what they think and feel.
College students today have strong opinions about right and wrong. They are deeply interested in making a
better life for all people, especially for those who have not been given a fair chance before now. They see much
that is wrong in the lives of their parents. It is hard for them to see what is right and good in the older ways. As
a result, there is often trouble in American families. Your country may be meeting such problems, too.

Food banks are the organizations to help these poor people. Food banks receive the food from companies or supermarkets, and also from donations from the public. In this way, they collect extra food and give out the food to people who are hungry.
The first food bank was St. Mary"s Food Bank. It started in 1967 in Arizona. In 1979, it became a larger organization named America"s Second Harvest Network-made up of over 200 food banks across the USA. Each year, the Network provides food for more than 25 million hungry people in the United States, including more than 9 million children and nearly 3 million old people.
Volunteers are important to food banks. There are many different ways for you to volunteer. You can help out through activities such as:

A new study from the University of Essex in Britain has shown that the more friends you have in school,
the more money you"ll earn later.
The idea that popularity could have a serious impact on one"s earning potential shouldn"t come as too much
of a surprise. The researchers noted that if you want to get ahead in life, social skills and networking are easily
as powerful as talent and hard work.
"If a person has lots of friends, it means that he or she has the ability to get along with others in all kinds
of different situations," said Xu Yanchun, 17, from Nantou High School in Shenzhen, who totally agreed with
the recent finding. "Also, friends always help each other. They not only create wider social circles for you but
lift your mood when you occasionally feel depressed," said Xu.She believed that all this helps you "earn a
higher salary".
Maybe that"s why some people think the younger generations are in the age of Friendalholism (交友狂症).
A woman even complained that the networking website Facebook"s 5,000-friend limit was too low for her
large reserve of social contacts.
But what does a friend mean? Should friends be regarded as a form of currency?
"Call me uncool, but I think of a friend as an actual person with whom I have an actual history and whom
I enjoy actually seeing.It seems, however, that this is no longer the definition (定义) of "friend"," said Meghan
Daum, who works with The Los Angeles Times in the US.
B. the more friends you have in school, the more money you"ll earn in your late life.
C. the less friends you have, the poor lives you will live.
D. friends can make more money for you.
B. You will not feel lonely.
C. You are quite content with your life.
D. You have the ability to get along with others in various situations.
B. Friends play a more important part in our daily life than anything else.
C. Friends are currency.
D. Friends give you success.
B. Graduating from college means that you can make a fortune in the future.
C. Friends mean a form of currency.
D. Friends can make you wider social circle and make you feel better when you feel depressed.
seriously. Beijing University will enroll (招收) students recommended by high school principals this year.
If the students recommended pass a round of interviews by Peking University, they will have an extra 30
extra points added to their national college entrance exam scores if they apply to the university.
Beijing University said the reason behind the move was a desire to give students with comprehensive
(综合的) or special abilities a chance to stand out.
However, a survey, showed 10,046 out of 14,227 people are against the measure. Some experts agree
with the criticism. Liu Daoyu, former president of Wuhan University is one strong opponent(反对者)."There
are so many high schools across the country. But only 39 schools are qualified to recommend students. Is
it fair to the rest of the schools? Besides, most of the 39 schools are located in big cities, which is unfair to
other regions,"
The reform is also unfair to other students, some say. According to Liu, in the competitive exam, one
extra point can put a student ahead of a large numbers of other-never mind 30.
"Principals do not know students well. How can they guarantee the recommendation will be fair?" asked
Wang Xuming, former spokesman of the Ministry of Education.
The Ministry of Education said the move is a good experiment in college admission reforms and the public
should support it even if it is not yet mature (成熟的). It said Beijing University promised a series of
supervision (监督) measures to avoid cheating. For example, the information of schools and principals that
recommend students, and the recommended students will be put online for a week for public supervision.

C. all the recommended students will be accepted
D. no more than 70% of the people are against the reform
B. will be admitted into Beijing University
