I prefer ________his new ideaA.try outB.to try outC.trying out

B解析此题考查prefer的基本用法。Prefer表示更喜欢其常用的句型结构有：1.prefer A to B (AB皆为名词) 2.prefer doing A to doing B=would rather do A than do B=like doing A better than doing B. 3.prefer to do A(没有比较，只做一件事的就用这个）=would rather do A 4. prefer to doing A rather than doing B 5.注意事项： prefer 有时态变化，过去式为preferred，三单直接加s. would rather...than...无时态变化故选B。
