49．My brother is so interested in languages that, he is now learning _____ third language besides Eng-lish and French.
A．不填 B．the C．a D．that

全面分析：我弟弟对语言很感兴趣, 他正在学习英语和法语之外的又一门语言。结合后文third language besides Eng-lish and French以及语境“英语和法语之外的又一门语言”可知此处为结构“不定冠词a / an + 序数词 + 名词”, 强调在已知数量上再累加一个, 翻译成“又一个”。故选C。

50．Believe it or not, everything comes with_____ price; there is no such_____ thing as free lunch.
A． a; a B．the; / C．/; / D．a; /

全面分析：每件东西都有一个价格；世界上没有像免费的午餐一样的东西。前文价格泛指任何一个价格，当such前面有no时，必须省去不定冠词a(an)，因为no such本身已经包括了不定冠词，相当于not such a(an)故不用冠词，故选D。
