问题解答：
我来补答
原文看来是没有引用完整的片段,"the extremely profound and thought-provoking meaning "这一句显然是有前文的,但就所引部分没有语法错误.
"Simply designed as the drawing seems to be,it does demonstrate an extensively existing and thought-provoking social phenomenon that……" 同样没有语法错误.此句的谓语是"demonstrate"(does起强调作用)."seems to be"是连词"as"引导的从句中的谓语,而非全句的谓语-- 我猜这是你的困惑.
再问： 你说的太好了，不愧是英语高手，呵呵，可以帮我改一下吗？谢谢你了，怎么改才能比较好呢？
再答： I thought your quote was contextually incomplete. Either that, or you could make the article right by dropping the commas. I.e. "The extremely profound and thought-provoking meaning the cartoonist intends to convey us reveals an extensively existing social phenomenon that it is imperative for us to take drastic measures." - Takes a long breath. :) But this is probably part of what makes the serious formal writing. LOL
