Ⅰ.阅读理解

A

Your circle of friends may help you get a better reading  of your  overall  health  and wellness rather than just using wearable devices such as a Fitbit, according to researchers.

The study, published in the journal PLOS ONE, analyzed what the structure of social networks  says  about the  state  of health, happiness and stress.

“We were interested in the topology (拓扑学) of the social network—what my position within my social network predicts about my health and well­being，”said Nitesh V. Chawla, an educationalist at the University of Notre Dame in the US.

“What we found was that the social network  structure  provides  a  significant improvement in predictability of wellness states of an individual over just using the data obtained from wearables, like the number of steps or heart rates，” Chawla said.

For the study, participants wore a Fitbit to capture health behaviour data about walking, sleeping, heart rates and overall activity level. They also completed surveys and self­assessments of their stress, happiness and positivity.

Chawla and his team then analyzed the data with a machine learning model, alongside the association and characteristics of an individual's social network.

The study showed a strong correlation (关联) between social network structures, heart rates, the number of steps and level of activity.

Social network structure provided extraordinary improvement in predicting one's health and well­being in contrast to just looking at health behaviour data from the Fitbit alone.

For example, when social network structure was combined with the data from wearables, the machine learning model achieved a 65 percent improvement in predicting happiness.

The model also achieved a 54 percent improvement in predicting one's self­assessed health prediction, a 55 percent improvement in predicting the positive attitude and a 38 percent improvement in predicting success.

This study asserts (断言) that without social network information, we only have an

incomplete view of an individual's wellness state.“To be fully predictive or to be able to obtain intervention (干预), it is  critical  to be aware of the social network，” Chawla said.

1．What did the study find?

A．How people choose their friend circles.

B．What factors decide your friend circles.

C．How your circle of friends influences you.

D．What your circle of friends says about your health.

2．How did the researchers draw their conclusions?

A．By comparing data.

B．By giving examples.

C．By analyzing the cause and effect.

D．By describing personal experiences.

3．What does the underlined word “critical” mean in the last paragraph?

A．Easy.　　　　　 B．Common.

C．Important.  D．Challenging.

4．What do Chawla's words in the last paragraph tell us?

A．How fitness devices can connect your circle of friends.

B．A person's social network is part of his health picture.

C．The best ways to make friends and keep a healthy social circle.

D．The wearable devices are not useful for understanding someone's health.

[语篇解读]　本文是一篇说明文。一项研究表明朋友圈有助于人们更完整、更客观地了解自己的健康状况，本文在此基础上介绍了社交网络对人际关系的影响。

1．D　[细节理解题。根据第一段中的“Your circle of friends may help you get a better reading of your overall health and wellness”可知，你的朋友圈可能会帮助你更好地了解你的整体健康状况，故选D。]

2．A　[细节理解题。根据倒数第二、三、四段可知，与Fitbit上的健康行为数据相比，研究也结合了社交网络结构所提供的幸福感预测、自我评估的健康预测、积极态度预测、成功预测等几个方面的数据，可以看出，研究人员是通过比较数据得出结论的，故选A。]

3．C　[词义猜测题。根据最后一段的“This study asserts (断言) that without social network information，we only have an incomplete view of an individual's wellness state.”可知，该研究称，如果没有社交网络信息。我们只能得到不完整的个人健康状况的信息。由此可推断，如果仅依靠某些数据平台的数据不能获得完整和客观的信息，还需要借助社交网络，所以此处指社交网络是非常重要的，故critical意为“重要的”，相当于important，故选C。]
