This is the same pen as I bought yesterday. 這和我買的那支鋼筆一樣。This is the same pen that I bought yesterday. 這就是我買的那支鋼筆。關(guān)系副詞的用法：關(guān)系副詞指代成分可否省略When時間狀語否Where地點狀語否why原因狀語否注意：why只能引導(dǎo)“限定”；若要用于“非限定”中，則須用for which引導(dǎo)。注意一：關(guān)系副詞 = 介詞 whichI still remember the day when I came here. (when = on which ) This is the house where I lived last year. (where = in which )There are many reasons why people like traveling.
