OooO is a very common rhythm in questions beginning with "W" words (when where what,why,where and how).
在以W开头的问句中，句子发音的重音经常是在一头一尾
Example:
What do you think?
Why did you go?
Give it a shot试试:
When did she go?
Where does he work?
What did he say?
2. Auxiliaries are stressed in negative contractions and at the end of sentences.
辅词在否定的缩略语和句子结尾处强调。
（由于全文只能插入一个音频，此处有失望的表情，给大家加粗了）
Yes I do.
I don't know.
He won't say.
Yes I will.
当然了，如果想强调是人的话
Yes I will
课外知识补充:英语里面can和can't 发音如何区别?
很多时候t是根本听不出来的，很多时候要看语境来分别。其实我们还有另外一个方法。
can后面的动词重读,而can't的can重读.
如I can go
如果can是重读的,那么很有可能他读的是can't
如果go重读,那么毫无疑问表示的是肯定意思了.
Happy New Year~
