现在完成时讲解与练习题(含答案)
时态讲解:现在完成时(1)构成:现在完成时由助动词have + 过去分词构成,助动词have 有人称和数的变化。
第三人称单数用has,其余用have.现在完成时的否定式直接在助动词后面加上not、疑问式是把助动词提到主语之前。
以study 为例,其否定式、疑问式和简单回答形式如下:(2)用法:1)现在完成时通常表示在说话之前已经完成的动作或存在的状态。
说话人强调的是该动作或状态对现在的结果或影响。
My daughter has just gone out. 我女儿刚出去。
I’m sure we’ve met before. 我肯定我们以前见过面。
She has arrived. 她到了。
2)表示持续到现在的动作或状态,往往和包括现在在内的表示一段时间的状语连用,如recently, already, just, lately, for…,since…,yet等。
如:I haven’t heard from her these days. 这些日子我没有收到她的信。
We haven’t seen you recently. 最近我们没有见到你。
They have been away for two years. 他们离开已经两年了。
She has been with us since Monday.★注意:1)since和for的区别since后接时间点,如1993,last term, yesterday, the time I got there。
for后接一段时间,表示“长达多久”,如ten years, a while, two days等。
Exercise: 用since和for填空1. Jim has been in Ireland ______ Monday.2. Jill has been in Ireland______ three days.3. His aunt has lived in Australia ______15 days.4. Mary is in her office.She has been there ______ 7 o'clock.5. India has been an independent country ______1974.6. The bus is late.They've been waiting ______ 20 minutes.7. Nobody lives in those houses. They have been empty ______ many years. 8.Mike has been ill ______a long time. He has been in hospital ______ October. 2)表示短暂意义的动词如arrive, leave, borrow, buy, begin, start, die等,在完成时当中不能和表示一段时间的状语连用,因为它们表示的动作不可能持续。

时间状语使用不当
总结词
时间状语使用不当,导致时态使用错误。
详细描述
时间状语是用来表示动作发生的时间的词语。在使用 现在完成时时,学生常常因为时间状语使用不当而导 致时态错误。例如,学生可能会将“yesterday”误 用于现在完成时,因为“yesterday”表示过去时间 ,而现在完成时强调的是对现在的影响或结果。因此 ,正确的时间状语应该是表示一段时间的词语,如 “in the past few years”等。
现在完成时是英语语法中的一种时态,它表示某个动作在过 去已经发生,但这个动作对现在的情况产生了影响或结果。 这个时态强调的是动作和现在的关系,而不是动作发生的确 切时间。
