Part 1 · 职业描述句型
定义:描述职业及日常工作
?
介绍某人的身份、职业及他/她经常做的事情时,使用:
主语 + be动词(am/is/are) + a/an + 职业名词
核心功能:表达"某人是做什么的"及经常性动作。
例句:
He is a doctor. He often helps people.
(他是个医生。他经常帮助人们。)
解析:He是三单→be动词is help→helps(三单变化)
注意:
主语是he/she/it/单数人名时,动词要加-s/-es(三单变化)。
描述日常工作用一般现在时,可加频率副词often/usually。
1.7.2013
职业描述句型:主语+be+a/an+职业名词。主语是三单时动词加-s。例句:He is a doctor. He often helps people.
‹#›
Part 1 · 职业描述句型
职业名词构词法(后缀 -er / -or / -ist)
后缀 -er(最常见,"做……的人")
teach + er = teacher(教师)
clean + er = cleaner(清洁工)
work + er = worker(工人)
后缀 -or(动词 + or)
act + or = actor(男演员)
visit + or = visitor(游客)
后缀 -ist(从事专业/艺术的人)
art + ist = artist(艺术家)
science + ist = scientist(科学家)
记忆口诀:动词加er变职业,teach→teacher;
动词加or也常见,act→actor;名词加ist表专业,art→artist。
本单元相关:firefighter(fire+fighter)、cleaner(clean+er)、driver(drive+r)。
1.7.2013
职业名词构词法三种后缀:-er(最常见,teach→teacher)、-or(act→actor)、-ist(art→artist)。本单元词汇:firefighter、cleaner、driver。

Part 1 · 职业描述句型
如何询问职业
1
询问工作内容(最常用)
结构:What do/does + 主语 + do?
— What does he do? (他是做什么的?)
— He is a firefighter. (他是消防员。)
注意:do/does取决于主语人称和数。
2
询问职位名称
结构:What is + 主语's job?
— What is your mother's job?
(你妈妈的工作是什么?)
— She is a cook. (她是厨师。)
助动词选择规则:
主语是 I/you/we/they/复数 → 用 do:What do you do? What do they do?
主语是 he/she/it/单数人名 → 用 does:What does he do? What does your mother do?
易错点:What does he do? 中第二个do是实义动词"做",不是助动词!
回答时用:He is a + 职业名词. 不是 He does a teacher.
1.7.2013
两种询问职业的句型:①What do/does+主语+do? ②What is+主语's job? 助动词do/does取决于主语人称。
