The “igus：bike” will also help relieve the world’s plastic pollution problems.The company says a single adult bike gives new life to about 35 pounds of single-use plastic that would otherwise block our landfills or waterways.For example，the first prototypes were made of material from old fishing nets.Currently,90% of the “igus：bike” is made using plastic.Igus believes future versions will be made entirely from plastic. The plastic bikes are expected to come to market soon.An adult model，made entirely from recycled plastic，will cost about $1,430.A slightly cheaper version made using new plastic is also in the works.Igus also plans on sharing its technology with other bicycle manufacturers.“We want to enable the bicycle industry to produce plastic bikes，” says Blasé. 语篇解读　这是一篇说明文。文章介绍Igus公司为实现可持续性的发展推出了世界上第一辆由再生塑料制成的自行车。 8．Which statement is true about Igus? A．It is devoted to recycling plastic waste. B．It developed popular bikes in Germany. C．It follows the model of a traditional linear economy. D．It appeals to companies to invest in the bicycle industry. 答案　A 解析　细节理解题。根据第一段中“To help this transformation，Igus...has been developing and investing in the work of recycling plastics for many years.”可知，Igus公司致力于回收利用塑料。故选A。 9．What highlights the “igus：bike” according to paragraph 2? A．It is safer to ride. B．It will not rust rapidly. C．It is easier to maintain. D．It consumes less energy to produce. 答案　C 解析　细节理解题。根据第二段最后三句可知，igus：bike无需维护，不会生锈；不需要润滑油来减少零件之间的摩擦；不吸收沙、灰尘或污垢，几秒钟就能清洗干净。所以它的亮点是很容易维护。故选C。 10．What does paragraph 3 mainly tell us about the “igus：bike”？ A．Its huge market. B．Its complex design. C．Its multiple versions. D．Its environmental value. 答案　D 解析　段落大意题。根据第三段前两句可知，本段主要讲述了igus：bike在保护环境方面的重要意义。故选D。 11．What is the purpose of the text? A．To introduce a newly invented plastic bicycle. B．To stress the importance of technological innovation. C．To raise people’s awareness of environmental protection. D．To provide some advice on how to produce a new kind of bike. 答案　A 解析　写作意图题。根据第一段最后两句可知，第一段引出igus：bike，后文介绍了igus：bike的优点和对环境的重要意义，以及什么时候上市和价格。由此推知，本文旨在介绍一种新型的环保的再生塑料制成的自行车。故选A。 D Tomatoes are common in daily life.Cathie Martin，a British scientist，has been working on developing purple tomatoes for years.Though the color is unusual，now this special kind of tomato has very high levels of antioxidants(抗氧化剂)． Antioxidants，also known as AOS，are found naturally in plants like blueberries and red cabbage.Scientists believe AOS may help prevent heart disease and help fight against diseases like diabetes.But tomatoes naturally only have a small amount of AOS in them.Martin wanted to see if she could create tomatoes with lots of AOS by changing the DNA of a tomato plant. A plant developed from specially created DNA is known as a GMO.Martin added two genes(基因) from a plant called snapdragon.Soon her plants were producing small purple tomatoes with lots of AOS.Even better，the tomatoes remained fresh almost twice as long as normal tomatoes.Martin and other scientists further tested the tomatoes on mice that were likely to get cancer.The mice that were fed the purple tomatoes lived about 30% longer than those fed normal tomatoes.Though that’s good news，experiments on mice don’t always predict what effects on humans will be like.We need to see more experiments about it. GMOs were first allowed in America in the late 1990s.But GMO products weren’t popular with customers.Many people were scared by the idea that the foods weren’t natural or safe.There’re still questions about the effects of GMO crops on the environment.However，scientists deny these claims. Even so，many people have concerns about them.Because of these concerns，most GMO products created over the last 20 years have focused on helping farmers rather than attracting customers. Anyway，on September 7,2022，the US approved the purple tomatoes，which is the first time it has approved a GMO plant designed to target human health. 