Children who grip their pens too close to the writing point are likely to be at a disadvantage in examinations, (31) to the first serious investigation into the way in which writing technique can dramatically affect educational achievement.The survey of 643 children and adults, ranking from pre-school to 40-plus, also suggests (32) pen-holding techniques have deteriorated sharply over one generation, with teachers now paying far (33) attention to correct pen grip and handwriting style.Stephanie Thomas, a learning support teacher (34) findings have been published, was inspired to investigate this area (35) he noticed that those students who had the most trouble with spelling (36) had a poor pen grip. While Mr. Thomas could not establish a significant statistical link (37) pen-holding style and accuracy in spelling, he (38) find huge differences in technique between the young children and the mature adults, and a definite (39) between near-point gripping and slow, illegible writing.People who (40) their pens at the writing point also show other characteristics (41) inhibit learning, (42) as poor posture, leaning too (43) to the desk, using four fingers to grip the pen (44) than three, and clumsy positioning of the thumb (which can obscure (45) is being written).Mr. Thomas believes that the (46) between elder and younger writers is (47) too dramatic to be accounted for simply by the possibility that people get better at writing as they grow (48) . He attributes it to a failure to teach the most effective methods, pointing out that the differences between (49) groups coincides with the abandonment of formal handwriting instruction in classrooms in the sixties. "The 30-year-old showed a huge diversity of grips, (50) the over 40s group all had a uniform ’tripod’ grip. \ 49().

Does the publisher of Douglas Starr’s excellent Blood—An Epic History of Medicine and Commerce actually expect to sell many copies Whoever chose the title is certain to scare off the squeamish, and the subtitle, which makes the effort sound like a dry, dense survey text, has really done this book a disservice. In fact, the brave and curious will enjoy a brightly written, intriguing, and disquieting book, with some important lessons for public health.66. ______The book begins with a historical view on centuries of lore about blood—in particular, the belief that blood carried the evil humors of disease and required occasional draining. As recently as the Revolutionary War, Bloodletting was widely applied to treat fevers. The idea of using one person’s blood to heal another is only about 75 years old although rogue scientists had experimented with transfusing animal blood at least as early as the 1600s. The first transfusion experiments involved stitching a donor’s vein (in early cases the physician’s) to a patient’s vein.67. ______Sabotaged by notions about the" purity" of their groups’ blood, Japan and Germany lagged well behind the Allies in transfusion science. Once they realized they were losing injured troops the Allies had learned to save, they tried to catch up, conducting horrible and unproductive experiments such as draining blood from POWs and injecting them with horse blood or polymers.68. ______During the early to mid-1980s, Start says, 10,000 American hemophiliacs and 12,000 others contracted HIV from transfusions and receipt of blood products. Blood banks both here and abroad moved slowly to acknowledge the threat of the virus and in some cases even acted with criminal negligence, allowing the distribution of blood they knew was tainted. This is not new material. But Starr’s insights add a dimension to a story first explored in the late Randy Shilts’s And the Bond Played On.69. ______Is the blood supply safe now Screening procedures and technology have gotten much more advanced. Yet it’s disturbing to read Starr’s contention that a person receiving multiple transfusions today has about a 1 in 90,000 chance of contracting HIV—far higher than the" one in a million" figure that blood bankers once blithely and falsely quoted. Moreover, new pathogens threaten to emerge and spread through the increasingly high-speed, global blood-product network faster than science can stop them. This prompts Starr to argue that today’s blood stores are" simultaneously safer and more threatening" than when distribution was less sophisticated.70. ______A. The massive wartime blood drives laid the groundwork for modern blood-banking, which has saved countless lives. Unfortunately, these developments also set the stage for a great modern tragedy—the spread of AIDS through the international blood supply.B. There is so much drama, power, resonance, and important information in this book that it would be a shame if the squeamish were scared off. Perhaps the key lesson is this: The public health must always be guarded against the pressures and pitfalls of competitive markets and human fallibility.C. In his chronicle of a resource, Starr covers an enormous amount of ground. He gives us an account of mankind’s attitudes over a 400-year period towards this "precious, mysterious, and hazardous material" ; of medicine’s efforts to understand, control, and develop blood’s life-saving properties; and of the multibillion-dollar industry that benefits from it. He describes disparate institutions that use blood, from the military and the pharmaceutical industry to blood banks. The culmination is a rich examination of how something as horrifying as distributing blood tainted with the HIV virus could have occurred.D. The book’s most interesting section considers the huge strides transfusion science took during World War Ⅱ. Medicine benefited significantly from the initiative to collect and supply blood to the Allied troops and from new trauma procedures developed to administer it. It was then that scientists learned to separate blood into useful elements, such as freeze-dried plasma and clotting factors, paving the way for both battlefield miracles and dramatic improvement in the lives of hemophiliacs.E. Starr’s tale ends with a warning about the safety of today’s blood supply.F. Start obtained memos and other evidence used in Japanese, French, and Canadian criminal trials over the tainted-blood distribution. (American blood banks enjoyed legal protections that made U.S. trials more complex and provided less closure for those harmed.) His account of the French situation is particularly poignant. Starr explains that in postwar France, donating blood was viewed as a sacred and patriotic act. Prison populations were urged to give blood as a way to connect more with society. Unfortunately, the French came to believe that such benevolence somehow offered a magical protection to the blood itself and that it would be unseemly to question volunteer donors about their medical history or sexual or drug practices. Combined with other factors, including greed and hubris, this led to tragedy. Some blood banks were collecting blood from high-risk groups as late as 1990, well into the crisis. And France, along with Canada, Japan, and even Britain, stalled approval and distribution of safer, American heat-treated plasma products when they became available, in part because they were giving their domestic companies time to catch up with scientific advances. 67().
