Ⅰ.阅读理解 语篇解读　这是一篇说明文。文章主要说明了人们现在可以依靠可访问的大数据，做出更好的决定。 We can use this big data to help determine the best course to chart. Researchers have found algorithms can be much better than people at making difficult decisions.The power of data analysis has been proved in the sports and business worlds，too.As made famous by the book and movie Moneyball，baseball teams found that algorithms were better than managers at picking strategies. But stats have had surprisingly little impact on our personal lives. One major problem is that good data about life’s biggest personal questions has been difficult to gain.Consider this question：what makes people happy？Some have revealed the activities that provide far more enjoyment than most of us would have guessed，such as exercising，going to a museum and gardening.Then there are the things that give us less pleasure than we might assume，such as playing video games，watching TV and browsing the Internet.Another way to be happier is moving house.They found that when people moved from an unhappy city to a happier place，their overall mood improved. There are early days of the data revolution in personal decision-making.A study of tens of millions of children has found the places that increase their future earnings most.Another shows certain cities can improve one’s life expectancy.I am not claiming that we can completely base our lifestyle choices on algorithms，though we might get to that point in the future.I am claiming instead that we can all dramatically improve our decision-making by consulting evidence from millions of people who faced dilemmas similar to ours via big data. 1.How can people make better decisions now? A.By doing plenty of interviews. B.By relying on accessible big data. C.By using common sense of life. D.By following others’ life behavior. √ 细节理解题。根据第一段内容可知，人们现在可以依靠可访问的大数据，做出更好的决定。故选B。 解析 2.Why is the movie Moneyball mentioned in paragraph 2? A.To suggest managers handle their players. B.To inform data can improve players’ skills. C.To show baseball is popular in sports world. D.To prove algorithms can make better decisions. √ 推理判断题。由第二段最后一句可推知，这里提到电影《点球成金》是为了证明算法可以做出更好的决策。故选D。 解析 3.What makes people happier than we guess according to paragraph 3? A.Visiting a museum. B.Surfing the Internet. C.Playing video games. D.Moving to a bigger city. √ 细节理解题。根据第三段中的“Some have revealed the activities that provide far more enjoyment than most of us would have guessed，such as exercising，going to a museum and gardening.”可知，参观博物馆让人们比我们猜测的更幸福。故选A。 解析 4.What does the author conclude in the end? A.The big data can increase our future earnings. B.The big data can prolong our life expectancy. C.We can improve decision-making via big data. D.We can develop our lifestyle in different ways. √ 推理判断题。根据最后一段最后一句可推知，最后的结论是我们可以通过大数据来改善决策。故选C。 解析 B Eating chocolate at least once a week could stave off a heart attack，according to new research.Chocolate is packed with plant chemicals that weaken inflammation(炎症) and help blood flow，explained scientists. 语篇解读　本文是一篇说明文。新的研究表明，适量食用巧克力有助于减轻炎症，促进血液流动，有利于我们的健康。 Lead author Dr Chayakrit Krittanawong said，“Our study suggests chocolate helps keep the heart’s blood vessels healthy.” It collected data from six trials that examined the link over the past five decades.A total of 336,289 people reported their intake.Those who ate chocolate more than once a week reduced their risk of coronary artery(冠状动脉) disease by eight percent.This was compared to peers who ate it less than once a week. Chocolate is known to produce the same chemical in the brain as falling in love.But evidence is growing that its reputation as a “guilty pleasure” is wrong.Dr Krittanawong said，“Chocolate contains heart healthy nutrients such as flavonoids，methylxanthines，polyphenols and stearic acid which may reduce inflammation.” Known medically as HDL(high-density lipoprotein)(高密度脂蛋白)，it helps to rid LDL(low-density lipoprotein) out of the body.When this collects，it causes vessels and arteries to become blocked up.It can stop blood flow to the heart or brain，causing a heart attack or stroke.Dr Krittanawong said，“In the past，clinical studies have shown chocolate is beneficial for blood pressure.” Dark chocolate has long been known to have health benefits，but recent research has suggested milk chocolate may also provide valuable nutrients to the heart.Dr Krittanawong pointed out his study did not investigate whether any particular type of chocolate is more beneficial or if there is an ideal portion size.He said，“Chocolate appears promising for the prevention of coronary artery disease.But more research is needed to show how much and what kind of chocolate could be recommended.” While it’s not clear how much is perfect，Dr Krittanawong warned people against overeating.He said，“Moderate amounts of chocolate seem to protect coronary arteries but it’s likely that large quantities do not.” 5.What does paragraph 2 mainly talk about? A.The result of the study. B.The process of the study. C.The participants of the study. D.The intention of the study. √ 段落大意题。