托?？荚囌Z(yǔ)法指導(dǎo)：語(yǔ)法問(wèn)題之九

請(qǐng)教一語(yǔ)法題：
     The commutation of a criminal's sentence differs from a pardon ____________
     reduces the terms of punishment rather excuses the criminal completely.
     (A) in that
     (B) that it in
     (C) in that it
     (D) that in
     哪一個(gè)是正確的?為什么？
     Thanks
    我覺(jué)得是C
    首先BD是肯定不對(duì)的(看看后面的reduces就知道不能用介詞in接reduces)A同樣道理，若選A，則從句缺少主語(yǔ)。其實(shí)，若從意思上看，直接選C就行，也不用排除法了。
