21、However exciting space exploration sounds, there’s a necessary and important point about it that needs to be considered: food supplies. Right now, astronauts typically rely on dry food in airtight bags and cans, since there are strict weight limits on items taken into space. Foods that we take for granted, such as fresh fruit and vegetables, are out of the question for space explorers.
For those who’ve made an effort to try to grow food during space flights, they’ve faced many difficulties, including the absence of gravity, and a lack of soil, air and humidity (湿度). However, growing food to add and minimise (最小化) the food that must be carried to space will be increasingly important on long-duration flights into space. Great efforts have been made to explore the idea of space farming. Recently, a team led by Federico Maggi at the University of Sydney in Australia have worked out how plants can absorb nutrients from human urine (尿) , as was reported by New Scientist on March 27.
After over 20 years of experiments, the results suggested that human urine could supply three to four out of the six nutrients that plants need. The researchers also found out that urine-fertilised plants produce no harmful by-products, such as carbon dioxide or ammonia.
According to New Scientist, human urine is 95 percent water, with the other 5 percent made from nutrients which are harmful to the human body but not to plants. The advantage of this urine fueled life support system is obvious: By recycling liquid waste and producing food, an efficient cycle will be created.
And most importantly, said New Scientist, the duration of space flights will be greatly extended to “20 years of flight”, meaning we may be soon sending astronauts on flights to Mars, or even beyond.
【1】What does the underlined part “out of the question” in the first paragraph probably mean?
A．Uncertain.
B．Doubtless.
C．Impossible.
D．Unnecessary.
【2】What can we learn from the research by the University of Sydney?
A．Human urine is harmless to plants.
B．Human urine provides six necessary nutrients for plants.
C．Urine fertiliser is safer and more productive than chemical fertiliser.
D．Urine-fertilised plants only release a small amount of carbon dioxide.
【3】What is the biggest advantage of using human urine for space farming, according to New Scientist?
A．It does little harm to the environment in space.
B．It will greatly reduce the cost of farming in space.
C．Urine-fertilised plants are healthier and taste better.
D．It could create conditions for long-term space flights.
【4】What’s the text mainly about?
A．The significance of space farming.
B．A possible new way to grow food in space.
C．How to use human urine to produce food in space.
D．Problems faced by astronauts on long-term space flights.
22、 Ed Jackson："I want to be the first quadriplegic（四肢瘫痪者）to climb Everest，"
Former Wasps player was told he would never walk again after an accident in 2017.
"It was a lovely day like this and we had a barbecue." Ed Jackson says as he remembers the accident which broke his neck，ended his rugby career and left him paralyzed（瘫痪）with a medical prediction that he would never walk again. "I walked to the edge of a feature pool with a waterfall at one end. I couldn't tell which was the deep end so I dived in，fell straight to the bottom，and hit the top of my head. When I tried to stand up I couldn't. Luckily my dad was in the pool. He's a retired doctor and he knew it was a spinal cord（脊柱）issue."
Jackson survived surgery but was told that his paralysis was almost certainly permanent. "After five days of trying to move my toes with nothing happening，I thought there's a good chance they're right."
"Every night on my own，I imagined what it would be like for my wife to look after me for the rest of my life. If this was going to continue all my life，I would never have forgiven myself." In the dark，his mind was at war with itself. "That fear of the unknown is terrifying. Every day I would stare at my toe and try to move it."
On day six his toe twitched（抽动）！The next few months became a series of his exciting moments. Jackson kept chasing those wins.
Once Jackson could walk he decided to climb Snowdon to coincide with the first anniversary of the accident. On 1 April 2018，with a heavy brace on his leg，Jackson reached the summit of Snowdon.
Climbing is exhausting and dangerous for a quadriplegic but，with his face lit by sunshine，Jackson uncovers a previously secret dream. "I want to be the first quadriplegic to climb Everest. I would love that to be where the story of my recovery ends. And then I just want to go on laughing and living.

A.An Accident to Change a Man B.A Quadriplegic to Climb Everest
C.A Secret Dream to Success D.A Man Crazy About Climbing
23、Nothing could stop Dad. After he was put on disability for a bad back, he bought a small farm in the country, just enough to grow food for the family. He planted vegetables, fruit trees and even kept bees for honey.
And every week he cleaned Old Man McColgin’s chicken house in exchange for manure. The smell really burned the inside of your nose. When we complained about the terrible smell, Dad said the stronger the manure, the healthier the crops, and he was right. For example, just one of his cantaloupes filled the entire house with its sweet smell, and the taste was even sweeter.
