Would you send a monkey to do your shopping
for you? Sounds very strange, doesn’t it ? But monkeys can be trained to do
some wonderful things. Most people know that monkeys are one of
36 cleverest beasts(兽). Scientists have been studying the connection（联系） __37__ monkeys and people
for a long time. They have done experiments that test __38__monkeys are able to
do simple things.
In one test, a scientist put two monkeys in
two cages beside each other. Each cage had a machine. One cage had a machine
which gave out water. __39__ had one which gave out food. Each monkey was given
_40__ black and white coins. The black coins worked _41_ in the food machine.
The white coins worked in the machine with the __42__. After some time, both
animals _43__ know which coin worked in which machine.
Then the test was made _44__. The coin s
were taken away. The monkey with the water machine was __45_ to have any water
for twenty-four hours. The food monkey was prevented from __46_ any food. The
next day, the coins were returned to the monkeys. This time, __47__, the monkey
with the food machine was given coins for water machine, and the monkey with
the water machine was given the coins that worked in the food machine. What did
the two __48__ monkeys do? The two clever monkeys __49__ through the bars (栅栏) of their cages and
__50_coins with each other.
