How can I make this surface look continued

Hi,

I am new to rhino. I have a model that has some part looks not smooth.
Tried every command I know and look the tutorial videos but still can’t make it look smooth, and fit the other parts of the model at the same time. I tried “sweep 2”, “surface network”, “surface network with different kind of profile curve”,“blend surfaces” but non of them give me a good result.
Is there any way can help me achieve a smoother surface here?
Also, when I use eMap to look at the model, some part looks broken, but it looks fine when I am in the shape mode. Is that normal or something wrong with my model?
