I had my first job at the age of thirteen, when a friend of my mother’s who owned a bookshop _36 me for six hours a week to help her in the shop. I was very   37 to earn my own pocket money and my parents   38 interfered(干涉) with how I spent it, even when I was spending it   39 . They believed that by earning money, spending it, and learning from the   40 , I would become more mature(成熟) and  41 about how to handle work, relationships with others, and money.
Like many   42 parents, my parents also let me and my brothers do things over which they  43  a great deal. When I was sixteen, for example, after I finished high school and before I entered university, I wanted to spend the summer months traveling around   44 . My mother was against the idea of my traveling alone at such a young age, but my father felt that it would be a great   45 for me. In the end, my father won the   46 on the condition that I limited my traveling to France, my mother’s home, where I had many uncles, aunts and cousins   47 through the country who could   48 shelter and help if I need them.
Three years later, my younger brother decide to   49 a year off after his first year in university and travel through the United States and the Caribbean. Again my mother was very worried and not   50 to see my brother leave school, but my father encouraged him and my brother had a(n)   51 year working his way on trains and ships to   52 passage to different ports and cities, and discovering many fascinating places and people.
These kinds of experiences are probably rare(稀少的) for children in many countries but in the US they are fairly   53 . Most parents start   54 their children at a young age to do small things by themselves. By the time they have finished high school, many American kids have already had part-time jobs, traveled around the US or other countries on their own, have   55 the university they plan to attend and maybe even decided on their future career, and so on.

Ibrahim became disabled after contracting polio (小儿麻痹症) when he was three years old. At first his parents, like many other parents of disabled children in Niger, did not want to send him to school. They were worried he would be laughed at by his classmates.  
Despite his disability, and his parents’ doubts, Ibrahim was determined to go to school. “When I was eight,” Ibrahim says, “other kids of my age were going to school while I stayed at home. I did not like that. So, I pestered (缠着) my parents until they finally let me go to school.”
Ibrahim’s parents sent him to a private school nearby. Although the journey to and from school was a short one, it still wasn’t easy for Ibrahim. He had to use his hands to help him move along, protecting them with plastic slippers. But at least he was getting an education.
However, after only a year in school, Ibrahim’s education was interrupted when his parents separated. His mother did not have the means to continue paying for his tuition.
In 2007, Ibrahim received some money to be fitted with a leg brace (支架), corrective shoes and his first pair of crutches (拐杖). Now that he was more mobile than before, the most important thing for him was to find a way to go back to school. 
“I wanted to start school again last October,” Ibrahim says. “After my mother told me she could not afford it, I went to visit some of my relatives for support. And I collected 5,000 francs CFA (US $8) to pay my tuition for half a year. I will find the rest of the money somehow.”
Ibrahim attends a school in which he is the only disabled student. According to his teacher, he is among the top five students in a class of 55.
