Aristotle once wrote that “happiness is a state of activity”. In other words, whether you're seeking life-long satisfaction or a few moments of good cheer, you've got to move forward. We've interviewed the experts and found five steps to take toward a sunny mood（心情）：

    Over a 30-year period, University of Illinois researchers asked nearly 120, 000 people how income, education, political participation volunteer activities and close relationships affected their happiness. Reported Newsweek, s Sharon Begley on the findings, “The highest levels of happiness are found with the most stable and satisfying relationships. ”

    Singing aloud, talking to a stranger, raising your hand: all may increase a feeling of happiness, according to a study from Wake Forest University. Participants（参与者）followed the development of their moods for two weeks and reported feeling happier when they were more outgoing and less happy when reserved or withdrawn.

    The editors of forbes. Com gave $5 or $20 to 46 strangers by chance. Half the group was told to spend the money on themselves, while the other half was told to spend it on others. Those who'd shared the wealth felt much happier at the end of the day than those who'd spent it on themselves. There was no difference in happiness between those who spent $5 or $20, suggesting that it's not how much money you spend, but how you spend it, that inspires the spirit.

    Studies from the Positive Psychology Center showed that discouraged people who wrote down three good things that happened to them each day for six months reported an improved attitude.

    Drinking water really can help keep you cheerful. A small 2012 study from the University of Connecticut suggested that even slight dehydration（脱水） affected the moods of its female participants.

    It's 9 a.m.,the morning rush hour in Toronto.A man has fallen down on a downtown street suddenly.Several passers-by stop to help the man.One woman reaches into her purse for her cellphone and hits 911,the emergency number.{#blank#}1{#/blank#}

    Within ten minutes,the stricken man is in the back of an ambulance and is sent to the hospital for life-saving treatment.

This scene is fairly common in Toronto and other major cities.Over the years,cities have developed systems to respond quickly to emergencies{#blank#}2{#/blank#}But none of this would be possible without the cooperation of car drivers who yield（让路）to emergency vehicles on busy downtown streets.In fact,it's against the law for drivers not to yield.

    To yield means to give away or,more specifically,to get out of the way{#blank#}3{#/blank#}As yet,China doesn't have any specific laws that require drivers to yield,whether it is for slower cars to move over to the inside lane of a highway or for all cars to give way to emergency vehicles{#blank#}4{#/blank#}Drivers did not yield when they heard the ambulance's siren.

    In Canada,failing to yield to an ambulance vehicle can result in a fine of $400~$2,000 and reduction of three points off your license.That's for a first offense.

    {#blank#}5{#/blank#}This punishment is severe because lives are in danger.

    A.It has resulted in many lives being saved.

    B.A second offense results in a bigger fine,the loss of your driver's license for two years and a possible jail sentence.

    C.It saves lives and,who knows,someday it may save your own.

    D.Three minutes later,sirens（警报）are heard in the distance as a police car,an ambulance and a fire truck race to the area.

    E.It means pulling to the side of the road to let others pass.

    F.Recently,an injured Beijing cyclist died on the way to hospital because the ambulance carrying him got stuck in city traffic.

    G.Safe driving depends on driver's being aware of the traffic around them and yielding when necessary.

    Have you used “um…” “like…” “you know…” in your speech? Catch words(口头禅) are unnecessary words used to fill up dead paces while you speak. Speaking too many catch words is like a bad habit that we are unaware of. While most people tend to ignore it in everyday conversation, in a formal speech or an interview, too many catch words can make even the best presentation look bad.{#blank#}1{#/blank#}

    Stop when we are in doubt. Catch words are used more often when a person is unsure about the sentence to use next.{#blank#}2{#/blank#}If you are lost or in doubt over what to say next, just stop speaking, take a long pause, breathe in , figure out what to say and start again.

    Speak consciously and slowly. If the speech is too long and you talk continuously without thinking, then you might also be pushing in a few catch words in between.

    {#blank#}3{#/blank#}It is best to memorize the tricky parts of the speech, like the introduction and the conclusion where a majority of the catch words are used.

{#blank#}4{#/blank#} Preparing for the speech is very important when trying to remove catch words. Make it a point to pause when there is a comma or give two pauses at the end of the sentence. If certain words in the speech need to be emphasized then underline them and practice them as they need to be said.

    Avoid catch words in conversations. Get a friend or your partner to help you out when rehearsing a conversation.{#blank#}5{#/blank#} Although it can be an unpleasant and often embarrassing process, but in the long run it helps in cutting down on catch words.

