你住在哪里用英语怎么说-人教新教材七年级英语下册Unit 1语法归纳和练习

一、特殊疑问词 why, what 和 where

(一)why

1.含义:why 意为“为什么”,是一个疑问副词,用于引导特殊疑问句来询问原因。

2.用法:

(1)在一般现在时的特殊疑问句中,如果句子的谓语动词是实义动词,主语是第三人称单数,那么 why 后面的助动 词就用 does,否则用 do,句中的谓语动词均用原形。例如:

Why does he go to the hospital?(他为什么去医院?)

Because he is ill.(因为他病了。)

(2) Why 还可以用于向别人提出建议,句型为“Why dont you 动词原形 其他?”或“Why not 动词原形 其他?”,意为“为什么不……呢?”。例如:

Why dont you go out for a walk?(你为什么不出去散散步呢?)

(二)what

1.含义:what 意为“什么”,是一个疑问代词,用于引导特殊疑问句来询问事物、行为或职业等。

2.用法:

(1)对主语提问:

What is in your pocket?(你口袋里有什么?)

(2)对宾语提问:

What did you buy?(你买了什么?)

(3)询问职业:

What is your mother?(你妈妈是干什么的?)

注意,What is 人?此句型是问人的职业,一般译为“是 干什么的?”。

(三)where

1.含义:where 意为“哪里”,是一个疑问副词,用于引导特殊疑问句来询问地点或位置。

2.用法:

(1)询问具体地点:Where do you live?(你住在哪里?)

(2)在句子中作状语,不能对主语提问。例如:I am going to Japan.(我准备去日本。)回答只能用表示地点的词语或句子,如:In Tokyo.(在东京。)

(四)注意事项

特殊疑问句不能用 yes 或 no 来回答,而是需要给出具体的答案。

在实际运用中,特殊疑问句的结构可能会有所变化,但基本遵循“疑问词 助动词/be 动词/情态动词 主语 谓语 其 他成分”的规则。

二、可数名词单复数

(一)可数名词的定义 可数名词是指可以数清数量的名词,它们有单数和复数两种形式。当指一个人或一件事物时,用单数形式;当指两个或多个人或事物时,用复数形式。

(二)可数名词单数变复数的规则

1.一般情况:在词尾加-s。

例如:

book(书)→ books

car(汽车)→ cars

2.以 s、x、ch、sh 结尾的名词:在词尾加-es。

例如:bus(公共汽车)→ buses

watch(手表)→ watches

3.以辅音字母 y 结尾的名词:先将 y 改为 i,再加-es。

例如:city(城市)→ cities

factory(工厂)→ factories

但注意,以元音字母 y 结尾的名词,复数形式只加-s,如:

boy(男孩)→ boys(男孩们)。

4.以 o 结尾的名词:多数加-es,如:

hero(英雄)→ heroes

potato(土豆)→ potatoes

但也有例外,如:

zoo(动物园)→ zoos

radio(收音机)→ radios

此外,某些外来 词也只加-s,如:

photo(照片)→ photos

piano(钢琴)→ pianos。

5.以 f 或 fe 结尾的名词:多数将 f 或 fe 改为 v,再加-es。例如:

leaf(叶子)→ leaves

half(一半)→ halves

但也有例外,如:roof(屋顶)→ roofs

6.不规则变化:有些名词的复数形式是不规则的,需要单独记忆。例如:

man(男人)→ men

woman(女人)→ women

tooth(牙齿)→ teeth

foot(脚)→ feet

child(孩子)→ children

mouse(老鼠)→ mice

(三)可数名词单复数在实际语境中的应用

1.在句子中作主语:

单数形式:

The book is on the table.(书在桌子上。)

复数形式:The books are on the table.(书在桌子上。)

2.在句子中作宾语:

单数形式:I like this book.(我喜欢这本书。)

复数形式:I like these books.(我喜欢这些书。)

3.在句子中作定语:

单数形式:a red book(一本红色的书)

复数形式:red books(红色的书)

(四)特殊名词单复数

1.单复数形式相同的名词:有些名词的单数和复数形式是相同的,如:Chinese(中国人),Japanese(日本人), sheep(绵羊),deer(鹿),fish(鱼,当表示不同种类的鱼时,可以加复数词尾-es 变为 fishes,但通常 fish 作“鱼” 解时仍被视为不可数名词,其复数形式表示“鱼的条数”而非“鱼的种类”)。

2.集体名词:有些集体名词只用作复数形式,如:people(人们),police(警察)。这些名词在句子中作主语时,谓语动词要用复数形式。例如:

The people are happy.(人们很高兴。)

3.不可数名词:与可数名词相对的是不可数名词,它们没有单复数之分,通常表示抽象概念、物质或液体等。不 可数名词的量度通常用“数词 量词 名词”的结构来表示。例如:

a piece of bread(一片面包),a bottle of milk(一瓶牛奶)。
