49．D
【详解】句意：“一叶知秋”这个成语告诉我们，一片落叶预示着秋天的来临。
考查宾语从句和成语。why leaves fall in autumn为什么树叶会在秋天落下；how important the leaves are in autumn秋天的树叶是多么的重要；which kind of leaf knows autumn is coming哪一种叶子知道秋天来了；that a falling leaf reveals the coming of autumn一片落叶预示着秋天的来临。分析题干可知，空格处是宾语从句，宾语从句要采用陈述语序，成语“一叶知秋”表示“从一片树叶的凋落，知道秋天的到来”。故选D。
50．C
【详解】句意：——Mike，你在中国的第一个端午节就要到了。我们一起庆祝好吗？——我很想去，但是你能告诉我你们通常是怎么庆祝这个节日的吗？
考查宾语从句。tell后缺少直接宾语，用宾语从句，宾语从句用陈述语序，排除选项A和D；根据“Mike, your first Dragon Boat Festival in China is coming. Shall we celebrate it together ”可知第一次来，想知道通常如何庆祝这个节日，用how引导宾语从句。故选C。
