語(yǔ)法是英語(yǔ)學(xué)習(xí)過(guò)程中最難掌握的知識(shí)，要想提高自己的英語(yǔ)學(xué)習(xí)效率，積累和掌握很重要。下面是關(guān)于英語(yǔ)時(shí)態(tài)知識(shí)，大家可以作為學(xué)習(xí)的參考。

【基本用法】 “過(guò)發(fā)現(xiàn)影”--- 表示過(guò)去發(fā)生，對(duì)現(xiàn)在造成了影響。

【重難點(diǎn)】 延續(xù)性與非延續(xù)性動(dòng)詞的用法

什么時(shí)候才必須用延續(xù)性動(dòng)詞? 出現(xiàn)how long, for+時(shí)間段, since+時(shí)間點(diǎn)

非延續(xù)性動(dòng)詞轉(zhuǎn)化
