21、 On a recent spring morning. Susan Alexander, a retired government intelligence analyst, left her Maryland home, climbed into her Volkswagen Passat and drove about three miles to pick up two strangers. She battled rush-hour traffic on the Capital Beltway and George Washington Memorial Parkway before dropping them off at Reagan National Airport. She didn't earn a cent for her trouble, and that was the point.
Alexander is a member of the Silver Spring Time Bank-one of more than 100 such exchanges around the world trying to build community by exchanging time credits for services instead of dollars and cents. “I have time,” she said. “I like giving the gift of time to other people. “
In Alexander's case, passengers Mary and Al Liepold were grateful for the ride, but it wasn't charity. Mary,a retired writer and editor for nonprofit organizations, used time credits she banked for editing work and baking. Senior citizens who don't drive, the Liepolds cashed in their credits to catch a flight to Montreal for a five-day vacation.
Without money changing hands or shifting between virtual accounts, the airport drop-off was more like a coffee party than a taxi ride. Driver and passengers chatted about projects they've completed for the time bank, and no one raised an eyebrow when Mary said she likes “to avoid the conventional economy. “
“The beauty of this is that you make friends,” Mary Liepold said. “You don't just get services.”
The Silver Spring Time Bank formed in 2015 and has about 300 members, said co-founder Mary Murphy. Last year, she said, l,000 hours were exchanged for basic home repairs, dog walking, cooking and tailoring, among other services, without the exchange of money. “ You get to save that money that you would have spent,” she said. “You get to meet somebody else in your community and get to know that person. That's a bonus that's part of an exchange. “
A deal performed partly to make friends would seem to go against classical economics and one of Benjamin Franklin's most memorable sayings:”Time is money. “ To those at the forefront of modem time-banking, that is the appeal.
【1】What's the main purpose of the Silver Spring Time Bank?
A. To better serve the local economy.
B. To help people get to know more friends.
C. To provide the elderly with timely financial help.
D. To build community by exchanging time credits for services.
【2】How did the Liepolds pay for their ride?
A. In cash. B. By credit card.
C. By cheque. D. With time credits.
【3】What does the underlined word “that” in the last paragraph refer to?
A. Making friends. B. Classical economics.
C. Modem time-banking. D. Franklin's famous saying.
【4】What is the suitable title for the text?
A. Time is money B. The more friends, the better
C. Giving the gift of time D. Swapping time credits for services
22、THE idea came to Ralph Liedert while he was sweating in the Californian sunshine, having been standing with his daughter for over an hour in a queue for a ride at Disneyland. What, he thought, if his T-shirt had a cooling system he could turn on, at the tap of a smart phone app, when he needed it. Luckily, Mr Liedert does have the means to make the dream reality, for he works at the VTT Technical Research Centre of Finland, as one of a team there studying the rapidly growing field of microfluidics (微流控技术).
Cooling vests already exist (used by racing drivers, motorcyclists and people who work in hot conditions). But the tubes through which the cooling water is being pumped, and the vests’ need to be connected to outside units that cool this water, make them huge and clumsy. Mr Liedert thought VTT’s microfluidics department could do things better.
As its name suggests, microfluidics is the art of building devices that handle tiny amounts of liquid. Inkjet-printer cartridges (喷墨打印机墨盒) are a familiar example. Less familiar, but also important, are “labs-on-a-chip” (芯片实验室). These are tiny analytical devices that transport fluids such as blood through channels half a millimetre or less in diameter (直径), in order to carry them into what holds analytical reagents (试剂). Sensors, then detect the resulting reactions and provide an instant analysis of a sample (样本). Designing labs-on-a-chip is the VTT microfluidics department’s day job. One of its chips, for example, can tell whether water is affected by the bacteria that cause Legionnaires’ disease.
The department’s biggest contribution to the field, though, is to have developed a way of printing microfluidic channels onto large rolls of thin, flexible plastic. It works by passing the plastic between two heated rollers, one of which contains raised outlines of the required channels. As the rollers squeeze the plastic they create a pattern of channels into one surface. A second plastic film is then melted over the top as a cover. This process might, thought Mr Liedert, be suitable for printing a microfluidic cloth that was thin enough and pleasant enough to wear as a cooling vest.
