2.Americans are obsessed (着迷的) with telling their life stories.This phenomenon isn't simply the product of the technological world.(36)F.People are eager to tell stories and are fascinated by those of others.Even at preschool,"sharing time"is a common Monday-morning activity where the teenagers will sit in a circle and take turns telling a story about something they did over the weekend.
      (37)C.In many Asian countries,talking about and drawing attention to oneself can be seen as socially inappropriate.People are often unwilling to share their life stories and do not encourage others to do so.But there are also times when Asians do share their stories.(38)A.Asians believe that a person is largely decided by his or her social status and relationships,leaving little reason to broadcast detailed and revealing personal stories to establish a unique self.
    Ironically,the more unique Americans strive to be,the greater their need to feel connected with others.In their culture of individuality,relationships are highly mobile and can be easily formed or dissolved(破裂).
    Sharing personal stories brings them closer through the exchange of thoughts,feelings and desires.(39)E.But this motivation is not nearly as strong among Asians,for whom social relations are generally unconditional,obligatory(义不容辞的) and stable,and therefore require little maintenance(维护).
 (40)G.American parents encourage children to share their stories and create opportunities to re-experience the past with children.Asian parents,by contrast,engage their children in telling personal stories less frequently.When they do talk about a child's experiences,they are not particularly concerned with parent-child bonding but tend to focus on disciplining the child.

A.It helps them shape their"selves"and makes them who they are.
B.They tend to focus more on outer facts than personal details.
C.Talking about personal stories is to cheer people on with positive feelings.
D.It connects them like many different points,holding their society together.
E.Sharing personal stories is also an essential part in everyday conversations.
F.Parents in America and Asia differ in how they share memories with children.
G.Interestingly,this obsession is not necessarily shared in other cultures.

19.Advertising gives useful information about which products to buy.But modern advertising does more than gives news about products and services.Today's advertisements,or ads,try to get consumers to buy certain brands.Writers of advertising are so skillful that they can,sometimes persuade a consumer to wear a certain kind of clothing,eat a special kind of food,or see a movie.Consumers might never even want a product if they did not see or hear advertisements for it.
For example,you probab1y do not need the newest cereal in the supermarket.There are probably many cereal brands on your kitchen shelves.You may not have space on a shelf for another.But if you see ads about a new cereal that is your extra-tasty and has a free prize in the box,you may want it.
Advertising must get attention.To be effective,it must be exciting,entertaining,or provide some pleasure.The secret of writing good advertising copy is to offer a good idea as well as a product.The idea is what the ad is really selling.One example is an ad that says eating a certain cereal will make a person do well in sports.That cereal brand may sell better if consumers think it offers strength and energy.

C.cereal can make people strong
D.cereal is a kind of food which is popular among people
