2023 年高考英语复习——高三英语阅读理解专项练习（七）
A
A new test for COVID-19 is coming to store shelves throughout the U.S. This is the first test for the disease that you can do at home. It does not need a prescription, or doctor’s approval, to use.
Currently, the U.S. is testing nearly 2 million people daily, and most health experts agree the country needs to be testing many more people than that. Most tests still require a nasal swab (鼻拭子) performed by a health professional, followed by processing at a laboratory. That typically means you have to wait days for the test results.
For months, health experts have stressed the need for fast, widespread home testing, which allows people to screen themselves and avoid contact with others if they have an infection. With this new home test, people can “swab their nose, run the test and find out their results in as little as 20 minutes,” said FDA commissioner Stephen Hahn.
The test kit includes a small tool to help you to take nasal swab, or sample from inside your nose. Once you swab your nostril (鼻孔) you place the swab onto a small cartridge. This cartridge analyzes the sample and sends the results to an app on your smartphone. The app displays the results and then helps you interpret them. Users can also connect with a health professional through the app.
Ellume’s test works differently than other tests. Most tests look for the genetic material of the virus. This is the material that hakes up its genes, which influence how the virus looks and acts. However, Ellume’s test looks for proteins that the virus sheds (散发). These viral proteins are large molecules that can trigger a response from your immune system, which is the collection of cells and their responses that help the body fight off infections.
Like other COVID-19 tests that look for proteins, Ellume’s test still has a shall chance of errors. FDA officials say that people who get a negative result but still have coronavirus symptoms should follow up with a doctor.
Although the price of the test could prevent some people from using it, Dr. Michael Mina, a professor at Harvard University in Cambridge, Massachusetts, called the new test “a great addition” to existing options.

Plenty of films are somewhat incomprehensible, but a movie is in a language that only about 20 people in the world can speak fluently.
A feature film titled SGaneaay K’uuna, translated as Edge of the Knife, is in the Haida language, the ancestral tongue of the Haida people of British Columbia, Canada It is unrelated to any other language, and actors had to leam it to understand their lines.
The film is playing an important role in preserving the language, its director Gwai Edenshaw said.
“I know that, if our language is this far gone, statistically it’s supposed to be over. But that’s not something that we’re willing to accept.”
The Haida are an indigenous(土著的)community whose traditional territory is Haida Gwaii Edenshaw said most of the fluent Haida speakers were in his Haida Gwaii homeland. The community generally lives off the sea and makes dugout canoes and houses from local red cedars. Their numbers were ravaged by smallpox and other diseases in the 19h century. A former population of tens of thousands has declined to a few thousand today.
The few Haida speakers are extremely concerned about the language’s future and were very enthusiastic about the film. More than 70 local people worked on the production, with Haida speakers taking incidental roles, weavers creating the costumes and other craftspeople making props.
The film, set on Haida Gwali in the 19th century, is based on an old Haida myth about a man who survives an accident at sea, only to become so weakened that he is taken over by supernatural beings.
It is part of a wider push to preserve the Haida language, including a new dictionary and recordings of local voices.
Mark Turin, associate professor at the University of British Columbia, said that Haida is among languages that have been ”pushed almost to the edge“ and that, while numerous indigenous communities worldwide are trying to revive(复活)their language, the Haida people have taken an unusual approach. ”This film has done something that I don’t think I’ve ever seen before, using a feature movie as a process of language revitalization. It’s a hugely creative and powerful commitment for the community to have made,“ he said.
5. What do we know about the Haida language?
A. It is forever gone. B. It is easy to learn. C. It is well preserved. D. It is highly endangered.
6. What does the underlined word “ravaged” in Paragraph 4 probably mean?
A. Greatly reduced. B. Slightly increased. C. Stabilized. D. Determined.
7. What do we know about SGaateay K’uuna?
A. It is based on a true story. B. Locals contribute to its production.
C. Most Haida speakers lack interest in it. D. It helps promote the Haida publications.
8. What does Mark Turin think of using a film to revive a language?
A. It is innovative. B. It is outdated. C. It is unacceptable. D. It is debatable.

On paper, hydrogen looks like a dream fuel. In practice, things are trickier. Storing meaningful quantities of hydrogen gas requires compressing (压缩) it several hundred times. Transforming it into liquid state is another option, but one that requires cooling the stuff to -253℃. Either process requires rugged tanks. Over time, hydrogen gas can pass slowly into metals, weakening them and potentially causing cracks. Tanks must be built from special materials designed to resist this breakdown.
Researchers at the Fraunhofer Institute led by Marcus Vogt, think that supplying hydrogen as goop (糊状) offers a way around some of its limitations. They have been experimenting with a chemical compound that can be pumped into a container and then persuaded to give off its hydrogen on demand.
Their invention which they nickname “powerpaste”, looks like toothpaste. Its main ingredient is magnesium hydride, a compound that when introduced to water, reacts with it to form hydrogen and magnesium hydroxide. The escaped hydrogen can then be redirected into a fuel cell, where it reacts with oxygen from the air to generate electric power. The magnesium hydroxide waste is emptied from the reactor automatically.
Dr Vogt’s scheme offers several advantages over batteries, petrol and more conventional ways of handling hydrogen. One is the storage of energy than either batteries or petrol can manage. A second is ease of refilling, which is simply a matter of swapping an empty container of paste for a full one, and topping up the water, which is stored in a separate tank. A third advantage is that, unlike a battery, the paste does not gradually lose its stored energy if it is left on the shelf. Moreover, the paste itself is harmless, as are the reaction’s by-products.
But there are still more to work through. Magnesium hydride reacts only slowly with water. To overcome this, Dr Vogt and his team have found a chemical additive that greatly accelerates the reaction. They have also found a way to ensure that the reaction can be controlled precisely enough to supply only as much hydrogen as is needed at any given moment.
9. Which of the following best explains “rugged” underlined in paragraph 1?
A. Creative. B. Fragile. C. Tough. D. Enormous.
10. What can we know about the invention according to paragraph 3?
A. Magnesium hydride mixed with water releases hydrogen.
B. Several chemical reactions occur in the same tank.
C. Water and electricity are necessary in the process.
D. The remaining waste needs removing with extra help.
11. How is paragraph 4 mainly developed?
A. By providing examples. B. By drawing comparisons.
C. By quoting sayings. D. By explaining a concept.
12. What can be a suitable title for the text?
A. Dream Fuel: Hydrogen Gas B. New Clean Energy
C. Advantages of Hydrogen Goop D. “Toothpaste” in Your Tank

In September 2017, Hurricane Maria hit Puerto Rico, killing 3,000 people and affecting normal life for months. The storm first arrived on a small island off the main island’s eastern coast called Cayo Santiago, which is home to some 1,500 rhesus macaques (恒河猴). To everyone’s surprise, nearly all the monkeys survived the storm. The monkeys reacted by changing their social order, it turned out.
After the storm, the observers noticed that the monkeys seemed to become more tolerant. Were they really more tolerant of one another? To find out, the new paper compares two behaviors during the three years before the storm and for one year afterward.
The team assumed that the monkeys would strengthen existing bonds, but that is not what happened. “We saw active building of relationships with individuals that they didn’t really interact with before.” says Michael Platt.
That probably came largely from the need for shade, which had become a limited resource after the hurricane. “What types of social relationships are going to be most helpful if what you need is relief from the Caribbean sun?” says behavioral ecologist Lauren Brent. “The best solution might be to expand areas, make some new connections, and make sure you’ve always got some shade available. Imagine walking into a crowded bar and trying to find a seat at a table: the more people you know, the more likely you are to be able to sit down.”
