[单项选择]
Jim was born after his elder brother and sister. He could learn many things from them. Soon, he developed his own way of doing things by developing his mind through his interest in creating stories. He read more than most children and he gathered his inspiration from history books. In school, his athletic interests were basketball and bike, especially high jump. When he found he could jump a little higher than most students, he decided that jumping over a high bar would be his specialty.
Jim continued his learning interest in history which included serious college study, and a Master’s degree. He is now a university professor at a small university. In the United States there are many schools that have history departments. There are large universities with as many as 60 thousand students and small universities with as few as 2 000 students.
