21、 For years, the U. S. has experienced a shortage of registered nurses. The Bureau of Labor Statistics projects that while the number of nurses will increase by 19 percent by 2022, demand will grow faster than supply, and that there will be over one million unfilled nursing jobs by then.
So what's the solution? Robots.
Japan is ahead of the curve when it comes to this trend. Toyohashi University of Technology has developed Terapio, a robotic medical cart that can make hospital rounds, deliver medications and other items, and retrieve records. It follows a specific individual, such as a doctor or nurse, who can use it to record and access patient data. This type of robot will likely be one of the first to be implemented in hospitals because it has fairly minimal patient contact.
Robots capable of social engagement help with loneliness as well as cognitive functioning, but the robot itself doesn't have to engage directly—it can serve as an intermediary for human communication. Telepresence robots such as MantaroBot, Vgo, and Giraff can be controlled through a computer, smartphone, or tablet, allowing family members or doctors to remotely monitor patients or Skype them, often via a screen where the robot's ' face' would be. If you can't get to the nursing home to visit grandma, you can use a telepresence robot to hang out with her. A 2016 study found that users had a "consistently positive attitude" about the Giraff robot's ability to enhance communication and decrease feelings of loneliness.
A robot's appearance affects its ability to successfully interact with humans, which is why the RIKEN-TRI Collaboration Center for Human-Interactive Robot Research decided to develop a robotic nurse that looks like a huge teddy bear. RIBA (Robot for Interactive Body Assistance), also known as ‘Robear', can help patients into and out of wheelchairs and beds with its strong arms.
It's important to note that robotic nurses don't decide courses of treatment or make diagnoses (though robot doctors and surgeons may not be far off). Instead, they perform routine and laborious tasks, freeing nurses up to attend to patients with immediate needs. This is one industry where it seems the integration of robots will lead to collaboration, not replacement.

22、A new underwater camera developed recently at Massachusetts Institute of Technology (MIT) could have many uses, including climate modeling.
More than 95 percent of the earth’s oceans have never been observed. This means we have seen less of our planet’s ocean than we have the far side of the moon or the surface of Mars. What is preventing widespread undersea exploration? The answer is the high cost of powering an underwater camera for a long time.
MIT researchers have taken a big step to solve this problem. They developed a new underwater camera. The camera is about 100, 000 times more energy-saving than other undersea cameras. It takes color photos, even in dark underwater environments, and sends images through the water. Most importantly, it can work for a very long time by powering itself.
The camera turns energy from sound waves traveling through water into electrical energy. It uses the electrical energy to power its imaging and communication equipment. After capturing images in the ocean, the camera also uses sound waves to send them to a receiver. The camera doesn’t need a power source, so it could run for weeks on end. And this allows scientists to search more parts of the ocean. The camera could also be used to capture images of ocean pollution.
“We can use the camera to help us learn what is happening to the climate. Personally, this is one of the most exciting things about the camera. We are building climate models, but we need to know more about the ocean. This technology could help us build more detailed climate models and better understand how climate change impacts the underwater world,” says Fadel Adib, director of the Signal Kinetics group in the MIT Media Lab.
【1】Why does the author mention the moon and Mars?
A．To explain the difficulty in scientific research.

【2】Why is the new camera considered a big step?
A．It takes over 100,000 photos.
B．It works for a long time underwater.
C．It costs little to build such a camera.
D．It functions well in dark environments.
【3】What is the main idea of the fourth paragraph?
A．How the camera works.
B．What the camera looks like.
C．How the camera moves underwater.
D．Which parts of the ocean the camera works in.
【4】What can the camera help scientists do according to Fadel Adib?

