【正确答案】 C

【答案解析】解析：连词than前后的不定式短语to get rid of(解雇)与to employ(雇用)相互对应，最符合上下文的概念。A和D项选择是同义词，都是"解雇"意思，两者可以互换使用，不可能是正确答案。B项选择的apply应与介词for搭配使用，意思为"申请"。

【正确答案】 D

【答案解析】解析：本句话与上句话是对比关系，上面讲"内部招聘"的优点，而本句讲它的缺点："他们在职位上很难会有新的思想和见解"。两个句子意思正相反，应该用转折连词"however"，后面用逗号与句子隔开。

【正确答案】 B

【正确答案】 A

【答案解析】解析：本句话应该与前面的句子为对比关系，只能用连词while连接后面的句子，意思为：而招聘IT业职位和国外招聘最好的方法之一就是在互联网上登广告。其他的选择项用法有误。
