21、 It was a red-letter day in the history of medicine—“Target Zero Day”, May 8th, 1980, marking the complete removal of smallpox, a terrifying disease. It was untreatable but, luckily, it turned out that vaccination(接种疫苗) provided good protection— and that mass immunization(免疫) could wipe out the smallpox virus by blocking its spread.
According to legend, vaccination was invented by Dr Edward Jenner. Jenner showed that healthy children vaccinated with cowpox, a mild infection of cattle, could not catch smallpox. He was supposedly inspired by a comment from a local milkmaid, but there is evidence that the idea came from a medical friend, John Fewster, who had experimented with cowpox. Nevertheless, Jenner deserves credit for introducing vaccination into the medical mainstream with his paper published in 1798.
In 1966, 160 years after the prediction that vaccination would clean off the disease, the World Health Organization launched its Smallpox Eradication Programme. This heroic 11-year drive was directed by two’ American public health doctors, DA Henderson and Bill Foege. Their hardships were enormous. One WHO official even promised to eat a tyre if smallpox was removed. Henderson promised to send him the tyre and wished him good appetite. But Henderson and Foege’s hard work paid off— three years after the last smallpox case was informed (to make sure no outbreaks had been missed) Target Zero Day was declared.
40 years on, why should we remember Target Zero Day? First, to celebrate victory of preventative medicine and freedom from a cruel disease. Then, we must remember the victims of smallpox. It had previously killed 1 in 12 worldwide. In 1914, a Canadian professor warned against forgetting smallpox, which was fast disappearing from North America. It went on to kill at least another 250 million people— three times more than both world wars combined. Target Zero Day also reminds us of undefeated infections, including polio, measles, malaria, and of course the coronavirus Covid-19. Let’s recognize Target Zero Day for what it is：a milestone in world history and a monument to the art of the possible.
【1】What inspired Jenner to invent the vaccination?
A.A medical friend. B.A local milkmaid.
C.Cattle. D.Children.
【2】What is the writer’s purpose of mentioning the WHO official’s promise?
A.To introduce the support from the WHO.
B.To stress the importance of good appetite.
C.To suggest the difficulty in removing smallpox.
D.To show his determination to carry on the drive.
【3】From the last paragraph we can infer that _______.
A.Covid-19 will be conquered soon
B.world wars are worse than infections
C.Canadians benefit from the vaccine most
D.smallpox is a terrifying disease
【4】What message does the text convey?
A.Every dog has his day.
B.A good beginning is half the battle.
C.A trouble shared is a trouble halved.
D.Nothing is impossible to a willing heart.
22、 After a long week, sometimes a short getaway is in order. However, deciding which destination to travel to can be tough when you only have a weekend to spend. To help you choose the right trip, U. S. News considered factors like accessibility, affordability and entertainment options, as well as reader votes, to determine which cities offer the best setting for a weekend away.
New York City
Visitors can reach New York City by train, plane or automobile, so weekend getaways are easy. Plus, abundant attractions indoors (like museums and Broadway shows) make unpredictable weather no problem. For history, take the ferry to Ellis Island or the Statue of Liberty.
Chicago
Chicago’s diverse neighborhoods and abundance of can’t-miss sights make it a great weekend vacation, spot. On warmer days, take a photo of yourself in front of “The Bean” and go aboard an architecture river cruise. Meanwhile, museums like the Art Institute of Chicago and the Field Museum are wonderful places to escape winter s biting temperatures.
Toronto
Cross Lake Ontario to our northern neighbor for an urban escape. It’s hard to see all of Toronto in just a few days, but first- timers can hit the high points, such as the CN Tower, the St. Lawrence Market and the Hockey Hall of Fame. Save an evening to explore the Distillery District.
Washington, D. C.
Not only is America’s capital full of free attractions, but many of them are concentrated on the National Mall, making it easy to see the Lincoln Memorial, the Washington Monument and other highlights in just a few days. While visiting, don’t miss out on the popular weekend brunch scene -just remember to make reservations in advance.

23、Temidayo Adedokun, 31, who was born in Nigeria and now is working in America, became pregnant with her first child. She couldn’t hide her joy, and couldn’t wait to shop for baby clothes with traditional African prints that she grew up wearing.
“I was super surprised that I failed to find affordably priced African aesthetic(美学的) products that were designed from an authentic place, ” Temidayo said.
