英语表示名词的所有关系一般有两种形式,一是名词+of语,多用于无生命名词的所属关系,如a map of China;另一种形式是由名词+’s构成,这种形式多用于有生命的名词所属关系,如Mary’sschoollbag。这两种形式结合在一起,构成了双重所有格。 There are generally two forms of all the relations of English expression of nouns. One is the noun+of language, which is mostly used for the affiliation of inanimate nouns, such as a map of China; the other form is composed of noun+’s. The affiliation of a living noun, such as Mary’s schoollbag. These two forms combine to form a double possession.
