21、 The Intergovernmental Panel on Climate Change released a report stating that the world is quickly running out of time to keep global warming below 1.5 degrees Celsius. To get there, the world would have to cut current emissions by 45 percent by 2030.That sounds absurdly unlikely.
But before we give in to hopelessness，we should remember that the technology to deal with climate change is going along at high speed. The largest source of U. S. carbon emissions is transportation，and a Green New Deal for motor vehicles would be quite straightforward. The reason is simple：with some government subsidies (补贴), electric cars and buses are now cost-competitive with fossil-fuel vehicles. Electric buses have made the greatest speed into the market, because they are a logical choice for electrification. By the end of 2018, electric vehicles were replacing about 280,000 barrels of oil demand per day — about 84 percent of which was mainly consumed by buses.
The electric car market is also reaching maturity, with appealing designs, longer range, and a quickly-expanding rapid charging network in many countries. It’s worth emphasizing that most of the infrastructure (基础设施) necessary to recharge electric vehicles already exists. People often tend to think that we need to replace every gas station, but actually all homes and businesses already have an electrical connection which can be easily improved for fast charging. All that is needed to go fully electric is enough battery capacity and fast charging stations to deal with long trips.
Now America would have to repair its electricity production, freight rail, shipping, and so on to fully decarbonizes (脱碳) the transportation sector, which will be considerably more difficult than simply rooting out fossil fuel vehicles from the market.
But greening America’s vehicle would be straightforward, relatively cheap, and a huge step forward on climate. The politics of climate change are so fearful that being hopeless can seem logical, but the first step to achieving a tough goal is the confident belief that it can be done. And this particular step wouldn’t even be that tough.
【1】How’s the goal of keeping global warming below 1.5 Celsius according to Paragraph 1?
A.Reasonable. B.Safe.
C.Realistic. D.Impossible.
【2】Compared with fossil-fuel vehicles, electric vehicles now ______.
A.are cost-competitive with government subsidies
B.run at a greater speed on the road
C.deal with longer trips
D.look more appealing
【3】What should we do to promote electric cars now?
A.Replace as many as gas stations.
B.Build more infrastructures for recharging.
C.Make businesses have electrical connections.
D.Solve the problem of long trips.
【4】According to the passage, what is the author’s attitude to electric vehicles?
A.Negative. B.Supportive.
C.Uncertain. D.Indifferent.
22、 Our suits have four layers: thermal underwear on the inside, followed by an electrically heated bodysuit, a thick wool coat, and a half-inch-thick layer of rubber outerwear. There're two layers of hoods, waterproof gloves and 35 pounds of weights. There are two batteries for the heated bodysuit, a backup gas container, and finally, my photography equipment. We look like astronauts minus the helmets.
When we finally dive into the freezing water, we're wearing 200 pounds each. The cold quickly numbs the few square inches of exposed skin on our cheeks, and as the dive goes on, it spreads into our suits and gloves, biting even harder. It’ s almost unbearable. Toward the end, as we're pausing on our way up to let the pressure drop, we search for anything to distract us from the pain. When we finally drag ourselves out of the freezing ocean, I lie face down on the ice, my brain dulled, my skin hard and wrinkled, my lips, hands, and feet swollen and unconscious—then, as my body warms and the blood starts to flow (again), the intense pain is at its worst.
What could possibly make this worthwhile? The sight! Only a few species of seals, penguins, and other birds live in East Antarctica, and no land mammals at all. Below, it’s a rich garden. Antarctic marine life has been largely isolated from the rest of the planet for millions of years, ever since the continent separated from the other continents and froze over. Since then the powerful Antarctic Circumpolar Current has surrounded Antarctica from west to east, creating a sharp change in temperature that prevents the spread of marine animals. The long isolation has allowed a surprising diversity of species, unique to the region, to evolve on the seafloor.
The waters under Antarctic ice are like Mount Qomolangma: magical, but extremely unfriendly. Nothing short of full commitment gets you anywhere. The demand is too great. But that's what makes the images you see here so breathtaking, and the experience of having photographed them and of having seen this place so unforgettable.

23、Nicolas Maire is the model of a professional French chef with years of experience. To help perfect the flavors of the innovative foods, Mr. Maire has a new assistant chef in the form of Sam, an artificial intelligence robot.
