【题目】阅读理解
阅读下列短文，从每题所给的四个选项（A、B、C和D）中，选出最佳选项。
Charles Dickens (1812—1870), the great nineteenth century English novelist, was born near Portsmouth. His father ran heavily into debt (债) and when he was twelve, he had to go and work in a factory. The only formal education he received was a two-year schooling at a school for poor children. In fact, he had to teach himself all he knew. He worked for a time in a lawyer’s office. After that, he worked as a reporter in the law courts, and later for London newspapers. His life as a writer of novels began in 1833 with short stories and essays in newspapers, and in 1837 his novel “The Pickwick Papers” made him the most popular author at his time in England.

Many of his novels like “Oliver Twist”, “David Copperfield”, “Nicholas Nickleby”, “Great Expectations”, “A Tale of Two Cities” and so on drew attention to the unfair social conditions that existed in England over a hundred years ago.
