2022年自考专业(英语)英语科技文选考试真题及答案37
2022年自考专业(英语)英语科技文选考试真题及答案一、阅读理解题Directions: Read through the following passages. Choose the best answer and put the letter in the bracket. (20%)1、 (A) With the recent award of the Nobel Prize in physics, the spectacular work on Bose-Einstein condensation in a dilute gas of atoms has been honored. In such a Bose-Einstein condensate, close to temperatures of absolute zero, the atoms lose their individuality and a wave-like state of matter is created that can be compared in many ways to laser light. Based on such a Bose-Einstein condensate researchers in Munich together with a colleague from the ETH Zurich have now been able to reach a new state of matter in atomic physics. In order to reach this new phase for ultracold atoms, the scientists store a Bose-Einstein condensate in a three-dimensional lattice of microscopic light traps. By increasing the strength of the lattice, the researchers are able to dramatically alter the properties of the gas of atoms and can induce a quantum phase transition from the superfluid phase of a Bose-Einsteincondensate to a Mott insulator phase. In this new state of matter it should now be possible to investigate fundamental problems of solid-state physics, quantum optics and atomic physics. For a weak optical lattice the atoms form a superfluid phase of a Bose-Einstein condensate. In this phase, each atom is spread out over the entire lattice in a wave-like manner as predicted by quantum mechanics. The gas of atoms may then move freely through the lattice. For a strong optical lattice the researchers observe a transition to an insulating phase, with an exact number of atoms at each lattice site. Now the movement of the atoms through the lattice is blocked due to therepulsive interactions between them. Some physicists have been able to show that it is possible to reversibly cross the phase transition between these two states of matter. The transition is called a quantum phase transition because it is driven by quantum fluctuations and can take place even at temperatures of absolute zero. These quantum fluctuations are a direct consequence of Heisenberg’s uncertainty relation. Normally phase transitions are driven by thermal fluctuations, which are absent at zero temperature. With their experiment, the researchers in Munich have been able to enter a new phase in the physics of ultracold atoms. In the Mott insulator state theatoms can no longer be described by the highly successful theories for Bose-Einstein condensates. Now theories are required that take into account the dominating interactions between the atoms and which are far less understood. Here the Mott insulator state may help in solving fundamental questions of strongly correlated systems, which are the basis for our understanding of superconductivity. Furthermore, the Mott insulator state opens many exciting perspectives for precision matter-wave interferometry and quantum computing.What does the passage mainly discuss?A.Bose-Einstein condensation.B.Quantum phase transitions.C.The Mott insulator state.D.Optical lattices.2、What will the scientists possibly do by reaching the new state of matter in atomic physics?A.Store a Bose-Einstein condensate in three-dimensional lattice of microscopic light traps.B.Increase the strength of the lattice.C.Alter the properties of the gas of atoms.D.Examine fundamental problems of atomic physics.3、Which of the following is NOT mentioned in relation to aweak optical lattice?A.The atoms form a superfluid phase of a Bose-Einstein condensate.B.Each atom is spread out over the entire lattice.C.The gas of atoms may move freely through the lattice.D.The superfluid phase changes into an insulating phase.4、What can be said about the quantum phase transition?A.It can take place at temperatures of absolute zero.B.It cannot take place above the temperatures of absolute zero.C.It is driven by thermal fluctuations.D.It is driven by the repulsive interactions between atoms.5、The author implies all the following about the Mott insulator state EXCEPT that______.A.the theory of Bose-Einstein condensation can’t possibly account for the atoms in the Mott insulator stateB.not much is known about the dominating interactions between the atoms in the Mott insulator stateC.it offers new approaches to exact quantum computingD.it forms a superfluid phase of a Bose-Einstein condensate6、 (B) Gene therapy and gene-based drugs are two ways we would benefit from our growing mastery of genetic science. But therewill be others as well. Here is one of the remarkable therapies on the cutting edge of genetic research that could make their way into mainstream medicine in the c oming years. While it’s true that just about every cell in the body has the instructions to make a complete human, most of those instructions are inactivated, and with good reason: the last thing you want for your brain cells is to start churning out stomach acid or your nose to turn into a kidney. The only time cells truly have the potential to turn into any and all body parts is very early in a pregnancy, when so-called stem cells haven’t begun to specialize. Most diseases involve the death of healthy cells—brain cells in