If you are hungry, what do you do? Have your favorite-meal and stay quiet after that?_ 71 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 sets a full stop．This might be the reason why we all sometimes think "What happens next?", "Why can't I think?"72 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．73 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．74 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．75 Go and get a book!A．Now what are you waiting for?B．Reading can help you make more friends, too．C．Just like your stomach, your mind is also hungry．D．Why not do some reading while you are hungry?E．Also this makes a significant contribution to your vocabulary．F．The interesting part of the book is stored in your mind as a seed．G．Hunger of the mind can be actually solved through wide reading．东城一模第二节：（共5小题；每小题2分，共10分）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。

South Bend 49 up getting over 3 feet of snow.In these 50 of kindness though, I was once again 51 of my belief that that all people are born good. These people didn’t have to stop and help me out. They ran the 52 of having their own cars stuck. Even for myself, it was a(an) 53 reaction to get out and push the lady’s car out too.
