English uses question tags - you make you voice go up at the end of the sentence you know? Chinese uses little words like 呢 to indicate a question. Or you can just use correct Chinese grammar for questions - "He said what" or "Who said that" or "This is how much". Tones are used for emphasis (emphasising the tone emphasises the word), but not for questions.
