弱读三大原则
一,弱读成/ə/音：这是最重要的原则，大部分的元音弱读都可以弱读成/ə/音。
二,省略：基本上所有h开头的单词在句子中弱读时都可以把h发音省略;省略元音/f/
三，长元音变短元音：如/i:/ ->/i/，/u:/ -> /u/
说完了理论，最重要的就是实际使用了。下面是一些常用单词在句子中的弱读形式。
A. me we she
这类原来是长元音结尾的，弱读都变成短元音
me /miː/ ->/mi/，we /wiː/ ->/wi/，she/ʃiː/ ->/ʃi/
B.冠词
1.a
这个单词弱读时，基本是感觉嘴间一阵风一带而过的感觉。举例：a /ə/ Have a nice day
2.an
这个单词，一般老师教的是重读形式，为/æn/。但它在句子中的实际发音是/ən/。举例：an apple a day ; He is an interesting person.
3.the
这个单词在辅音前，发音为/ðə/ ，举例：the letter; 在元音前，发音为/ði/，举例：in the end
C.代词
1.he his him:
这些单词在句首一般保留h发音，但是在句中一般省略h音，将其弱读成/i/ /iz/ /im/。
He /hi/ likes the film. His /hiz/ face is red. Did he /i/ come? I like him /im/.
2.her: 在辅音前，发音为/ə/ Let her go; 在元音前，发音为/ər/ Send her away.
3.us:/ʌs/ 弱读成 /əs/，举例：please help us.
4.your: 重读为/jɔː/；在辅音前，弱读为/jə/，举例：do your best; 在元音前，弱读为/jər/ ，举例：on your own
5.them:重读为/ðem/，弱读为/ðəm/，举例：I spoke to them.
D.助动词，系动词
1.be:/bi/ Be careful;
2.am:/əm/;
3.are:辅音前，弱读为/ə/ You are late;元音前，弱读为/ər/ we are eager to learn；
4.were:辅音前，弱读为/wə/;元音前，弱读为/wər/；
5.is:/z/ He is here.
6.was:/wəz/
7.do:辅音前，弱读为/də/ where do they live; 元音前，弱读为/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:很多人一般只会说/mʌst/，语气很重，有种命令和强迫的感觉，但是/məst/就会弱很多。举例：we must /məs/ be careful. You must /məst/ eat it.
15.would:/wʊd/ ->/wəd/ Would you help me?
16.been:/bi:n/ -> /bin/
17.and:是使用最多的，也是最容易出错的。大多时候，and都不发/ænd/，而是变成：/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

22.from:/frɒm/ -> /frəm/ I'm from China.
23.than:/ðæn/ ->/ðən/ better than before
24.of:/ɒv/ ->/əv/ a cup of coffee
25.to: 辅音前，弱读为/tə/ I go to bed at ten; 元音前，弱读为/tu/ He has gone to America.
26.that:/ðæt/ ->/ðət/ They said that they would come.
