In every school there is a "top" crowd that sets the pace
(速度), while the others follow their example. Let’s say the top crowd decides
that it is smart to wear bright yellow sweaters. Pretty soon everybody is
wearing a bright yellow sweater. There is nothing wrong with that, except the
fact that for some people bright yellow is rather unsuitable. The situation can
even be- come dangerous, if the top crowd decides that it is smart to drink or
to drive cars at eighty miles an hour. Then the people who follow the
example are endangering their very lives. They are like sheep being led to the
butcher. Now, chances are that you have come across situations
like these more than once in your life. In fact, it is likely that at one time
or another you probably did something you knew to be wrong. You may have excused
yourself by saying, "Gee, the crowd does it." Well, let the crowd do it, but
don’t do it yourself. Learn to say "No!" Develop your own
standards and your own judgments. If you know the crowd is planning something of
which you disapprove (不赞同), have the courage to bow out politely. You’ll
have the satisfaction of standing on your own two feet. Remember this in your
heart, you are the unique (独一无二的) one in the world, just be yourself. The author disapproves of wearing yellow sweaters if ______.
A. the crowd is wearing them
B. you can’t afford them
