   Smartphones have been blamed for everything from taking drivers’attention from driving to keeping people on the sofa scrolling (滚屏) videos. But the smartphone that seems to be everywhere could just easily increase physical activity if it pushes its owner’s buttons in the right way.

New research shows that making social connections (人际关系) through activity-tracking apps gets people to move more. And another study on the “Pokemon Go” phenomenon shows that the smartphone game got players to take thousands more steps than usual. Together, the studies show the potential (潜在性) of smartphones to push a range of people to be more active.

People who linked with friends on the activity-tracking app increase their steps by 400 a day on average, compared with people who made no social connections, according to Tim Althoff and two other computer scientists at Stanford University. Such opinions show the possibilities of smartphones and games to help with one of the most stubborn public health problems — that even people who want to be active have trouble staying active.

An NBA video game, for example, will give players extra powers in the game if they reach a step goal in real life. The app “Zomies, Run!” uses audio stories to push people to run more or run faster.

Still, there is room for growth: Only about 4% of all health apps use “gamification”, such as point- scoring or competition, according to a study published in October in BMJ Open. “Gamification is actually quite closely linked with behavior change techniques,” says Dr. Elizabeth Ann Edwards, the study’s lead author.

【小题1】According to the “Pokemon Go” phenomenon, smartphone users become more active because __________ .
A.they have more social connectionsB.they get extra powers in life

A.By showing the results of some research.
B.By explaining the functions of smartphones.
C.By giving clear description of some games.
D.By analyzing the causes of public health problems.

   As Internet users become more dependent on the Internet to store information, are people remember less? If you know your computer will save information, why store it in your own personal memory, your brain? Experts are wondering if the Internet is changing what we remember and how.

In a recent study, Professor Betsy Sparrow conducted some experiments. She and her research team wanted to know the Internet is changing memory. In the first experiment, they gave people 40 unimportant facts to type into a computer. The first group of people understood that the computer would save the information. The second group understood that the computer would not save it. Later, the second group remembered the information better. People in the first group knew they could find the information again, so they did not try to remember it.

In another experiment, the researchers gave people facts to remember, and told them where to find the information an the Internet. The information was in a specific computer folder (文件夹). Surprisingly, people later remember the folder location (位置) better than the facts. When people use the Internet, they do not remember the information. Rather, they remember how to find it. This is called “transactive memory (交互记忆)”

According to Sparrow, we are not becoming people with poor memories as a result of the Internet. Instead, computer users are developing stronger transactive memories; that is, people are learning how to organize huge quantities of information so that they are able to access it at a later date. This doesn’t mean we are becoming either more or less intelligent, but there is no doubt that the way we use memory is changing.

【小题1】The passage begins with two questions to ________.
A.introduce the main topicB.show the author’s altitude
C.describe how to use the InterneD.explain how to store information
【小题2】What can we learn about the first experiment?
A.Sparrow’s team typed the information into a computer.
B.The two groups remembered the information equally well.
C.The first group did not try to remember the formation.
D.The second group did not understand the information.
【小题3】In transactive memory, people ________.
A.keep the information in mind
B.change the quantity of information
C.organize information like a computer
D.remember how to find the information
【小题4】What is the effect of the Internet according to Sparrow's research?
A.We are using memory differently.
B.We are becoming more intelligent.
C.We have poorer memories than before.
D.We need a better way to access information.
