弱讀三大原則
一,弱讀成/ə/音:這是最重要的原則,大部分的元音弱讀都可以弱讀成/ə/音。
二,省略:基本上所有h開頭的單詞在句子中弱讀時都可以把h發音省略省略元音/f/
三,長元音變短元音:如/i:/ ->/i/,/u:/ -> /u/
説完了理論,最重要的就是實際使用了。下面是一些常用單詞在句子中的弱讀形式。
A. me we she 
這類原來是長元音結尾的,弱讀都變成短元音
me /miː/ ->/mi/,we /wiː/ ->/wi/,she/ʃiː/ ->/ʃi/
B.冠詞
1、a
這個單詞弱讀時,基本是感覺嘴間一陣風一帶而過的感覺。舉例:a /ə/ Have a nice day
2、an
這個單詞,一般老師教的是重讀形式,為/æn/。但它在句子中的實際發音是/ən/。舉例:an apple a day He is an interesting person.
3、the
這個單詞在輔音前,發音為/ðə/ ,舉例:the letter 在元音前,發音為/ði/,舉例:in the end
C.代詞
1、he his him: 
這些單詞在句首一般保留h發音,但是在句中一般省略h音,將其弱讀成/i/ /iz/ /im/。
He /hi/ likes the film. His /hiz/ face is red. Did he /i/ come? I like him /im/. 
2、her: 在輔音前,發音為/ə/ Let her go 在元音前,發音為/ər/ Send her away.
3、us:/ʌs/ 弱讀成 /əs/,舉例:please help us.
4、your: 重讀為/jɔː/在輔音前,弱讀為/jə/,舉例:do your best 在元音前,弱讀為/jər/ ,舉例:on your own
5、them:重讀為/ðem/,弱讀為/ðəm/,舉例:I spoke to them.
D.助動詞,系動詞
1、be:/bi/ Be careful
2、am:/əm/
3、are:輔音前,弱讀為/ə/ You are late元音前,弱讀為/ər/ we are eager to learn
4、were:輔音前,弱讀為/wə/元音前,弱讀為/wər/
5、is:/z/ He is here.
6、was:/wəz/
7、do:輔音前,弱讀為/də/ where do they live 元音前,弱讀為/du/ How do you do
8、does:/dAz/ -> /dəz/
9、have: /həv/ I have met him before /əv/ The visitors have arrived.
10、has:/həz/She has comes/əz/ The place has changed.
11、had: /əd/ He said his son had gone aboard.
12、can:/kən/ Can you help me?
13、could:/kʊd/ ->/kəd/
14、must:很多人一般只會説/mʌst/,語氣很重,有種命令和強迫的感覺,但是/məst/就會弱很多。舉例:we must /məs/ be careful. You must /məst/ eat it.
d:/wʊd/ ->/wəd/ Would you help me?
16.、been:/bi:n/ -> /bin/
17、and:是使用最多的,也是最容易出錯的。大多時候,and都不發/ænd/,而是變成:/ən/ rain and snow/n/ bed and breakfast/ənd/ snow and ice
18、as:/æz/ -> /əz/, as soon as possible
19、at:/æt/ -> /ət/ She is at home.
20、but:/bət/ nothing but truth
:/fɔ:(r)/ ->/fə/ Thanks for coming.
:/frɒm/ -> /frəm/ I'm from China.
:/ðæn/ ->/ðən/ better than before
:/ɒv/ ->/əv/ a cup of coffee
: 輔音前,弱讀為/tə/ I go to bed at ten 元音前,弱讀為/tu/ He has gone to America.
:/ðæt/ ->/ðət/ They said that they would come.
:/sʌm/ -> /s(ə)m/ It will take some time.
