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.

    Few people would even think of beginning a new job at the age of 76, {#blank#}1{#/blank#} one of America's most famous artists did just that. Anna Mary Robertson, better known as "Grandma Moses", turned to painting {#blank#}2{#/blank#} she was too old to work on her farm.

    Grandma Moses was crazy about painting soon after she picked it up and worked hard at it. She painted{#blank#}3{#/blank#} (care) and her works were nice .She first painted only to please {#blank#}4{#/blank#} (she),and then began to sell her works {#blank#}5{#/blank#} a little money. In 1993,a collector, Louis Caldor, happened to see several of Grandma Moses' works {#blank#}6{#/blank#} (hang) in a shop. He liked them {#blank#}7{#/blank#} (buy) them at once, and set out to look for {#blank#}8{#/blank#} (much).Caldor held {#blank#}9{#/blank#} show to introduce the works of Grandma Moses to other artists. Grandma Moses, {#blank#}10{#/blank#} was world-famous ,died on December 13, 1961,at the age of 101.

    Earth Day is an event {#blank#}1{#/blank#} (annual) celebrated on April 22.{#blank#}2{#/blank#} (found) by Senator Gaylord Nelson, an American politician and environmentalist, it was originally aimed at helping the public to know the current situation of pollution and {#blank#}3{#/blank#} (get) people to care about the earth.

    In 1962, Rachel Carson's bestseller “Silent Spring” created an {#blank#}4{#/blank#} (aware) of the dangerous effects of pesticides(农药）. Then, a fire,{#blank#}5{#/blank#}broke out in 1969 on Cleveland's Guyahoga River, revealed the problem of chemical pollution in water. Senator Gaylord Nelson dreamed of{#blank#}6{#/blank#}similar event that would get people to take environmental issues seriously. In 1969, he was inspired by protests against the Vietnam War and came up with the idea for Earth Day.

    In the fall of 1969, Nelson announced it and appealed to the entire country to get involved. Consequently, telegrams, letters and telephone calls {#blank#}7{#/blank#} all over the country poured in. Since 1970, Earth Day celebrations have grown. Later, Nelson{#blank#}8{#/blank#}(award) the Presidential Medal of Freedom because of his work.

    Today, numerous communities celebrate Earth Week, an entire week of{#blank#}9{#/blank#}(activity) focused on the environmental issues. In 2017, the March for Science {#blank#}10{#/blank#}(occur) on Earth Day and was followed by the People's Climate Mobilization on April 29.

    In a recent survey, 19 percent of teenagers said they had posted a comment online that they later regretted. The problem is that once something {#blank#}1{#/blank#}(put) on the Internet, it can be difficult to remove. Even if you're able to do so, someone else {#blank#}2{#/blank#}(probable)has already taken a picture your post. In addition, the content{#blank#}3{#/blank#}(delete)from a Webpage can often be recovered.

    Posting negative comments or images online is certainly best avoided, {#blank#}4{#/blank#} that's not the only thing you should consider when it comes to your online behavior. Experts say it's also important for young people {#blank#}5{#/blank#} (earn) a positive Internet reputation. You can do this by sharing positive content about the things you're most interested{#blank#}6{#/blank#}. This way, if someone {#blank#}7{#/blank#}(run)a search on you, the results will show them the content you most want them to see.

    Managing an online reputation can be {#blank#}8{#/blank#} (challenge). Remember that privacy settings can be very helpful for this, so use {#blank#}9{#/blank#}(they)if they're available. But most importantly, be careful about{#blank#}10{#/blank#} you share-your future may depend on it.

    Today I will introduce some new teachers in our class. Mrs. Li is my English teacher. My first {#blank#}1{#/blank#}(impress) of her was that she was nervous and shy. But now, I find she's kind and patient, who explains grammar {#blank#}2{#/blank#}(clear). I've always hated making mistakes or {#blank#}3{#/blank#}(pronounce) a word incorrectly when I speak English, but she just smiles, {#blank#}4{#/blank#}makes me feel easy.

    {#blank#}5{#/blank#}(Be) almost sixty, Mrs. Chen is {#blank#}6{#/blank#}experienced physics teacher, but she is very strict. All of us are afraid of her, and no one dare to be late for her lessons. Some of our class don't like her, but most of us really appreciate her because her teaching is so well {#blank#}7{#/blank#}(organise) and clear. I believe I'll do well in the exam with Mrs. Chen {#blank#}8{#/blank#}(teach) me.

    Another teacher I will mention below is Mr. Wu. He teaches us Chinese. He is popular among us because he really enjoys teaching Chinese literature. He becomes so energetic and humorous when he thinks we're getting {#blank#}9{#/blank#}(bore). Even things like compositions and {#blank#}10{#/blank#} (summary) are fun with him. I respect him a lot.
