21、Here are some superheroes in the fight against COVID-19 (新冠肺炎). Let’s come close to them and remember them.
Zhong Nanshan(1936.10—)
He is one of the famous medical scientists in the 21st century. Dr Zhong Nanshan was the first to tell the public that the virus could be transmitted from person to person. He is a good doctor in the countrymen’s eyes and respected by all Chinese people.
Li Lanjuan (1947.09—)
When COVID-19 broke out, she suggested that Wuhan should be locked down immediately to prevent the spread of the disease. She headed for Wuhan and took an active part in the battle. Now, she still receives patients every day.
WangYong(1985.12—)
As a delivery (快递) driver, he volunteered to support the medical staff in Wuhan during the epidemic (疫情). He tried his best to keep life going for the doctors and nurses. Time magazine has put on its cover, presenting the courage and hard work of common people.
Li Wenliang (1985.10—2020.02)
He is the first doctor to warn people how dangerous the virus could be at the end of last December, so people call him the “whistle-blower (吹哨人)”. Because of COVID-19 he lost his life on February, 2020. People across the country were sad to hear about his death.

22、Microplastic pollution has been detected in human blood for the first time, with scientists finding the tiny particles(微粒) in almost 80% of the people tested. The discovery shows the particles can travel around the body and may live in organs.
The impact on health is as yet unknown. But researchers are concerned as microplastics cause damage to human cells in the laboratory and air pollution particles are already known to enter the body and cause millions of early deaths a year.
Huge amounts of plastic waste are left in the environment and microplastics now pollute the entire planet, from the top of Mount Everest to the deepest oceans. People were already known to consume the tiny particles via food and water as well as breathing them in, and they have been found in the faeces (排泄物) of babies and adults.
The scientists analysed blood samples from 22 healthy adults and found plastic particles in 17. Half the samples contained PET plastic, which is commonly used in drinks bottles, while a third contained polystyrene, used for packaging food and other products. A quarter of the blood samples contained polyethylene, from which plastic carrier bags are made.
“Our study is the first indication that we have polymer particles(聚合物颗粒) in our blood — it’s a breakthrough result,” said Prof Dick Vethaak, an expert at Vrije Universiteit Amsterdam in the Netherlands. “But we have to extend the research and increase the sample sizes, the number of polymers assessed, etc.” Further studies by a number of groups are already under way, he said.
“It is certainly reasonable to be concerned,” Vethaak said. “The particles are there and are transported throughout the body.” He said previous work had shown that microplastics were 10 times higher in the faeces of babies compared with adults and that babies fed with
plastic bottles are taking millions of microplastic particles a day.
Vethaak acknowledged that the amount and type of plastic varied considerably between the blood samples. “But this is a pioneering study,” he said, with more work now needed. He said the differences might reflect short-term exposure before the blood samples were taken, such as drinking from a plastic-lined coffee cup, or wearing a plastic face mask.
“The big question is what is happening in our body?” Vethaak said. “Are the particles retained in the body? Are they transported to certain organs, such as getting past the blood-brain barrier? And are these levels sufficiently high to cause disease? We urgently need to fund further research so we can find out.”
【1】What could be inferred from Paragraph 2?
A．Air Pollution particles can cause death eventually.
B．Microplastics can be deadly to humans.
C．There is no evidence that microplastics harm human cells.
D．Microplastics can travel throughout body and damage organs.
【2】What can we learn about microplastics from Paragraph 4?
A．They are found in most people.
B．Polyethylene found in blood samples might be taken from drinks bottles.
C．A quarter of the blood samples contained PET particles.
D．Half of the microplastics in the blood samples were likely introduced by drinking from plastic containers.
【3】According to Paragraph 5, what was Prof Dick Vethaak’s attitude towards their findings?
A．Doubtful.
B．Negative.
C．Excited.
D．Depressed.
【4】The underlined part “this is a pioneering study” in Paragraph 7 probably means ________.
A．we are the pioneers in the field of plastic research
B．we need more blood examples and more work to do
C．we are entering a whole new field of research
D．this is an extremely important study
【5】Which section of the newspaper may this article be found in?

