He lay at full length upon his stomach, his head upon th

2、e left forearm.His extended right hand loosely grasped his gun. But for the slight rhythmic movement of his back, he might have been thought to be dead. He was asleep at his post of duty. But if found, he would be dead shortly afterward, death being the just and legal penalty for his crime. The slee

3、ping soldier was a young Virginian named Carter Druse. He was the son of wealthy parents, an only child. His home was but a few miles from where he now lay. One morning he had risen from the breakfast table and said, quietly but gravely, “Father, the Union Army has arrived at Grafton, I am going to

4、join it.” The father lifted his head, looked at the son for a moment in silence, and replied, “Go, Carter, and whatever may occur, do what you consider to be your duty. Virginia, which you betray, must get on without you. Should we both live to the end of the war, we will speak further of the matter

5、. Your mother, as the physician has informed you, is in a most critical condition; at best she cannot be with us longer than a few weeks, but that time is precious. It would be better not to disturb her.” So Carter Druse, bowed to his father and left the home of his childhood. By conscience and cour

6、age, he was soon well received by his fellows and his officers; and it was to these qualities and to some knowledge of the country that he owed his selection for his present duty at the extreme post. Nevertheless, he fell asleep, exhausted. What good or bad angel came in a dream to awake him from hi

7、s state of crime, who shall say? He quietly raised his forehead from his arm and looked between the laurels. His first feeling was a keen artistic delight. On the cliff was a statue of impressive dignity. The figure of the man sat on the horse, straight and soldierly. The face of the rider, turned s

8、lightly away; he was looking downward to the bottom of the valley. Broad awake and keenly alive now, Druse cautiously pushed the gun forward through the bushes and covered a vital spot of the horsemans breast. A touch upon the trigger (扳机) and all would have been well with Druse. At that instant the

9、 horseman turned and looked in his direction seemed to look into his very face, into his eyes, into his brave heart. Druse grew pale; he shook in every limb (肢) and turned faint. His hand fell away from his weapon, his head slowly dropped until his face rested on the leaves in which he lay. The duty

10、 of the soldier was plain the man must be shot dead. But no there is a hope; he may have discovered nothing perhaps he is but admiring the beauty of the landscape. Druse turned his head and looked through the deeps of air downward. He saw some foolish commander was permitting the soldiers to water t

11、heir beasts in the open! 高考资源网（ ） 您身边的高考专家 版权所有高考资源网 - 2 - Druse withdrew his eyes from the valley and fixed them again upon the group of man and horse in the sky, and again it was through the sights of his gun. But this time his aim was at the horse. In his memory rang the words of his father, “Wha

12、tever may occur, do what you consider to be your duty.” He fired. Ten minutes had hardly passed when a Federal officer crept cautiously to him. “Did you fire？” the officer whispered. “Yes.” “At what？” “A horse. It was standing on the rock, pretty far out. You see it is no longer there. It went over

13、the cliff.” The mans face was white, but he showed no other sign of emotion. Having answered, he turned away his eyes and said no more. The officer did not understand. “See here, Druse，” he said, after a moments silence, “its no use making a mystery. I order you to report. Was there anybody on the h

14、orse？” “Yes.” “Well？” “My father.” 语篇解读：本文是一篇记叙文。文章讲述了富家子弟 Carter Druse 在父亲的同意下参加了联邦 军队并忠于职守的故事。 1. What can we learn from the first paragraph? AThe soldier was thought to be dead.

