现在完成时
构成:用法一:表示过去发生的某一动作对现在造成的影响或结果.现在完成时,强调是过去动作与现在的联系,也就是强调现在的影响和结果.have/has

现在完成时和一般过去时的区别:现在完成时:强调这一动作产生的结果对现在的影响或结果,与现在有关。
一般过去时:仅表示在过去某一时刻曾发生过这一动作,与现在无关。他已学英语五年了。HehasstudiedEnglishforfiveyears.

Haveyouhadbreakfastalready?
(表示强调)I’vealreadyhadbreakfast.(常见)=I’vehadbreakfastalready.
2020/12/115注:
有already的句子在时态上并不都是现在完成时,判断时要看该词后是否有动词的过去分词.Eg.She’salreadyeightyyearsold.Itwasalreadyverylate.2020/12/116(2)yet否定句:句末“还(没)”疑问句:句末“己经”Haveyouhadbreakfastyet?Ihaven’thadbreakfastyet.2020/12/117注意:当在肯定句中含already或just,变否定时,在句末加yet。Ihaven’tseenthefilmyet.●
