Question

                 C ★★★★★

    Over the past decade,there have been many scientific studies on the digital (數(shù)字的) activity of people,such as making mobile calls,texting,e-mailing,and posting on social media. Nearly all human behavior leaves a digital footprint. Therefore,scientists can use such digital activity as a way to track human activity. For example,they can study differences between cultures in sleep patterns,work schedules,and spare time activities.

    Researchers from Finland and Denmark use a completely new approach to study digital rhythms (規(guī)律) .Previous studies focused on general patterns across large numbers of people. However,this time researchers focus. on pronounced,long-term differences in rhythm between inid?viduals. They show that people tend to have their personal rhythm of digital activity. It is stable like a personal signature 。(簽名)

    “Each individual follows their own daily rhythm ,” says Talayeh,who led the research. “In almost every case,the patterns differ strongly from the average behavior,for example by increased calling frequency during mornings,mid-days,or evenings ,” says Talayeh. What drives these individual differences is not yet clear. Geographical and cultural differences clearly play a role. “There could also be an effect of (生理學) .We see this research as the first step to understand how activity patterns are related to other people's characteristics,such as personality and mobility behavior,” say Talayeh.

    This finding could also have medical use. Digital rhythms could be monitored for patients with mental health problems. Sudden changes in patients’digital rhythms could be a sign that treatment may be necessary. “Combining this research with Big Data may also bring new ways of research in sleep studies ,” concludes Talayeh.

9. What do scientists use the digital activity of people to do?

   A. To make their research easier.

   B. To know about people's behavior.

   C. To aid the development of social media.

   D. To reduce people's dependence on mobile phones.

10. Which of the following can best describe digital rhythms?

   A. Natural but casual.

   B. Personal and fixed.

   C. Different but unclear.

   D. Changeable and mysterious.

11. According to Talayeh,digital rhythms .

   A. have nothing to do with personality

   B. have a great effect on everyday habits 

   C. may have something to do with culture   

    D. can help ?ie development of physiology 

12. What is the use of digital rhythms in the medical field?

   A. They can help avoid patients’ sleep problems.

   B. They will change the ways doctors do their work,

   C. They could free people of mental problems.

   D. They may tell whether a patient is well.

Answer 1

9.B 10.B 11.C 12.D

C篇人們在使用電子產(chǎn)品方面有固定的規(guī)律，這 種規(guī)律可以在很多方面得以應用。

9.B. 細節(jié)理解題。根據(jù)第一段中的scientists can use such digital activity as a way to frack human activity in genera可知，科學家們可以利 用人們使用電子產(chǎn)品方面的規(guī)律研究人們在行 為方面的特點。

10.B. 推斷理解題。根據(jù)第二段中的Ueyshow that people tend to have the? personal rhythm of digital activity. It is stable like a personal signature可知，人們使用電子產(chǎn)品方面的規(guī)律具有個性和穩(wěn)定性。

11.C. 細節(jié)理解題。根據(jù)第三段中的What drives these individual differences is not yet clear. Geographical and cultural differences clearly play a role可知，使用電子產(chǎn)品的規(guī)律與文化有一定關系。

12.D. 細節(jié)理解題。根據(jù)最后一段中的Sudden changes in patients’ digital rhythms could be a sign that treatment may be necessary 可知，病人 使用電子產(chǎn)品的規(guī)律能反應病人的病情狀況。
