If you are a beginner, I recommend studying just the required liaisons and maybe the forbidden liaison sections, as these are the essentials. 1  If you're more advanced, study all three sections. It may be boring, but your pronunciation and ability to communicate at different levels of formality will improve dramatically.
The United States Navy claims 13 October 1775 as the date of its official establishment, when the Second Continental Congress passed a resolution creating the Continental Navy. With the end of the American Revolutionary War, the Continental Navy was disbanded.
But not before Congress revived the Navy in 1794, authorizing the construction of six warships, including USS Constitution, which remains afloat to this day in Boston Harbor. In 1801 the ruler of Tripoli declared war as part of an attempt to extract increased tribute, and this time the Navy was sent in.
