this is my classroom.the waii are white这个句子 哪里错了

问题描述:

this is my classroom.the waii are white这个句子 哪里错了

this is my classroom. the walls are white(waii-> walls )

This is my classroom, and the wall is white.
两句句子 一定要连词连接,wall是不可数名词 谓语用单数

这是我的课室, 墙壁是白色的

walls

修改如下:
this is my classroom. the wall is white

this is my classroom. the walls are white

写错了……wall
are---is

the wall is white