A. Practise your speech when you can.

B. Remember the saying that silence is golden.

C. Therefore we can find out best friends to guide us well.

D. Anytime you use a catch word, the friend can point it out.

E. So we should learn some ways to avoid speaking such words.

F. Structure the speech well to include as much information as is needed.

G. The mind is so busy trying to figure out what to say that there is a strong urge to speak such words.

    Hobbies let you explore interests outside your work. {#blank#}1{#/blank#} There are plenty of options available to you. How can you choose the hobby that suits you from these options? Here are some tips.

    Look at what interests you. And examine what takes up your spare time, when you have it. Do you enjoy reading books? Maybe you want to try your hand at writing them. Do you like a cool beer at the end of the day? Maybe your hobby could be trying to make beer at home. {#blank#}2{#/blank#}

    Think about what you value most. What qualities do you think important? Do you value wisdom or courage? Do you admire artistic expression? {#blank#}3{#/blank#} For instance, maybe you could volunteer at a library as a hobby because you value education, or maybe you could take up painting because you admire people who can express themselves with art.

    {#blank#}4{#/blank#} Certain hobbies require certain skill sets. If you don't have much patience, then maybe hand sewing isn't something you'd enjoy. However, if you love building things, maybe you should consider a hobby like building furniture.

    {#blank#}5{#/blank#}Ask your friends and family what you seem to talk about the most. Now, think about what it is about that subject that you enjoy so much and determine how it can be turned into a hobby.

    Steel is a hard metal that people use to make many different products. Car bodies, bridges, building frames, and containers are just a few of the things made from steel. {#blank#}1{#/blank#} But steel is better than iron in many ways. Steel is stronger but lighter than iron. Steel also lasts longer than iron.

    {#blank#}2{#/blank#}Then they add carbon to the liquid iron. They may also add other materials to make different types of steel. For example, steel with added chromium（铬）is called stainless steel. It will not rust（生锈）or stain. Finally, workers use machines to cool the liquid steel into bars or long sheets.{#blank#}3{#/blank#}

    People made the first steel as early as 1400 BC. Ancient people heated iron inside a pile of burning charcoal（木炭）. {#blank#}4{#/blank#}. The result was not the same as modern steel, but it was stronger than regular iron.

    In the 1800s people began to use huge ovens to make large amounts of steel. In the late 1800s builders used steel to make some of the first skyscrapers. {#blank#}5{#/blank#}. In the 1900s new processes made steel-making easier. Today steel remains one of the most popular building materials in the world.

A. This added carbon to the iron.

B. Steel is quite different from iron.

C. The hardened steel may then be made into products.

D. Steel is basically iron mixed with a little carbon.

E. Then they will be cooled and put on the market.

F. To make steel, workers hear iron until it melts.

G. They also used steel to make large, modern bridges.

The urge to share our lives on social media

    People have long used media to see reflections of themselves. Long before mobile phones or even photography, diaries were kept as a way to understand oneself and the world in which one lives. In the 18th and 19th centuries, as diaries became more popular, middle-class New Englanders, particularly white women, wrote about their everyday lives and the world around them.

    These diaries were not a place into which they poured their innermost thoughts and desires, but rather a place to chronicle (记录) the social world around them. The diaries captured the everyday routines of mid-19th-century life, and women diarists in particular focused not on themselves but on their families and their communities.

Diaries today are, for the most part, private. But things were different for these New England diaries. Young women who were married would send their diaries home to their parents as a way of maintaining kin (血缘) relations. When family or friends came to visit, it was not uncommon to sit down and go through one's journal together.

    Diaries are not the only media that people have used to document lives and share them with others. We have long used media like photo albums, baby books and even slide shows as a means of creating traces (痕迹) of our lives. We do this to understand ourselves and to see trends in our behaviour. We create traces as part of our identity and part of our memory.

    Sharing everyday life events can strengthen social connection and intimacy (亲密感). For example, you take a picture of your child's first birthday. It is not only a developmental milestone: the photo also strengthen the identity of the family unit itself. The act of taking the photo and proudly sharing it further reaffirms (再次证实) one as a good and attentive parent. In other words, the media traces of others figure in our own identities.

    Today's social media platforms are, by and large, free to use, unlike historical diaries, which people had to buy. Today, advertising subsidises (补贴) our use of networked platforms. Therefore these platforms encourage use of their networks to build larger audiences and to better target them. Our pictures, our posts, and our likes are commodified—that is, they are used to create value through increasingly targeted advertising.

    Instead of social media merely connecting us, it has become a craze (狂热) for information, continually trying to draw us in with the promise of social connectivity—it's someone's birthday, someone liked your picture, etc. There's a multibillion-dollar industry pulling us into our smartphones, relying on a longstanding human need for communication.

    The urge to be present on social media is much more complex than simply narcissism (自恋).

    Social media of all kinds not only enable people to see their reflections, but to feel their connection as well.
