Whenever we see a button, we are eager to press it because we know something will happen. This is true in most cases, for example on a doorbell and on the “on/off” button on the TV. But some buttons are actually fake, like the “close” button on a lift.

Many people are in the habit of pressing the “close” button because they don’t have the patience to wait for the lift doors to shut. But lifts’ “close” buttons are a complete scam, at least in the US—the doors will not close any faster no matter how hard you press.

It started in the 1990s when the Americans with Disabilities Act was passed in the US, making sure that all lifts stayed open long enough so that people with disabilities could enter. Only US firefighters and repairmen can use the buttons to speed up the door-closing process if they have a code or special keys.

But to normal lift riders, the buttons aren’t completely useless. According to psychologists, fake buttons can actually make you feel better by offering you a sense of control.

“Perceived (能够感知的) control is very important. It reduces stress and increases well-being,” Ellen J. Langer, a psychology professor, said, “Having a lack of control is associated with depression.”

Experts have revealed that a lot of buttons that don’t do anything exist in our lives for this same purpose. For example, many offices in the US have fake thermostats (温度调节器) because people tend to feel better when they think they can control the temperature in their workspace.

But psychologists found it interesting that even when people are aware of these little “white lies”, they still continue to push fake buttons because as long as the doors eventually close, it is considered to be worth the effort.

“That habit is here to stay,” John Kounios, a psychology professor, said, ‘‘Even though I have real doubts about the traffic light buttons, I always press them. After all, I’ve got nothing else to do while waiting. So why not press the button in the hope that this one will work?”

文章大意:这是一篇说明文。文章主要介绍了宇航员在国际空间站中的工作和生活情况。

【推荐1】Astronauts on shorter spaceship tasks often work very long days. Tasks are scheduled so tightly that break times are often used to finish the day’s work. This type of schedule is far too demanding for long missions on the International Space Station (ISS). ISS crewmembers usually live in space for at least a quarter of a year. They work five days on and two days off to mimic the normal way they do things on Earth as much as possible. Weekends give the crew valuable time to rest and do a few hours of housework. They can communicate with family and friends by email, Internet phone and through private video conferences.

While astronauts cannot go to a football game or a movie in space, there are many familiar activities that they can still enjoy. Before a mission, the family and friends of each ISS crewmember put together a collection of family photos, messages, videos and reading material for the astronauts to look at when they will be floating 370 kilometers above the Earth. During their mission, the crew also receives care packages with CDs, books, magazines, photos and letters. And as from early 2010, the Internet became available on the ISS, giving astronauts the chance to do some “Web surfing” in their personal time. Besides relaxing with these more common entertainments, astronauts can simply enjoy the experience of living in space.

Many astronauts say that one of the most relaxing things to do in space is look out of the window and stare at the universe and the Earth. Both the shuttle and the ISS circle the planet several times each day, and every moment offers a new view of the Earth’s vast land mass and oceans.

1. In Paragraph 1, what does the word “mimic” mean?
A.Admit.B.Cover.
C.Change.D.Copy.
2. According to the context, which of the following best describes the families of the astronauts on the ISS?
A.They are excited and fascinated.
B.They are worried and upset.
C.They are patient and annoyed.
D.They are caring and thoughtful.
3. In the last paragraph, the writer shows that astronauts         
A.get more pleasure in space than on the Earth
B.love to see the Earth from space
C.regard space life as common
D.find living in space a bit boring and tiring
4. The passage mainly discusses how astronauts        
A.work for shorter missions in space
B.spend their time in space
C.observe the Earth from space
D.connect with people on the Earth

【推荐2】Radar(雷达) is an electronic device that detects planes, ships, coastlines, landmarks, and even storm clouds. The name radar comes from the first letters of the words radio direction and ranging. As the human eye uses light waves to see, radar “sees” with radio waves. Without radar, planes could not land safely in bad weather and ships could not move safely in thick fog.    1    

In the 1800s it was discovered that radio waves could be reflected from objects. But scientists did not make great advances in radar research until the 1930s, when the world was threatened by war.    2     It has been used widely in almost every conflict since then.

Echoes make it possible for radar to work. When a beam of radio waves is sent out, it strikes on an object and returns an echo. This echo is picked up by radar and recorded on a screen similar to television screen. On the screen an observer sees a flash, or a blip, that shows the direction and distance of the object.    3    

Airport control towers use radar to guide planes in for safe landings. Almost all large ships depend on radar to prevent collisions with icebergs or other ships.     4    Weather forecasters “see” the size, direction, and speed of storms on radar screens. Astronomers can even use radar to measure accurately the distance to the moon. Thus, the device has generated major advancements.

    5     Huge radar antennas have been installed all over the United States. They guard us against possible enemy attacks. We have ballistic—missiles (战略导弹)warning systems that can alert us to attacks when missiles are more than 1,000 miles away. Other radar systems warn us against enemy aircraft and even spying space satellites.

A.Police track speeders in radar-equipped cars.
B.These measurements are now highly accurate.
C.The device can be used in a wide range of fields.
D.During World War II many countries used radar effectively.
E.It is therefore especially valuable to shippers and travelers.
F.Today radar is used by commercial airliners and weather forecasters.
G.Strengthening national defense is one of radar’s most important functions.

【推荐3】We’ve all had a guilty pleasure or two. Maybe it was an awkward TV show that we enjoyed a bit too much, maybe a song we listened to ironically until it became a bit too unironic. Perhaps a snack so disgusting it wound up coming back around to be delicious, or a movie so egregious that it ended up being a fantastic watch. Though we often wonder why we enjoy these things, we should really be asking ourselves why we feel guilty for enjoying them.

With the obvious exception of things that are harmful to people, our harsh judgment toward ourselves and others over what we enjoy does nothing but harm our individual expression and enjoyment.

It’s natural to want to appear “cool” to other people — whatever that may mean to you. With the cultural tendency and the means to share literally anything and everything you enjoy via social media, we perfectly curate (管理) the media we consume to match some sort of imagined ideal aesthetic (美学) — a trap that’s easy to fall into. Don’t fall into the trap!

My point is, the things that hold us back from openly enjoying our “guilty pleasures” often come from completely unfounded places. This is especially true that a teenage girl would rather be misunderstood than admit she likes pink. Frankly, what’s the point? Who are you proving yourself to, and why do you feel the need to? If you’re not harming anyone, and you are getting happiness from something, then why bother holding yourself back from it just to preserve some kind of curated image of who you’re supposed to be?

Life is hard enough. If you’ve found something that eases the stress of life even just a little bit, hold onto it for dear life. Marathon the Twilight movies. Read a super tacky (俗气的) romance novel. Throw that guilt right out of the window with absolutely no regrets, and do whatever it is that makes you happy.

1. What can we learn from paragraph 3?
A.Most people want to gain recognition from others.
B.Social media has a bad impact on self-recognition.
C.Cultural tendency sets a standard for ideal aesthetic.
D.People enjoy curating the media that they consume.
2. What would hold us back from enjoying “guilty pleasure”?
A.The desire to lead a simple life.B.The intention to show off ourselves.
C.The purpose to guard our ideal image.D.The need to admit that we like pink.
3. Which of the following may the author agree with?
A.Find ways to overcome hard life.
B.Set ourselves free from fixed opinions.
C.Have an in-depth self-talk to find our souls.
D.Talk with people and make our own decisions.
