21、 Two years ago, aerospace manufacturer SpaceX shocked the world by landing its reusable booster (助推器) engine — the biggest and most costly part of the rocket used to power spacecraft into low orbit — on an autonomous drone ship in the Atlantic Ocean. Now, California-based startup Rocket Lab, has come up with an even more courageous idea: using parachutes and helicopters to capture the returning booster, or first stage as it is often called, in the air!
Rocket Lab’s decision to avoid the propulsive or vertical (垂直的) landing used by SpaceX comes from its business model to keep its Electron rockets small and cost-effective. Standing just 57 feet tall, they are designed to deliver smaller payloads (有效载重) of about 500 pounds for only $5 million a launch. In contrast, the SpaceX Falcon 9 rocket measuring 229 feet tall can lift up to 50,000 pounds, costs about $62 million a mission. “We’re not in the business of building medium-sized launch vehicles but small ones for customers to get on orbit frequently.” said Rocket Lab CEO Peter Beck.
Similar to other rockets, the Electron divides into two once it reaches outer space. While the top part, carrying the load, continues on to its final destination, the booster engine falls back to Earth The company intends to fix a ballute — a parachute-like braking device — to quickly slow down the booster's supersonic speed (超声速) upon its return into the atmosphere. Once it slows down to a reasonable pace, a helicopter will grab the rocket from midair and put it onto an awaiting ship to transport to the company's headquarters. Beck said: “The grand goal here is that if we can capture the vehicle in wonderful condition, in theory, we should be able to put it back on the pad, charge the batteries up, and go again.”
The idea, still in the concept stage, will become one step closer to becoming a reality during Electron’s next launch, scheduled for sometime in 3 years, “Engineers will carefully monitor the first stage as it returns, testing its ability to guide its landing with the best way to slow down its speed,” said Beck.
【1】We can infer from the first two paragraphs that ___________.
A.with a height of 229 feet, the Space X Falcon 9 rocket can deliver a load of 50,000 tons
B.small launch vehicles are designed by Rocket Lab to make its boosters economical
C.Space X once successfully captured its rocket before it landed on a ship in the Atlantic Ocean
D.an autonomous drone ship is used by Rocket Lab to transport the first stage
【2】What distinguishes the Electron from other rockets?
A.It will be equipped with a ballute to reduce its landing speed.
B.Its booster engine falls back to the earth with the load.
C.It divides into two the instant it enters outer space.
D.It is loaded on a helicopter heading for the company’s headquarters.
【3】What will Rocket Lab’s following research focus on?
A.How to capture the booster engine without damaging its function.
B.When to slow down the first stage as it returns.
C.How to cut the cost of each launch mission by calculation.
D.How to make its rockets smaller and more reusable.
【4】In which column can you find this article in a piece of newspaper?

22、 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

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.
23、A well-dressed man came to a famous jewelry shop. He explained that he wished to buy a pearl for his wife’s birthday. The price didn’t matter. Since business had been very good for him that year. After examining a nice black one that cost $5000, he paid for the pearl in cash, shook hands with the jeweler, and left.
A few days later the man returned and said that his wife liked the pearl so much that she wanted another one just like it. It had to be exactly the same size and quality, because she wanted a pair of earrings made, “Can you give me any advice on how to get such a pearl? ” said the man. The jeweler regretfully replied, “I would say it’s exactly impossible to find one exactly like that pearl.”
The rich man insisted that the jeweler advertise in the newspapers, offering $ 25,000 for the matching pearl. Many people answered the advertisement but nobody had a pearl that was just right.
Just when the jeweler had given up hope, a little old lady came into his store. To his great surprise, she pulled the perfect pearl from her purse. “I don’t like to part with it,” she said sadly, “I got it from my mother, and my mother from hers. But I really need the money. ”
The jeweler was quick to pay her before she changed her mind. Then he called the rich man’s hotel to tell him the good news. The man, however, was nowhere to be found.

24、In anticipation (预料) of an extraordinary visit, the streets and buildings of Havana, Cuba, were cleaned and painted by dozens of workers. What was the occasion?
For the first time in nearly 90 years, a sitting United States president was coming to Cuba, an island nation 90 miles south of Florida. On Sunday, President Barack Obama, joined by his family, stepped off Air Force One and onto a rainy runway, where Cuban dignitaries (高官) eagerly awaited him. “It’s wonderful to be here, ” the president said. The last time a U.S. president came to Cuba was in 1928. It was President Calvin Coolidge, and he arrived on a battleship. Obama will be in Cuba through Tuesday. He is set to meet with Cuba’s president, Raul Castro, attend a state dinner and even take in a baseball game.
The U.S. cut all ties with Cuba after Fidel Castro’s communist government took control of the island in 1959. In the years that followed, both countries’ opposing political views furthered the separation. Plans for social and economic change began after President Fidel Castro transferred power to his brother, Raul in 2008. Raul Castro then set a plan in motion to revive the country’s economy.
Since then, Cuba has been taking small, yet lasting steps toward change by removing a number of restrictions that had been set on its citizens, such as access to the Internet, the use of cellphones, and by allowing people to work at jobs not controlled by the government. Cuba, however, still has tough limits on media, public assembly and political opposition.
Obama hopes to share his vision for Cuba’s future during a speech he will deliver. Before the trip, Senior Advisor Ben Rhodes said the president hoped to use this visit as a way to “continue to create openings for great engagement between the American and Cuban people.”
【1】What is stressed in the second paragraph?

A. Cuba is central to conflict.
B. Cuba takes on media freedoms.
C. Cuba is working towards progress.
D. Cuba makes sure the right to healthcare.
【4】According to Ben Rhodes, which is the purpose of Barack Obama’s visit to Cuba?[
