阅读理解

    Since December, there have been tens of thousands of the COVID-19 cases both in and out of China, caused by a previously unknown virus: novel coronavirus.

    What are they? Viruses are considered to be non-living organisms(有机物).They can't reproduce(繁殖) on their own. Instead, they invaded the cells of living organisms to reproduce, spread and take over. But the basic question is, where did viruses first come from? Until now, no clear explanation for their origin exists.

    Understanding the origins of viruses means fully understanding the history of their hosts not only humans, but also bacteria, plants and other animals, which is a complicated task. However, there are three main theories to explain the origin of viruses. First, viruses started as independent organisms, then became parasites(寄生者). Second, viruses evolved(进化) from pieces of DNA or RNA that "escaped" from larger organisms. The third one is that viruses co-evolved with their host cells, which means they existed alongside these cells.

    For the time being, these are only theories. The technology and proofs we have today cannot be used to test these theories and discover the most plausible explanation. Continuing studies may provide us with clearer answers. Or future studies may find that the answer is even more mysterious than it now appears.

(1)、What can we learn about viruses from the article?
A、They mainly infect animals and plants. B、They are really small living organisms. C、They are more dangerous than bacteria. D、They can't reproduce unless they find a host cell.
(2)、Which of the following might explain the origin of viruses?
A、They evolved along with their host cells. B、They evolved from the DNA or RNA in animals. C、They evolved from the fossils of large organisms. D、They evolved from parasites to independent organisms.
(3)、The underlined word "plausible" in the last paragraph probably means______.
A、creative B、reasonable C、common D、unbelievable
(4)、What can we conclude from the article?
A、The author is confident about future virus research. B、Viruses will become more like bacteria as they evolve. C、Viruses live longer in human host cells than in animals. D、It may take a long time to understand the origin of viruses.

    “People today prefer living together to putting their signatures on a marriage certificate because they refuse to accept responsibility for the relationship,” said social worker Ken Yip, “and this is what is causing a lot of family problems.” When we sign a paper, for example, a business contract or a bank document, the signature is a seal of consent, an agreement to take the matter seriously. Most governments and many organizations will not process written complaints if they do not bear the writer's signature. The absence of a signature, they explain, tells us that the writer cannot be too serious and therefore does not deserve a reply.

    There are people who wish to remain anonymous(匿名的) for various reasons. Multi-billionaire Mr. King donates generously to charity several times a year. He gives simply because he wants to help but not for the publicity his donations may bring, and he does not want his good deeds to make news. In other cases, people insist on anonymity because they are afraid of the consequences of revealing their identity. Crime witnesses may be willing to assist the police, but most are unwilling to give their names when reporting a crime.

    Name or no name? The answer is very personal and lies in how much we want to get involved. We all have a name. It is a matter of responsibility to use it when we make a statement, a claim or an accusation. We all want to honor our own name, and it is only by stamping our expression of an opinion with our own name that we honor what we say.

    The bus was full of the sounds of laughing and yelling fifth graders. They were on their way to the zoo for a class trip. Mario was excited to see the zoo, but there was one problem. It was ten o'clock in the morning, but his stomach was already grumbling(咕咕叫). He reached down and grabbed his lunch bag. Opening it, he saw that it contained a peanut butter and jelly sandwich, an orange, and two cookies. Mario sighed. He always had peanut butter and jell.

    “Trade you lunches,” he said to the boy seated next to him on the bus.

    “Okay,” said Mark as he handed his brown bag to Mario.

    Mario opened it and was hit with the smell of tuna(金枪鱼). Mario wrinkled his nose and quickly closed the bag. He leaned forward and tapped the shoulder of the girl in front of him.” Swap lunches, Toni?” he asked.

    “Hmm, okay,” said Toni.

    Mario smiled. This was fun. But when he looked into the bag, he frowned. What a disappointment! A ham sandwich, but no cookies! He had to have cookies.

    Mario turned in his seat. “Want to trade lunches?” he asked Juana.

    “Definitely!” said Juana. She grabbed his lunch and tossed hers onto his lap.

    He opened the lunch bag. Pizza! He reached into the bag to grab it. Oh, no! The pizza was hard. He could hit a home run with pizza that hard.

    Mario twisted in his seat. One last try, he told himself. “Hey, Mona! Trade lunches?”

    Three rows behind him, Mona seemed hesitant: Finally, she nodded. She passed her lunch forward, and he passed his back.

    Mario took a deep breath and opened the bag. It was a peanut butter and jelly sandwich, an orange, and two cookies. The sandwich was a little squashed(挤压), and one of the cookies was broken.

