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 behavior? 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.

Chimpanzees, or chimps, can also be sneaky. After a fight, the losing chimp will give its hand to the other. When the winning chimp puts out its hand, too, the chimps are friendly again. But an animal expert once saw a losing chimp take the winner's hand and start fighting again.

Chimps are sneaky in other ways, too. When chimps find food that they love, such as bananas, it is natural for them to cry out. Then other chimps come running. But some clever chimps learn to cry very softly when they find food. That way, other chimps don't hear them, and they don't need to share their food.

As children, many of us learn the saying "You can't fool Mother Nature." But maybe you can't trust her, either.

Dogs already guide blind and disabled people and now they are to be trained to help people with dementia.The idea developed by some university students will now be put into practice by Scotland Medical Center.The research is meaningful, for there are 670, 000 people in Britain who have dementia and by 2021 this is expected to rise to one million.

Dementia can make people confuse night and day or forget basic things such as washing or drinking enough water.The dogs would be trained to help to guide them through the day.

Joyce Gray from Scotland Medical Center said, "People in the early stages of dementia are still able to live a relatively normal life, and dogs help them to maintain routine.M For example, people with memory loss will tend to forget to take medicine, "but if a dog presents them with a bag with pills in it, there's a greater chance of them taking it."

Ms.Gray also said dogs were perfectly suited to remind their owners to eat."Dogs have an ability to say 'it's my feeding time^, so there would be a note in the cupboard next to the dog's food reminding the dog's owner to eat too."

The dog would also encourage the owner to take them out for walks."It gives a reason for the owner to go out into the community," Ms.Gray said, "We did a test with an elderly person walking down the high street on his own.Then we gave him a dog on a lead and he did the exact same walk.That time people would come up to him, chatting or smiling and making eye contact.We hope we'd see this with people with dementia too."

There is one more advantage of using the pets as companions.Since conversation can be increasingly confusing for people with dementia, dogs can give them a sense of silent support and companionship.Ms.Gray said, "We have found that people may forget familiar faces but not pets.People light up when they see animals.There is a speechless bond between the dog and its owner.w

1.What's the common symptom of dementia?

A.Going hungry. B.Feeling lonely.

C.Forgetting things. D.Waking up at night.

2.According to Ms.Gray, after feeding the pet, the owner may ______.

A.do some washing B.take his medicine

C.have something to eat D.go out to walk the dog

3.For people with dementia, pets can ______.

A.give them wordless help

B.contribute to their recovery

C.help them to recognize people's faces

D.ensure them to gain support from other people

4.What's the best title for the passage?

A.Guide Dogs for the Mind

B.Pets, Faithful Companions

C.Mental Support for the Disabled

D.Dementia, a Curable Disease
