animal behavior托福阅读原文和答案
托福阅读真题练习：动物行为的文本
Some animal behaviorists argue that certain animals can remember past events,anticipate
future ones,make plans and choices,and coordinate activities within a group.These scientists,
however,are cautious about the extent to which animals can be credited with conscious
processing.
Explanations of animal behavior that leave out any sort of consciousness at all and ascribe
actions entirely to instinct leave many questions unanswered.One example of such unexplained
behavior:honeybees communicate the sources of nectar to one another by doing a dance in a
figure-eight pattern.The orientation of the dance conveys the position of the food relative to the
sun's position in the sky,and the speed of the dance tells how far the food source is from the hive.
Most researchers assume that the ability to perform and encode the dance is innate and shows no
special intelligence.But in one study,when experimenters kept changing the site of the food
source,each time moving the food 25 percent farther from the previous site,foraging honeybees
began to anticipate where the food source would appear next.When the researchers arrived at the
new location,they would find the bees circling the spot,waiting for their food.No one has yet
explained how bees,whose brains weigh four ten-thousandths of an ounce,could have inferred the
location of the new site.
Other behaviors that may indicate some cognition include tool use.Many animals,like the
otter who uses a stone to crack mussel shells,are capable of using objects in the natural
environment as rudimentary tools.One researcher has found that mother chimpanzees
occasionally show their young how to use tools to open hard nuts.In one study,chimpanzees
compared two pairs of food wells containing chocolate chips.One pair might contain,say,five
chips and three chips,the other four chips and three chips.Allowed to choose which pair they
wanted,the chimpanzees almost always chose the one with the higher total,showing some sort of
summing ability.Other chimpanzees have learned to use numerals to label quantities of items and
do simple sums.
