我在像这样学习 like means“像”in chinese the word "this" here means "the method you use in your study"

我在这样学习 我像这样学习

Hi Sophie, With all due respect, I beg to differ. 我在学和这差不多的 means "I'm studying something like this", which is not the same as "I am studying like this". I believe a better translation, if not the best, will be 我(現在)是這樣子學的.

如果想要说得比较口语化应该说:"我在学和这差不多的." 在和再是有区别的. 再,表示再一次,有重复的意思在里面. 这句话应该用 “在”。
