你是说中文还是英文?如果是中文,形成短句的定语、状语、补语都可以算是修饰短语。如果是英文,a large deal of、a plenty of和a good supply of 在多数情况下修饰不可数名词,如:a plenty of water, a geat deal of time,不过它们也可以修饰可数名词,如a plenty of men。 a quantity of在多数情况下修饰可数名词,如a quantity of boxes, 不过也可修饰不可数名词,如a quantity of milk。 quantities of与上述的一样 。一、只能修饰可数名词的词语有: many, many a(n), a good / great many, a (great / large) number of, scores of, dozens of等。例如: Scores of people went there in the first few days after its opening. 开业的头几天,很多人去了那儿。二、只能修饰不可数名词的词语有: much, a great deal of, a great / large amount of等。例如: Is there much water in the bucket? 桶里有很多水吗? 三、既能修饰可数名词又能修饰不可数名词的词语有: a lot of, lots of, plenty of (以上三个词语后谓语动词的数依of 后的名词的单复数而定),a great / large quantity of (其后谓语用单数),quantities of (其后谓语用复数)。例如: There is still lots of snow in the garden. 花园里还有许多雪。
