There are plenty of low hills that look like waves and have many different 43 (colour), just like a rainbow! If you climb up to the top and see the hills from above, you 44 (find) rainbows painted on the ground. Of course, you’d better take 45 raincoat with you because the weather often changes 46 (sudden) during the climb. You may wonder how these colourful hills were developed. Millions of years ago, this area was under a lake. Over time, rivers were bringing sand 47 stones. These were left in layers (层) on the bottom of the lake. Some layers were red, some were yellow, and the others turned purple or white. Later, the climate 48 (become) much colder and drier, so that the lake dried up. Then, something special happened! The underground land began 49 (rise) up and push against each other. The layers of sandstone were lifted higher and higher. Through years of wind, sun, and rain, they formed the colourful hills we see today. The best time to visit the geopark is from June to September.

Maybe you will say this could only happen in some 51 (children) stories. In fact, plants are not always silent. So far, a recent study 52 (find) plants shout when they are in need of water or having their stems cut. “Even in a quiet field, there are 53 (actual) some sounds that carry information (信息). However, the pitch (音高) is too high for people 54 (hear),” said a teacher from Tel Aviv University. The researchers used microphones to record some tomato plants and found that stressed plants send out 55 (many) sounds than unstressed plants. “When tomatoes are not stressed at all, they are very quiet.” The teacher said that they also developed a machine to tell the differences 56 thirsty plants and cut plants. The result shows that 57 the causes of stress change, they shout differently. After 58 team recorded many kinds of other plants, they found that many plants like corn, wheat and grape plants send out sounds when they are under stress, too. “There is a possibility that a lot of talk is happening,” Professor Hadany said. “Because other 59 (plant) may hear the call of the stressed plants.” Sound recordings of plants could bring humans lots of advantages especially (尤其) in farming. For example, people will make sure 60 corn is getting enough water or not, or where water is needed most. 【答案】 51．children’s 52．has found 53．actually 54．to hear 55．more 56．between 57．when/as 58．the 59．plants 60．whether 【导语】本文介绍了一项最新研究，揭示了植物在缺水或茎被切断时会发出声音信号，且不同压力下的植物发声存在差异，这一发现对农业领域具有重要意义。 51．句意：也许你会说这只会发生在一些儿童故事里。stories是名词，前面需要用名词所有格或形容词修饰；children的复数名词所有格形式为children’s，表示“儿童的”，符合“儿童故事”的语境。 52．句意：到目前为止，一项近期研究发现植物在缺水或茎被切断时会发出声音。时间状语So far是现在完成时的标志，主语a recent study是单数，用has，find的过去分词为found。 53．句意：实际上，即使在安静的田地里，也有一些声音传递着信息。此处需要副词修饰整个句子 there are...，actual的副词形式为actually，表示“实际上、事实上”。 54．句意：然而，音高太高，人类听不见。too...to do sth.是固定结构，表示“太……而不能做某事”，因此hear需变为不定式形式to hear。 55．句意：研究人员发现，受压力的植物比未受压力的植物发出的声音更多。句中出现 than，是比较级的标志；many的比较级为more，表示“更多的”。 56．句意：这位老师说，他们还研发了一种机器来区分缺水植物和被切断茎的植物。between…and…是固定搭配，意为“在……和……之间”，符合“区分两种植物”的语境，故填between。 57．句意：结果表明，随着压力的原因发生变化，植物发出的声音也不同。此处表示“当……时/随着……”，引导时间状语从句，用连词when或as均可。 58．句意：在该团队记录了多种其他植物之后，他们发现玉米、小麦和葡萄等植物在受到压力时也会发出声音。此处特指研究的那个团队，用定冠词the修饰team，表示特指。 59．句意：因为其他植物可能会听到受压力植物的信号。other后接可数名词复数，plant的复数形式为plants。 60．句意：例如，人们可以确定玉米是否得到了足够的水分，或者哪里最需要水。whether…or not 是固定搭配，意为“是否”，符合“确定玉米是否有足够水分”的语境。 $ 班级 姓名 学号 分数 Unit 5 Looking into nature 单元重点单词变形短语语法句型精练 （时间：60分钟，满分：100分） 单元知识点默写 一、重点单词词性转换 试卷第1页，共3页 试卷第1页，共3页 学科网（北京）股份有限公司 1. know → ________ (adj. 未知的) 2. north → ________ (adj. 北部的) 3. Africa → ________ (adj. 非洲的) 4. full → ________ (adv. 完全地；充分地) 5. write → ________ (n. 写作；著书) 6. true → ________ (adj. 真实的) 7. end → ________ (adj. 无数的；无限的) 8. soft → ________ (adv. 轻柔地；柔和地) 二、单词默写 1. ________ n. 恐龙 2. ________ n. 羽毛，翎 3. ________ adj. 羽毛覆盖的 4. ________ n. 蜥蜴 5. ________ n. 琥珀 6. ________ conj. 是否 7. ________ n. 物种 8. ________ n. 观点 9. ________ v. 解锁 10. ________ n. 发现，（调查、研究等的）结果 11. ________ n. 