Lesson 17:How do you do?(你好!)

一:名词复数的变化规则?

实际上名词复数的变化规则多种多样,此处暂且写一些常用的规则:

  1. 以“ f ”或者“ fe ”结尾的,将“ f/fe ”变为“ v ”,再接“ -es ”,读为“/vz/”;
例子

housewife ---> housewives
knife ---> knives

  1. 辅音字母 + y 进行结尾的,变“ y ”为“ i ”,再接“-es”,读为“/z/”;
例子

country ---> countries
family ---> families
city ---> cities

  1. 元音字母 + y 进行结尾的,直接单词后尾接“ s ”。
例子

day ---> days
boy ---> boys
monkey ---> monkeys

总结就是,名词复数的变化规则既有规则的(例“body”变为“boys”等),也有不规则的(“woman”变为“women”等),当如果拿捏不足的话一定要去查词典。


二:名词复数的发音规则?

  1. 名词词尾的发音为清辅音的(除/s/、/ʃ/、/tʃ/),例如/t/、/k/、/f/等,在接续“ -s ”的时候会发/s/的音;
例子

books(/bʊks/)
cooks(/kuʊks/)

  1. 名词词尾的发音为元音或浊辅音(除/z/、/ʒ/、/dʒ/),例如/b/、/d/、/g/等,在接续“ -s ”的时候会发/z/的音;
例子

ties(/taiz/)
birds(/bə:dz/)
bags(/bægz/)

  1. 名词词尾的发音为/s/、/ʃ/、/tʃ/、/z/、/ʒ/、/dʒ/,在接续“ -s ”的时候会发/iz/的音。(重点)
例子

dresses(/'dresiz/)
watches(/wɒtʃiz/)
blouses(/'blauziz/)


三:Who 引导的特殊疑问句?

特殊疑问句 = 特殊疑问词(如:what、where、how、whose、who等) + 一般疑问句(去掉答案)

例子

That is Marisa.
Is that Marisa?(一般疑问句)

一般疑问句 --> 特殊疑问句

 ┌-----------------------┐
 ↓                       |
    Is that (Marisa --> who)? 

Who is that? / Who's that?

四:如何表达“过来见见某人”?

Come and meet ...(过来见见某人)

例子

Come and meet our employees, Mr.bean.
Come and meet our friend, Mellie.
