根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。

     If you are hungry, what do you do? Have your favorite meal and stay quiet after that.__1__   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 gets a full

stop. This might be the reason why we all sometimes think "What happens next?", "Why can't I think?"

     __2__   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 get help from

reading.

     Once you read a book, you run your eyes through the lines and your mind tries to explain something to you. __3__  Now this seed 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 a lot of things which you would have never thought of in your

wildest dreams!

     This is nothing but creativity.  __4__   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. __5__  Go and get a

book!

A. The interesting part of the book is stored 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.

G. Also this makes a significant contribution to your vocabulary
