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.

    Life is filled with regrets(遗憾). Anyone around you will have no difficulty {#blank#}1{#/blank#} (tell)his regrets. As we get older, we look back and wish that we{#blank#}2{#/blank#}(make)better choices.{#blank#}3{#/blank#}can we do to avoid future regrets?

    Make better plans. The{#blank#}4{#/blank#}(early), the better. You will know that comes first and what comes last. You'll also know what you should do and what you shouldn't do. If changed happen, you can have more time to deal with them.

    Live a more active life. More outdoor{#blank#}5{#/blank#}(active) can keep you relaxed and active. You also need to be kind. “Thank you” can bring a smile to someone's face. Learn to say “sorry” and don't be angry {#blank#}6{#/blank#}others.

    Find the right friend. When you get into trouble, ask {#blank#}7{#/blank#}(other) for help. That little help may get you good results.

    It's{#blank#}8{#/blank#}(general) believed that everybody fails, even the greatest person failed. So we must consider failure as{#blank#}9{#/blank#}chance to learn and improve ourselves.

    Life is good. We don't have to live in our past, but we do hope that we can plan better, live better,{#blank#}10{#/blank#}work better when we have the chance to do so.
