3、完成时的判断依据二、过去完成时的判断依据1.1.由时间状语来判定由时间状语来判定一般说来,各种时态都有特定的时间状语。与过去完成时连用的时间状语有:一般说来,各种时态都有特定的时间状语。与过去完成时连用的时间状语有:(1 1)by+by+过去的时间点。过去的时间点。如:如:I had finished reading the novel by nine oclock last night.I had finished reading the novel by nine oclock last night.(2 2)by the end of+by the end of+过去的时间点。过去的时间

8、主、从句表示的动作紧密相连,则主、从句都用一般过去时。了动作的先后关系,若主、从句表示的动作紧密相连,则主、从句都用一般过去时。如:如:Where did you study before you came here Where did you study before you came hereAfter he closed the door,he left the classroom.After he closed the door,he left the classroom.(3 3)表示意向的动词,如)表示意向的动词,如 hope,wish,expect,think,intend,me

15、侧重对现在产生的结果或造成的影响,与现在现在完成时表示的动作发生在过去,但侧重对现在产生的结果或造成的影响,与现在有关,其结构为“助动词有关,其结构为“助动词 have(has)+have(has)+过去分词”;过去完成时则是一个相对的时过去分词”;过去完成时则是一个相对的时态,它所表示的动作不仅发生在过去,更强调“过去的过去”,只有和过去某时或某动态,它所表示的动作不仅发生在过去,更强调“过去的过去”,只有和过去某时或某动作相比较时,才用到它。试比较:作相比较时,才用到它。试比较:I have learned 1000 English words so far.I have learned

18、returned home returned home 之前去了哪些地之前去了哪些地方,即“过去的过去”)方,即“过去的过去”)五、过去完成时与一般过去时的区别五、过去完成时与一般过去时的区别虽然这两种时态都表示过去发生的动作或存在的状态,但在使用时应注意以下几点:虽然这两种时态都表示过去发生的动作或存在的状态,但在使用时应注意以下几点:1.1.时间状语不同:过去完成时在时间上强调“过去的过去”;而一般过去时只强调过去时间状语不同:过去完成时在时间上强调“过去的过去”;而一般过去时只强调过去某一特定的时间。试比较:某一特定的时间。试比较:They had arrived at the stat
19、ion by ten yesterday.They had arrived at the station by ten yesterday.They arrived at the station at ten yesterday.They arrived at the station at ten yesterday.2.2.在没有明确的过去时间状语作标志时,谓语动词动作发生的时间先后须依据上下文在没有明确的过去时间状语作标志时,谓语动词动作发生的时间先后须依据上下文来判断:先发生的用过去完成时,后发生的则用一般过去时。如:来判断:先发生的用过去完成时,后发生的则用一般过去时。如:She wa

22、 read an evening paper.I(had)called her before I left the office.I(had)called her before I left the office.重点重点英语中,已经有了一个过去一般时表示在过去发生的动作,为什么还有过去完成英语中,已经有了一个过去一般时表示在过去发生的动作,为什么还有过去完成时呢?时呢?要记住:过去完成时的关键概念是:假设在过去发生了两件要记住:过去完成时的关键概念是:假设在过去发生了两件(或以上或以上)的事件,一的事件,一件是件是 A A 事件,另一件是事件,另一件是 B B 事件,如果事件,如果 A A、
23、B B 两个事件几乎是同时发生的,那就用一般过两个事件几乎是同时发生的,那就用一般过去时;但是,如果去时;但是,如果 A A、B B 两个事件不是同时发生的,怎么办呢?那就是:哪个事件先发两个事件不是同时发生的,怎么办呢?那就是:哪个事件先发生,就用过去完成时;哪个事件后发生,就用过去完成时。在上面的假设中,如果生,就用过去完成时;哪个事件后发生,就用过去完成时。在上面的假设中,如果 A A事件先发生,事件先发生,A A 就用过去完成时;如果就用过去完成时;如果 B B 事件先发生,事件先发生,B B 就用过去完成时;而不管两件就用过去完成时;而不管两件事是用什么样的时间状语或其它形式表示的。
