 71  Because, from what I could see, it seemed that grown-ups often forgot. I never wanted to forget --- I wanted to be able to remind other adults and myself when the time came. I began consciously(有意识地) thinking this at quite an early age.

As soon as I was fully aware (意识到) of myself, I regarded me as a little person and liked adults who thought of and treated me the same way. I didn’t have a doll and I didn’t want one. I wanted animal toys, even a single animal. Why wouldn’t my parents give me the one thing I wanted?  72  

Instead, my dad somehow managed to buy me a full set of encyclopedia(百科全书) and books with maps and color pictures long before I could read. Well, guess what? I learned to read without realizing it! Later, I found out when I started school and it all came so easy especially geography.  73  Because of all the books my father bought me, I knew a lot of words that other children didn’t know at my age.

I love words. They opened up new worlds for me.  74  Parents, please make sure your kids have a computer. Let them explore — as safely as possible— let them do their own things and discover the world.

Now, most kids lead a happy life. They can get what they want from their parents. But children should learn to be independent.  75  Be independent to do your own things.

A.Because of them, I read and thought, and today, I write.

B.When I was a child, I promised myself to try to remember as much as I could.

C.I listened and heard everything, even if I didn’t understand everything.

D.I nearly knew every place on the map like the teacher.E. But more than anything, it made me feel uncomfortable and I knew it wasn’t nice.

F. Later, I knew we didn’t have much money, but how expensive could a toy be?

G. Be independent to learn some useful knowledge.
