18．（6分） Over the past few months huge groups of locusts（蝗虫），one of which occupied an area more than three times the size of New York City，have eaten up crops across the Hom of Africa and the Middle East，leaving an estimated 20 million people at risk of famine（饥荒）．The first generation's eggs are starting to hatch， and now even bigger swarms（虫群）are forming threatening

Countries from the Democratic Republic of Congo to Yemen，Iran，Pakistan and India，\"representing a threat to food security and livelihoods，\" says the U．N．'s Food and Agriculture Organization（FAO）．

Desert locusts' populations explode when weather conditions are right． That explosion can create huge swarms that can travel great distance﹣more than 90 miles in a day﹣﹣﹣in search of food Warm weather and unusually heavy rains in the Horn of Africa at the end of 2019 provided the moist（湿润的）soil necessary for hatching eggs From there，the insects spread rapidly， resulting in one of the worst outbreaks the region has seen in more than 70 years．

A typical swarm numbering 4 billion to 8 billion locusts，can consume in one day the same amount of food as 35 million people．Some swarms have been so thick in parts of

第6页（共38页）

Kenya that they have prevented planes from taking off．Governments have used widespread aerial spraying of pesticides when available；in poorer regions，where aircraft are unavailable，soldiers battle the swarms with handheld spray pump．

The FAO has appealed for ＄138 million to support affected communities， If the locusts are not stopped before the next generation hatches， the impact could be terrible：the FAO guesses that an additional 25 million people across the region could lose their crops．Scientists in Kenya hope a new computer﹣assisted tracking program that combines satellite data with weather﹣mapping software will help predict the swarms 'next destination，buying﹣regional authorities enough time to prepare a response． Buy coronavirus﹣ related travel restriction have delayed relief efforts as well as response mechanisms．The locusts have/no such travel limitations．

（1）The author uses many statistics in the passage to show ． A．the disastrous consequence of the outbreaks of locusts B．the serious conditions facing the New York City C．the speed of swarms of locusts travelling D．the exact number of crops consumed by locusts （2）What is Paragraph 2 mainly about？ A．The great distances locusts can travel． B．The explosion of locusts' population． C．The perfect conditions for hatching their eggs． D．The result of the unusual outbreaks of locusts．（3）What does the last paragraph imply？

A．The travel restrictions may probably worsen the urgent situation． B．It is unlikely to predict the swarms' next destination now． C．A lot of money has been raised after the FAO 's appeal． D．It's not difficult for humans to win the battle against the locust．

19．（8分）Dog owners swear that their furry best mend is in tune with their emotions， Now it seems this sense of interspecies connection is real：dogs can smell your emotions，and adopt them as their own．

We already know dogs can see and hear the signs of human emotions says Biagio D'Aniello at the University of Naples Federico II，Italy But nobody had studied whether dogs could pick up on olfactory（嗅觉的）signals from humans．

\"The role of the olfactory system has been largely undervalued，maybe because our own species is more focused on the visual system．\" says D'Aniello． However dogs' sense of smelling is far superior to ours， D'Aniello and his colleagues tested whether dogs could really sniff out our emotions．First，human volunteers watched videos designed to induce fear， happiness or a neutral response and the team collected samples of their sweat． Next，the researchers presented these sweat samples to dogs ，and monitored their behaviour and heart rates．Dogs exposed to fear smells showed more signs of stress than those sniffing happy or neutral smells ，They also had higher heart rates，and made less social contact with strangers． D'Aniello's study suggests humans can unconsciously， hijack their dogs' emotion by releasing smells．A second study suggests dogs can return the favour，using their expressive faces．

Juliane Kaminski at the University of Portsmouth，UK，and her colleagues have found hat dogs' faces fare most expressive when they know people are looking at them．

The researchers introduced dogs to a human who was either looking at them or facing away．and either offering food or nothing． The team analyzed how much the dogs' facial movements varied in the four situations． They found that the dogs' facial expressions varied most when the person was looking at them． Kaminski says there was no sign of a \"dinner table effect\"， which \"would predict that dogs try and look super﹣cute when they want

第8页（共38页）

something from the humans\"．

It's not clear precisely how dogs visually signal us and how we respond， says Monique Udell of Oregon State University in Corvallis．\"This kind of research is needed to fully understand the nature of the human﹣dog relationship．\"

（1）How did D'Aniello's research team carry out their study on dog's ability of sniffing out humans' emotions？

A．By analyzing the sweat samples from the dogs． B．By monitoring dogs' response Co the same videos． C．By letting the dogs watch the volunteers' expressive faces． D．By watching the dogs' reactions to the given sweat samples．（2）The underlined word \"hijack\" Probably mean ． A．Study． B．Control． C．Find． D．Display．

（3）What can we infer from the second study？ A．Dinner﹣table effect really exists． B．Dogs are very sensitive to human attention．

C． Dogs showed no facial expression when offered nothing． D．Dogs' facial expressions vary most when they want attention．（4）What is still puzzling scientists according to the passage？ A．How dogs react to human smells． B．How dogs respond to humans' attention．

C．How dogs hear and see the signs of humans' emotions． D．How dogs communicate with humans by the sense of sightly．

④He stood up and looked around again． How could he make the sharks move out to sea？He put the knife against his leg and cut deep into the flesh，blood running out，He caught it on his white shirt．When the shirt was red and wet，he tied some cloths around his leg to stop the flow of blood．He tied a long piece of cloth to the shirt，then he threw the shirt into the water and

pulled it with a piece of cloth．

The sharks smelled the blood；they came racing toward the shirt．He was leading then away from shore．Suddenly he dropped the cloth turned toward shore and ran as fast as he could He jumped into the water and swam，He kicked and shouted as loud as he could．He touched the shore with his fingers and pulled himself up the stones．

