【正文】 ed 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。s story, gives us information byA．making us laughB．talking about whaling in general.

The third thing to bear in mind about failure is that it39。(5)Perhaps the most famous theory, the study of body movement, was suggested by Professor Ray Birdwhistell. He believes that physical appearance is often culturally（文化的）programmed. In other words, we learn our looks we are not born with them. A baby has generally unformed face features（特征）. A baby, according to Bird whistle, learns where to set the eyebrows（眉毛）by looking at those around family and friends. This helps explain why the people of some areas of the United States look so much alike, New Englanders or Southerners have certain mon face features that cannot be explained by genetics（遺傳學(xué)）. The exact shape of the mouth is not set at birth, it is learned after. In fact, the final mouth shape is not formed until well after new teeth are set. For many, this can be well into grownups. A husband and wife together for a long time often e to look somewhat alike. We learn our looks from those around us. This is perhaps why in a single country there are areas where people smile more than those in other areas. In the United States, for example, the South is the part of the country where the people smile most frequently. In New England they smile less, and in the western part of New York State still less. Many Southerners find cities such as New York cold and unfriendly, partly because people on Madison Avenue smile less than people on Peachtree Street in Atlanta, Georgi A．People in largely populated areas also smile and greet each other in public less than do people in small towns. 1．Ray Bird whistle believes physical appearanceA．has little to do with culture.

Once they knew the cause of the illness, the doctors were able to give the baby the correct treatment. She soon recovered and was sent back to Qatar. Later on it was proved that the poison might have e from an insecticide(殺蟲劑) used in Qatar. 1．Who first suggested the correct cause of the baby39。 s stomach becauseA．they could feel it moving about wildly.
