　　1．How do you do？您好。
　　这是用于第一次见面时的较正式用语。一般用同样的话来回答。请参见 Lessons 5～6课文详注。
　　2．Come and meet our employees…来见见我们的雇员……
　　这里的and表示目的。请参见 Lessons 13～14中语法部分的解释。

　　这是介绍人们彼此认识时的常用句型。请参见 Lessons 5～6课文详注。
　　4．名词的复数形式（2）
　　如果名词单数词尾为-f或-fe（读作／f／），则其复数一律变为-ves （读作／vz／），即将-f或-fe变成-v，再加-es而成，如 housewife ---- housewives。
　　英语中有一些名词的复数形式是不规则的，如man与woman其复数形式分别为men与women。此外还可用man，woman等来区别阳性与阴性：以-man结尾的一些复合名词指男性，如milkman ---- milkmen，policeman ---- policemen；一些以-woman结尾的名词指女性，如postwoman ---- postwomen，policewoman ---- policewomen。
　　5．数字200，1,000，1,001的英文写法

　　1,001 ---- a thousand and one

　　注意这种句型与 What is…？或 What are…？这类句型的区别：What…？句型主要用来询问人的类别或职业。请参见 Lessons 5～6与 Lessons 7～8语法部分的解释。
