The answer to the question of how many years it takes to read a novel to be a bookworm varies from person to person. For some people, it may only take a few years to become a bookworm by reading novels, but for others, it may take longer. Generally speaking, to become a bookworm, one needed to have a certain level of reading ability and interest. If a person can easily read all kinds of novels and is interested in the plot, characters, and theme of the novel, then he may become a bookworm. The length of time did not determine whether a person would become a bookworm or not. What was important was his interest in novels and his reading ability.
