Small talk is a good way to kill time and make friends. If you travel to other countries, do you know what to say to        small talk with local people?

In Britain the best topic is the weather. British        changes quite often. It’s a safe topic. You can start small talk simply by saying “It’s a lovely day today, isn’t it?”      the weather, it’s good to talk about gardens with English people. For example, you could say, “Those roses look really beautiful,       ?” English people love their pets. So it’s also nice to begin with “What a lovely        ! What’s its name?”

In America, people like to talk about sports,        Amecican football and basketball. They also talk about clothes by saying “It’s a nice shirt! Where did you get it?” The weather is a        topic there, too.

Of course, you should avoid a lot of topics during small talk in western countries. Don’t ask people “How old are you?”. Age is usually secret ,        for women.        ask “How much money do you make?” It makes people uncomfortable. Don’t ask strangers whether they have a girlfriend         boyfriend. Politics(政治) and religion(宗教) is not a good topic for two people who have just met, either.
