The four must-read environmental books are sure to attract the greenest bookworms. Braiding Sweetgrass Braiding Sweetgrass by Robin Wall Kimmer looks at the relationship between humans and the land. Kimmer ties lessons she learned to Western society’s view of plants and aims to tell the importance of plants and animals. The book also explores the lessons we may learn from plants and animals and how they relate to certain stories. Braiding Sweetgrass won the 2014 Sigurd F. Olson Nature Writing Award. The End of Nature The End of Nature was published in 1989. Its author, Bill Mckibben, describes the relationship between nature and humans. It expresses the thought that nature was previously independent of humans but now has been affected by them in every way. The book tells the ideas of nature and the value it has lost. Silent Spring Written by Rachel Carson, Silent Spring has been described as a landmark work of environmental writing and is praised for bringing the environment al movement into the public’s focus. The book stresses the effects of pesticides (杀虫剂) on the environment. The book eventually led to a change in the pesticide law of the US. The Sixth Extinction The Sixth Extinction by Elizabeth Kolbert describes previous mass extinction events and connects them to many extinctions presently taking place. Kolbert studies the relationships humans have with the environment and finds that we are in the midst of the sixth mass extinction caused by humans. The Sixth Extinction won the 2015 Pulitzer Prize for General Non-Fiction. 1. Whose book focuses on nature’s lost value due to human activities? A. Robin Wall Kimmer’s. B. Rachel Carson’s. C. Bill Mckibben’s. D. Elizabeth Kolbert’s. 2. Why is Silent Spring so important? A. It has reduced the use of land. B. It has affected a law in the US. C. It has changed people’s view of plants. D. It has prevented nature from being independent. 3. What do Braiding Sweetgrass and The Sixth Extinction have in common? A. They won a prize. B. They focus on the lessons we learn. C. They are about mass extinction events. D. They view nature to be independent of humans. B Ma Xiaohui, a famous Chinese erhu performer, held a concert in New York City earlier this month. The concert began with an overture (序曲) titled Legend of the Silk Road, and then came the theme song from the movie Crouching Tiger, Hidden Dragon, which beautifully celebrated the classic dialogue between erhu and cello (大提琴). “This beautiful and inspiring concert wonderfully mixed classical, Chinese and cross-cultural themes. It was a feast for the ears and souls. The performance was full of creativity centered around Ma’s mastery of the instrument.” says artist Ranjit Bhatnagar. “As a guitarist, I had the honor to perform with Ma,” says Tim Kelly. “Her powerful, moving melodies (旋律) inspired both me and the audience. It seems that in her hands, the instrument can touch the heart of every listener.” Influenced by the lively atmosphere, the 2023 World Madam Global Overall Champion, Sepideh Behboudi, danced to the music many times with his partner Ethan Rimes and other audience. Ma says music is an international language, and national musical instruments have their own unique characteristics. Using them as messengers, they can spread melodies of truth, goodness and beauty to all. She expresses a hope that the world can feel the charm of Chinese culture, the spiritual beauty of Chinese art and the warmth of the erhu to touch hearts. According to Ma, her tour was not limited to just music, but also brought a healing experience to the audience. Ma with the Middle Tennessee State University Symphony performed the erhu concerto (协奏曲) Tianshan Shepherdess, as if bringing the audience to the foot of the Tianshan Mountains to see the blue sky, white clouds and the carefree shepherd. 4. Who performed music with Ma Xiaohui? A. Sepideh Behboudi. B. Ethan Rimes. C. Tim Kelly. D. Ranjit Bhatnagar. 5. What does the underlined word “they” in paragraph 5refer to? A. The audience. B. Unique characteristics. C. International languages. D. National musical instruments. 6. What does Ma expect of her music tour? A. It can make her rich. B. It can help her with further study. C. It can spread Chinese culture and art. D. It can give her a chance to be a master. 7. Which words can best describe Ma’s Tianshan Shepherdess? A. Serious and tiring. B. Natural and relaxing. C. Traditional and loud. D. Fast and sad. C A Japanese candy company has been making national news headlines for its idea to produce gummy candy (软糖) that tastes like an “imaginary fruit” called Kiraspika. Last year was a great one for gummy candy producers, and the market continued to expand throughout 2023, with fruit-flavored (水果味的) gummies being the most popular. There are plenty of fruit flavors to choose from, but companies are still limited to the fruits that can be found in our world. However, what if someone started making candy that tastes like imaginary fruits? That was the strange idea that a Japanese sweets maker recently came up with. Two months ago, the company