三天不练手生✍
Let's start!
✅瞬间动词与延续性动词认识
✅瞬间动词与延续性动词互换使用
✅强化练习
基本认识
1.瞬间动词
也称为【终止性动词】和【非延续性动词】。顾名思义，这类动词所表示的动作在瞬间就可以完成，没有延续下去，动作开始到结束的时间很短。通常瞬间动词表示的是一次性动作或者动作的相应结果。不能和since/for连用。
如：jump/die/ leave/ go/ /see/ hear/ come/ borrow/ begin/ close/buy等等
2.延续性动词
又称为【持续性动词】，这类动词表示可以持续的动作，或者状态。动作可以延续一段时间，所以这些动词就可以和since与for连用。
如：stay/ keep/ be/ rain/ have / sleep/ work等等
⏺️来看看例句：
I have borrowed the book for five days.（我5天前就借了这本书。）
🙋🖕这句话大家觉得是正确的还是错误的？
⚠️⚠️⚠️错误的❎
【borrow】是瞬间动词，能用于现在完成时，但不能与since/for连用。
✍那么可以怎么修改呢？
【1】改成延续性动词“keep”
borrow➡️keep
I have kept the book for five days.
【2】改变时态，改成“一般过去时”
I borrowed the book five days ago
⏺️再看看一句：
She has arrived here since three hours ago.（她三个小时前就已到这里了。）
👆同样这句话大家觉得是正确的还是错误的？
⚠️⚠️⚠️错误的❎
【arrive】是瞬间动词，能用于现在完成时，但不能与since/for连用。
✍更改
【1】arrive➡️be
She has been here since three hours ago.
【2】一般过去时
She arrived here three hours ago.
瞬间动词和延续性动词转换
✅现在完成时肯定句中，瞬间动词作谓语时，不能和since/for表示一段时间的状语连用。
✅记住瞬间动词可以用于现在完成时，只能不能和since/for连用。
✅瞬间动词可以替换为延续性动词，替换为延续性动词后，可以和since/for连用。
看下面这句话：
“他已经去世三年了。”
去世，对应的动词，【die】。对照上表，die是瞬间动词，转换为延续性动词是be dead。如果要使用谓语动词【die】，那么就要用一般过去时;如果要和since/for连用，【die】就要替换为【be dead】。
所以这句话对应的表达有5种：
（1） He died three years ago.
【一般过去时，标志词three years ago】
（2） He has been dead for three years.
【现在完成时，标志词for+一段时间】
（3） He has been dead since three years ago.
【现在完成时，标志词since+一段时间】
（4） It is three years since he died.
【It is +一段时间+一般过去时从句】
（5） Three years have passed since he died.
【一段时间+have/has passed+since+一般过去时从句】
✍练习：句子中的瞬间动词需要改为延续性动词，用适当的形式把句子补充完整。
1.He died 10 years ago.
He ______________ for 10 years / since 10 years ago.
【has been dead】
2. He borrowed the book 2 weeks ago.
He _____________the book for 2 weeks.
【has kept】
3. He bought the motorbike a month ago.
He ___________the motorbike for a month.
【has had】
4. He arrived here three days ago.

【has been】
6. He left here 2 years ago.
He ____________from here for 2 years.

7. The film began 30 minutes ago.
