15．Going for Yoga Lessons
"Try and see inside your mind，a wide open blue sky and a vast green plain far away．Breathe in as you circle your hands high above your head，then bend back a little．Breathe out as you circle your arms back down to your sides…"

12．Dear Reader：
    I receive many letters from children and can't answer them all．Now，I'll try to answer the questions that are commonly asked．
    Where did I get the idea for Stuart Little and for Charlotte's Web？Well，many years ago I went to bed one night in a railway sleeping car and dreamed about a tiny boy who acted like a mouse．That's how the story of Stuart Little got started．As for Charlotte's Web，one day when I was on my way to feed the pig，I began feeling sorry for the pig because，like most pigs，he has to die．So I started thinking of ways to save a pig's life．I had been watching a big grey spider（蜘蛛） at her work and was impressed by how clever she was．Gradually I worked the spider into the story．Three years after I started writing it，it was published．
    Sometimes I'm asked how old I was when starting to write，and what made me write．I started early-as soon as I could spell．I don't know why I enjoyed writing，but I think children often find pleasure in trying to set their thoughts down on paper，either in words or in pictures，but I was not good at drawing．
    Are my stories true？No，they are made-up．In real life，a family doesn't have a child who looks like a mouse，and a spider doesn't spin （編織） words in her web．But real life is only one kind of life-there is also the life of the imagination．And I like to think there is some truth in my stories-truth about the way people and animals feel and think and act．
    Yours sincerely，
    E．B．White
50．What is E．B．White？B
A．a traveller       B．Writer           C．farmer           D．painter
51．How long did it take the writer to finish Charlotte's Web？C
A.1 year             B.2 years          C.3 years      D.4 years
52．What can be inferred from the passage？B
A．Stuart Little is about a real mouse seen in a sleeping car．
B．Something in real life can give the writer ideas of writing．
C．Children show interest in writing thoughts down on paper．
D．The writer thinks there is no truth in imaginary stories．
53．What are the readers interested in according to the passage？A
A．when to start writing stories        
B．the spiders in his stories    
C．when to write more stories           
D．the writer's family．
