Tim usually have lunch at school.There is a clothes shop on the three floor.

问题描述:

Tim usually have lunch at school.There is a clothes shop on the three floor.

第一个 注意单复数 has lunch
第二个 注意序数词 third floor

Tim usually haS lunch at school. (have 改成 has 和第三人称 TIM 一致.)
There is a clothes shop on the THIRD floor. (three floor 改成the third floor表示第三层楼。)

正确的句子如下:
第一句:Tim ususlly has lunch at school 主语是Tim, 后面应该第三人称单数
第二句:There is a clothes shop on the third floor.

不对,应为Tim usually has(单三)lunch at school

has lunch
third floor
