Dissertation!

Deadline of the dissertation is early September, but my supervisor will take summer holiday in whole August so I need to some outcomes about my research project within this mouth.
But !!!!!, I have written only less than 1000 words of the fore of the dissertation report!
the word limit is 13,000 words so that there is no worry about exceeding but too much fewer words represents my lack of study amounts...
Today is Wed. and only 3 days for my supervisor leaving from work.
I would not mind that I cannot show my whole dissertation draft to show my supervisor due to the shortage of time to study but I am concerning about that my supervisor being able to understand my dissertation due to the reason I cannot submit it to him.

I need to speed up my study pace and my study continues in August....
