On Friendship

Few Americans stay put (固定不动的)for a lifetime. We move from town to city to suburb, from high school to college in different states, from a job in one region to a better job elsewhere, from the home where we raise our children to the home where we plan to live in retirement. With each move we are forever making new friends, who become part of our new life at that time.
For many of us the summer is a special time for forming new friendships. Today millions of Americans vacation abroad and they go not only to see new sights but also--in those places where they do not feel too strange--with the hope of meeting new people.

Yes, that college tuition bill was bigger this year. States are passing along their budget woes to public university students and their families. Tuitions are rising by double digits in some states, while the amount of state-funded student aid is dropping.

[单项选择]

Why do so many Americans distrust what they read in their newspapers The American Society of Newspaper Editors is trying to answer this painful question. The organization is deep into a long self-analysis known as the journalism credibility project.
Sad to say, this project has turned out to be mostly low-level findings about factual errors and spelling and grammar mistakes, combined with lots of head-scratching puzzlement about what in the world those readers really want.
But the sources of distrust go way deeper. Most journalists learn to see the world through a set of standard templates (patterns) into which they plug each day’s events. In other words, there is a conventional story line in the newsroom culture that provides a backbone and already-made narrative structure for otherwise confusing news.
There exists a social and cultural disconnect between journalists and their readers, which helps explain why the "standard templates" of th