Alzheimer’s, cardiac cells in heart disease, pancreatic cells in diabetes, to name a few; if doctors could isolate stem cells, then direct their growth, they might be able to furnish patients with healthy replacement tissue. It was incredibly difficult, but last fall scientists at the University of Wisconsin managed to isolate stem cells and get them to grow into neural, gut, muscle and bone cells. The process still can’t be controlled, and may have unforeseen limitations; but if efforts to understand and master stem-cell development prove successful, doctors will have a therapeutic tool of incredible power. The same applies to cloning, whichis really just the other side of the coin; true cloning, as first shown, with the sheep Dolly two years ago, involves taking a developed cell and reactivating the genome within, resenting its developmental instructions to a pristine state. Once that happens, the rejuvenated cell can develop into a full-fledged animal, genetically identical to its parent. For agriculture, in which purely physical characteristics like milk production in a cow or low fat in a hog have real market value, biological carbon copies could become routine within a few years. This past year scientists have done for mice and cows what Ian Wilmut did for Dolly, and other creatures are bound to join the cloned menagerie in the coming year. Human cloning, on the other hand, may be technically feasible but legally and emotionally more difficult. Still, one day it will happen. The ability to reset body cells to a pristine, undeveloped state could give doctors exactly the same advantages they would get from stem cells: the potential to make healthy body tissues of all sorts. And thus to cure disease.That could prove to be a true “miracle cu re”.What is the passage mainly about?A.Tomorrow’s tissue factory.B.A terrific boon to medicine.C.Human cloning.D.Genetic research.7、 According to the passage, it can be inferred that which of the following reflects the author’s opinion?A.There will inevitably be human cloning in the coming year.B.The potential to make healthy body tissues is undoubtedly a boon to human beings.C.It is illegal to clone any kind of creatures in the world.D.It is legal to clone any kind of creatures in the world except human.8、Which of the following is NOT true according to the passage?A.Nearly every cell in the human brain has the instructions to make a complete human.B.It is impossible for a cell in your nose to turn into a kidney.C.It is possible to turn out healthy replacement tissues with isolated stem cells.D.There will certainly appear some new kind of cloned animal in the near future.9、All of the following are steps involved in true cloning EXCEPT_______.A.selecting a stem cellB.taking a developed cellC.reactivating the genome within the developed cellD.resetting the developmental instructions in the cell to its original state10、The word “rejuvenated” in para. 5 is closest in meaning to_______.A.rescuedB.reactivatedC.recalledD.regulated参考答案：【一、阅读理解题】1~5CDDAD6~10DBBA。
遗传对人类健康的影响英语作文
遗传对人类健康的影响英语作文The Impact of Genetics on Human Health.Genetics, the study of heredity and the variation of inherited characteristics, plays a crucial role in determining human health. The field of genetics has made remarkable progress in recent decades, providing insights into the complex relationships between genes, environment, and disease. This essay explores the various ways in which genetics affects human health, ranging from the basic principles of inheritance to the latest advances in genetic testing and personalized medicine.At the core of genetics lies the double helix structure of DNA, the molecule that carries the genetic instructions for all known life forms. DNA contains the blueprint forour bodies, determining our physical characteristics, physiological functions, and even our susceptibility to certain diseases. The intricate dance between our genes and the environment shapes our health outcomes in numerous ways.One of the most significant impacts of genetics on human health is the inheritance of genetic diseases. Genetic diseases are caused by mutations in the DNA sequence that result in abnormal functions or structures of cells, tissues, or organs. Some genetic diseases, such as sickle cell anemia and cystic fibrosis, are caused by single gene mutations, while others, like diabetes and heart disease, are the result of complex interactions between multiple genes and environmental factors.Genetic testing has emerged as a powerful tool in the prevention, diagnosis, and treatment of genetic diseases. By analyzing a person's DNA, genetic testing can identify mutations that predispose individuals to certain diseases. This information can then be used to tailor preventive measures, such as lifestyle changes or early screenings, to reduce the risk of disease onset. In addition, genetic testing can help confirm diagnoses and guide treatment decisions, leading to more effective and personalized healthcare.Another area where genetics plays a crucial role is in the field of personalized medicine. Personalized medicine, or precision medicine, aims to tailor medical treatments to the individual characteristics