很顯然which是多余的,which一般用在定語從句中,引導(dǎo)定語從句,但這句話沒有先行詞,也不是定語從句,就不需要which.
正確的句子應(yīng)該是：
They soon became popular with their beautiful voice.
他們不久就憑借自己優(yōu)美的嗓音而受到歡迎.那改成the voice with which they soon became popular呢，是不是要加逗號(hào)呢你如果這么改的話和原來的意思就不一樣了，原來的句子the voice 作介詞賓語，你要這么改，只有主語，沒有謂語了，他們因之而出名的嗓音，后面就沒有內(nèi)容了，怎么樣??？你看看這樣可以嗎？The voice with which they soon became popular is very beautiful. 他們借之而出名的嗓音非常好聽。