The shark was excited by the smell of blood and the chase went after him；its great body crushed against the stones．The other sharks jumped on it The end came quickly as the sharks' blood turned the water red．The injured shark was eaten alive as it tried to escape． Perry slowly got to his feet．So，he said，\"you did not get me．\"

He looked down at the sharks still eating even though they were full of food．

The development of penicillin（1928﹣1945）

In 1928，Alexander Fleming was spending several weeks growing bacteria in piles of dishes for his experiment when he noticed a dish didn't look normal with blue mould in．Much to his astonishment，the mould killed the bacteria surrounding it．After discussing the blue mould with mould expert C．J．La Touche who had his office below Fleming's，they determined the mould to be a Penicillin mould．Fleming then called the active antibacterial agent in the mould，penicillin．He continued to run numerous experiments to determine the effect of the mould on other harmful bacteria，Surprisingly，the mould killed large number of them．He found the mould to be nontoxic and contain a powerful antibiotic．

In 1929，Fleming wrote a paper on his findings，which did not get any scientific interest．His penicillin was still in his lab far from an effective medicine because the development of Penicillin as a drug faced two problems．First，it was difficult for him to purify penicillin to work as a medicine．second， he was．Second，he was not able to produce penicillin in the ample quantities needed to be effective．

Fleming was praised for the discovery．but it was Howard Florey，Ernst Chain and their

spending several weeks growing bacteria in piles of dishes for his experiment when he noticed a dish didn't look normal with blue mould in.1928年，Alexander Fleming为了做实验，花了几周时间在成堆的盘子里培养细菌，这时他注意到一个盘子里有蓝色的霉菌，看起来不太正常．由此可知，在为他的实验培养细菌时，Fleming注意到盘子里有一些不太正常的东西，杀死了盘子周围的细菌．修饰不定代词something应用形容词abnormal /unusual作后置定语，表示\"不正常，不寻常的\"．故填abnormal /unusual．

（3）accident /chance / coincidence．细节理解题．根据第一段中Much to his astonishment， the mould killed the bacteria surrounding it．可知令他吃惊的是，霉菌杀死了周围的细菌．由此可知，Fleming在实验室无意中发现了这种蓝色霉菌，并将其命名为青霉素．表示\"偶然，无意间\"短语为by accident /chance/ coincidence．故填accident /chance / coincidence．（4）problems．原词重现题．根据第二段中His penicillin was still in his lab far from an effective medicine because the development of Penicillin as a drug faced two problems．可知由于盘尼西林作为药物的开发面临着两个问题，所以他的盘尼西林还远未成为一种有效的药物．由此可知，本部分是在介绍Fleming进一步研究的遇到的问题．有两个问题，所以problem应用复数形式．故填problems．

（5）difficulty /trouble/problems．原词重现题．根据第二段中First， it was difficult for him to purify penicillin to work as a medicine．可知首先，他很难把青霉素提纯成药物．由此可知，Fleming在使青霉素达到药物纯度标准方面遇到了困难．短语 have difficulty/trouble/ problems （in） doing sth．故填difficulty /trouble/problems．

（6）effective．原词重现题．根据第二段中Second， he was not able to produce penicillin in the ample quantities needed to be effective．可知第二，他无法生产出足够数量的青霉素，而这些青霉素必须是有效的．由此可知，Fleming无法生产出所需数量的有效青霉素．根据上文to be可知应填形容词effective，表示\"有效的\"．故填effective．

（7）succeeded．细节理解题．根据第三段中Fleming was praised for the discovery， but it was Howard Florey， Ernst Chain and their Colleagues at the Sir William Dunn School of Pathology at Oxford University who managed to turn penicillin from a lab curiosity into an effective drug．可知弗莱明因这一发现而受到赞扬，但正是牛津大学William Dunn爵士病理学院的Howard Florey、Ernst Chain和他们的同事们成功地将青霉素从实验室里的珍品变成了一种有效的药物．由此可知，另外两名科学家和他们的团队成功地使大规模生产成为可能．短语manage to do sth．等于succeed in doing sth．表示\"成功做某事\"．且事

第36页（共38页）

情发生在过去，应用一般过去时．故填succeeded．

（9）used /employed．细节理解题．根据第四段中The wide use of penicillin during World War II saved many lives． Without it， many people would have died due to bacterial infections in even minor wounds．可知第二次世界大战期间青霉素的广泛使用挽救了许多人的生命．如果没有它，许多人会死于细菌感染，甚至是小伤口．由此可知，广泛使用青霉素治疗病人，挽救了许多生命，否则这些生命将会死去．表示\"使用\"可用动词use或employ，且分析句子结构可知use/employ在句中作非谓语动词，与逻辑主语penicillin构成被动关系，故用过去分词．故填used /employed．

（10）won /shared．细节理解题．根据最后一段中All three of them were awarded the 1945 Nobel Prize in Physiology or Medicine．可知他们三人都获得了1945年诺贝尔生理学或医学奖．由此可知，1945年后，青霉素开始了医药革命，Fleming、Florey和Chain因他们的研究获得了诺贝尔医学奖．表示\"赢得，分享\"应用动词win或share，且事情发生在过去应用一般过去时．故填won/shared．第五部分书面表达
