    If you want to get the most out of the study of a language, you must also read for pleasure: novels, plays, travel books, and so on. And in reading books of this kind thething is to get on with the reading, to try to grasp(领会)the writer is going to tell you in the book as a whole. This is impossible if you stop and think over theof every single word which happens to be unfamiliar. You cannot enjoy a story if you stop lots of times on every page forwords in the dictionary. You may even prevent yourself from understanding the story as a whole by doing this.
