I need a knife to cut the watermelon with
When I handed the report to John,he said that George was the person {to send it to}
1这两句不定式做什么成分
2为什么要加with和to
3再例句
为什么是做定语呢。I need a knife不是完整的主谓宾了吗。而且第二句的the person是表语。为什么不定式也是表语

1.不定式在句中做定语,不定式作名词/代词的定语时一般位于修饰词之后;
2.如果不定式与这个修饰的名词/代词构成动宾关系,不定式中的动词应是及物动词,若不是及物动词,应加上适当的介词,你举的两个例子正好都是不及物动词,所以需要加上适当的介词；
3.(1)There are some chairs in the park for people to sit and take a rest on
(2)The old man needs a person to talk with

I need a knife to cut the watermelon with We need a knife to cut the cake I want to find a knife to cut the bread with now.这里的不定式是不是选择题Would you please pass me the knife(to cut the watermelon Pass me a knife to cut the bread with为什么要用with The girl wants to ___[cut] the cake with a knife.正确形式填空! The knife __he uesd to cut the bread is very sharp.A.with wh ( )I cut the bread ___ a knife A.for B.in C.on D.with i can cut the cake with a knife.(改为同义句） I will cut the cake with the knife.用knife作主语改成被动. Pass me a knife to cut the bread with.这里的后置定语为什么是用to do形式而不是 He gave me a knife to cut the bread with.这里的后置定语为什么要用to do形式