The group’s first model showed that such a material could indeed be made and used to circulate cooled water. They are also looking at ways the water being circulated through the microchannels might be cooled. They have identified two. One uses a small heat-exchanger, the details of which they are keeping secret at this stage. The other employs evaporation (蒸发). It thus works in the same way that heat from circulating blood is removed by the evaporation of sweat.
Whichever cooling system is applied, the electronics needed to power and control it would be shrunk into a small package contained on the back of the vest. This could be operated by hand or, as Mr Liedert originally envisaged in his Californian queue, by a wireless link to a smart phone. Moreover, what can cool down can also, if run in an opposite way, warm up. In Finland, where winter temperatures fall as far as -50°C, that might be the technology’s killer app.
【1】Microfluidics has been used in ______.
A. racing cars B. printing industry
C. testing material D. clothing industry
【2】We can learn from the passage that ______.
A. VTT is a company which mainly works on the research into microfluidics
B. the new cooling vest of VTT will be smaller and work more effectively
C. the technology of microfluidics may have a positive effect on medical science
D. heat-exchanger as well as the way of evaporation will be used to cool the wearer
【3】______ plays the key role in making the new cooling vest.
A. The special cloth B. The cooling system
C. The tiny liquid D. The wireless link
【4】The underlined word “envisaged” most likely means _____ .
A. imagined B. discovered C. viewed D. planned
23、One of the classic science-fiction treatments of the end of civilization was The Death of Grass, by John Christopher, in which a mysterious sickness struck down all the grasses on which most of the world's agriculture is based, from rice to wheat. Tn the end, politics among the survivors of disease, war and famine were reduced to bitter fratricidal struggle over a defensible potato patch. Like most of the so-called 'comfortable disaster" novels, this could be criticized for optimism. Depressing as a future of famine and the war of all against all might seem, the consequences were largely limited to humans.
However, the threatened extinction of insect populations around the world raises the prospect of a much less general disaster, which would involve plants, birds, fish, small mammals, and everything else depending on insects. That's just the start. Other species, and we ourselves, depend on the animals and plants that need insects. When they go, we go. This is not just a greater disaster. It's a much more reasonable one. The most recent study has concluded that insect biomass is decreasing around the world at a rate of 2.5% a year. At that rate, half the insects in the world will be gone in 50 years' time, and all of them in a century — though no one will be keeping track of centuries then.
The chief driver of this disaster is unchecked human greed. I spite our individual and even collective cleverness, we behave as a species with as little foresight as a colony of nematode worms that will consume everything that it can reach until all is gone and it dies off naturally. The challenge of behaving more intelligently than creatures that have no brain at all will not be easy. But unlike the nematodes, we know what to do. The UN convention on biodiversity was signed in 1992, alongside the convention on climate change. Giving it the strength to hold back our appetites is now urgent. Biodiversity is not an optional extra. It is the web that holds all life, including human life.
The two main expressions of greed that speed this apocalypse are global warming and industrial agriculture. It appears that most of the damage is being done in the developed world by farming practices. The use of giant fields, lack of shelter for insects of any sort at all, whether they are harmful to human interests or not, and where the plants are drenched in long-lasting pesticides, is fatal for uncounted billions of insects. The effects of this kind of forming reach beyond the fields immediately affected, too. There has been a huge loss of aquatic insect species from the rivers into which the products of industrial agriculture arc flushed by rain. Even in German nature reserves, which arc by definition protected from the use of pesticides, there have been sleep falls in insect populations because so many of the most widely used ones are persistent and prevent breeding.
【1】Which of the following statements about The Death of Grass is true?
A.It holds an optimistic attitude towards famine in the future.
B.It understates the severity of the disaster facing the world.
C.It gives a vivid account of the most serious famine in history.
D.It demonstrates how evil human nature turns out to be.
【2】In paragraph 2, the writer mentions the most recent study in order to________.
A.prove that the prediction about the great disaster makes sense
B.show how soon the insects worldwide will go extinct
C.argue for the necessity to protect insect populations
D.suggest a possible approach to increasing insect biomass
【3】What can be inferred from the passage?
A.Humans are similar to nematode in that both of them lack foresight.
B.We haven't done enough about maintaining biodiversity.
C.Modem farming is to blame for the threatened extinction of insects.
D.Germany sets a good example by minimizing the use of pesticides.
