5．定语
定式与被修饰的名词往往构成逻辑上的关系。如名词 为不定式的逻辑主语，构成主谓关系； 若名词为逻辑宾语， 则构成动宾关系； He is not the first employee to arrive at the office this morning. There will not be enough space to stand in on the earth I have some books for you to read. 2、作定语的不定式与所修饰的名词之间是动宾关系， 不定 式动词又是不及物动词时，应在该动词上加上一个介词，如; He has a nice pen to write with. He is looking for a room to live in. He is said the best way to travel by is on foot.
