Put down the phone and live in the moment

Have you ever unintentionally left your phone at home and wondered how you would get through the day? Baylor College of Medicine’s Dr. Jin Han explains why this might be a sign that you need to put down your phone more often.

“There has been a(n) 【1】 in technology as our phones have gone from just regular cell phones to smart phones that allow you to multitask all with one device,” said Han, assistant professor at Baylor. “You use your phone now to receive emails, to text and chat and to access social media platforms -- 【2】 your phone may be your connection to your social life.”

Although they offer many advantages, Han cautions that using your smart devices can be harmful if you use them too much. For example, using your smart phone while driving, or even walking, can cause serious accidents. Also, staring at your screen for too long can be harmful to your 【3】.

Being 【4】 too long to your phone also can impact the quality of your relationships, he said. If you are on your phone constantly and not 【5】 with those around you, it can take away from your relationships with your family and friends. In addition, if you are using your phone too much in front your children, then they will likely follow your lead and use their own smart devices rather than 【6】 with you.

“ In the end, the question is how you balance using your phone while not negatively 【7】 your health.” Han said. “Anything that you are doing to the 【8】 is no healthy anymore. While it is going to be almost impossible not to use this technology, we have t create a behavior that is healthy.”

To help 【9】 the time you spend on your phone, Han offered the following tips:

Limit the time spent on your phone: Set up certain time that you allow yourself to be on the phone.

Do not use your phone at night: Being on your phone late into the night can make it harder for you to fall asleep and wake up the next day. Restricting your phone use at night can help you 【10】 a healthy sleep behavior.

【題目】Directions: Fill in each blank with a proper word chosen from the box. Each word can be used only once. Note that there is one word more than you need.

Bill Drayton believes we’re in the middle of a necessary but painful historical transition. For millenniums most people’s lives had a certain 【1】. You went to school to learn a trade or a skill-baking, farming or accounting. Then you could go into the workforce and make a good living repeating the same skill over the course of your career.

But these days machines can do pretty much anything that’s 【2】. The new world requires a different sort of person. Drayton calls this new sort of personal changemaker.

Changemakers are people who can see the patterns around them, identify the problems in any situation, figure out ways to solve the problems in any situation, figure out ways to solve the problem, organize fluid teams, lead collective action and then 【3】 adapt as situations change.

For example, Ashoka fellow Andrés Gallardo is a Mexican who lived in a high crime neighborhood. He created an app, called Haus, that allows people to 【4】 with their neighbors. The app has a panic button that 【5】 everybody in the neighborhood when a crime is happening. It allows neighbors to organize, chat, share crime statistics and work together.

To form and lead this community of communities, Gallardo had to possess what Drayton calls “cognitive empathy-based living for the good of all.” Congnitive empathy is the ability to perceive how people are feeling in 【6】 circumstances. “For the good of all” is the capacity to build teams.

It doesn’t matter if you are working in the cafeteria or the inspection line of a plant, companies will now only hire people who can 【7】 problems and organize responses.

Millions of people already live with the mind-set. But a lot of people still inhabit the world of following rules and repetitive skills. They hear society telling them: We don’t need you. We don’t need your kids, either.” Of course, those people go into reactionary mode and strike back.

The central 【8】 of our time, Drayton says, is to make everyone a changemaker. In an earlier era, he says, society realized it needed universal 【9】. Today, schools have to develop the curriculums and assessments to make the changemaking mentality universal. They have to understand this is their criteria for success.

Ashoka has studied social movements to find out how this kind of 【10】 shift can be promoted. It turns out that successful movements take similar steps.
