英语 Small Talk 的小技巧
英语Small Talk 的小技巧何为small talk?Small talk: Conversation without real meaning; conversation without any particular purpose; conversation about general subjects; conversation one starts with unfamiliar people in order to be more involved; conversation used to make friends with new people; conversation used to make the atmosphere better.所谓small talk，就是“闲聊、寒暄”的意思，指没有具体意义的对话；没有特殊目的的对话；关于大众话题的对话；为了进一步融入而展开的与陌生人的对话；为了结交新朋友而展开的对话；为了使气氛更融洽而展开的对话。
Good topics（适合的话题）1. How was your flight or train ride? Perhaps the first question you would ask them, out of politeness.旅途如何？这可能是你首先该问的问题，比较礼貌。
2. How is your hotel? If they have already checked into a hotel, you can ask if their accommodations are acceptable to them. Just another polite question.你的旅馆如何？如果他们已经入住的话，你可以问问他们觉得住宿是否可心，这又是一个比较礼貌的问题哦。
3. Do you play any sports? / Do you play golf? This is a good question to ask Western businessmen especially. Most of them do play golf - it has become very, very common in recent years. Others might play tennis, squash or basketball. Most Western women do yoga or at least go to the gym.你做什么运动吗？你打高尔夫吗？这个是可以问西方商务人士的很典型的话题。
SmallTalk（闲聊技巧）
Making Small TalkMaking Small TalkThe ability to make 'small talk' is highly valued. In fact, many English students are more interested in making effective small talk than knowing correct grammar structures - and rightly so! Small talk gets friendships started and 'breaks the ice' before important business meetings and other events.What is small talk?Small talk is pleasant conversation about common interests.How to Improve Small Talk SkillsNow that we understand the problem, the next step is to improve the situation. Here are some tips to improve small talk skills. Of course, making effective small talk means lots of practice, but keeping these tips in mind should improve overall conversational skills.Do some researchSpend time on the Internet, reading magazines, or watching TV specials about the type of people you are going to meet. For example: If you are taking a class with students from other countries, take time after the first few days of class to do some research. They will appreciate your interest and your conversations will be much more interesting.Stay away from religion/strong political beliefsWhile you may believe in something very strongly, beginning conversations and making small talk about your own personal convictions may abruptly end the conversation. Keep it light, don't try to convince the other person that you have the 'correct' information about a higher being, political system or other belief system.Use the Internet to gain specific vocabularyThis is related to doing research about other people. If you have a business meeting, or are meeting people who share a common interest (a basketball team, a tour group interested in art, etc.), take advantage of the Internet to learn specific vocabulary. Almost all businesses and interest groups have glossaries on the Internet explaining the most important jargon related to their business or activity.Formal Greetings: ArrivingGood morning / afternoon / evening.Hello (nam e), how are you?Good day Sir / Madam (very formal)Informal Greetings: ArrivingHi / HelloHow are you?What's up? (very informal)How are you doing? (very informal)It's important to note that the question "How are you?" or "What's up?" doesn't necessary need a response. If you do respond, these phrases are generally expected:Very well, thank you. And you? (formal)Fine / Great (informal)Formal Greetings: DepartingGood morning / afternoon / evening.It was a pleasure seeing you.Goodbye.Note: After 8 p.m. - Good night.Informal Greetings: DepartingGoodbye / Bye.See you (later).Later (very informalAsk yourself about your cultureTake time to make a list of common interests that are discussed when making small talk in your own culture. You can do this in your own language, but check to make sure that you have the English vocabulary to make small talk about those subjects.Find common interestsOnce you have a subject that interests both of you, keep to it! You can do this in a number of ways: talking about travel, talking about the school or friend you have in common, talking about the differences between your culture and the new culture (just be careful to make comparisons and not judgments, i.e., The food in our country is better than the food here in England").ListenThis is very important. Don't get so worried about being able to communicate that you don't listen. Listening carefully will help you understand and encourage those speaking to you. You might be nervous, but letting others state their opinions will improve the quality of thediscussion - and give you time to think of an answer!Here is a list of common small talk subjects. If you have difficulties speaking about any of these topics, try to improve your vocabulary by using the resources available to you (Internet, magazines, teachers at school, etc.)