根据短文内容,从下框A~F选项中选出能概括每段主题的最佳选项。选项中有一项为多余项。
A. A sense of humour is not an inborn ability.
B. A sense of humour can be developed in our life.
C. A sense of humour helps us from several aspects.
D. A sense of humour means more than telling jokes.
E. A sense of humour can be expressed in many ways.
F. A sense of humour helps people to better enjoy life.
小题1:As awareness of the benefits of humour increases, most of us want to get all the laughs we can. It seems that almost every day there is another new discovery about the power of humour to help us physically, mentally, emotionally, and spiritually. Every system of the body responds to laughter in some important or positive way.
小题2:Many people mistakenly believe that we are born with a sense of humour. They think that when it comes to a sense of humour. “Either you have got it or you don’t.” This is
false! What is true, however, is that the ability to laugh and smile is actually something we are born with. For example, we laugh when we are tickled under the arm, even without thinking about how to react.
小题3:The parts of the brain and central nervous system that control laughing and smiling are mature at birth in human infants, but that is not the same thing as having a sense of humour. (After all, when a baby laughs in his small bed we don’t rush over and say, “That kid has a great sense of humour!”) Your sense of humour is something you can develop over a lifetime. Don’t be nervous before others and try to laugh at yourself-then you will make them laugh too.
小题4:Humour includes a lot more than laughing and joke telling. Many people worry needlessly that they do not have a good sense of humour because they are not good joke tellers. More than jokes, a sense of humour requires being willing and able to see the funny side of life’s situations as they happen. In fact, one of the best definitions(定义)of a sense of humour is “the ability to see the nonserious element in a situation.”
小题5:There may be a thousand different ways to express your sense of humour, but joke telling is only one of those ways. As more is discovered about how humour benefits our life, more people will be able to see and enjoy the humour when they are in a difficult situation. Life depends on air, food and water, but it is made easier to live with a good sense of humour.
