Mary wants to be an actor 改为一般疑问句Is Mary want(s) to be an actor?要不要s 为什么啊
问题描述：
Mary wants to be an actor 改为一般疑问句
Is Mary want(s) to be an actor?
要不要s 为什么啊
答
你写错了。。
want 是实意动词，改为一般疑问句要借用助动词，应该是Does Mary want to be an actor?所以不存在加不加s的问题
答
Does Mary want to be an actor?
答
Does Mary want to be an actor?
因为want是实义动词,变一般疑问句时,要用助动词do,而Mary是第三人称单数,所以do要变为does.若句子中有be动词,变一般疑问句时,把be动词移到句首,其他不变,最后加一个问号.如：She is a teacher.变一般疑问句为Is she a teacher?
答
Does Mary want to be an actor?
