Hello, I'm John Russell.
大家好，我是约翰·罗素。
Today let's explore one area of connection between grammar and pronunciation.
今天我们来探讨一下语法和发音之间的联系。
This area of connection involves auxiliary verbs, verbs such as can, could, should, would and so on.
这个联系涉及助动词，如can, could, should, would等动词。
These words modify or change the meaning of a main verb.
这些词修饰或改变了主要动词的意思。
Consider this statement: I can speak English. I can speak English.
想想这句话：我会说英语。我会说英语。
The main verb is speak. The auxiliary verb is can. It suggests ability.
主要动词是speak。助动词是can。表示能力。
Notice something about how I pronounce can: I can speak English. I can speak English.
注意一下can的发音：我会说英语。
I changed the vowel sound in "can" .
我改变了can中的元音发音。
Instead of can I said /ken/. I /ken/. I /ken/ speak English.
没有读/kan/，我读的是/ken/。我会说英语。
Americans often do this change in everyday speech.
美国人在日常讲话中经常这样做。
This is the so-called weak form.
这就是所谓的弱读形式。
Now consider this statement: I can't speak English. I can't speak English. I can't speak English.
现在想一下这个表达：我不会说英语。我不会说英语。我不会说英语。
Notice that in this sentence: I said the negative form of the auxiliary verb louder and in a high pitch.
注意在这个句子中：我读的助动词的否定形式更响亮，而且音调很高。
The vowel sound didn't change either.
元音的发音也没有改变。
Now compare the two: I can speak English. I can't speak English. I can speak English, I can't speak English. I can speak English, I can't speak English.
现在比较两个表达：我会说英语。我不会说英语。
This example teaches you a general idea about American English.
这个例子教你美式英语的一般概念。
Americans reduce or do not stress auxiliary verbs when they have a positive or affirmative meaning.
当助动词具有肯定或肯定的意思时，美国人会减少或不重读助动词。
Americans often stress auxiliary verbs in their negative forms.
美国人经常重读否定形式的助动词。
That is why the two statements sound different.
这就是为什么这两种表达听起来不同。
Listen again. I can speak English. I can't speak English. I can't speak English.
再听一遍。我会说英语。我不会说英语。我不会说英语。
The next time you listen to Americans speak, pay careful attention to how they pronounce auxiliary verbs.
下次你听美国人说话时，要注意他们助动词的发音。
With time and hard work, you too can pronounce these words much like Americans do.
经过时间和努力练习，你也可以像美国人一样发这些单词的音了。
That's all for today. Keep up the good work.
以上就是本期的全部内容，继续加油吧。
