Tom likes to work in different companies.Evidence shows that he has not held on to the same job for any length of time.
汤姆喜欢换工作.有证据表明,他每一个工作都干不了多久.让我感到困惑的是：that 引导的从句,has not held on to the same job,意思是不能在同一份工作上坚持,可是for any length of time，短语的意思是“短暂而已”我觉得不是很通，如果后面改为：for a long time.我觉得更通顺一些.for any length of time一（小）段时间 eg: The patient cannot endure chemotherapy for any length of time. 病人对于化疗一会儿也不能忍受。 While sitting for any length of time, take frequent standing breaks to alleviate atrophy of the hamstring muscles.坐了一段时间之后，时不时的站起来活动一下，可以避免腿部肌肉萎缩。
