## Give Up Sometimes

The expression “Never, never give up” means to keep trying and never stop working for your goals. Do you agree or disagree with this statement? Use specific reasons and examples to support your answer.

Topic

Many people believe in the saying that we should never give up casually, which tells them to work incessantly for their goals. Admittedly, this spirit-lifting saying has given countless people a pat on the back, inspired them to strive for their long-held dreams and acquire prosperity in the end. But generally speaking, I suppose we don’t have to shy away from giving up. Sometimes we need to put aside our persistence and accept the abnegation.

First of all, the initial orientation matters. We can’t guarantee that the first step we take is towards the right direction, which means we can be heading the wrong without perceiving it. If so, it would be better to just turn around than to press on. There’s no need to sacrifice your success for simply senseless insistence. One example of this is an ancient idiom from China, narrating a man who intended to go south steered his carriage to the north regardless of the prompting from a passer-by. He had not realized the sheer meaninglessness of his action. Of course, he has not arrived his destination yet. Had he listened to others’ advice and turned back, he would have reached it.

Besides, we should pay heed to the progress. Not only are we likely to move forward to where we do not expect at the beginning, but also during the process, and thus adjusting ourselves dynamically should be attached significance to. In addition, even though we know clearly what we are doing and why we are doing it, we may lack the capacity to do it well, and the progress can fall short of our expectation. When we’re patently unsuitable for tackling certain type of things, insisting may not be the optimal option. Some classmates in my high school will be rather representative instances. As soon as they entered the school, each of them picked an Olympiad in a certain subject. Yet before long, they found themselves not very good at competition, thereby opting out, focusing on regular curriculum. It turned out ultimately that they obtained fairly high scores in the college entrance examination. We can derive from it the fact that giving up does not necessarily mean losing, but somehow means wining.

What’s more, the outcome may be perplexing. When it come out, it’s time to judge whether it is right or not. We can scarcely ensure that the result will always fulfil our anticipation, so when we receive an unexpected result which is against the basic facts, probably it should not be calculated in statistics. At this time, alleging that the result has no problem seems a bit stubborn. On the other hand, if the result does not correspond with what we used to deem it should be, the chances are what deceives you is not the result, but the acknowledgement. If we look back upon history of science and technology, there are innumerable examples, such as Galileo who doubted the previous law of free fall, Bohr who suspected the previous nuclear model, etc. All of these indicate that even the most seeming truth has the possibility to be broken someday. The interesting thing is that, the result and the truth were dropped alternately, which set the pace for the development of human civilization. We wouldn’t have today’s advancement if there were no giving up in the world.

The old saying “Never, never give up” will continue to exert its positive attitude and lift people up. However, I take the viewpoint that people sometimes need to give up what they think, have or believe. This is not persuading you to give up everything in your life, but encouraging you to give up in a more sensible way, in which you will better encounter what you love, accomplish what you dream, and make what you desire to be.

## Spring II

It was a surprise to discover a new nest opposite the window.

Through the telescope, I scrupulously watched the doves in the nest, who were reposing restfully. Narrowly I discerned that they were a family comprised of a mother and two babies. Sighing with relief, I thought, “Finally the dove has returned, and luckily I can still see the family.” I even expected to witness the first flight of the baby doves.

I started wondering where the doves came from, as it was odd that they were inclined to construct their home here between the buildings, and after a period of cogitating, I ultimately deduced that once they might live in the decrepit houses nearby which were to be pulled down owing to the modernization and urbanization.

From this viewpoint, the doves seemed to be pitiable. “It can be tough for them to find a congenial shelter in the city.” I uttered in my heart, as I observed them fluttering their gray wings. It looked as if they were enjoying the serene life. Yet my brain did not cease contemplating.

Living in the era with rapid technological advancements which largely hasten our pace of life, we ineluctably forgo the joyous time being close to nature. And not until the demise of the erstwhile happiness we attained from nature comes do we realize that it is deplorable to turn ourselves into a hardened machine.

The blood-red sun was sinking and a livid cloud in the east received its rays. A twinge of woe surged through me. If we humanity kept pursuing interests by damaging the environment, what would the attendant consequence be? Would it only be driving the doves homeless?

I couldn’t help recalling the days when the city was shrouded in thick smog, and people could scarcely distinguish the things in the distance. And the rivers in the city, which were limpid before, had become turbid in recent decades. The foregoing instances were attributed to human activities. Not to mention the global warming, the ozone depletion, and the extinction of multitudinous species. Urbanization was just all of these in miniature.

The sky was tinted with black inch by inch, and the doves quieted down again. I shifted my eyes from them.

