As the audience got larger, thetechnology got better. Television sets became more reliable through the 1960s. The reception (接收效果)improved. The picture improved. The major networks started broadcastingprograms in color.

    Even greater improvements were comingaccording to Sanford Brown, who wrote an article for the Post in 1967.Surprisingly, just about every prediction he made in the article became areality. For example: All sets in the not-distant future will be colorinstruments. He also predicted that TV sets would become smaller, simpler, morereliable and less expensive and may forever put the TV repairman out of work.Smaller sets do not, of course, mean smaller screens. TV engineers expectscreens to get much bigger. However, today's 3-D TV is even farther away, if it's coming at all. There is some doubt whether the public would be eager topay for it, in view of people's cold reception given to 3-D movies.

    But the technology with the greatestpotential, according to Brown, was cable television (有线电视), whichwas still in its early stages then. As he predicted, the future of cabletelevision was highly interactive (互动的). It wasn't cable television that gaveAmericans their electronic connection to the world, however. It was theInternet. He even foresaw the future office: using picture phones, big-screentelevisions for conferences, and computers providing information at the touchof a button.

    Brown ever said, “The future oftelevision is no longer a question of what we can invent. It's a question ofwhat we want.”

    If a stranger offered you money to keep a suitcase in your spare room，would you accept? How about the other way round：if you had too many belongings，would you consider trusting someone you met online with their safekeeping? Anthony Paine believed enough of us would answer “yes” to these questions to launch his own startup(新兴公司)，Stashbee．His business links people with space to those who need it．

    And it's just one player in the booming “sharing economy”，an industry that relies on people renting out things like their beds，bikes and even parking spaces．Airbnb，a company valued at 200bn RMB，provides a platform for those renting property short-term．DogVacay pairs holidaymaking pet owners with pet-friendly hosts，and aims to be profitable by 2017．

    All their business models revolve around one simple word：trust．So，how does Stashbee measure up? BBC journalist Dougal Shaw decided to try it out for himself．He had some odds and ends to store while renovating his house，and met a host through the site who could keep them for 475 RMB for two months．All relatively smooth and painless．

    Heavyweights(行业巨头)in the traditional storage industry，such as Big Yenow and Access，aren't convinced．A representative from Access told Shaw he was skeptical about storing with “amateurs”．He considered 24／7(全天候) access to the items and better security as the main advantages of his service.

    Stashbee agree that dealing with security concerns is important，but say business success depends more on people overcoming a distrust of strangers we've been taught since childhood. They aren't alone．Companies such as Costockage，Roost and Spacer all run similar storage businesses，and are all relying on a shift in consumer attitudes．

    And the concept of social storage doesn't stop there．CityStasher believe there's a gap in the market for those who want to store things for extremely short periods of time．

    Would you try it out? It's a question of trust．

Ways to make a great first impression

    You've heard it a million times already, but it really does take but a few seconds to make that all-important first impression (印象). Here are some easy ways for you to impress your classmates or teachers.

    {#blank#}1{#/blank#}

    Before you shake hands with somebody, make sure that your hands are clean. The handshake should not be too strong or weak. Most people use their right hands, unless they have a reason to use the left. {#blank#}2{#/blank#}

    Be on time

    When meeting someone for the first time, arriving on time is as important as breathing. You may have an excuse, but that will leave the person who hardly knows you with a bad impression. {#blank#}3{#/blank#} It's better to be hanging around the place than be stuck in traffic.

    Introduce yourself and ask for names

    Make sure you properly introduce yourself. Ask for their name in a polite way.  {#blank#}4{#/blank#} This will increase the chances of their remembering your name in the future. Always remember to stand up when greeting someone and be sure to introduce them to anyone you're with.

    Make good conversation

    To get the most out of your discussion, try to find something common between the two of you. {#blank#}5{#/blank#} A person will feel more comfortable with someone they can relate to (产生共鸣).

A. Use body language

B. Have a proper handshake

C. Repeat the name and use it later in conversation.

D. As a general rule, plan to arrive about 30 minutes early.

E. It could be a similar(相似的) taste in clothes or a common hobby.

F. You'll be in serious trouble if you leave them with a bad impression.

G. However, don't have your left hand in your pocket because this appears impolite.

    Why do we dream? It's a question researchers have been studying for years. Now new research suggests that some dreams may result from the brain's effort to keep learning, even as we sleep.

