【題目】

When taking an elevator，do you often push the"Close"button？You hope by pushing it，the elevator door will close faster．But what if the button is actually fake（假的）？

Karen Penafiel is the executive director（執(zhí)行董事）of the US'NationalElevator Industry．She said that elevators'"close"buttons are a complete trick，at least in the US，and that doors will not close any faster despite how hard you push．

In the 1990s the Americans with Disabilities Act （《美國(guó)殘疾人法案》）

was passed in the US．It means all elevators have to stay open long enough to allow disabled people to enter．Only US firefighters and elevator workers can really use the buttons with special keys．

But the buttons aren't completely useless．According to psychologists（心、理學(xué)家），fake buttons can make you feel better．They give you a sense of control that can help reduce stress．That's why some other buttons in our lives are fake，too， For example，many offices in the US have fake thermostats（溫控器）．People may feel better when they think they can control the temperature in their workspace．

You were told that traffic light buttons could help make the traffic signals change faster．But they may not really work either．

However，even when people know these little"white lies"，they still push fake buttons．As long as the doors finally close，it seems worthy， John Kounios is a psychology professor at Drexel University in the US．He told The New York Times that he always pushes the traffic light buttons．"After all，I've got nothing else to do while waiting．So why not push the button on the off chance that this one will work？"

【1】The"close"buttons of the elevators in the US don't really work，do they？_____

【2】What do people hope when they push the"close"button in an elevator？_____

【3】Who can really use the"close"buttons of elevators in the US according to the passage？_____

【4】Why do the fake buttons make people feel better？_____

【5】What other examples does the passage show that fake buttons aren't completely useless？_____

【6】Will you push the fake buttons next time when you take the elevator or wait at the traffic lights？Why or why not？_____．

Facts you don’t know about animals

People have already known a lot about animals. However, there are still some things about animals that may surprise you. Here are some facts about animals you probably didn’t know.

Cows

Cows do have best friends and feel stressed (焦慮的) when they are separated (分開). Sometimes they even a【1】 humans when they are too nervous and angry. However, scientists also found that cows are very social animals and a cow always makes friends with other cows in the herd (獸群). When a cow is with its friend, its heart rate is reduced compared with when it is a【2】 or with a cow from another herd.

Penguins

During breeding (繁殖) season, a male penguin will offer a pebble (卵石) to a female penguin as a g【3】. If she takes it, they will become partners. When the female penguin lays an egg, she and her husband may c【4】 it on their feet, because some penguins don’t build nests.

Crocodiles

When crocodiles eat something, they always swallow (吞) their prey. They don’t chew it like other animals. To help with digestion (消化), they swallow stones which grind up the food in their stomachs. But these stones can h【5】 be defecated (排泄掉), so they may stay in their stomachs all their lives.

Elephants

Elephants use plants to get rid of p【6】 or other illness. Scientists once found a pregnant (懷孕的) elephant in Kenya who kept eating a kind of plant for a few days, while this kind of plant was not part of her regular d【7】. Four days later, she could give birth to a baby elephant quietly. The same plant was used by the local women to help with labor (分娩).

Do you find these facts amazing? Maybe you can introduce some of them to your friends and see how surprised they are when they know the facts!
