If you are hungry, what do you do? Have your favorite meal and stay quiet after that? __76__ But it never lets you know, because you keep it busy thinking about your friends or favorite stars. So it silently serves your needs and never lets itself grow. When mind loses its freedom to grow, creativity(创造力) gets a full stop. This might be the reason why we all sometimes think “ What happens next?”, “Why can’t I think?”

__77__ Why reading but not watching TV? It is because reading has been the most educative tool used by us right from childhood. Since it develops other aspects of our life, we have to take help from reading.

Once you read a book, you run your eyes through the lines and your mind tries to explain something to you. __78__ Now this seed(果实) is unknowingly used by you to develop new ideas. If it is used many times, the same seed can give you great help to relate(联系) a lot of things, which you would have never thought of in your wildest dreams!

This is nothing but creativity. __79__ Within no time you can start talking with your friends in English or any other language and never run out of the right words.

So guys, do give food for your thoughts by reading, reading and more reading. __80__ Go and get a book!

A．The interesting part of the book is stored(存储) in your mind as a seed.

B．Why not do some reading while you are hungry?

C．Just like your stomach, your mind is also hungry.

D．Now what are you waiting for?

E.Hunger of the mind can be actually solved through wide reading.

F.Reading can help you make more friends, too.
