2. Reading Comprehension (40 points)

(1) Read the following passage and answer the questions that follow. (9 points)

Why are the flowers so red? From Darwin’s theory of natural selection, insects play an important role. Billions of years ago, when gymnosperms appeared on the earth, there were not many insects. The flowers are lightly pigmented and depend on the wind for pollination. They are all wind-pollinated flowers. Later, angiosperms appeared and insects flourished. The flowers of angiosperms have a perianth, which is further divided into a calyx and a corolla (the perianth and corolla are collectively called petals). The petals are no longer green, but more conspicuous yellow, white or other colors. The shapes are also larger, some have nectaries that secrete honey, and some emit fragrance, which become insect-pollinated flowers. "Bees compete with pollinators and butterflies to share the fragrance," and insects complete the task of pollination and fertilization for flowers.

Insects have a special habit of collecting nectar for pollination, that is, they often only visit the flowers of the same plant. This habit helps ensure cross-pollination between plants of the same species and the reproduction of offspring. This fixes the characteristics of the species, including flower color. We can imagine that if there was a plant with reddish flowers, the red flowers are more likely to attract the attention of insects and have more opportunities for pollination. After countless generations of selection, over a long period of time, insects will give This plant creates a single, prominent, bright red flower. Insects participate in the role of natural selection, resulting in various plants and different flower colors.

Why are the flowers so red? In the end, it is down to artificial selection. Natural selection proceeds slowly and takes a long time to show its effects. Artificial selection greatly speeds up its process, enabling significant results to be achieved in a shorter period of time. For example, peony, a wild original species created by natural selection over hundreds of millions of years, has single-petaled flowers and only one color, pink. Through artificial cultivation, just in the middle of the Northern Song Dynasty (11th century), within a few decades, multi-leaf, thousand-leaf (double-petal), Louzi (flower center protruding), parallel peduncle, etc. were created from single petals. Various postures; pink creates various beautiful colors such as deep red, flesh red, purple, ink, yellow, white, etc. Another example is the dahlia, which is native to Mexico and has only eight red petals. The history of artificial cultivation is only two to three hundred years, but there are thousands of varieties with different shapes and colors. Another example is the poppy poppy. After cultivation, it has various colors of red, yellow, orange, and white, but it has never appeared blue. At the end of the last century, Purbank, a famous American horticultural breeder, discovered a poppy with a layer of smoke on its petals, and specially cultivated it. By the beginning of this century, various shades of blue poppies had been developed, which are known as flowers. Gardening adds new varieties.

. The flowers of snapdragon are usually closed, but when one of its favorite bees flies over, the flowers will open immediately. When other small insects come "knocking" on the door, it ignores it. The flower of the night grass only opens its smiling face at night, specifically waiting for a small moth that hides in a dark place during the day to fly to help it carry pollen.

(2) Read "Not Seeking Deep Explanation" and answer the questions that follow. (13 points)

Not seeking a thorough explanation

① Most people often think that it is bad not to seek a thorough explanation of any problem. Not really. Although we do not need to advocate the attitude of not seeking deeper understanding, there is no sufficient reason to blindly oppose the attitude of not seeking deeper understanding.

②The phrase "not seeking a deeper understanding" was first said by Tao Yuanming. He wrote in the short article "The Biography of Mr. Wu Liu": "If you are good at reading, you don't ask for a deep understanding; every time you have an understanding, you happily forget to eat." People often only grasp the first sentence he said, and forget the last sentence he said. In a word, therefore, I am very dissatisfied with Tao Yuanming's reading attitude. Why bother?

③ It should be admitted that it is very important to develop the habit of reading well. If you really get into the book, and the more you read, the more interested you will become, and you will naturally gradually understand the principles in the book. If you want to fully understand all books at once, especially important classics, no one except the arrogant would dare to be so confident. The key to reading is all about understanding. Regarding this point, Tao Yuanming especially has unique insights. Therefore, whenever he really understood something, he would be so happy that he would even forget to eat.

④ In this way, Tao Yuanming advocated that reading requires understanding, and it is not easy to truly understand, so he had to say that he did not ask for a deep understanding. It can be seen that the meaning of the four words "not asking for deep understanding" has two levels: one is to advise scholars not to be arrogant and conceited, thinking that they can understand a book after reading it, but in fact they may not truly understand the true meaning of the book. It's better to honestly admit that you just don't ask for a deeper explanation. Second, don't be too stubborn and chew on words, but be thorough and understand the general idea. Both meanings are very important and worth our understanding.

⑤ In this regard, the ancients did have many successful experiences. This is how Zhuge Liang studied. According to Wang Can's "Notes on Heroes", Zhuge Liang, Xu Shu, Shi Guangyuan, Meng Gongwei and others studied together on a study tour. "The three of them focused on mastery, while Liang alone observed the rough outline." It seems that Zhuge Liang is indeed much smarter than Xu Shu and others, because people who observe his schematic tend to have broader knowledge and a more comprehensive understanding of problems.

