三、语法㈠现在完成时
⑴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。

⑵现在完成时在汉语中常用“了”、“过”或“已经”来表示。

⑶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 。

规则动词则无统一的规律可言，需特别加以记忆。

⑷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。

例：The car has arrived.汽车已经到了。

He has travelled over many countries.他到很多国家旅游过。

变疑问句：Has he travelled over many countries.
㈡动词变过去分词的规则变法：
1、直接在动词后面加ed finished
2、以不发音e结尾的动词直接加d arrived
3、以辅音字母加y, 把y变i加ed studied
4、辅元、辅且重读，双写词尾辅音字母加ed stopped
5、不规则变化详见表
