Body language is one of the most powerful {#blank#}1{#/blank#}(mean) of communication, often even more powerful {#blank#}2{#/blank#}spoken language. People around the world show many kinds of feelings, wishes and attitudes that they might never speak aloud. {#blank#}3{#/blank#} is possible to "read" others around us, even if they do not intend for us to catch their {#blank#}4{#/blank#}(speak) communication. Of course, body language can be misread, {#blank#}5{#/blank#} many gestures and actions are universal.

    The most universal {#blank#}6{#/blank#}(face) expression is, of course, the smile- its function is to show happiness and put people at ease. It does not always mean that we are {#blank#}7{#/blank#}(true) happy, however. Smiles around the world can be false {#blank#}8{#/blank#}(hide) other feelings like anger, fear or worry. There are unhappy smiles, such as when someone" {#blank#}9{#/blank#}_ (lose) face" and smiles to hide it. However, the general purpose of smiling is to show good {#blank#}10{#/blank#} (feel).

    One night last February, a seventeen-year-old Duffy drove home along a winding road, he saw a strange light thrown against the tree. “I knew it wasn't the moon”, he said. “I drive this road all {#blank#}1{#/blank#}time and I notice little things out of place.”

    Duffy stopped his car and got out {#blank#}2{#/blank#}(examine). Below him far down in the deep valley lay a broken car with its headlights on. Thirty minutes earlier, a man had driven off the edge of the road, which has no guardrail(护栏). His car fell and rolled end over end, {#blank#}3{#/blank#}(land) on its top more than two hundred feet below.

    Duffy rushed to call for help, then returned and got down to reach the driver {#blank#}4{#/blank#}was badly injured. Snow covered the valley {#blank#}5{#/blank#}the temperature was below freezing. After struggling back up the cliff, Duffy took off his jacket and shirt and wrapped the man in time, along {#blank#}6{#/blank#} the blankets from his car.

    Life-saving {#blank#}7{#/blank#}(deed) are starting to become usual action for Duffy, the oldest of seven children. When he was 12, he saved his ten-year-old brother from drowning. Two years ago, his three-year-old sister {#blank#}8{#/blank#}(eat) rat poison, and Duffy {#blank#}9{#/blank#}(instant) cleaned out her mouth, make her drink milk to protect her stomach and called doctors.

    “We personal belief is that it is{#blank#}10{#/blank#}(meaning) for us to teach the children good values, and it looks like we have got some reward for it.” his father says.

    Today, home-ownership has reached extremely high levels. Modern generations tend to believe there is something wrong with them {#blank#}1{#/blank#} they rent. However, is high home-ownership really as people imagine？{#blank#}2{#/blank#} (stare) at data first, we realize that the most successful, stable, attractive country in the Western world is Switzerland. It has tiny unemployment; wealth; high happiness and mental-health scores. Does it have high home-ownership rates? Absolutely not. In Switzerland, about seven in ten of the population are renters. Yet, with Europe's {#blank#}3{#/blank#} (low) home-ownership rate, the nation thrives. Now go to the other end of the misery distribution. Spain has approximately the highest home-ownership rate in Europe (at more than 80%). But one-quarter of its population are unemployed.

    A likely reason is that high levels of home-ownership mess up the labour market. In a sensibly functioning economy it is easy for people to move around to drop into the vibrant job slots {#blank#}4{#/blank#} (throw) up by technological change. With a high degree of owner-occupation, everything slows. Folk get stuck. Renters can go to new jobs. In that way they do the economy a favours. {#blank#}5{#/blank#} Friedman said, the rate of unemployment depends on the flexibility of the housing market.

Next we come to economic breakdown. Most analysts accept that at heart it was the housing market-obsessive pursuit of homes, the engendered mortgage（房贷） lending and an unavoidable house-price crash— {#blank#}6{#/blank#} sank the Western world. Germany, say, with its more efficient rental market, had a far smoother ride through trouble.

    As for the monetary system, in the past few decades, in the hope of getting untaxed capital gains way above their true labour earnings, many people threw their spare cash into buying larger houses or building extra bedrooms. TV programmes about how to make easy money, beautiful rising house prices, and most importantly, our faulty tax system encouraged that. When {#blank#}7{#/blank#} some point market broke down, everyone suffered. Our countries ought, instead, to design tax systems that encourage people to invest in productive real activities and in innovation. Renting leaves money free for better purposes. That also points to the role of sensible budgeting over a person's lifetime. Why should we think that when we die it is necessary {#blank#}8{#/blank#} (pay) off an entire house？

    Our children do not deserve it. Let them pay for themselves. We {#blank#}9{#/blank#} rent-and enjoy our lives with the money saved.

    Finally, moderation usually pays off. Our scientific understanding of how economies function is horribly limited. This suggests that the golden rule should be to avoid extremes. A50-50mix of home-ownership and renting, not the 70-30split that is now observed in so many Western nations, {#blank#}10{#/blank#} (make) sense.
