Need proper sentences made up for 1250 vocab words.

I am writing a spelling app and have a vocabulary list of 1,250 words. Each of these words need example sentences -- you know use the word in a sentence. These should be typed up in Notepad or a regular .txt file. These sentences should be simple and easily understood by students in 3 through 7th grades. Don't worry many of the words are simple ones. such as "bark", "barn", "basket", "bath", "bean", "bear", "because", "before", "behind", "better", "bigger", "bike", "birds", "birthday", "blew", "blind", and for 7th graders: "biannual","encouragement","medium","relief","weapon", "bimonthly","engineer","memorize","relieve","wedding", The sentences should not contain very advanced words. Simple is better.
