脂肪是个好东西英语作文Fat is a Good ThingFat is often viewed in a negative light, associated with health problems and an unsightly appearance. However, this perception of fat is misguided and oversimplified. In reality, fat is an essential and beneficial component of the human body, serving a variety of crucial functions. While it is true that excessive fat can lead to various health concerns, a balanced and moderate amount of fat is not only necessary but also advantageous for overall well-being.One of the primary roles of fat is to provide energy for the body. Fat is a highly efficient fuel source, containing more than twice the energy content of carbohydrates and proteins. When the body's energy needs are not met through dietary intake, it turns to fat stores for the necessary fuel. This process is particularly important during periods of fasting or prolonged physical activity, when the body requires a reliable and readily available energy source. Without adequate fat reserves, the body would struggle to maintain its basic functions and would be more susceptible to fatigue and weakness.In addition to its energy-providing capabilities, fat also plays a crucialrole in the absorption and transportation of essential vitamins and minerals. Certain vitamins, such as vitamins A, D, E, and K, are fat-soluble, meaning they can only be properly absorbed and utilized by the body when accompanied by fat. By facilitating the absorption of these vital nutrients, fat helps to ensure that the body can effectively utilize the full spectrum of essential vitamins and minerals obtained through diet.Fat also serves as an important insulator for the body, helping to regulate body temperature and protect vital organs from the elements. The layer of fat beneath the skin, known as subcutaneous fat, acts as a natural barrier against the cold, preventing heat loss and maintaining a stable core body temperature. This insulating property is particularly crucial in colder climates, where the body's ability to retain heat is essential for survival and overall health.Furthermore, fat plays a crucial role in the production of hormones, which are essential for a wide range of bodily functions. Hormones such as estrogen, testosterone, and cortisol are synthesized from cholesterol, a type of fat. These hormones regulate various physiological processes, including metabolism, growth, and sexual function. Without an adequate supply of fat, the body would be unable to produce the necessary hormones, leading to hormonal imbalances and a host of related health issues.It is also important to recognize that fat serves as a valuable source of essential fatty acids, which are necessary for the proper functioning of the brain, heart, and other vital organs. Omega-3 and omega-6 fatty acids, for example, are critical for maintaining cognitive function, reducing inflammation, and supporting cardiovascular health. These essential fatty acids can only be obtained through dietary sources, and fat-rich foods are a primary means of acquiring them.While it is true that excessive fat accumulation can lead to health problems such as obesity, type 2 diabetes, and heart disease, the solution is not to completely eliminate fat from the diet. Instead, the focus should be on maintaining a balanced and healthy intake of various types of fat. This includes incorporating a variety of unsaturated fats, such as those found in nuts, avocados, and olive oil, while limiting the consumption of saturated and trans fats, which are more closely linked to negative health outcomes.In conclusion, fat is a vital and multifaceted component of the human body, serving essential functions that are crucial for overall health and well-being. From providing energy and facilitating nutrient absorption to regulating body temperature and producing hormones, fat plays a vital role in the proper functioning of the body. While it is important to be mindful of the potential risks associated with excessive fat accumulation, a balanced and moderate intake ofhealthy fats is not only beneficial but necessary for maintaining optimal physical and mental health.。
大学英语六级真题试卷Passage FourQuestions 36 to 40 are based on the following passage.Richard Satava, program manager for advanced medical technologies, has been a driving force in bringing virtual reality to medicine, where computers create a “virtual” or simulated environment for surgeons and other medical practitioners (从业者).“With virtual reality we’ll be able to put a surgeon in every trench,” said Satava. He envisaged a time when soldiers who are wounded fighting overseas are put in mobile surgical units equipped with computers.The computers would transmit images of the soldiers to surgeons back in the U.S. The surgeons would look at the soldier through virtual reality helmets (头盔) that contain a small screen displaying the image of the wound. The doctors would guide robotic instruments in the battlefield mobile surgical unit that operate on the soldier.Although Satava’s vision may be years away from standard operating procedure, scientists are progressing toward virtual reality surgery. Engineers at an international organization in California are developing a tele-operating device. As surgeons watch a three-dimensional image of the surgery, they move instruments that are connected