People always shake hands and say“How do you do?”when ________ to each other.

[　　]

It’s always awkward when you meet someone from a different country．You never know whether to shake hands, bow or even whether to kiss on the cheek．But what if you were a dog?

If you are a dog owner, you must be familiar with how your dog says hello to you．Seconds after you arrive home, your dog jumps up on you．You come face to face with a tail-wagging, wildly excited ball of fur that can’t get enough of you．If you’re not happy with that, it will shower you with wet “kisses” perhaps ruining your best shirt．

Like humans, dogs have five senses: smell, touch, sight, hearing and taste．

Unlike humans, dogs use smell rather than sight to identify others around them．A dog’s sense of smell is thousands of times better than that of humans．Your dog can’t just tell what a human being smells like, but it can also tell the difference between different members of its human family by their smell．

They also greet each other this way, not eye to eye, but nose to nose．

To be precise, when they first meet each other, they start with a quick sniff of each other’s noses．Then they will go side to side, working their way towards the back end．

Dogs smell everything they can during a walk．They sniff grass, bushes, trees and signposts．By doing this, dogs know not only what they are looking at, but which other neighborhood dogs have been around lately．

So next time you see your dog sniffing the wrong end of another dog, don’t regard it as a bad habit．They are greeting each other．（295 words）

When people in the U.S. have company or when they're invited to (formal or informal)get-together, they usually make a point of trying to make others feel comfortable and relaxed.On the whole, they tend to be informal. Men shake hands, but usually only when they're introduced. Male friends and business associate who haven't seen each other in a while may shake hands when they say hello. Women usually don't shake hands when being introduced to each other. When a woman and man are introduced, shaking hands is up to the woman. Americans rarely shake hands to say goodbye, except on business occasions. American women are used to being independent. They are used to going to places by themselves, making their own money, and often living alone. Sometimes they will ask men for help, but they usually don't want to be protected. Since the women's movement started, it's not always clear whether women expect men to open doors or help them into their coats. American women may start conversations with men or even ask them to dance.

 There are a lot of Americans who don't smoke or drink, and many who don't want people to do those things in their houses. It's always best to ask for permission before you,bring alcohol to a dinner or before you light up a cigarette, if you are with people you don't ,know very well. Non-smokers have become more militant (好战的) about smoking in public places. Many restaurants, for example, have set up special areas for smokers.

House guests may bring gifts when they come to visit, and they often offer to help in some way. As a guest, you may want to ask your host or hostess if there's anything you can do to help in the kitchen. In many cases, the gesture is more important than actually helping.
