allow me to congratulate u on the arrival of the new year and extend to u all my best wishes for ur perfect health and lasting prosperity.may the joy and happiness around u today and always.good luck,good health,good cheer.i wish u a happy new year.

when i listened to this song below,i felt nerved and conciliative.the tune was pretty,and the lyric was illuminative.^ ^

 

"There's a hero
If you look inside your heart
You don't have to be afraid
Of what you are
There's an answer
If you reach into your soul
And the sorrow that you know
Will melt away
And then a hero comes along
With the strength to carry on
And you cast your fears aside
And you know you can survive
So when you feel like hope is gone
Look inside you and be strong
And you'll finally see the truth
That a hero lies in you
It's a long road
When you face the world alone
No one reaches out a hand
For you to hold
You can find love
If you search within yourself
And the emptiness you felt
Will disappear
And then a hero comes along
With the strength to carry on
And you cast your fears aside
And you know you can survive
So when you feel like hope is gone
Look inside you and be strong
And you'll finally see the truth
That a hero lies in you
Lord knows
Dreams are hard to follow
But don't let anyone
Tear them away
There will be tomorrow
In time
You'll find the way
And then a hero comes along
With the strength to carry on
And you cast your fears aside
And you know you can survive
So when you feel like hope is gone
Look inside you and be strong
And you'll finally see the truth
That a hero lies in you" (Mariah Carey)

when u face ur darling,ur heart may beat fast.when u face ur liker,u just feel happy.
when u face ur darling,winter is just like spring,whereas face ur liker,winter is beautiful winter!
if the one u stare at is ur darling,u will blush.but if the one u pove over is ur liker,u will smile!
when u face ur darling,u cannot blurt out all in ur mind,nevertheless to ur liker,u will say all without reserve!
when u face ur darling,u may easy to shy,but when u face ur liker,u can show true self.
darling is always on ur mind,u cannot stare at his/her eyes,but u can greet liker's eyesight!
when ur darling cries,u will melt into tears with him/her,when ur liker cries,u will stop to comfort him/her!
the feeling of love springs from eyes,but the feeling of like proceeds from ears.
so when u donnot like ur liker any more,u just plug up ur ears,but if u try to close ur eyes,the love will turn to a drop of tear,and stay in ur heart for long!

 

how time flies!!when i came back to the wongwong english forum,i felt the cet-6  might have had yesterday.but actually a half year had passed,and another cet-6 will come quickly.am i ready? i am not sure myself.a za a za fighting!!

 

our class have a barbecue at quyuanfenghe beside the west lake today,and that is a little different because you're actually prepare the food there you're grilling on the barbecue.whereas a lot of   picnics you just bring cold food you prepared at home.

the weather today is fine.the sunshine bode well for our barbedue.our class divided into two parts,one is to shopping for the barbecue,the other goes straight to the destination.ps: i belongs to the second part.we apparently got the destination early.so we go boating to kill the time.later the whole class 's arrived there,and we began grilling.of course,our grilling skill were not very good, so that many're rawness.but we still ate happily,for those were our own production.by the way,cos our school is far away from the west lake,so we had a long and tired ride.time to rest.88

today is nov. 20th.a special day for my sister rainbow,also for me.yes it is her birthday.

dear sister! i wish you happy forever.

in my eyes.you are a perfect girl: kind-hearted,pretty,tender,and your sweet voice...i donnot wanna say much.cos i wanna hide them in my heart deeply.you will be always in my heart,even if you are only just my sister.
