M2U1现在完成时与完成进行时


M2U1 Tales of the unexplained
Grammar Present perfect tense and present perfect continuous tense 教学重难点:the usage differences between present perfect tense and present perfect continuous

tense 教学目标:teach the Ss to use the two correctly。 方法设计: 一,现在完成时(A)
1.现在完成时的构成 现在完成时的构成形式是“have / has +过去分词”。现在完成时常被称为“与现在有联系 的过去”,因此它不能与明确的过去时间状语连用。 I haven't seen much of her lately. 我最近不常见到她。 2.现在完成时的用法 ①表示结果的现在完成时 在完成时着眼于过去的动作对现在产生的结果或影响 I have bought a pen. 我买了一支笔。(结果:I have a pen now.) ②强调过去某一时刻到说话时这段时间中的经历。 I have visited Beijing at least ten times. 北京我至少访问过十次了。 ③表示一个动作或状态从过去某时开始,持续到现在,可能要继续下去。 I have lived here for more than thirty years. 我已在这儿住了三十多年了。(也许还会继续住下去) 注意:(B) 现在完成时的“未完成”用法既可用于动态动词 (主要是持续动词) , 也可用于状态动词, 但它一般不适用于表示短暂动作或位置转移的动词, 如: open, break, go, come, arrive, leave 等。如用这类动词表示“未完成”,通常只限于否定结构。 I haven't seen a film for weeks. 我已经好几个星期没看电影了。 3.现在完成时的时间状语 ① a. 不确定的过去时间状语:already, yet, before, recently, lately 等 b. 频度时间状语:often, sometimes, ever, never, once, rarely 等 c. 包含现在时间在内的时间状语:now, just, today, this morning, this week, this year 等 比较:already 和 yet 用法上的区别(B) already 常用于肯定句,置于句中。yet 常用于否定句和疑问句,置于句末。但 already 有 时也可用在疑问句中暗示惊讶的心情。 ②表示具体的过去的时间状语不能与“未完成”用法连用。 与其连用的往往是指一段时间 的状语以具体表示某一动作或状态持续了多久。 a. since + 具体时间,表示动作或状态从何时开始 b. for + 一段时间,表示动作或状态持续了多久 c. until now, up till now, so far, up to the moment
