1 . Nick Verel, a 53-year-old kidney transplant (肾脏移植) recipient in Ohio, should have been near the top of the list to receive a COVID-19 vaccine (疫苗). Yet like millions of others, he wasn’t having any luck scheduling an appointment. Nick would sit with computers on his lap trying for hours to book an appointment on different sites, which ended up in vain no matter how concentrated he was. “I felt hopeless,” Nick says.
Then he heard about Zwinggi, a 40-year-old mother of three who was helping to secure appointments for vulnerable individuals like Nick. So he messaged Zwinggi on Facebook: Can you help? Thirty-five minutes later, Zwinggi reported back — Nick successfully had an appointment to get the vaccine.
The underlined words “vulnerable individuals” in paragraph 2 refer to those ______.| A．who are too old to book an appointment | B．who need vaccine badly with serious disease |
| C．who have little experience with computers | D．who have little spare time with many kids |
2 . When you think about it, food is an important part of our lives. Family gatherings center around food and the celebration of major life events and milestones involves food in one way or another. The same holds true for us here on the Space Station. Food is important and ends up usually being a topic of discussion for almost every crew.
......
Our food also comes packaged in many ways. But no matter what the form of the food though, you still have the same problem eating it- - you do not want it flying away from you and making a mess when you open it up. In this case a little bit of extra water is extremely helpful. It keeps the food kind of sticking together and to the package and to your spoon. Small things do escape from time to time, but we really try hard to minimize the random flying food problem. That is enough for now! Next time I will write about how to cook in space.
Where is the text most probably taken from?| A．A food magazine. | B．An astronaut’s journal. |
| C．A sci-fi handbook. | D．A space history website. |
SPACE: THE FINAL FRONTIER
“Are we alone? What’s out there?” People have always looked up at the stars and wondered about space. Today, scientists design vehicles to carry astronauts into space to make important discoveries.Space exploration has come a long way, and we now hope to discover other planets that are suitable enough to support life.
Before the mid20th century, most people felt travelling into space was only a dream that could never come true. However, scientists were determined to realise that dream. After many experiments, they succeeded in making rockets that could escape Earth's gravity. On 4 October 1957, the Sputnik 1 satellite was launched by the USSR and successfully orbited around Earth. Afterwards, the USSR focused on sending people into space, and on 12 April 1961, Yuri Gagarin became the first person in the world to enter space. Over eight years later, on 20 July 1969, American astronaut Neil Armstrong stepped onto the moon, famously saying, “That’s one small step for (a) man, one giant leap for mankind.” Following this, there were many more important space achievements. For example, on 5 September 1977, America’s NASA space agency launched Voyager 1 to study deep space, and it still transmits data to this day. And the International Space Station (1998) has provided a continuous human presence in space, with astronauts from many different countries on board.
Although scientists try to make sure nothing goes wrong, accidents can still happen. For example, all the astronauts on the Soyuz 11, Challenger, and Columbia spacecrafts died during their missions. However, while such disasters brought much sadness and disappointment, the desire to explore the universe did not die. This is because people believe in the importance of carrying on space exploration despite the huge risks.
China’s space programme started later than those of Russia and the US, but it has made great progress in a short time. China became the third country in the world to independently send humans into space in 2003, when Yang Liwei successfully orbited Earth in the Shenzhou 5 spacecraft. Then Shenzhou 6 and 7 completed a second manned orbit and the first Chinese spacewalk, followed by the vehicle Jade Rabbit being sent to the moon to study its surface. On 23 July 2020, China sent Tianwen 1 to explore the surface of Mars. It arrived in February 2021 and then sent back lots of valuable information. And from 2021 to 2022, China completed a number of rocket missions to establish its own space station. In 2022, the launch of the Mengtian module signaled the basic completion of the Tiangong Space Station. This modern space station will allow astronauts to conduct many important experiments, greatly furthering our understanding of the universe.
The future of space exploration remains bright. Many countries have plans to further study planets like Mars and Jupiter. Despite the difficulties, scientists hope to make more valuable discoveries that will enable the human race to survive well into the future.

4 . The call for public engagement with the unthinkable is especially germane in this moment of still-uncontrolled pandemic and economic crises in the world’s most technologically advanced nations. Not very long ago, it was also unthinkable that a virus would shut down nations and that safety nets would be proven so disastrously lacking in flexibility.
What does the underlined word “germane” in Paragraph 3 probably mean?
| A．Scientific. | B．Credible. |
| C．Original. | D．Relevant. |
5 . As much as many ALifers hate emphasizing their research’s applications, the attempts to create artificial life could have practical payoffs. Artificial intelligence may be considered ALife’s cousin in that researchers in both fields are enamored by a concept called open-ended evolution (演化). This is the capacity for a system to create essentially endless complexity, to be a sort of “novelty generator”. The only system known to exhibit this is Earth’s biosphere. If the field of ALife manages to reproduce life’s endless “creativity” in some virtual model, those same principles could give rise to truly inventive machines.
What does the word “enamored” underlined in Paragraph 3 most probably mean?
| A．Shocked. | B．Protected. | C．Attracted. | D．Challenged. |
SHANGHAI — A team of Chinese scientists proposed a new artificial intelligence (AI) tool that may help significantly speed up the process of discovering drugs.
The researchers from the Shanghai Institute of Materia Medica under the Chinese Academy of Sciences, described PBCNet, or pairwise binding comparison network, in a study recently published in the journal Nature Computational Science.
The AI tools have been widely used for hunting chemicals that can potentially be translated into drugs, but their efficiency continues to pose a challenge.
The PBCNet is designed for comparing the relative binding affinity among similar ligands (配体) — molecules or ions that bind to larger molecules, according to the study.
A simulation-based experiment showed that active learning-optimized PBCNet may accelerate structure optimization by 473 percent and save computing resources by an average of 30 percent.
The team also established an open-source web service with an easy-to-operate graphical interface for the convenience of users. The tool can be used at pbcnet.alphama.com.cn.
1. pose a challenge2. accelerate structure optimization
3. for the convenience of users
4. What is the news mainly about?
5. According to the article, what can the proposed AI tool do?
Earlier this month, China announced that it was discontinuing its strict dynamic zero-COVID policy to contain the spread of the novel coronavirus. Many people, using 20-20 hindsight, tried to second guess the decision. Many “Monday morning quarterbacks” asked why China didn’t open up earlier and why it would risk putting its economy in a temporary medically induced coma? The answer is: at its core, the mission of the Communist Party of China is to serve the people.
Question: Why did China discontinue its strict dynamic zero-Covid policy?
Answer:

10 . Over the next few weeks, Mika would stop by occasionally. Sometimes, she only stayed for a few minutes; other times, she would wander around my apartment much longer. Each visit brightened me. Mika even helped me connect with some new neighbors, who asked if Mika was my cat. Apparently, Mika visited them as well.
While the lockdown has been awful, I suspect I might not have ever met Mika if it had not happened. But perhaps she came by at this time because she sensed a need for connection on my part.
While dogs are said to be man’s best friend, a good cat can be everyone’s best friend.
What does the underlined word “it” in Paragraph 7 refer to?
| A．The open window. | B．The lockdown. |
| C．A need for connection. | D．A stay with new neighbors. |
