舔着伤口的猫咪

人说
时间能治疗一切伤痕。

我就像被抛弃受伤的猫咪

仓惶狼狈
独自蜷缩在角落边
孤独地舔着自己的伤口
用自己的方式
企图寻找一丝慰籍。
寄望着随着时间的愈合。

人都说

时间使我们淡忘一切。


永恒的伤疤
痛楚依然

真的忘了从前的自己
为什么
伤心。

翱翔是自由的象征

没有压力的感情,
让真情流露;
零距离的触感,
心中有灵犀,
眼神交汇的瞬间,
情感不再有羁绊。

就让它在蔚蓝的上空
自由
翱翔。

飞吧!
尽情去鸟瞰无际的宇宙!

不能承受之轻

不,我不再等待。等待,疯人所不为也。

一个人的人生非得要围绕在许多等待和期盼中?

你说等待是一种艺术?等待是一门学问?

那请问你是否了解等待时候的无奈、委屈和煎熬?

一天又一天的等待,一周过去了,一个月,两个月。。。除了等,还是等。时与空擦肩而过。

期盼是无形,等待乃个人体会,两者合一,还是显得太轻。

你可以说我没有耐性。

我不能等了,也不要等了;等不了,也等不住。

因为即使等到了,也不是我的。

Fear-less

Ruined my first biology test.

.

..
...
....
.....

Should I just see it as a new golden opportunity for me to gain continuous improvement. A whole new challenge for me. Life's been boring huh?


So..


Back to zero, maybe?

#10

啊。又开学了。

不知为何,总觉得自己不是很喜欢假期。


可能是因为我对自己要求太高?


有时候真觉得自己很失败。一事无成。没有任何东西是自己最擅长的。常觉自己比他人逊色。


我却明白在这世界上,越有能力、越强大的人,背负的责任也随之变得沉重。。。


好了。晚安,世界。就让《伴》的旋律在我脑海中荡漾吧!


打起精神!面对灿烂的明天!



如果命运可以定做
如果有另一次选择
我想我还是会把手让你紧握
快乐的陪你去坎坷
就算你有天变落魄
就算你老的不能动
我想我还是会挽着你看日落
你的心疼在泪光中
嘴巴上彼此嫌麻烦
眼神中关怀那么满
没说爱却早已认定一辈子的伴
在人前从来不浪漫
在心中却总为对方打算
最懂的人最暖的伴


就算我以后变罗嗦
就算我老了有病痛
我想你还是会照顾我到最后
隐藏最弱不眠不休
嘴巴上彼此嫌麻烦
眼神中关怀那么满
没说爱却早已认定一辈子的伴
在人前从来不浪漫
在心中却总为对方打算
最懂的人最暖的伴


嘴巴上彼此嫌麻烦
眼神中关怀那么满
没说爱却早已认定一辈子的伴
在人前从来不浪漫
在心中却总为对方打算
最懂的人最暖的伴

哦
没有辛酸,没有遗憾
什么是陪伴,什么是心安
你是答案

新诗二首

我的信仰  席慕蓉

我相信  满树的花朵
只源于冰雪中的一颗种子。

我相信  三百篇诗
反复述说着的  也就只是
年少时没能说出的
那一个字。

我相信  上苍一切的安排
我也相信  如果你愿与我
一起去追溯
在那遥远而谦卑的源头之上
我们终于会互相明白。


我爱这土地  艾青

假如我是一只鸟,
我也应该用嘶哑的喉咙歌唱:
这被暴风雨所打击着的土地,
这永远汹涌着我们的悲愤的河流,
这无止息地吹刮着的激怒的风,
和那来自林间无比温柔的黎明。。。。。。
然后我死了,
连羽毛也腐烂在土地里面。

为什么我的眼里常含泪水?
因为我对这土地爱得深沉。

Ionic or Covalent?

ELECTRONEGATIVITY

This page explains what electronegativity is, and how and why it varies around the Periodic Table. It looks at the way that electronegativity differences affect bond type and explains what is meant by polar bonds and polar molecules.
If you are interested in electronegativity in an organic chemistry context, you will find a link at the bottom of this page.

