首先，how many句型一般是来问数量的多少的。

其次，how many句型一般与there be连用。回答一：直接回答数量，如2/two。回答二：完整回答，加上there be，如there are two。how many是问多少，回答也应该回答数量。然后就是根据问句中的具体形式，进行回答。需要注意的就是因为how many是可数名词，所以回答时要用数字等可数词来回答。-How many girls are there in your class -only onehow many是对可数名词的确复数进行提问，后接复数，用数字回答。如：How many do you smoke a day？你一天抽多少根烟？How many例句:1.How many students are there in your class 你们班有多少个学生 2.How many dynasties are there in China's history 中国历史上有多少个朝代 3.How many people have accessed your homepage by now 到目前为止,有多少人访问了你的主页 4.How many feeds a day does this dog get 这只狗每天吃几顿 5.How many military bases are they maintaining on foreign soil 他们在外国保持多少个军事基地 6.How many ribs does a man have 一个人有几条肋骨 7.How many inches of rain fell last year 去年的雨量是多少英寸 8.How many ventricles of heart does a man have 每个人有几个心室
