3 . Easy Ways to Build Vocabulary

It's not all that hard to build an advanced and large vocabulary. Like many things in life, it's     1    ongoing process, and the best part of the process is that there's enough room for improvement,     2    means you'll just keep getting better and better. Of course you have to work at it. You wouldn't think that a few     3    (month) of exercise in your teens would be enough     4     the rest of your life, and that's also true for building your vocabulary--you have to keep at it daily, and pretty soon you will find that you have an excellent vocabulary.

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.
