Answer 1

1. through是介词，后必须接名词或动名词
Through the study on these features...（此处study是名词）
Through studying these features...（此处study是动词）
2. use应改为using，这里的动词不是谓语动词，不可以用原形，应该用动词的ing形式作为后置定语来修饰。
3. 理由同2，contain应改为containing。
4. A rhetorical question is a kind of question which emphasizes the obvious answer to the question asked rather than for accessing information.
5. accepted
6. is used；when translated