Temidayo decided to take matters into her own hands. At first, she focused on creating clothes just for her baby. But then, she put some of them on a website to see what happened.
The feedback she got gave her just enough confidence. She figured she’d make the baby clothes an after-work side business to her full-time position as a lawyer in Oakland, California, until one day she was told she was given a boot. Once again, she needed to make her own choice. That’s when she decided to make it a full-time job.
“I had to evaluate: Am I going to search for another job I don’t have a great desire for?” she said. “Or am I going to take this as a chance I’m not sure about myself? After all, I’m not familiar with this field. What if something unexpected happens? However, for the symbols of children’s clothing in my heart, I threw myself into it. So I chose the latter. ”Then, in March 2020, Temidayo officially announced her own brand: Ade + Ayo.
Since then, Temidayo has received much praise from other African parents informing her that her clothes help them start having conversations with their kids about what they’re wearing and allow them to show their children the treasures handed down by their ancestors. And, for those who aren’t African, her clothes have been a way for parents to introduce their kids to a new and colorful world. “I feel very blessed to be able to be doing this,” she said.
【1】How did Temidayo feel after trying to buy African aesthetic clothes?
A．Pleased.
B．Confident.
C．Stressful.
D．Disappointed.
【2】What does the underlined phrase “given a boot” in paragraph 4 mean?

D．Accused.
【3】What did Temidayo originally think of her creating her own brand?
A．It was informal.
B．It was profitable.
C．It was risky.
D．It was trendy.
【4】How can we evaluate Ade + Ayo?
A．It’s created African aesthetics.
B．It’s spread authentic cultures.
C．It’s targeted overseas Africans.
D．It’s inspired people’s creativity.
24、Last year scientists reported using a neural implant (神经植入物) in a man’s brain to restore his ability to communicate. The man has been partially paralyzed and unable to produce comprehensible speech since suffering a severe stroke. It is the latest advance in the exploding field of brain-computer interfaces (接口), or BCIs, which allow computers to read information out of a living brain.
Brain-computer interfaces are possible because of two facts. The first is that your brain contains hundreds of tiny maps. Each represents specific features of your physical feelings and intended actions. And crucially, the basic set of brain maps and their locations within the brain are very similar across individuals.
Thanks to their specialized functions and universal locations, brain maps are ideal entry points for BCI technologies. Picking up signals from a brain map is only the first step in making a useful BCI. Although the location of a brain map is the same across individuals, the details — what patterns of activity within the map mean — differ from person to person. In a sense, the unique features of your specific brain maps serve as a kind of encryption (加密), safeguarding your specific thoughts and feelings from would-be spies.
That brings us to the second fact that makes BCIs possible. Thanks to advances in machine learning, scientists have developed programs that can learn to recognize key patterns in a vast sea of numbers. They train these programs to decode (解码) brain signals by feeding them tons of examples. Researchers developing BCIs often create such examples by instructing an individual to think specific thoughts at specific times, creating a neural curriculum for the program to learn from.
While the universal features and locations of brain maps make them obvious entrances for BCIs, the unique features of your brain maps tend to protect them from spying eyes. In cases where BCIs have successfully read specific thoughts or intentions from a brain, it has been with the permission of the individual whose brain was being read. But there are surreptitious ways to train decoders on your brain without your knowledge. This can happen if your neural data falls into the hands of companies with detailed information about your activities.
Like all technologies, brain-computer interfaces are not necessarily good or bad. Yet while harvesting the benefits of BCIs, we need to ensure that we have the means to protect ourselves from corporations with every motive to take advantage of this technology for their financial gain.
【1】What can we learn about brain maps?
A．They carry unique messages.
B．They can process encrypted signals.
C．Their functions vary from person to person.
D．Their locations reveal human thinking patterns.
【2】What can we infer from the passage?
A．BCIs can boost brain signals dramatically.
B．BCIs could help recover from brain injuries.
C．Machine learning enables BCIs to read mind.
D．The decoding of brain may be affected by BCIs.
【3】What does the underlined word “surreptitious” in Paragraph 5 probably mean?
A．Secure.
B．Stable.
C．Standard.
D．Secret.
【4】What does the passage mainly talk about?
A．The future trend of BCIs.
B．The potential risks of BCIs.
C．The working principle of BCIs.
D．The general applications of BCIs.
