Question

we have been friend for 20 years

两个英语问题
一下这连个句子有什么不同
we will arrived
we will be arrived
arrive或arrived后面好用加什么其他成分吗?
we have been friends for 20 years.
he had been in London for 2 years.
句子一和句子二的时态怎么分析?

Answer 1

第一个问题应该是问We will arrive和We will be arriving的区别吧?要不然给出的两个句子就是错误的.
第二个问题：We have been friends for 20 years 是现在完成时,表示从过去的某个时刻开始到现在这个状态或动作持续了多长时间.本句中表示“我们已经是20年的朋友了”这种状态的持续.而He had been in London for 2 years.是过去完成时,上下文中肯定得有过去时的某种时态来做对比.因为过去完成时表示的是“过去的过去”,也就是说得有一个过去的时间表示动作或状态截止的时刻才行.比如说可以加上By last month,he had been in London for 2 years.“截止到上个月,他已经在伦敦呆了两年了.”
