首先說(shuō)一下,這個(gè)句子時(shí)態(tài)有問(wèn)題.I've found應(yīng)為過(guò)去時(shí)I found,同時(shí)后面的賓語(yǔ)從句也要用過(guò)去時(shí),應(yīng)改為When unpacking my luggage,I found that I still kept your music CD that I borrowed from you five days ago.
when unpacking my luggage,這部分為時(shí)間狀語(yǔ),相當(dāng)于When （I was) unpacking my luggage,I found為這個(gè)句子的主語(yǔ)和謂語(yǔ)動(dòng)詞,后面的that引導(dǎo)的句子是一個(gè)賓語(yǔ)從句.賓語(yǔ)從句中cd后的that引導(dǎo)的句子為定語(yǔ)從句,修飾cd.
這句話的主干就是“I（主語(yǔ)）+ found(謂語(yǔ)動(dòng)詞）+that...(賓語(yǔ)從句）”
本句意為“當(dāng)我打開(kāi)行李時(shí),發(fā)現(xiàn)我仍然帶著五天前從你那兒借來(lái)的音樂(lè)CD”.
