我們從小學的時候起，似乎就已經(jīng)學會套用寫作模板來進行英語寫作了，不一定限定在考研才那么做。下面是學習啦小編給大家整理的考研英語沖刺范文，供大家參閱!

　　考研英語沖刺范文：Sleep

　　Sleet is part of a person's daily activity cycle. There are several different stages of sleep, and they too occur in cycles. If you are an average sleeper, your sleep cycle is as follows. When you fist drift off into slumber, your eyes will roll about a bit, you temperature will drop slightly, your muscles will relax, and your breathing well slow and become quite regular. Your brain waves slow and become quite regular. Your brain waves slow down a bit too, with the alpha rhythm of rather fast waves 1 sleep. For the next half hour or so, as you relax more and more, you will drift down through stage 2 and stage 3 sleep. The lower your stage of sleep. slower your brain waves will be. Then about 40to 69 minutes after you lose consciousness you will have reached the deepest sleep of all. Your brain will show the large slow waves that are known as the delta rhythm. This is stage 4 sleep.

　　You do not remain at this deep fourth stage all night long, but instead about 80 minutes after you fall into slumber, your brain activity level will increase again slightly. The delta rhythm will disappear, to be replaced by the activity pattern of brain waves. Your eyes will begin to dart around under your closed eyelids as if you were looking at something occurring in front of you. This period of rapid eye movement lasts for some 8 to 15 minutes and is called REM sleep. It is during REM sleep period, your body will soon relax again, your breathing will slip gently back from stage 1 to stage 4 sleep----only to rise once again to the surface of near consciousness some 80 minutes later.

　　考研英語沖刺范文：Bacteria

　　Bacteria are extremely small living things. While we measure our own sizes in inches or centimeters, bacterial size is measured in microns. One micron is a thousandth of a millimeter: a pinhead is about a millimeter across. Rod-shaped bacteria are usually from two to four microns long, while rounded ones are generally one micron in diameter. Thus if you enlarged a rounded bacterium a thousand times, it would be just about the size of a pinhead. An adult human magnified by the same amount would be over a mile(1.6 kilometer) tall.

　　Even with an ordinary microscope, you must look closely to see bacteria. Using a magnification of 100 times, one finds that bacteria are barely visible as tiny rods or dots. One cannot make out anything of their structure. Using special stains, one can see that some bacteria have attached to them wavy-looking "hairs" called flagella. Others have only one flagellum. The flagella rotate, pushing the bacteria through the water. Many bacteria lack flagella and cannot move about by their own power, while others can glide along over surfaces by some little-understood mechanism.

　　From the bacteria point of view, the world is a very different place from what it is to humans. To a bacterium water is as thick as molasses is to us. Bacteria are so small that they are influenced by the movements of the chemical molecules around them. Bacteria under the microscope, even those with no flagella, often bounce about in the water. This is because they collide with the watery molecules and are pushed this way and that. Molecules move so rapidly that within a tenth of a second the molecules around a bacteria have all been replaced by new ones; even bacteria without flagella are thus constantly exposed to a changing environment.

　　考研英語沖刺范文：Two Attitudes Toward Part-time Jobs

　　Some peolpe think there are more advantages for colleges students to take part-time jobs than disadvantages, others don't think so. What's your view on this? And tell why.

　　A serious problem has arisen in recent several years that more and more college students abandon study because of their taking part-time jobs, so quite a few people are opposed to part-time jobs. However, taking part-time jobs has at least three benefits for college studens in my eyes.

　　First, students can promote their study through part-time jobs. For instance, If a law student finds a part-time job in a law firm, his practice will enable him to better understand what he's learned from books. What's more, the part-time job can offer him opportunities to go beyond what he's been taught in class, and he'll learn something that doesn't exist in books but in practice.

　　Second, students can also accumulate work experiences through part-time jobs, which will benefit their future job-hunting. Actually, part-time jobs act as warm-up exercises for students to take full-time jobs after they graduate, and help them prepare for their future careers. In addition, as fresh blood in the society, graduated students are often unfavored in job-hunting markets for lack of practical work experiences. It's easier to find jobs for those who have accumulated experiences in part-time jobs.