I leaned on the windowsill, looking up at the firmament, which used to be spangled with innumerable stars that were now unseen to us. Embedded aloft in the inky night sky, the pale yellow full moon cast its glow over the city, like an infinite piece of cloth mantling, yet faraway as the neon lights were, their harsh beams penetrated the textile that the moon carefully sewed without any difficulty, as if it was nonexistent. The dazzling rays pricked not only my eyes, but also my heart. “Perhaps the doves dread the blinding light, too.”

There was a time when all the doves could flit from tree to tree jovially in the dense and emerald woodlands, where they interacted with other creatures complying with the principles of nature. It was not until human beings arose that changes occurred. Trees were felled at first, and then sewage and fumes were disgorged by pipes. As the time elapsed our compunction was attenuated unawares by the profits we gained at the price of the environment we lived. We averted our gaze from what was prime, focusing on what was subordinate. The cupidity for gain and the scant heed we paid to conservation incurred the mire we confront today.

We really should pause, ruminate for a while, and inquire ourselves, what is our original orientation, and does what we endeavor to do diverge from that aim. Is our purpose to make every hue around us grey? Or to fetter ourselves in the forest of reinforced concrete? Or, to alter the earth to meet human’s multifarious demands regardless of the sustainability?

The onus is on us to maintain an agreeable environment. We need introspection, though it may seems arduous to atone for the devastation.

Fortunately, we gradually awake to the pernicious effects, and we are making a change. Eco-civilization construction has been put forward, and the departments concerned are sparing no effort to ameliorate the imbalanced ecology.

It was late spring, and every plant was flourishing. I heard the birds warbling a mellifluous night chorus, my heart mollified.

I entertain the hope that one day, we can thoroughly relish the felicity from nature. I envision an unspoiled environment. If we esteem nature, make optimal decision, and take prompt action.

I’m looking forward to the arrival of that very day.

## Spring I

I heard something twittering on the balcony.

Walking on my tiptoe, I reached the window, through which I spotted a turtle dove standing on the stainless-steel-made railing, with a sprig in its beak. Barely had I observed it attentively when it hastily fled away, leaving behind a fuzzy silhouette.

I was leaning on the windowsill, looking down, when a ball of white captivated me, which I instantly recognized as peach blossoms. Bathed in radiant sunlight, they stretched their exquisite bodies in all directions. The balmy breeze gently swayed the flowers, carrying the scent they exuded wherever it passed. Eventually here came the spring. As I was about to return to my room, my eyes rested on a half-finished bird nest that lay on the board put on the railings.

It was unbelievable that the dove was planning to build a nest on our balcony. Yet this was the case. What’s more, I witnessed two doves erecting their lovely home together. Before long, a complete nest came out.

I could see in the mild twilight, a tiny nest lying steadily behind the huge flower pots, and an adorable dove perching on the nest. The setting sun cast its silky beams on this little cute creature through the verdant plants in the pots, resembling a warm hand patting tenderly. This tranquil scene was set off by the distant golden horizon, which formed the most enchanting landscape in the world. I could picture that under its little body, eggs were being warmed up, and new life was being brewed.

But we all know that good times do not last long, which I grasped on that drizzly evening when the dove had gone away and had not returned.

I stared at the empty nest vacantly, a sense of loss welling up in my heart. There lay the sole egg placidly, reflecting the cold light which the moon shed on the earth. Why didn’t the dove return? Maybe, I unintentionally frightened it, or, it had found a superior habitat. But, did it desert its cherished egg? On this fairly chilly rainy night, where could it go? Would it be shivering all over in the freezing wind? As the moonlight suffused the ground, I perceived that, never would I know the answer.

I leaned on the windowsill, overlooking the swaying flowers. I could hear raindrops knocking the canopy, composing a rumpled melody agitating my thoughts. I could see them trickling down the eaves, descending, sinking into puddles, feebly splattering a spray of droplets. Also I could hear the moaning wind dashing through the alley, wildly rattling loose windows and doors. I could see it wobbling the leaves furiously, severing them from branches and tugging them down. But, in the meantime, I could see the blossoms that the tree threw up in the air, being hit by the rain and being swung by the wind, while they kept emanating aroma that wafted all around. I could see the myriad scattered petals which fell on the moist tarmac, all colors draining rapidly, yet somehow, they were peculiarly appealing with the lamplight flickering in dewdrops.

It suddenly occurred to me that, unlike what I considered before, what was called spring, was not a picture in a particular style. It not only meant arrival and growth, but also meant departure and wilting to some extent.

So the spring is not all about a couple of turtle doves who are busy constructing a cozy neat twiggy nest where the new life will be brought, nor about the pale pink blossoms that bloom wherever you behold, adorning the corner of the bright blue sky. The essence of the spring lies in the persistence that the doves possess, even if they get so close to human beings and lose one of the only two eggs. It lies in the patience with which the dove squats in its nest unceasingly, awaiting the arrival of the baby, no matter the icy drizzle and the roaring gale. It lies in the optimism which encourages the blossoms to bloom vigorously in the frigid sprinkle. It lies in the devotion of the blossoms as they make the world transfigured despite the adversity they are confronted with.

