Lesson 2-2 Spare that spider不要伤害蜘蛛
How many spiders are engaged in this work on our behalf? One authority on spiders made a census of the spiders in a grass field in the south of England, and he estimated that there were more than 2,250,000 in one acre; that is something like 6,000,000 spiders of different kinds on a football pitch．Spiders are busy for at least half the year in killing insects．It is impossible to make more than the wildest guess at how many they kill, but they are hungry creatures, not content with only three meals a day．It has been estimated that the weight of all the insects destroyed by spiders in Britain in one year would be greater than the total weight of all the human beings in the country.
