Question

Would like to go to Paris with us next year I'd like to but

Answer 1

that引导从句这里是修饰空格里的动词, 也就是修饰explain了什么.

如果换成C,B,就成了反对什么,即,我妈妈反对我太年轻.

可以这么用,

1, I am not against your trip to Paris.

2, I do not oppose your trip to Paris.

3, I do not object to your trip to Paris.

be against 和 oppose意思一致,表示言行上都反对,会有行动.

object to表示的反对通常是口头上的,类似不赞成.
