40、ed me how much practicing I was doing, I said three or four hours a day.“Do you practice in long stretches, an hour at a time?”“I try to.”“Well, dont.” he shouted. When you grow up, time wont come in long stretches. Practice in minutes, whenever you can find them, five or ten before school, after lu

41、nch, between household tasks. Spread the practice through the day, and the violin playing will become a part of your life.”When I was teaching at Boston, I wanted to write a novel, but class periods, theme-reading, and committee meetings filled my days and evenings. For two years I got practically n

42、othing down on paper, and my excuse was that I had no time. Then I remembered what Sam had said. During the next week I conducted an experiment. Whenever I had five minutes unoccupied, I sat down and wrote a hundred words or so. To my surprise, at the end of the week I had finished a chapter. Later

43、on I continued my novels by the same piecemeal period. Though my teaching schedule had become heavier than ever, every day there were unoccupied moments that could be caught and put to use. I even took up violin-playing again, finding that the short moments of the day provided sufficient time for bo

44、th writing and violin practice.There is an important trick in this time-using formula(方案): you must get into your work quickly. If you have but five minutes for writing, you cant afford to waste for chewing your pencil. You must make your mental preparations beforehand, and concentrate on your task

45、almost instantly when the time comes. Fortunately, rapid concentration is easier than most of us realize.I admit I have never learnt how to let it go easily at the end of the five or ten minutes. But life can be counted on to supply interruptions. Sam Traffton has had a great influence on my life. T

49、e because his teaching schedule is always heavy59.What is the best title for this passage?A. A Little Time at a TimeB. How I Became a WriterC. Concentrate on Your WorkD. A Good Teacher(B)In ancient Egypt, the pharaoh(法老)treated the poor message runner like a prince when he arrived at the palace, if

50、he brought good news. However, if the exhausted(精疲力竭的) runner had the misfortune to bring the pharaoh unhappy news, his head was cut offShades of that spirit spread over todays conversations. Once a friend and I packed up some peanut, butter and sandwiches for an outing. As we walked light-heartedly

51、 out the door, picnic basket in hand, a smiling neighbor looked up at the sky and said, “Oh boy, bad day for a picnic. The weatherman says its going to rain.” I wanted to strike him in the face with the peanut butter and sandwiches. Not for his stupid weather report, but for his smile.Several months

52、 ago I was racing to catch a bus. As I breathlessly put my handful of cash across the Greyhound counter, the sales agent said with a broad smile. “Oh that bus left five minutes ago.” Dreams of head cutting!Its not the news that makes someone angry. Its the unsympathetic attitude with which its deliv

53、ered. Everyone must give bad news from time to time, and winning professionals do it with the proper attitude. A doctor advising a patient that she needs an operation does it in a caring way. A boss informing an employee he didnt get the job takes on a sympathetic tone. Big winners know, when delive

54、ring any bad news, they should share the feeling of the receiver. Unfortunately, many people are not aware of this. When youre tired from a long flight, has a hotel clerk cheerfully said that your room isnt ready yet? When you had your heart set on the toast beef, has your waiter merrily told you th

55、at he just served the last piece? It makes you, as traveler or diner, want to land your fist fight on their unsympathetic faces. Had my neighbor told me of the upcoming rainstorm with sympathy, I would have appreciated his warning. Had the Greyhound salesclerk sympathetically informed me that my bus

56、 had already left, I probably would have said, “Oh, thats all right. Ill catch the next one.” Big winners, when they hear bad news, deliver bombs with the emotion the bombarded (被轰炸的) person is sure to have .60.In Paragraph 1, the writer tells the story of the pharaoh to .A. make a comparisonB. intr

A. Delivering bad news properly is important in communication. B. Helping others sincerely is the key to

58、 business success. C. Receiving bad news requires great courage.D. Learning ancient traditions can be useful.(C)Have you winterized your horse yet? Even though global warming may have made our climate, more mild, many animals are still hibernating(冬眠). Its too bad that humans cant hibernate. In fact

