61．阅读下面材料，根据其内容和所给段落开头语续写两段，使之构成一篇完整的短文
Ali and his younger sister, Zahra, lived with their parents in a poor neighborhood. Their mother was very sick and their father was struggling to find a job, and they had only a little money with which to buy food. As they had not paid the rent for several months, the landlord was breathing down their necks (催促).
One day, Ali took Zahra’s shoes to a shoe repairman to be fixed, but he lost them on the way home. It wasn’t until he got home that he realized he had lost the shoes. He was afraid that his parents would be angry and disappointed, so he begged his sister to keep it secret. Zahra agreed and the two decided to share Ali’s running shoes. Zahra’s school hours were in the morning, so she would wear them first. After school, she would rush back and give them to Ali. He could then run to his school, which began in the afternoon. Although he ran as fast as he could, Ali often arrived late and was warned by the school.
Ali heard about a long distance race that was held for the boys in the city. When he learned that the third prize was a new pair of shoes, he decided to take part. He ran home excitedly and promised his sister that he would win her the new shoes.
The day of race arrived. Ali had a strong start, but halfway through the race he began to get tired and his legs began to ache. Getting more and more exhausted he thought only of Zahra and his promise to her. Dreaming of the new shoes he would win for his sister gave him strength, and he stayed right behind the two fastest runners, determined to finish third. Suddenly, as the finish line drew near, another runner collided (碰撞) with Ali from behind and he crashed to the ground.
