The blue, mystic Lake Ellsinore lies in
an inland California valley, which is teeming and steaming with hot springs.
Rimmed by shaggy mountains whose forested crests are reflected in its clear
waters, Lake Ellsinore is the very personification of peace--but on it rests the
curse of Tondo. The lake had a colorful history. Much of it lies buried in legend, and it is difficult to separate fact from fiction. There have been stories of underground volcanoes on the lake bottom, erupting, killing fish and discoloring the water. There have been stories of a playful sea serpent that lived in its depths. Long noted for its scenic beauty and health-giving waters, the lake was a famous resort in the Nineties. But long before the first white man had set foot along the shore of the lake, this part of California had been the home of the Sobo A. It is considered by legend to be rich in gold. B.

Professor Faulkner wanted to find out why healthy farmers in northern Japan appeared to be losing their ability to think and to reason at a relatively early age,and how the process of ageing could be slowed down.
He set about measuring brain volumes of a thousand people of different ages and occupations.
Computer technology enabled him to obtain precise measurements of the volume of the front and side sections of the brain,which relate to intelligence and emotion,and determine the human character.
Contraction of front and side parts--as cells die off--was observed in some subjects in their thirties,but it was still not evident in some sixty-and seventy-year-olds.
Faulkner concluded from his tests that there is a simple way to slow the contraction—using the head.
The findings show that contraction of the brain begins sooner in people in the country than in the towns.Those least at risk,says Faulkner,are lawyers,followed by university professors and doctors.White--collar workers doing routine work are,however,as likely to have shrinking brains as the farm worker,bus driver and shop assistant.
Faulkner's findings show that thinking can prevent the brain from shrinking.Blood must circulate properly in the head to supply the fresh oxygen the brain cells need."The best way to maintain good blood circulation is through using the brain,"he says."Think hard and engage in conversation.Don't rely on pocket calculators."
According to the passage,which group of people seem to age slower than the others?
A.Farmer B.Lawyer C.Clerk D.Shop assistant [单选题] 椭圆齿轮流量计转子每转动一周排出液体的体积是( )V0。
