Mars is the obvious first choice for travel to other planets. Of all the other planets in the Solar System, Mars even with i ts present cold, hostile environment is the most like Earth. About half Earth‘s diameter with one-third the gravity and only 1 percent of the atmosphere, spacecrafts have found that Mars nonetheless harbors the important asset of water beneath its surface and in its frozen poles.Every two years its orbit draws it closer to Earth, and its presence in the night sky is a constant reminder of what might be. Last summer, it came within 34.6 million miles of Earth, its nearest approach in almost 60,000 years.Only Venus is closer, and with an average temperature of about 850 degrees, it is not welcoming. In contrast, Mars ispleasantly cool, from about 200 degrees below zero right up to freezing.From the presence of water and relatively temperate climate comes another powerful attraction. ―The fascination with Mars centers around the issue of life,‖ Dr. Zubrin said. ―Mars is key to answering that critical question, is there life so mewhere other than Earth?‖Dr. Louis D. Friedman, executive director of the Planetary Society, said, ―The fundamental question people want answered is ‗Where am I from and where am I going?‘‖ He added, ―Mars can tell us about the origin of life and the destiny of life. Finding evidence of past or present life, even if only primitive microbes, would mean that life did not occur only on E arth‖, he said. ―And‖, he said, ―Mars is the only planet we know of that humans have a chance of colonizing to prove they will not be forever Earth-bound.‖―Mars becomes the experiment,‖ Dr. Friedman said. ―If we can‘t make it on Mars, then Earth is our limit and we are going to have to re-examine our relationship to our home planet.‖(1)Mars is the obvious first choice for travel to other planets, because_______. [本题2分] 正确答案：B(A) Mars is cold and hostile (B) The environment of Mars is most similar to that of Earth.(C) Mars has about half Earth‘s diameter, one-third the gravity and 1 percent of the atmosphere(D) Spacecrafts have found water on Mars.(2)According to the passage, which of the following statement is true? [本题2分] 正确答案：D(A) Earth is cold and hostile, just like Mars. (B) Mars is much bigger than Earth.(C) Mars is closest to Earth of all the other planets in the solar system.(D) Venus isn‘t an ideal choice for man to travel because of its high temperature.(3)According to Dr. Zubrin, people are fascinated with Mars because _______. [本题2分] 正确答案：C(A) Mars has water beneath its surface and in its frozen poles. (B) Mars has a relatively temperate climate.(C) Mars is key to answering ―Is there life somewhere besides Earth?‖ (D) Mars is very beautiful.(4)Which is NOT mentioned by Dr. Louis D. Friedman? [本题2分] 正确答案：C(A) Finding evidence of past or present life on Mars would mean that life did not occur only on Earth.(B) Mars can tell us about the origin of life and the destiny of life. (C) Mars is the only star that humans have a chance of reaching. (D) If we can‘t make it on Mars, Earth has to be our limit.(5)We may describe this passage as ________. [本题2分] 正确答案：C(A) entertaining (B) imaginative (C) scientific (D) humorous42. For over a decade, the technique of distraction has been researched and successfully applied in clinical practice in order to reduce pain associated with certain medical procedures. Distraction techniques are based on the patient‘s limited capacity f or attentio n, resulting in a reduction in the patient‘s attention to the stimulus and therefore a reduction in the stimulus itself. It was assumed that the ideal distracter would require an optimum amount of attention involving various senses (visual, auditory and kinesthetic), an active emotional involvement, and participation from the patient to compete with the signals of the harmful stimuli.The advanced distraction techniques (ADTs) recently developed use 3D images combined with dynamic audio stimuli, making the techniques more likely to meet the requirements of an ideal distracter than the traditional distraction methods such as watching a film or playing a simple computer game.The ADTs simulate real-life situations, and the possibilities are infinite. For example, until now users could choose between taking a flight, driving, downhill skiing, exploring buildings and many more activities.In this study, peer-reviewed publications on ADTs and pain have been reviewed to determine the clinical effectiveness and importance of using these techniques as an analgesic. The results suggest that the ADTs can significantly reduce the pain associated with medical treatment. The use of such analgesia was clinically revealed in most cases, especially in patients with very high or unbearable levels of pain. It was found that levels of anxiety were reduced during the exposure, and the side effects, such as ‗simulator sickness‘, were hardly observed at all.We can conclude that ADTs are very useful as analgesia, and can reduce the amount of analgesic administered. This new field of study can begin to move forward beyond its current initial phase by placing more emphasis on methodology and psychological aspects.(1)Which is NOT the reason why distraction techniques can reduce the patient’s pain? [本题2分] 正确答案：A(A) Because distraction techniques can remove the pain out of the patient‘s body.(B) Because distraction techniques are based on the patient‘s limited capacity for attention.