^我的想法
答
问某人的职业的话，最好还是用 do来提问
Does your sister work in a computer company?
Yes she does .
答
Does your sister work in a computer company?
Yes,she does.
is 变成 Does working变成work
就是2个改错了
这里疑问句的事态错了，一般不用现在进行时回答的（因为不是表示正在进行的动作），应该用一般现在时
答
这个疑问句应该用一般现在时而不是现在进行时，时态有错，回答是用的一般现在时回答的，就改问句就可以了
is改为does
working改为work
答
应该是Does your sister work in a computer company? 问工作不能用进行时（我的记忆中）
答
Is your sister working in a computer company?
No,she isn't.
