五大音变之一：连音
五大音变之二：增音
native speakers喜欢把 there is说成there ris
there are 说成 there rare
这个其实也是连读的一种，是末尾辅音r的一个延续拼读
do it说成 do wit，
这也是do末尾w口型的一个延长。
蓝教授把这个规律总结成“增音”
五大音变之三：减音
看电影，有时会遇到I didn't... 和 give him的句型，
前者说成了di n't; 后者说成了givim
蓝教授把这个规律说成了“减音”
五大音变之四：变音
spend变成了sbend
stop 变成了 sdop
sky 变成了 sgy
strong 变成了 sdrong
这些现象，蓝教授称作为“变音”
