阅读快车系列答案Smiling
People smile at times. However, the meaning of a smile in different cultures may be different. Depending on different cultures, smiling can express joy and amusement, but it can also indicate embarrassment（苦恼）. The following examples show this point of view:
In an attempt to be open and friendly, people in the United States smile a lot. Every one smiles at each other, this nonverbal communication shows being friendly in the United States. However，in China, smiling is not only an expression of happiness, but also a way to avoid being embarrassed. Chinese people like smiling when they are embarrassed in order to avoid embarrassment. Smiling is a kind of good will but not sneer（嘲笑）. For example: When a child falls off from a bike, the adults in China may smile, which is a kind of gentle encouragement and may not be a kind of impolite laugh.
When a person from the United States might blush（脸红）with embarrassment or become offensive, a Chinese might blush with smile. To avoid serious misunderstanding, people who engage in intercultural communication should be able to understand the meaning of smiling appropriately. Related to the smile is the laugh. Also, different cultures have different meanings about laugh. For example, Americans can enjoy a very heartfelt belly (腹部) laugh that comes from the deepest emotions. However, most Chinese seldom laugh that way because they are thought to be silly except among close friends.

Making greener choices and encouraging healthy lifestyles can promote your health and benefit the environment．Here are some guidelines to follow:
Choose foods thoughtfully
Americans have never had such a variety or abundance of food to choose from．Besides so many choice
s, we now hear about our "food print", the amount of land needed to supply o
ne person's nutritional needs for a year．Do we buy cherry tomatoes from Mexico or tomatoes grown locally in a hothouse? Do．we get the Granny Smiths from the fanners' market or the supermarket? Is organic produce healthier for us and the planet?
These are very complex issues that require analysis of many criteria, including the energy used in producing and transporting the food, as well as the type of soil and methods of raising the food．
Despite the complexities, there are some general guidelines you can follow．For instance, eat less meat or eat low on the food chain．Your doctor may have recommended you to restrict your consume red meat because of its too much fat content．Beyond that, there are environmental reasons, too.

Drinking plenty of fluids is significant during hot weather or when exercising．But is bottled water the way to go? You may not think so when seeing the true costs．Based on a survey, manufacturing the 30 - plus billion plastic water bottles can produce more than 2．5 million tons of carbon dioxide and use here times the amount of water in the bottle．Adding in transportation, the energy used comes to over 50 million barrels of oil equiv
alent （等价物）．Consequently, skip the bottled water and drink tap water, both at home and at restaurants．Additionally, bottled water is not necessarily cleaner than tap.

America is a mobile society. Friendships between Americans can be close and real, yet disappear soon if situations change. Neither side feels hurt by this. Both may exchange Christmas greetings for a year or two, perhaps a few letters for a while—then no more. If the same two people meet again by chance, even years later, they pick up the friendship. This can be quite difficult for us Chinese to understand, because friendships between us develop more slowly but then may become lifelong feelings, extending(延伸) sometimes deeply into both families.
Americans are ready to receive us foreigners at their homes, share their holidays, and their home life. They will enjoy welcoming us and be pleased if we accept their hospitality(好客) easily.
Another difficult point for us Chinese to understand Americans is that although they include us warmly in their personal everyday lives, they don’t show their politeness to us if it requires a great deal of time. This is usually the opposite of the practice in our country where we may be generous with our time. Sometimes, we, as hosts, will appear at airports even in the middle of the night to meet a friend. We may take days off to act as guides to our foreign friends. The Americans, however, express their welcome usually at homes, but truly can not manage the time to do a great deal with a visitor outside their daily routine. They will probably expect us to get ourselves from the airport to our own hotel by bus. And they expect that we will phone them from there. Once we arrive at their homes, the welcome will be full, warm and real. We will find ourselves treated hospitably.
For the Americans, it is often considered more friendly to invite a friend to their homes than to go to restaurants, except for purely business matters. So accept their hospitality at home!