    Mario ate it anyway. And it was delicious.

    What happens inside the head of a soccer player who repeatedly heads a soccer ball. That question motivated a study of the brains of experienced players.

    Researchers at the Albert Einstein College of Medicine in New York selected 34 adults, men and women. All of the volunteers had played soccer since childhood and  now competed year﹣round in adult soccer leagues. Each filled out a detailed questionnaire developed especially for this study to determine how many times they had headed a soccer ball in the previous year, as well as whether they had experienced any known concussions in the past.

    Then the players completed computerized tests of their memory and other learning skills and had their brains scanned. using a complex new M.R.I. technique which can find structural changes in the brain that can't be seen during most scans.

    According to the data they presented, the researchers found that the  players who had headed the ball more than about 1, 100 times in the previous 12 months showed significant loss of white matter in parts of their brains involved with memory, attention and the processing of visual information, compared with players who had headed the ball less.

    This pattern of white matter loss is "similar to those seen in traumatic brain injury", like that after a serious concussion, the researchers reported, even though only one of these players was reported to have ever experienced a concussion.

    The players who had headed the ball about 1, 100 times or more in the past year were also generally worse at remembering lists of words read to them, forgetting the words far more often than players who had headed the ball less.

    Edward Latter, five, thought his dog Morse was gone for ever after cruel thieves took him away when the dog escaped from his home.

    The 10-month-old dog had been missing since December and the broken-hearted boy even wrote a heartbreaking letter to Santa and posted it to Lapland asking for his pal back for Christmas.

    A £10,000 reward was offered by millionaire Simon Cowell after he read about the horrific theft. Cowell said: "It's heartbreaking to see a little boy's Christmas ruined. Dogs are so important to many of us. We just hope it helps lead to the safe return of Morse."

    His parents, Amanda Hopkins and Richard Latter, had given up hope of ever seeing their pet again, until they got a call on Friday night. A couple 20 miles away from their home in Marden, Kent, had found a muddy dog walking through their street and thought it could be missing Morse. They brought the Morse in, washed him, and then called Mr Latter who was unsure until he was sent a photo, and then drove the family to the village of Meopham.

    The theatre carpenter, 40, said: "Amanda and I were still quite sceptical, but Edward saw him and recognised him straight away. He was absolutely over the moon. He said: 'I can't believe it, I have my best friend back. It's too late for Christmas but this is the best present ever.' We were still unsure if it was him though—as he wasn't responding to his name or coming to us."

    "We spent about an hour and half over there and we still were not sure, so we took him home to get his chip scanned. It was only when we took him to the vets on Saturday morning and got his chip scanned that we found out for sure. We instantly broke down in tears. We were just hugging each other, hugging Edward and hugging the dog." Added Richard.

    The family who found missing Morse said they hadn't yet heard from Simon Cowell about the £10,000 reward hut were happy to get him home.

    Poet William Stafford once said that we are defined more by the detours(绕行路) in life than by the narrow road toward goals. I like this image. But it was quite by accident that I discovered the deep meaning of his words.

    For years we made the long drive from our home in Seattle to my parents' home in Boise in nine hours. We traveled the way most people do: the fastest, shortest, easiest road, especially when I was alone with four noisy, restless kids who hate confinement(限制) and have strong opinions about everything.

    Road trips felt risky, so I would drive fast, stopping only when I had to. We would stick to the freeways and arrive tired.

    But then Banner, our lamb was born. He was rejected by his mama days before our planned trip to Boise. I had two choices: leave Banner with my husband, or take him with me. My husband made the decision for me.

    That is how I found myself on the road with four kids, a baby lamb and nothing but my everlasting optimism to see me through. We took the country roads out of necessity. We had to stop every hour, let Banner shake out his legs and feed him. The kids chased him and one another. They'd get back in the car breathless and energized, smelling fresh from the cold air.

    We explored side roads, catching grasshopper in waist-high grass. Even if we simply looked out of the car window, at baby pigs following their mother, or fish leaping out of the water, it was better than the best ride down the freeway. Here was life. And new horizons(见识).

    We eventually arrived at my parents' doorstep astonishingly fresh and full of stories.

    I grew brave with the trip back home and creative with my disciplining technique.

    On an empty section of road, everyone started quarreling. I stopped the car, ordered all kids out and told them to meet me up ahead. I parked my car half a mile away and read my book in sweet silence.

    Some road trips are by necessity fast and straight. But that trip with Banner opened our eyes to a world available to anyone adventurous enough to wander around and made me realize that a detour may uncover the best part of a journey-and the best part of yourself.
