I have started the English classes since three weeks ago. 这句话为什么是错的?错在哪?

start是瞬时动词,表示一瞬间的动作,后不能跟since+一段时间
因为一start就结束了,你不能保持开始这个动作,保持三周,同例如：come
这些瞬时动词后,都不能与段时间连用
如：I have come to China for 1 year.(错）
I have been in China for 1 year.(对)
原句应改为 I have had the English classes since 3 weeks ago.
表示三周前持续发生一直延续到现在的动作
have class 上课 after class 下课 in class 在上课

I have started the English classes since three weeks ago. 这句 I have started to study English since two years ago 怎么改 I borrowed the book three weeks ago.同义句转换 I _ _ the book sin i started to teach english three years ago I started to learn English since two years ago.问问大家这句话有语法错误吗 they have learnt English since three years ago.改为同义句 I started learing English three years ago.(对three years ago提 i have taught in this school since three years ago.改为同义句 i h I have had thousands of classes since I started school nine 英语翻译I have had thousands of classes since I started school n 完形填空I have had thousands of classes since I started school n 完型填空（15分）I have had thousands of classes since I started sch
