C.Put all your eggs in your basket D.Actions speak louder than words

Answer

D

【解析】

句意：——我保证我会努力工作为今年夏天的考试做准备。——真的吗？行动胜于雄辩。

考查谚语。 Every dog has its day人人都有得意日；Practice makes perfect熟能生巧；Put all your eggs in your basket孤注一掷；Actions speak louder than words事实胜于雄辩。结合语境，“我保证我会努力工作为今年夏天的考试做准备。——真的吗？” 可知，应该是"事实胜于雄辩"。故选D。