语篇解读　本文属于说明文。一种新的紫色番茄在美国获得批准种植和销售。科学家通过改变这种番茄的DNA，增加了它们的抗氧化剂含量，使这种番茄可以保存更久，并可能有助于人们的健康。 12．What makes purple tomatoes really special? A．Their proper size. B．Their pleasant color. C．Their medical value. D．Their delicious flavor. 答案　C 解析　细节理解题。根据第一段末句以及第二段第二句可知，紫色番茄中抗氧化剂含量高，抗氧化剂能够有助于预防心脏病和对抗糖尿病等疾病。故紫色番茄的特殊之处在于它的医用价值。故选C。 13．What’s the author’s attitude to the test on the mice? A．Favorable. B．Doubtful. C．Concerned. D．Opposed. 答案　B 解析　观点态度题。根据第三段最后两句可知，作者认为在老鼠身上进行的实验并不总是能预测对人类的影响是怎样的。我们需要看到更多关于它的实验。故作者目前对此实验心存怀疑。故选B。 14．What does the underlined word “so” in paragraph 5 refer to? A．The environment affects GMO foods. B．The customers do not like GMO foods. C．Scientists think GMO products are safe. D．GMO products are used to help farmers. 答案　C 解析　词义猜测题。第四段提到科学家们否认转基因食品不安全的说法。Even so意为“即便如此”，同时下文说许多人担心这些食品的安全，由此可推知画线词so指代的是前文的科学家们对转基因食物负面说法的否定，即科学家认为转基因产品是安全的。故选C。 15．What’s the suitable title for the text? A．Different DNA Can Benefit Plant Growth B．Tomatoes with Changed DNA Are Approved C．Scientists Are Changing DNA of Tomatoes D．Human Health Depends on Changed DNA 答案　B 解析　标题归纳题。通读全文可知，文章主要讲了英国科学家通过改变番茄植株的DNA培育出了一种含有大量抗氧化剂的紫色番茄并且这种番茄在美国最终获得了批准种植和销售。B项“转基因西红柿被批准上市”适合作文章标题，故选B。 Ⅱ.七选五(共5小题；每小题2.5分，满分12.5分) 阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。选项中有两项为多余选项。 (2023·安徽芜湖高二期中) Ways to Have a Productive Wednesday Monday and Tuesday have already come and gone，and it’s officially the middle of the workweek.Congratulations on making it halfway through! Here’s how to make your Wednesday go as smoothly as possible.Before you know it，Friday will already be knocking on your door. Prioritize(优先) the difficult assignments. 1 Writer and essayist Nicolas Cole writes about what unproductive people do，including “accidentally” canceling “their hardest tasks”．“Unproductive people find every reason in the world to prioritize making another to-do list over digging into their hardest tasks.Productive people do the opposite，” Cole writes. Don’t be a computer zombie(僵尸)，but head outside for a walk.While letting your eyes glaze over as you struggle through the day can be a tempting option，you’ll probably need to take some time away from your desk to truly focus. 2 Hands off the phone! More time scrolling through social media feeds(讯息) on your phone means less time crossing things off your to-do list.Try hiding your phone somewhere that isn’t in plain view as you work at your desk. 3 Also turn off certain announcements so you have fewer opportunities for distraction. Hit a roadblock？Think of yourself as someone else. 4 Put some space in between you and your problems to help decrease your anxiety.If that doesn’t work for you，imagine that your friend is in the situation instead. 5 Whether you love your job or are just getting by，work shouldn’t be your everything.Revisit that page-turner you stopped reading a while back，spend time with family or friends，or get back in touch with your hobby at a class after work. A．It might just be out of sight，out of mind. B．It can create a relaxing Wednesday routine. C．Do something to enjoy life outside of work. D．If you work，you have a sense of completeness. E．So go outside for a quick walk and a breath of fresh air. F．Don’t put them off，for you won’t be able to bury them forever. G．Science says that thinking of yourself in the third person can help you prevent stress. 1．答案　F 解析　上文“Prioritize(优先) the difficult assignments.”说明优先处理困难的任务。F项“不要拖延，因为你无法永远不做它们。”强调的也是优先处理困难任务。F选项中的“them”指的是上文中的difficult assignments。故选F。 2．答案　E 解析　上文建议出去走走，不要长时间坐在电脑前。因为花些时间放松有助于提高专注力。选项E“所以出去散散步，呼吸一下新鲜空气”与上文意思一致，为上文内容的总结。故选E。 3．答案　A 解析　上文建议在工作时把手机藏在一个不容易看到的地方。下文同样是减少分心的方法。选项A“也许只是眼不见，心不念”承上启下，符合语境。故选A。 4．答案　G 解析　根据上文“Think of yourself as someone else.”可推断，空格处内容与把自己想象成别人相关。选项G“科学表明，以第三人称思考自己可以帮助你避免压力”与上文内容意思一致，为对上文内容的具体解释。故选G。 5．答案　C 解析　该空为段落小标题，应总结该段内容。该段下文讲的是工作不应该是你的一切，你应该去做点其他事情。选项C“做一些工作之外的事情来享受生活”与下文意思一致，并总结该段内容。故选C。 学科网（北京）股份有限公司 $$
