我知道the的用法有时候真的不怎么把握的准例如。in the morning ,mr.sawyer goes to work为什么work前年不加the还有It is 9.o'clock.the children are going into class.it is 4.0 o'clock.the children are coming out of class.按理说class前面要加the啊!还有you are the best为什么这句best要加the啊!是不是形容词最高级前要加最后一句we are enjoying our lunch.这句话该怎么理解啊!enjoy是玩的开心的意思,难道我们把我们的午餐玩的开心吗?各位帮帮我理解
