A professor stood before his class of twenty senior organic biology students and was about to hand {#blank#}1{#/blank#} the final exam papers.

    “I want to say that {#blank#}2{#/blank#}has been a pleasure teaching you this term. I know you've worked {#blank#}3{#/blank#}(extreme) hard and many of you are off to medical school after summer. I know no one wants to get their GPA(平均成绩){#blank#}4{#/blank#} (mess) up because they might have been celebrating this week. Anyone who prefers not to take the final exam today {#blank#}5{#/blank#}(receive) a 'B' for the course.”

    The students were filled with {#blank#}6{#/blank#}(happy) as they got up, walked to the front of the class, and accepted the professor's offer. As {#blank#}7{#/blank#}last taker left the room, the professor looked at the handful of {#blank#}8{#/blank#}(remain) students and asked, “Anyone else? This is your last chance.”

    One final student rose up and chose not to take part in the final. The professor closed the door and checked who were still in the classroom.

    “I'm glad to see you believe in {#blank#}9{#/blank#}(you),” he said. “You all get 'A's.”

    How many have taken the easy way out? The short road, the easy path {#blank#}10{#/blank#}the light load all lead to lower grades in school of 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.

    Benjamin West, the father of American painting, showed his talent for art when he was only six years of age. But he did not know about brushes before {#blank#}1{#/blank#} visitor told him he needed one. In those days, a brush was made from camel's hair. There were no camels nearby. Benjamin decided that cat hair would work instead. He cut some fur from the family cat {#blank#}2{#/blank#} (make) a brush.

    The brush did not last long. Soon Benjamin needed more fur. Before long, the cat began to look ragged(蓬乱). His father said that the cat {#blank#}3{#/blank#} be sick. Benjamin {#blank#}4{#/blank#} (force) to admit what he had been doing.

    The cat's lot was about to improve. That year, one of Benjamin's cousins, Mr. Pennington, came to visit. He was impressed with Benjamin's drawings. {#blank#}5{#/blank#} he went home, he sent Benjamin a box for paint and some brushes. He also sent six engravings(版画)by an artist. {#blank#}6{#/blank#} were the first pictures and first real paint and brushes Benjamin had even seen. In 1747, when Benjamin was nine years old, Mr. Pennington returned for another visit. He was amazed at {#blank#}7{#/blank#} Benjamin had done with his gift. He asked Benjamin's parents {#blank#}8{#/blank#} he might take the boy to Philadelphia for a visit.

    In the city, Mr. Pennington gave Benjamin materials for creating oil paintings. The boy began a landscape painting. William Williams, a well-known painter, came to see him work. Williams was impressed with Benjamin and gave him two classic books on painting to take home. The books were long and dull. Benjamin could read only a little, {#blank#}9{#/blank#} (be) a poor student. But he later said, “Those two books were my companions by day, and {#blank#}10{#/blank#} my pillow at night." While it is likely that he understood very little of the books, they were his introduction to classical paintings. The nine-year-old boy decided then that he would be an artist.