of each patient. By considering a person's genetics, doctors can select drugs and therapies that are most likely to be effective and minimize side effects. This approach has the potential to revolutionize healthcare, leading to better outcomes and improved patient satisfaction.However, the influence of genetics on human health is not entirely deterministic. The environment, including our lifestyle choices, social conditions, and exposure to toxins and pathogens, also plays a significant role in determining our health outcomes. The interaction between genetics and the environment is known as epigenetics, andit represents an exciting frontier in medical research.Epigenetic studies have revealed that our environment can influence the expression of genes, sometimes even reversing the effects of genetic mutations. For example, certain lifestyle choices, such as exercise and a healthydiet, can mitigate the risk of developing diseases like heart disease and diabetes, even in individuals who carry genetic predispositions to these conditions. Conversely, exposure to stress, toxins, or other environmental factors can trigger the expression of harmful genes, leading to disease development.In conclusion, genetics plays a pivotal role in determining human health, influencing both oursusceptibility to disease and our response to medical treatments. The advances in genetic testing andpersonalized medicine have the potential to transform healthcare, allowing doctors to provide more tailored and effective treatments. However, the influence of genetics is not entirely deterministic, and the interaction between our genes and the environment remains a critical factor in determining our health outcomes. As we continue to unlock the mysteries of the genome, it is important to rememberthat our health is a complex interplay between our genetics, environment, and the choices we make every day.。

Everything alive has genes. Plants have genes.Animals have genes. You have genes. Genes are the basic units of heredity. Heredity means all the characteristics you inherit from your parents. You get your genes from your parents. You inherit half of your genes from your mother. You inherit half of your genes from your father. Genes are a kind of code. A tree’s genes tell what shape its leaves will be. A cat’s genes tell what color its fur will be. Your genes tell what color your eyes will be. Your genes tell what color your hair will be. Everything about you comes from the code in your genes. Genes line up on strands called chromosomes in cells. Everything alive is made up of cells. Chromosomes are in the center, or nucleus, of cells.An Austrian monk named Gregor Mendel first saw inherited patterns in pea plants. He experimented with pea plants in the 1860s. One of the things, or traits, Mendel studied was what makes some pea plants tall and some short. He said that the traits (特征) must come from units of heredity (遗传)passed from the parent plants. These units were called genes. In the mid-1900s, scientists discovered that genes are made of DNA. In the 1970s, scientists learned how to change DNA with genetic engineering. Scientists also learned that problems with certain genes cause diseases. Muscular dystrophy, cystic fibrosis, and hemophilia are some genetic diseases—diseases caused by problems in genes. Today, scientists are looking for ways to cure genetic diseases by altering genes through a process called gene therapy.1.

Title: The Power of Biopharmaceuticals: A Revolution in MedicineLadies and gentlemen,Good morning/afternoon/evening. Today, I stand before you to discuss a topic that has been revolutionizing the field of medicine: biopharmaceuticals. As high school students, we often hear about advancements in technology and medicine, but biopharmaceuticals stand out as a true game-changer. In this speech, I will explore the definition, history, applications, and future of biopharmaceuticals.I. IntroductionWhat are biopharmaceuticals? They are a class of therapeutic agents derived from living organisms, such as plants, animals, and microorganisms. Unlike traditional drugs, which are often synthetic or derived from chemicals, biopharmaceuticals mimic the complex interactions of the human body's own biological processes. This unique characteristic makes them highly effective in treating a wide range of diseases.II. HistoryThe concept of biopharmaceuticals dates back to the 19th century when scientists began to study the therapeutic properties of natural substances. However, it was not until the mid-20th century that the first biopharmaceutical, insulin, was produced. Since then, the field has seen rapid growth, with numerous breakthroughs in the treatment of various diseases.III. ApplicationsBiopharmaceuticals have revolutionized the treatment of many diseases, including:1. Cancer: Monoclonal antibodies, such as rituximab and trastuzumab, have become standard treatments for certain types of cancer. These antibodies target specific proteins on cancer cells, helping to eliminate them while minimizing damage to healthy cells.2. HIV/AIDS: Antiretroviral therapy (ART) has significantly improved the prognosis of HIV/AIDS patients. Biopharmaceuticals