【正文】 Washingtom,April4The United States has more than 90millon families for the first time ,but each contains fewer people on average than ever ,the Census Bureau(統(tǒng)計局) reported today.The 90,031,000 families in the United States averaged members each as of last July 1.“The reason is, in effect, changes in the age structure,” explained Campbell Gibson, a population researcher for the bureau. Most Americans born in the great explosion of births after World War II are mow in their 20’s and 20’s when they are most likely to set up families, he said.The fact that many are doing so increased the number of families from in 1980 to million in 1986 and past the 90 million mark last summer . At the same time, the average number of people per family dropped from in 1935 to in 1986 and then to ,Mr Gibson said.By parison, the 1970 Census found the average family contained people Families averaged more than four people in 1939 and more than five in 1880. The growing number of ever smaller families is still going on, but Mr Gibson pointed out that family growth was mot the same as population increase in the 1970’s. The same age factors (因素) that are increasing the number of families also happened then, but in the 1970’s the proportion(比例) of families in each age group was also growing .That has not continued in the 1980’s for a number of possible reasons, Mr Gibson said.For example, in the 1880’s more young people have chosen to remain home with their parents instead of setting up housekeeping on their own ,as many did in the 1970’s. This could be caused by the increasing cost of housing, he said. Delays in marriage while was not the only factor for the family changes. smaller figure of families reported here is ______.A．1980 B． 80,400,0。答案：DABDC(12) s stomach.C．dead body of the whale.D．whale39。s story, gives us information byA．making us laughB．talking about whaling in general.

Worms and insects had eaten the bag and everything in it. And of course, these are stories about people who bury things and either forget where they have buried them or lose the map.
