Percentages (= numbers of per cent) are written in words as twenty-five per cent and in figures as 25%.百分比用文字表示为 twenty-five per cent，用数字表示为 25%。
If a percentage is used with an uncountable or a singular noun the verb is generally singular.百分比与不可数名词或单数名词连用时，动词一般为单数：◆90% of the land is cultivated. * 90% 的土地为可耕地。
If the noun is singular but represents a group of people, the verb is singular in NAmE but in BrE it may be singular or plural.如果是单数集合名词，美式英语动词用单数，英式英语用单、复数均可：◆Eighty per cent of the work force is/are against the strike.百分之八十的劳动力都反对这次罢工。
If the noun is plural, the verb is plural.如果名词为复数，动词用复数：◆65% of children play computer games. * 65% 的孩子玩电脑游戏。
