Have you anything_(take) to your wife there?2) Have you any clothes _(wash), sir?” asked the maid.3) I cannot go out now as I have a lot of clothes_(wash)to be taken to be washedto wash 注意：若句子的主语并非不定式的逻辑主语时，不定式则必须用被动式。3. 在下列情况中用不定式的主动形式表示被动意思。2) 在“主语+表语（形容词）to do” 中， 主语也是不定式的逻辑宾语,即不定式动词和主语之间是动宾关系。This question is easy to answer. （分析：answer (动)-this question （宾） 注意：如果动词为不及物动词，则要注意介词的搭配。John is difficult to deal with. （分析：_(动)-_(宾)） 如：这扶手椅坐起来很舒服。这题目很难算出来。deal withJohnThe armchair is comfortable to sit inThe question is difficult to work out4.