报纸 12. ________ n. 风格 13. ________ n. 方法，办法 14. ________ adj. 变得兴味盎然，生动起来 15. ________ n. 论点，论据 16. ________ n. 布告牌，公告牌 17. ________ n. 模型 18. ________ n. 行星 19. ________ v. 清除；清理 20. ________ v. 上载，上传 21. ________ n. 鲸 22. ________ adj. 很热的，滚热的 23. ________ n. 化学物质 24. ________ v. 起化学反应 25. ________ n. 国，国家 26. ________ n. 视力，视觉 27. ________ pron. 任何人 28. ________ n. 放大镜 29. ________ n. 财富 30. ________ n. 国家 31. ________ n. 奖品，奖赏 32. ________ adv. 几乎不 33. ________ v. 应在（某处） 34. ________ n. 孙女；外孙女 三、短语默写 1. ________ 揭开某事的秘密 2. ________ 属于 3. ________ 弄清楚；查明 4. ________ 上传到…… 5. ________ 起反应 6. ________ 与……有关 7. ________ 几乎不；简直不 8. ________ 看起来像 9. ________ 被……覆盖 10. ________ 轻柔地说/唱 单元知识点习题训练 1、 用括号内所给单词的适当形式填空(本大题共20小题，每小题1分，共20分) 1．Few people knew how many rare plants ________ (grow) in the local forest last year. 2．We need ________ (clear) the room before the guests arrive. 3．I can ________ (hard) believe my eyes when I see the amazing view. 4．The ________ (wealth) man donated all his money to the poor children. 5．This is a ________ (history) story that tells us about the life of ancient people. 6．The water is ________ (boil), so be careful not to get burned. 7．There are ________ (end) problems in our life, but we should face them bravely. 8．He was ________ (complete) shocked by the news that his team won the game. 9．The ________ (believe) that dinosaurs could fly has been proved by new research. 10．The flower in the amber ________ (prove) that the species existed 35 million years ago. 11．Wang Wencai ________ (carry) on with his research even after losing sight in one eye. 12．Amber is ________ (regard) as a window on the past by scientists. 13．Wang Wencai ________ (devote) his whole life to studying plants. 14．Could you please give me some ________ (piece) of paper? 15．There are many ________ (secret) in the ocean waiting for us to find. 16．Scientists are trying their best ________ (explore) nature. 17．It was a great ________ (achieve) for the young player. 18．It is such fine weather.

The underground land began 49 (rise) up and push against each other. The layers of sandstone were lifted higher and higher. Through years of wind, sun, and rain, they formed the colourful hills we see today. The best time to visit the geopark is from June to September. Mornings and evenings are much 50 (cool) than the hot afternoons. During these times, you can enjoy the wonderful sunrises and sunsets over the hills. Sunshine after a summer rain will make the colours even brighter and more beautiful. Do you believe a rose plant says, “I’m thirsty!” or a tree shouts, “My arms hurt? Maybe you will say this could only happen in some 51 (children) stories. In fact, plants are not always silent. So far, a recent study 52 (find) plants shout when they are in need of water or having their stems cut. “Even in a quiet field, there are 53 (actual) some sounds that carry information (信息). However, the pitch (音高) is too high for people 54 (hear),” said a teacher from Tel Aviv University. The researchers used microphones to record some tomato plants and found that stressed plants send out 55 (many) sounds than unstressed plants. “When tomatoes are not stressed at all, they are very quiet.” The teacher said that they also developed a machine to tell the differences 56 thirsty plants and cut plants. The result shows that 57 the causes of stress change, they shout differently. After 58 team recorded many kinds of other plants, they found that many plants like corn, wheat and grape plants send out sounds when they are under stress, too. “There is a possibility that a lot of talk is happening,” Professor Hadany said. “Because other 59 (plant) may hear the call of the stressed plants.” Sound recordings of plants could bring humans lots of advantages especially (尤其) in farming. For example, people will make sure 60 corn is getting enough water or not, or where water is needed most. $