∙Sports - current matches or games, favorite teams, etc.∙Hobbies∙Weather - boring, but can get the ball rolling!∙Family - general questions, not questions about private matters∙Media - films, books, magazines, etc.∙Holidays - where, when, etc. but NOT how much!∙Home town - where do you come from, how is it different/similar to this town∙Job - once again, general questions not too specific∙Latest fashion and trends∙Celebrities - any gossip you may have!Hot Questions to start a small talkFive Basic FactsThese five questions will help you get to know people. They are simple questions with simple answers and provide information so you can ask more questions.What is your nam e?Where do you live?What do you do?Are you married?Where are you from?More questions for ...These questions help to continue the conversation after your first question."What is your name?"It's a pleasure to meet you. Where are you from?That's an interesting name. Is it Chinese / French / Indian, etc.?"Where do you live?"How long have you lived there?Do you like that neighborhood?Do you live in an apartment or house?"What do you do?"Which company do you work for?How long have you had that job?Do you like your job?What's the best / worst thing about your job?What do you like best / least about your job?"Where are you from?"Where is ....?How long did you live there?What is XYZ like?Do you like living here?Hobbies / Free TimeThese questions will help you continue conversations and find out more about people's likes and dislikes.What do you like doing in your free time?Can you play tennis / golf / soccer / etc.?What kind of films / food / vacations do you enjoy?What do you do on weekends / Saturdays?More questions for ...These questions will help you ask for more detail."What do you like doing in your free time?"How often do you (listen to music, eat out in restaurants, etc.)?Where do you (listen to music, eat out in restaurants, etc.) in this town?Why do you like (listening to music, eating out in restaurants, etc.) so much?"Can you play tennis / golf / soccer / etc.?"Do you enjoy playing tennis /golf /soccer /etc.?How long have you played tennis /golf /soccer /etc.?Who do you play tennis /golf /soccer /etc. with?"What kind of films / food / vacations do you enjoy?"What's the best place to see /eat / go on vacations?What's the best type of film /food / vacation, etc. in your opinion?How often do you watch films / eat out / go on vacation?"What do you do on weekends / Saturdays?"Where do you go to ...?Could you recommend a good place to (go shopping / take my children swimming / etc.)? How long have you done that?Here is a list of topics that probably aren't very good for small talk. Of course, if you are meeting a close friend these topics may be excellent. Just remember that 'small talk' is generally discussion with people you don't know very well.∙Salary - how much do you make? - That's none of your business!∙Politics - wait to you get to know the person better∙Intimate relationships - only for you and your partner - or maybe your best friend ∙Religion - tolerance is the key!∙Death - we need to face it, but not the first time we meet someone new∙Financial - related to salary above, most people prefer to keep financial information to themselves∙Sales - Don't try to sell something to someone you have just met.This video with Ellen Quish, an ESL specialist from the Adult Learning Center at LaGuardia Community College in New York City, will help you practice ways of introducing yourself. The video highlights the most common English introduction vocabulary and phrases.。

构造函数
Smalltalk 没有构造函数。如果你想执行实例初始化，你可以重定义 “new”类方法来初 始化实例。
Java
Smalltalk
Reservation()
Reservation class methods:
{
new
startTime =
^super new initialize
new GregorianCalendar().getTime();
特定词
Smalltalk 中，nil 引用一个真实的对象，它是 UndefinedObject 类的实例。true 是 True 类的实例，flase 是 Flase 类的实例
Java
Smalltalk
this
self
null
nil
true
true
false
false
super base (C#)
super
Java
Smalltalk
if (tries > 5) return "Too many tries"; else return "Trying again";
tries > 5 ifTrue: [^'Too many tries'] ifFalse: [^'Trying again']
注意^表示从方法返回，不只是适用于块。
alternatively:
5 timesRepeat: [self tryAgain]
注意 timesRepeat: 是整数类型能理解的消息。它简化了块执行的次数
学习资料
本文档包含了 Smallalk 块速介绍。除了语法，还有很多东西需要学习。其它的东西属于 类库部分。其它学习资料可以到 Dolphin Smalltalk 学习，当然更推荐到 CincomSmalltalk 学习。
myAccount.equals (anotherAccount);
运算优先级：
myAccount = anotherAccount
一元运算符（首先运算） 二元运算符（其次运算） 关键字（最后运算）
在同等优先级下，运算是从左到右
Java
Smalltalk
3 + 5 * 6 //答案是 33
3 + 5 * 6 “答案是：48”
语法结束
到此为止，我们已经介绍了 Smalltalk 所有的语法。其余的事情属于类库部分。你是否 注意到我们是否忘记了某些事情？if-then-else 或者 while 循环？Smalltalk 只使用块 和普通的消息发送。
控制结构
Smalltalk 没有在语言中内置控制结构。Smalltalk 使用向 true 或者 flase 对象发生消 息作为替代。
myAccount deposit: 20.
