Until now. A new machine-learning system of artificial intelligence(AI) can successfully predict the risk of a cardiac arrest (心搏骤停) using timing and weather data，according to a new study published in the journal Heart. The study found that the out-of-hospital risk of cardiac arrest was highest on Sundays，Mondays，during sharp drops in temperature during or between days，and on public holidays. The new findings could serve as an early warning system，lowering the risk of deadly episodes and raising survival chances，in addition to improving emergency medical services’ ability to prepare for serious situations.This is significant because out-of-hospital cardiac arrests are common globally，and are generally linked to low survival rates. To deepen the research，the scientists evaluated the capacity of machine learning to anticipate daily out-of-hospital cardiac arrests via timing，as in the year，season，day of the week，hour of day，and daily weather，like snowfall，temperature，wind speed，and atmospheric pressure readings.Between 2005 and 2013，1，299，784 cases happened，and machine learning was implemented for 525，374 cases using timing data，weather，or both for a training dataset.These results were then contrasted with 135，678 cases that happened between 2014 and 2015，to examine the model’s capacity for accuracy of anticipating the statistical number of daily cardiac arrests in other years. “This predictive model may be useful for preventing out-of-hospital cardiac arrests，” said the researchers.However，it’s critically important to note that this study does not promise a way to predict when people will really die from a cardiac arrest.As a leading cause of death，the new machine-learning AI merely predicts when the risk of having a heart attack is high. [语篇解读]　本文是一篇说明文。文章主要介绍了一种新的人工智能机器学习系统，它可以利用时间和天气等数据成功预测心搏骤停的风险。 1．What’s paragraph 3 mainly about? A．The seriousness of cardiac arrests. B．The power of artificial intelligence. C．The great significance of the findings. D．The symptoms of cardiac arrests. 答案：C 2 3 1 4 解析：段落大意题。第三段前两句描述了心搏骤停发生风险最高的时间段，然后阐述了新发现可以对心搏骤停作出预警，降低发病风险，提高生存机会等，意义重大，故本段主要讲了新发现的重大意义。选项C与文义相符，故选C。 2 3 1 4 2．What does the underlined word “implemented” mean in paragraph 4? A．Created.　　　　　　　　 B．Applied. C．Suspended. D．Updated. 答案：B 2 3 1 4 解析：词义猜测题。根据画线词前后语境可推知，在2005年至2013年间，机器学习系统通过数据等信息预测了525 374例心搏骤停的发生，所以画线词此处含义是“应用，实施”。故选B。 2 3 1 4 3．What’s the author’s attitude to the warning system? A．Critical. B．Negative. C．Doubtful. D．Objective. 答案：D 2 3 1 4 解析：观点态度题。根据最后一段内容可推知，对于这个人工智能预警系统，作者仅仅是做出了客观性的评价。故选D。 2 3 1 4 4．What is the main purpose of the text? A．To state the potential risks of heart attacks. B．To stress the importance of conducting researches. C．To introduce a breakthrough of a disease prediction. D．To point out the shortcomings of modern technology. 答案：C 2 3 1 4 解析：写作目的题。根据第二段内容及全文可知，本文的写作目的是介绍一种可以用来预测心搏骤停风险的人工智能机器学习系统。选项C与文义相符，故选C。 2 3 1 4 Ⅴ.语法填空 [语篇解读]　本文是一篇说明文。文章介绍了在DAWN Café里试运营的机器人，它们配备了摄像头和扬声器，可以被远程控制，使残疾人或不出家门的人可以在家工作。 Some people fear that robots will replace humans in the workplace, but at DAWN Café that couldn’t be further from the truth.These robots，1.___________ (equip) with cameras and speakers，can 2.___________ (control) from a distance, which allows people with disabilities to work. The employees control the robots from home, using the Internet.For example, if someone can’t move or speak, they can use advanced software to type 3.____________ wide range of messages with their 4.____________ (eye).Once the robots receive those messages，they are communicated to the customers. The employees also have access 5.____________ a live video feed (实时视频馈送) so they can see what is going on. 1．答案：equipped 解析：考查非谓语动词。分析句子结构可知，空处在句中作定语，句子主语these robots与equip之间为逻辑上的动宾关系，所以此处要用过去分词形式。故填equipped。 2．答案：be controlled 解析：考查动词的语态。分析可知，空处在句中作谓语，句子主语these robots与control之间为逻辑上的动宾关系，所以要用被动语态。结合空前情态动词can可知，此处填be controlled。 3．答案：a 解析：考查冠词。固定短语a wide range of意为“各种各样的”。故填a。 4．答案：eyes 解析：考查名词的单复数。eye“眼睛”为可数名词，结合设空前的their可知，此处要用复数形式。故填eyes。 5．答案：to 解析：考查介词。固定短语have access to意为“有……的权利/机会”。故填to。 “There are many people 6.____________ are eager to work even though they can’t move.If they have an opportunity 7.____________ (get) a job, it gives them confidence，” said the inventor. 6．答案：who/that 解析：考查定语从句。分析可知，“6. are eager to work even though they can’t move”为定语从句，设空处在从句中作主语，先行词为people，所以此处用关系代词who或that。故填who/that。 7．答案：to get 解析：考查非谓语动词。固定短语have an opportunity to do sth.意为“有做……的机会”。故填to get。 While DAWN Café was 8.____________ (original) only open for a trial run，9.____________ (it) goal is to found a permanent location soon. After all, they brought in over 900 customers in less than two weeks! We hope this 10.____________ (amaze) idea will be popular all around the world. 8．答案：originally 解析：考查词性转换。open“开放的”为形容词，所以前面要用副词来修饰。original“最初的”为形容词，其副词形式为originally，故填originally。 9．答案：its 解析：考查代词。goal“目标”为可数名词，所以前面要用形容词来修饰。it的形容词性物主代词为its，故填its。 10．答案：amazing 解析：考查词性转换。idea“想法”为可数名词，其前要用形容词修饰。故填amazing。 $$
