表示过去发生或已经完成的某一动作对现在造成的影响或结果，或从过去开始一直延续到现在的动作或保存的状态。
◆肯定式：主语 + have / has + 动词过去分词 + 其它。如：They have spent all their mney, s they have t walk hme. 他们把所有的钱都花光了，只好步行回家。[注意] 这里的have / has是助动词，没有具体意义。当主语是第三人称单数时，助动词用has，其余人称用have。
◆否定式：主语 + have / has + nt + 动词过去分词 + 其它。如：She hasn’t travelled n a train yet. 她还未坐过火车旅行。[注意] have nt, has nt的缩略式分别为haven’t, hasn’t。
◆一般疑问式：Have / Has + 主语 + 动词过去分词 + 其它？肯定回答: Yes, 主语 + have / has. 否定回答: N, 主语 + haven’t / hasn’t. 如：— Have yu ever made dumplings?      你曾包过饺子吗？— Yes, I have.      是的，我包过。
◆特殊疑问句：疑问词 + have / has + 主语 + 动词过去分词 + 其它？如：Wh has brken the windw? 谁打破了窗户?When have yu finished yur hmewrk? 你什么时候完成的作业?
规则动词①动词后加-ed，如： wrk — wrked，ck — cked。②以e结尾的动词加-d，如： live — lived，like — liked。③以“辅音字母+y”结尾的动词将y改为i再加-ed，如： try — tried，carry — carried。④末尾只有一个辅音字母的重读闭音节词，先双写这个辅音 字母，再加-ed，如： stp — stpped，drp — drpped。
(2)不规则动词     不规则动词的过去分词形式需要特殊记忆，如： see — seen，be — been，take — taken
already, just, yet, never, ever基本用法
already（已经）用法：表示动作在说话之前已经完成，常用于肯定句和疑问句。位置：通常放在 have/has 之后、过去分词之前。例句：I have already painted the huse. 我已经粉刷了房子。Has she already left? 她已经离开了吗？
just（刚刚）用法：表示动作刚刚发生，强调时间很近。位置：放在 have/has 之后、过去分词之前。例句：He has just arrived hme. 他刚刚到家。We have just watched that mvie. 我们刚看完那部电影。
yet（还，已经）用法：在疑问句中表示“已经”，用于询问是否完成。在否定句中表示“还（没）”，说明动作尚未发生。位置：通常放在句末。例句：Have yu dne yur hmewrk yet? 你做完作业了吗？I haven’t seen that film yet. 我还没看那部电影。
never（从未）用法：表示从过去到现在从未发生过，强调“一次也没有”。位置：放在 have/has 之后、过去分词之前。注意：句子本身已是否定含义，不再加 nt。例句：She has never been t Beijing. 她从没去过北京。I have never read that bk. 我从没读过那本书。
ever（曾经）用法：多用于疑问句，询问过去的经历；也可用于否定句或某些肯定句（如最高级后）。位置：放在 have/has 之后、过去分词之前。例句：Have yu ever tried Japanese fd? 你吃过日本料理吗？This is the best bk I have ever read. 这是我读过最好的书。
