Mary is a student. She enjoys {#blank#}1{#/blank#}(run). Every morning, she starts to run near her home{#blank#}2{#/blank#} (介词) six o'clock. She also {#blank#}3{#/blank#} (like) ball games. After school, she {#blank#}4{#/blank#} (join) her classmates to play basketball. She {#blank#}5{#/blank#} (eat) well too. She has three {#blank#}6{#/blank#} (meal) at school. Her favourite food is {#blank#}7{#/blank#}(dumpling). But the dining hall is small with only ten {#blank#}8{#/blank#} (table). The students are always {#blank#}9{#/blank#}(wait) there. Now it's time for dinner. Mary is {#blank#}10{#/blank#} (walk) to the dining hall.

    From an early age, Parker always said that he would be an astronaut. But no matter {#blank#}1{#/blank#}much he studied, worked, and took tests, he never passed. Finally, he {#blank#}2{#/blank#} (grow) over the maximum(最高的) age for taking the test. He would never be able to realize his dream.

    People {#blank#}3{#/blank#} ( feel )sorry for his dream. Although he{#blank#}4{#/blank#} (tell) about having to give up his dream, Parker continued training and studying, as though he was going to sit the tests next month.

    He carried this on as he got {#blank#}5{#/blank#} (old), and when he was a very old man he heard that they were doing some very important medical experiments. For those experiments they needed {#blank#}6{#/blank#} very old astronaut. Parker, who now walked with a stick, was the only old man in the whole world who was trained to fly in a rocket.

    So Parker found {#blank#}7{#/blank#}(he) flying in space at last. The experiments were very {#blank#}8{#/blank#} (succeed). The knowledge from the experiments helped doctors to cure one of the {#blank#}9{#/blank#}(bad)sicknesses for old people, and Parker was celebrated as a hero. Photos of the astronaut with a walking stick and no{#blank#}10{#/blank#} (tooth) spread all over the world. It showed  that persistent effort always brings reward, even though that reward may not be in the form we had first expected.
