Each year thousands of{#blank#}1{#/blank#} (explore) and tourists visit the polar regions of the Arctic and Antarctica. But the increasing number of people travelling to the ends of the Earth' can have a negative effect{#blank#}2{#/blank#} fragile ecosystems. Should tourists{#blank#}3{#/blank#}(allow) to visit polar regions?

    About 40,000 tourists visit Antarctica each year, More than five million travel to the Arctic and sub-Arctic. Transporting tourists to the regions {#blank#}4{#/blank#}(increase) ship and airplane traffic, adding to the risk of pollution, oil spills, and other {#blank#}5{#/blank#}(environment) damage. Because the places where wildlife is accessible {#blank#}6{#/blank#}(be) few in numbers, tourist traffic can become concentrated in specific areas,{#blank#}7{#/blank#} (put) Arctic vegetation at risk.

    Others say that access{#blank#}8{#/blank#} these very special parts of the world should not be restricted to only researches and scientist. Polar tourism allows people to develop deep personal connections with polar regions. “Those {#blank#}9{#/blank#}travel to the Arctic or Antarctica often become cheer leaders for supporting those places” Jim Sano, vice president for travel and{#blank#}10{#/blank#}(conserve) at World Wildlife Fund, told TFK.

    I never thought that little help would turn out to be the most satisfying thing I have ever done. He was tired, in pain and struggling to climb farther. With a broad smile, he asked me {#blank#}1{#/blank#} I could help him with some money. He was paralyzed(残疾)in both {#blank#}2{#/blank#}(leg) and was raising money for an operation. He said if doctors operated {#blank#}3{#/blank#} (success), he could attend a training for a job. I was full of doubts. I even asked him {#blank#}4{#/blank#} (show) his legs. In the end, I gave him some money. After a few days, he came back asking for more money. This time I was sure that he was cheating {#blank#}5{#/blank#}(I). However, I gave him some.

    A year later, I got a call from him. What he said was {#blank#}6{#/blank#} (move). He said the operation was successful and he had got a job. He wanted to return my money so that I wouldn't feel {#blank#}7{#/blank#} (cheat) and would continue to help people who are {#blank#}8{#/blank#} need in the future. I don't know whether he guessed my facial expression that day, but tears {#blank#}9{#/blank#} (run) down my face. That day I promised him I would continue to help people when I got an opportunity—small {#blank#}10{#/blank#} big.

    When I was a kid, Mom used to cook food for us. One night after {#blank#}1{#/blank#} (spend) a long hard day at work, Mom placed a plate of bread jam and {#blank#}2{#/blank#} (extreme) burnt toast（烤面包） in front of my dad, I was waiting {#blank#}3{#/blank#} (see) if he noticed it. However, while eating his toast. Dad just asked me {#blank#}4{#/blank#} my day was at school. I don't remember what I told him that night,{#blank#}5{#/blank#} I do remember I heard Mom apologizing to Dad for burning the toast. I'll never forget what Dad said, "Honey, I love burnt toast."

    Later that night, I {#blank#}6{#/blank#} (go) to kiss Daddy good night and asked him if he really liked his toast burned. He gave me {#blank#}7{#/blank#} big hug and said, "Your mamma put in a long hard day at work today, really {#blank#}8{#/blank#} (tire). Besides, a burnt toast never hurts but cold words do!"

    What I've learned over the years {#blank#}9{#/blank#} (be) that learning to accept each other's faults is one of the most important {#blank#}10{#/blank#} (key) to creating a healthy, growing and lasting relationship.
