区别在于用法上的不同。
1、a great deal of后面要接名词,不可单独使用,且a great deal of只能修饰不可数名词。
例句:
①No one is worth a great deal of sacrifice.
没有谁值得付出重大的牺牲。
②Running a kitchen involves a great deal of discipline and speed.
料理好厨房需要把一切都安排得规规矩矩,且要讲求速度。
2、a great deal可以不加名词,这个时候它就被用作副词了。
例句:
①Exercising the body does a great deal to improve one's health.
锻炼身体对增进健康大有益处。
②Your contribution means a great deal not only to this organization, but also to the whole world.
你们的贡献意义重大,不仅是对于这个协会,而且对于整个世界。