59、, as a species, we almost did.Apparently, at times in the past, peasants in France liked a semi-state of human hibernation. So writes Graham Robb, a British scholar who has studied the sleeping habits of the French peasants. As soon as the weather turned cold, people all over the France shut themsel

60、ves away and practiced the forgotten art of doing nothing at all for months on end. In line with this, Jeff Warren, a producer at CBC Radios The Current, tells us that the way we sleep has changed fundamentally since the invention of artificial lighting and the electric bulb.When historians began st

61、udying texts of the Middle Ages, they noticed something referred to as “first sleep”, which was not clarified, though. Now scientists are telling us our ancestors most likely slept in separate periods. The business of eight hours uninterrupted sleep is a modem invention.In the past, without the arti

62、ficial light of the city to bathe in, humans went to sleep when it became dark and then woke themselves around midnight. The late night period was known as “The Watch”. It was when people actually kept watch against wild animals, although many of them simply moved around or visited family and neighb

63、ors.According to some sleep researchers, a short of insomnia(失眠)at midnight is not a disorder. It is normal. Humans can experience another state of consciousness around their sleeping, which occurs in the brief period before we fall asleep or wake ourselves in the morning. This period can be an extr

64、aordinarily creative time for some people. The impressive inventor, Thomas Edison, used this state to hit upon many of his new ideas.Playing with your sleep rhythms can be adventurous, as anxiety may set in. Medical science doesnt help much in this case. It offers us medicines for a full nights cont

65、inuous sleep, which sounds natural; however, according to Warrens theory, it is really the opposite of what we need.63.The example of the French peasants shows the fact that .A. people might become lazy as a result of too much sleepB. there were signs of hibernation in human sleeping habitsC. people

66、 tended to sleep more. Peacefully in cold weatherD. winter was a season for people to sleep for months on end 来源: 64.What does the author advise people to do? A. Sleep in the way animals do.B.

The advantage of using Loot is that there are some excellent bargains. The disadvantage is that there is no quality control over the offers. Rentin

71、g is another useful paper. The offers in this paper are mainly from accommodation agencies.

The advantage of using accommodation agencies

72、 is that: you will have access to a large number of accommodations. A good agent will listen to your requirements and can save you time in looking for the right accommodation.

Some universities will also have online notice boards where students can advertise to other students. Advertisements from students can be an excellent way to find acc

Word of mouthSome of the best housing in London is never advertised but is passed on from one group of students to another by word of mouth. It might be that you can find out about good offers from final year students. However, d

Hess is the director of education policy studies at the American Enterprise Institute, which is a nonprofit organization that conducts research on many public issues. He says that a long summer vacation doesnt make sense in todays world.

80、 Can American students afford to take a summer vacation? In a summer vacation, millions of kids spend valuable time sending messages, watching TV, playing video games and doing shopping in the mall. They will also be putting their academic futures at risk. Summer vacation once made sense in the past

81、 when you didnt need an education to get a good job. But now things have changed. For todays students, academic skills are important to students future success, but such skills are affected in the summertime. Many nations dont give kids an American-style summer vacation. They offer no more than seve

82、n consecutive(连续的) weeks of vacation. Most American school districts offer up to thirteen weeks. To compete in the global marketplace, Americans must be prepared to go up against international competitors. Summer vacation also causes challenges for todays families. In the 1960s, more than 60% of fam

83、ilies had a stay-at-home Mom. Now two-thirds of American children live in households where every adult works. For these families, summer vacation can be more burden than break. Someone must watch the kids. But the biggest problem may be how summer vacation hurts academic achievement. Researchers hav

84、e found that disadvantaged students lose significant ground in the summertime. A longer school year does not have to be an invitation to hard boring work. Rather, it should allow time-pressed teachers to conduct richer and more imaginative lessons. Schools should have more time to devote to athletic

85、s, languages, music and the arts. Summer vacation can be a grand thing. But in the 21st century, it may also be outdated.
