Unit 2 Robots (60分钟81分) Part A 一、阅读理解(共8小题;每小题2分,满分16分) A Most people agree that honesty is a good thing.But does Mother Nature agree?Animals can’t talk,but can they lie in other ways?Can they lie with their bodies and behaviors?Animal experts may not call it lying,but they do agree that many animals,from birds to chimpanzees,behave dishonestly to fool other animals.Why?Dishonesty often helps them survive. Many kinds of birds are very successful at fooling other animals.For example,a bird called the plover sometimes pretends to be hurt in order to protect its young.When a predator(猎食动物)gets close to its nest,the plover leads the predator away from the nest.How?It pretends to have a broken wing.The predator follows the “hurt” adult,leaving the baby birds safe in the nest. Another kind of bird,the scrub jay,buries its food so it always has something to eat.Scrub jays are also thieves.They watch where others bury their food and steal it.But clever scrub jays seem to know when a thief is watching them.So they go back later,unbury the food,and bury it again somewhere else. Birds called cuckoos have found a way to have babies without doing much work.How?They don’t make nests.Instead,they get into other birds’ nests secretly.Then they lay their eggs and fly away.When the baby birds come out,their adoptive parents feed them. |
