段落是英文演讲稿的一部分,除了希望能够修改掉明显的语法错误外,还希望能将语句变得更口语化一点.

Hello,my name is ...,and my case study is about.
As a customer,better service and lower price,which one do you think is more important?This has been an controversial topic for a long time.
That is why I decided to do this case study.
And this paper is presented in the position of the enterprise and from the view of strategy managers.
This case concerns (is mainly about) marketing capabilities (没太看懂你想表达啥)
If you search on wiki,you can find a accurate but complicated definition which is
Marketing capability is one of the efficient useful strategies which companies use to expand their businesses and operations.
Also,they need this marketing capability to learn customers' expectation and requirement in order to gain success in the marketplaces.
大略改了一下,有些地方没太理解你的意思,就按照自己的理解改了下,你参考下看看.
