一、现在完成时的被动语态的句式：

现在完成时被动语态的肯定式：have / has been dne
The authr’s new stry has nt been published.
现在完成时被动语态的否定式：have / has nt been dne

语态用来表示主语与谓语之间的关系，它是动词的一种形式。英语中有两种语态：主动语态和被动语态。主动语态表示主语是动作的执行者，而被动语态表示主语是动作的承受者。
思考：什么时候用被动语态？
不知道动作的执行者没有必要指出动作的执行者强调动作的承受者
现在完成时的被动语态的三种用法
主语和谓语是被动的关系：动作已经完成，强调对现在造成的影响或结果表示动作从过去一直持续到现在，有可能还会继续进行用于时间或条件状语从句
1动作已经完成，强调对现在造成的影响或结果His paper hasn’t been handed in yet.(his paper still needs t be handed in)His paper was handed in an hur ag.(the task was finished)I have already bught a cake fr yu.(yu needn’t buy anther ne)I bught a cake fr yu just nw.(just nw I did this fr yu)

2.非延续性动词，如brrw, finish , begin, start, buy, marry, pen, jin 不能在现在完成时中与表示一段时间的状语连用。如要表达相应的意思，要更换动词或时态。He has already brrwed the bk . He hasn’t brrwed the bk yet.He has kept the bk fr a lng time.当动词为非延续性动词时，可与_____或______连用， 但不能与fr 或since 这样引导一段时间的时间状语连用。1.The club has been funded fr five years.
