This isn't as hard as it     7    (sound), and it is far better than any other method because you improve your vocabulary while     8    (read) an interesting piece of literature. Another nice thing is that you learn both new words and     9    (they) use unconsciously, meaning that you will tend to use the words     10    (learn) this way in conversations almost automatically.
