« ce / c' » 和 一点 "法语的读音"

"这 ; 那" 是...
"that ; this" is...
"cela / ce ; ceci / ce" est...

When there's a vowel after "ce", "ce" must be « c' »
So "~ce est~" must be "c'est". (As you can say "that is" or "that's" but can't say "~this's~")
No big difference between "cela" and "ce" or between "ceci" and "ce".
"ce" is simply more used.

« { ... } » = { pinyin }
« { ~...~ } » = { ~not exactly pinyin or not pinyin at all~ }
« (...) » = (to NOT pronounce)

« - » = no liaison between the syllables.
Example ==> Gautier = { go(u) - ti ye }
{ ti ye } isn't { ti - ye } prononciate quickly, but near of { tia(n) } (infact, prononciate very very, very quickly)... ^^'

The "e" in { ye } is, in French « é ».
Its "opposition" is « è », near of { ei } but with no "i" at the end. So, 上下： { e(i) }

At last, there's two « o » in French.
{ o } 像：哦，我，博，错，末，说，找...
and
{ o(u) } 像：欧，都，够，后，就，口，六...
... there's also two « e »... but it's very complicate to write... there's the same as in "饿，了，呢..." and a sort of « eu »... ... ... ^^'
For the "e" as "饿", the mouth is like the "o" in "哦", open ; for the other "e", the mouth is like the "o" in "欧", closed.
In France, we just call these different vowels : "o ouvert" and "o fermé" ("o open" and "o closed") and "e ouvert" and "e fermé".

to be = être { ~è~ ~tr(e)~ }
I am = je suis { re - ~sv~ yi }
you are = tu es / t'es { tv - ~è~ / ~tè~ }
he is ; she is = il est ; elle est { yi - ~lè~ ; ~è~ - ~lè~ }
that is = cela est / c'est { se - la - ~è~ / ~sè~ }
this is = ceci est / c'est { se - ~sy~ - ~è~ / ~sè~ }
we are = nous sommes { nu - ~so~ m(e) }
you are = vous êtes { ~vu~ - ~z~ ~èt(e)~ } (vous = "plural" or 用的像 "您")
they are = ils sont ; elles sont { yi ~l(e)~ - son(g) ; ~è~ ~l(e)~ - son(g) }
those are ; these are = ce sont { se - son(g) }

The rule with « ce = c' » exist for "the" = "le / la" = « l' »
le = 阳性 / la = 阴性
le ciel { le - ~sy~ ~è~ ~l(e)~ } (天)
la lune { la - lv n(e)} (月)
le soleil { le ~so(u)~ - lei } (日)
阳性：l'océan { lo(u) - ~sé~ - an(g) } (海洋)
阴性：l'aube { lo(u) ~b(e)~ } (凌晨)
