【考点一】 询问他人职业的句型
【考点二】询问某人能为他人做什么的句型
【考点三】情态动词can的用法
【考点四】职业名词
考点一:询问他人职业的句型
【课文原句】
—What’s your mother’s job? 你妈妈做什么工作的?
—She is a doctor. 她是一名医生。
【句型结构】
问句:What's + his/her/ 名词所有格 + job?
答语:He's/She's a/an + 职业名称.
例句:—What's your uncle's job?你叔叔做什么工作?
—He's a teacher.他是位老师。
—What's her job? 她做什么工作?
—She's a nurse. 她是位护士。
【拓展】询问他人职业的其他句型
【句型结构】What does+某人+do?
例句:—What does your father do?你父亲做什么职业?
—He is a doctor.他是一名医生。
【重点解析】
· a 后接发音以辅音音素开头的职业名称;
· an 后接发音以元音音素开头的职业名称
【拓展】名词所有格
名词所有格表示所属关系,意为 “…… 的”,后要接名词(短语)。
’s所有格:一般与有生命的事物(如人或动物等)连用
①一般情况下,单数名词词尾加 “'s”
例如:Sam's football 萨姆的足球
②以s结尾的复数名词词尾加 “'”
例如:Teachers' Day 教师节
③不以s结尾的复数名词词尾加 “'s”
例如:Children's Day 儿童节
of 所有格:一般与无生命的事物连用与 of 构成短语
例如:the name of the school 这所学校的名字
【易错点】职业前冠词的搭配
· 遗漏冠词,直接说 “She is doctor”(职业名称前通常需加冠词 a/an);
· 混淆 “a” 和 “an”
①若职业以元音音素开头,用an;如an office worker
②若职业以辅音音素开头,用a;如a farmer
【大显身手】
1、 选择题。
( ) 1.—What’s ______ job?
—______ is a worker.
A.his; She B.her; Her C.his; He
( ) 2.—What’s your mother’s job?
—She’s ______ English teacher.
A.a B.an C.the
( ) 3.—______ your mother’s job?
—She’s a nurse.
A.What B.What’s C.Where
二、 句型转换。
4.My uncle is a football player. (对划线部分提问)
job?
5.What does your brother do? (同义句转换)
What job?
考点二:询问某人能为他人做什么的句型:
【课文原句】
—What can we do for them?我们能为他们做些什么呢?
—We can do some chores.我们可以做些家务。
【句型结构】
问句:What can + 主语 + do for + 某人?
答语:主语 + can + 动词原形 (+ 其他).
例句:—What can the boy do for his grandmother?这个男孩能为他奶奶做些什么?
—He can water the flowers. 他能浇花。
【重点解析】
· can 为情态动词,意为 “能;可以”,没有人称和数的变化,后接动词原形
· 问句中 do 作实义动词,意为 “做;干”
· for 作介词,后接人称代词时,要用其宾格形式
【拓展】情态动词can的语法特点
· 没有人称和数的变化,其后接动词原形。
· 否定形式为 “can't”(cannot 的缩写)。
· 一般疑问句将 “can” 提到主语之前,答语用 “can” 或 “can't”。
例:—Can he dance?(他会跳舞吗?)
—Yes, he can. / No, he can't.(是的,他会。/ 不,他不会。)
【易错点】can 是情态动词,其后必须接动词原形,无论主语是第几人称,动词都用原形do。
What can he do for his mum?
What can he does for his mum?
【大显身手】

考点三:情态动词can的用法:
can 为情态动词,在句子中,与动词原形一起构成谓语,没有人称和数的变化。
一、用法:
1.表示 “能,会”,指脑力或体力方面的 “能力”。
例:I can swim. 我会游泳。
2.表示 “可以”,指许可或请求做某事。

4.I can to clean my room.
二、句型转换。
5.Mary can swim very well. (对画线部分提问)
6.Can you play basketball at school? (改为陈述句)
考点四:职业名词:
英语中,在一些动词的词尾加上后缀 -er、-r、-or 或双写末尾字母加 -er 可以构成表示职业的名词。
work(工作)→ worker(工人) sing(唱歌)→ singer(歌手)
write(写作)→ writer(作家) act(表演)→ actor(演员)
swim(游泳)→ swimmer(游泳者)
注意:
cook 是个例外,cook 既可作动词,意为 “烧,煮”,也可以作名词,意为 “厨师”;动词 cook 后面也可以加 -er,即 cooker,意为 “炊具,炉灶”,而不是 “厨师”。
