单词Approve和短语approve of形式上看仅仅是多了介词of, 但两者所表达的意思明显不同：
- I cannot approve the reimbursement because you haven’t given me the receipts for your expenditure.
- I cannot approve your application to study law because you do not have the relevant qualifications.
2, Approve of指“同意，满意”，并没有“批准”的意思
- I don’t approve of smoking in restaurants because it is so upsetting usually for non-smokers.’
- Why don’t you approve of my friends? They are all good upright people.’
