1 . You may not pay much attention to your daily elevator (电梯) ride. Many of us use a lift several times during the day without really thinking about it. But Lee Gray, PhD of the University of North Carolina, US, has made it his business to examine this overlooked form of public transport. He is known as the “Elevator Guy”.

“The lift becomes this interesting social space where etiquette (礼仪) is sort of strange,” Gray told the BBC. “Elevators are socially very interesting but often very awkward places.”

We walk in and usually turn around to face the door. If someone else comes in, we may have to move. And here, according to Gray, lift users unthinkingly go through a set pattern of movements. He told the BBC what he had observed.

He explained that when you are the only one inside a lift, you can do whatever you want — it’s your own little box.

If there are two of you, you go into different corners, standing diagonally (对角线地) across from each other to create distance.

When a third person enters, you will unconsciously form a triangle. And when there is a fourth person it becomes a square, with someone in every corner. A fifth person is probably going to have to stand in the middle.

Newcomers to the lift will need to size up the situation when the doors slide open and then act decisively. Once in, for most people the rule is simple-look down, or look at your phone.

Why are we so awkward in lifts?

“You don’t have enough space.” Professor Babette Renneberg, a clinical psychologist at the Free University of Berlin, told the BBC. “Usually when we meet other people we have about an arm’s length of distance between us. And that’s not possible in most elevators.”

In such a small, enclosed space it becomes very important to act in a way that cannot be construed (理解) as threatening or odd. “The easiest way to do this is to avoid eye contact,” she said.

6 . With the development of our society, cellphones have become a common part in our lives. Have you ever run into a careless cellphone user in the street? Maybe they were busy talking, texting or checking updates on WeChat without looking at what was going on around them. As the number of this new "species" of human has kept rising, they have been given a new name—phubbers (低头族).

Recently a cartoon created by students from China Central Academy of Fine Arts put this group of people under the spotlight. In the short film, phubbers with various social identities bury themselves in their phones. A doctor plays with his cellphone while letting his patient die. A pretty woman takes a selfie (自拍) in front of a car accident site. And a father loses his child without knowing about it while using his mobile phone. A chain of similar events will finally lead to the destruction(毁灭) of the world.

Although the ending of the film sounds unrealistic, the damage phubbing can bring is real. Your health is the first to bear the effect and the result of it. "Always bending your head to check your cellphone could damage your neck," Guangming Daily quoted doctors' words. "The neck is like a rope that breaks after long-term stretching." Also, staring at cellphones for a long time will damage your eyesight gradually, according to the report.

But that's not all. Being a phubber could also damage your social skills and drive you away from your friends and family. When getting together with family or friends, many people prefer to play their cellphones while others are chatting happily with each other and this creates a strange atmosphere, Qilu Evening News reported.

It can also cost your life. There have been lots of reports on phubbers who fell to their death, suffered accidents, and were robbed of their cellphones in broad daylight.

7 . A simple piece of clothesline hangs between some environmentally friendly Americans and their neighbors.

On one side stand those who see clothes dryers as a waste of energy and a major polluter of the environment. As a result, they are turning to clotheslines as part of the " what-I-can-do-environmentally".

On the other side are people who are against drying clothes outside, arguing that clotheslines are unpleasant to look at. They have persuaded Homeowners Associations (HOAs) to ban（禁止） outdoor clotheslines, because clothesline drying also tends to lower home value in the neighborhood. This had led to a Right-to-Dry Movement that is calling for laws to be passed to protect people's right to use clotheslines.

So far, only three states have laws to protect clotheslines. Right-to-Dry supporters argue that they should be removed.

Matt Reck, 37, is the kind of eco-conscious person who feeds his trees with bathwater and reuses water drops from his air conditioners to water plants. His family also uses a clothesline. But on July 9, 2007, the HOA in Wake Forest, North Carolina told him that a dissatisfied neighbor had telephoned them about his clothesline. The Recks paid no attention to the warning and still dried their clothes on a line in the yard. " Many people say they are environmentally friendly but they don't take matters in their own hands," says Reck. The local HOA has decided not to take any action, unless more neighbors come to them.

North Carolina lawmakers say that banning clotheslines is not the right thing to do. But HOAs and housing businesses believe that clothesline drying reminds people of poor neighborhoods. They worry that if buyers think their future neighbors can't even afford dryers, housing prices will fall.

Environmentalists say such worries are not necessary, and in view of global warming, that idea needs to change. As they say, "The clothesline is beautiful. " Hanging clothes outside should be encouraged. We all have to do at least something to slow down the process of global warming.

8 . Today, getting information is as easy as opening a browser on your computer/phone, typing in a question and waiting a second for a long list of links to load. These websites will promise to answer your question. But actually, they may not be all that trustworthy. Figuring out which site is believable and which is false takes work. It isn’t impossible, though. Actually, it is what every good journalist (新闻记者) does daily. And students and other non-journalists also can do it.

To check a new claim (声明), good reporters contact experts on the topic. In journalism, such experts are known as “sources”. This may be a scientist who discovered something new in the lab. Or it could be the witness to a crime.

However, not everything is easy. For instance, if there’s a forest fire, how do you know where it started, when and how? You can ask government officials, but they may not know. You can talk to people near the fire shortly after it started. But unless someone spotted the fire as it happened, people may never know for sure. They may simply offer speculation. Saying something “might have” or even “probably” started that fire isn’t a fact. So you’d have to qualify any statement about the fire’s origins.

I describe such words as “weasel words”. These words and phrases include “might” “could have” “was likely to have been”, etc. Whenever something isn’t known for sure, journalists will highlight their uncertainty by using weasel words. They never over-blow claims to the readers.

A good reporter should be paid for the work he does. Some blogs and even news sites are authored by unpaid writers. Many of these writers are untrained in reporting, and their reports may not provide the depth. Thus, if the news you’re reading is free to the world online, consider what that may mean. Overall, you should be skeptical (怀疑的). That’s acting like a journalist.
