Let us Dance!

It is terrible that my professor teaching the Introduction to English Literature always lectures too much to dismiss class. Yesterday, she talked for another one hour. The class should have ended at 5:30 p.m., but it lasted until 6:30 p.m. All of my classmates were tired and unhappy. One of my friends and I should have arrived at the event hall at 6:00 p.m. to enjoy a dancing show. Being late, the appetizing desserts were eaten up. We felt depressed and a little hungry. To our joy, the show cheered us up. The brisk music and enchanting Latin Dance seemed to bring me to Central and South America, and I couldn't help dancing with the beat. I also hit on (found out about?) a movie called "Dirty Dancing: Havana Nights," and sincerely recommend you to see it. Let's dance to our heart's content!

Your writing is easily understandable and well organized, you just had a little trouble with tense and missing parts of speech in a few places.
