6、一次考试及格。 6.表示愿望、打算一类的词,如:hope,expect,mean,intend,want,think,suppose等,其过去完成时表示过去未曾实现的愿望或意图。 I had hoped to see more of Shanghai. 我本希望在上海多看看。(但未能如愿),I had meant to help you,but I was too busy at the moment. 我本想帮你的,但当时确实太忙了。 I had thought you would come tomorrow. 我原以为你明天才来呢。 二、过去完成时同现在完成时及一般过去时的区别,1.过去完

7、成时与现在完成时的区别 现在完成时表示的动作发生在过去,以现在的时间为基点,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have(has)过去分词”;过去完成时则是一个相对的时态,以过去时间为基点,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。,比较:I have learned 1,000 English words so far. 到目前为止我已经学会了1000个英语单词。 I had learned 1,000 English words till then. 到那时为止我已经学会了1000个英语单词。 2.过去完成时与

8、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:,(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某一特定的时间。 比较:They had arrived at the station by ten yesterday. 他们昨天十点之前就已经到达车站了。 They arrived at the station at ten yesterday. 他们昨天十点到达车站。,(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来判断:先发生的用过去完成时,后发生的则用一般过去时。 She was
