By age 8, children were more likely to log the highest amount of screen time if they had been in home­based children or were born to first­time mothers. 课时作业(四) “Our results indicate that screen habits begin early，” said Edwina Yeung, an investigator in National Institute of Child Health and Human Development (NICHD)．“This finding suggests that interventions (干涉) to reduce screen time could have a better chance of success if introduced early.” In the research, mothers of 4，000 children responded to questions on their kids' media habits when they were 12, 18, 24, 30, and 36 months of age. 课时作业(四) The American Academy of Pediatrics recommends avoiding digital media exposure for children under 18 months of age, introducing children 18 to 24 months of age to screen media slowly, and limiting screen time to an hour a day for children from 2 to 5 years of age. In the current study, researchers found that 87% of the children had screen time exceeding (超过) these recommendations. However, while screen time increased throughout toddlerhood, by age 7 and 8, screen time fell to under 1.5 hours per day. The researchers believe this decrease relates to time consumed by school­related activities. 课时作业(四) The study authors classified the children into two groups based on how much their average daily screen time increased from age 1 to age 3. The first group, 73% of the total had the lowest increase, from an average of nearly 51 minutes a day to nearly an hour and 47 minutes a day. The second group, 27% of the total, had the highest increase, from nearly 37 minutes of screen time a day to about 4 hours a day. Higher levels of parental education were associated with lower odds of inclusion in the second group. 篇章导读：本文是一篇说明文。文章介绍了不同年龄段的儿童平均使用屏幕时长，并提出及早采取干预措施，减少儿童使用屏幕的时间。 课时作业(四) 1.Who use mobile device longest according to the NIH's analysis? A．10­year­old born to first­time mothers. B．3­year­old children in low income families. C．8­year­old children in home­based childcare. D．1­year­old children with parents poorly educated. 解析：细节理解题。根据第一段最后一句“By age 8 ... to first­time mothers.”可知，到8岁时，如果他们是在家庭式托儿所的孩子，或者是初为人母的孩子，那么他们更有可能花最多的时间看屏幕。即家庭式托儿所的8岁儿童使用移动设备的时间最长。故选C。 课时作业(四) 2．What does the research suggest according to Edwina? A．Parents should stop their children using media. B．Parents should limit the use of digital media themselves. C．Parents should reduce their children's screen time earlier. D．Parents should avoid their children using digital media at infancy (婴儿期)． 解析：细节理解题。根据第二段中的“This finding suggests that ... if introduced early.(这一发现表明，如果及早采取干预措施，减少屏幕时间的成功率会更高。)”可知，Edwina Yeung(埃德温娜·杨)认为这项研究表明了家长应该尽早减少孩子的屏幕时间。故选C。 课时作业(四) 3．Why does children's screen time fall when they age 7 and 8? A．They are studying at school. B．They can control themselves. C．They are tired of using them. D．They are forbidden to use them. 解析：细节理解题。根据第四段最后两句可知，当孩子长到7岁和8岁时，屏幕时间下降到每天1.5小时以下。研究人员认为，这种减少与学校相关活动所消耗的时间有关。故选A。 课时作业(四) 4．Which of the following may be the best title? A．Keep Away from Media B．Screen Habits Begin Early C．Urgency of Parental Education D．Harm of Home­based Childcare 解析：标题判断题。通读全文可知，文章表明了儿童很早就接触屏幕了，由此可知，B项(屏幕习惯很早就开始了)最适合作为文章标题。故选B。 课时作业(四) B Technology is forever changing the way we get our news. Many people now get a lot of their news on electronic devices, instead of traditional media, such as newspapers, television or radio. Now, there is a new way we get the news: computer­created news readers. China's Xinhua launched (推出) the world's first AI news presenters with the Chinese search engine Sogou. The news readers created by machine learning technology are based on two real­life newsmen. One is able to present newscasts in English; the other, in Mandarin Chinese. 课时作业(四) One Xinhua's report said machine learning was used to examine video images and sounds of the two newsmen, which look and sound like real people. Some machine learning experts said the system showed off China's latest progress in voice recognition, text­to­speech technology and data analysis. But several experts suggested that the term AI does not correctly describe abilities of the robotic news readers. On social media, many Chinese noted that the AI presenters did not seem real. People blamed them for not being more lifelike. Others wondered about the effects robots might have on employment and workers. Some people argued that only low­level jobs requiring heavy labor will be easily replaced by robots. Others praised the technology as a way for companies to make money from low­cost labor machines. 课时作业(四) Some businesses have experimented with similar technology for possible use in news operations. Britain's BBC recently released a video that used machine learning to make it look like one of its news readers was speaking different languages. The London­based company that developed the system says its goal is to “remove the language barrier” for many different kinds of video across the Internet. 篇章导读：本文是一篇议论文。文章介绍了新华社推出的两个人工智能新闻节目主持人所引起的一些思考和争议。 课时作业(四) 5.What does the author intend to do in Paragraph 1? A．Introduce the topic of the text. B．Summarize the different opinions. C．Add some data about the AI presenters. D．Compare different ways of getting news. 解析：推理判断题。第一段首先说明科技永远在改变我们获取新闻的方式，最后一句“Now, there is a new way we get the news: computer­created news readers.”引出了本文的话题。故选A。 课时作业(四) 6．What is the machine learning technology used to do? A．To keep AI presenters from making any mistakes. B．To make AI presenters speak more fluently. C．To ensure images and sounds are like real persons. D．To bring newscasts up to date every hour. 解析：细节理解题。根据第三段中的“machine learning was used to ... which look and sound like real people”可知，这一技术用来检查视频图像和声音，以使图像和声音看起来或听起来就像真人一样。故选C。 课时作业(四) 7．What are some people worried about when AI presenters were launched? A．Robots will eventually replace human all over. B．Robots may threaten some people's employment. C．Robots may endanger most people's health. D．Robots will rule over the world in the end. 解析：细节理解题。根据第五段第三句“Others wondered about the effects robots might have on employment and workers.”可知，有些人担心机器人可能会给就业和劳动者带来影响，即他们担心机器人可能威胁到一些人的就业。故选B。 课时作业(四) 8．What can we learn from the last paragraph? A．BBC has removed the language barrier in newscasts. B．BBC's news readers can speak different languages. C．BBC shows interest in Xinhua's AI news presenters. D．BBC has done similar experiments as Xinhua does. 解析：推理判断题。根据最后一段中的“Some businesses have experimented ... was speaking different languages. (一些企业已经试验了类似的技术，以便在新闻业务中可能使用。英国的BBC最近发布的一段视频就是使用机器学习技术，使它看起来像是一名新闻播报员在讲不同的语言。)”可知，BBC也做过和新华社一样的实验。故选D。 课时作业(四) Ⅱ　语法填空 A Chinese dance drama has made its global debut (首映) on social media platforms abroad, __1__ (create) a new wave of discussion on the beauty of Chinese culture among art lovers from all over the world. “Li Bai”， a classic production by the China National Opera and Dance Drama Theatre, __2__ (strike) a chord (弦) with global audiences through the telling of a lifelong journey of the literary giant Li Bai so far.
