Honesty is a virtue, and telling a lie is morally wrong. But how can you know if someone is {#blank#}1{#/blank#}? The answer is, they're probably not. Traditional economics says that people are rational beings who will lie if it is {#blank#}2{#/blank#} their advantage. A recent university study has shown that, actually, we're pretty honest ―especially {#blank#}3{#/blank#} we're at home.

Researchers in Germany phoned people at home and asked them to toss a coin. There was a strong financial incentive (激励) to fake the result: if the coin landed tails-up, the participant would receive money or a gift voucher, while if the coin landed heads-up, they would get {#blank#}4{#/blank#}. Because they were on the phone, they knew there was no {#blank#}5{#/blank#} of getting caught if they lied. And yet people revealed the truth despite that they {#blank#}6{#/blank#} (receive) nothing. Over hundreds of tosses a coin will land tails-up roughly 50% of the time. In this study over half the people (55.6%) asked said that the coin landed heads-up. Most of them didn't pursue the reward at the {#blank#}7{#/blank#} of honesty.

    Previous studies had found that people were more dishonest. In those laboratory studies 75% of people, {#blank#}8{#/blank#} (include) some who faked the results, reported a winning coin and claimed a reward. So the research team guesses it's being in our own home {#blank#}9{#/blank#} makes us play fair. {#blank#}10{#/blank#}, what motivates people to do so remains unclear.

    Well, today is the day. Microsoft is officially pulling the life support plug on Windows XP. And while the majority of PC user have {#blank#}1{#/blank#} (obvious) moved on to newer operating systems(OS）, some people stuck {#blank#}2{#/blank#} Windows XP over the last 12 years. As is reported by The Washington Post, {#blank#}3{#/blank#} enormous number of government machines are still running the old OS, {#blank#}4{#/blank#} could probably create a security problem.

    Clearly, over 13 percent of PCs in the United States are still running Windows Xp, {#blank#}5{#/blank#} Microsoft announced the end for support over two years ago. As many as 10 percent of US government computers, thousands of PCs holding sensitive information{#blank#}6{#/blank#} (include), will now be without{#blank#}7{#/blank#} (far) security updates.

    Yesterday, the Guardian reported the UK government has paid Microsoft 5.5 million pounds for a one-year {#blank#}8{#/blank#} (extend) of support. And if you think the problem is only at the desktop and notebook level, you can be quite wrong; don't forget as many as 60 percent of ATM machines in the US{#blank#}9{#/blank#} (be) still running XP.

    So, what's the solution? These business, government agencies and consumers will have to upgrade. And whether they choose Windows 7{#blank#}10{#/blank#} Windows 8, either is probably better than a security breach(漏洞）.

    At first my new {#blank#}1{#/blank#} were difficult to tolerate. The air seemed thin, as though  its combination of gases had little oxygen left.  Hit by a {#blank#}2{#/blank#} of fresh air, my head ached. Just as I tried to make the necessary {#blank#}3{#/blank#} to this new situation ,Wang ping handed a mask to me and I felt better in {#blank#}4{#/blank#} time. Soon I was {#blank#}5{#/blank#} on my feet again and following him to collect a hovering carriage driven by computer. Wang Ping fastened my safety belt and showed me how to use it. Soon I could fly as fast as him. However, I lost {#blank#}6{#/blank#} of him when we reached what looked like a large market because of too many carriage flying in all directions.

    During the Renaissance, new ideas and values gradually {#blank#}7{#/blank#} those held in the Middle Ages. People began to {#blank#}8{#/blank#} less on religious themes and adopt a more humanistic attitude to life. … Rich people wanted to {#blank#}9{#/blank#} their own paintings, so they could {#blank#}10{#/blank#} their superb palaces and great houses.

    More and more people live in large cities these days,{#blank#}1{#/blank#} means that it is becoming more and more difficult to find space and time for{#blank#}2{#/blank#} (we). But for many people, personal privacy (隐私) is very{#blank#}3{#/blank#} (importance). In many homes, a few minutes in the bathroom is all the privacy that is available.

    Teenagers especially need their own personal space{#blank#}4{#/blank#} home where they can feel relaxed and private. But, of course, not all teenagers{#blank#}5{#/blank#} (be) lucky enough to have a room of their own. Where space is short, they often have to share a bedroom {#blank#}6{#/blank#}a brother or sister. In that case, it's a good idea for them to have a special area or corner of the room to call their own. It is {#blank#}7{#/blank#} (similar) important for young people to have somewhere to keep their personal things. This may or may not be a tidy place and it is not a good idea for parents to try and tell teenagers how{#blank#}8{#/blank#}(organize) their space as this is likely to lead to{#blank#}9{#/blank#} (argue). Parents can, however, make sure that there are enough storage (存储) spaces{#blank#}10{#/blank#}as shelves, cupboard and boxes. This will allow the teenagers to keep their space tidy if they want to.

    I was always told that the three Ps, patience, positive thinking and perseverance, were a sure path{#blank#}1{#/blank#}success. But this piece of advice does not always work as planned. My high school math exam is one example. The exam， {#blank#}2{#/blank#} was originally to be held in our classroom, {#blank#}3{#/blank#}(change) to the library at the last minute. This, {#blank#}4{#/blank#}, didn't bother me because math had always been my strongest subject. I patiently walked to the library, took my seat and took a deep breath to help relax {#blank#}5{#/blank#}. But my mood quickly changed when I saw{#blank#}6{#/blank#}first question. I had no idea how to do it. I tried to stay positive and preserved{#blank#}7{#/blank#} I finally found the solution. With the problem{#blank#}8{#/blank#} (solve), I felt proud of my achievement. {#blank#}9{#/blank#} (fortunate), I then notice that I had just 10 minutes left {#blank#}10{#/blank#} (complete) the rest.
