填空题By this time next year my family (live) ____ in this small town for 20 years.

Some people do not like anything to be out of place;they are never late for work;they return their books on time to the library;they remember people's birthdays;and they pay their bills as soon as they arrive．Mr．Hill is such a man.
Mr．Hill works in a bank,and lives alone．The only family he has is in the next town:his sister lives there with her husband,and her son,Jack．Mr．Hill does not see his sister,or her family,from one year to the next,but he sends them Christmas cards,and he has not forgotten one of Jack's seventeen birthdays.
Last week Mr．Hill had quite a surprise．He drove home from the bank at the usual time,driving neither too slowly nor too fast;he parked his car where he always parked it,out of the way of other cars,and he went inside to make his evening meal．Just then,there was a knock at the door．He opened the door,to find a policeman standing on the door-step.
"What have I done wrong?"Mr．Hill asked himself．"Have I driven on the wrong side of the road?Has there been some trouble at the bank?Have I forgotten to pay an important bill?"
"Hello,Uncle,"said the policeman,"My name is Jack."

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.

The word“mobility” means
A:money
B:readiness to move
C:organization
D:skill
