英語(yǔ)中 can 和 can't 發(fā)音幾乎差不多，如何在口語(yǔ)中區(qū)分開(kāi)來(lái)？
英語(yǔ)中有很多連讀。
一、連讀
(1)“輔音+元音”型連讀
在同一個(gè)意群里，如果相鄰兩詞中的前一個(gè)詞是以輔音結(jié)尾，后一個(gè)詞是以元音開(kāi)頭，這就要將輔音與元音拼起來(lái)連讀。
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”型連讀
如果前一個(gè)詞是以-r或者-re結(jié)尾，后一個(gè)詞是以元音開(kāi)頭，這時(shí)的r或re不但要發(fā)/r/，而且還要與后面的元音拼起來(lái)連讀。
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，如果一個(gè)音節(jié)的前后都有字母r，即使后面的詞以元音開(kāi)頭，也不能連讀。
The black clouds are coming nearer and nearer.(nearer與and不可連讀)
(3)“輔音+半元音”型連讀
英語(yǔ)語(yǔ)音中的/j/和/w/是半元音，如果前一個(gè)詞是以輔音結(jié)尾，后一個(gè)詞是以半元音，特別是/j/開(kāi)頭，此時(shí)也要連讀。
Thank~you.
Nice to meet~you.
Did~you get there late~again?
Would~you like~a cup~of tea?
Could~you help me, please?
“音的同化”
—常把/d/+/j/讀成/dV/，did you聽(tīng)上成了/dIdVu/，would you成了/wudVu/，could you成了/kudVu/。
(4)“元音+元音”型連讀如果前一個(gè)詞以元音結(jié)尾，后一個(gè)詞以元音開(kāi)頭，這兩個(gè)音往往也要自然而不間斷地連讀到一起。
I~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.
(5)當(dāng)短語(yǔ)或從句之間按意群進(jìn)行停頓時(shí)，意群與意群之間即使有兩個(gè)相鄰的輔音與元音出現(xiàn)，也不可連讀。
Is~it a~hat or a cat?(hat與or之間不可以連讀)
There~is~a good book in my desk. (book與in之間不可以連讀)
Can you speak~English or French? (English與or之間不可以連讀)
Shall we meet at~eight or ten tomorrow morning? (meet與 at，eight與or之間不可以連讀)
She opened the door and walked~in. (door與and之間不可以連讀)
二、吞音
6個(gè)爆破音有3對(duì)/p/，/b/，/t/，/d/，/k/，/g/
失去爆破，又叫不完全爆破，就是在某些情況下，只須做出發(fā)音的準(zhǔn)備，但并不發(fā)音，稍稍停頓后就發(fā)后面的音。
(1)“爆破音+爆破音”型
6個(gè)爆破音【t、d、k、g、p、b】中的任意2個(gè)相臨時(shí)，前一個(gè)爆破音會(huì)失去爆破，即由相關(guān)的發(fā)音器官做好這個(gè)發(fā)音的姿勢(shì)，稍做停頓后即發(fā)后面的爆破音。
The girl in the re(d) coat was on a bla(ck) bike jus(t) now.The bi(g) bus from the fa(c) tory is full of people.
Wha(t) time does he get up every morning?
This is an ol(d) pi(c)ture of a bi(g) car.
The ol(d) do(c)tor has a ca(t), too.
We’re going to work on a farm nex(t) Tuesday.
What would you like, ho(t) tea or bla(ck) coffee?
It’s a very col(d) day, but it’s a goo(d) day.
You can put i(t) down in the bi(g) garden.
I bought a chea(p) book, but it’s a goo(d) book.
(2)“爆破音+摩擦音”型如果前面是爆破音，其后緊跟著某些摩擦音（如/f/，/s/，/W/，/T/等），那么前面那個(gè)爆破音僅有十分輕微的爆破，而后面那個(gè)摩擦音則要完全爆破。
Goo(d) morning, Mr. Bell.
Goo(d) morning, dear.
Uncle Li’s fa(c)tory is qui(te) near to the cinema.
I wen(t) there alone a(t) nine las(t) night.
-Do you know his bi(ke) number? -Sorry, I don’(t) know.
The forty-firs(t) lesson is qui(te) difficult.
Goo(d) luck, Lin Tao.
