When you were young, ginger ale(姜味汽水)may have been a popular choice for reducing the unpleasant feelings caused by your upset stomach on the road to get to school. For years, ginger has been used to reduce the effects of nausea(作呕). But do you know it’s now also being looked at to fight cancer?

Scientists have discovered that ginger can kill cancerous cells in two different ways. On the one hand, ginger causes the cancer cells to “commit suicide” by destroying themselves while leaving the surrounding healthy cells untouched. Ginger can prevent the growth of diseased cells by destroying the environment they grow in. On the other hand, ginger tricks the diseased cells and causes them to fight among themselves. Researchers are now looking into one of the toughest cancers to fight. However, scientists find repeated treatment of disease by drugs can actually lose its effectiveness over time as the cancer builds up resistance(抵抗力)to the same treatment. This raises researchers’ confidence that ginger would help stop resistance from the cancer.

In a study, the cancer clearly stopped growing in the body of the mice that had been given ginger. The bad news is that such encouraging research has only been conducted on mice. The good news, however, is that it seems humans might be able to get the same benefit just by eating products with ginger and ginger root in them.

Cancer prevention and fighting abilities aren’t the only potential benefits you may get from adding a bit more ginger to your diet.

Drinking ginger ale when your stomach was upset as a child wasn’t just a placebo(安慰剂).Numerous studies and research, including the Mayo Clinic’s strict grading system, agree that ginger has some sort of anti-nausea characteristics.

Some believe that ginger works well against nausea after operations, while others use it to reduce motion sickness such as seasickness and car sickness. The Mayo Clinic, however, advises the use of ginger only to reduce nausea during pregnancy. While more research needs to be done, early studies are very promising, especially in that small amounts of ginger don’t seem to do any harm to the mother or baby.

Other health benefits from ginger exist as well. Since ginger is often considered to be useful in warming bodies, it can improve the condition of people’s joints including knees and ankle joints. Some suggest that ginger can help cure a cough associated with the common cold. Another benefit of ginger is that it seems to have no real side effects, which is one of the main reasons it appears to be safe during pregnancy.

But for safety, you should always consult a doctor for instructions on daily use before starting, even with something like ginger that seems to have little to no side effects.

After having more than a few acquaintances (熟人)online, _it might come a blow to keen social networkers like Barack Obama, or even Facebook founder Mark Zuckerberg himself.

According to a research, the average person has in fact twice as many online friends as physical ones. Users of social-networking sites have on average 121 online friends as compared with physical ones. The study also claims that people tend to be more open, confident and honest with their virtual friends than their “real” ones.

“For most people , the Internet is a way of keeping in touch with loved ones and friends, but for people who are isolated due to illness, it plays a more vital role, and can often act as a lifeline.” says Helen Oxley, a psychologist at Wythenshawe hospital.

“People with illnesses often rely on the Internet to facilitate(促进) friendships, since they blog and use networking sites as a way of dealing with their illness. It can foster a sense of social connection for those who frequently feel isolated, which is important to psychological well-being.”

In wider society, the ways in which friendships are formed are changing, with people recognizing that they can develop deep and meaningful connections with others that they’ve never met, and may never meet. About one in 10 people has either met their best friends online, or believes they can make lifelong friends on the Web.

The findings highlight how social introductions are also changing. Only five percent would ask for someone’s phone number, while 23 percent are now likely to ask for an email address or a full name with the intention of adding the person to their social network.

At the same time, however, a questionnaire completed by 4,427 suggests that 20 percent of parents believe their children’s education is affected by surfing the Net. They think their children are doing poorly at the school due to the amount of time they spend on non-educational websites.

1.The underlined word “it” in Para 1 most probably refers to ________.

A. people spending too much time surfing the Net

D. people tend to trust their virtual friends more than their real ones

3.What percentage of parents believe that the Internet has a bad effect on their children?

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.