What is electronegativityDefinition
Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons.
The Pauling scale is the most commonly used. Fluorine (the most electronegative element) is assigned a value of 4.0, and values range down to caesium and francium which are the least electronegative at 0.7.

What happens if two atoms of equal electronegativity bond together?
Consider a bond between two atoms, A and B. Each atom may be forming other bonds as well as the one shown - but these are irrelevant to the argument.
If the atoms are equally electronegative, both have the same tendency to attract the bonding pair of electrons, and so it will be found on average half way between the two atoms. To get a bond like this, A and B would usually have to be the same atom. You will find this sort of bond in, for example, H2 or Cl2 molecules.


Note:  It's important to realise that this is an average picture. The electrons are actually in a molecular orbital, and are moving around all the time within that orbital.


This sort of bond could be thought of as being a "pure" covalent bond - where the electrons are shared evenly between the two atoms.

What happens if B is slightly more electronegative than A?
B will attract the electron pair rather more than A does.
That means that the B end of the bond has more than its fair share of electron density and so becomes slightly negative. At the same time, the A end (rather short of electrons) becomes slightly positive. In the diagram, "" (read as "delta") means "slightly" - so + means "slightly positive".
Defining polar bonds
This is described as a polar bond. A polar bond is a covalent bond in which there is a separation of charge between one end and the other - in other words in which one end is slightly positive and the other slightly negative. Examples include most covalent bonds. The hydrogen-chlorine bond in HCl or the hydrogen-oxygen bonds in water are typical.

What happens if B is a lot more electronegative than A?
In this case, the electron pair is dragged right over to B's end of the bond. To all intents and purposes, A has lost control of its electron, and B has complete control over both electrons. Ions have been formed.

A "spectrum" of bonds
The implication of all this is that there is no clear-cut division between covalent and ionic bonds. In a pure covalent bond, the electrons are held on average exactly half way between the atoms. In a polar bond, the electrons have been dragged slightly towards one end.
How far does this dragging have to go before the bond counts as ionic? There is no real answer to that. You normally think of sodium chloride as being a typically ionic solid, but even here the sodium hasn't completely lost control of its electron. Because of the properties of sodium chloride, however, we tend to count it as if it were purely ionic.


Note:  Don't worry too much about the exact cut-off point between polar covalent bonds and ionic bonds. At A'level, examples will tend to avoid the grey areas - they will be obviously covalent or obviously ionic. You will, however, be expected to realise that those grey areas exist.


Lithium iodide, on the other hand, would be described as being "ionic with some covalent character". In this case, the pair of electrons hasn't moved entirely over to the iodine end of the bond. Lithium iodide, for example, dissolves in organic solvents like ethanol - not something which ionic substances normally do.

Summary
  • No electronegativity difference between two atoms leads to a pure non-polar covalent bond.
  • A small electronegativity difference leads to a polar covalent bond.
  • A large electronegativity difference leads to an ionic bond.

Polar bonds and polar molecules
In a simple molecule like HCl, if the bond is polar, so also is the whole molecule. What about more complicated molecules?
In CCl4, each bond is polar.


Note:  Ordinary lines represent bonds in the plane of the screen or paper. Dotted lines represent bonds going away from you into the screen or paper. Wedged lines represent bonds coming out of the screen or paper towards you.


The molecule as a whole, however, isn't polar - in the sense that it doesn't have an end (or a side) which is slightly negative and one which is slightly positive. The whole of the outside of the molecule is somewhat negative, but there is no overall separation of charge from top to bottom, or from left to right.
By contrast, CHCl3 is polar.
The hydrogen at the top of the molecule is less electronegative than carbon and so is slightly positive. This means that the molecule now has a slightly positive "top" and a slightly negative "bottom", and so is overall a polar molecule.
A polar molecule will need to be "lop-sided" in some way.

Patterns of electronegativity in the Periodic TableThe most electronegative element is fluorine. If you remember that fact, everything becomes easy, because electronegativity must always increase towards fluorine in the Periodic Table.


Note:  This simplification ignores the noble gases. Historically this is because they were believed not to form bonds - and if they don't form bonds, they can't have an electronegativity value. Even now that we know that some of them do form bonds, data sources still don't quote electronegativity values for them.



