She has a son the same age of you.
這里的son后應該有個介詞with吧？
of 應該改為as吧？不是the same as搭配 嗎？
謝謝老師，學生期待您的解惑。

應用 the same as。又如：

She’s the same age as me.  她和我同歲。

Dutch is of the same origin as English.  荷蘭語與英語同出一源。

Her hair’s the same colour as her mother’s.  她頭發的顏色跟她母親的一樣。　　

This book is the same size as that.  這本書和那本書一樣大。　　

怎么沒有用介詞with 呢？老師，謝謝。

She has a son the same age of you.
這里的son后應該有個介詞with吧？

--------我給你回答這個問題：

1. 陳老師已把of you改為as you。

2.你想在son后加with，表示“帶有”之意，是嗎？其實，英語不這樣表達。請看：

He is of the same age as you. 也可說：

He is the same age as you.

She has a son who is of the same age as you.也可說：

She has a son who is the same age as you.

定語從句是系表結構時，有時可以省略who is，如：He is a man (who is) strong enough to lift the heavy box.  The man (who is) in the reading room is my teacher. 因此，你把上面的定語從句省去who is看看是個什么樣子：

She has a son (who is) the same age as you.

這樣還需要在son之后加with嗎？