根据第二段中的“Our study suggests chocolate helps keep the heart’s blood vessels healthy.”和最后两句“Those who ate chocolate more than once a week reduced their risk of coronary artery(冠状动脉) disease by eight percent.This was compared to peers who ate it less than once a week.”可知，本段主要是介绍Krittanawong博士的研究结果。故选A。 解析 6.Which of the following can probably prevent blood flow? A.A heart attack. B.A stroke. C.High-density lipoprotein. D.Low-density lipoprotein. √ 细节理解题。根据第四段前三句可知，当低密度脂蛋白聚集的时候，它会造成动脉血管堵塞，从而阻碍通往心脏或大脑的血液流通，最终造成心脏病发作或中风。故选D。 解析 7.What does the recent study tell us? A.Chocolate is good for blood pressure. B.Dark chocolate is beneficial to health. C.Milk chocolate may also benefit the heart. D.Chocolate contains special plant chemicals. √ 细节理解题。根据第五段首句中的“but recent research has suggested milk chocolate may also provide valuable nutrients to the heart”可知，牛奶巧克力对心脏可能也有好处。故选C。 解析 8.What’s Dr Krittanawong’s attitude toward chocolate’s preventing coronary artery disease? A.Indifferent. B.Hopeful. C.Negative. D.Uncertain. √ 推理判断题。根据第五段中的“Chocolate appears promising for the prevention of coronary artery disease.”可知，Krittanawong博士对于巧克力预防冠状动脉疾病的作用还是充满信心的。故选B。 解析 It all began when I moved to Dallas in the fourth grade.I 1 that I was behind in my reading at Saint Michael’s School. 1.A.declared B.assumed C.recommended D.noticed Ⅱ.完形填空 语篇解读　本文是一篇记叙文。文章讲述了作者在小时候被确诊患有阅读障碍，通过他人的帮助及自己的决心作者最终克服了这一挑战，作者长大后以志愿者的身份重新回到医院，来帮助这里的病人，以回报自己曾经受过的帮助。 √ 由下句可知，作者是在大声阅读时注意到自己在阅读方面有困难的，B选项assume“假设”，不符合句意； A、C与句意无关，故选D。 解析 Reading out loud，I had difficulty with half the 2 .My teacher，Mrs Agnew，said my reading comprehension and ability to 3 words were at a lower level than other fourth graders.She suggested that I be tested for dyslexia(阅读障碍). 2.A.sentences B.lectures C.Dictionaries D.chances 3.A.choose B.exchange C.pronounce D.write √ √ 2.由下句中的“reading comprehension”可知，作者是在读句子上有困难，故选A。 3.该空对应前文“Reading out loud”，说明是发音的能力，故选C。 解析 The test made me feel uncomfortable，and I was 4 to answer the questions，in fear of facing the 5 . 4.A.motivated B.scared C.confused D.disappointed 5.A.threat B.risk C.trick D.failure √ √ 4.由前文“The test made me feel uncomfortable”以及后文“in fear of”可知，作者害怕回答问题。故选B。 5.由前文可知，作者知道自己在理解句子和阅读的能力方面有问题，所以不敢做这个测试，害怕失败，故选D。 解析 The test results showed that I had developmental dyslexia.At first I felt discouraged by this diagnosis(诊断)， 6 eventually，I became determined to 7 my disability.I got tutors and speech therapy. 6.A.but B.so C.or D.unless 7.A.deny B.lose C.overcome D.hide √ √ 6.由上下文“I felt discouraged”“I became determined”可知此处应表示转折，故选A。 7.由后文“I had finally overcome my learning disability.”可知，此处表示作者下定决心克服自己的阅读障碍。故选C。 解析 I would read difficult books，hoping to 8 the confidence I had in myself. 8.A.shake B.share C.express D.increase √ 句意：我会读一些难懂的书，希望能增强我对自己的信心。结合句意和选项可知，D项符合题意。 解析 I had finally overcome my learning disability.But even though I had conquered(征服) one of the biggest 9 in my life，I still felt like something was missing. 9.A.challenges B.secrets C.decisions D.mistakes √ 由全文可知，作者的阅读障碍对作者来说一个挑战，其他选项均不符合句意，故选A。 解析 The missing link was 10 when I walked down the halls of the hospital as a 11 ，the same hospital where I had once stayed，nervous and confused.Because I felt so lucky to have got so much help from this facility，I wanted to 12 by helping patients here. 10.A.mentioned B.filled C.recommended D.assessed 11.A.relative B.visitor C.volunteer D.patient 12.A.turn away B.cut in C.hold on D.give back √ √ √ 10.句意：当我作为志愿者走在医院的大厅中时，我缺失的一环被填补上了。结合句意和选项可知，B项符合句意。 11.由前文可知，作者克服了阅读障碍，所以不再是patient，再由后文“helping patients here”以及作者为小女孩读书可知，作者应是以志愿者的身份重回医院，故选C。 12.结合上文可知，此处表示作者曾经从这个机构中获得了很多帮助，所以现在也想通过帮助其他病人来回报他人。故选D。 解析 One day a little girl in a wheelchair asked me to read a book to her.I read the book very 13 so that she could understand the story.When I left，the girl thanked me for reading to her. 13.A.properly B.sincerely C.slowly D.softly √ so that表承接，作者为了能让这个小女孩听懂，所以应是读的很慢，故选C。 解析 Eight years ago I would have 14 to read a book to this little girl，but now I am 15 .I had overcome my disability and was helping others to overcome theirs. 14.A.dared B.hesitated C.attempted D.happened 15.A.confident B.independent C.careful D.grateful √ √ 14.由关键词“Eight years ago”可知，那时作者还有阅读障碍，所以对给小女孩读书会感到犹豫，故选B。 15.由but可知前后句意相反，前半句说曾经的作者会对这个举动感到犹豫，所以后半句应该表示作者现在不再害怕、犹豫，同时confident也与第二段的confidence相呼应，故选A。 解析 返 回 本课结束 $