Trends in electronegativity across a period
As you go across a period the electronegativity increases. The chart shows electronegativities from sodium to chlorine - you have to ignore argon. It doesn't have an electronegativity, because it doesn't form bonds.

Trends in electronegativity down a group
As you go down a group, electronegativity decreases. (If it increases up to fluorine, it must decrease as you go down.) The chart shows the patterns of electronegativity in Groups 1 and 7.

Explaining the patterns in electronegativity
The attraction that a bonding pair of electrons feels for a particular nucleus depends on:
  • the number of protons in the nucleus;
  • the distance from the nucleus;
  • the amount of screening by inner electrons.


Note:  If you aren't happy about the concept of screening orshielding, it would pay you to read the page on ionisation energies before you go on. The factors influencing ionisation energies are just the same as those influencing electronegativities.

Why does electronegativity increase across a period?
Consider sodium at the beginning of period 3 and chlorine at the end (ignoring the noble gas, argon). Think of sodium chloride as if it were covalently bonded.
Both sodium and chlorine have their bonding electrons in the 3-level. The electron pair is screened from both nuclei by the 1s, 2s and 2p electrons, but the chlorine nucleus has 6 more protons in it. It is no wonder the electron pair gets dragged so far towards the chlorine that ions are formed.
Electronegativity increases across a period because the number of charges on the nucleus increases. That attracts the bonding pair of electrons more strongly.
Why does electronegativity fall as you go down a group?
Think of hydrogen fluoride and hydrogen chloride.
The bonding pair is shielded from the fluorine's nucleus only by the 1s2 electrons. In the chlorine case it is shielded by all the 1s22s22p6 electrons.
In each case there is a net pull from the centre of the fluorine or chlorine of +7. But fluorine has the bonding pair in the 2-level rather than the 3-level as it is in chlorine. If it is closer to the nucleus, the attraction is greater.
As you go down a group, electronegativity decreases because the bonding pair of electrons is increasingly distant from the attraction of the nucleus.

The polarising ability of positive ionsWhat do we mean by "polarising ability"?
In the discussion so far, we've looked at the formation of polar bonds from the point of view of the distortions which occur in a covalent bond if one atom is more electronegative than the other. But you can also look at the formation of polar covalent bonds by imagining that you start from ions.
Solid aluminium chloride is covalent. Imagine instead that it was ionic. It would contain Al3+ and Cl- ions.
The aluminium ion is very small and is packed with three positive charges - the "charge density" is therefore very high. That will have a considerable effect on any nearby electrons.
We say that the aluminium ions polarise the chloride ions.
In the case of aluminium chloride, the electron pairs are dragged back towards the aluminium to such an extent that the bonds become covalent. But because the chlorine is more electronegative than aluminium, the electron pairs won't be pulled half way between the two atoms, and so the bond formed will be polar.

Factors affecting polarising ability
Positive ions can have the effect of polarising (electrically distorting) nearby negative ions. The polarising ability depends on the charge density in the positive ion.
Polarising ability increases as the positive ion gets smaller and the number of charges gets larger.
As a negative ion gets bigger, it becomes easier to polarise. For example, in an iodide ion, I-, the outer electrons are in the 5-level - relatively distant from the nucleus.
A positive ion would be more effective in attracting a pair of electrons from an iodide ion than the corresponding electrons in, say, a fluoride ion where they are much closer to the nucleus.
Aluminium iodide is covalent because the electron pair is easily dragged away from the iodide ion. On the other hand, aluminium fluoride is ionic because the aluminium ion can't polarise the small fluoride ion sufficiently to form a covalent bond.

Best feelings in the world    : Emotionally attached to someone

Worst feelings in the world  : Emotionally attached to someone

#5

Dear alter-ego.

Hope that your intense and overwhelming feelings do not overwrite my rationality anymore.


No more shouting at my best buddies in college.

No more upsetting the only bear I've ever had.

Be more level-headed. You don't wanna lose them...


I tell you why, Adrian. Consider yourself the luckiest person in the world. You have met a group of warm-hearted, sensible, truthful, strong-willed and caring FRIENDS. 


I understand, that you are very grateful.

You would have ended up alone, if it weren't for them.

Now you are a more contented and happier person at college, mostly because of them.