Along with a team of flavorists, Sam helps blend a huge group of flavors for clients. In humans the sense of taste stems from multiple receptors (感受器) that are ready to make our brains aware of the nature of any possible food we encounter. Sam lacks this sense of taste, but it has been trained on a database of ingredients gathered over 60 years at the company of Firmenich, a business with a perfume industry origin stretching back to 1895. Using a technique called machine learning, it has raced through examples of flavor combinations and has learnt its own definitions, maturing over 18 months into today's AI robot.
Eric Saracchi runs the digital side of Firmenich. “Flavors are more complex than perfumes,” he says, “and Sam had to understand what a strawberry is or how roasted beef hits the tongue, before finding matches between tastes and foodstuffs (食品).”
One big advantage of an AI robot is that it has no cognitive bias (认知偏见). This lack of human prejudices helps Firmenich to get past any unconscious leaning of the flavorists. The objectivity of Sam, lacking influences that can affect even the most professional of flavorists, allows it to work at speed. “It adds value by combining the knowledge of all the other flavorists here,” says Saracchi.
The machine rapidly gives an indication of how a flavor can be created and how much of an ingredient should be included. And Sam can hold the line between Saracchi's team of flavorists and public tastes, refereeing decisions when the flavorists’ view differs from that of a consumer group.
【1】What does Sam do together with many flavorists?
A．It helps activate humans' tastes.
B．It mixes a series of flavors for guests.
C．It creates a database of ingredients.
D．It makes all kinds of foods very creative.
【2】What is Saracchi's attitude towards the AI robot Sam?
A．Negative.
B．Positive.
C．Unknown.
D．Doubtful.
【3】Where can you find the outstanding feature of an AI chef?
A．In paragraph 1.
B．In paragraph 2.
C．In paragraph 3.
D．In paragraph 4.
【4】What is the best title for the text?
A．Nicolas Maire Owns Some AI Assistant Chefs
B．Sam, the First AI Chef in the World
C．Why French Chefs Like AI Assistants
D．Why Chefs Are Turning to AI
24、A worrying rise in social media posts, suggesting that people leave their Halloween pumpkins in the woods to feed wildlife after October 31, has made wildlife experts concerned. Thousands of pumpkins are discarded in woods across Britain. While well-meaning pumpkin carvers might think they are doing the local animals groups a kindness, leaving your leftover jack-o’-lantern in the woodland is actually doing more harm than good.
“A myth seems to have built up that leaving pumpkins in woods helps wildlife, but behind it are many hidden issues.” said Paul Bunton, engagement and communication officer at The Woodland Trust, according to The Telegraph.
One of the main issues is that the leftover of the Halloween pumpkins are often eaten by already struggling hedgehogs(刺猬). In early November, hedgehogs are looking to gain as much weight as possible to survive their winter hibernation. However, eating pumpkin is harmful to their little hedgehog stomachs, leading to diarrhea and dehydration. This means they may struggle to put on weight, and in some cases can even be fatal.
Moreover, leftover Halloween pumpkins can contain candles and plastic decorations which can also be fatal to wildlife if mistakenly eaten. The rotting leftover can also attract less popular wildlife, such as rats, to an area. According to The Woodland Trust, the additional nutrients in the pumpkins can negatively affect the soil balance as well. “Pumpkin flesh can have a really harmful effect on woodland soils,plants, and fungi(真菌),” Bunton pointed out.
So what should you do with your beautifully carved pumpkin creation after October 31? Most experts recommend composting (堆肥) it yourself at home if you can, or asking if a local farm will accept it as a donation. You could even try some scientific experiments to produce more energy from the throw-away wasted. Either way, the hedgehogs will thank vou.
【1】What does the underlined word “discarded” mean in paragraph 1?
A．Processed.
B．Recycled.
C．Deserted.
D．Preserved.
【2】Why do hedgehogs try to eat so many pumpkins in early November?
A．To enjoy the sweet food.
B．To fill their stomachs.
C．To prepare for the winter.
D．To improve their health.
【3】What is paragraph 4 mainly about?
A．The additional nutrients in the leftover pumpkins.
B．The damages of candles and plastic in the pumpkins.
C．The attraction of the rotting leftovers to some wildlife.
D．Further explanation of the effect of leftover pumpkins.
【4】What are people advised to do with the leftover pumpkins after Halloween?.
A．Stop leaving your pumpkins in the woods.
B．Keep your beautiful pumpkin creations at home.
C．Feed the hedgehogs with the leftover pumpkins.
D．Bury the pumpkins leftover deep under the ground.
