关于名词set
"A set of boxes is arrived." 和 "A set of boxes are arrived" 哪个对?
"Two set of boxes are arrived." 和 "Two sets of boxes are arrived" 哪个对?
答
应该是"A set of boxes is arrived." 和"Two sets of boxes are arrived".这类用量词表示数量的表示方法有很多,特别是不可数名词,比如一杯水（a cup of water)..这类表示方法只要记着看准量词是单数还是复数,胃语动词就跟着它单复变形（不用去管你写的那个名词是单数还是复数 ）.
比如,桌上有一杯咖啡（There is a cup of coffee.)
桌上有两杯咖啡（there are two cups of coffee)
