阅读理解。

     Most Americans would have a difficult time telling you, specifically, what are the values which Americans

live by. They have never given the matter any thought.

     Over the years I have introduced thousands of international visitors to life in the United States. This has

caused me to try to look at Americans through the eyes of foreign visitors. I am confident that the values

listed in this booklet describe most( but not all) Americans, and that understanding these values can help you,

the international visitor, understand Americans.

      It is my belief that if foreign visitors really understand how deeply these 13 values are ingrained in

Americans, they will then be able to understand 95% of American actions-actions which might otherwise

appear "strange","confusing", or "unbelievable" when evaluated from the perspective ( aspect) of the foreigner's

own society and its values.

     The different behaviors of a people or a culture make sense only when seen through the basic beliefs,

assumptions and values of that particular group. When you encounter ( meet) an action, or hear a statement in

the United States which surprises you, try to see it as an expression of one or more of the values listed in this

booklet.

1. An ordinary American can't tell you his/her value system because _____.

A. this is something an American lives by

B. everyone will have his/her own value system

C. he/she has never thought about it

D. values are something often in their thought

2. The author lists 13 values in his booklet to _____.

A. invite foreigners to visit America

A. rooted in the minds

    probably because _____.
