Before us stretched the unending sand dunes that marked the beginning of the Sahara. A small boy walked past with a group of noisy goats as I took a long look at the yellow 课后巩固 多维提能 1 2 3 8 roadside sign that told us we were entering a “fragile natural environment”．I made a resolution to respect and protect this unique landscape while I was here. We set off, our vehicle quietly running over the sand and small stones. It wasn't long before we were surrounded by enormous sand dunes towering above us on all sides. The wind was blowing grains of sand from the tops of the dunes, the sun was beating down hard and bright, and the sky was a deep shade of blue that I had never seen before. 课后巩固 多维提能 1 2 3 The wild beauty of the desert was about to reveal itself. There was not a plant to be seen. The desert appeared completely empty, which was calming and threatening at the same time. The colours of the dunes contrasted strikingly with the blue of the cloudless sky. 课后巩固 多维提能 1 2 3 3 July, Kenya A few days after our departure from the camp, our car was well and truly stuck in the mud. We were very near to our rest camp in Amboseli National Park located on the border of Kenya when my father, against my mother's advice, decided to drive through a large pool of water that stretched across the dirt road. Two tall slim local people were standing by the roadside watching us with amusement. They must have realized that we were totally 课后巩固 多维提能 1 2 3 11 helpless, for after a few moments, they wandered over and pushed us free. My father smiled weakly and we drove on as my mother and I waved from the car window. We found a parking space next to our hut, which was round and made from brick. We got out of the car, carrying our suitcases and boxes of food into the hut. I placed ham sandwiches, sausages and a bunch of bananas on a small wooden table. I returned to the car and fetched more possessions. It was then that I noticed a small 课后巩固 多维提能 1 2 3 grey monkey sitting on a tree a few metres away and eating a banana.“So cute，” I thought to myself, until I realized it was my banana that he was eating! He was looking at me intently as he enjoyed the final mouthful. I was sure he was saying, “Thank you.” “You're welcome，” I replied. 课后巩固 多维提能 1 2 3 1.What's the main idea of this passage?( ) A.The beautiful Sahara desert and animals of Africa.

According to the scientists from the University of Exeter, plants may keep communicating with each other through a secret “unseen” language. For their experiment, the scientists picked a cabbage plant that is known to send out a gas when its surface is cut. In order to get video evidence of the communication, they changed the cabbage gene by adding the luciferase （荧光素酶）, which is what makes fireflies （萤火虫） glow in the dark. 课后巩固 多维提能 1 2 3 4 5 6 7 8 When the changed cabbage plant was in full bloom, they cut a leaf off with a pair of scissors, and almost immediately, thanks to the luciferase, they could see the plant sending out “methyl jasmonate （茉莉酸甲酯）”. While this was a known fact, what was surprising was the fact that the minute this gas began to be released, the nearby cabbage plants seemed to detect some kind of danger and started to send out 课后巩固 多维提能 1 2 3 4 5 6 7 8 a gas that they normally have to keep enemies like caterpillars （毛虫） away. What the scientists are not sure is whether the plants are trying to warn the other leaves or the near plants of the danger—something that will require further research. However, the team, which is led by Professor Nick Smirnoff, is quite excited about the findings because this is the first time it has been proved that plants do not live a passive life, but actually move, sense and even communicate with each other. 课后巩固 多维提能 1 2 3 4 5 6 7 8 【解题导语】 本文是一篇说明文。文章介绍了科学家们发现植物之间可能在通过一种“看不见的”语言进行交流。 课后巩固 多维提能 1 2 3 4 5 6 7 8 21 1.What does the underlined word “they” in paragraph 1 refer to?( ) A.Gardeners. B.Plants. C.Scientists. D.Fireflies. 解析：代词指代题。根据指代关系和画线词所在句可推知,they指代上文中的“gardeners”。 √ 课后巩固 多维提能 1 2 3 4 5 6 7 8 22 2.Which of the following statements is NOT true of the passage when the plant sent out “methyl jasmonate”?( ) A.The nearby cabbage plants seemed to sense some kind of danger. B.The nearby cabbage plants started to send out a gas. C.The nearby cabbage plants tried to warn the near plants. D.The nearby cabbage plants communicated through a secret language. 解析：细节理解题。根据第五段中的“What the scientists are not sure...require further research.”可知，科学家们不确定这些植物是否在试图警告附近的植物。因此C项表述有误。 √ 课后巩固 多维提能 1 2 3 4 5 6 7 8 23 3.What can we learn from the experiment?( ) A.Plants don't live a passive life. B.Plants can feel pain when they are cut. C.Plants can warn the other leaves of danger. D.Plants can talk with each other. 解析：细节理解题。根据第五段中的“plants do not live a passive life...with each other”可知,植物不是被动地生活。 √ 课后巩固 多维提能 1 2 3 4 5 6 7 8 24 4.From which of the following is the passage probably taken?( ) A.A health magazine. B.A biology magazine. C.A medical research paper. D.A travel brochure. 解析：文章出处题。通读全文,尤其是第一段中的“According to the scientists...a secret ‘unseen’ language.”和最后一段中的“this is the first time...with each other”可知,文章介绍了科学家们发现植物之间可能在通过一种“看不见的”语言进行交流。由此可推知,本文很可能选自生物学杂志。 √ 课后巩固 多维提能 1 2 3 4 5 6 7 8 25 B （2025·西安蓝田期中）Biologists from the John Innes Centre in England discovered that plants have a biological process which divides their amount of stored energy by the length of the night. This solves the problem of how to portion out （分配） energy reserves during the night so that the plant can keep growing yet not risk burning off all its stored energy. 课后巩固 多维提能 1 2 3 4 5 6 7 8 26 While the sun shines, plants perform photosynthesis（光合作用）. In this process, the plants change sunlight, water and carbon dioxide into stored energy in the form of long chains of sugar, called starch （淀粉）. At night, the plants burn this stored starch to fuel continued growth. “The calculations are precise so that plants prevent starvation but also make the most efficient use of their food,” said study co-author Alison Smith. “If the starch store is used too fast, plantswill starve and stop growing during the night. If the store is used too slowly, some of it will be wasted.” 课后巩固 多维提能 1 2 3 4 5 6 7 8 The scientists studied the plant Arabidopsis, which is regarded as a model plant for experiments. To give the plants some math tests, the biologists let night arrive unexpectedly early or late for them. During one of the exams, they shut off the lights on the plants early that had been grown with twelve-hour days and nights. Putting them into darkness after only an eight-hour day meant they didn't have time to store as much starch as usual. And this forced the plants to adjust their normal nightly rhythm. 课后巩固 多维提能 1 2 3 4 5 6 7 8 Amazingly, even after this day length trick, the plants did very well in their exams and ended up with just five percent of starch left over at the end of the night. They had neither starved, nor stored starch that could have been used to fuel more growth. The authors suggested that similar biological calculators may explain how a migratory bird, the little stint, can make a five-thousand-kilometer journey to their summer habitat in the Arctic and arrive with enough fat reserves to survive only approximately half a day more, on average. The results of the study were published in eLife. 课后巩固 多维提能 1 2 3 4 5 6 7 8 【解题导语】 本文是一篇说明文。文章介绍了植物体内有类似生物计算器的控制系统来控制能源消耗。 课后巩固 多维提能 1 2 3 4 5 6 7 8 5.What can we learn from the passage?( ) A.Plants use little energy during the day. B.Plants usually stop growing at night. C.Plants waste a lot of energy at night. D.Plants store starch during the day. 解析：细节理解题。根据第二段中的“While the sun shines...called starch.”可知,植物在白天进行光合作用储存淀粉。 √ 课后巩固 多维提能 1 2 3 4 5 6 7 8 31 6.What did the scientists do when studying Arabidopsis?( ) A.They changed the plant's light conditions. B.They provided the plant with more starch. C.They tried to keep the plant's natural rhythm. D.They attached a biological calculator to the plant. 解析：细节理解题。根据第四段中的“To give the plants...early or late for them.”可知,为了研究拟南芥,科学家们改变了植物的光照条件。 √ 课后巩固 多维提能 1 2 3 4 5 6 7 8 32 7.How about the experimental plants when the morning arrived?( ) A.They nearly died of lack of food. B.They used most of their stored energy. C.They began to regulate their food store. D.They stored enough starch for the next day. 解析：细节理解题。根据第二段中的“At night, the plants burn this stored starch to fuel continued growth.”和第六段中的“Amazingly, even after this day...at the end of the night.”可知,当早晨到来时，实验植物使用了大部分储存的能量。 √ 课后巩固 多维提能 1 2 3 4 5 6 7 8 33 8.What can we learn about the little stint?( ) A.They may have a system to control energy consumption. B.They often die during their long and difficult journey. C.They leave the Arctic in summer every year. D.They are unable to calculate the distances. 解析：推理判断题。根据第一段和倒数第二段内容可知，植物有类似生物计算器的控制系统来控制能量消耗，类似的生物计算器可以解释小滨鹬,由此可推知,小滨鹬可能也有一个系统来控制能量消耗。 √ 课后巩固 多维提能 1 2 3 4 5 6 7 8 34 Ⅱ.完形填空 （2025·四川凉山州安宁河联盟期中）Many years ago, I had an unforgettable experience.