like protease inhibitors and integrase inhibitors play a crucial role in this therapy.3. Autoimmune diseases: Biopharmaceuticals such as TNF-alpha inhibitors, B-cell depleting agents, and interleukin-6 inhibitors have shown remarkable results in treating autoimmune diseases like rheumatoid arthritis and multiple sclerosis.4. Genetic disorders: Biopharmaceuticals, such as gene therapy and CRISPR technology, have the potential to cure genetic disorders by correcting the underlying genetic defects.IV. AdvantagesCompared to traditional drugs, biopharmaceuticals offer several advantages:1. High specificity: Biopharmaceuticals target specific proteins or pathways, resulting in fewer side effects and increased efficacy.2. Personalized medicine: Biopharmaceuticals can be tailored to individual patients, taking into account their genetic makeup and unique disease profiles.3. Long-term treatment: Some biopharmaceuticals, such as insulin, can be used for long-term treatment, reducing the need for frequent changes in medication.V. ChallengesDespite the numerous benefits, biopharmaceuticals also face several challenges:1. High cost: The development and production of biopharmaceuticals are expensive, making them less accessible to patients in low-income countries.2. Storage and transportation: Biopharmaceuticals often require cold chain storage and transportation, which can be challenging in resource-limited settings.3. Patents and intellectual property: The patenting of biopharmaceuticals has led to high prices and restricted access to generic versions.VI. FutureThe future of biopharmaceuticals looks promising. Ongoing research and development are expected to lead to the discovery of new therapies for a wide range of diseases. Additionally, advances in biotechnology and manufacturing processes will make biopharmaceuticals more affordable and accessible.In conclusion, biopharmaceuticals have revolutionized the field of medicine, offering new hope for patients suffering from various diseases. As high school students, it is crucial for us to understand the importance of these advancements and support further research in this field.

The potential of gene therapy Gene therapy ethics
The potential of gene therapy Genetherapy ethicsGene therapy is a promising field that has the potential to revolutionize the treatment of genetic disorders and other diseases. By introducing genetic material into a patient's cells, gene therapy has the potential to correct genetic mutations and restore normal function. However, the ethical implications of gene therapy are complex and raise important questions about safety, consent, and equity. One of the key ethical concerns surrounding gene therapy is the issue of safety. Because gene therapy involves altering a patient's genetic code, there is a risk of unintended consequences, such as triggering an immune response or causing unintended mutations. These risks raise important questions about the ethical responsibility of researchers and clinicians to ensure the safety of gene therapy treatments. Additionally, the long-term effects of gene therapy are still not fully understood, which further complicates the ethical considerations. Another ethical consideration in gene therapy is the issue of informed consent. Patients must be fully informed about the potential risks and benefits of gene therapy before they can make a decision about whether to undergo treatment. However, because gene therapy is a complex and rapidly evolving field, it can be challenging for patients to fully understand the implications of treatment. This raises important questions about how to ensure that patients are able to maketruly informed decisions about gene therapy. Equity is also a significant ethical concern in gene therapy. As with many new medical treatments, there is a risk that gene therapy could exacerbate existing health disparities. For example, if gene therapy treatments are only available to those who can afford them, it could widen the gap between the wealthy and the disadvantaged. Additionally, there is a risk that gene therapy could be used to enhance traits or abilities, leading to further inequality. Despite these ethical concerns, gene therapy also offers thepotential for tremendous benefit. For individuals with genetic disorders, gene therapy could offer the possibility of a cure or significant improvement inquality of life. In some cases, gene therapy may be the only available treatment option. This raises important questions about the ethical responsibility to pursuepotentially life-saving treatments, even in the face of uncertainty and risk. In conclusion, gene therapy holds great promise for the treatment of genetic disorders and other diseases. However, the ethical implications of gene therapy are complex and raise important questions about safety, consent, and equity. As the field of gene therapy continues to advance, it will be crucial to carefully consider these ethical concerns and ensure that the potential benefits are balanced against the potential risks. Ultimately, the ethical considerations surrounding gene therapy will play a critical role in shaping the future of this groundbreaking field.。
