my father and mother are look at a picture
问题描述：
my father and mother are look at a picture
答
my father and mother are look at a picture 。
这句话是不对的。有两个谓语，在英语中一个句子只能有一个谓语。有了be动词就不能再有实义动词了。
这个句子应该去掉 are 或者 把look 改为looking（这时是进行时).
答
my father and mother are looking at a picture
这句话应该用现在进行时。
答
应该：my father and mother are looking at a picture
答