As the vegetables started coming in, Dad threw himself into cooking. One day, armed with a basket of vegetables, he announced he was going to make stew. Dad pulled out a pressure cooker and filled it up with cabbages, eggplants, potatoes, corns, onions and carrots. For about half an hour, the pressure built and the vegetables cooked. Finally, Dad turned off the stove, the pot began to cool and the pressure relief valve sprayed out a cloud of steam. If we thought Dad's pile of chicken manure was bad, this was 10 times worse. When Dad took off the lid, the smell nearly knocked us out.
Dad carried the pot out and we opened doors and windows to air out the house. Just how bad was it? The neighbors came out of their houses to see if we had a gas leak!
Determined, Dad filled our plates with steaming stew and passed them around it didn't look that bad, and after the first wave had shut down my ability to smell, it didn't offend the nose so much, edible, and we drank up every last drop of soup!
【1】What can we infer about Dad’s stew?
A．It is popular among the neighbors.
B．It contains honey and vegetables.
C．It looks very wonderful.
D．It tastes quite delicious.
【2】What does the underlined word “offend” in the last paragraph mean?
A．To attract. B．To upset.
C．To air. D．To shut.
【3】What can we learn about Dad from the text?
A．He is an experienced cook.
B．He is a troublesome father.
C．He has a positive attitude to life.
D．He suffers a lot from his disability.
24、 Despite the successful creation of young by cloning various species, researchers still have limited understanding of the technique. Although the overall efficiency and safety of cloning in animals has significantly increased over the past fifteen years, it is not yet a safe process. For example, the rate of dead births and developmental abnormalities remains high. Another source of concern is the risk of premature ageing because of shortened telomeres（端粒酶）. Telomeres get shorter as an animal gets older. When the telomeres of a cell get so short that they disappear, the cell dies. The concern is that cloned animals may get the shortened telomeres, with possibly premature aging and a shortened lifespan as a result.
For many, the fact that cloning is unsafe provides a good reason not to pursue it. It has been argued that it would simply be wrong to put such significant health risks on humans. The strongest version of this argument states that it would be wrong now to produce a child by cloning because it would be a case of illegal birth. Against this, it has been argued that even if cloning is unsafe, it may still be permissible if there are no safer means to bring that very same child into existence.
With the actual rate of advancement in cloning, one cannot deny a future in which the safety and efficiency of cloning will be equal or superior to that of test-tube baby. A remaining question is, then, whether those who condemn（谴责）cloning because of its experimental nature should continue to condemn it morally and legally. Some authors have reasoned that if, in the future, cloning becomes safer than sexual reproduction, we should even make it our reproductive method of choice.
【1】What's the main idea of paragraph 1?
A．All species are able to be cloned technically.
B．The efficiency and safety of cloning is increasing.
C．Various risks still exist in the process of cloning.
D．There's still a lot to learn about cloning technology.
【2】What can we know about telomeres?
A．They differ from species to species.
B．The longer they are, the older the cell.
C．They tend to get thinner when aging.
D．They don't exist in a dead cell.
【3】Why did the opponents condemn human cloning?
A．It would break the existing laws in nature.
B．It would bring great health risks on humans.
C．It has a large gap to be filled up technically.
D．It is against the will of the majority of people.
【4】Which word best describes the author's attitude to human cloning?
A．Positive.
B．Skeptical.
C．Ambiguous.
D．Worried.

26、阅读下面材料，根据其内容和所给段落开头语续写两段，使之构成一篇完整的短文。
It is hard not to desire victory in all your efforts when the world seems so competitive and especially if you’re a boy growing up with those values. A boy grew up in a similar environment where winning was all that was valued and he longed to succeed. The boy was good at running, so he called everyone in the nearby villages for a race. A large group of people came to see this exciting event!
The boy had been training hard for this race. He ran among the strongest boys from around the villages and it looked like heat on a finish line, but the young boy came out victorious! The crowd went wild with delight as they cheerfully waved banners(横幅) praising him. The boy loved the attention. It made him feel happy.
There were several types of races, sprint, long distances, relays etc. The boy was unbeatable in all the races he competed in. The crowd loved him even more after each victory; they clapped with excitement. The boy felt very proud of his accomplishments.
But among the crowd was a wise older man who did not seem as impressed with the boy’s victory as the rest. Just as the boy thought all the races for the day were over. The old man shouted from the crowd, “there is one more race left—the most important one.” The boy was surprised by the additional race, but he was confident he could win any race.
The old man brought two new competitors for the boy, a blind man and a weak old lady. “What type of race is this? I can easily win them.” the boy exclaimed. “The most important one,” said the old man. So, the boy ran the race as he knew he would win this time too. When the boy crossed the finish line, the blind man was still at the start and the old lady had just started to move. The boy raised his hands after his victory, waiting for the familiar cheering.