Questions 17～20 are based on the following talk. You now have 20 seconds to read Questions 17～20.The human nose has given to the languages of the world many interesting expressions. Of course, this is not surprising. Without the nose, we could not breathe nor smell. It is a part of the face that gives a person special character. Cyrano de Bergerac said that a large nose showed a great man courageous, courteous, manly, and intellectual.A famous woman poet wished that she had two noses to smell a rose! Blaise Pascal, a French philosopher, made an interesting comment about Cleopatra’s nose. If it had been shorter, he said, it would have changed the whole face of the world!Historically, man’s nose has had a principal role in his imagination. Man has referred to the nose in many ways to express his emotions. Expressions concerning the nose refer to human weakness: anger, pride, jealousy and revenge.In English there are a number of phrases about the nose. For example, to hold up one’s nose expresses a basic human feeling—pride. People can hold up their noses at people, things, and places.The phrase, to be led around by the nose, shows man’s weakness. A person who is led around by the nose lets other people control him. On the other hand, a person who follows his nose lets his instinct guide him.For the human emotion of rejection, the phrase to have one’s nose put out of joint is very descriptive. The expression applies to persons who have been turned aside because of a rival. Their pride is hurt and they feel rejected. This expression is not new. It was used by Erasmus in 1542.This is only a sampling of expressions in English dealing with the nose. There are a number of others. However, it should be as plain as the nose on your face that the nose is more than an organ for breathing and smelling! What is this passage mainly about().
Every year there are reports of people dying as the result of extremely hot weather. Many of the victims are old persons, whose hearts or breathing systems decline. But many die from lack of water.Water is necessary for life and good health. We often forget this fact when we think about the other building blocks of life such as vitamins, minerals and proteins. We can live for many days without eating, but two or three days without water usually leads to death.The human body may look solid, but most of it is water. New born babies are as much as 85% water. Women are about 65% water and men about 75%. Women usually have less water than men because women, in general, have more fat cells, and fat cells hold less water than other kinds of cells.Water does many different things to keep us healthy. It carries hormones, antibodies and foods through the body, and carries away waste materials. That is why different parts of the body contain different amounts of water. For example, blood is 83% water, muscles are 75% water, the brain is 74%, and bones are 25%.Water is also necessary for cooling the body under hot weather and when we are working hard or exercising, water carries body heat tO the surface of the skin, where the heat is lost through perspiration. Researchers say cool liquids cool us faster than warm liquids, because cold liquids take up more heat inside the body and carry it away faster. They say, however, that cold sweet drinks do not work well because the sugar slows the liquid from getting into the blood-stream.Researchers also note that fat ceils block body heat from escaping quickly. Fat cells under the skin act like warm clothing to keep body heat inside. This is why overweight people have a more easy time staying cool than thin people.The body loses water every day through perspiration and urine. If we lose too much, we will become sick. A 10% drop in body water can cause the blood system to fail. A 15%～20% drop usually leads to death. To replace what is lost, health experts say growing persons should drink about 2 liters of liquids each day, and more in hot weather. They say we can also get some of the water we need in the foods we eat. Most fruits and vegetables are more than 80% water. Meats are 50%-60% water. And even bread is about 33% water. Water may be one of the most simple of all chemical substances, but it is the most important substance that we put into our bodies. Health experts say that all kinds of people should drink at least about 2 liters of liquids every day.
Last time we started looking at the question of management and wondering what the term actually meant. Then we took a brief look at the concept of scientific management. You remember, we decided it was useful but not enough on its own. So today we’re going to look at another aspect—behavioral management. You may not really have come across this word "behavioral" before, though I’m sure you are familiar with the word "behavior". Behavioral simply means having to do with behavior. And that is our starting point for today: We are going to start by realizing that the activity of any organization is human activity, designed to achieve human goals. So we are really talking about human behavior.Any business concern does two things. First, it provides either goods or services that the customer needs. That is, it either makes things or does things for other people in exchange for money. Second, it provides people with work—and most of us have to work in order to make a living.Work, much as we may sometimes wish we didn’t have to do it, or not quite so much of it, has in fact two advantages. First—and I spoke about this last time—it can give us satisfaction. We can be proud of what we are doing—like a craftsman making something beautiful, or a doctor of a nurse helping people who are ill or in pain. This is what I called job satisfaction, and without it I am sure work can become an awful burden. And on a more basic level, work earns us money, which we can use to buy the things we need in order to live, like food and somewhere to live, as well as all the luxuries we could probably do without but still like to have.Behavioral management is based on a research of how people behave at work. It uses the findings of psychologists and sociologists, and so on. These make a study of individuals and groups to see what things influence the way they behave in different conditions. The results can then be used to design the best conditions in which people will perform—or behave—in the way that a manager wants them to in order to make a business more efficient and to achieve its goals. They have collected a lot of evidence and formulated a lot of theories to help the manager, and there is no doubt that properly understood and applied, this can be very useful.But still we return to the fact that people are individuals, all different from each other, and all—as we say—with minds of their own. So no matter what the manager knows about the way people behave in groups and so on, he has really to treat everyone on his staff as an individual in his own right. Of course, he can be helped in this by knowing how to encourage people to do things, how to stimulate them to behave in a certain way, and so on. A manager can himself be taught how to do this, but however unscientific this may sound, it is more likely that a good manager is born rather than trained. He has some natural ability to recognize what people are likely to do, what abilities they have, and other things like that. Realizing this, and then applying what he has learned about human behavior, is what makes someone a good manager.So behavioral management is management based on an assessment of an individual and the application of what is known about how people in general tend to behave. Like scientific management, it is undoubtedly useful, but not, the complete answer. What does the speaker refer the activity of any organization to
