【现在完成时的构成】 现在完成时是由“助动词have / has + 过去分词”构成的，其规则动词的过去分词构成与过去式相同，不规则动词的过去分词则需加强记忆。如：
　　I have just cleaned my clothes． 我刚洗过衣服。
　　My brother has done his homework already. 我的弟弟已经做完他的作业了。
　　友情提示：在现在完成时的各种结构中，have, has均为助动词，无实际意义，只起构成时态的作用，不可省略。当主语是第三人称单数时助动词用has，其余人称一律用have。
　　【现在完成时的句式】 1. 否定句式：现在完成时的否定句式是“haven't （hasn't）＋过去分词...”。如：
　　I have not seen the movie yet. 我还没看这部电影。
　　2. 一般疑问句：Have（Has）+主语+过去分词...？ 如：
　　—Have you finished the work？你已经做完这项工作了吗？
　　—Yes, I have. 是的，我已经做完了。（No, I haven't. 不，我还没有做完。）
　　—Has she arrived here？她已经到这儿了吗？
　　—Yes, she has. 是的，她已经到了。（No, she　　hasn't. 不，她还没有到这儿。）

  Thanksgiving Day is the most truly American of the national Holidays in the United States and is most closely connected with the earliest history of the country.

  In 1620, the settlers, or Pilgrims, they sailed to America on the May flower, seeking a place where they could have freedom of worship. After a tempestuous two-month voyage they landed at in icy November, what is now Plymouth, Massachusetts.