myAccount.transfer(20,anotherAccount); myAccount transfer: 20 to:anotherAccount
常量
Smalltalk 中整数类型，字符类型，字符串类型，布尔类型，浮点数类型和双精度浮点数类 型都是头等类对象。整数类型是无限精度的，会按需自动增长，而不会溢出（译者注：跟内 存大小有关）。实际上，Smalltalk 中没有 char 类型，byte 类型，short 类型，int 类型或 者 long 类型的相对应的类型。它们都是整数类型。
endTime =
Reservation instance method:
new GregorianCalendar().getTime(); initialize
}
startTime := Timestamp now.
endTime := Timestamp now
方法
Java
class Room { void book (DateTime start, DateTime end) { reservations.add ( new Reservation(start, end)); }
Smalltalk "comment"
实例创建
Smalltalk 中，类是真实的对象。创建实例，只需向 class 发送 new。针对类的方法称为 类方法（类似于 Java 的 static methods）。
Java new Reservation();
Smalltalk Reservation new
注意 Smalltalk 版本，这个表达式实际上是两个消息：
消息 1 接受者：3 消息： + 参数：5
结果： 8
消息 2 接受者： 8 消息： * 参数： 6
结果：48
语句
Smalltalk 使用句号分割语句。最后一条语句不需句号。
Java
Smalltalk
myAccount.deposit(20);
以小写字母开始的 0
字符和数字
二元运算符
连接符
1
关键字
使 用多 个冒 号 终结 1 或者多个
文字和数字字符
例子 squared
+ do: between: and:
传输一个或多个参数时，需要使用关键字消息。每一个参数前面需要添加关键字。Smalltalk
不使用{}和；分割参数
例子
Java
Smalltalk
执行“块”无需参数，可以向它发送一个 value 消息
Smalltalk
| block | block := [3 + 4]. block value "answer is 7"
块可以有参数，每一个块参数的声明必须以冒号（：）开头，以竖线（|）表示参数列表 的结束和块代码的开始。
Smalltalk
| block | block := [:x :y | x * 2 + y]. block value: 5 value: 3 "answer is 13"

Simberson 公司的 David Buck 撰写的此文档是为 C/C++/C#/Java 程序员介绍 Smalltalk 的， 而且已经得到他善意的许可而得以发布。如果你对正式的培训有兴趣请联系 Simberson，咨 询 Smalltalk 培训。
myAccount.getBalance();
myAccount getBalance
myAccount.setBalance (10);
myAccount setBalance: 10
myAccount.transfer(20,anotherAccount) myAccount transfer: 20 to:anotherAccount
我听说很多 Java 和 C#程序员说他们看不懂 Smalltalk 代码。Smalltalk 因为只有很少的语 法，所以实际上它非常的简单。Smalltalk 的强大之处是它的环境和类库。
本文意图通过代码对比，使 Java 和 C#程序员迅速理解 Smalltalk。 © Copyright David Buck 2005
方法返回
Java return value;
级联
Smalltalk ^value
Java <无对应物>
注释
Smalltalk
myAccount deposit: 20; transfer: 20 to: anotherAccount
Java
/* comment */ // another comment
循环
Smalltalk 使用块做循环。由于块是对象，所有我们可以先他们发生消息
Java
Smalltalk
int tries = 0; while (tries <= 5) { tryAgain(); tries++; }
| tries | tries := 0. [tries <= 5] whileTrue: [ self tryAgain. tries := tries + 1]
}
Smalltalk
bookFrom: startTime to: endTime reservations add: (Reservation from: startTime to: endTime)
块
Smalltalk 称对象为块，它是包含可执行代码的对象。Java 中最相似的东西是匿名内部类， C# 2.0 中，跟匿名托管相类似。
临时变量
Smalltalk 不需要变量的类型声明。临时变量通过两个竖线来定义
Java
Smalltalk
int a;
char b;
|abc|
float c;
赋值
Smalltalk 使用 := 赋值
Java
a = 5;
Smalltalk
a := 5
消息
Smalltalk 有三种消息