23、A hungry badger (獾) searching for food seems to have uncovered what turned out to be hundreds of Roman coins in a Spanish cave, according to a new study.
Archaeologists (考古学家) first discovered several coins laying on the ground at the entrance to a small cave in the woodlands outside Grado in northern Spain in April 2021. The researchers suspect that the coins were unearthed by a badger from a nearby den (兽窝) after a heavy snow which made it harder for animals to find food. The hungry badger probably got into the cave looking for food but came across the coins instead.
After fully exploring the cave, researchers collected 209 coins dating to between the third and fifth centuries A.D. “To date, this is the largest amount of Roman coins found in n cave in northern Spain,” the researchers wrote in their paper. They described the discovery as an “exceptional find”.
In the late 1930s, a collection of 14 gold Roman coins, known as the Chapipi treasure, was also found in the same woodlands. The researchers believe that local people may have buried their coins to keep them safe during a period of intense political instability in the region. The most recent coin in the newly-discovered Grado collection dates to A.D. 430, which was after the Suebi—a group of Germanic people originally from modern-day Germany and the Czech Republic—pushed the Romans out of Spain in A.D. 409, according to El Pais.
The researchers suspect that the newly-discovered coins are part of a vaster treasure and will return to the cave for further exploration to look for more coins and evidence that the cave may also have been the home of displaced Roman people. “We want to know if it was a one-off hiding place, or if there was a group of humans living there,” lead researcher Alfonso Fanjul Peraza told El Pais.
【1】Where did the researchers find the first few coins in 2021?
A．Near a Spanish cave.
B．On a Spanish playground.
C．At the entrance to a woodland.
D．In a badger’s den.
【2】What do the researchers think of the discovery in 2021?
A．It’s dangerous.
B．It’s timely.
C．It’s meaningless.
D．It’s unusual.
【3】What does the underlined word “them” refer to in Paragraph 4?
A．The Romans.
B．The coins.
C．The woodlands.
D．The researchers.
【4】What can we infer from the last paragraph?
A．More information may be revealed by the coins.
B．The ancient Roman people had a unique lifestyle.
C．The researchers doubt the former guess of the coins.
D．The researchers will return the coins to the Roman people.
24、Since 2016, the U=U (Undetectable=Untransmittable) campaign, started by Bruce Richman, who was diagnosed with HIV in 2003, has teamed up with 570 other organizations in 71 countries to share the message: “In most of these countries people have been taught to fear HIV and people with HIV. Now we’re turning a corner.”
The impact of this and other prevention strategies and campaigns has begun to reduce new infection rates. As is reported, the number of new diagnoses in San Francisco has dropped by more than 50 per cent since 2006, in large part because of this “treatment as prevention” approach, also known as TasP.
But more work is needed, for example, on a vaccine. For some other viruses, vaccines work by mimicking(模仿)the biochemistry of people who seem to be naturally protected from infection. “For HIV, we don’t have a good naturally protective correlate to work with,” says Lundgren, an official in UNAIDS. Another difficulty is the lack of a good animal model for human HIV infections. Potential vaccines that show promise in monkeys infected with the similar simian immunodeficiency virus have not been successful in human clinical trials.
There are also hopes for an HIV cure, but this has been harder to come by than expected. The main problem with trying to cure HIV is that there is a hidden reservoir of the virus in the body. That is why the leading strategy in the hunt for a cure is the “kick and kill” approach. T his aims to kick HIV out of cells that act as a reservoir and then kill the virus.
While focusing on such scientific problems to make a cure a possibility in future, researchers at pharmaceutical company Gilead are also making progress when it comes to the potential for longer-acting treatments. At the moment, antiretroviral(抗逆$专录病毒的）drugs must be taken on a daily basis and this can prove difficult for some.
Winston Tse，a senior scientist at Gilead, is working on a treatment that looks to be particularly effective and could take the form of a long-acting injection. He and his colleagues have set their sights on a protein that surrounds and protects the HIV RNA genome which is essential to viral(病毒的）life including its ability to infect new cells. The team is developing compounds that interfere with this protein and so prevent the virus to reproduce.
It is this focus on prevention and treatment that makes the UNAIDS goal potentially achievable—removing AIDS as a public health risk by 2030. “I would love a cure, but I’m investing my time into the strategy of testing, treating and prevention, because I think that’s the way to end this disease,” says Richman.

【3】What do we know about the “kick and kill” approach?
A. It is less effective than expected. B. It destroys the reservoir of the virus.
C. It kills the virus out of the cells. D. It belongs to the antiretroviral drugs.
【4】What can we infer from the UNAIDS goal??
A. AIDS will become a public health risk by 2030.
B. A cure for AIDS is more important than prevention.
C. Doing more trials is the solution to stopping AIDS.
D. Researchers are confident in preventing AIDS in future.
