1、Unit 3 语法篇_学生通过本讲学习，能够掌握本单元的重点词汇句型，并在综合能力上有一定的拓展。在完成时的结构现在完成时由“have/has+过去分词”构成，主要有两个含义： 表示动作发生在过去，但与现在的情况有联系，有时无时间状语，有时和一些表示不确定的过去时间状语连用，如：many times，just，yet，ever，never，just，already，before，so far, by now等连用。表示从过去某一时间开始一直延续到现在并还可能继续延续下去的动作，用于延续性动词，且句中常带有表示一段时间的时间状语，如：since + 时间点/从句，for two months,

2、so far等。 1）现在完成时和一般过去时都能表示过去发生过的动作，但现在完成时表示过去动作对现在的影响，并且表示这一动作已完成或还可能继续下去；2）而一般过去时与现在的情况没有联系，仅表示过去的动作，且这一动作到说话时已终止。因此现在完成时不能与表示明确的过去时间如：in1949，yesterday，last week等的状语连用，并且用when或where对这些时间和地点状语提问时，一般只用一般过去时。三、在“it is first/second.time that.。”或在“it/this/that is the +最高级+名词+that.。”结构中，that从句中的动词常用现在完成时

3、；在“it + be .+since从句”这一结构中，be可用一般现在时或现在完成时，since从句一般用过去时。1. - How is your grandfather?- Oh, he _ for half a year.- I am sorry to hear that.Ahas died Bdied Chas been dead Ddies2.

5、r half a year 为一段时间。故C项正确2. 题干中的时间状语for nearly three weeks必须和延续性动词连用。而A、B、C三项均为非延续性动词,故选D项3. 处要求动词具有持续性。排除C、D两项。如果选B，Sanya前应有in，故排除B选A。4. 本题考查延续性动词。buy, receive和borrow都是短暂性动词,不能与时间段连用。四个选项中只有A才能与about three weeks连用,故选A.。5.how long应和持续性动词连用,在所有选项中,只有had是持续性动词，故选C基础演练一 A句型转换1 Susan has watched the fil
