Hello. I'm John Russell.
大家好，我是约翰·罗素。
Today, we are going to continue exploring some of the most difficult vowel sounds for non native, speakers of English.
今天，我们将继续为非英语母语人士探索一些最难的发音。
Let's start a review of the /倒e/, /a/, /ao/ and /ou/ sounds.(注:此音标写法为便于编辑，规范写法见视频)
让我们开始复习/倒e/、/a/、/ao/和/ou/的发音。（注：此音标写法为便于编辑，规范写法见视频）
The reason you need to pay careful attention to these four sounds is because non-native speakers often mix them up.
你需要仔细注意这四个音，因为非母语人士经常混淆它们。
That's not always a bad thing.
这并不总是一件坏事。
For example, /a/ as in father and /ao/ as in laws sound very similar.
例如，作为father（父亲）的/a/音和laws的/ao/音非常类似。
In many parts of the United States, the two vowels are pronounced the same way.
在美国的许多地方，这两个音发音一致。
So don't worry too much about the difference between /a/ and /ao/.
所以不用太担心/a/和/ao/的区别。
But be careful about mixing up some of the other sounds.
但是要注意不要把其他的音混淆。
For example, the common name, Doug, has the /倒e/ vowel sound.
例如，常用的名字“Doug”里面有/倒e/的音。
But if you use the /ao/ vowel sound instead, the word becomes dog.
但是如果发成了/ao/的音，这个词变成了dog狗。
Let's practice.
让我们练习一下吧。
Pay special attention to the /倒e/, /a/, /ao/ and /ou/ sounds.
要特别注意/倒e/、/a/、/ao/和/ou/的发音。
Oh, hi, John, what's going on?
嗨，约翰，怎么了？
I saw that you called earlier.
我看到你早些时候打过电话。
Can you hold on for a second?
你能稍等一下吗？
I'm talking to a colleague.
我正在和一个同事谈话。
Now go back and try to count how many times you heard each sound in every sentence.
现在回去试着数一数你在每句话中听到每个音的次数。
