Keep pressing the green flag for the sentence to regenerate.
This project is a simple generator of sentences- so far, the only thing it can do is say "[subject] [am/is/are] [article] [man/woman/person/etc.]" But I hope to continually update this- perhaps it will ask you to translate the sentences it generates. Ultimately, I think a project like this will help people learn languages (like how duolingo.com does). I hope to start projects teaching Chinese, using this "synthetic sentence generating" approach, as Duolingo doesn't teach Chinese, and websites that help you (easily) learn Chinese are few and far between.
