语法 Grammar in use
现在完成时
（1）在英语中，现在完成时主要用于以下两种情况：或者表示在过去不确定的时间里发生的并与现在有着某种联系的动作；或者表示开始于过去并持续到现在的动作。本课中萨姆所面临的是第1种情况，正是因为他吃了饭，喝过了咖啡，也休过假，因此他谢绝了汤姆的邀请，并表示今年已无可能再次休假。
（2）现在完成时在汉语中常用“了”、“过”或“已经”来表示。
（3）现在完成时由 have／has+ 过去分词构成，单数第 3人称用
has，其他人称皆用have。规则动词的过去分词与过去式相同，而不规则动词的过去分词则无统一的规律可言，需特别加以记忆。
（4）一般现在完成时通常与表示不确定的时间副词或短语连用如 just, already, before, never, ever, twice, three times等。
