英語(yǔ)專(zhuān)八水平為您解答.
您第一個(gè)問(wèn)題：兩個(gè)詞組區(qū)別不大.
這涉及名詞屬格與of-詞組的用法,二者在意義與用法上有很多相通之處,都可表示所有關(guān)系,a brother of my mother等于my mother's brother,后面的a brother of my mother's等于one of my mother's brothers.
第二個(gè)問(wèn)題選A.
這里的獨(dú)立屬格在of-詞組中作介詞補(bǔ)足成分,這一題考察的是雙重屬格.
of-詞組和雙重屬格有時(shí)可交替使用,其意義有區(qū)別,給你一個(gè)簡(jiǎn)單的例子：
He is a friend of my father's.相當(dāng)于He is one of my friend's friends.
He is a friend of my father.相當(dāng)于 He is friendly to my father.
兩句的區(qū)別很明顯了吧.