(C) Because d istraction techniques can cause a reduction in the patient‘s attention to the stimulus and therefore a reduction in the stimulus itself.(D) Because distraction techniques would require various senses, an active emotional involvement, and participation from the patient to compete with the signals of the harmful stimuli.(2)That ADTs is better than the traditional distraction methods because _______. [本题2分] 正确答案：C(A) ADTs include watching a film or playing a simple computer game.(B) ADTs require people to take a flight, driving , downhill skiing, exploring buildings, etc.(C) ADTs use 3Dimages combined with dynamic audio stimuli. (D) ADTs are used in real-life situations.(3)According to Para. 4, when ADTs are used, which of the following will NOT happen? [本题2分] 正确答案：A(A) The pain associated with medical treatment has completely gone. (B) Levels of anxiety were reduced during the exposure. (C) The side effects, such as ‗simulator sickness‘, were hardly observed at all. (D) ADTs can significantly reduce the pain relevant to medical treatment.(4)From the last paragraph, we know that________. [本题2分] 正确答案：B(A) The effect of ADTs are the same as that of analgesia. (B) We can reduce the amount of analgesia with the help of ADTs. (C) We can replace analgesia with ADTs. (D) We have already achieved success in the study of distraction techniques.(5)This passage mainly talks about________ [本题2分] 正确答案：A(A) distraction techniques that help ease pain during medical treatment. (B) the relation between ADTs and traditional distraction methods. (C) the advantages of using ADTs over analgesic. (D) the difference between ADTs and traditional distraction methods.43. How can we get rid of garbage (垃圾)? Do we have enough energy sources to meet out future energy needs? These are two important questions that many people are asking today. Some people think that we might be able to solve both problems at the same time. They suggest using garbage as an energy source.For a long time people have buried garbage, or dumped (倾倒) it on empty land. Now while empty land is getting scarce, more and more garbage is being produced each year. Fortunately, garbage can be a good fuel (燃料) to use. The things in garbage do not look like coal, petroleum (石油), or natural gas; but they are chemically similar to these fossil fuels. As we use up our fossil-fuel supplies, we might be able to use garbage as an energy source.Burning garbage is not a new idea. Some cities in Europe and America have been burning garbage is used to boil water. The steam that is produced is used to make electricity or to heat nearby buildings. In Paris, France, some power plants burn almost 2 million tons of the city‘s garbage each year. The amount of energy produced is the same as would be produced by burning almost a half million barrels of oil!But there are problems in using garbage as a fuel. Some garbage that burns easily, like food scraps (残渣，碎末) and paper, must be separated from metals, glass, and other materials that do not burn easily. This separation process is normally costly. Another problem is that burning garbage can pollute the air.Our fossil fuel supplies are limited. Burning garbage might be one kind of energy source that we can use to help meet our energy needs. This method could also reduce the amount of garbage piling up on the earth.(1)Burning garbage can solve two problems －________. [本题2分] 正确答案：A(A) The shortage of energy and too much garbage on the earth.(B) The shortage of energy and the shortage of empty land for holding garbage.(C) Air pollution and the shortage of fossil fuel. (D) Air pollution and the shortage of energy.(2)According to the passage, which of the following statements is NOT true? [本题2分] 正确答案：D(A) The steam produced is used to make electricity. (B) The heat produced is used to boil water.(C) The steam produced is used to heat buildings. (D) The garbage burned is turned into fossil fuels.(3)According to the passage, which kind of garbage can be burnt directly? [本题2分] 正确答案：B(A) Metals and paper. (B) Food scraps and paper (C) Glass and food scraps. (D) Metals and glass.(4)Garbage is similar to _______ chemically. [本题2分]正确答案：B(A) natural gas (B) fossil fuels (C) metals (D) glass(5)Which of the following can be the best title for the passage? [本题2分] 正确答案：C(A) Environmental Protection (B) Use of Garbage (C) Garbage-An Energy Source (D) Garbage Disposal44. Do you forget to turn off the lights and heaters when you go out of a room? In 2040 it will not matter. They will turnthemselves off－and on again when you return. You will choose the temperature for each room, the lighting and the humidity. A sensor will detect the presence of a human (and, with luck, ignore the dog!) and turn the systems on, and when the humans leave it will turn them off again.The sensors will work through the central home computer, and they will do much more than just turn the fires and lights on and off for you. They will detect faulty electrical appliances, plugs or switches, isolate them so that they cannot harm anyone, and then warn you that they need repair. They will detect fire and if you are out of the house, the computer will call the fire brigade. It will also call the police if the sensors detect an intruder. This will not be too difficult because the locks on the outside doors will be electronic. You will open them using your personal card—the one you use for shopping－maybe using a number known only to you.It will be impossible to lose the key, and a housebreaker will have to tamper (拨弄) with the lock or with a window. It is not very difficult to make such tampering send a signal to the computer.The computer will be more than a fireman, policeman, or servant. It will be an entertainer, and most of your entertainment will come right into your home. It does now, of course, but by 2040 "entertainment" will mean much more. For one thing, you will be able to take part actively, rather than just watching.