He has received invitations to walk at the some of the largest fashion weeks on the global stages.Lu has over 4 million followers on his Kuaishou account, where he posts videos under the name“Xiao Xianren”. Lu rose to fame chasing his passion for modelling while working as a restaurant waiter and a factory worker in Nanning, the capital of Guangxi. “I have had a supermodel dream since I was ten, while I was still in a primary school. I saw a fashion show on TV when I feel it was so cool to do that on the catwalk, ”said Lu. Since then, he practices the catwalk every day.Without any professional training, he learned catwalk from fashion show video. He turned everywhere into his runway, from a narrow passage to a deserted factory.“From clothing designing and making to filming and posting, these were extremely time-consuming but barely received feedback on line in the beginning. But I still enjoyed the process, ” said Lu. “The early dozens of videos I posted even didnt receive likes,” Lu recalled. But I believed what Ive done would be recognized by the world someday.” Lu insisted on posting his fashion works onto Kuaishou where he hoped to be seen by more people.Many laughed at Lus early works as they thought of him as a funny clown (小丑) wearing very strange costumes. Howerver, Lus insistence, coupled with Kuaishous powerful algorithms (演算法), enable Lu to be seen, which eventually helped him to enter mainstream fame.Lus big break came in August 2019 when Lus fans uploaded his videos from Kuaishou to YouTobe.

(陆因对模特的热爱而成名，他曾在广西省会南宁做过餐厅服务员和工厂工人。)”可知，陆开港成名前在工厂工作过。故选A。【6题详解】细节理解题。根据文章第五段“Many laughed at Lus early works as they thought of him as a funny clown(小丑) wearing very strange costumes. (许多人嘲笑陆开港的早期作品，认为他是一个穿着奇装异服的滑稽小丑。)”可知，陆开港的作品曾经被嘲笑过。故选A。【7题详解】词义猜测题。根据文章最后一段划线词后半句“more people became curious about Lu and his international career took off from there.

The prefix nano refers to a nanometer, which is one-billionth of a meter. How small is that exactly? A comma on a page of a book may be more than half a million nanometers wide.Researcher Ted Sargent, a leader in the field of nanotechnology, describes how using quantum (量子) dotsparticles that are a few nanometers in size will help diagnose a disease. The particles, Sargent explains, shine brightly when exposed to UV light and can be inserted into the body. They can also be programmed to bond only to a particular cancer cell. Doctors can then use a camera and look for the color1 ed particles, which will help them determine where cancer cells are growing in a persons body. Using this technology, it will be possible to detect cancer at a stage when there are perhaps only a thousand bad cells.Once a certain type of cancer is detected, nanotechnology will also improve the way it is treated. Nanoparticles will allow doctors to attack cancerous tumors (肿瘤) without disturbing healthy cells. Doctors can deliver cancer-killing drugs, carried via the nanoparticles, to the bad cells only or they can also destroy cancer cells identified by nanoparticles, using laser rays. Ultimately, technologies like this will allow doctors to deliver cancer treatment earlier, faster, and more thoroughly, with fewer side effects.Unfortunately, though nanoparticles have great medical potential, there are serious concerns that they could have negative environmental and health effects. In recent studies researchers found that half the human cells died after exposing lab-grown human cells to water containing large amounts of nanoparticles.Because nanotechnology is so potentially useful, many scientists dont think research into its many uses should be stopped; learning more about nanotechnology should remain a priority. Scientists do believe that governments should allocate more money for safety-related studiesto make sure that large concentrations of nanoparticles do not get into our food and water supplies and cause serious problems.8. What is this passage mainly about?A. The dangers and side effects of nanotechnology.B. The various ways of detecting different cancers.C. The development and application of nanotechnology.D. How nanotechnology can be used in medical science.9. Whats the size of a nanometer?A. The size of a comma.              B. One-billionth of a meter.C. A billion nanoparticles wide.              D. The same size as a quantum dot.10. Exposing human cells to large amounts of nanoparticles _.A. does not have any influences              B. may prevent many side effectsC. causes one second cells death              D. could cure a variety of cancers11. What can we infer from the last paragraph?A. Nanotechnology proved to be useless and the research should be ended.B. Scientists want to see research into nanotechnology continue with caution.C. Many scientists think that nanotechnology is too dangerous to be permitted.D. Nanotechnology is so useful that many governments are investing in research.【答案解析】 8. D    9. B    10. C    11. B【分析】本文是一篇说明文。文章介绍了纳米技术以及纳米技术在对抗癌症和在其他医学方面的应用。【8题详解】主旨大意题。根据第三段“Researcher Ted Sargent, a leader in the field of nanotechnology, describes how using quantum (量子) dotsparticles that are a few nanometers in size will help diagnose a disease.”（研究人员泰德·萨金特（Ted Sargent）是纳米技术领域的领军人物，他描述了如何使用几纳米大小的量子点粒子来帮助诊断疾病。）以及第四段“Once a certain type of cancer is detected, nanotechnology will also improve the way it is treated. Nanoparticles will allow doctors to attack cancerous tumors (肿瘤) without disturbing healthy cells. ”（一旦发现某种癌症，纳米技术也将改善其治疗方式。纳米颗粒可以让医生在不干扰健康细胞的情况下攻击癌细胞。）及全文可知，文章主要讲的是纳米技术在医学科学方面的作用。故选D。【9题详解】细节理解题。根据第二段“The main thing to know about nanotechnology is that its small really small. The prefix nano refers to a nanometer, which is one-billionth of a meter.”（关于纳米技术要知道的主要事情是它很小-非常小。前缀nano指的是纳米，是十亿分之一米。）可知，一纳米只有十亿分之一米。故选B.【10题详解】细节理解题。根据倒数第二段“In recent studies researchers found that half the human cells died after exposing lab-grown human cells to water containing large amounts of nanoparticles.”（在最近的研究中，研究人员发现，将实验室培养的人体细胞暴露在含有大量纳米颗粒的水中后，有一半的人体细胞死亡。）可知，会有一半的细胞死亡。故选C。【11题详解】推理判断题。根据最后一段“Because nanotechnology is so potentially useful, many scientists dont think research into its many uses should be stopped; learning more about nanotechnology should remain a priority. Scientists do believe that governments should allocate more money for safety-related studiesto make sure that large concentrations of nanoparticles do not get into our food and water supplies and cause serious problems.”（由于纳米技术具有巨大的潜在用途，许多科学家认为不应停止对其多种用途的研究；更多地了解纳米技术仍然是当务之急。科学家们确实认为，政府应该为安全相关的研究拨出更多的资金，以确保高浓度的纳米颗粒不会进入我们的食物和水供应，并造成严重的问题。）可知，虽然不应停止对纳米技术多种用途的研究，但也应该同时确保纳米颗粒不会造成严重的问题，所以我们可以推断出科学家们希望看到纳米技术的研究继续保持谨慎。故选B。DA new product from Microsoft Corporation can do just that for people who have trouble seeing.
