答案：B

翻譯：----她前幾天在市里讓別人修理的舊鐘重新運(yùn)轉(zhuǎn)良好（即：又好用）了.
----幸虧那個(gè)修鐘匠,它又重新好用了.

解釋：
1. 分析首句的結(jié)構(gòu)如下：
主句為：The old clock works well again.
而 she _____ in town the other day 為定語(yǔ)從句,修飾此句主語(yǔ)即先行詞the old clock.
2. 將先行詞the old clock代入此定語(yǔ)從句中,為：
(which/that) she had repaired in town the other day
= she had (which/that) repaired in town the other day
= she had (the old clock) repaired in town the other day
即關(guān)系代詞which/that代替先行詞the old clock,在從句中充當(dāng)使役動(dòng)詞had的賓語(yǔ),所以此定語(yǔ)從句的關(guān)系代詞which/that可以省略.
3. 固定結(jié)構(gòu)：使役動(dòng)詞have + 賓語(yǔ)sth(the old clock) + 賓語(yǔ)補(bǔ)足語(yǔ)repaired...
即該固定結(jié)構(gòu)have sth done的含義為“使某事被（別人）做”.
因?yàn)閠he old clock和repair之間為被動(dòng),所以賓語(yǔ)補(bǔ)足語(yǔ)使用repair的過去分詞repaired.
4. 從句的時(shí)間狀語(yǔ)the other day,意思是“幾天前/前幾天”,要求從句必須使用一般過去時(shí),所以正確答案為：had repaired,即答案B為正解.
而其他選項(xiàng)中,A錯(cuò)在it重復(fù)多余,CD錯(cuò)在時(shí)態(tài)有誤.
