阅读下面短文，根据所给情节进行续写，使之构成一个完整的故事。
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(盯着他们).
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.
