【例句感悟】
*—How old are you?你多大了?
—I'm twelve. 我12岁了。(教材·PS12)
*—How old is Daming?大明多大了?
—He is eleven. 他11岁。
【探究归纳】
询问年龄句式: How old +be+主语?其答语:主语+be+数字(+year(s) old).

A. am B. is C. are D. be
解题点拨:题意:——你表弟多大了?——他11岁。is是单数,are是复数,am通常与I连用。
【学以致用】

*—How many boys are there?有多少个男孩在那里?

【探究归纳】
当问“有多少……?”时,有以下两种形式:
(1) How many +可数名词复数+are+there?
(2) How much +不可数名词+is+there?

在你们班有多少个学生? (汉译英)
How many students are there in your class?
解题点拨:本题考查数量的问法,是特殊疑问句。student是可数名词,故用How many +可数名词复数+are there?提问;提问范围“在你们班”为in your class。
