你说的是连读吧
来看
连读的定义：
在同一意群中,前一词以辅音音素结尾,后一词以元音音素开头,在说话或朗读句子时,习惯上很自然地将这两个音素合拼在一起读出来,这种语音现象叫连读.
连读的类型：
(1)“辅音+元音”型连读
在同一个意群里,如果相邻两词中的前一个词是以辅音结尾,后一个词是以元音开头,这就要将辅音与元音拼起来连读.
例如：
I’m~an~English boy.
It~is~an~old book.
Let me have~a look~at~it.
Ms Black worked in~an~office last~yesterday.
I called~you half~an~hour~ago.
Put~it~on,please.
Not~at~all.
Please pick~it~up.
(2)“r/re+元音”型连读
如果前一个词是以-r或者-re结尾,后一个词是以元音开头,这时的r或re不但要发[r],而且还要与后面的元音拼起来连读.
例如：
They’re my father~and mother.
I looked for~it here~and there.
There~is a football under~it.
There~are some books on the desk.
Here~is a letter for you.
Here~are four~eggs.
But where~is my cup?
Where~are your brother~and sister?
但是,如果一个音节的前后都有字母r,即使后面的词以元音开头,也不能连读.
例如：
The black clouds are coming nearer and nearer.（nearer与and不可连读）
(3)“辅音+半元音”型连读
英语语音中的[j]和[w]是半元音,如果前一个词是以辅音结尾,后一个词是以半元音,特别是[j]开头,此时也要连读.
例如：
Thank~you.
Nice to meet~you.
Did~you get there late~again?
Would~you like~a cup~of tea?
Could~you help me,please?
此处出现了“音的同化” 现象,也就是发音者常把[d]+[j]读成[d],did you听上成了[didu],would you成了[wudu],could you成了[kudu].
(4)“元音+元音”型连读
如果前一个词以元音结尾,后一个词以元音开头,这两个音往往也要自然而不间断地连读到一起.
例如：
am Chinese.
He~is very friendly to me.
She wants to study~English.
How~and why did you come here?
She can’t carry~it.
It’ll take you three~hours to walk there.
The question is too~easy for him to answer.
