A researcher has made a report {#blank#}1{#/blank#} says having a lot of money makes you a bad person. Professor Paul Piff spent ten years {#blank#}2{#/blank#} (look) at the personalities of rich people and {#blank#}3{#/blank#} (find) that their behaviour was very different {#blank#}4{#/blank#} the behavior of poor people. Rich people are more likely to break {#blank#}5{#/blank#} (rule), not follow the law, and not care about other people. Wealthy people cheat more at games and are less likely to help other people. Professor Piff told the BBC, “Wealth makes you more {#blank#}6{#/blank#} (worry) about your own interests, your own desires, your own welfare.” He added that rich people think their own goals and needs are the most {#blank#}7{#/blank#} (importance) thing in their life.

    Professor Piff also found that poor people are more generous than rich people. The poor give a higher percentage of their money {#blank#}8{#/blank#} (help) others than the rich. The {#blank#}9{#/blank#} (wealth) you are, the less generous you are. You give significantly smaller portions away to other people. However, he said that rich people could change their behavior and become nicer {#blank#}10{#/blank#} more generous.

    Linda Evans was my best friend. When I was 13, my family moved away. We kept in touch through {#blank#}1{#/blank#} (letter) and saw each other on special time — like my wedding and Linda's. Soon we were busy with children and {#blank#}2{#/blank#} (move) to new homes, and we wrote less often. One day a card that I sent {#blank#}3{#/blank#} (come) back, stamped—Address Unknown. We lost touch with each other.

    Over the years, I missed Linda very much. I was eager {#blank#}4{#/blank#} (share) happiness and sadness. There was {#blank#}5{#/blank#} empty place in my heart that only a friend like Linda could fill.

    One day, I {#blank#}6{#/blank#} (read) a newspaper when I noticed a photo of a young woman who looked very much like Linda and whose last name was Wagman—Linda's {#blank#}7{#/blank#} (marry) name. There must be thousands of Wagmans, I thought, {#blank#}8{#/blank#} I still wrote to her.

    She called as soon as she got my letter. Mrs, Tobin, she said {#blank#}9{#/blank#} (excite), —Linda Evans Wagman is my mother.

    Minutes later, I heard a voice that I knew very much, even {#blank#}10{#/blank#} 40 years. Now the empty place in my heart is filled. And there's one thing that Linda and I know for sure: we won't lose each other again!

    NASA has a new job listing, and it's no joke. The US space agency is looking for a "joker" to join their {#blank#}1{#/blank#} (plan) mission to Mars.

A mission to Mars is no laughing matter. {#blank#}2{#/blank#} is known that Mars is 225 million kilometers away from Earth. A trip there would take around eight months in a small spacecraft. "When you're living with others in a confined (封闭的) space for a long period of time, such as on a mission to Mars, problems are likely {#blank#}3{#/blank#} (happen)" Jeffrey Johnson, a scientist at the University of Florida, {#blank#}4{#/blank#} (say) to the Guardian. This is probably {#blank#}5{#/blank#} NASA wants an astronaut with a sense of humor. "These are people that have the {#blank#}6{#/blank#} (able) to pull everyone together." Johnson said.

    In {#blank#}7{#/blank#} (stress) situations, perhaps humor is a way to know we aren't alone. We can share our stress by {#blank#}8{#/blank#} (laugh) together. Then we can focus on our jobs instead of just worrying.

But if you're hoping that your favorite TV comedian will fly to Mars, that {#blank#}9{#/blank#} (possible) won't happen. "Being funny won't be enough to land somebody the job," Johnson said, "They also need to be an excellent scientist and engineer." Besides, it's required that they {#blank#}10{#/blank#} (be) in top physical condition.
