一个复数的问题.以下两句话哪句对的?Our job is teacher.（因为是同样的职业,所以觉得这句话对）Our

两个句子都不对
job是指职业,只能说 Our job is teaching.而不能说teacher
Those women are very hard - working.
What are their jobs?
They're keyboard operators.（这里的keyboard operator -s为什么用复数表示?）
What are their jobs?改成：What are they?或者 What do they do?
就可以用 They're keyboard operators.来回答
不然这样的一问一答很勉强.
如果硬要解释的话 They're keyboard operators.中的they 是指人而不是指jobs,明白吗?

没有our jobs is XXX
只有we are teather
职业只能说s+v+职业，不能说sb's job is XXX

Our job is teacher。对,主语job是单数，is ，teacher都用的单数形式。
What are their jobs?
They're keyboard operators.这是在特定的环境下问的，主语是they，are用的复数形式，operators自然也加S。

We are teachers. 和 Our job is to teach. 都可以，Our jobs are teachers不对，Our job is teacher也不对。

先说用词
our job is teacher 和 our jobs are teachers
这样的说法，用词就错了
应该是our jobs are teaching，our job is teaching 或 our job is to teach
或 i am a techer，we are teachers，这些说法都对
they are（她们-负数）当然要用 operators
