语法（Grammar）
一、现在完成时的构成
现在完成时的构成:助动词 have (has)+动词的过去分词 过去分词的构成方法如下 : A:1.一般情况下，直接在动词原形后面加 –ed. worked answered obeyed wanted 2.以不发音的 -e 结尾的动词只加 –d. moved hoped divided
3.字尾是辅音八行书写字+y的动词。则将y改i加ed. studied tidied satisfied 4.以重读闭音节结尾的词，这些词的末尾只有一个辅音字母时，双写这个辅音字母，再加 –ed.
stopped regretted dropped B: Learn the verb list on P122.
二、现在完成时的用法
1、现在完成时的 "完成用法"
现在完成时的 "完成用法" 指的是动作发生在过去某一时刻并已结束，但该动作对现在产生了影响，与现在情况具有因果关系。 例如: He has turned off the light. 他已把灯关了。
( 动作结束于过去，但说明的是现在的情况 -- 灯现在不亮了。)
现在完成时 "完成用法" 的特点是动作不延续，因此，该时态只能与表示不定的过去时间状语 ( 如: already ， yet ， before ， recently 等 ) 、频度时间状语 ( 如: never ， ever ， once 等 ) 、包括现在时刻在内的时间状语 ( 如: this morning / month / ， today 等 ) 连用。 例如: Have you found your pen yet ,你已找到你的钢笔了吗, 2、现在完成时的 " 未完成用法 "
现在完成时的 " 未完成用法 " 指的是动作开始于过去某一时刻，一直延续到现在，或可能还要继续下去。
例如:1. He has lived here since 1978/he moved here. 自从 1978 年以来，他一直住在这儿。 ( 动作起始于 1978 年，一直住到现在，可能还要继续住下去。)
2. I have been in the army for more than 5 years. 我在部队已经呆了五年多了。 ( 动作开
始于 5 年前，一直延续至今，有可能还要继续下去。)
此种用法的句中常需一个表示一段时间的状语 ( 由 since 或 for 引导 ) ，或表示与现在时刻相连的时间状语 ( 如: up to now ， so far 到目前为止 ) 等。例如: I have heard nothing from him up to now. 到目前为止我没有他的任何消息。
