The [i？] diphthong. I've seen some sources that leave this out altogether.
It's always followed by an R consonant， and these sources don't see the
schwa as really having its own sound， as in the ih-uh diphthong. And
I say ， I admit， I agree with that. I'm putting in here though， because
a lot of other sources use it as a separate diphthong ： ih to uh ——
schwa. Now， the first sound， ih. With many diphthongs ， I find that
the ih vowel， it's written as an open ih as in sit ， actually in the
practice of the diphthong takes on a different color. I find it to be
a lot closer to the ee as in she， though the tongue is not so far forward.
I would think of the first sound of this diphthong more as a relaxed ee
than as a pure ih as in sit. The second sound then is the schwa ， and
that sound is very quick as you are already moving into the R of the consonant
that follows. So in slow motion ， the sound， with the R ， as it is
always followed by the R， would be ： iiiiihhhhhh uuuuuhhhhhh rrrrrrr
： here.

    [i？] 是一個雙元音，有些材料中認(rèn)為這個音是[i] 和R 音的組合，當(dāng)中的
[ ？] 音并不發(fā)聲。但是還有很多材料中認(rèn)為將它看做兩個分開的元音：即[i]
和[ ？].

    對于第一個音[i] ，很多雙元音中，[i] 這個元音寫作短音，就像sit 中的
[i] ，但是真的念起來的時候并非如此，它更接近于she 中的[i：] ，雖然舌頭
的位置不像發(fā)[i：] 時那么靠前。其實(shí)這里的這個[i] 音更像一個放松發(fā)出的[i
：] 而不是純粹的sit 中的[i].第二個音便是[ ？] ，它出現(xiàn)得非常之快，剛發(fā)
出你就進(jìn)入到后面的R 音了。如果我們用慢動作來念就是這樣：iiiiihhhhhh uuuuuhhhhhh
rrrrrrr.