I lingered on the balcony, hearkening wind and rain, dismay dissipating gradually. And here came the spring. I could sense that, distinctly.

## The Beginning

The bell is about to ring. The new year is in sight.

Time flies as we grow and mature, leaving naivety behind. No sooner have we relived the past year in detail than we face the coming year hurriedly. Lay down the heavy burden, repack the travelling bag, take our initial dream, step forward readily and firmly.

It’s said those who have received compliments should be rather careful, for other’s acclaim may block the consciousness of weakness, which surely leads to failure. Yet by no means shall we belittle ourselves, since nobody will have confidence in us unless we are confident. Owning a distinct understanding of oneself, cultivating the better part, remedying what have been done that turns out a mistake, are ways to adjust our mentality.

When we gaze at the vast, dark night sky, sparsely-arranged stars hang high, whispering about what they have just witnessed on this tiny, lonely, but vigorous cerulean planet, such as a large amount of teenagers burning the midnight oil, waiting for that extraordinary moment, after which they may become an adult, or may bare his or her heart to someone else, or, may just sigh with the feeling that it seems something in life, which is hard to be aware of, has vanished silently and drastically. Whatever they see, the sparkling stars keep extending their best wishes to whom they have not known and may never know. The stars, the glinting stars, the stars that split the profound night sky, for how long will we still be able to look up at you?

When we overlook the pure white snowfield, accumulated snowflakes lie serenely, mirroring the warm, golden light that streetlamps cast, illumining the bottom of passers-by’s hearts, which originally filled with some annoying things, like working overtime without gaining anything, or getting into a conflict with someone he or she considers dearest, or, biting, frigid wind blowing right into cheek, as if thousands of sharp knives are pricking the skin. But at the time, the light disperses the dust, and pushes the haze in the heart aside, bringing peace and quiet, awakening hope for the future, for the year approaching. The snow, the crystal snow, the snow that decorates the empty city streets, will you still be here years later?

No matter how we get through the year just past, it doesn’t make any sense to immerse in the memory. We shall always look forward, but don’t forget, up in the sky, down on the ground, there must be someone else, caring you, supporting you, giving you hope whenever it seems impossible.

Anyhow, it’s a brand new beginning.

Goodbye, 2018. Hello, 2019.

## Light III

He could feel drizzle patting his face.

To the best of his ability, he stood up. Anew, darkness enveloped him.

He pondered about what he had just experienced, which was patently a dreadful nightmare. Yet everything was so real, that he couldn’t persuade himself not to recall that dream.

In a moment, he caught sight of something in the distance, something that was gigantic enough to be seen. It was hard for him to put down the desire to approach it. He started padding, but he sensed something preternatural. As if he was walking through a long narrow corridor, in which there was solely enormously faint light.

When he finally reached the thing, he was astonished to find that he was facing a boundless wall which was clearly insurmountable. Scarcely had he had time to figure out what was happening when he was sucked into an exceedingly strong whirlpool, losing his consciousness.

He was astounded again when he opened his eyes.

In his sight there turned seasons. He could see fresh green seedlings protruding, carefree swallows singing and dancing freely in spring, and the brilliant sun creeping up gradually, tiny trees slowly growing to a huge proportion during summer, and with autumn coming the golden foliage fell, embellishing the azure blue sky, and before long clean white snowflakes began to appear, which indicated that winter had reigned the ground. It was quite amazed that he was able to recognize the various colors in no time, as well as the weathers he used to feel and the planets passing over head. What he once could only heard of was just in front of him, like an ancient but exquisite picture scroll opening before his face by degrees. Wherever his vision went, the superb landscapes appealed to him.

He was immersing himself in this fabulous world when in an instant, as if a heavy gate was opened, recollections flooded his brain.

He attempted to cast his mind back, and something mysterious occurred.

He could see his father holding him in his arms, while his mother cradled his brother, staring at two little lives, humming a familiar song he had heard for many times. He could see he and his brother climbing up and down at home, and his brother frequently lending him a hand without which he might have fallen off the table that was still higher than him. He could see the family outing, during which his relatives did not get weary of guiding him, telling him what was going on around, such as fragrant flowers dancing with colorful butterflies. So joyful was he at that time that as he thought, in his heart a knot was untied, and the ice melted.

Never had he realized that so many fantastic memories had been missing since his third birthday, for which he would have lived delightedly, appreciating the love and hope on earth, summoning up the courage and confidence, to strive for an entirely different life.