【4】What will the author probably discuss after the last paragraph?
A.How industrial agriculture brings about apocalypse.
B.What influence pesticides may have on people's lives.
C.Why insect populations in Germany are on the decline.
D.Where unchecked human greed can also by spotted.
24、Images of polar bears struggling to stay on rafts of ice are often used by groups that want to promote conservation and stop the deterioration of natural habitats. However, part of the solution lies with the polar bears themselves.
Polar bears are highly specialized. This means they have adapted to survive in a specific region and eat specific food. Polar bears live above the Arctic Circle and eat fish. Their bodies are different from those of other types of bears. Polar bears feature webbed feet for swimming, thicker fur and more body fat for living and swimming in icy conditions, and light-colored fur to help them blend into their environment. As a result, polar bears do not do well when they are in a non-arctic region. They cannot run as well as other bears, they can become too hot and tired easily, and they have a hard time hunting animals that are not in the snow or ice.
Unfortunately for polar bears, climate change is reducing the size of the areas where they can live. This means the bears will eventually have to leave the arctic regions and travel farther south. However, because they are so specialized, it is unlikely that polar bears will be as strong as they once were.
Other creatures, such as crocodiles, are not nearly as specialized. They live on almost every continent and in a wide variety of climates. In fact, crocodiles are one of the most adaptable animals on the planet and have survived for millions of years. When animals specialize, they often do better than less-specialized species in the same place, but if the climate or other conditions change, the specialized animals are usually the first to die off.
If polar bears are going to survive the next 100 years, they will have to adapt. Many scientists believe that polar bears may eventually cross paths with brown bears and black bears. Whether these animals fight it out or fall in love to create new generations of bears remains to be seen. No matter how it happens, many hope the polar bears will live far into the future-in many different places.
【1】Which of the following is an effect of polar bear specialization?
A.Polar bears are not in danger of dying off.
B.Polar bears fight other bears for food.
C.Polar bears adapt to new habitats.
D.Polar bears hunt well in arctic areas.
【2】The example of crocodiles is used to show________.
A.the cause of climate change
B.the importance of adaptability
C.the history of biological evolution
D.the changes of natural environment
【3】Which detail about polar bears best explains why they are comfortable in icy water?
A.The color of their fur.
B.Their tendency to easily overheat.
C.Their more body fat and thicker fur.
D.Their ability to travel on ice rafts.
【4】If they cannot adapt to climate change in the Arctic, polar bears will________.
A.no longer exist
B.find a colder place to live in
C.live in the south of the Arctic Circle
D.act more like brown and black bears

26、阅读下面短文,根据所给情节进行续写,使之构成一个完整的故事。
I live with my husband in San Luis Obispo, California, about three miles from the beach. Every few years, the humpback whales come into the bay for a few days while they’re migrating. November 2020 was one of those times, so we took out our yellow double kayak(皮艇)to watch the wildlife. We paddled out the length of the pier(码头)and saw seals, dolphins, and about 20 whales feeding on silverfish. We were in awe watching these graceful giants—each one about 50 feet long—breach and spray through their blowholes. We laughed when they turned their side fins so that it looked as if they were waving at us.
At the time, my friend Liz was staying with us. The next day, I asked her if she wanted to go out on the water to see them.
“No way,” said Liz, now 65. She was not an experienced kayaker and was terrified that the kayak would overturn while we were surrounded by hungry whales. “There’s nothing to worry about,” I assured her. “The craft is stable, and we can turn back anytime. I’ve learned somewhere that whales have enormous mouths but tiny throats. Anything they can`t swallow they spit right out.” After some cajoling(劝诱), she finally agreed to join me. I didn’t want her to miss this magnificent experience and regret it later.
Liz and I got out on the water at 8:30 the following morning. There were already about 15 other kayakers and paddleboarders in the bay. It was warm for November, so we wore T-shirts and leggings. After a half-hour, we had our first whale sighting just past the pier: two humpbacks swimming toward us. How amazing to be that close to a creature that size, I thought as the whales dipped under the waterline.
When whales go down after breaching, they leave what looks like an oil slick on the water. I figured if we paddled toward that spot, we’d be safe from the whales, since they’d just left. We followed them at a distance—or what I thought was a distance. I later found out that it’s recommended to keep 300 feet away. We were more like 60 feet away.
