第一題 C
第二題 A
第一個(gè) which(that)
第二個(gè) the one [which (that)]
因?yàn)榈诙淙北碚Z(yǔ),所以添一個(gè)the one.由于關(guān)系代詞which 或者that 在定語(yǔ)從句作介詞in 的賓語(yǔ),可以省略若將兩句轉(zhuǎn)換為陳述句分別是什么？

1. This is the company that you worked in three years ago

2. This company is the one( that ) you worked in three years ago

這樣改過(guò)來(lái)你可以看得更清楚
