But the part they play in actually making the car is so small that they...
But the part they play in actually making the car is so small that they can never say:I have made something!

但是他们在制造汽车方面所起的作用实际上很小,以至于他们始终不能说:我已做了某件事.
play part in在^方面起作用.能讲解下句子结构吗?the part是主语,they play in actually making the car 是定语从句,修饰part,is是系动词,so small是表语,that they can never say是结果状语从句