In a study in Boston,100 volunteers were trained for an hour on a maze(迷宫). They tried to find their way through the difficult puzzle as quickly as possible. Then half of the volunteers were allowed to sleep for 90 minutes. The other half stayed awake, reading or relaxing. The ones who slept were asked to describe their dreams when they woke up.

    After the rest, the volunteers were asked again to solve the maze. Those who hadn't slept showed no improvement or did even worse after the break. Sleepers who didn't report any maze­related dreams did better but showed only a little improvement. However, four nap­takers who reported dreaming about the maze showed a surprising improvement. They scored 10 times higher after sleeping and dreaming about the maze.

    Even though the number of dreamers was small, the researchers noted that the gap in learning between the dreamers and non­dreamers was so wide that the finding was significant(有意义的).

The dreamers had all performed poorly on the test before dreaming about it. That suggests that struggling with a task might be the trigger that leads the sleeping brain to focus on it and work on how to deal with it.

    "It's almost as if your brain is going through everything that happened today," Dr Stickgold, a scientist at Harvard Medical School, said. "The things you're obsessed(迷住) with are the ones that your brain forces you to continue to do with."

    If you wear glasses, chances are you are smarter. Research published in the famous British journal Nature Communications has found that people who displayed higher levels of intelligence were almost 30 percent more likely to wear glasses.

    The scientists studied the genes of thousands of people between the ages of 16 and 102.The study showed intelligence can be connected to physical characteristics. One characteristic was eyesight. In out of 10 people who were more intelligent, there was a higher chance they needed glasses. Scientists also said being smarter has other benefits. It is connected to better health.

    It is important to remember these are connections which are not proven causes. Scientists call this correlation. Just because something is connected to something else does not mean one of those things caused the other. And it's worth noting that what constitutes intelligence is subjective and can be difficult, if not impossible, to measure.

    Forget genes though. Plenty of proof shows wearing glasses makes people think you are more intelligent, even if you do not need glasses. A number of studies have found people who wear glasses are seen as smarter, hard-working and honest. Many lawyers use this idea to help win their cases. Lawyer Harvey Solves explained this. Glasses soften their appearance. He said sometimes there has been a huge amount of proof showing that people he was defending broke the law. He had them wear glasses and they weren't found guilty.

    Glasses are also used to show someone is intelligent in movies and on TV. Ideas about people who wear glasses have begun to shift. People who do not need glasses sometimes wear them for fashion only. They want to look worldly or cool. But not everyone is impressed by this idea, though. GQ magazine said people who wear glasses for fashion are trying too hard to look smart and hip (时髦的). However, that hasn't stopped many celebrities from happily wearing glasses even if they do not need them. Justin Bieber is just one high-profile fan of fashion glasses.

In life, once on a path, we tend to follow it, for better or worse. What's sad is that even if it's the latter, we often accept it anyway because we are so used to the way things are that we don't even recognize that they could be different. This is a phenomenon psychologist call functional fixedness.

This classic experiment will give you an idea of how it works and a sense of whether you may have fallen into the same trap: People are given a box of tacks (大头钉) and some matches and asked to find a way to attach a candle to a wall so that it burns properly.

Typically, the subjects try tacking the candle to the wall or lighting it to fix it with melted wax. The psychologists had, of course, arranged it so that neither of these obvious approaches would work. The tacks are too short, and the paraffin (石蜡) doesn't stick to the wall. So how can you complete the task? The successful technique is to use the tack box as a candle-holder. You empty it, tack it to the wall. and stand the candle inside it. To think of that, you have to look beyond the box's usual role as a receptacle just for tacks and re-imagine it serving an entirely new purpose. That is difficult because we all suffer to one degree or another from functional fixedness.

The inability to think in new ways affects people in every corner of society. The political theorist Hannah Arendt coined the phrase" frozen thoughts" to describe deeply held ideas that we no longer question but should. In Arendt's eyes, the self- content reliance on such accepted "truths" also made people blind to ideas that didn't fit their worldview, even when there was plenty of evidence for them.

Frozen thinking has nothing to do with intelligence. She said," It can be found in highly intelligent people."
