4、 give me a lift. 我不知你能否让我搭一下车 【注】一般过去时也有类似用法,但比较而言,用过去进行时显得更客气,更不肯定。能否让我搭一下车。第八张,PPT共四十二页,创作于2022年6月 3. 过去进行时表示感情色彩与现在进行时相似,过去进行时也可表示满意、称赞、惊讶、厌恶等感情色彩,也通常与 always, forever, continually等副词连用。 如: They were always quarrelling. 他们老是吵架。 第九张,PPT共四十二页,创作于2022年6月 4. 动词be的过去进行时也可表示过去一时的表现或暂时的状态。 比较: He was fr
