afford既然是及物动词为什么要加TO

Question

如题所述

Answer 1

afford是及物动词，后面可用动词不定式作宾语。你看到的to不是介词，而是动词不定式上的to。如: They can't afford to equip their army.追答

这个 to equip 作及物动词afford 的宾语。

要是名词作宾语就不需要to了。如: Only those with deep pockets, however, could afford the $25,000 cost of each device.

Answer 2

当afford做非谓语动词时，需要用不定式，所以加to