to a computer, which passes their movements to robotic instruments that perform the surgery. The computer provides feedback to the surgeon on force, textures, and sound.These technological wonders may not yet be part of the community hospital setting but increasingly some of the machinery is finding its way into civilian medicine. At Wayne State University Medical School, surgeon Lucia Zamorano takes images of the brain from computerized scans and uses a computer program to produce a 3-D image. She can then maneuver the 3-D image on the computer screen to map the shortest, least invasive surgical path to the tumor (肿瘤). Zamorano is also using technology that attaches a probe to surgical instruments so that she can track their positions. While cutting away a tumor deep in the brain, she watches the movement of her surgical tools in a computer graphics image of the patient’s brain taken before surgery. During these procedures—operations that are done through small cuts in the body in which a miniature camera and surgical tools are maneuvered—surgeons are wearing 3-D glasses for a better view. And they are commanding robot surgeons to cut away tissue more accurately than human surgeons can.Satava says, “We are in the midst of a fundamental change in the field of medicine.”36. According to Richard Satava, the application of virtual reality to medicine ________.A) will enable surgeons to be physically present on every battlefieldB) can raise the spirits of soldiers wounded on the battlefieldC) will greatly improve medical conditions on the battlefieldD) can shorten the time for operations on soldiers wounded on the battlefield37. Richard Satava has visions of ________.A) using a remote-control technique to treat wounded soldiers fighting overseasB) wounded soldiers being saved by doctors wearing virtual reality helmets on the battlefieldC) wounded soldiers being operated on by specially trained surgeonsD) setting up mobile surgical units overseas38. How is virtual reality surgery performed?A) It is performed by a computer-designed high precision device.B) Surgeons wear virtual reality helmets to receive feedback provided by a computer.C) Surgeons move robotic instruments by means of a computer linked to them.D) A 3-D image records the movements of the surgeons during the operation.39. During virtual reality operations, the surgeon can have a better view of the cuts in the body because ________.A) he is looking at the cuts on a computer screenB) the cuts can be examined from different anglesC) the cuts have been highly magnifiedD) he is wearing 3-D glasses40.

Ever since then, forecasters have being warning that worldwide famine was (S1) just around the next corner. The fast-growing population’s demand for food, they warned, would soon exceed their (S2) supply, leading to widespread food shortages and starvation.But in reality, the world’s total grain harvest has risen steadily over the years. Except for relative isolated trouble (S3) spots like present-day Somalia, and occasional years of good harvests, the world’s food crisis has remained just (S4) around the corner. Most experts believe this can continue even as if the population doubles by the mid-21st century, (S5) although feeding 10 billion people will not be easy for politics, economic and environmental reasons. Optimists (S6) point to concrete examples of continued improvements in yield. In Africa, by instance, improved seed, more (S7) fertilizer and advanced growing practices have more than double corn and wheat yields in an experiment. Elsewhere, (S8) rice experts in the Philippines are producing a plant with few (S9) stems and more seeds. There is no guarantee that plant breeders can continue to develop new,higher-yielding crop, but most researchers see their success to date as reason (S10) for hope.Part V Writing (30 minutes)Directions:In this section you are required to write a composition on the topic Reduce Waste on Campus.

6月大学英语四级阅读模拟试题二2015年6月大学英语四级阅读模拟试题(二)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.Fried foods have long been frowned upon. Nevertheless, the skillet (长柄平底煎锅) is about our handiest and most useful piece of kitchen equipment. Strong woodcutters and others engaged in active labor requiring 4,000calories per day or more will take approximately one-third of their rations prepared in this fashion. Meat, eggs, and French toast cooked in this way are served in millions of homes daily. Apparently the consumers are not beset with more signs of indigestion than afflicted by those who insist upon broiling, roasting, or boiling. Some years ago one of our most eminent physiologists investigated the digestibility of fried potatoes. He found that the pan variety was more easily broken down for assimilation than when deep fat was employed. The latter, however, dissolved within the alimentary tract ( 消化道) more readily than the boiled type. Furthermore, he learned, by watching the progress of the contents of the stomach by means of the fluoroscope (荧光检查仪), that fat actually accelerated the rate of digestion. Now all this is quite in contrast with "authority". Volumes have been written on nutrition, and everywhere the dictum ( 权威意见) has been accepted--no fried edibles of anysort for children. A few will go so tar as to forbid this style of cooking wholly. Now