这里的picture不是指实体的照片或图画，而是对人或事物的描述或意念。例句：

1）What you see in the movies isnt a realistic picture of what love is about.(看韩剧爱情故事的女生注意了！生活中能找到韩剧的男主角吗)

2）I really dont have a clear picture of what Sam does at work.(希望你的老板不会这样对你说哈)

Jimmy老师说： I really dont have a clear picture of what my wife does all day long.

"a big picture",有天跟马来西亚籍的老师讨论课程计划的时候，他用到这个词。We just want to give the students the big picure of it.we neednt tell them every detail.

当一个人喋喋不休说某个事情没完的时候，你除了可以问：what's your point?也可以用这个：please give me the big picture of it.

另外paint a picture of sth:描绘，描述

eg.

1)The report paints a grim picture of life there.

那则报道把那里的生活描绘得很凄惨。

2)He went on to paint a rosy picture about how much has already been accomplished.

他继续描绘着已经取得多大成就的美好画卷

"a big picture",有天跟马来西亚籍的老师讨论课程计划的时候，他用到这个词。We just want to give the students the big picure of it.we neednt tell them every detail.

因为我要给他的研究生上一个软件课程，要用英文讲，因为有些是外国学生。我当时脑子在想，哪个词是”纲要“呢，这词穷呢，他说了：en，a big picure.