23、I'd spent decades telling my girls that their bodies were a means to a long and satisfactory life, not objects to be admired because of how they look. I told them that good health and the energy to enjoy life should be their ultimate goals, not fitting into society's preconceived ideas of what is beautiful.
This year I'm sixty years old. I appear much older than before. This aging body of mine is not the one I expected to have. Looking at the old, fat, wrinkled woman in the mirror, I begin to complain about it. I've actually spent a lifetime focusing on my flaws, constantly complaining about my less-than-perfect self. As I was complaining yet again, my younger daughter told me, “Mom, stop. Stop putting yourself down. This is the body you live in now. It's beautiful because it's yours.” If I'm unwilling to accept my aging self with grace and dignity, how can I possibly expect my girls to do the same when they face these same physical changes?
And then, I learned that a friend of mine, the same age as me, died. At her funeral, her three heartbroken daughters spoke of their mother's devotion, wisdom, and compassion. They never said a single word about her appearance though her body had melted away during her last months. It didn't matter. I left that funeral desperate to hold my own girls in my arms, to kiss them and tell them how much they mean to me , and to promise that I will do better, be better—for them as well as for myself.
And so, to honour the memory of my dear friend and to set a good example to my beloved girls, I promise to love my aging body, and celebrate the gift of being alive.

24、A recent issue of National Geographic magazine described one of the wonders of the earth, the tiny silver ants of the Sahara desert. These ants live in areas where temperatures reach up to 57℃, as the article described it, an environment “where shoes melt.”
These tiny ants are amazing. In the Sahara desert, where most creatures avoid going out in the middle of the day to avoid high temperatures,the Saharan silver ants have evolved(进化)a number of adaptations to do just that. Scientists have discovered that several unique features of the Saharan silver ants permit them to grow well in a scorching climate.
These ants have longer legs than other ants, which keep their bodies critically greater distance away from the hot desert sand. The ants run 108 times the length of their own bodies every second at a speed of just over 3kph. And they keep track of the position of the sun, so that they always know the most direct route back to the nest, thus lowering their time spent in extreme heat. Their bodies produce proteins that resist heat. Some other creatures produce such proteins after they come in contact with extreme heat. But since the silver ants only exit the nest for a few minutes at a time — not long enough for the protein to take effect — they produce the protein while still in the nest before they go out, or they would die before the protein could take effect.
Researchers also discovered that the ants are covered on their tops and sides with the uniquely triangular(三角的)shape of the silver hairs,which enable them to dissipate(消散)heat.The hairs help an ant's body exchange its heat to a cooler area, even under full sun conditions. This discovery inspired the scientists, for it could lead to new materials and paints that can be applied to rooftops or cars to keep them cool. And it is also expected to be applied in clinical care, wearable devices,protective clothing and other fields.
【1】What does the underlined word “scorching”in Paragraph 2 mean?
A．extremely chilly
B．extremely cool
C．extremely mild
D．extremely hot
【2】Which statement can be inferred from the text?
A．The Saharan silver ants' hairs act like a tiny air-heating system.
B．The Saharan silver ants are born with the ability to track the moon.
C．The Saharan silver ants' adaptations to the desert are to be discovered.
D．Inspiration from the Saharan silver ants will bring up more new inventions.
【3】When do the Saharan silver ants produce the protein that resists heat?
A．After coming in contact with extreme heat.
B．Before traveling in the sun.
C．While running under full sun condition.
D．After coming back to the nest from outside.
【4】What would be the best title for the text?
A．Small Ants Make a Big Difference
B．Small Ants Hunt for Food Easily
C．Small Ants Survive in the Saharan Desert
D．Small Ants Jump the Fastest in the World

26、Directions: Read the following three passages. Summarize the main idea and the main point(s) of the passage in no more than 60 words. Use your own words as far as possible.
Why Screen Time Isn’t Always Bad
For the past few years, I have been researching the effects of one type of screen time on our behaviour: playing video games. It’s easy to see why video games are often dismissed as something harmful. Players seem absorbed by the action on the screen, as if the rest of the world doesn’t exist. Without further context, it’s hard to see games as anything other than digital junk food.
But context matters, and understanding the experience of the players can give us new understanding. Video games are an inherently social experience: they’ve been designed as cooperative. Take Mine-craft, for example. It does bring people together in all sorts of ways. Some play to connect with their friends, others share in the creative experience of building something monumental, and it’s even been used as an interactive tool to teach students basic chemistry. Elsewhere, studies have shown that video games can be used as a therapy to help soldiers overcome PTSD, and to help children with cancer stick to treatment.
As for the supposed negative aspects of video games, the story is largely the same. Studies that show a link between violent games and aggressive behaviour are often picked up in the news over other, more meaningful studies. Part of the problem is that it’s remarkably hard to test for aggression in the lab, and there’s also a great deal of flexibility in the way that researchers can analyse their data. But where the best methods are used, evidence suggests that playing violent games has fairly negligible effects on our behaviour.
Our understanding of the behavioural effects of video games - and screens more generally - isn’t yet complete. After all, these technologies are a relatively recent addition to our lives. Like many things, we can use them in good ways, and we can use them in bad ways. It’s up to us, as a society, to use their potential for good.
