At the end of this month, lilian will get lasik surgery to permanently correct her  vision.

what is the signal word or phrase that indicates the need for future-tense verbs?

At the end

Explanation:

By saying "at the end" it indicates that it has not happened yet, but it is going to happen. Which in turn means you need to use future-tense verbs instead of present.

no its not a run on sentence however i think you meant wet suits not sours also a run on sentence would be like surfers surf all winter long in southern california by using wet sours to keep them warm and the live their all year long  

hello!

"hidesato showed not the least sign of fear. he tried to calm the dragon king: don't be afraid. i shall surely kill the centipede."
