16.Why College Is Not Home
The college years are supposed to be a time for important growth in autonomy(自主性) and the development of adult identity.However,now they are becoming an extended period of adolescence,during which many of today's students and are not shouldered with adult responsibilities.
For previous generations,college was decisive break from parental control; guidance and support needed help from people of the same age and from within.In the past two decades,however,continued connection with and dependence on family,thanks to cellphones,email and social media,have increased significantly.Some parents go so far as to help with coursework.Instead of promoting the idea of college as a passage from the shelter of the family to autonomy and adult responsibility,universities have given in to the idea that they should provide the same environment as that of the home.
To prepare for increased autonomy and responsibility,college needs to be a time of exploration and experimentation.This process involves"trying on"new ways of thinking about oneself bothe intellectually(在思維方面) and personally.While we should provide"safe spaces"within colleges,we must also make it safe to express opinions and challenge majority views.Intellectual growth and flexibility are fostered on debate and questioning.
Learning to deal with the social world is equally important.Because a college community(群體) differs from the family,many students will struggle to find a sense of belonging.If students rely on administrators to regulate their social behavior and thinking pattern,they are not facing the challenge of finding an identity within a larger and complex community.
Moreover,the tendency for universities to monitor and shape student behavior runs up against another characteristic of young adults:the response to being controlled by their elders.If acceptable social behavior is too strictly defined(規(guī)定) and controlled,the insensitive or aggressive behavior that administrators are seeking to minimize may actually be encouraged.
It is not surprising that young people are likely to burst out,particularly when there are reasons to do so.Our generation once joined hands and stood firm at times of national emergency.What is lacking today is the conflict between adolescent's desire for autonomy and their understanding of an unsafe world.Therefore,there is the desire for their dorms to be replacement homes and not places to experience intellectual growth.
Every college discussion about community values,social climate and behavior should include recognition of the developmental importance of student autonomy and self-regulation,of the necessary tension between safety and self-discovery.

67.What's the author's attitude toward continued parental guidance to college students?B
A.Sympathetic                          B.Disapproving
C.Supportive                           D.Neutral
68.The underlined word"passage"in Paraghaph 2meansA.
A.change                               B.choice
C.text                                 D.extension
69.According to the anthor,what role should college play?D
A.to develop a shared identity among students
B.to define and regulate students'social behavior
C.To provide a safe world without tension for students
D.To foster students'intellectual and personal development
70.Which of the following shows the development of ideas in the passage?C

13.On one of her trips to New York several years ago,Eudora Welty decided to take a couple of New York friends out to dinner.They settled in at a comfortable East Side cafe and within minutes,another customer was approaching their table.
"Hey,aren't you from Mississippi?"the elegant,white-haired writer remembered being asked by the stranger."I'm from Mississippi too."
 Without a second thought,the woman joined the Welty party.When her dinner partner showed up,she also pulled up a chair.
"They began telling me all the news of Mississippi,"Welty said."I didn't know what my New York friends were thinking."
    Taxis on a rainy New York night are rarer than sunshine.By the time the group got up to leave,it was pouring outside.Welty's new friends immediately sent a waiter to find a cab.Heading back downtown toward her hotel,her big-city friends were amazed at the turn of events that had changed their Big Apple dinner into a Mississippi
"My friend said:‘Now we believe your stories,'"Welty added.And I said:‘Now you know.These are the people that make me write them.'"
Sitting on a sofa in her room,Welty,a slim figure in a simple gray dress,looked pleased with this explanation.
"I don't make them up,"she said of the characters in her fiction these last 50 or so years."I don't have to."
    Beauticians,bartenders,piano players and people with purple hats,Welty's people come from afternoons spent visiting with old friends,from walks through the streets of her native Jackson,Miss,from conversations overheard on a bus.It annoys Welty that,at 78,her left ear has now given out.Sometimes,sitting on a bus or a train,she hears only a fragment(片段) of a particularly interesting story.

5.What happened when Welty was with her friends at the cafe?A
A.Two strangers joined her.
B.Her childhood friends came in
C.A heavy rain ruined the dinner.
D.Some  people held a party there.
6.The underlined word"them"in Paragraph 6 refers  to Welty'sD
A.readers    B.parties    C.friends    D.stories
7.What can we learn about the characters in Welty's fiction?C
A.They live in big cities
B.They are mostly women
C.They come from real life
D.They are pleasure seekers.
