in the derset 还是on the desert
1.You may think there is only sand in the desert(沙漠) of the world
2.These animals live on the desert plants for their food and do not need any water.
这里为什么第一句用in the desert 第二句用on the desert?
还有第二句里plant是动词么?

in the derset 还是on the desert1.You may think there is only sand in the desert(沙漠) of the world2.These animals live on the desert plants for their food and do not need any water.这里为什么第一句用in the desert 第二句用on the deser
第一句话,“也许你会认为在世界上沙漠里面只有沙子”,这里的in只是一个介词,并没有和后面的the desert形成什么搭配.只是在表示前文的sand是在desert里面的.
第二句话,“这些动物以沙漠中的植物为食而且不需要任何的水”,这里的on适合前文的live形成固定搭配,即live on,意思是“以.为食”,“靠...生存”,这里的plant不是动词,而是名词,表示植物.
所以两个句子中的in和on都没有和desert搭上什么关系,只是一个做单纯的介词,另外一个是live on的固定搭配.

第一句 ON the desert
第二句 live on是动词 就是依靠沙漠里面的植物(the desert plants )
