Let’s watch and learn.
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；
重读（stress）
Please pass me the book.（强调把“书”递给我，而不是把别的东西给我）
Please pass the book to me.（强调把书递给“我”，而不是给其他人）
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变化而变化。
A: I think she will win.
B: She won’t.（预测她“不会”赢）
A: She will.（坚信她一定“会”赢）
一般情况下，me、will 等功能词在句中弱读，但在上述情境中这两个词需要重读。

1. I’m starting a test on animals and plants. 我要开始一场关于动植物的测试。
在此句中，on 是介词 ，意为 “关于；有关” ，用来表明 test（测试）的内容主题是 animals and plants 。
例如：She wrote a book on history. 她写了一本关于历史的书。
【辨析】about与on
on 强调专业性、学术性或严肃性，内容通常是系统的、深入的，涉及理论、研究或专门领域。
about 侧重日常性、通俗性或泛泛而谈，内容更偏向非正式的内容。
例如：She told me a story about her pet dog.
她给我讲了一个关于她宠物狗的故事。
