I'm going to paint it pink里面的be going to是不是看做一个助词来使用,和后面的实义动

I'm going to paint it pink里面的be going to是不是看做一个助词来使用,和后面的实义动 I'm going to paint it pink的be going to paint是不是在本句中做谓语? I'm going to paint it pink的宾语为什么是paint it pink I'm going to paint it pink的宾语不应该是it吗,可是为什么老师讲的是 paint it pin I'm going to paint it pink.这里的宾语it与宾补pink的关系是系动词与表语的关系（即主系表结 PAINT ITI`m going to paint it pink.paint it 是固定搭配吗 I'm going to paint it pink中谓语在哪? i'm going to paint it pink.请问为什么这里要用动词不定式 I'm going to paint it pink.这句话什么是主?什么是谓?什么是宾? I am going to paint it pink.句子成分分析 it在这个句子中作宾语, I am going to paint it pink.划一下句子成份. i am going to paint it red
