Everyone has a childhood. And childhood {#blank#}1{#/blank#} (experience) are often very funny. Children often make us laugh. It's true that children brighten up a home. They never turn off the lights.

    I often recall my childhood, the years {#blank#}2{#/blank#} many interesting things happened. When I was a two-year-old child, {#blank#}3{#/blank#} my parents were always very busy with their work. My mother worked {#blank#}4{#/blank#} a sales manager in a company {#blank#}5{#/blank#} my father served in the army. So I lived with my grandma in a village. I was always waiting for my parents at home. Once my father sent us a photo of his {#blank#}6{#/blank#} (dress) in a soldier's uniform {#blank#}7{#/blank#} was posted on the table reminding me of him.

    Once my mother came to see me and we went {#blank#}8{#/blank#}(shop) together. On the way we saw a group of soldiers. And when I saw them, I became{#blank#}9{#/blank#} (excite). I said in a ringing voice pointing to {#blank#}10{#/blank#}, “This is my father, and this is my father, and that is my father, too!”

    My mother said she would remember that moment all her life.

    Long before Barack Obama became president of the United States, he wrote a book{#blank#}1{#/blank#}(call) Dream from My Father: A Story of Race and Inheritance, which has since become{#blank#}2{#/blank#}bestseller. It is an{#blank#}3{#/blank#}(appeal) book that includes what he went through during{#blank#}4{#/blank#}(he) childhood. Obama has little contact with his father{#blank#}5{#/blank#}roots were in Kenya because he left home when Obama was very young. His mother got married{#blank#}6{#/blank#}a student from Indonesia shortly after the family moved to Jakarta. A few years later, Obama came back with his grandparents to Hawaii, where he{#blank#}7{#/blank#}(attend) a private high school.{#blank#}8{#/blank#} (study) at Columbia in New York City, he then entered Harvard Law School. This autobiography also touches{#blank#}9{#/blank#}(heavy) on Obama's exposure to racism. Readers will find his reflections of childhood {#blank#}10{#/blank#}(experience) which involved racial discrimination to be especially moving.

    Climate change has caused a rise in sea levels. This has increased the amount of salt in fresh water{#blank#}1{#/blank#}(use) on coastal farms. As{#blank#}2{#/blank#} result, farmers are {#blank#}3{#/blank#}(gradual) unable to use fields close to the sea.

    However, Marc Van Rijsselberg, a farmer in the Netherlands is now using a{#blank#}4{#/blank#}(mix) of sea and fresh water {#blank#}5{#/blank#}(grow) healthy and tasty vegetables.

    He teamed up with scientists from the Free University and divided a farm {#blank#}6{#/blank#}eight negated areas. Separate pipes pumped fresh and sea water, and a computer program created water with eight levels of salinity（含盐度）．

    The water levels and the levels of salinity were controlled by computerized measuring devices called "sensors". Mr. Van Rijsselberg said he was able to harvest vegetables from most of the eight testing areas. He said the vegetables were smaller than {#blank#}7{#/blank#}grown in fresh water. But he said they also had more sugar and salt, so they tasted much{#blank#}8{#/blank#}(good).

    He found that potatoes grew better than the other vegetables in the combination of sea and fresh water. Mr. Van Rijsselberg said four kinds of these potatoes would be sent to Pakistan{#blank#}9{#/blank#}thousands of hectares of land {#blank#}10{#/blank#}(damage) by salinization (盐化作用) last year.

    Yesterday was a crazy day. I felt very tired {#blank#}1{#/blank#}I had a lot of work stuff going. Then I got {#blank#}2{#/blank#} message from one of my teammates. It said, “ We want to let you know that there are people who see and {#blank#}3{#/blank#}(true)appreciate all your hard work.” This meant more to {#blank#}4{#/blank#}(I)than anything else . And it made me think that maybe I need to set time aside{#blank#}5{#/blank#}(tell)the people in my life how much I appreciate what they did. Say “Thank you” {#blank#}6{#/blank#} the delivery guy, telling him that you appreciate how hard he {#blank#}7{#/blank#}(work); tell your daughter that you are proud of her {#blank#}8{#/blank#} (perform)at school; tell your mom that you notice how much she does for the family.

    Sometimes when a long time goes by without{#blank#}9{#/blank#}(recognize)for the good we do, we start to get upset, but a simple statement of appreciation could make us become{#blank#}10{#/blank#}(energy)again for a good long time.

    Students are busy. Between classes, work, homework and family, there can be a lot to balance. So why would we suggest that you add another thing to that list by {#blank#}1{#/blank#} (join) a student organization? First of all, it presents many opportunities to learn more about {#blank#}2{#/blank#} (you), your goals, and your strengths. You can also find out what you're good at, whether that's listening, staying organized, or serving others. This self-awareness {#blank#}3{#/blank#} (be) beneficial in your future career.
