The Family
The structure of a family takes different forms around the world and even in the same society.The family's form changes as it adapts to changing social and economic influences.
Until recently,the most common form in North America was the nuclear family,consisting of a married couple with their minor children.The nuclear family is an independent unit,It must be prepared to fend for itself.Individual family members strongly depend on one another.There is little help from outside the family in emergencies.Elderly relatives of a nuclear family are cared for only if it is possible for the family to do so.In North America,the elderly often do not live with the family;they live in retirement communities and nursing homes.
There are many parallels between the nuclear family in industrial societies,such as
North America,and of families in societies such as that of the Inuits,who live in harsh environments.The nuclear family structure is well adapted to a life of mobility.In harsh conditions,mobility allows the family to hunt for food.For North Americans,the hunt for jobs and improved social status also requires mobility.
The nuclear family was not always the North American standard.In a more agrarian time,the small nuclear family was usually part of a larger extended family.This might have included grandparents,mother and father,brothers and sisters,uncles,aunts,and cousins.
In North America today,there is a dramatic rise in the number of single-parent households.
Twice as many households in the United States are headed by divorced,separated,or nevermarried individuals as are comprised of nuclear families.The structure of the family,not just in North America,but throughout the world,continues to change as it adapts to changing conditions.

Drying Ways for Food
1.Centuries ago,man discovered that removing moisture from food helps to preserve it,and that the easiest way to do this is to expose the food to sun and wind.In this way the North American Indians produce pemmican(dried meat ground into powder and made into cakes),the Scandinavians make stockfish and the Arabs dried dates and"apricot leather".
2.All foods including water,cabbage and other leaf vegetables contain as much as 93%water, potatoes and other root vegetables 80%,lean meat 75%and fish,anything from 20%to 60%,depending on how fatty it is.If this water is removed,the activity of the bacteria which causes food to go bad is checked.
3.Fruit is sun-dried in Asia Minor,Greece,Spain and other Mediterranean countries,and also in California,South Africa and Australia. The methods used vary, but in general,the fruit is spread out on trays in drying yards in the hot sun.In order to prevent darkening,pears,peaches and apricots are exposed to the fumes of burning sulfur before drying. Plums,for making prunes, and certain varieties of grapes for making raisins and currants,are dipped in an alkaline solution in order to crack the skins of the fruit slightly and remove their wax coating,so as to increase the rate of drying.
4.Nowadays most foods are dried mechanically.The conventional method of such dehydration is to put food in chambers through which hot air is blown at temperatures of about 110℃at entry and to about 43℃at exit. This is the usual method for drying such things as vegetables,minced meat, and fish.
5.Liquids such as milk,coffee,tea,soups and eggs may be dried by pouring them over a heated steel cylinder,by spraying them into a chamber through which a current of hot air passes.In the first case,the dried material is scraped off the roller as a thin film which is then broken up into small,though still relatively coarse flakes.In the second process,it falls to the bottom of the chamber as a fine powder. Where recognizable pieces of meat and vegetables are required,as in soup, the ingredients are dried separately and then mixed.
6.Dried foods take up less room and weigh less than the same food packed in cans or frozen, and they do not need to be stored in special conditions.For these reasons they are invaluable to the climbers,explorers and soldiers in battle,who have little storage space.They are also popular with housewives because it takes so little time to cook them.Usually it is just a case of replacing the dried-out moisture with boiling water.
Plums are dipped in an solution in order to______.
A.speed up dehydration
B.flakes
C.powder
D.controlled
E.increased
F.sun-dried
