In a small, new study, researchers taught 27 middle－age women (ages 40 to 65) how to perform 32 facial exercises, which included simple actions such as smiling in the cheeks. After this training, the participants performed these exercises at home for 30 minutes a day, every day for eight weeks. On the ninth week of the study, the participants reduced the frequency of their 30－minute exercise routine to every other day (three to four days a week), and continued the exercise for 20 weeks. 课时作业(三) 9 The participants also had their photos taken at the beginning and end of the study, and several doctors rated these photos using a standard method for assessing the appearance of aging in the face and neck. The raters, who didn't know which photos were taken before and which photos were taken after the exercises, also estimated the age of the person in the photo. After 20 weeks, the participants had better ratings for the fullness of their cheeks, on average, compared with their ratings at the start of the study. In other words, their cheeks looked fuller after their 20－week facial exercise. This change in cheek fullness also made the participants look younger: Raters estimated that the participants looked nearly three years younger after the exercises, compared with before. 课时作业(三) 10 However, the findings are preliminary and should be confirmed with a larger study, the researchers said. And many questions remain about exactly which exercises are beneficial and who might benefit from them. “The study involved middle－age, mainly white women, who stayed in the study for 20 weeks, so it's not known whether the effects seen in the study would apply to men, or to people of other ages or races. It's also not clear how long people need to perform the exercises in order to see benefits，” lead study author Dr Murad Alam said. 篇章导读：本文是一篇说明文。文章介绍了一项新研究。研究表明，定期练习面部肌肉运动，即“面部瑜伽”，可能使人看起来更年轻。 课时作业(三) 11 1．What did the researchers first do in the study? A．They trained the participants. B．They divided the participants into groups. C．They took photos of the participants. D．They checked the faces of the participants. 解析：细节理解题。根据第二段中的“In a small, new study ... After this training”可知，研究人员首先对参与者进行面部动作的训练。故选A。 课时作业(三) 12 2．What was the participants' specific change according to the study? A．They looked healthier. B．They got fuller facial outline. C．They became interested in yoga. D．They got to smile more frequently. 解析：细节理解题。根据第四段中的“After 20 weeks ... 20－week facial exercise.”可知，经过20周的训练后，参与者的脸颊看起来更饱满，即她们的面部轮廓更丰满。故选B。 课时作业(三) 13 3．What does the underlined word “confirmed” in the last paragraph mean? A．Proved. B．Questioned. C．Challenged. D．Affected. 解析：词义猜测题。根据画线词前文“However, the findings are preliminary”以及后文“And many questions ... benefit from them.”可知，当前的研究只是初步的发现，还有许多问题有待解决，需要进一步证明，即画线词意为“证明”。故选A。 课时作业(三) 14 4．What can be inferred from Dr Murad Alam's words? A．More facial exercises will be performed. B．Middle－aged women will not be included. C．Men participants will appear in later studies. D．20 weeks is enough to test if an exercise works. 解析：推理判断题。根据最后一段中Dr Murad Alam (穆拉德·阿拉姆)的话“The study involved ... in order to see benefits”可知，该研究的主要参与对象是中年女性，而这远远不够，由此可推知，为了证明研究的可信度，男性参与者将在之后的研究中出现。故选C。 课时作业(三) 15 B Some people look forward to getting braces (牙箍) on their teeth, thinking they look cool. Other people avoid visiting the orthodontist (正齿医生). But anyone who benefits from the orthodontist's trade today should be thankful for the progress this science has made over the centuries. 课时作业(三) 16 Remains of crooked (弯曲的) human teeth date back tens of thousands of years. Greek and Roman texts describing the treatment of irregular teeth by the application of pressure date back as far as the fifth century B．C. Archaeological evidence indicates even earlier use of orthodontic appliances, including man­made objects found in considerable burial (埋葬的) sites in ancient Italy. Another early attempt at braces may have been discovered on Egyptian mummies with recognizable metal bands around their teeth. Thus, from at least 1，000 BC, it was known that teeth move in response to pressure. 课时作业(三) 17 Techniques for correcting dental (牙齿的) irregularities did not advance much until the eighteenth century. French dentists led the way to building orthodontic practice on scientific foundations. The greatest contribution came from Pierre Fauchard. In 1728, Fauchard published the first general study of dentistry. In it, he described the process of straightening. He made smooth a crooked tooth to create space around it. Then he repositioned the tooth using a tool called a “pelican”. And he bound it to its neighbors and let it set. French and English dentists improved on Fauchard's work through the eighteenth century. Patients of Fauchard's treatment may have been grateful when the work was completed. While many of them faced the treatment with fear and cried during the procedures, there were many Frenchmen who flooded to Fauchard to improve their looks with dental work. 课时作业(三) 18 Pioneering European orthodontists introduced new techniques and instruments in the nineteenth century. By midcentury, American dentists began to take the lead in research and invention. Electricity changed the operating room completely, and the proper medicine made surgery less painful. John Farrar developed guidelines for using tools to move teeth by applying force on a regular basis. The twentieth century saw improvement in the materials and methods of orthodontics. But the basic principles of the science were developed during the days of Fauchard. 篇章导读：本文是一篇说明文。文章主要介绍了口腔正畸学的发展历程。 课时作业(三) 19 5．What's the public's attitude toward Fauchard's treatment? A．Objective. B．Fearful. C．Unconcerned. D．Positive. 解析：推理判断题。根据第三段中的“While many of them ... their looks with dental work.(虽然他们中的许多人面对治疗感到恐惧，并在手术过程中大哭，但仍有许多法国人涌向Fauchard (福沙尔)，希望通过牙科手术改善他们的容貌。)”可推知，公众对Fauchard的治疗持肯定态度。故选D。 课时作业(三) 20 6．What was Americans' contribution to orthodontics? A．Americans relieved the pain from the treatment. B．Americans repositioned the tooth using a “pelican”． C．Americans introduced new techniques and instruments. D．Americans published the first general study of dentistry. 解析：细节理解题。根据第四段中的“By midcentury, American dentists ... the proper medicine made surgery less painful.(到本世纪中叶，美国牙医开始在研究和发明方面处于领先地位。电彻底改变了手术室，适当的药物使手术不那么痛苦。)”可知，美国人对牙齿正畸的贡献是：减轻了治疗带来的痛苦。故选A。 课时作业(三) 21 7．What can be the suitable title for the text? A．Straight History of Orthodontics B．Advanced Techniques in Orthodontics C．Thanks for the Progress in Orthodontics D．Establishment of Professional Orthodontics 解析：标题判断题。通读全文并结合首段中的“But anyone who benefits ... over the centuries.(但是，今天任何受益于正畸牙医行业的人都应该感谢这门科学在过去几个世纪里所取得的进步。)”以及最后一段中的“The twentieth century ... methods of orthodontics.(二十世纪，正畸的材料和方法都有了改进。)”可知，本文主要讲了口腔正畸学的发展历程。A项(口腔正畸简史)最适合作为文章标题。故选A。 课时作业(三) 22 8．Where can the passage be found? A．In an interview report. B．In a private diary. C．In a medical journal. D．In a graduation essay. 解析：推理判断题。通读全文可知，本文主要介绍了口腔正畸学的发展历程。由此可推知，这篇文章可能出现在医学杂志上。故选C。 课时作业(三) 23 Ⅴ　语法填空 Screen time for children and teens is a battlefront that many parents know well.
