     Even before my father left us,my mother had to go back to work to support our family.Once

I came out of the kitchen,complaining,"Mom,I can't peel potatoes.I have only one

hand."

     Mom never looked up from sewing."You get yourself into that kitchen and peel those

potatoes," she told me."And don't ever use that as an excuse for anything again!"

In the second grade,our teacher lined up my class on the playground and had each of us race

across the monkey bars,swinging from one high steel rod to the next.When it was my turn,

     I shook my head.Some kids behind me laughed,and I went home crying.

That night I told Mom about it.She hugged me,and I saw her "we'll see about that"

look.The next afternoon,she took me back to school.At the deserted playground,Mom

looked carefully at the bars.

    "Now,pull up with your right arm," she advised.She stood by as I struggled to lift myself

with my right hand until I could hook the bar with my other elbow.Day after day we

practiced,and she praised me for every rung I reached.I'll never forget the next time,

crossing the rungs,I looked down at the kids who were standing with their mouths open.

One night,after a dance at my new junior high,I lay in bed sobbing.I could hear Mom come

into my room."Mom," I said,weeping,"none of the boys would dance with me."

     For a long time,I didn't hear anything.Then she said,"Oh,honey,someday you'll be

beating those boys off with a bat." Her voice was faint and cracking.I peeked out from my

covers to see tears running down her cheeks.Then I knew how much she suffered on my

behalf.She had never let me see her tears.

     There are several ways you can find out about the countries and places you wish to visit. You can talk

to friends who have travelled to the places. Or you can go and see a color film. Or you can read travel books.

     It would seem that there are three kinds of travel books. The first are those that give a personal, subjective

(主观的) account of travels which the author has actually made himself. If they are informative and have a

good index (索引), then they can be useful to you when you are planning your travels. The second kind are

those books whose purpose is to give a purely objective (客观的) description of things to be done and seen.

If a well-read, cultured person has written such a book, then it is even more useful. It can be sorted as a

selected guide book. The third kind are those books which are called"a guide" to some place or other. If they

are good, they will, in addition to their factual information, give an analysis or an explanation. Like the first

kind they can be inspiring and interesting. But their basic purpose is to help the reader who wishes to plan in

the most practical way.

     Whatever kind of travel book you choose you must make sure that it does not describe everything as

"wonderful", "excellent" or"magical". You must also note its date of publication because travel is a very

practical affair and many things change quickly in the twenty-first century. Finally, you should make sure

that the contents are well presented and easy to find.
