not to nitpick, but my English comp teacher taught us to never start a sentence with a preposition, and to be careful with the use of commas. Wracked? Racked? What has happened to Wikipedia?
The rule against starting sentences with prepositions is often attributed to 18th and 19th-century grammarians who tried to apply Latin grammar rules to English. Modern linguists generally reject this as an unnecessary and artificial constraint.
