英语中为什么有时态句子没加助动词,比如：Tony worked in a lawyer's office years ago.这句是不是过去时态,英语时态中一定要加助动词吗
就是没有were啊或者did啊

Answer 1

Tony worked in a lawyer's office years ago.
这句是一般过去时态,判断标志,worked 过去式,以及years ago 时间点.
一般过去时态也可以加助动词,就会产生强调或者十分肯定的语气.比如：
Tony did work in a lawyer's office years ago.
现在完成时态
Tony has worked in a lawyer's office for 10 years.
现在完成进行时态
Tony has been working in a lawyer's office for over 10 years.
过去完成时态
Tony had worked in a lawyer's office for 10 years till yesterday.
将来完成时态
I think Tony will have worked in a lawyer's office by this time of next year.
