argument总结段第一句是抽象点好还是具体点好

ttangUID: 3375356

比如，我发现自己第一句会写成这样：
To sum up, whether the recommendation could achieve desired outcome is dubious as it stands.
但是有的同学说，这个像套话，具体点好
大概是这样：
To sum up, whether the recommendation could help attract more customers and better compete with Regal Books is dubious as it stands.
可是我觉得这样有有点重复，因为“attract more customers and better compete”这个题目里已经有了，前文也重复过……

求指教～
