Gr 4-7 The author of Love and Sex in Plain Language (Lippincott, 1977) has done a question-and-answer book based on an open-ended survey of 1000 boys and girls in fourth, fifth and sixth grades. His introduction to parents and teachers acknowledges that some of these questions may shock, but that if the children ask them, they should be given straightforward answers. He is gracious in his credit to Beth Winship, and indeed, her book Ask Beth; You Can't Ask Your Mother (Houghton, 1972) is more interesting and informative in answering complicated emotional problems. Johnson excels in clarifying common misconceptions about sex. His objectivity on controversial issues such as abortion and homosexuality is welcome. He uses no slang; some of his answers read a bit like an anatomy textbook. He discusses venereal disease, listing the phone number for the VD Hotline. Johnson presents open-minded cases on many other issues, such as creation and evolution. He tends to use slogans as shortcuts to moral viewpoints (hitting is always dangerous to love; you are of infinite value; you can't control what you feel but you must control how you act). He takes seriously some questions that seem to have been asked for their sniggering value, though a touch of impatience shows in his answer to ``How long does it take to get a girl hot?'': ``The answer is that it's the wrong question!'' The chapter on human reproduction is illustrated with diagrams and pencil drawings of the male and female reproduction systems and of a baby being born. This is no replacement for his fine earlier works but an interesting supplement. Anne Osborn, Riverside Public Library, Calif.