(1)We can learn from the passage that _______ in 2040. [本题2分] 正确答案：D(A) computer will do everything for us (B) we will live without the lights and heaters(C) switches will be unnecessary for lights and heaters (D) lights and heaters will be on and off automatically(2)Which of the following statements is true? [本题2分] 正确答案：A(A) You can be taken for an intruder lf you tamper with the lock or with a window. (B) Without a computer, the sensor can also do much in 2040. (C) The sensor will detect fire and make an emergency call. (D) The sensor is in fact a computer.(3)According to the author, in 2040, computer will NOT be regarded as a (an) _______. [本题2分] 正确答案：C(A) fireman (B) entertainer (C) babysitter (D) policeman(4)Owing to computer, in 2040, people will _______. [本题2分] 正确答案：B(A) be controlled by computers (B) have more fun at home (C) have no entertainment outside (D) replace TV with computers(5)Which of the following can be the best title of the passage? [本题2分] 正确答案：C(A) The Relation between Sensors and Computers (B) The Development of Computers(C) Life at Home in the Year 2040 (D) The Effect of Computers in the Year 2040参考答案：[第三单元]; 第5小题：C 推断题。

2023年12月英语六级真题含答案

12月大学英语六级考试真题（第1套）Section CDirections:There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C) and D). You should decide on the best choice and mark the corresponding letter on Answer Sheet 2 with a single line through the centre.Passage OneQuestions 56 to 60 are based on the following passage.Among the government’s most interesting reports is one that estimates what parents spend on their children. Not surprisingly, the costs are steep. For a middle-class, husband-and-wife family (average pretax income in : $76,250), spending per child is about $12,000 a year. With inflation the family’s spending on a child will total $286,050 by age 17.The dry statistics ought to inform the ongoing deficit debate, because a budget is not just a catalog of programs and taxes. It reflects a society’s priorities and values. Our society does not—despite rhetoric(说辞) to the contrary—put much value on raising children. Present budget policies tax parents heavily to support the elderly. Meanwhile, tax breaks for children are modest. If deficit reduction aggravates these biases, more Americans may choose not to have children or to have fewer children. Down that path lies economic decline.Societies that cannot replace their populations discourage investment and innovation. They have stagnant (萧条) or shrinking markets for goods and services. With older populations,theyresist change. To stabilize its population—discounting immigration—women must have an average of two children. That’s a fertility rate of 2.0.Many countries with struggling economies are well below that.Though having a child is a deeply personal decision, it’s shaped by culture, religion, economics, and government policy. “No one has a good answer” asto why fertility varies among countries, says sociologist Andrew Cherlin of The Johns Hopkins University. Eroding religious belief in Europe may partly explain lowered birthrates. In Japan young women may be rebelling against their mothers’ isolated lives of child rearing. General optimism and pessimism count. Hopefulness fueled America’s baby boom. After the Soviet Union’s collapse, says Cherlin, “anxiety for the future” depressed birthrates in Russiaand Eastern Europe.In poor societies, people have children to improve their economic well-being by increasing the number of family workers and providing supports for parents in their old age. In wealthy societies, the logic often reverses. Government now supports the elderly, diminishing the need for children. By some studies, the safety nets for retirees have reduced fertility rates by 0.5 children in the United States and almost 1.0 in Western Europe, reports economist Robert Stein in the journal National Affairs. Similarly, some couples don’t have children because they don’t want to sacrifice their own lifestyles to the lime and expense of a family.Young Americans already face a bleak labor market that cannot instill (注入) confidence about having children. Piling on higher t axes won’t help, “If higher taxes make it more expensive to raise children,” says Nicholas Eberstadt of the American Enterprise Institute, “people will thinktwice about having another child.” Tha t seems like common sense, despite the multiple influences on becoming parents.注意：此部分试题请在答题卡2上作答。

The-Science-of-Memory (1)

