由於最近在進修托福文法書，出現了一些疑惑，因此想請教板友們，謝謝大家！

求板上英文大神救援！！謝謝大家！

第4題的答案有抄對嗎?

是的，照書上的全抄

我感覺第4題應為a。選項 d的寫法看得懂，但這語意我會改成 one of my sister's boyfriends，且 boyfriends 前沒加ex- 也怪怪的...

3,4老掉牙問題，雙重所有格。使用情境是determiner(限定詞)與possessive(所有格)共同修飾同一個名詞時，句型是「限定詞+N+of+所有格」。4d只能表示姊姊的一位男友，她有幾個男友是不確定的。

第四題答案應該是A，書本應該誤植。

vincent 的說法是文法真的這樣教，但 natural speaking 比較像是 one of my ...s. 我選a 是相較4其他3項較直覺表達。而且就一個男友哦。

1.a=>one like it in Athen, 1.b=>去掉a2.可能than當介系詞用，翻做「他是她的兒子，沒有年輕人比他來得親切」。文學作品較常見此用法，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是一樣的意思但我也說不出來為什麼不能選A就是了 XD

a space in between makes a big different. 此題這裡是男朋友，而非男的朋友。

Merriam Webster字典裡面，boyfriend的第一個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.
