知识要领：
句子重音
在英语句子中，实词（如名词、动词、形容词、副词等）承载重要信息，一般需要重读；而充当语法功能的词（如冠词、连词、介词、助动词等）一般弱读。但这条读音规律并非一成不变，句子中的重音可以随着说话者要表达的意思的不同而变化。
Practice
Try to read the sentence. Notice the stress and meaning.
I didn't say he stole the money. (强调“不是我说的”)
I didn't say he stole the money. (强调“不是他偷的”)
I didn't say he stole the money. (强调“不是偷，可能是借的”)
