Have you ever pressed the pedestrian button at a crosswalk and wondered if it really worked?　 They’re called “placebo(安慰剂）buttons”一buttons that mechanically sound and can be pushed，but provide no functionality.

In New York City, only about 100 of the 1, 000 crosswalk buttons actually function. Crosswalk signals were generally installed before traffic jam had reached today’s levels.

But while their function was taken over by more advanced systems—such as automated lights or traffic sensors — the physical buttons were often kept, rather than being replaced at further expense. Other cities，such as Boston，Dallas and Seattle，have gone through a similar process, leaving them with their own placebo pedestrian buttons. In London, which has 6, 000 traffic signals, pressing the pedestrian button results in a reliable “Wait” light. But that doesn’t necessarily mean that the “green man”— or “pedestrian stage” in traffic signal design profession — will appear any sooner.

“We do have some crossings where the green light comes on automatically, but we still ask people to press the button because that enables accessible features,’’ said Glynn Barton, director of network management at Transport for London.

These features, such as blind tracks and hearable traffic signals, help people with visual disorder cross the road and only function when the button is pressed. As for the lights, a growing number of them are now combined and become a part of an electronic system that detects traffic and adjusts time frequency accordingly (giving priority to buses if they’re running late, for example), which means that pressing the button has no effect.

According to Langer, a Harvard psychologist, placebo buttons give us the illusion (错觉)of control — and something to do in situations where the alternative would be doing nothing. In the case of pedestrian crossings, they may even make us safer by forcing us to pay attention to our surroundings. “They serve a psychological purpose at the very least,” she added.

1.Why are the physical buttons still kept in some cities?

A. Because it may cost money to replace them.

B. Because they remain as memories of a city.

C. Because do have real functions in traffic.

D. Because they can result in reliable lights.

2.Which of the following word can replace the underline word “features” in Paragraph 4?

A. Functions. B. Uses.

C. Equipment. D. Facilities.

3.If you pressed a “placebo button” in London, what would happen?

A. All traffic would be affected. B. Some kind of sound might appear.

C. Pedestrians came first to cross the road. D. “Green man” were bound to show up earlier.

4.What can we know about “placebo buttons” from Langer’s words?

A. They can really control traffic. B. They serve little functions.

C. They may work mentally. D. They can help the blind.

Have you ever wondered why birds sing? Maybe you thought that they were just happy. After all, you probably sing or whistle when you are happy.

Some scientists believe that birds do sing some of the time just because they are happy. However they sing most of the time for a very different reason. Their singing is actually a warning to other birds to stay out of their territory.

Do you know what a “territory” is? A territory is an area that an animal, usually the male, claims as its own. Only he and his family are welcome there. No other families of the same species are welcome. Your yard and house are your territory where only your family and friends are welcome. If a stranger should enter your territory and threaten you, you might shout. Probably this would be enough to frighten him away.

If so, you have actually scared the stranger away without having to fight him. A bird does the same thing. But he expects an outsider almost any time, especially at nesting（筑巢）season. So he is screaming all the time, whether he can see an outsider or not. This screaming is what we call a bird’s song, and it is usually enough to keep an outsider away.

Birds sing loudest in the spring when they are trying to attract a mate and warn others not to enter the territory of theirs.

You can see that birds have a language of their own. Most of it has to do with attracting mates and setting up territories.

1.Some scientists believe that most of the time bird’s singing is actually________.

A. an expression of happiness　 　　 B. a way of warning

C. an expression of anger　 　　　　 D. a way of greeting

2.What does the underlined word “territory”　 mean?

A. A place where families of other species are not accepted

B. A place where a bird may shout at the top of its voice

C. An area for which birds fight against each other

D. An area which a bird considers to be its own

3.Why do birds keep on singing at nesting season?

A. Because they want to invite more friends

B. Because their singing helps frighten outsiders away

C. Because they want to find outsiders around

D. Because their singing helps get rid of their fears

4.How does the writer explain bird’s singing?

A. By comparing birds with human beings

B. By reporting experiment results

C. By describing birds’ daily life

D. By telling a bird’s story
