人类的老师

       科学家研究了蝙蝠飞行的秘密     从中得到启示     发明了雷达    可以说    蝙蝠是人类的老师 
       其实,自然界充当人类老师的生物何止蝙蝠一种?从前,在大海中航行的轮船,虽然头是尖尖的,但总是开不快,而那些有圆圆的大头的鲸,却常常轻而易举地超过海轮,什么原因呢?科学家们仔细研究了鲸,发现它的外形是一种极为理想的“流线体”,而“流线体”在水中受到的阻力是最小的。后来,工程师很快就模仿了鲸的形体,改进了船体的设计,大大提高了轮船航行的速度。
       一个人握住一个鸡蛋使劲地捏,可是(       )怎样用力,(       )不能把鸡蛋捏碎,薄薄的蛋壳怎么这样牢固呢?科学家们怀着极大的兴趣研究这个问题,终于发现薄薄的蛋壳(       )能承受这么大的压力是
(       )它能够把受到的压力均匀地分散到各个地方,建筑师们根据这种“薄壳结构”的特点,设计出许多(       )轻便(       )省料的建筑物。人民大会堂和北京火车站,以及其他很多著名的建筑物,都是这样“薄壳结构”的屋顶。
       此外,人们还模仿大袋鼠造出了会跳跃的汽车,模仿某些贝壳制成了外壳坚固的坦克,模仿一些大树的性能建造了高耸入云的塔。  
       自然界的生物真是人类的好老师啊!

     The summer I was ten, my mother decided to bring us to the world of art. My brother and I were not

very excited when we realized what my mother meant. What she meant was not that we could take

drawing classes or painting classes but that we would have to spend one afternoon a week with her at

the Fine Arts Museum. Before each visit to the museum, she made us read about artists and painting

styles(风格). It was almost as bad as being in school. Who wants to spend the summer thinking about

artists when you could be with your friends at the swimming pool?

     First we had to read about ancient Egyptians(古埃及人) and their strange way of painting faces and

then go to look at them at the museum. My 12-year-old brother thought this was so funny, but I was not

interested. Later we had to learn about artists in the Middle Ages who painted people wearing strange

long clothing. We had to look at pictures of fat babies with wings and curly (鬈曲的) hair and with no

clothes on flying around the edges of paintings. I certainly couldn't see what was so great about art.

     On our last visit to the museum, something happened when I saw a painting by a woman called Mary.

In it, a woman was reading to a child. The colors were soft and gentle, and you could tell by the mother' s expression how happy she was just to be with the child. I couldn't stop looking at this painting ! I wanted

to see every painting Mary had ever made! It was really worth looking at so many paintings to find a

painter who could interest me so much.
