Ban goc (Tiếng Anh)

** Transcriber's Notes ** Underscores mark italics; words enclosed in +pluses+ represent boldface; Vowels followed by a colon represent a long vowel (printed with a macron in the original text). To represent the sentence diagrams in ASCII, the following conventions are used: - The heavy horizontal line (for the main clause) is formed with equals   signs (==). - Other solid vertical lines are formed with minus signs (—). - Diagonal lines are formed with backslashes (\). -
