21、 In 2018 biologist Jann Vendetti published a paper that described the discovery of five species of non-native snails and slugs（蜗牛和鼻涕虫）in Southern California. The research would not have been possible without some 1,200 volunteers who uploaded nearly 10,000 photos to the SLIME project (Snails and Slugs Living in Metropolitan Environments) on an app called iNaturalist.
“So the entire existence of that paper is dependent upon these citizen scientists. How do you credit those people?” said Greg Pauly from the Natural History Museum of Los Angeles. “There are some very specific requirements that a lot of journals and a lot of academic societies use. And those requirements largely would exclude nonprofessional scientists. And to me, that’s absurd.” That’s why Pauly, together with Vendetti, and several Australian biologists are arguing that criteria must change to recognize citizen scientists as authors on scientific journal articles.
They propose what they’re calling “group co-authorship.” The author list on Vendetti’s snail-and-slug paper includes the phrase “citizen science participants in SLIME.” But the phrase is absent when you look up the paper on Google Scholar. The publication software simply isn’t equipped to handle that kind of authorship, and so it erases the group’s vital contribution.
In another case, several years ago in Australia, a team of researchers tried to condition native lizards not to eat the poisonous cane toads. The only reason it was successful was because they partnered with the traditional landowners in northwestern Australia, and this group was called the Balanggarra Rangers.
Several journals flat-out refused to allow for the inclusion of the Rangers as group co-authors. Eventually, the researchers did convince the editors of some journals to allow it, but the group’s title was shortened, as if it was a first and last name, in online indexing software: “B. Rangers.”
The researchers argue that these errors and omissions don’t only make the critical contributions of a native community as invisible, they could also be seen as showing prejudice.
“If the person who had made that contribution was a graduate student who was trying to pursue a career in the sciences, we would all say, ‘Oh, of course that person should be a co-author’. But we don’t necessarily extend that same line of reasoning to citizen scientists.”
Allowing for group co-authorship is not a new idea. In 2004 the journal Nature published a paper titled “Initial Sequencing and Analysis of the Human Genome.” It listed as the sole author the “International Human Genome Sequencing Association.” “So let’s just choose this group-authorship model and turn it into group co-authorships. This really shouldn’t be that hard.”

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.

24、A serious problem for today’s society is who should be responsible for our elderly and how to improve their lives. It is not only a financial problem but also a quashing of the system we want for our society. I would like to suggest several possible solutions to this problem.
First, employers should take the responsibility for their retired employees. To make this possible, a percentage of profits should be set aside for this purpose. But when a company must take life-long responsibility for its employees, it may softer from a commercial disadvantage due to higher employee costs.
Another way of solving the problem is to return the responsibility to the individual. This means each person must save during his working years to pay for his years of retirement. This does not seem a very fair model since some people have enough trouble paying for their daily life without trying to earn extra to cover their retirement years. This means the government might have to step in to care for the poor.
In addition, the government could take responsibility for the care of the elderly. This could be financed through government taxes to increase the level of pensions. Furthermore, some institution should be created for senior daises, which can help provide a comfortable life for them. Unfortunately, as the present situation in our country shows, this is not a truly viable answer. The government can seldom afford to care for the elderly, particularly when it is busy trying to care for the young.
One further solution is that the government or social organizations establish some working places especially for the elderly where they are independent.
To sum up, all these options have advantages and disadvantages. Therefore, it is reasonable to expect that some combination of these options may be needed to provide the care we hope to give to our elderly generations.
【1】What is the passage mainly about?
A．The problems faced by the old in society.
B．Why we should take responsibility for the old.
C．How we can improve the lives of the old.
D．Where the old can go to get their pensions.
【2】According to the passage, how can the government help to improve the lives of retired people?
A．Set aside some profits to help people with problems after they retire.
B．Increase savings levels of people during their working years.
C．Increase the discounts for food and transport for the old.
D．Make available pensions for those who have retired.
【3】The underlined word “viable” most probably means “ ”.
A．impossible
B．practical
C．useful
D．successful
【4】What can be concluded from the passage?
A．Taking care of the old is mainly an issue of money.
B．Employers should allow their workers to retire at a later age.
C．Becoming independent should be the goal of most old people.
D．There is no single solution to the problems of the old.
【5】What is the writer’s main purpose in writing this article?
A．To point out the need for government supped for old people.
B．To make general readers aware of the problems of retired people.
C．To discuss some possible solutions to an important social problem.
D．To instruct retired people on how they can have a happier life.

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'm going to miss you so much, Poppy, "said the tall, thin teenager. He bent down to hug his old friend goodbye. He stood up, hugged his parents, and smiled, trying not to let his emotions(情绪)get the better of him.
His parents were not quite able to keep theirs under control. They had driven their son several hours out of town to the university where he would soon be living and studying. It was time to say goodbye for now at least. The family hugged and smiled through misty eyes and then laughed.
The boy lifted the last bag onto his shoulder, and flashed a bright smile.” I guess this is it, “he said.” I'll see you back home in a month, okay？"His parents nodded, and they watched as he walked out of sight into the crowds of hundreds of students and parents. The boy's mother turned to the dog, “Okay, Poppy, time to go back home.”
The house seemed quiet as a tomb without the boy living there. All that week, Poppy didn't seem interested in her dinner, her favorite toy, or even in her daily walk. Her owners were sad too, but they knew their son would be back to visit. Poppy didn't.
They offered the dog some of her favorite peanut butter treats. They even let her sit on the sofa, but the old girl just wasn't her usual cheerful self. Her owners started to get worried. "What should we do to cheer Poppy up？"asked Dad. “We've tried everything.”
“I have an idea, but it might be a little crazy, “smiled Mom.” Without anybody left in the house but us, this place could use a bit of fun. Let's get a little dog for Poppy."
It didn't take long before they walked through the front door carrying a big box. Poppy welcomed them home as usual, but when she saw the box, she stopped. She put her nose on it. Her tail began wagging(摆动)ever so slowly, then faster as she caught the smell.
