An Awful Afternoon
Sometimes I feel that being the mother of three small children is like running a large circus(马戏团). One afternoon last week, my three sons were playing peacefully in the backyard, throwing the ball from one to the other. I jumped at the chance to talk to one of my friends on the phone, but before I got to the phone, I could tell that the boys had begun to quarrel with each other over something. I rushed out to make peace, but before I got there, Charles had begun to fight over this. Even David, the oldest boy, who won’t usually fight with anybody over anything, was involved. First, I made them stop fighting, and then I examined Mark’s eye. I decided that it wasn’t going to develop into a black eye, but I felt that they should suffer at least a little for what they had done.

[单项选择]Jonathan Rivers lived alone in a neat house in Compton Street and worked in London. Like many other single men in their middle age, he was getting rather set in his ways. He looked after the house well and had a beautiful garden. Before he left the house in the morning, he would carefully close all the doors downstairs, open some windows upstairs to let the air in and lock the front door.

[单项选择]According to a survey, which was based on the responses of over 188,000 students, today’’s traditional-age college freshmen are "more materialistic and less altruistic (利他主义的)"than at any time in the 17 years of the poll.
Not surprising in these hard times, the student’’s major objective "is to be financially well off. Less important than ever is developing a meaningful philosophy of life." It follows then that today the most popular course is not literature or history but accounting.
Interest in teaching, social service and the "altruistic" fields is at a low. On the other hand, enrollment in business programs, engineering and computer science is way up.
That’’s no surprise either. A friend of mine (a sales representative for a chemical company) was making twice the salary of her college instructors her first year on the job—even before she completed her two-year associate degree.
