Mother Nature knows best. But she's not always generous with her secrets. Sometimes she only tells them to the most careful observers.
George de Mestral was a Swiss engineer who enjoyed walking with his dog in the woods. One day,after a walk,he looked down and saw some seeds (種子) stuck to his trousers. He was a little -bit angry because the seeds were hard to remove. He pulled a few of the seeds off of his trousers and examined them under a microscope（顯微鏡） What he saw amazed him: tiny hooks (鉤子) on the ends of the seeds. De Mestral saw a new way to stick things together and keep them attached.
He was inspired to turn his accidental discovery into a useful product. He borrowed money from a bank,gave up his job,and gave all of his time and energy to the task. At first,people refused to take him,and the idea,seriously. He took his idea to a weaving center,where he did manage to get the help of one weaver,who made two products out of cotton that worked. However, the cotton wore out quickly. Finally,by using nylon instead of cotton,he made his invention work. It took ten years to develop it. He called it Velcro.
Today,Velcro is used everywhere: in shoes,purses,and children's toys. We can thank de Mestral for discovering and developing a wonderful way to attach things. But the real thanks should go to nature for making the secret known.

A. The thick woods. B. The sticky seeds.

B
For more than a century it was thought that a beautifol face was appealing because it was a co ection of average features. Using his computer system,Dr David Perrett of the University of St Andrews has challenged the theory. In a key experiment,photographs of women were ranked tor their attractiveness by a number of volunteers Two composite pictures were then created;
one,tile average of all the pictures,the other made lrom those rated most attractive. Although the faces looked very similar at first sight,most people said they preferred the composite of most attractive faces.
“The conclusion I reached," said Dr Perrett was that the most attractive face was not average. If you look at famous film stars and supermodels,most of them have Wefl/ (理想的) features 一 larger than normal eyes,higher arched eyebrows,slightly smaller noses,and higher cheekbones Even popular cartoon characters such as Betty Boop,Yasmin from Aladdin and Bambi have big eyes,small tumed-up noses,big mouths and small chins. And if these features are exaggerated,the attractiveness rating goes up even more. Julia Roberts is a good example of this."
But what do scientists make of men，s faces? Do men with large eyes,high cheekbones and a small chin have the same appeal? Researchers were a bit shocked at the top-ranking male face. They expected it to have the classic square jaw and strong cheekbones,but instead,women seem to prefer men with gentle faces.
Dr Perrett puts forward a reason to explain why so many women now go for baby-faced stars such as Leonardo DiCaprio and Jude Law. Women like a man with (女性化的) face because he is more likely to make a kinder and more trustworthy husband and father.
But do these ideals of beauty manage to cross cultural boundaries? Are the same features considered to be attractive all over the world? A worldwide study carried out by Professor Cunningham of the University of Louisville,Kentucky concluded that there were only very subtle differences between different cultures. In other words,although there might be a little truth in the old saying that beauty is in the eye of the beholder,by and large,we all seem to be attracted to the same things.
