“我要和美國(guó)人講得一模一樣！”“我要和英國(guó)人講得一模一樣！”我們?cè)S多人都把語(yǔ)音的目標(biāo)定得非常之高。需要嗎？不需要。對(duì)于大多數(shù)人來(lái)說(shuō)，學(xué)英語(yǔ)是為了交流。交流是書(shū)面的交流和口頭的交流。我們只要達(dá)到這個(gè)交流的目的就行了。所以，我們訂立的英語(yǔ)語(yǔ)音的目標(biāo)應(yīng)該是：跟美國(guó)人交流，英國(guó)人交流的時(shí)候，他能夠聽(tīng)懂你的話(understandable)，他覺(jué)得可以就行了。如果再能讓人家很舒服地聽(tīng)懂(comfortably understandable)，那就更好了。

為了達(dá)到這個(gè)目標(biāo)，我們應(yīng)該朝著哪個(gè)方向努力呢？我們首要需要解決的發(fā)音問(wèn)題是什么呢？

What are the priorities for Chinese learners?

什么是中國(guó)的英語(yǔ)學(xué)習(xí)者首要解決的發(fā)音問(wèn)題？

What are the priorities for Chinese learners? Iu2019m going to spend most of the time on the last two topics. For the Chinese learners, remember, the tips, the tips are coming. What are the priorities for Chinese learners?再把這句話說(shuō)一遍中文是什么？對(duì)中國(guó)學(xué)英語(yǔ)的人來(lái)說(shuō)，最首要要解決的問(wèn)題是什么？All right? This is very important, because in English pronunciation, you have a lot of aspects. 英文里頭語(yǔ)音當(dāng)中項(xiàng)目也挺多的，for instance, sounds, consonants, vowels, 就是語(yǔ)音有單音，有元音，有輔音，and stresses, intonation, linkage連讀, loss of plosion, incomplete plosion, 失去爆破，等等，intonation, and rhythm, a lot of things. But what are the most important things for us Chinese students to solve? All right?Number 1. Weak forms.可能大家沒(méi)想到吧，怎么把弱讀放在第一個(gè)？Yes. Yes. I want to stress this. I want to emphasize. 我今天就要強(qiáng)調(diào)這個(gè),weak forms. Because this is very important. Ok, letu2019s go on.Word stress. Stress,重音, Word stress,單詞重音. Next one must besentence stress(語(yǔ)句重音). And the next one,rhythm. This is a new word. Actually you are very good at rhythm. Young people, nowadays, are very good at rhythm. 現(xiàn)在的年輕人，這個(gè)rhythm 特別好。節(jié)奏特別好。Because of disco, disco, dancing. Rhythm就是節(jié)奏。Learn this word after me. 學(xué)這個(gè)字。 Read after me: Rhythm…rhythm…rhythm. Very good. Ok? Next one.Intonation. Ok? Intonation. I think these are priorities for Chinese students. If you want to learn English pronunciation well, you must put these things first on the top of your list. Is that ok? All right.

