(=Is this the book which was recommended by the teacher?)这是老师推荐的那本书吗？3.不定式作定语(1)不定式作定语时的具体功能：表示将要发生的动作、表示一种同位关系(

12、逻辑上的主谓关系，不定式应用主动形式；如果不定式与所修饰的名词之间是逻辑上的动宾关系，不定式应用被动形式。The medical team to be sent to the flood-stricken areas will start off next month.派往洪灾地区的医疗队下个月将出发。there be句型中，作主语的名词后常接不定式作后置定语。There is nothing to worry about.没什么可担心的。辨析比较：过分、现分以及不定式作定语的区别语法形式语态及时间意义过去分词(短语)作定语done表示被动、动作已完成The problem discussed
