高三英语未来科技练习题30题
高三英语未来科技练习题30题1<背景文章>Artificial intelligence (AI) is rapidly transforming the field of healthcare. In the medical field, AI has shown great potential in various aspects. One of the significant applications of AI is in disease diagnosis. By analyzing large amounts of medical data, including patient symptoms, medical images, and lab results, AI algorithms can accurately diagnose diseases at an early stage. This not only helps in timely treatment but also improves the chances of recovery.Another area where AI is making a significant impact is in drug discovery. AI can analyze vast amounts of biological and chemical data to identify potential drug candidates more quickly and efficiently than traditional methods. This can lead to the development of new drugs in a shorter time frame.However, the application of AI in healthcare also faces some challenges. One of the main challenges is data privacy and security. Medical data is highly sensitive, and ensuring its protection is crucial. Another challenge is the lack of standardization in medical data, which makes it difficult for AI algorithms to learn and generalize. Additionally, there is a need for regulatory frameworks to ensure the safe and ethical useof AI in healthcare.1. What is one of the significant applications of AI in the medical field?A. Medical education.B. Disease diagnosis.C. Hospital management.D. Nursing care.答案：B。

Directions: Complete the sentences with the words given in the brackets.

(base)2) Indeed, this separation of meaning is reflected by the definition of "weak" in the OALD, with adistinct sense reserved for its use when pertaining to that of solutions (definition)3) The resulting radical pollution control programme outlined by Nixon, calling for a 90 per centreduction in vehicle emissions by 1980, not only led to him being credited (albeit briefly) as policy initiator of an environmental clean-up but also provided him with the chance to deal a blow to one of his most important opponents in the 1972 elections, Edmund Muskie (blow)4) Singapore's continuing investments in education and training has brought a tenfold increase in ourpool of Information Technology professionals and the Singapore worker has been consistently rated by BERI as the world's best in terms of technical skills, attitude and productivity.

Join the following short sentences into longer ones.1) In addition to coining the term "fractal" to describe objects and surfaces which are irregular atvarious dimensions of scale, he also introduced such concepts as "fractal dimensions" and the particular fractal known as the Mandelbrot set, frequently represented with the mathematical formula z → z2 + c.2) It appeared that things were settling into a pleasant and fruitful routine, with hi s school lessonssupplemented by long talks with his uncle about classical analysis, the iterative work of Pierre Fatou and the equally fascinating Julia Sets generated by Gaston Julia3) Just as the youthful Mandelbrot had passed his college entrance exams by translating algebraicproblems into geometrical problems, and solving them by intuitively deducing the "perfected"shape, he here realized there was something deeper, something mathematical, be hind these strange patterns.4) But the beauty in Mandelbrot's models was not that they generated a deceitful randomness, butthat they could generate graphed data whose visual pattern accurately mimicked the visual patterns created by real phenomena。

科技英语翻译期末练习题
科技英语翻译大作业(科技英语6&13班)I.全篇翻译passage1：Passage１Billing for goods and services that customers have purchased is part of any business. Traditional billing methods in the brick-and-mortar paradigms are costly and involve generating invoices, stuffing envelopes, affixing proper postage to the envelopes, and sending the invoices to the customers. Meanwhile, the accounts payable department must keep track of incoming payments, post accounts in the database, and ensure that customer data are current.Online stores have many of the same payment collection inefficiencies as their brick-and-mortar cousins. Most online customers use credit cards to pay for their purchases, while auction customers may also use conventional payments methods, including checks and money orders. Electronic cash systems, though less popular than other payment methods do provide several advantages as well as some disadvantages unique to electronic cash.For the most part, electronic cash transactions aremore efficient (and therefore less costly) than other methods, and that should foster more business, which eventually means lower prices for consumers. Transferring electronic cash on the Internet costs less than processing credit card transactions. You have observed that conventional money exchange systems require banks, banks branches, clerks, automated teller machines, and a parallel electronic transaction system to manage, transfer and dispense cash. That is expensive. On the other hand, electronic cash transfers occur across an existing infrastructure, the Internet, and through existing computer systems. So the fixed cost of hardware to handle electronic cash is nearly zero. Because the Internet spans the globe, the distance that an electronic transaction must travel does not affect cost. When considering moving physical cash and checks, distance and cost are proportional---the greater the distance that the currency has to go, the more it costs to move it. However, moving electronic currency from Detroit to San Francisco costs the same as moving it from San Francisco to Hong Dong. Everyone can use electronic cash. Merchants can pay other merchants ina business-to-business relationship, and consumers can pay each other. Electronic cash does not require that one party have any special authorization, as is required with credit card transactions. (345 words)II.请翻译passage 2中带有下划的5个句子：Passage２1) Anxiety may be the most common mental disorder experienced by older adults, affecting one in 10 people over the age of 60, according to research presented at the Annual Meeting of the American Psychiatric Association in Toronto. Despite its prevalence, anxiety remains one of the most undiagnosed and undertreated conditions in this population.Examples of anxiety disorders include panic disorder, obsessive compulsive disorder, phobias and generalized anxiety disorder (GAD). GAD is characterized by exaggerated, uncontrollable worries about everyday things. 2) While many worrisome events occur as people age and while it is normal for people to be concerned about such things as deteriorating health and financial troubles, people with GAD tend to worry excessivelyand constantly.3) “Studies have shown that generalized anxiety disorder is more common in the elderly, affecting seven per cent of seniors, than depression, which affects about three per cent of seniors. Surprisingly, there is little research that has been done on this disorder in the elderly,” said Eric J. Lenze, M.D., assistant professor of psychiatry, University of Pittsburgh School of Medic ine. “Doctors often think that this disorder is rare in the elderly or that it is a normal part of aging, so they don’t diagnose or treat anxiety in their older patients, when, in fact, anxiety is quite common in the elderly and can have a serious impact o n quality of life.”This constant level of worry can have negative, and sometimes even disabling, effects on a person’s life. Many people with GAD have trouble sleeping or limit their daily activities due to their anxiety. 4) Untreated anxiety can also lead to anxious depression – a condition that is more difficult to treat and carries a higher risk of suicide than depression.“Anxiety in people over age 60 might has some similarities to anxiety in those younger, but it also hasmarked differences. We ca n’t just assume that we can treat the two age groups the same,” said Dr. Lenze. 5) “We are decades behind where we need to be in terms of research and treatments for anxiety in this older age group.” There are, however, encouraging signs that studies are beginning to address treatment options. What It Means: Anxious older adults and their families should be aware of the prevalence of anxiety disorders. Excessive fretting should not be considered an inevitable sign of aging. A small pilot study conducted at the University of Pittsburgh has shown that ananti-depressant drug was also effective in treating anxiety in older adults. Additional studies hope to address the role of cognitive behavioral therapy or other therapies for anxiety in the elderly. There are indeed enough things to worry about when growing older. But uncontrollable, excessive worry shouldn’t be among them. (453 words)。