⑥Of course, this does not mean that reading can be careless or careless. Appreciating the rough outline also requires serious reading, but you just don't pick out every word or sentence, don't lose the big because of the small, and don't give up the whole for a certain part.

⑦ Lu Xiangshan, an acting scholar of the Song Dynasty, said in a quotation: "Read at a level, let go of the unknown areas, don't be too slow." This also means not to lose the big for the small. The so-called "let go of the unknown" does not mean to let go of the ununderstood parts and ignore them, but to let them go for the time being, and you will still understand their meaning in the end.

⑧ Experience has proven that there are many books that you still don’t understand after reading them once or twice, but you will understand them after reading them three or four times; or there are many things you don’t understand after reading the beginning of a book, and you will suddenly understand them after reading them. Some books could not be understood yesterday, but they will be understood after reading them some days later; some books seemed to have been understood, but in fact they were not understood very much. Only after gaining some practical knowledge did they really understand their meaning. Therefore, important books must be read frequently and repeatedly.

10． Among the punctuated words in the following sentences, the one that will have the least impact on the accuracy of the sentence expression after deletion is (). (2 points)

A. Most people often think that B. It is not good to not seek a thorough solution to any problem

C. In fact, this is not necessarily the case D. There is also no good reason to blindly oppose the attitude of not seeking deeper explanations

11. In paragraph 4, the author believes that "not seeking to understand the meaning of the four characters" reflects a good reading method. What is it? (3 points)

12. Which sentence in "Heroes' Notes" and Lu Xiangshan's quotations are basically consistent with the reading concept of "not seeking deeper explanations"? (Answer in the original text) (2 points)

"Heroes' Notes": □□□□ (4 words)

Lu Xiangshan’s quotations: □□□□□□ (6 words)

(3) Read "Little Village?" Me", answer the following questions. (11 points)

A small village? Me

When I got up, the white mist was still covering the whole village, and the village was still snoring gently.

The fog has not cleared yet, and I have already sat down by the small river behind the village, praying for the fish to bite the hook. Today I want to deliver fish soup to Grandpa Yusheng. What happened the day before yesterday has been lingering in my mind. I can't touch it because it hurts like a needle when I touch it.

I haven’t been back to my hometown for two years. The houses are still the same and the roads are still the same. The only change is that there are casinos everywhere, filled with smoke and noisy people. Through the smoke, you can see the faces of men, women, old and children. Numb and bloodshot eyes were shining like silver coins... On the stone steps in front of the village, Grandpa Xiuwu sat. I said hello to him, and his twitching mouth twisted for a long time before a hoarse sound came out of his throat...

I heard that the old single Yusheng Grandpa in the village was about to die, and the village doctor It is asserted that in the past few days, he has developed advanced liver and ascites, and his belly has become swollen like a big watermelon. It was rumored that the disease was contagious, and the villagers stayed away from him. I heard that he once went to the bathroom of Tianming's house, and Tianming's family didn't dare to go in to urinate for three days. Even his two nephews in the village didn't bother to look at him, as if if they looked at him, germs would creep towards him.

I probably know that hepatic ascites is just the late stage of cirrhosis, and cirrhosis is not contagious. I originally planned to go see him, but after procrastinating for two days, this impulse gradually cooled down. ...

Yesterday afternoon, I was standing in front of his courtyard with a bag of snow pears, but I didn’t have the courage to knock on the somewhat shabby door for a long time. My heart was beating very fast. The pear suddenly became very heavy, and then became very light.

After a long time after knocking on the door, the door creaked open, revealing the old face of Grandpa Yusheng. A particularly gentle smile appeared on his dry mouth. I have never seen such sad eyes.

There are tall weeds growing in the deserted yard, and there is a light musty smell. At this time, a swallow chirped and flew in, landed on a new bird's nest under the eaves, and kept making crisp chirping sounds. I sat down with Grandpa Yusheng on the wooden pillar in the courtyard. He could only be said to be half leaning on a high wooden pillar, and his stomach made it impossible for him to sit down.

I talked to him about fish. He used to love catching fish. When he talks about fish, his dull eyes light up with a strange look.

"The first fishhook I got when I was a kid was given by you."

"You were so happy that day that you sat by the pond for a long time and caught ten fish. There are many small crucian carp seeds, let your mother make soup for you..."

I have been sitting on the pebble beach by the river for a long time, but the float is still floating in the water. The voice of Grandpa Yusheng who said, "You can't even get a bowl of fish soup now" is still lingering in my heart.

Shrubs more than one meter high grow on both sides of the river, making the middle of the river look a little dark. I moved my butt uneasily, sometimes looking at the gray sky, sometimes at the float.

Through the trees, I heard voices on the road. "Do you think that boy Yu Fei is stupid? He went to Yu Sheng's house yesterday afternoon! Fortunately, he is still a college student, so he is not afraid of getting sick?" It's Uncle Quan!

