A Madman’s Diary when I was in elementary school, but I couldn’t understand why he wrote them or the angry feelings hiding in the characters. After watching the drama, I read these novels again and found that I can now understand what they wanted to convey to readers,” said Li Lin, a 29-year-old viewer.
Some school teachers have been showing video clips from the series in classes to arouse students’ interest in the time period and help them learn more about history. A junior high school teacher from Taiyuan, in north China’s Shanxi Province, said that this has proven effective as some students told her after class that the show had left a strong impression on them.
【1】What can we know about Awakening Age according to paragraph 1?
A．It inspired many students to join the CPC.
B．It described the establishment of the CPC.
C．Many famous actors starred in the drama.
D．It reached the most viewers among TV series.
【2】Which of the following could replace the underlined word “hailed” in paragraph 2?
A．Recorded
B．Recalled
C．Proven
D．Praised
【3】What did watching the drama help Li Lin acquire?
A．A firm decision to be a good writer.
B．The strong desire to be a CPC member.
C．A better understanding of related literature works.
D．The determination to be a successful actor.
【4】What words could best describe the drama?
A．Instructive and touching.
B．Historical and delightful.
C．Informative and entertaining.
D．Imaginative and inspiring.
23、The bacteria which inhabit (栖居于) human beings, particularly the guts (肠道) of those beings, have been found in recent years to be important for fighting off diseases. That something similar happens in other animal species is doubtless true as well. But work by Seon-Woo Lee at Dong-A University and Jihyun Kim at Yonsei University, both in South Korea, suggests that it is not only animals that benefit from such bacterial protection. Their study, just published in Nature Biotechnology, shows that plants do, too.
Crop plants of the nightshade family, such as potatoes and tomatoes, are not immune to a soil bacterium called Ralstonia solanacearum. This enters their roots and spreads through their water-transport systems, causing them to wilt (枯萎). Infection is usually deadly; the disease costs potato farmers alone $1bn a year. A variety of tomato called Hawaii 7996, however, does not suffer from such bacterial wilt. Dr Lee and Dr Kim wondered if the explanation for this exceptionalism lay with other bacteria in the soil.
To test that idea, they grew crops of Hawaii 7996 and a second tomato variety called Moneymaker. Once the plants were established, the researchers analyzed bacteria in the soil around the plants’ roots and found systematic differences that depended on which tomato variety was growing. This observation made their explanation reasonable and likely to be true.
They then transplanted some of their Moneymaker plants into soil that had previously supported Hawaii 7996s, and some of the Hawaiian plants into soil that had been home to Moneymakers. As controls, they similarly uprooted (拔起) individuals of both varieties and replanted them in soil once occupied by the same variety. That done, they exposed all of their plants to R. solanacearum and monitored them over the course of 14 days.
They found the disease progressed almost 30% more slowly in Moneymaker plants grown in “Hawaiian” soil than it did in those Moneymakers that had been replanted into their own soil. In contrast, it progressed rapidly in the normally resistant Hawaiian variety when this was transferred into Moneymaker soil.
Further study revealed that credit for this disease resistance went to a single type of soil bacterium, called TRM1. Dr Lee and Dr Kim therefore cultivated (培育) this bug in their laboratory and used it to treat soil into which Moneymaker plants were then planted. When these were infected with R. solanacearum they proved more resistant than others that had been planted into untreated soil as controls.
These findings suggest to Dr Lee and Dr Kim that the roots of Hawaii 7996 are releasing compounds (化合物) which encourage the growth of TRM1. What those compounds are has yet to be determined. The two researchers’ work, however, seems to suggest something constructive.
【1】The author mentions the bacteria inhabiting human beings to introduce ___________.

25、On my way home, I saw a poor old man selling soaps. I was moved by his condition—perhaps he was the only one _______ his family? But I soon shook off the _______ —there’s nothing I can really do for him.
Just then, a lady went up and bought every bar of soap he was carrying. The old man’s eyes lit up and he left happily.
The woman, on the other hand, crossed the road and _______ the bag full of soaps on the street with a sign saying “For Free”. Then she boarded the same bus as I did and took the seat next to mine. The curious incident _______ me so I couldn’t help but ask her about the strange act.
“Excuse me, may I ask why you did that near the bus stop?” I said.
