10.Family structure is the core of any culture.A major function of the family is to socialize new members of a culture.As children are raised in a family setting,they learn to become members of the family as well as members of the larger culture.The family provides the model for all other relationships in society.Through the observations and modeling of the behavior of other family members,children learn about the family and society including the values of the culture.Family structure and their inherent relationships and obligations are a major source of cultural difference.
The family is the center of most traditional Asians'lives.Many people worry about their families'welfare,reputation,and honor.Asian families are often extended,including several generations related by blood or marriage living in the same home.An Asian person's misdeeds are not blamed just on the individual but also on the family-including the dead ancestors.
Traditional Chinese,among many other Asians,respect their elders and feel a deep sense of duty toward them.Children repay their parents'sacrifices by being successful and supporting them in old age.This is accepted as a natural part of life in China.In contrast,taking care of aged parents is often viewed as tremendous burden in the United States,where aging and family support are not honored highly.
The Vietnamese family consists of people currently alive as well as the spirits of the dead and of the as-yet unborn.Any decisions or actions are done from family considerations,not individual desires.People's behavior is judged on whether it brings shame or pride to the family.Vietnamese children are trained to rely on their families,to honor elderly people,and to fear foreigners.Many Vietnamese think that their actions in this life will influence their status in the next life.
Fathers in traditional Japanese families are typically strict and distant.Japanese college students in one study said they would tell their fathers just about as much as they would tell a total stranger.The emotional and communication barrier between children and fathers in Japan appears very strong after children have reached a certain age.
Although there has been much talk about"family values"in the United States,the family is not a usual frame of reference for decisions in U.S.mainstream culture.Family connections are not so important to most people.Dropping the names of wealthy or famous people the family knows is done in the United States,but it is not viewed positively.More important is a person's own individual"track record"of personal achievement.
Thus,many cultural differences exist in family structures and values.In some cultures,the family is the center of life and the main frame of reference for decisions.In other cultures,the individuals,not the family,is primary.In some cultures,the family's reputation and honor depend on each person's actions; in other cultures,individuals can act without permanently affecting the family life.Some cultures value old people,while other cultures look down on them.

7.Although millions of us love our fitness trackers,the popular devices may not help as much,with weight loss as we think.(61)Anarticle on the Mayo Clinic News Network says that one in five(62)Americans(American) wears a tracker,but most aren't seeing the hoped-for(期盼的)results.
"Having an activity tracker doesn't(63)necessarily(necessary) translate into'I'm a more fit person,'"says Kathleen Zeratsky,clinicial dietician(营养师)at Mayo,"or it's going to lead to automatic weight loss.An activity tracker is just a(64)helpful(help) tool."
In the report,Zeratsky says that the trackers do help(65)(to) keep(keep) people be more aware of the need to be active,but that isn't enough.You need to burn more calories than you're taking in,and for most of(66)us(we),that means a change in eating habits.
"If you're trying to lose weight,you want to have a calorie decrease from your activity,"she says."You don't want to destroy that by,say,(67)rewarding(reward) yourself with more calories with a rich meal."(68)Inother words,don't slow your progress by eating too much.
Zeratsky acknowledges that exercise can lead to hunger.But,she says,"if your body says'I'm hungry'while you(69)are having(have) more activity,well,then just choose to eat in a smart way(70)that/whichwon't damage your weight-loss efforts."

14.If you have a cat,you already know that a cat isn't a dog that doesn't have to be walked.If you're about to bring a cat into your family,you need to understand that basic fact.The common wisdom is that dogs are friendlier than casts.
In recent years,scientists who have done DNA studies have offered a better way to understand cats.Unlike other animals that people feed,cats domesticated themselves,and,in a way,trained humans.Cats decided to live close to humans because doing so benefited the casts themselves.
Studies show that cats have lived with humans for about 12,000 years,since people first settled down and started farming.When people started storing grain,mice arrived and started eating the grain.Clever cats figured out that mice settlements where people stored grain were easy for hunting,so they started hanging around.Cats did what they needed to do to get the people to let them stay,but they kept up their independence.Over time,cats allowed humans to get a bit closer to them.Later,the farmers did befriend the cats.Certainly,it didn't do them any harm because they could see the cats were really helping them out by eating mice.
Today,about a third of American families have cats.In most of those homes,the cats are still more interested in pleasing themselves than in pleasing their human families.A dog may do anything it can to make you happy,but kitty will teach you to make kitty happy.

33.Compared with dogs,cats areA.
A.colder
B.friendlier
C.more warm-hearted
D.more frightening
34.According to the text,why do cats decide to stay close to humans?A
A.To be useful to themselves
B.To protect grain from mice
C.To rely on humans for food
D.To keep up their independence
35.What may be the best title for the text?D
A.A common point between dogs and cats
B.The reasons why people like dogs
C.A disadvantage of raising cats
D.The basic fact about cats.
