单选题 We may all like to consider ourselves free spirits. But a study of the traces left by 50,000 cellphone users over three months has conclusively proved that the truth is otherwise.
"We are all in one way or another boring," says Alhert-László Barabási at the Center for Complex Network Research at Northeastern University in Boston, who co-wrote the study. "Spontaneous individuals are largely absent from the population."
Barabási and colleagues used three months' worth of data from a cellphone network to track the cellphone towers each person's phone connected to each hour of the day, revealing their approximate location. They conclude that regardless of whether a person typically remains close to home or roams far and wide, their movements are theoretically predictable as much as 93 per cent of the time.
Surprisingly, the cellphone data showed that individuals'movements were more or less as predictable at week ends as on weekdays, suggesting that routine is rooted in human nature rather than being an effect of work patterns.
The cellphone records were processed to identify the most visited locations for each user. Then the probability of finding a given user at his or her most visited locations at each hour through the day was calculated.
People were to be found in their most visited location for any given hour 70 per cent of the time. Not surprisingly, the figure increased at night, and decreased at lunchtime and in the early evening, when most people were returning home from work.
The team analysed the randomness(随意的) of people's traces to show it was theoretically possible to predict the average person's whereabouts as much as 93 per cent of the time.
"Say your routine movement is from home to the coffee shop to work: if you are at home and then go to the coffee shop it's easy for me to predict that you are going to work," says co-author Nicholas Blumm.
This predictability was not much affected by differences in age, gender, language spoken or whether a person lived in a rural or urban setting.

单选题 The "spontaneous individuals" are most probably people who______.

【正确答案】 C

【答案解析】[解析] 第1段是Barabási的研究结果，第2段是对第1段的进一步解释，将这两段的内容相比可知，spontaneous individuals应该与第1段开头提到的free spirits同义，即spontaneous individuals最可能指生活上无拘无束的人，因此，本题应选C。
[点睛] 虽然本文一开头就提到了cellphone，但本文的研究并非针对人们在生活中对cellphone的态度，因此，A和B都没有原文依据。对比第2段第1句提到的关于boring的内容和spontaneous individuals所在的句子的内容。可发现这两句提到的spontaneous应与boring相反，因此，D不正确。

单选题 A phone user's location is shown by______.

【正确答案】 A

【答案解析】[解析] 原文该句中，cellphone towers是关键词，句中的to track…及其后的内容表明Barabási是通过记录手机信号在各个时段连接到哪个信号塔，从而推测手机用户的大概位置，本题应选A。
[点睛] 在原句中，each person's phone connected to是修饰先行词cellphone towers的定语从句，先行词cellphone towers在从句中为Connected to的宾语，cellphone network不是connected to的宾语，因此，B是对原文结构的错误理解；C中的how often和D中的content都缺乏原文依据。

单选题 What did the cellphone data show about "routine"?

【正确答案】 D

【答案解析】[解析] 第4段末尾的routine is rooted in human nature表明routine“植根于”human nature，这也可以理解为routine来源于human nature，由此可见，D的说法与原文相符，故为本题答案。
[点睛] 原文并没有提及routine会不会反过来对work pattern和human nature产生影响，因此，A和B描述的关系不存在。第4段末尾的rather than…表明routine受human nature的影响，而不受work patterns的影响，因此，C不正确。

单选题 According to the sixth paragraph, a person is more likely to ______ at night than in the early evening.

【正确答案】 C

【答案解析】[解析] 第6段第2句中的the figure increased at night表明晚上超过70%的情况下，都可在一个人最常去的地方找到他，C表达了相同的内容，故为本题答案。
[点睛] 本题稍具干扰性的是A和D，第6段末尾，作者提到home一词只是为了说明在午饭时间和傍晚，人们通常会在下班回家途中，因此，在这一时段想要在一个人平时最常去的地方找到他，可能性低于70%，但该句并没有表明home；就是人们晚上“最常去的”的地力，因此，A和D不正确。

单选题 What is the passage mainly about?

【正确答案】 B

【答案解析】[解析] 第1段首先提出人们普遍的想法：We may all like to consider ourselves flee spirits。在第2段至第4段，作者通过分析手机数据说明我们并没有自己想象的那么随心所欲，我们的行为是可预测的，最后几段进一步说明这种可预测性，因此，全文的主要内容应该是“可预测性”，由此可见，本题应选B。
[点睛] 尽管文中多次提到cellphone，但研究人员只是借助手机数据研究人们的日常行为是否可以预测，手机本身并不是研究的对象，因此，A和C均不正确；原文并没有提及可以通过哪些因素去预测人们的日常行为．因此．D的factors缺乏原文依据。
