I cannot to have a holiday abroad own salary. [ ] A．spareB．help C．spendD．afford

afford的意思是“买得起或负担得起”，后面接不定式、名词或代词，常与can, could, be able to连用，多出现在疑问句或否定句中，如：We cannot afford to pay such a high price. Can you afford the expense?（你花得起这笔钱吗？）can afford to do 还可表示“做得到，忍得住”。afford sth.可表示“经得起（发生某事）”，如He can't afford such setback.（他经不起挫折。）

当我们表示“花得起钱做某事”时用afford to do sth.,例如：can't afford a holiday/the time（抽不出时间）等。I cannot afford to go out to eat every day.表示“我没钱，不能天天在外吃饭”。易混淆词“offer”表示“主动提出做某事”，如He offered me 100 yuan for the bike.（他出100元钱买车。）offer (to do) sth.只表示“愿做某事或愿给某物”，并不牵涉动作的结果。
