Looking back on my childhood, I am convinced that naturalists are born and not made. Although we were all brought up in the same way, my brothers and sisters soon left their pressed flowers and insects. Unlike them, I had no ear for music and languages. I was not an early reader and I could not do mental arithmetic.

Before World War I we spent our summer holidays in Hungary. I have only the dim(模糊的) memory of the house we lived in, of my room and my toys. Nor do I recall clearly the large family of grandparents, aunts, uncles and cousins who gathered next door. But I do have a clear memory of the dogs, the farm animals, the local birds, and above all, the insects.

I am a naturalist, not a scientist. I have a strong love of the natural world and my enthusiasm had led me into varied investigations（调查研究）. I love discussing my favorite topics and enjoy burning the midnight oil reading about other people’s observations and discoveries. Then something happens that brings these observations together in my conscious（清醒的） mind. Suddenly you fancy you see the answer to the riddle, because it all seems to fit together. This has resulted in my publishing 300 papers and books, which some might honor with the title of scientific research.

But curiosity, keen（敏锐的） eyes, a good memory and enjoyment of the animal and plant world do not make a scientist: one of the excellent and essential qualities required is self-discipline, a quality I lack. A scientist, up to a certain point, can be made. A naturalist is born. If you can combine the two, you get the best of both worlds.

A．has a great deal of trouble doing mental arithmetic

B．lacks some of the qualities required of a scientist

C．just reads about other people’s observations and discoveries

D．comes up with solutions in a most natural way

D

　　Beyond two or three days，the world’s best weather forecasts are doubtful, and beyond six or seven they are worthless.

　　The Butterfly Effect is the reason. For small pieces of weather—to a global forecaster，small can mean thunder—storms and blizzards（暴风雪）—any prediction becomes worse rapidly. Errors and uncertainties increase，from dust devils and storms up to continent-size eddies（旋涡）that only satellites can see.

　　The modern weather models work with net-like points sixty miles apart，and even so，some starting data have to be guessed，since ground stations and satellites cannot see everywhere. But suppose the earth could be covered with sensors placed one foot apart，rising at one-foot intervals all the way to the top of the atmosphere. Suppose every sensor gives perfectly accurate readings of temperature，pressure，humidity（温度）, and any other data a weatherman would want. Exactly at noon a powerful computer takes all the data and calculates what will happen at each point at 12.01, then 12.02，then 12.03…the computer will still be unable to predict whether Princeton will have sun or rain one month away. At noon the spaces between the sensors will hide fluctuations（波动）that the computer will not know about. By 12.01，those fluctuations will already have created small errors one foot away. Soon the errors will have added to the ten-foot scale，and so on up to the size of the globe.

63．A weather forecast ____________ in the world.

A．is reliable within one or two days

B．is doubtful beyond 24 hours

C．becomes useless beyond two or three days

D．is still worthwhile in seven days

64．Usually there is a weather sub-station____________.

A．in every city 　　　　　　　　　　B．every 60 miles

C．between two cities 　　　　　　　 D．every one foot

65．Which of the following statements is true？

A．People have not placed sensors one foot apart in the atmosphere.

B．Scientists have already put sensors one foot apart in the world.

C．Every sensor gives perfectly accurate data a weatherman wants.

D．Ground weather stations and satellites can see every place on earth.

66．Our computer will not be able to know about fluctuations because ____________.

A．the sensors are not good enough

B．they are hidden by the spaces between the sensors

C．they are too far away

D．they move very fast
