It should.keep.you focused in class and help you get a genuine understanding o
f what you are learning.
想請教板上大神們
為何是keep you focused ，因為我翻來覆去想不到的可能原句長什麼樣子？
抑或是因為這邊focused 是oc 當形容詞用修飾you這個o
但為什麼是pp形式而不是V ing 的形式
。
我的小見解請大神們給予指教
Focus v 使集中
The math class focuses us instead of we focus the math class.If so, we focus
“on “ the math class is the correct one to present the meaning which express
上課專心這件事。
Or, we are focused the math class, isn’t it?
So, keep you focused would explain why it is focused instead of focusing.
