1。need , want。 require, be worth 等用ving 主動式 表被動意義。The film is worth seeing 。The blackboard needs cleaning。2。 wash, write , sell等詞 后接well表示布料好洗,筆書寫流暢,東西暢銷等時用主動形式表達被動意義。The pen writes well。the cloth washes well。The goods sells well。3。 不定式做定語時, 如果句子的主語就是該不定式的邏輯主語, 一般用主動表被動;I have something to do 。He has an importnat meeting to attend。但如果不是邏輯主語就要用被動式;Do you have anything to be taken there?。