created a new type of gummy candy that tastes like fruit “Kiraspika no Mi”, an imaginary fruit with an original flavor, design, and even a story. According to the story, the star-shaped Kiraspika only grows in the mountainous area of Blue Knife, where temperatures drop to —50℃ in winter. It is very difficult to get. Everything about Kiraspika was invented in the fruit lab where its flavor experts mixed various existing flavors to create a totally original one that tastes like nothing you’ve ever eaten. According to its designers, the Kiraspika-flavored gummy candy has a unique sweetness mixed with a kind of sourness (酸味), but many of those who have tried it have their own description of the taste. To some, the Kiraspika flavor can be compared to that of an energy drink, while others say it tastes a bit like a spicy apple. It is the mystery of the flavor and the personal explanations that make this product liked by many people. 8. What does the underlined word “expand” in paragraph 2 mean? A. Disappear. B. Shorten. C. Struggle. D. Grow. 9. What is a feature of Kiraspika? A. It can’t be found in real life. B. It grows on the plain. C. It can be planted easily. D. It needs high temperatures. 10. What makes the new type of gummy candy popular? A. Its shape. B. Its taste. C. Its origin. D. Its designer. 11. Where does this text probably come from? A. A news report. B. A health magazine. C. A biology book. D. An old story. D Leif Richardson, who is a conservation biologist, and I are out with the goal of piecing together a picture of where wild bees live, and which species are in trouble in the home range of a native bee called Crotch’s bumble bee (大黄蜂). That bee is protected by the state law, and it’s one of the many species under survey. Our journey began at the foot of a mountain in Leo Carrillo State Park. It was a cloudy morning. We set off for a short hike, armed with bee nets and a cooler to cool any bees we would catch. It’s a harmless way to temporarily calm the bees, and to allow for more careful study and photos. Just a minute later, as Richardson walked into a meadow (草地), I heard him scream, followed by a snake! He stood there frozen for a moment before backing away towards the path, and then the snake went away. We were a little more careful with the possibilities then, as we prepared to catch our first bees. They were not hard to find—I could hear them buzzing everywhere, and soon Richardson said it was time for me to catch one. He told me to pinch (捏住) the tip of my net and held it upright, while slowly lowering it over a flower where our bumble bee was standing. As soon as the bee realized what was going on, it buzzed furiously inside my net, and then slowly climbed up the net towards the tip right where my finger was. It all seemed like a high possibility to get stung (被蜇). But Richardson assured me I would be fine. He had some advice for holding it. “You’re going to pinch harder than you think you need to, but not so hard that you hurt the bee.” As my fingertips got closer to the bee, it felt like I could hear it buzzing louder and louder. Richardson performed this whole process in seconds. For me, on the other hand, it was a nervous act of much concentration. But it paid off—and soon, I got my very first bee! 12. What did Richardson come across on the way? A. A sudden rain. B. A snake. C. A bee net. D. A cooler. 13. What is paragraph 5mainly about? A. The process of bee-catching. B. The present situation of bumble bees. C. The challenge of finding a bumble bee. D. The purpose of studying bumble bees. 14. What can we know about Richardson’s bee catching? A. He failed. B. He got stung. C. He was nervous. D. He was professional. 15. What is the best title for the text? A. A Love of Nature B. A New Law for Bumble Bee C. An Outing for Bumble Bee D.

For the next six months, Mr. Thompson and Lily would go for a run every day after school. They started with short distances, gradually increasing the length and intensity of their runs. In the beginning, Lily struggled to keep up, but as time went by, she found herself becoming more and more engaged in this practice with Mr. Thompson. As Lily continued her daily runs, something remarkable started to happen. Lily’s once imitable personality slowly began to disappear, and she apologized to her parents for her former rudeness. Her grades remained consistently high with a changed lifestyle. Seeing Lily’s change, Mr. Thompson recommended her to give a speech to her classmates. In her speech, Lily expressed her gratitude to Mr. Thompson who helped her get rid of stress and build a good relationship with her parents. She explained that academic success was just one aspect of the identity and that physical and mental well-being were equally crucial. She said engaging in sports and exercise not only improved her overall health but also enhanced her ability to handle pressure. Through her own change, she encouraged her classmates to join her for runs, advocating the integration of sports into their lives. 1～5BACBC 6～10 ABCAB 11～15ABCBA 16～20 CABAC 第1页/共1页 学科网（北京）股份有限公司 $
