English Skills with Readings 8th Edition by John Langan

Exercise 68

Two of the following paragraphs provide sufficient details to support their topic sentences convincingly. Write AD, for adequate development, beside those paragraphs. There are also three paragraphs that, for the most part, use vague, general, or wordy sentences as a substitute for concrete details. Write U, for underdeveloped, beside those paragraphs.
Qualities in a Friend
There are several qualities I look for in a friend. A friend should give support and security. A friend should also be fun to be around. Friends can have faults, like anyone else, and sometimes it is hard to overlook them. But a friend can't be dropped because he or she has faults. A friend should stick to you, even in bad times. There is a saying that "a friend in need is a friend indeed." I believe this means that there are good friends and fair-weather friends. The second type is not a true friend. He or she is the kind of person who runs when there's trouble. Friends don't always last a lifetime. Someone you believed to be your best friend may lose contact with you if you move to a different area or go around with a different group of people. A friend should be generous and understanding. A friend does not have to be exactly like you. Sometimes friends are opposites, but they still like each other and get along. Since I am a very quiet person, I can't say that I have many friends. But these are the qualities I believe a friend should have.
