① Wisteria Falls

Zong Pu

I can't help but stop.

I have never seen such a blooming vine. I saw the splendid lavender hanging down from the sky like a waterfall, its beginning and its end. Just a deep and shallow purple, as if flowing, laughing and growing. On the big purple banner, there is a little silver light, just like the splash of A (splash, splash, splash). A closer look shows that it is the brightest part of each purple flower, and the sunshine is B (setting off, teasing, teasing).

The spring flowers here have withered, no one appreciates the flowers, and there are no butterflies around the bees. Some are sparkling and blooming vines on this tree. Flowers are next to flowers, one after another, pushing each other around, so lively!

(4) Each ear of flowers blooms above and waits for release below. The color is light and dark, as if purple has settled down and settled in the tenderest and smallest bud. Every blooming flower is like a small full sail, with a sharp cabin under the sail and a bulging cabin; It's like a smile that can't help laughing, and it's about to bloom. What's the fairy dew and honey? I leaned over and picked one.

But I didn't pick it. I have no habit of picking flowers. I just stood and stared, feeling that this wisteria waterfall was not only in front of my eyes, but also flowing slowly in my heart. Flowing, taking away the anxiety and sadness that have been pressing on my heart these years. This is a secret about life and death and brotherhood. I am immersed in the brilliance of this dense flower, and there is nothing else for the time being, only peace of mind and happiness of life.

⑥ In addition to the brilliance, there is a faint fragrance here, which seems to be light purple, and it covers me gently like a dream. It suddenly occurred to me that there was a big wisteria outside my house more than ten years ago. It climbed high beside a dead locust tree, but the flowers were never sparse. A bunch of flowers hung on the treetops of things alone, as if observing and testing something. Later, even the sparse flower clusters disappeared. Other wisteria frames in the garden were also pulled down and fruit trees were planted. At that time, it was said that there was an inevitable relationship between flowers and life corruption. I once thought regretfully: There are no vines here.

All landowners after so many years, the vines have blossomed again, so abundantly and densely. The purple waterfall covers the thick branches of the disc, and it keeps flowing, flowing and flowing to people's hearts.

Flowers and people will encounter all kinds of misfortunes, but the long river of life is endless. I touched the little purple flower hut, which was filled with the wine of life. It is full of sails, sailing on the river full of flowers. It is one of ten thousand flowers, and it is by each flower that a splendid ten thousand flowing waterfall is formed.

Pet-name ruby in the faint purple light and faint purple fragrance, I feel to speed up the pace.

(2) Applause for the first time

Qin Wenjun

There is an ordinary house with a yard near my home, and the hostess is a little precocious. Her yard is full of flowers, and sometimes the hostess will pick some flowers and put them in a bucket to sell at the door. I once bought red carnations and yellow roses there. I could see her gardener's rough hands when she handed me the bouquet.

One evening, I passed by and saw two roses blooming brilliantly in the yard. Their petals are as red as flames, and I pointed to them and said I want them. The hostess shook her head and said that she would pick the best two roses every year and give them to her two daughters in the distance. The hostess's husband is an honest man. He complained that his wife was too backward, so he thought it would be better to sell the flowers and send a pack of rose petals to his daughter. But the hostess stubbornly shook her head, and her eyes flashed with shyness that was not commensurate with her age.

(3) The next morning, I passed by the courtyard where flowers were in full bloom. The hostess guarded two picked red roses, and her face was full of love. The true feelings reveal a kind of crystal clear beauty. I can't help telling her: I am very touched, and I am cheering for her in my heart.

The hostess was surprised. She didn't say a word in her slightly parted lips, and didn't even find her reading glasses slipping. Then, when she saw me again, her eyes were full of kindness. Once she insisted on sending me a bunch of yellow roses and said, "No one has ever said that about me." I went home and counted the roses. I gave one of them to the beautiful girl downstairs, and the remaining nine were put in vases. Those nine roses represent my inner hope: let each of us be happy forever in life. Because I know exactly what each applause means to a person.

Wandering in the long river of life, everyone will feel that they have no weight and will be washed away by fate. If there is an exciting voice at this time, maybe this person will become a mountain. Some people compare life to a ball game. How wonderful the game would be without sincere applause from both sides! I remember in junior high school, I had a deskmate. Her teeth are crooked. She curses like a boy and slaps mosquitoes like clapping her hands. I don't like her rudeness We sat side by side, but we didn't talk for half a month.

⑥ In a composition appraisal, one of my excellent works didn't win the prize and fell into Sun Shan. I was disheartened and tore my composition to pieces with frustration. At this moment, my tomboy deskmate suddenly made an angry voice. She said that the composition was well written, and whoever tore it was blind.

7. She was actually being sarcastic and expressing her applause to me. It was the first applause in my writing career, and it was tantamount to giving me a hand. I remember crying at that time.

The deskmate still keeps his belligerent temper. We often quarrel, challenge and resent each other. However, I still can't forget this person, because her first applause is like a ladle of water of life, which makes the almost withered ideal seed in my heart sprout again, blossom and bear fruit. Moreover, when I look back, I will regret why I didn't treat her more gently, because she is a bright sunshine in my life.

Pet-name ruby people often come to thank me, saying that my affirmative words made his eyes clear. In fact, I have long forgotten that I bought lottery tickets for him. However, that is neither painful nor itchy. When we see the bright colors in other people's lives, we might as well cheer loudly. This not only makes each other perfect, life full of love, but also broadens our hearts. Because only honest and enthusiastic people will sincerely cheer for others.

Paragraph 2 1. ② It is said that the hostess picks the best roses for her distant daughter every year, but her husband thinks it is meaningless to send flowers to her daughter, and it is more affordable to sell them. Do you agree with the hostess or her husband? Please briefly explain the reasons. (2 points)

24. What kind of wishes did the author express in the article? Please briefly explain. (2 points)

25. Pick out a sentence that you think is the most beautiful from the text, copy it neatly, comment on it again, and tell me what's good about it. (2 points)
