supposed to be是什么意思

题目

supposed to be是什么意思
全句:I don't know what the building in the picture on the front is supposed to be, since AS YOU KNOW I don't speak or read French. At all.
麻烦大家把全句也翻译了吧..然后帮我解释一下supposed to be

答案

supposed to be这里的be不应该和前面是一体的,简略一下,就是what the building be,建筑物是什么样的,in the picture on the front 这个只不过是来修饰building.而is supposed to可以理解为是情态动词,比如说,shuold,可以换成这个词,这样就容易理解了吧.这只是我自己的理解...is supposed to是 应该,被期望的意思.翻译出来,我不知道前面图片上的建筑物应该是什么样的.正如你所知道的,因为我根本就不懂法语.
