请认真阅读下列短文,并根据所读内容在文章后表格中的空格里填入最恰当的单词.
注意:每个空格只填1 个单词.
     If we agree that the function of education is to prepare us for life, then there is very little time to waste. So, while we can, we ought to concentrate on teaching children something really useful. Here is what our
schools should teach.
     Politeness is a mark of civilization. The sooner children learn this, the better. In any case, a lot can be
accomplished by a smile and good manners.
     Like it or not, our adult lives will be consumed by the struggle for money, but we don't make an effort
to teach children how to manage it. So our schools have a duty to teach them this ability from the
beginning.
     We're likely to accept something we are told, but that's not what educated people do. Educated
people are reasonable and they look at facts. If our schools teach nothing else, they should at least teach
critical ( 批判性的) thinking.
     Children should learn to take care of their health. They should know that if they eat junk food ( 垃圾
食品) ,they will become fat and unhealthy. They should be very clear about what happens to their bodies when they drink or smoke.
    All of us are part of society. We have rights and responsibilities. We ought to understand what they
are.   We have to know a little bit of our history and geography, because we need to have an environment
in which to relate to the people around us.
     How will we test students on these? We can't. But that's not a reason to avoid teaching what is
important. Our schools should spend every moment they have telling this to our children :"This is life, this
is what you are going to face, and this is how you deal with it."
