小知识

A tract is a large, open piece of land — like that tract of farmland you bought when you decided your dream in life was to raise llamas. Tract is also a word for a short pamphlet or booklet, like that tract you recently read entitled “The Care and Feeding of Llamas.”

In addition to referring to areas of land and small booklets, the word tract can describe complicated systems or structures in the body. If you were to unwind your intestine, an important part of your digestive tract, it would not stretch across a large tract of land, but only 25-28 feet — but that's still pretty long! (You probably don't need to read a tract on human anatomy to realize this would be an unhealthy experiment.)
