21.What makes us laugh? Why do we laugh?Well it's funny you should ask,but this question is a very interesting one to investigate.For what at first seems like a simple question turns out to require a surprisingly complex answer -- one that takes us on a journey into the very heart of trying to understand human nature. Most people would guess that we laugh because something is funny.But if you watch when people actually laugh,you'll find this isn't the case.Laughter expert Robert Provine spent hours recording real conversations at shopping malls,classrooms,offices and cocktail parties,and he found that most laughter did not follow what looked like jokes.People laughed at the end of normal sentences,in response to unfunny comments or questions such as "Look,it's Andre",or "Are you sure?".Even attempts at humor that provoked laughter didn't sound that funny. So if we want to understand laughter,perhaps we need to go deeper,and look at what is going on in the brain.The areas that control laughing lie deep in the sub cortex(下皮層),and in terms of evolutionary development these parts of the brain are ancient,responsible for primal(原始的) behaviors such as breathing and basic reflexes(反射).This means laughter control mechanisms are located a long way away from brain regions that developed later and control higher functions such as language or even memory. Perhaps this explains why it is so hard to control a laugh,even if we know it is inappropriate.Once a laugh is started deep within our brains these "higher function" brain regions have trouble interfering.And the opposite is true,of course.It is difficult to laugh on demand.If you consciously make yourself laugh it will not sound like the real thing - at least initially. But this does not fully answer the original question.To answer this,perhaps we need to look outwards,to look at the social factors at play when people laugh.Provine's study suggests that it isn't just some independent process that happens to us while we are talking to someone.He also found that laughter was most common in situations of emotional warmth and so-called "in-groupness". Perhaps "transmission" is another most important feature of laughter.Just listening to someone laugh is funny.You can even catch laughter from yourself.Start with a forced laugh and if you keep it up you will soon find yourself laughing for real. What these observations show is that laughter is both fundamentally social,and rooted deep within our brains,part and parcel of ancient brain structures.All these things are true.And biologists say each time we get closer to an answer for a fundamental question,it deepens our appreciation of the challenge remaining to answer the others.And there is a long way to go.

22.請閱讀下面文字,并按照要求用英語寫一篇 150 詞左右的文章. Dear Editor, I was shocked by the news that neighbors of a German university protested to the government that some students often gathered and shouted at night, disturbing local residents. They demanded if the students were not dismissed, they would move out of the area. I want to ask those young people: When you were letting off screams, were you aware that you were damaging other people's normal life? This doesn't happen by chance. I often witness similar things in our country, too. For example, throwing waste water onto the streets and spitting in public places can frequently be seen. Some tourists litter casually or even carve their names on ancient scenic spots! Many young people are fond of jumping queues and never offer their seats to the elderly. All over the world, people are beginning to worry that civilized behavior is a thing of the past. In fact, civilized behavior can help bring trust from others and success in the fierce world market competition. Therefore, increasing the quality of citizens is becoming urgent.
