Hello, I'm John Russell.
大家好，我是约翰·罗素。
Today we are going to begin exploring some of the most difficult vowel sounds for non native speakers of English.
今天我们将开始为非英语母语人士探索一些最难的发音。
Let's review the /i/ and /i:/ sounds which we have explored in previous videos.(注:此音标写法为便于编辑，正确写法见视频)
让我们回顾一下/i/ 和 /i:/的发音，我们在前面的视频中已经讨论过了。（注：此音标写法为便于编辑，正确写法见视频）
If you haven't seen those videos yet, you might want to watch them first.
如果你还没有看过那些视频，你可能想先看看。
The difference between /i/ and /i:/ is important, because mixing up the two vowel sounds can cause confusion or embarrassment.
/i/ 和 /i:/的区别很重要，搞混这两个音的发音，可能会造成误解或尴尬。
/i/ is almost always spelled with the letter "i", as in: dig.
/i/的音经常是字母“i”发出的，比如单词：dig挖。
While /i:/ is more commonly spelled with two letters, "ee" or "ea" like "feet" or "dream".
而/i:/的音则是两个字母发出的，“ee”或“ea”，比如：feet脚，dream梦想。
Remember: you should relax your lips and tongue for the /i/ sound.
记住，发/i/音时，嘴唇和舌头应该放松。
Your lips should be tense for the /i:/ sound.
发/i:/音时，你的嘴唇应该是紧绷的。
Let's practice.

For this exercise, you will need a mobile phone, computer or some other way to record your voice.
在本练习中，您需要手机、电脑或其他方式来录制您的语音。
I want you to pause the video when you see the text, and then record yourself reading the text.
我希望你们看到文本时暂停视频，然后录下自己读文本的过程。
Then compare your recording to my voice.
然后把你的录音和我的声音比较一下。
Pay special attention to the /i:/ and /i/ sounds.
要特别注意/i:/ 和 /i/的发音。
