单选题 阅读下列短文，从每题所给的四个选项(A、B、C和D)中选出最佳选项。{{B}}A{{/B}} Christmas Eve arrives at my house each year. The center of the celebration is dinner. My mother spends days preparing a rich variety of seafood. The guest list seldom changes. It is made up of my aunt, Marcy and her husband, my oldest brother, Sal, his wife, and their four children, my sister, Joann, her husband, and their two children, and my second brother, Richard, his wife, and their two children. My aunt and uncle always come heavily loaded with enough food and wine for a whole army. My brother Sal and the {{U}}gang{{/U}} usually show up an hour early and empty-handed. Joann's family is usually late while Richard's group generally arrives on time, bearing gifts for everyone. I am in charge of getting the Christmas tree. Plenty of food is served at the dinner table, and all the hours of preparation are wolfed down in a matter of minutes. Along with the yearly repeated menu comes the yearly repeated conversation. Everyone talks about how good the food tastes. My mother then talks about all the supermarkets from which the fish was bought. This begins our period of comparison shopping. For at least 30 minutes, we show how better we are than each other at mentioning the bargains we have found. Personally, I do not feel the need to be with a crowd on Christmas Eve. Christmas Eve, to me, is a quiet time, a time to think deeply. The over-crowdedness and noise ruin my feelings about Christmas.

单选题Parents have to do much less for their children today than they used to do, and home has become much less of a workshop. Clothes can be bought ready made, washing can go to the laundry, food can be bought cooked, canned, bread is baked and delivered by the baker, milk arrives on the doorstep, meals can be had at the restaurant, the workers" canteen, and the school dining-room. It is unusual now for father to pursue (追求) his trade of other employment at home, and his children rarely, if ever, see him at his place of work. Boys are therefore seldom trained to follow their father"s occupation (职业), and in many towns they have a fairly wide choice of employment and so do girls. The young wage-earner often earns good money, and soon acquires a feeling of economic independence. In textile (纺织品的) areas it has long been a custom for mothers to go out to work, but this practice has become so widespread that the working mother is now not an unusual factor in a child"s home life, the number of married women in employment having more than doubled in the last 25 years. With mother earning and older children drawing much salaries father is seldom the controlling figure that he still was at the beginning of the century. When mother works, economic advantages increase, but children lose something of great value if mother"s employment prevents her from being home to greet them when they return from school.