　　Last but not the least, part-time jobs can partly relieve students' financial burden, especially those who are from poor families. College tution fees have greatly increased in the past ten years due to the new educational policy. Many students from poor families cannot afford college fees, and our bank system fail to loan college students as effectively as it does in developed countries, so taking part-time jobs becomes a way for them to meet their great expenses in campus lives.

　　It's an undenied fact that students break the balance between their jobs and studies, especially when they fall into conflict with each other. But I think students should spend their spare time taking part-time jobs. Only following this principle can they benefit from their part-time jobs.

　　考研英語沖刺范文：Cells and Temperature

　　Cells cannot remain alive outside certain limits of temperature and much narrower limits mark the boundaries of effective functioning. Enzyme systems of mammals and birds are most efficient only within a narrow range around 37C;a departure of a few degrees from this value seriously impairs their functioning. Even though cells can survive wider fluctuations the integrated actions of bodily systems are impaired. Other animals have a wider tolerance for changes of bodily temperature.

　　For centuries it has been recognized that mammals and birds differ from other animals in the way they regulate body temperature. Ways of characterizing the difference have become more accurate and meaningful over time, but popular terminology still reflects the old division into "warm-blooded" and "cold-blooded" species; warm-blooded included mammals and birds whereas all other creatures were considered cold-blooded. As more species were studied, it became evident that this classification was inadequate. A fence lizard or a desert iguana-each cold-blooded----usually has a body temperature only a degree or two below that of humans and so is not cold. Therefore the next distinction was made between animals that maintain a constant body temperature, called home0therms, and those whose body temperature varies with their environments, called poikilotherms. But this classification also proved inadequate, because among mammals there are many that vary their body temperatures during hibernation. Furthermore, many invertebrates that live in the depths of the ocean never experience change in the depths of the ocean never experience change in the chill of the deep water, and their body temperatures remain constant.

　　考研英語沖刺范文：一生的事業(yè)

　　As food is to the body, so is learning to the mind. Our bodies grow and muscles develop with the intake of adequate nutritious food. Likewise, we should keep learning day by day to maintain our keen mental power and expand our intellectual capacity. Constant learning supplies us with inexhaustible fuel for driving us to sharpen our power of reasoning, analysis, and judgment. Learning incessantly is the surest way to keep pace with the times in the information age, and an infallible warrant of success in times of uncertainty.

　　Once learning stops, vegetation sets in. It is a common fallacy to regard school as the only workshop for the acquisition of knowledge. On the contrary, learning should be a never-ending process, from the cradle to the grave. With the world ever changing so fast, the cease from learning for just a few days will make a person lag behind. What's worse, the animalistic instinct dormant deep in our subconsciousness will come to life, weakening our will to pursue our noble ideal, sapping our determination to sweep away obstacles to our success and strangling our desire for the refinement of our character. Lack of learning will inevitably lead to the stagnation of the mind, or even worse, its fossilization, Therefore, to stay mentally young, we have to take learning as a lifelong career.

　　學習之于心靈，就像食物之于身體一樣。攝取了適量的營養(yǎng)食物，我們的身體得以生長而肌肉得以發(fā)達。同樣地，我們應該日復一日不斷地學習以保持我們敏銳的心智能力，并擴充我們的智力容量。不斷的學習提供我們用不盡的燃料，來驅(qū)使我們磨利我們的推理、分析和判斷的能力。持續(xù)的學習是在信息時代中跟時代并駕齊驅(qū)的最穩(wěn)當?shù)姆椒?，也是在變動的世代中成功的可靠保證。

　　一旦學習停止，單調(diào)貧乏的生活就開始了。視學校為汲取知識的唯一場所是種常見的謬誤。相反地，學習應該是一種無終止的歷程，從生到死。由于世界一直快速地在變動，只要學習停頓數(shù)日就將使人落后。更糟的是，蟄伏在我們潛意識深處的獸性本能就會復活，削弱我們追求高貴理想的意志，弱化我們掃除成功障礙的決心，而且扼殺我們凈化我們?nèi)烁竦挠Ｈ鄙賹W習將不可避免地導致心靈的停滯，甚至更糟地，使其僵化。因此，為了保持心理年輕，我們必須將學習當作一生的事業(yè)。
