现在完成时的“完成用法”和“未完成用法”

其中 have / has 为助动词,它的否定和疑问句形式全部由 have / has 进行变化。
例如: He has finished his homework.他已经做完了家庭作业。

否定句：____________________________________________________.
一般疑问句：________________________________________________
对划线部分提问_____________________________________________
2、现在完成时的"完成用法"
A、定义：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。)
B、特点：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 ／year...，today等)连用。
例如： Have you found your pen yet？ 你已找到你的钢笔了吗？
例如：所给动词的适当形式填空。
1. Would you like some bananas -No, thanks. I_______ （ eat）one already.
2. Mr White came to our school in 2008, and since then he_______（teach） us English
