现在完成时的构成：have/has + 过去分词
现在完成时( The Present Perfect Tense)
1.过去发生或已经完成的动作对现在造成的影响或结果；
2.某些动作的现在完成时可表示过去的某一时间开始并一直持续到现 在（包括“现在”在内）的动作或状态，可以和表示延续的时间状 语连用。表示持续的动作或状态的动词多是延续性动词。
在英语时态中，"时"指动作发生的时间，"态"指动作的样子和状态。
现在完成时的动词变化规则
▪直接在动词原型后面+ed构成过去式，如called▪以不发音e结尾的动词，直接在动词词尾+d构成过去式，如liked；▪以一个辅音字母结尾的重读闭音节动词，双写辅音词尾字母，再+ed 构成过去式，如shpped；▪以辅音字母+y结尾的动词，把y变i，再+ed构成过去式，如studied。
▪见课本最后一页不规则动词表
