Passage One
Many animals have an excellent sense of smell, which they use in hunting. On the other hand, their eyesight may be poor. Dogs, for example, have poor eyesight and no color vision. They see only shades of gray. But the dog’s sense of smell is extraordinary,
The kind of dog known as Alsatian has 220 million olfactory (嗅觉) cells. Man has five million. Scientists believe that the Alsatian is one million times better than man in finding out odors.
The human sense of smell, however, is really quite good. The average human being can distinguish more than 10 000 different odors.

The University of California at Davis has 3,800 rhesus macaque monkeys. It is one of the largest primate research labs. The activists sent letters to researchers at Davis and about eighty other researchers around the country, whose names were on the web pages. The warning letters had razor blades hidd

Many people think a telephone is essential. But I think it is a pest and a time waster.

If you have a telephone in your own house, you will admit that it tends to ring when you least want it to ring; when you are asleep, or in the middle of a meal or a conversation, or when you are just going out , or when you are in your bath. Are you strong-minded enough to ignore it, to say to yourself, "Ah, well it will all be the same in a hundred year’s time" You are not. You think there may be some important news or message for you. I can assure you that if a message is really important it will reach you sooner or later. Have you never rushed dripping from the bath, or chewing from the tab]e, or dazed from the bed, only to be told that you are a wrong number