The inner heart knows well. These are the people whom you can treasure in life.


Be strong. Improve myself continuously. Be an asset to them. Each of them aspires to be the bestest figure in the world. Lend them your fullest strength. Let them be the thriving serpent in the deepest depth of water, and also the soaring eagle in the sky.


#4

HATRED.

LEAVE THEM ALONE. DON'T LET IT CONSUME YOU. LET YOUR HEART AND SOUL AT PEACE.

I hate myself.

#3 Priority First

Life With Priority. Live it. Embrace it. 

There are so many things in this world that we cannot possibly attend to all the details in life.


Instead, choose a few things that we value the most. 


They can be our beloved family, our best friends/ companion, work, hobbies or even aspirations! Focus on them. Commit to them. 


After all, they mean the most to us , don't they? 


In life, priority often guides us to do the right thing at the right time. 

In addition, when we are faced with multiple situations in life, it helps us to know how much energy we should put in each task, and the sequence of the plan, so that we end up completing both. 
Most of the time, our values affects our decision when facing a dilemma. 

On the other hand, priority reminds us to balance between life, work and family. When we overdo work, it makes sure that we eventually fall back to our priorities. No valuable time is wasted on excessively meaningless work.


It also helps to know your priority by setting aims in life, as well as your future ambition. When you understand your goals well, you'll know what important task that needs to be prioritized, in order to to attain the goals. 


Another aspect is the development of our inner self. 


[For example, when you aspire to be a great politician, you are bound to have excellent communication skills (and many more). Therefore, one of your priority should be training up your public speaking skills during your study life.]


Priority enables us to be the master of our time.


Allocate time to meaningful things that can make you feel truly happy and accomplish life. 

To know whether something is "meaningful", just ask yourself- Ten years from now, will it count for anything? Any significance of it to life? 

Different people will have different set of priorities in life (Every person has their own internal value system). It depends solely on what matters most, to you. Sometimes priority comes with own principles of life.


The point is, you will feel simply happy with what you are doing. Because you are living a life that you truly yearns for, at the same time doing things that you truly love and care for from deep inside your heart.

Till then, know your priorities in life. It greatly helps to propel us to living a more fulfilled life.

A lot of motivation!

叮当- 我是一只小小鸟


Be brave. Seconds of courage can certainly change your decision, and hence, your life and destiny.


Mariah Carey - Hero



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 your 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

Lord knows
Dreams are hard to follow
But don't let anyone
Tear them away
Hold on
There will be tomorrow
In time
You'll find the way


曲婉婷- 我的歌声里



你可以已经消失在我的世界里,但是你依然,永远存在我深深的脑海里,我的梦里,我的心里还有我的歌声里。


Celine Dion- That's The Way It Is


Specially dedicated to everyone and everything in this world that I'd come to love :)


Mariah Carey- Bye Bye


The hardest thing to do is say bye bye to the closest people in life.

最虚假的感情


远处,
茫茫人海中,
你的身影,
是如此熟悉,
那是曾经。

目光深邃忧伤,

深切地感受到,
你双眸的呼唤。
爱的呼唤。

你的双眸,

异于常人,
白色湖泊中央,
是明月的倒影,
皎洁且明亮。
四季如春朝气蓬勃,
纯真的笑意,
快乐的光芒,
成熟中带有稚气,
但,
微笑背后,
却是道不尽的悲愁。

你的双眸

极美。

擦肩而过。

寻寻觅觅。
刻意
选择逃避,
我明白,
隐藏的泪水,
终会决堤。

而今,

你的双眸,
已是冰霜豪雨的季节,
湖水平静不再,
巨浪汹涌,
泛起红色涟漪。
往昔的热情,
换来缕缕伤悲,
夹着百般无奈,
亦是彷徨,
悲从中来。

你的双眸,

冷冰冰。

宏,

一切是我造成的?
除了懊悔还是自责愧疚。
我明白
脆弱的心
载不动
千千万万个
无法释怀的歉意。

昔日的甜蜜,

不堪回首。
满腔的辛酸,
欲语泪先流。

聆听我真诚的祷告,

让这一切
成为永远的神话
但愿
钟子期能再生!
重新开始

。。。。。。


清晨的曙光,
我等你好久了。

:))
