While {#blank#}1{#/blank#}(wait) for the airplane to take off,I was happy to get a seat by myself. Just then, {#blank#}2{#/blank#} air hostess approached me and asked,"Would you mind {#blank#}3{#/blank#}(change) your seat?A couple would like to sit together."The only possible seat was next to a girl with her arms in casts（石膏绷带）,a black and blue face,and a sad {#blank#}4{#/blank#}(express)."No way am I going to sit there,"I thought {#blank#}5{#/blank#}(immediate).But a soft voice spoke,"She needs help."Finally,I decided to move to that seat.The girl was named Kathy.She was hurt in a car accident and now was {#blank#}6{#/blank#}her way to treatment. When the snacks and juice arrived,it did not take me long to realize {#blank#}7{#/blank#}Kathy would not be able to feed herself.I considered {#blank#}8{#/blank#}necessary to feed her but hesitated,as it seemed too impolite to offer a service to a stranger.But then I realized that Kathy's need was more important than my discomfort.I offered {#blank#}9{#/blank#}(help) her eat, and although she was uncomfortable to accept,she did as I expected.We became closer and closer in a short period of time.By the end of the five-hour trip,we had become friends.Love sometimes flows beyond human borders and {#blank#}10{#/blank#}(remove) the tear that keeps us separate.When we offer to serve another,we grow to live in a larger and more rewarding world.

    The Great Wall was listed as a World Heritage by UNESCO in 1987. Just like a dragon, it winds up and down across deserts, grasslands and mountains, {#blank#}1{#/blank#} (run) approximately 21, 196 kilometers from east to west.

    The {#blank#}2{#/blank#} (construct) of the Great Wall was not that easy, {#blank#}3{#/blank#} drew heavily on the local resources for building materials. The walls were {#blank#}4{#/blank#} (origin) built in the Spring & Autumn Period and the Warring States Period. Emperor Qin Shi Huang succeeded in his effort to have them joined together. Since then, the Great Wall {#blank#}5{#/blank#} (serve) as a monument of the Chinese nation throughout history.

However, the Great Wall of China is still one of the most appealing {#blank#}8{#/blank#} (attraction) all around the world owing to its historical significance. The best-known part of the Great Wall of China, Badaling, {#blank#}9{#/blank#} (locate) 43 miles northwest of Beijing, attracts thousands of national and foreign tourists every day.
