Some couples choose not to learn the sex of their baby before he or she is born because the moment people hear "boy" or "girl" they begin to make assumptions (设想) about a child. One couple in Sweden decided to take that logic a few steps further, and are refusing to tell anyone whether their child is a boy or a girl. The child–called Pop, to protect his or her identity–is now two years old, and only a few close relatives know the sex. “We want Pop to grow up more freely, Pop’s mother said. Pop wears dresses, and also “male” styled pants and Pop’s hairstyle. changes often. Nordenstrom, who studies hormonal (荷尔蒙) influences on gender, says, “It will affect the child, but it’s hard to say if it will hurt the development. I don’t know what they are trying to achieve. It’s going to make the child different.” She says if Pop is still “genderless(无性的)by the time he or she starts school, Pop will certainly receive a lot of attention from classmates.“We don’t know exactly what determines sexual identity, but it’s not only sexual education,” says Nordenstrom.“Gender-typical behavior, sexual preferences and sexual identity usually go together. There are hormonal and other influences that we don’t know that will determine the gender of the child.” Pop will soon welcome a brother, or a sister. Pop’s parents will not reveal sex of that child, either, except, perhaps, to Pop.

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 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 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. Can an ordinary American tell you his/her value system？

A. Yes, because this is something an American lives by.

B. Yes, because values are something always in their mind.

C. No, because no one cares about his/her value system.

D. No, because he/she has never really thought about it.

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

A. invite foreigners to visit America
