Hello. I'm John Russell.
大家好。我是约翰·罗素。
In previous videos, I talked about the vowels /i/ and /I/, /i/ as in he, /I/ as in is.
之前的视频中讲过两个元音/i/ 和 /I/，/i/在“he”中的发音和/I/在“is”中的发音。
I will combine them, he is.
我会把它们组合起来，“he is”。
The difference between /i/ and /I/ can be difficult for speakers of many languages.
区分/i:/和/i/的发音对于说多种语言的人来说是很困难的。
There are some similarities between the sounds.
这两种发音有一些相似之处。
Your tongue is high toward the front of your mouth for both sounds, but there are important differences.
对于这两种发音，你的舌头都是抬高朝嘴巴前方伸的，但这两种发音有很大的不同。
Your tongue is slightly higher toward the front of your mouth for /i/.
发/i/音的时候，你的舌头伸向嘴巴前面抬得会更高一点。
The sides of your tongue touch your upper back teeth for/I/.
发/I/音的时候，舌头的侧面会触碰到上牙的背面。
The most important difference is this: /i/ is a tense vowel while /I/ is a relaxed vowel.
最大的不同是：/i/是一个紧元音，而/I/是一个松元音。
To make /i/ I have to use more tension.
发/i/音的时候，我更用力。
To make /I/ I use less tension.
发/I/音的时候不需要那么用力。
Some educators like to use rubber bands to show the difference.
一些教育家喜欢用橡皮筋来表示不同之处。
You can start practicing with the vowel by itself.
你可以用它开始练习元音了。
Then try practicing with short words or phrases "he" "she" "me" "is" "ship" "fit".
然后试着用短词或短语练习如：he、she、me、is、ship、fit。
Then try words and phrases that have both sounds "he is" "feet fit" .
然后尝试有这两种发音的单词和短语如“he is”、“feet fit”。
After that, give your face a rest and drink some water.
完成之后，让你的脸休息一下，喝点水。
keep up the good work.
