解题思路： 如下
解题过程：
I started to practice the guitar since three hours ago 用for改写 是不是还要改延续性动词？
同学你好，你的这个句子应该改为：I started to practice the guitar three hours ago . 和“since+时间点”，“for+时间段” 连用的动词都必须是延续性动词。因此这个句子还可以改写为：
1.I have been practicing the guitar for three hours.
2.I have been practicing the guitar since three hours ago .
最终答案：略
We began to study hear 2 year ago.改为同义句 用since或for转化为现在完成时的句 because/since/as/ for 用since,for填空 since and for since/for 用法 比较since和for for,since有什么区别 用since和for填空 since和for的区别 用since和for填空. since for的具体用法 for和since的用法
