单选题It was not much fun to travel on one of the old sailing ships. Life was hard for both passengers and crew. 17th century sailing ships were small and rolled heavily in rough seas, so most of the passengers were seasick. There were no toilets, and the spaces below deck where passengers had to stay during gales were often not more than 5 foot high. Water was scarce and the little water they got was brown and smelt terrible. Food was a problem, too—there was only salted meat, ship"s biscuits and cheese, but the cheese was so hard that sailors often made buttons out of it for their jackets and trousers. There were no vegetables or fruit, so the people on board often fell ill. The sailors, however, were a bit better off than the passengers. They each had a bottle of beer a day, and they needed. The work they had to do was hard and dangerous. Courage was needed, for the heavy sails had to be set and taken down in all kinds of weather, and quite often sailors were swept overboard in a gale. Almost the worst thing about the voyages was the time they took up to 70 days for the journey across the Atlantic. Not surprisingly, everybody was overjoyed when they at last approached land and stepped ashore. But some ships never arrived.

单选题Normally a student must attend a certain number of courses in order to graduate, and each course which he attends gives him a credit which he may count towards a degree. In many American universities the total work for a degree consists of thirty six courses each lasting for one semester. A typical course consists of three classes per week for fifteen weeks; while attending a university a student will probably attend four or five courses during each semester. Normally a student would expect to take four years attending two semesters each year. It is possible to spread to period of work for the degree over a longer period. It is also possible for a student to move between one university and another during his degree course, though this is not in fact done as a regular practice. For every course that he follows a student is given a grade, which is recorded and available for the student to show to prospective employers. All this imposes a constant pressure and strain of work, but in spite of this some students still find time for great activity in student affairs. Elections to positions in student organizations arouse much enthusiasm. The effective work of maintaining discipline is usually performed by students who advise the academic authorities. Any student who is thought to have broken the rules, for example, by cheating, has to appear before a student court. With the enormous numbers of students, the operation of the system does involve a certain amount of activity. A student who has held one of these positions of authority is much respected and it will be of benefit to him later in his career.

单选题It was a cold winter day. A woman drove up to the Rainbow Bridge tollbooth (收费站). "I"m paying for myself, and for the six cars behind me," she said with a smile, handing over seven tickets. One after another, the next six drivers arriving at the tollbooth were informed, "Some lady up ahead already paid your fare." It turned out that the woman, Natalie Smith, had read something on a friend"s refrigerator: "Practice random kindness and senseless acts of beauty." The phrase impressed her so much that she copied it down. Judy Foreman spotted the same phrase on a warehouse wall far away from home. When it stayed on her mind for days, she gave up and drove all the way back to copy it down. "I thought it was beautiful," she said, explaining why she"d taken to writing it at the bottom of all her letters, "like a message from above." Her husband, Frank, liked the phrase so much that he put it up on the classroom wall for his students, one of whom was the daughter of Alice Johnson, a local news reporter. Alice put it in the newspaper, admitting that though she liked it, she didn"t know where it came from or what it really meant. Two days later, Alice got a call from Anne Herbert, a woman living in Maria. It was in a restaurant that Anne wrote the phrase down on a piece of paper, after turning it around in her mind for days. "Here"s the idea," Anne says. "Anything you think there should be more of, do it randomly." Her fantasies include painting the classrooms of shabby schools, leaving hot meals on kitchen tables in the poor part of town, and giving money secretly to a proud old lady. Anne says, " Kindness can build on itself as much as violence can ." The acts of random kindness spread. If you were one of those drivers who found your fare paid, who knows what you might have been inspired to do for someone else later. Like all great events, kindness begins slowly, with every single act. Let it be yours!