19、此 可知，作者想要通过这个故事告诉读者战争的残酷。故选 C。 B (2019 徐州、淮安、连云港模拟)When a caterpillar (毛虫) pretends to be a snake to keep off potential predators (捕食者), it should probably expect to be treated like one. This is exactly what happened in Costa Rica earlier this year, when researchers witnessed a hummingbird defending

20、 its nest from what it interpreted to be a snake, but was actually a caterpillar, which was feeding on a leaf above the nest. These caterpillars resemble flat dried leaves as adults. They can expand the top of their heads to expose a pair of eyespots that discourage potential predators. When disturb

21、ed, they raise their heads up and move from side to side, increasing the snake- like appearance. In particular they resemble green parrot snakes, known to feed on nesting birds. Hummingbirds have a few styles of flying: visiting flowers, feeding on some tiny insects, chasing each other, and mating t

22、erritory (领土) display flight. Mobbing (围攻) behavior directed against a threat to their nest is much less common but easy to recognize if you know their flight behaviors. The interaction of the caterpillar and the hummingbird took place in Costa Rica. The comings and goings of the female hummingbird

23、around its nest may have disturbed the caterpillar, causing it to expose its eyespots, which in turn caused the hummingbird to defend its nest using what is referred to as “mobbing behavior” by birds. 高考资源网（ ） 您身边的高考专家 版权所有高考资源网 - 4 - The caterpillar was unable to feed during the 26- minutes of near

24、ly continuous attacks. Most of the birds movements were cautious, but included quick attacks to peck or bite the eyespots. It was difficult for either the bird or the caterpillar to withdraw from the standoff (僵局), with the hummingbird protecting its nest and the caterpillar just trying to finish it

25、s leafy meal. Eventually the caterpillar gave up on eating and crawled away while still under attack, and the hummingbird continued normal nesting behavior. When birds exhibit this mobbing behavior targeting snakes eyes, it often ends with snakes being killed by repeated bites and pecks near the hea

26、d. As for creatures that imitate snakes to protect themselves from being eaten, can they in turn protect themselves? Because the hummingbirds behavior was typical anti- snake behavior, it can be considered replicable (可复制的) Future studies of this behavior can be conducted using a tiny, caterpillar r

27、obot. It should be remotely controlled, light enough to attach to a leaf or stem, and wireless. With such a robot, researchers could vary the eye- like nature and contrast of spots on the head of the robot to test various responses of nest- defending birds. A study like this could definitively test

28、the effects of eye- like versus other imitating patterning for exciting the defensive attacks. And, it turns out that the caterpillar feeds on a leaf on the same plant, as far away from the nest as possible! 语篇解读：本文是一篇说明文。研究人员观察到蜂鸟为了护巢，攻击伪装成蛇的毛虫，伪装 的毛虫有膨胀的头和眼点，于是研究人员就想明确地测试类似眼睛和其他模仿模式对激发防 御攻击的影响。 5.

29、 What do we know about caterpillars and hummingbirds from the passage? AThey belong to the same species. BThey are natural enemies of each other. CThey are insects and birds respectively. DThey compete against each other for territory. 解析：选 C 推理判断题。根据第一段内容可知，hummingbird(蜂鸟)需要保护自己的巢不 受蛇的破坏，蛇其实是 cater

30、pillar(毛虫)伪装的，毛虫只是为了吃鸟巢上方的叶子，但是为 了躲避攻击，假扮成蛇，故选 C。毛虫与蜂鸟不是天敌关系，排除 B，也不互相争夺领地， 排除 D。 6Hummingbirds will show their mobbing behavior when visitors _. Aare picking flowers Bare chasing each other Cinterrupt their eating leaves Dset foot on their territories 解析： 选 D 细节理解题。 根据第三段中的“Mobbing (围攻) behavior di

Why is neither the hummingbird nor the caterpillar willing to w

32、ithdraw at first? A. Because the hummingbird is trying to finish its leafy meal. BBecause the caterpillar is protecting the hummingbirds nest. CBecause they behave in this way out of their own interest. DBecause there is a green parrot snake watching them. 解析：选 C 细节理解题。根据第六段可知，蜂鸟需要保护自己的巢，毛虫为了进食，所 以双

33、方僵持不下。它们的表现都是出于保护自身的利益，故选 C。 8. A tiny caterpillar robot can be used to _. Aimitate the anti- snake behavior Btest nest- defending birds responses Ctake control of the snakes behavior Dguard against the defensive attacks 解析：选 B 细节理解题。根据倒数第二段第三句“With such a robot, researchers could vary the eye- like

