一、知识点
一、语法：现在完成时（二）
1.现在完成时与一般过去时的区别：
（1）二者意义上的区别：现在完成时表示过去发生的某一动作对现在造成的影响或结果，强调现在的情况，它与现在有密切的关系。它不是从时间上就是从结果上和现在联系了起来，不能和表示过去的时间状语连用。
一般过去时只表示过去的动作或状态，和现在不发生关系。
（2）时间状语上不同：现在完成时的时间状语有：already, yet, still, ever, s far(到目前为止), recently, these days/weeks/years, since +时间点, fr + 时间段, in the last/past (few years)等。
一般过去时的时间状语有：yesterday ~系列；last ~ 系列；~ag系列；in + 过去时间；及上下文暗示或其他一些特殊的时间状语

yet“已经”与现在完成时连用，用于否定句或疑问句中，位于句末，可与nt连用表示“还没有”
ever“曾经”用于现在完成时中，用于否定句、疑问句、比较结构或带if的句子中
still“至今还，现在仍然”用于肯定句中
Eg: (1) I have already seen the film.
我已经看过这部电影了。
