ihavejustheardthenews 我刚听到消息 astronautshavealreadybeentothemoon 宇航员已经去过月球了 wehavejuststartedtoexploreotherplanets 我们才刚刚开始探索其他行星 just 刚刚 already 已经 两者都用于肯定句中 一般置于have has之后 否定句中则用yet 表示 还 未 如 thescientistshavenotheardfromityet 科学家还没有收到它发出的信息 manhasnotdiscoveredanylifeinspaceyet 人类尚未在太空中发现生命 常与现在完成时连用的副词 肯定句 疑问句和否定句 yet常置于句末 already never ever just一般置于助动词have has之后 过去分词之前 already just ever yet never already just ever ever yet never a haveyou b yes no usingalready just ever yet never 现在完成时与一般过去时 现在完成时表示该事件是在现在之前的某一个时间里发生的 重点在于强调这一动作与现在的影响一般过去时只表示过去的某一具体时间发生的事情 ihavejustbeentolondon iwenttherelastmonth 我刚去过伦敦 是上个月去的 ihavealreadyfinishedmyhomework ifinisheditanhourago 我已经写完作业了 一个小时之前完成的 a wherehaveyouputmybook ican tfindit b iputitonyourdeskyesterday 当a问对方把自己的书放在何处时 他在意的是书目前在哪儿 故用现在完成时 b的回答着重的是当时的动作 故用一般过去时 无明确过去时间状语时 判断使用现在完成时还是一般过去时的标准是 看该行为是否对现在有影响 即该句强调或在意什么 着重点就在那里 a wouldyouliketogoandseethefilmwithmetonight b sorry i italready see practise haveseen 注 word文档点击此处链接 中考链接
