失音归纳：
（1）辅音+辅音——同性相斥
I don’t-know what-to do.
I need-some-more money.
I’d like-to try on that-shirt.
What-time is our flight-tomorrow
（2）同类爆破+同类爆破
相同的两个爆破音相邻时，第一个爆破音省略，只读后面的一个爆破音。
She’s looking for a part-time job
I’ll take-care-of the problem.
<略音和连音同时出现>
（3）异类爆破+异类爆破
类似的辅音
如：[t] –[d]；[d]--[t]；[k]-- [g]；[p]--出现时，同样省前读后。
What do you think?
Sorry, I wasn’t listening.
The boss has always been very good to her.
We had a good time together.
You’d better get up a little earlier.
（4）略音 在以[t][d][k][g][p]和+以辅音开始的单词时，前面的辅音发音顿息，舌头达到发音部位“点到为止”，但不送气！在正常速度或快速的对话中，字尾有[t][d]时通常不会把[t][d]的发音清楚地念出来，而是快要念出来时，马上憋气顿息，因此字尾[d][t]的发音常常是听不到的。
Let me try it
Maybe he’d like to be alone now
I might be getting a big raise this month.
Not a chance
Is it going to rain tomorrow?
I hope not. I want to go to the beach.
