Text 4Last summer, some twenty-eight thousand homeless people were afforded shelter by the city of New York. Of this number, twelve thou sand were children and six thousand were parents living together in families. The average child was six years old, the average parent twenty seven. A typical homeless family included a mother with two or three children, but in about one-fifth of these families two parents were present. Roughly ten thousand single persons, then, made up the remainder of the population of the city’ s shelter.These proportions vary somewhat from one area of the nation to another. In all areas, however, families are the fastest-growing sector of the homeless population, and in the Northeast they are by far the largest sector already. In Massachusetts, three-fourths of the homeless now are families with children; in certain parts of Massachusetts-Attleboro and Northampton, for example-the proportion reaches 90percent. Two thirds of the homeless children studied recently in Boston were less than five years old.Of the estimated two to three million homeless people nationwide, about 500,000 are dependent children, according to Robert Hayes, counsel to the National Coalition for the homeless. Including their parents, at least 750,000 homeless people in America are family members.What is to be made, then, of the supposition that the homeless are primarily the former residents of mental hospitals, persons who were carelessly released during the 1970s Many of them are, to be sure. Among the older men and women in the streets and shelters, as many as one-third ( some believe as many as one-half) may be chronically disturbed, and a number of these people left mental hospitals during the 1970s. But in a city like New York, where nearly half the homeless are small children with an average of six, to operate on the basis of such a supposition makes no sense. Their parents, with an average age of twenty-seven, are not likely to have been hospitalized in the 1970s, either. According to the passage, the author wants to tell us about()
A. one of the serious social problems
B. the present situation of the homeless
C. the make-up of the homeless
D. the life of the homeless
Text 3After watching my mother deal with our family of five, I can’ t understand why her answer to the question, "What do you do’ is al ways, "Oh, I’ m just a housewife. ’ JUST a housewife Anyone who spends most of her time in meal preparation and clean-up, washing and drying clothes, keeping the house clean, leading a scout troop, playing taxi driver to us kids when it’ s time for school, music lessons or the dentist, doing volunteer work for her favorite charity, and making sure that all our family needs are met is not JUST a housewife, She’s the real Wonder Woman.Why is it that so many mothers like mine think of themselves as second - class or something similar Where has this notion come from Have we males made them feel this way Has our society made "going to work" outside the home seem more important than what a house wife must face each dayI would be very curious to see what would happen if a housewife went on strike. Dishes would pile up. Food in the house would run out. No meals would appear on the table. There would be no clean clothes when needed. High boots would be required just to make it through the house scattered with garbage. Walking and bus riding would increase. Those scout troops would have to break up. Charities would suffer.I doubt if the man of the house would be able to take over. Oh, he might start out with the attitude that he can do just as good a job, but how long would that last Not long, once he had to come home each night after work to more household duties. There would be no more coming home to a prepared meal; he’ d have to fix it himself. The kids would all be screaming for something to eat, clean clothes and more bus fare money. Once he quieted the kids, he’d have to clean the house, go shopping, make sure that kids got a bath, and fix lunches for the next day. Once the kids were down for the night, he might’ be able to crawl into an unmade bed and ,try to read the morning newspaper.No, I don’ t think many males are going to volunteer for the job. I know I don’ t want it. So, thanks, mom ! I’ ll do what I can to create a national holiday for housewives. It could be appropriately called Wonder Woman Day. The main idea of the passage is about()
A. housewives, the wonder women
B. what would happen if housewives went on strike
C. the replacement of women by men as housewives
D. the setting up of a national holiday for housewives
