How many teacher is there?还是How many teachers are there?如果只有一个teacher呢?
问题描述：
How many teacher is there?还是How many teachers are there?
如果只有一个teacher呢?
答
首先，提问者不知道有几个老师。
再者，how many 后加可数名词复数，相应的谓语动词也就要用复数形式。
所以 How many teachers are there? correct!
答
后者
你知道只有一个，干吗还要问
答
How many teachers are there?
many 后面要跟可数名词复数形式
答
在不知道的情况下，就得用 How many teachers are there?
答
How many teachers are there?
是对的。How many 后跟名词复数teachers 所以要作are 了。
我是英语教师，不明可再问。
答
第二个对。如果是teacher就用第一个。
答
is表单数，只有一个还问什麼How many 啊？
答
必须用第二个,how many后必须接复数,而且是可数名词,不可数用how much,1楼说的对,前提你是不知道有多少或者几个老师的,最重要的是how many后要跟复数!
答
用 how much teachers are there.
答
are
回答只有一个老师不是你的事情
如果开始问题就用单数，说明你知道就只有一个老师，那还问什么呢
