在写作英文论文时，如果一个句子是以“数目”开头，这个“数目”应以“全写”形式出现（If we start a sentence with a number we should write out the number），也就是说，阿拉伯数字一般不应直接放在一句话的开头，例如，“40 sets of 3D points distribution face model data selected randomly from a monolayer face sample library are taken as the face samples of feature points which will be located”是不正确的。这句话开头的数目40应“全写” 为Forty，也就是说“Forty sets of 3D points distribution face model data selected randomly from a monolayer face sample library are taken as the face samples of feature points which will be located”是正确的。
