1.work作“工作”讲时,是不可数名词,故应改成‘job’
2.school前面加一个冠词‘a’,即改为‘a school'
3.Thieves是复数,而does是第三人称单数时才用的谓语助动词.
故把Thieves改为Thief或者把does改为don't
4.语序颠倒
like a waiter是介词短语作后置定语来修饰前面的job的,而不是来修饰you的
故正确的语序应为We have a job like a waiter for you
5.want to do sth.想要做某事
想要某人做某事,则是want sb.to do sth.
故应改为I want you to help me.
