求板上英文大神救援！！谢谢大家！

第4题的答案有抄对吗?

是的，照书上的全抄

我感觉第4题应为a。选项 d的写法看得懂，但这语意我会改成 one of my sister's boyfriends，且 boyfriends 前没加ex- 也怪怪的...

3,4老掉牙问题，双重所有格。使用情境是determiner(限定词)与possessive(所有格)共同修饰同一个名词时，句型是“限定词+N+of+所有格”。4d只能表示姊姊的一位男友，她有几个男友是不确定的。

第四题答案应该是A，书本应该误植。

vincent 的说法是文法真的这样教，但 natural speaking 比较像是 one of my ...s. 我选a 是相较4其他3项较直觉表达。而且就一个男友哦。

1.a=>one like it in Athen, 1.b=>去掉a2.可能than当介系词用，翻做“他是她的儿子，没有年轻人比他来得亲切”。文学作品较常见此用法，字典例句https://goo.gl/fH5rj3 , http://goo.gl/TrvgLs

boyfriend有男生朋友的意思啊…又不是只有男朋友的意思就跟I saw a friend of hers是一样的意思但我也说不出来为什么不能选A就是了 XD

a space in between makes a big different. 此题这里是男朋友，而非男的朋友。

Merriam Webster字典里面，boyfriend的第一个definition就是a male friend.

No. This isn't conventional way we define a "boyfriend." In your case, I'd rather call it a malefriend or a female friend instead of ambiguous term.For your information from wiki: There is a significant difference between girlfriend and齩oyfriend, and䓻irl friend and齩oy friend. In a strictly grammatical sense, agirlfriend or齩oyfriends an'individual of significance' with whom one sharesa relationship.And it is very easy to get to feel what a boyfriend or girlfriend is in context of a lot of youtube programs.