and then an expert will be bold enough to admit that he uses them himself, the absence of discomfort being explained on the ground that he possesses a powerful gastric ( 胃的 )apparatus. We can of course sizzle perfectly good articles to death so that they will be leathery and tough. But thorough heating, in the presence of shortening, is not the awful crime that it has been labeled. Such dishes stimulate rather than retard contractions of the gall bladder. Thus it is that bile ( 胆汁 ) mixes with the nutriment shortly after it leaves the stomach.We don't need to allow our foodstuffs to become oil soaked, but other than that, there seems to be no basis for the widely heralded prohibition against this method. But notions become fixed. The first condemnation probably rose because an "oracle" ( 圣贤) suffered from dyspepsia (消化不良) which he ascribed to some fried item on the menu. The theory spread. Others agreed with him, and after a time the doctrine became incorporated in our textbooks. The belief is now tradition rather than proved fact. It should have been refuted long since, as experience has demonstrated its falsity.56. This passage focuses on__________.A. why the skillet is a handy piece of kitchen equipmentB. the digestibility of fried foodsC. how the experts can mislead the public in the area of food preparationD. why fried foods have long been frowned upon57. People engaged in active labor eat fried foods because __________.A. they are healthfulB. they are much cheaperC. they can be easily digestedD. they can provide the calories the workers need58. The author implies that the public should__________.A. prepare some foods by fryingB. avoid fried foods if possibleC. fry foods for adults but not for childrenD. prepare all foods by frying59. When the author says that "an 'oracle' suffered from dyspepsia which he ascribed to some fried item on the menu" he is being__________.A. gratefulB. factualC. sarcasticD. humorous60. The passage was probably taken from__________.A. a medical journalB. a publication addressed to the general publicC. a speech at a medical conventionD. an advertisement for cooking oil【参考译文】很长时间以来,人们都不喜欢油炸食品。

NoticeDear students,Attention, please. _____________________________________________________________ ________________________________________________________________________________ ________________________________________________________________________________ That’s all.Thank you.Students’ Union 参考范文:NoticeDear_students,Attention,_please. In order to broaden students’ horizon, the Students’ Union will hold a lecture in the science festival, introducing the great scientist Tu Youyou as well as her achievements. The lecture will be given in the new-built gymnasium from 9:00 a.m. to 11:00 a.m. on Monday, September 24.Born in Ningbo, Zhejiang Province in 1930, Tu Youyou was admitted into Peking University Health Science Center in 1951,and she graduated in 1955. Together with her colleagues, Tu found artemisinin, an effective cure for malaria. Due to making such a great contribution to the world, she was awarded with the 2015 Nobel Prize in Medicine, becoming the first Chinese scientist who got the prize.Anyone who is interested in knowing more about the great scientist is welcome to attend the lecture.That’s_all.Thank_you.Students’_Union2.阅读理解A(2022·湖北省八市联考) Most Chinese know the story of the mythological Chang’e,the Chinese goddess of the moon. It’s a story about a woman who takes an immortality pill and flies to the moon. It is told every year during China’s Mid-Autumn Festival, so people can’t hear the word “Change” without thinking of romantic images of a moon goddess.For this reason, China’s mission to the moon was calling out for a strong female figure. Therefore, pictures of a 24-year-old female space commander have gone viral on Chinese social media for her work on the Chang’e-5 lunar exploration program with comments about how she is a “frontline soldier in the field of aerospace” that young Chinese can look up to.Ms. Zhou, a 24-year-old lady of Tujia ethnic group, is China’s youngest ever space commander. She was involved in the successful launch of the Chang’e-5 lunar probe on 24 November, in charge of the rocket connector system, described as a key role.In Wenchang space launch site, though she is only 1.58 meters and looks “mini”,she is called “big sister” for her powerful “core and energy”.Since senior high, she has dreamed of being a member of a space research team. With her great efforts, she was admitted to an aircraft system and engineering major of a domestic university in 2014, making her aerospace dream come true. To grow into a commander, in two and a half years, she changed five positions to be familiar with multiple posts and types of work, each of which takes great courage and is full of challenges. In a working space with no air conditioning and narrow space to accommodate only three people, she worked for 60 days until the completion of the “Long March 5 rocket goes around” battle.Her story has received attention from Chinese state-run media as well as overseas media outlets. However, it has not appeared to have much of an effect on her. According to the media, she declined repeated requests for interviews as she does not wish to let fame get in the way of her work.语篇解读:本文是一篇记叙文。
