增长趋势考点一:询问某物数量的问答

—How many classes do you have today, Mike?

—I have six classes today.

解析:

(一)核心单词解析

1.How many 意思:多少(用于询问可数名词的数量)

用法:后面必须跟可数名词的复数形式(如 classes,不能说 “How many class”)。

例:How many pens do you have?(你有多少支钢笔?)

2.class意思:课;班级(此处指 “课”)

复数形式:classes(以 “s” 结尾的名词变复数,加 “es”)

例:two classes(两节课);our class(我们班)

3.have 意思:有(此处表示 “拥有” 课程)

用法:主语是第一人称(I/we)、第二人称(you)或复数名词时,用 “have”;主语是第三人称单数(he/she/it)时,用 “has”。例:I have a book.(我有一本书。);He has three pencils.(他有三支铅笔。)

(二)句型结构解析

1. 问句结构:How many + 复数名词 + do you have + 时间状语?

(用于询问对方在某个时间有多少数量的某物)

How many classes(多少节课)→ 疑问词 + 复数名词,表询问数量;

do you have(你有)→ 助动词 “do”+ 主语 “you”+ 实义动词 “have”,构成疑问句;

today(今天)→ 时间状语,说明 “有课” 的时间。

2. 答句结构:主语 + have + 数字 + 复数名词 + 时间状语page number 1

(直接回答 “拥有某物的数量”,与问句结构对应)

(1)I(我)→ 主语,对应问句的 “you”;

(2)have(有)→ 实义动词,与问句的 “have” 一致;

(3)six classes(六节课)→ 数字 + 复数名词,回答 “数量”;

(4)today(今天)→ 时间状语,与问句的 “today” 呼应。

(三)用法提示

1.当询问 “第三人称”(如 Mike、Lucy、he、she)有多少课时,问句要把 “do you have” 换成 “does he/she have”,答句把 “I have” 换成 “He/She has”。

例:—How many classes does Lucy have today?(露西今天有多少节课?)

—She has five classes today.(她今天有五节课。)

2.“How many” 只能问 “可数名词”(能数出数量的词,如 classes, pens, books),问 “不可数名词”(如 water, milk)要用 “How much”。

错例:How many milk do you have?(×)

正例:How much milk do you have?(你有多少牛奶?)

(四)情景应用

这个对话常用于学生之间、师生之间询问 “当天的课程数量”,比如:

早上到校时,A 问:“How many classes do you have today, Tom?”(汤姆,你今天有多少节课?)B 回答:“I have six classes today.(我今天有六节课。)”
