appointment
1.作“约会”解时appointment后面接for，如an appointment for tomorrow morning和an appointment for seven o'clock。说明了时刻也有接at的，如an appointment at seven o'clock。说“职位”appointment后面接of或as，那后面的名词前面往往没有a（或an），如an appointment of（或as）(a) treasurer。说“任命或委派职位”appointment后面接to，如his appointment to the professorship。
2.下面两句里的by appointment意思不同：
- The dean receives visitors by appointment（预约）.
- The dean fills his post by appointment（任命）.
3.appointment（约定）后面有时接不定式。例如：He forgot an appointment to address a meeting that evening.
