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.

As awareness of the cenefits of humour increases, most of us want to get all the langhs we can. It seems that almost every day there is another new discovery about the power of humour to help us physically, mentally, cmotionally, and sp[iritually. Every system of the body responds to langhter in some important or positive way .
Many pcople 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.

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.

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.”

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.

Directions: Read the passage carefully. Then answer the questions or complete the statements in the fewest possible words.
Sociologists have long recognised that organisations of less than 200 individuals can operate through the free flow of information among the members. Once their size goes beyond this figure, the organizations are getting less flexible. So it seems necessary to prevent total disorder resulting from failures of communication.
One solution to this problem would, of course, be to structure large organisations into smaller units of a size that can act as a group. By allowing these groups to build reliance on each other, larger organizations can be built up. However, merely having groups of, say, 150 will never of itself be a complete solution to the problems of the organization. Something else is needed: the people involved must be able to build direct personal relationships. To allow free flow of information, they have to be able to communicate with each other in a casual way. Maintaining too formal a structure of relationships inevitably prevents the way a system works.
The importance of this was drawn to my attention two years ago by the case of a TV station. Whether by chance or by design, it so happened that there were almost exactly 150 people in the station. The whole process worked very smoothly as an organization for many years until they were moved into purpose-built accommodation. Then, for no apparent reason, the work seemed to be more difficult to do, not to say less satisfying.
It was some time before they work out what the problem was. It turn out that, when the architects were designing the new building, they decided that the coffee room where everyone ate their sandwiches at lunch times was an unnecessary luxury and so did away with it. And with that, they accidentally destroyed the close social networks that strengthened the whole organization. What had apparently been happening was that, as people gathered informally over their sandwiches in the coffee room, useful information was casually being exchanged.

How would you like to wear the same underwear (内衣裤) for weeks? Owing to the work that has gone into developing intelligent materials, this may not be as1as it sounds. Self-cleaning clothes have now been created, and these new materials provide2resistance to dirt as well as water. As a result, they require much less cleaning than traditional materials.

The creation of self-cleaning clothes provides an example of how nature helps scientists develop better products. This self-cleaning nature is known as the "lotus effect". The name comes, of course, from the lotus leaves, which are famous for growing in muddy lakes and rivers while remaining almost3clean. By observing nature, scientists are4the qualities of the lotus leaves to the materials they have engineered. Because of this, some remarkable new products have been5. Among them are special windows that are resistant to dirt and water. A special6on these windows not only prevents dirt from sticking to their surfaces, but also allows dust to be easily washed off by the rain. In fact, these new windows have already been7to some cars. Even when traveling at high speed through rain, these cars never have to use their windshield wipers (雨刮器).
Although we have already seen some practical applications, even more dramatic8will be made in the future, and they will, perhaps, change our world completely. Undoubtedly, technology is an important development, and it will have an even bigger9on our lives.
