English Skills with Readings 8th Edition by John Langan

Exercise 4

Each item that follows lacks basic punctuation. There is no period to mark the end of one sentence and no capital letter to mark the start of the next. Read each item aloud (or in your head) so that you "hear" where each sentence begins and ends. Your voice will tend to drop and pause at the point of each sentence break. Draw a light slash mark (/) at every point where you hear a break. Then go back and read the item a second time. If you are now sure of each place where a split occurs, insert a period and change the first small letter after it to a capital. Minor pauses are often marked in English by commas; these are already inserted. Part of item 1 is done for you as an example.
One of the biggest regrets of my life is that I never told my father I loved him I resented the fact that he had never been able to say the words "I love you" to his children even during the long period of my father's illness, I remained silent and unforgiving then one morning he was dead, with my words left unspoken a guilt I shall never forget tore a hole in my heart I determined not to hold in my feelings with my daughters they know they are loved, because I both show and tell them this all people, no matter who they are, want to be told that they are loved.
