13. The answer to the short passage of the vibrant sunflower One morning, the sunflower opened. Under a layer of round green leaves, three small flowers flashed out. One was red, one was yellow, and one was lavender. The blooming flowers were as gorgeous as rosy clouds, and as eye-catching as gems. In our quiet courtyard, they aroused a burst of surprise and admiration The three flowers are signals. The sound of the trumpet can't be stopped. The big flower, the small flower, the single petal, the double petal, the red, the yellow, the purple, the blue, the pink open together. A piece of green flannel turns into colorful brocade in a twinkling of an eye. Even those who don't love flowers can't stand the attraction of this beauty. When they are free, they gather around the flower bed to enjoy it From early summer to late autumn, the flowers are enduring. A piece of brocade has always kept bright and eye-catching colors. At first, we thought that the reason for this enduring is that sunflowers love the sun and can stand the test of the hot sun. Yes, it is, Only the sunflower has no reservation for the scorching sun. The hotter the sun is, the more gorgeous, enthusiastic and vigorous it is But after seeing more, I noticed that as a single sunflower, its life is very short.

Every day, there are a number of mature buds waiting to open. Before sunrise, it is wrapped tightly, and can't see the meaning of opening, but when you see the sun, Immediately open. Petals like waking up from a deep sleep. Slowly stretch out, open big, open round After that, it will enjoy the sunshine greedily and open to its heart's content. When the sunset sets, the petals will shrink again, and the flower will no longer open. The next day, it will be another batch of mature buds to welcome the sunrise How active and vivid the alternation between the new and the old is! Perhaps it is because of this that when the sunflowers bloom, they are so energetic and spare no effort. Although the life of the individual sunflowers is so short, they are always so brilliant and full of vitality on the whole The sunflowers are not depressed, and do not mean laziness. After they have finished their blooming, they will vacate the gap, give the best direction to the sun, give them new buds, and flash themselves together, gather the essence, and bring their offspring to life. They will continue to give life to the future. Until autumn frost kill, it has quietly scattered the seeds of silver seeds into the earth. In the second year, too many to count will be sprouting.
