红色字母的读音发生了什么变化呢？
Let’s learn
当两个音相邻时，其中一个音常常受另一个邻音的影响而变成与其邻音相同，或相似，或变成第三个音，这种变音现象叫作音的同化。例如：
Nice to meet you. /mi t ju/→ /mi t u/
What would you like to drink, tea or coffee /w d ju/ → /w d u/
What did you do last night /d d ju/ → /d d u/
音的同化（Assimilation）
1. Can I get you something, Mary
2. Thanks, John! Could you give me some cold yogurt, please
3. Here, I got you one. It's really good yogurt.
4. Yuk! What did you do This is very bad yogurt!
5. Oh, did you find your yogurt not yummy
6. I bet you added some salt, didn't you
7. Ha ha, yes! I tricked you!
8. Just you wait! I'll get you next time!
