Question

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 as   41   as it sounds. Self-cleaning clothes have now been created and these new materials provide   42   resistance 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 almost   43 
clean. By observing nature scientists are   44   the qualities of the lotus leaves to the materials they have engineered. Because of this some remarkable new products have been   45  . Among them are special windows that are resistant to dirt and water. A special   46   on 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 been   47   to 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 dramatic   48   will 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 bigger   49   on our lives.
