least
1.at least有时作“至少”解。例如：He is at least fifty. （他至少有五十岁。）有时作“不论怎样”解。例如：He will at least die happily. （他不论怎样将死得快乐。）at the least=at least，但不很普通。
2.least有时作“即使最小”或“即使最少”解。例如：He wishes to know the least detail of your life. 和We are ready to advise everybody who is (in) the least interested in such matters.
3.not in the least是状语短语，作“一点也不”解。例如：He is not in the least interested in this subject. 有时在least后面加上degree，但不很普通。注意这种表达方式跟not a little大不相同，not a little作“很”解。
not in the least是状语短语，有时把in省去，但不很普通。not the least里的least用作形容词。有时作“一点也没有”解。例如：This subject has not the least interest for him. 有时作“最大的”解。例如：Not the least of the difficulties is that of obtaining enough water. （最大的困难便是得到足够的水。）在第一解里往往把not和the分开。例如：He does not take the least interest in this subject.
4.Least of all do I want to offend him里的Least of all作“最不”解，注意I前面有do。
5.注意B is the least more interesting than A (of the three, B, C, and D) 等句子里用least more。C is the least less interesting than D (of the three, A, B, and C) 等句子里用least less。参见more 7和most 9
