has taught 【详解】原句中“教”是关键词，表示“教”的动词是teach，“since + 时间点”是现在完成时的标志；主语She是第三人称单数，助动词用has，teach的过去分词是taught。 32． have drawn/painted 【详解】原句中“已经画了”是关键词，表示“已经画了”的词语是have drawn/have painted。draw/paint意为“画”，句子中“since I joined the painting club last year”是现在完成时的标志，现在完成时的结构为“have/has+动词的过去分词”，主语I为第一人称，助动词用have，draw的过去分词为drawn，paint的过去分词是painted。 33． dreamed of

ill是固定短语，意为“生病、病倒”，属于系表结构；since引导时间状语从句时，从句需用一般过去时，因此fall要变为过去式fell。故填fell；ill。 41． has been famous 【详解】原句中“闻名”为关键词，表示“以……而闻名”的短语为be famous for，句末的since Tang Dynasty是现在完成时的标志，现在完成时结构为have/has +