But it was said there was no sense crying over every mistake, for what had been done was unchangeable. He smiled, blandly, as he floated in the air, higher and higher.

Looking down, he saw himself, just lying, peacefully, on the snow-covered ground.

“There lies a wall, up to the heaven, down to the hell, left to infinity, right to where you cannot see.”

“This wall is called death.”

“Only when a person is confronted with this wall will he look back upon his entire life.”

## Light II

He had no idea where he was.

And a strong feeling that he had never experienced before occupied his mind little by little.

The light was still there. So dim and nebulous was it that the dread of being encircled again by the darkness swiftly crept up from the bottom of his heart. Though he managed to shift his feet with all his strength, he could hardly budge an inch.

Brimming with confusion, he cast a glance at the ground, but only to find blur in his sight. Apparently he was trapped in a funny dream, which was made up of what he had sustained in reality.

Weak as it was, the light still produced warmth like the sun. He knew clearly the sensation of basking. The sunlight was gentle and mild. The feeling of extreme familiarity brought him back to his childhood.

He vaguely remembered that all around him were glee and thrill when he was a infant. Often his parents took him out, holding him in the arms, bathed in the sunshine. Pure and innocent, he enjoyed everything he heard, smelled, touched and tasted, not being aware of the fact that there existed something called vision, which he later thirsted for.

In his memories, his parents never loved him. Oh, maybe they were, before his third birthday. It was unbelievable that a three-year-old little boy could bear so many things in mind such as hearing a baby’s weep and his parents’ mirth, as well as realizing his disability, which had bothered him for what seemed like centuries. In fact, the voices kept reverberating in his mind, and continued pushing him to the verge of collapse. He considered that day a turning point of his life.

“My third birthday.” he smiled wryly, “My last birthday.”

He had no intention, and did not willing, to grumble at his parents. What made all the things transpire was his blindness. Even he felt guilty, and believed that himself was to blame. It was him that let his parents down, and that lost courage to live. It was his disadvantage that made him an object of ridicule, and that surrounded him with the deepest darkness. Had he not been blind, everyone would have lived a better life.

Few merry moments could be found in his recollections afterwards. Or maybe.. he pretended to have forgotten them?

He did not stop searching in his memories until the light began to peter out. His mental pain slightly alleviated as he pulled himself out of mind-wandering.

But an old saying told by his grandpa suddenly emerged in his brain, which sent shudder down his spine, “Only when a person is about to depart this world will he look back upon his entire life.”

For the first time in his life, his heart was seized by such unimaginable fear, and it nearly ceased bounding.

And there went off the light, silently, remaining darkness.

## Light I

He was born blind.

He had suffered the darkness for years which he had been accustomed to, till that day, when something mysterious happened.

Abruptly he felt a soft, faint beam pierced the darkness, which seemed to be a firefly in the air, a lighthouse on the sea. Confused and attracted though, he got a sense of scare and decided not to move his feet, since he had never seen even a glimmer of light before.

In an instant the star-like light brightened, and it started twinkling. His curiosity aroused, he slowly groped his way towards the source, even if he couldn’t see it clearly. “The light is so gentle.” He thought to himself.

He recalled the period when he was surrounded by absolute darkness. It was not until his third birthday that he was told the earth was full of gorgeous scenery which he wasn’t able to witness, however he hadn’t got the point and he still lived joyfully. But gradually he had no notion of what people were talking when they chatted about weathers, landscapes, and even colors. This beset him a lot, and at last, he conceded the adversity reluctantly.

He had plodded for… how long? He couldn’t tell accurately, but he was depressed by the discovery of the fact that it was still a long distance from where the light was emitted.

Drooping his head with a sigh, he slowed his pace, disheartened. “Why should I undergo all of these?” A disgruntled thought flashed in his heart, and he couldn’t help asking.

That people queried the cause of his blindness was one of his antipathies. He had many antipathies, for instance, talking to others, but that was the very one he detested most, for always he was laughed at and was played a trick on at school, which made him consider everybody untrustworthy.

But he continued dragging himself to the light, as if he was driven by an invisible force. His mind in a turmoil, he couldn’t concentrate. He submerged himself in the past.

Was there anyone caring about him? He didn’t know, yet he would like to believe there wasn’t.

Occasionally he had a strong desire to leave this unlit world, the world with no hope, no laughter, and no happiness, to which he deemed himself useless. He was convinced of the sheer meaninglessness of life, and regarded every day as suffering. He even thought up a method. Maybe… jumping off something was a practical choice?

However, the explanation for the existence of this light remained a mystery. He didn’t care about this. He merely wished to see the source only once, which gave out light that he had yearned for for long. His ears were replete with winds, as he was rushing so fast—he found himself flying in the air.

And ultimately, he fell, asleep.

Yet light was there, still, inside his heart.