The Science of MemoryMemory is a fascinating and complex aspect of human cognition that has intrigued scientists, psychologists, and philosophers for centuries. The science of memory encompasses a wide range of topics, including the processes involved in encoding, storing, and retrieving information, as well as the factors that can influence the accuracy and reliability of our memories. From the study of brain structures and neural pathways to the exploration of individual and cultural differences in memory, researchers continue to uncover new insights into this fundamental aspect of human experience. One of the key areas of study within the science of memory is the process of encoding, or how information is initially learned and stored in the brain. This process involves the conversion of sensory input into a form that can be stored in memory, and it is influenced by a variety of factors, including attention, motivation, and the emotional significance of the information. For example, research has shown that people are more likely to remember emotionally charged events, such as a car accident or a wedding, than mundane, everyday occurrences. This phenomenon, known as emotional memory enhancement, highlights the powerful impact that emotions can have on the encoding process. In addition to the encoding process, the science of memory also explores the mechanisms involved in storing and retrieving information. The human brain is thought to store memories through a process of consolidation, in which new information is integrated into existing neural networks. This process is not fully understood, but it is believed to involve changes in the strength and connectivity of synapses, the junctions between neurons. Retrieval, on the other hand, involves the activation of these stored memories and their reconstruction into a conscious experience. This process can be influenced by a variety of factors, including the context in which the information was learned, the passage of time, and the presence of retrieval cues. Another important aspect of the science of memory is the study of memory errors and distortions. While we often think of memory as a reliable record of past events, research has shown that our memories can be surprisingly malleable and prone to error. For example, studies have demonstrated that people can be led to remember events that never actually occurred, simply by being exposed to misleading information. This phenomenon, known as themisinformation effect, has important implications for the reliability of eyewitness testimony and the accuracy of historical accounts. The science of memory also encompasses the study of individual and cultural differences in memory. Researchers have found that factors such as age, gender, and personality can influence various aspects of memory, including its capacity, accuracy, and susceptibility to distortion. For example, older adults often experience declinesin certain aspects of memory, such as working memory and episodic memory, while other forms of memory, such as semantic memory, may remain relatively stable. Cultural factors, such as language and education, can also shape the way people encode, store, and retrieve information, leading to differences in memory performance across different groups. In recent years, advances in technology have allowed researchers to explore the science of memory in new and exciting ways. For example, neuroimaging techniques, such as functional magnetic resonance imaging (fMRI) and electroencephalography (EEG), have provided unprecedented insights into the neural basis of memory processes. These techniques have revealed the involvement of specific brain regions, such as the hippocampus and prefrontal cortex, in different aspects of memory, shedding light on the biological underpinnings of this complex cognitive function. Overall, the science of memoryis a rich and diverse field that continues to yield new discoveries and insights into the nature of human cognition. From the study of basic memory processes tothe exploration of memory disorders and the development of memory-enhancing techniques, researchers are constantly pushing the boundaries of our understanding of memory. By shedding light on the mechanisms and limitations of memory, this research has the potential to not only deepen our understanding of the human mind, but also to inform practical applications in areas such as education, therapy, and the legal system. As our knowledge of memory continues to grow, so too will our ability to harness and utilize this fundamental aspect of human experience.。

神经系统英语作文The Nervous System: The Command Center of the Human BodyThe nervous system, often referred to as the command center of the human body, is a complex network of specialized cells that controls and coordinates all our bodily functions. This intricate system is divided into two main parts: the central nervous system (CNS) and the peripheral nervous system (PNS).The CNS consists of the brain and spinal cord. The brain is the master controller, responsible for processing information, making decisions, and initiating responses. It is also involved in memory, emotions, and consciousness. The spinal cord, on the other hand, serves as a pathway for signals to travel between the brain and the rest of the body.The PNS consists of nerves that branch out from the spinal cord to connect with various organs and tissues. These nerves are further divided into the somatic nervous system, which controls voluntary movements and sensations, and the autonomic nervous system, which regulates involuntary functions such as heart rate, blood pressure, and digestion.The nervous system works in close collaboration with other body systems, such as the endocrine system, to maintain homeostasis, the state of balance within the body. It is a highly adaptable and resilient system, capable of regenerating and reorganizing itself to some extent after injury.In conclusion, the nervous system is a vital part of the human body, essential for survival and the performance of daily activities. Its complexity and sophistication are a testament to the remarkable design of the human body.。