Now you probably will ask me a question. What about the sounds, vowels and consonants?你的意思就是說(shuō)元音和輔音就不重要了？No. I didnu2019t mean that.我沒(méi)有說(shuō)它們不重要。我是說(shuō)它們的重要程度對(duì)中國(guó)學(xué)生來(lái)說(shuō)沒(méi)有這幾個(gè)更重要。Single sounds are important. 這個(gè)……單音也重要。單音重要是在什么情況下？在它不影響你理解意思的情況下，單音可以稍稍馬虎一點(diǎn)。For instance, pleasure. This sound appears in just a few words in English. 英文里頭有這個(gè)音的詞不是特別多。所以它不太容易引起誤解。如果你發(fā)得不是特別好，你說(shuō)Itu2019s a pleasure to me. People understand you. All right? People understand you. It does not affect understandability.它不影響人的理解，就不太要緊。But listen, I give you some examples. He is sick.他生病了。Right? If you say [θik], [θ], what does [θik] mean? Meaning he is stupid腦子笨. [θ] and [ s ]在這種情況下單音就一定要發(fā)準(zhǔn)，because they affect understandability, 影響理解了。Is that right? He is sick and he is thick. Now give you another example. Listen. Somebody said to me, “I have a lot of keys.”你有好多鑰匙啊？No, no, I have a lot of keys. 哦，你有好多大大小小的鑰匙��？Oh, no, no, I have a lot of keys. They call me Mommy. 哦，你有好多鑰匙，他們叫你…Oh, no…no, not keys, oh, you mean kids. 哦，你有好多小孩，他們都叫你媽媽。I have a lot of keys. You should have said…How to say it? Kids. Kids. Kids. Well, this is important. 單音到這個(gè)地方就重要了，它影響你的理解了就重要了。Donu2019t say I have a lot of keys. 在中國(guó)也沒(méi)有這種情況，I have a lot of kids. So these things are important. Why…why are they so important? I finished this. Ok. Please move on. Number 5.

此外，屠蓓教授就弱讀問(wèn)題進(jìn)行了補(bǔ)充說(shuō)明。

weak forms是我們中國(guó)學(xué)生比較，最弱的一條。

Because we know how to read the strong forms, for instance, from, Iu2019m from Beijing. No, no. I am from Beijing. 要弱讀。弱讀的里頭,please look at me. 主要是〔Y〕這個(gè)音。Please remember this 〔Y〕. If you remember this lecture, you remember this 〔Y〕. All right? Because this is very very important. You know, all the weak forms, almost all the weak forms, you can use this 〔Y〕instead of the other forms or tools. All right? Yes. Where do you study? Ok. Letu2019s read them, use 〔Y〕. 這個(gè)of, 讀作〔Yv〕, 讀作a cup of tea. A glass of water. A block of flats. The book that I want. I want to emphasize this. I hear a lot of people say the book that I want. Thatu2019s wrong. But you can say I want that book. 這個(gè)that 是指示代詞。But, 連詞的時(shí)候只能讀[],Ok? Bread and butter. All right. I want to talk about this bread and butter. All right. And, this word can be read in several ways. 一個(gè)是〔?d〕，一個(gè)是讀作〔Ynd〕.All right? 今天我們練的就是〔Yn〕。Now please listen to me. Bread and butter. 現(xiàn)在我們這樣讀，bread, butter，當(dāng)眾加一個(gè)〔Yn〕。Ok? One. Two. Very good. Beautiful English. Say it again. Bread and butter. Bread and bread. 省得你又說(shuō)bread 〔?nd〕butter. 聽(tīng)了又費(fèi)勁，又不好聽(tīng)。Letu2019s do it again. Ladies 〔Yn〕 gentlemen. Ladies 〔Yn〕 gentlemen. Donu2019t say Ladies 〔?nd〕gentlemen. Letu2019s say it again. Ladies 〔Yn〕 gentlemen. Very good. Next time, if you give a lecture, you say Ladies 〔Yn〕 gentlemen. 一下子就把人鎮(zhèn)住了。Oh. Yes. 英文太地道了。Letu2019s do it again. Bread 〔Yn〕 butter. Ladies 〔Yn〕 gentlemen. Itu2019s very good. Do you agree with me. This, this weak forms are very important. Yes. Yes. Very important. Please practice.

講座最后，屠蓓教授指出：The earlier, the better, but itu2019s never too late to learn.越早學(xué)英語(yǔ), 你的發(fā)音會(huì)越好，但是任何時(shí)候開(kāi)始學(xué)英語(yǔ)都不晚。

Practice makes perfect. Pronunciation is a skill, an ability. 發(fā)音, 練發(fā)音是什么? 它是一種技巧,是一種能力.Itu2019s just like practice piano, practice ballet dance. The more effort, the more time you put in, the better. I think if you work hard, you will make it.
