—Why not__________by boat for a change?
A.to try going B.try going C.try to go D.try and go
解析:本题考查接动名词或不定式作宾语的短语和词汇。Why not do sth.？是固定用法，接不带to的不定式；try to do 表示“试图做某事”；try doing sth.表示“尝试着做某事”，常指尝试不一样的方法或方式。
答案：B
2..—Did you play cards again last weekend?
—Rather than__________time playing cards,I devoted every effort to__________the report.
A.waste；writing
B.wasted；writing
C.to waste；write

解析:本题考查动名词的用法及固定句型。rather than后通常接不带to的不定式，devote...to...中的to为介词，后须接动名词。