34、 nature and contrast of spots on the head of the robot to test various responses of nest- defending birds.”可知，毛虫机器人可以用来测试护巢鸟类的反应。故选 B。 C (2019 南京、盐城模拟)Listen carefully to the footsteps in the family home, especially if it has wooden floors, and you can probably work out who it is that is walking abo

35、ut. The features most commonly used to identify people are faces, voices, finger prints and retinal scans. But their“behavioural biometrics”， such as the way they walk, are also giveaways. Researchers have, for several years, used video cameras and computers to analyse peoples gaits, and are now qui

36、te good at it. But translating such knowledge into a practical identification system can be tricky especially if that system is supposed to be hidden. Cameras are often visible, are hard to set up, require good lighting and may have their view blocked by other people. So a team led by Krikor Ozanyan

37、 of the University of Manchester, in England and Patricia Scully of the National University of Ireland, in Galway have been looking for a better way to recognise gait. Their answer: pressure- sensitive mats. In themselves, such mats are nothing new. They have been part of security systems for donkey

38、s years. But Dr Ozanyan and Dr Scully use a complex version that can record the amount of pressure applied in different places as someone walks across it. These measurements form a pattern unique to the walker. Dr Ozanyan and Dr Scully therefore turned, as is now common for anything to do with patte

39、rn recognition, to an Artificial Intelligence system that uses machine learning to recognise such patterns. It seems to work. In a study published earlier this year the two researchers tested their system 高考资源网（ ） 您身边的高考专家 版权所有高考资源网 - 6 - on a database of footsteps trodden by 127 different people. T

40、hey found that its error rate in identifying who was who was a mere 0.7%. And Dr Scully says that even without a database of footsteps to work with the system can determine someones sex women and men, with wide and narrow pelvises (骨盆) respectively, walk in different ways, and guess, with reasonable

41、 accuracy, a subjects age. A mat- based gait- recognition system has the advantage that it would work in any lighting conditions even pitch- darkness. And though it might fail to identify someone if, say, she was wearing stilettos and had been entered into the database while wearing trainers, it wou

42、ld be very hard to fool it by imitating the gait of an individual who was allowed admission to a particular place. The latest phase of Dr Ozanyans and Dr Scullys project is a redesign of the mat. The old mats contained individual pressure sensors. The new ones contain optical fibres (光纤). Light- emi

43、tting diodes (二极管) distributed along two neighbouring edges of a mat transmit light into the fibres. Sensors on the opposite edges (and thus the opposite ends of the optical fibres) measure how much of that light is received. Any pressure applied to part of the mat causes a distortion (变形) in the fi

44、bres and a consequent change in the amount of light transmitted. Both the location and amount of change can be plotted and analyzed by the machine- learning system. Dr Ozanyan says that the team have built a demonstration fibre optic mat, two meters long and a metre wide, using materials that cost 1

45、00(D|S130). They are now talking to companies about commercializing it. One application might be in health care, particularly for the elderly. A fibre optic mat installed in a nursing home or an old persons own residence could monitor changes in an individuals gait that warn certain illnesses. That

46、would provide early warning of someone being at greater risk of falling over, say, or of their cognition becoming damaged. Gait analysis might also be used as a security measure in the workplace, monitoring access to restricted areas, such as parts of military bases, server farms or laboratories dea

47、ling with harmful materials. In these cases, employees would need to agree to their gaits being scanned, just as they would agree to the scanning of their faces or retinas for optical security systems. Perhaps the most fascinating use of gait- recognition mats, though, would be in public places, suc

48、h as airports. For that to work, the footsteps of those to be recognised would need to have been stored in a database, which would be harder to arrange than the collection of mugshots and fingerprints that existing airport security systems rely on. Some people, however, might volunteer for it. Many aircre
