For example, many wild primates use objects to threaten outsiders. Or【S1】________
there are many examples of tool use by the other mammals, as well as【S2】________
by birds and other types of animals.
Tools are used by many species in the capture or preparation of
food. Chimpanzees use sticks and poles to bring up ants and termites【S3】________
(白蚁)from their hiding places. Among the most complex tool use
observing in the wild is the use of stones by Ivory Coast chimpanzees to【S4】________
crack nuts open. They select a large flat stone as anvil(a heavy block【S5】________
on which to place the nuts)and a smaller stone as a hammer. Stones
suitable for use as anvils ale not easy to find, but often a chimpanzee【S6】________
may carry a haul of nuts more than 40 meters to find a suitable anvil.
The use of tools in chimpanzees is especially interesting while these【S7】________
animals sometimes modify tools t0 make them better suited theft intended【S8】________
purpose. To make a twig more effective for digging out termites, for
example, a chimp may first strip it of its leaves.
Surprisingly, there is also a species of bird that use sticks to probe【S9】________
holes in the search for insects. One of the species of Galapagos finch
(雀类), the woodpecker finch, picks up or breaks off a twig, cactus
spine, or leaf stem. This primitive tool is then held in their beak and【S10】________

directly with its beak. Birds have been seen to carry twigs from tree to
tree searching for prey. [br] 【S5】
