of，them和did这三个词在口语发音中可不仅仅是按照音标来发音那么简单哦！美国人其实都是这样发音的。。。
1.of 尾音[t] + of [v] 时 a lot of = a lotta
例子：I have a lotta money
Let‘s get out of here。 = Let’s get outta here outta。
2。动词介词后面跟them时 t-h--e-m 变成‘em
例子I love them。 = I love‘em。
I like them。 = I like‘em I hate them。 = I hate’em。
many of them = many of‘em talk to them= talk to’em
shame on them= shame on‘em
3。特殊疑问句+did 时did变成 ‘d
例子Where did you go。 = Where‘d you go。
What did you say。 = What‘d you say。
How did it go。 = How‘d it go。
How did you do it。= How‘d you do it。
