I became terribly nervous. I fumbled (胡乱摸找) in my pockets to see if there was any cigarette, which had es
8、caped their search. I found one and because of my shaking hands, I could barely get it to my lips. But I had no matches. They had taken those. I looked through the bars at the guard. He did not make eye contact with me. I called out to him, “Have you got a light?” He looked at me, shrugged and came
9、over to light my cigarette. As he came close and lit the match, his eyes unconsciously locked with mine. At that moment, I smiled. I didnt know why I did that. Perhaps it was nervousness;perhaps it was because, when you got very close to one another, it was very hard not to smile. In any case, I smi
10、led. In that instant, it was as though a spark jumped across the gap between our two hearts, our two human souls. I knew he didnt want to, but my smile leaped through the bars and caused a smile on his lips, too. He lit my cigarette but stayed near, looking at me directly in the eye and continuing t
11、o smile.I kept smiling at him, thinking of him as a person and not just a guard. “Do you have kids?” he asked. “Yes, here, here,” I took out my wallet and nervously fumbled for the pictures of my family. He, too, took out the pictures of his family and began to talk about his plans and hopes for the
12、m. My eyes filled with tears. I said I feared that Id never see my family again, and never have the chance to see them grow up. Tears came to his eyes, too. Suddenly, without another word, he unlocked my cell and silently led me out. Out of the prison, quietly and by a back route. At the edge of tha
13、t town, he released me. And without another word, he turned back toward the prison.4.What had happened to the man before?A.He had been badly treated.B.He had killed someone.C.He had been searched.D.He had been forbidden to get in touch with anyone.5.Why did the man want to smoke cigarettes?A.Because

Rays of sunshine pierced through the
16、trees, the hard soil crunched beneath his feet and birds conducted their own orchestra. But Beethoven wasnt amazed at these details. Some years earlier, he had started to lose his hearing. He still persevered with his work, and went on creating timeless music. But he found little joy in the process.
17、Today, 466 million people worldwide have disabling hearing loss, and over 900 million are expected to have it by 2050, according to the World Health Organization. Its impact is often underestimated compared with other disabilities, and people with hearing loss constantly experience communication dif
18、ficulties in their everyday lives. They often mishear the speech and find it very difficult to follow conversations. The miscommunication can lead individuals to feel isolated as they struggle to take part in social interactions, and ultimately lead them to withdraw from society. As Helen Keller onc
19、e wrote:Blindness cuts us off from things, but deafness cuts us off from people.To this day, there is still no cure for sensorineural(感觉神经性的) hearing loss (the most common type, and the one Beethoven had). We have advanced technological devices that strengthen the sound, such as hearing aids and coc
20、hlear implants(人工耳蜗), but these still dont restore hearing. Scientists have been studying the regeneration process of hair cells in non-mammals, and they have identified various genes and proteins that have central roles. These can be targeted to stimulate support cells in the cochlea to create more
21、 hair cells and replace those that died. Some of these cell therapies have been successful in restoring the hearing of mice and guinea pigs: a breakthrough! If it works, such a scientific advance could transform hearing health care.When Beethoven lost his hearing, he separated himself from society,
22、but one thing that gave him strength was the hope that his hearing could be regained one day. But each medical remedy he attempted failed. In 1802, he wrote:But thinking that for six years now, I have been hopelessly afflicted, made worse by senseless physicians, from year to year cheated by hopes o

26、rom animals into humans. When infections do this they can be deadlyand COVID-19 is no exception.Many viruses that jump into people, like MERS, seldom spread from person to person. They can still infect thousands, though; rabies(狂犬病) is mostly passed on by dog bites, but kills 60,000 people a year. O
27、thers, such as Ebola, can spread from person to person, but arent very good at it and so cause relatively small outbreaks. COVID-19, by contrast, appears quite good at spreading from person to person. While we dont know how deadly it is, Chris Coleman, a professor at the University of Nottingham, th
28、e UK, says, “Its not the most deadly coronavirus weve ever had.”To trace the new viruss origins, researchers have been comparing its genome to that of other coronaviruses. This showed that it possibly derives from a strain that infects bats. “Its highly related to bat coronaviruses,” says Vaithiling
29、araja Arumugaswami at the University of California, Los Angeles. This makes sense as bats are known to harbour many viruses, including coronaviruses. Viral infections are especially likely to spread among bats as they can fly long distances and roost close to each other. Bats also seem able to carry
30、 infections without getting ill, which helps spread the viruses. The new coronavirus might have jumped from bats into another animal a few months or even a few decades ago, and then from that intermediate host into humans. We know that the coronavirus behind the SARS outbreak of 2002 to 2003 spread
31、from bats into palm civets(狸猫) before infecting people.Viruses that normally circulate among people can gradually become less lethal, as this helps them spread. “They dont want you to drop dead within a day because you wont pass it to anyone else,” says Chris Coleman.Coleman thinks there is little w
32、e can do to stop people coming into contact with animals that may carry dangerous viruses. “Its very difficult to control that,” he says. Instead, he says we need to have vaccines ready in advance. This could mean creating vaccines that are effective against a wide range of viruses or vaccines that
33、require only minor tweaks to work against a new viral strain, much like annual flu vaccines.12.Whats the second paragraph mainly about?A.The intermediate host of viruses.B.The mode of virus transmission.C.The outbreak of the deadly COVID-19.D.The serious consequence of COVID-19.13.Why does the autho
34、r mention SARS in the text?A.To support an idea.B.To study virus infections.C.To trace the coronaviruss origins.D.To map the new viruss genome.14.Whats the meaning of the underlined word “lethal”?A.Complicated.B.Active.C.Healthy.D.Deadly.15.According to Coleman, what do we need to do to fight agains