I heard Xiao Liushu smile again: "Why isn't Mr. Yu Sheng dead? If he dies, I won't be afraid anymore. I can still have a few meals and drinks..."

They The voice gradually became fainter. The float was still sitting idle on the water, so I changed the bait again.

Not long after, the float suddenly trembled slightly, and then was gently dragged toward the center of the river. I suddenly lifted the fishing rod and pulled out a carp weighing half a kilogram.

On the way back to the village, I picked up a few green onions and wild garlic. Listening to the sound of fish jumping in the basket, I imagined the taste of this bowl of fish soup.

When I say this, you should have guessed that Grandpa Yusheng did not drink the bowl of soup.

When I returned to the village, he was carried out of the village, and a ferocious lock was hung on his door.

When Grandpa Yusheng’s grave had not yet been photographed, and the people who buried him were joking in front of the grave without a tombstone, I rushed to the grave with the cooked fish soup, and the joking people immediately Be silent.

I know that in their eyes now I am a confused person. I opened the lid of the crock and fed the fish soup to Huangtu one by one.

Because I am the only college student in the village.

Reference answers for the second volume of the second volume of Jiangsu Education Edition Chinese for Grade 8):

1 Zhan Xi Xiao Wan 2 (1) Withered vines and old trees and faint crows (2) Wei Wu De Xin ( 3) The long smoke sets and the lonely city is closed (4) The swallow has not yet come back and has no plan to return (5) I want to go up to the blue sky to embrace the bright moon and raise a cup to relieve my sorrow and make it worse (6) The moss marks on the steps are green, and the grass is green into the curtain 3 B 4, ( 1) There is no unified answer. Themes with clear emotions and clear meanings, such as Praise of Birds (Hymn), Spirits in Birds, Birds in My Heart, etc., can be used. (2) There is no unified answer. Example ① Eagle: In the vast sky, there is a stage for its fight everywhere. Heroic, heroic and passionate are its soaring melody. It was built to fly. Example ② Haiyan: Like black lightning, it flies proudly over the sea with rolling dark clouds and huge waves. It is a prophet of victory and a brave fighter.

Proportion of rural population (just guess what you want). 6 examples: This is the result of insects participating in natural selection, and it is also a significant achievement of artificial selection. As long as it's right. 7. The process is slow; the flower color, shape (or variety) is single. 8 It can be seen from the statistical table that white, yellow and red flowers have the most flowers, while orange, brown and black flowers have the least. Or the number of white, yellow and red flowers far exceeds the number of orange, brown and black flowers; or the colors of the flowers open from white, yellow to black, and the number gradually decreases. White, yellow, and red (with green leaves) are more conspicuous, easier to attract the attention of insects, and have more opportunities for pollination, resulting in an increase in the number of flowers in these colors. On the contrary, orange, brown and black flowers are not eye-catching, are not easy to attract the attention of insects, and have fewer opportunities for pollination, so there are fewer flower varieties in these colors. 9Why are the flowers so red? It is also the result of flowers choosing insects. 10 C 11 Don’t be too stubborn and stick to words, but be thorough and understand the general idea. 12 "Hero's Notes": Look at the rough outline. Lu Xiangshan's quotations: Let it go if you don't know. 13 cannot. Because it: ① makes the proof more rigorous, ② makes the viewpoint more dialectical. ③ Argument from the negative side. 14①Read it several times before you understand it (you don’t understand after reading it for two times, but you understand it after reading it for three or four times).

②You won’t understand until you read it later (you won’t understand it until you read it later). ③It will take some time to understand (I couldn’t understand it before, but it will take some time to understand). ④You can only understand after you have practical knowledge (I didn’t understand it before, but you will understand after you have practical knowledge). 15 What "I" saw and heard when I returned to my hometown and the story of "I" making soup for Grandpa Yusheng. 16 Two years ago, the small village was a pure, harmonious and beautiful scene full of human touch; two years later, it was a depressed scene of squalor, indifference and indifference between people. 17 As in the beginning, "The houses are still those houses, and the roads are still the same. The only change is that everywhere you go there are casinos, filled with smoke and noisy people. Through the smoke, the faces of men, women, old and young are numb, but silver coins flash out of their bloodshot eyes. "Like a light..." wrote about the "dirty" and "cold" scene of his hometown two years later, hinting at the tragic experience of Grandpa Yusheng, and at the same time reflecting the sadness in "my" heart. Another example is "There were tall weeds growing in the deserted yard, and there was a light musty smell. At this time, a swallow flew in with a chirp, landed on a new bird's nest under the eaves, and kept making crisp sounds. "The chirping sound." describes the living environment of Grandpa Yusheng, and also hints at the inevitable fate of Grandpa Yusheng. 18 Agree. In their eyes, I was indeed confused, but in fact "I" was an intellectual young man who was sober, aware, and understood the true feelings. (As long as the meaning is correct) 19 The author uses the road as a metaphor to express "my" hope and yearning for the beautiful future of my hometown, and is full of firm belief in changing the ignorance, indifference and backwardness of my hometown (small village).
