Sarah ________ the man and offered him her coat.

Little did Sarah know that her simple act of ________ would make a huge difference.

Encouraged by her, people began organizing events to ________ those less lucky. Schools added lessons on the ________ of helping others, and businesses started a “pay it forward” project, where people could buy more and leave the ________ meal for those in need.

Reflecting on this unbelievable journey, we can ________ our individual power, which may create an effect that would ________ reach every corner of the globe.

2 . Once there was a farmer with a wife and two sons. He became quite________through hardworking. He wanted his children to have a(n)________life, so he and his wife did all the work and________made them do anything.

After some time, his wife died and________he didn’t want his children to________, so he did the field labor and all the housework. But as time went on, he became old and________, and started to worry about his________when he died.

So he thought about this for a long time and he________his sons and said, “Look, my inheritance (遗产) to you is a lot of gold. I’ve________all my gold in the fields, so it’s up to you to plough (耕作) them and________the gold.”

And he called his neighbors and said, “I’m going to________and my children don’t know how to________themselves. So please cook for them until they can take care of themselves.”

So the neighbors provided them with________for some time.

Certainly the brothers didn’t want to be robbed of the________so they did the digging themselves. They________one field after another and after they had dug all the fields, they found no gold.

So the brothers sat down and one________the other, “Do you think our father________us?”

But the other brother said, “No, I think our father was saying that the________is a golden profession. And if we dig up all the________we can become rich.”

So like all the other________, they sowed wheat in the fields they had dug and became very rich in the end.

3 . Ways to Put Down Your Smartphone

For most people, when they wake up in the morning, the first thing coming to their mind is to find their smartphone. If it is the same to you, it is time for you to put your smartphone down.    1    

Pick up a newspaper

Read a newspaper and be amazed at how relaxing it is to read through the day's news. We will find our attention has increased and we will enjoy reading it.    2    Even the New York Times is only $9 a week for home delivery, plus digital access.

    3    

Take your old radio out again, plug it in, and be amazed at how vital radio still can be. More importantly, you won't be attracted to check other apps and websites.

Cut off social media ties

We love Facebook or Twitter to communicate with friends and relations.    4    And turn off app and email information at some other time in any other places, so you aren’t attracted by them. Pile up your phones

Today, it seems nearly impossible to put your phone down for 60 minutes. However, whether dining at home or out on the town, stick to (坚持) a no-device policy.    5    Even better, you can also have a waiter place them out of site, so no one can break the policy.

6 . Have you ever imagined an insect-inspired robot, which weighs less than a gram, could one day help out in surgery (外科手术)?

Scientists have designed this small, “insect-bot” called mCLARI that can control and even change its body shape as it travels in different environments to fit through gaps. It’s 2 centimeters long, weighs less than 0.97 grams and can travel at a speed of 6 centimeters per second.It’s the smaller, faster replacement to CLARI, which was designed by the same team.

“Because of the robot’s small size and ability to change shape, we expect usage of this technology in four important areas,” the lead author Kaushik Jayaram said. These include disaster (灾害) response , check on high-value objects, environmental monitoring and medical treatment.

“In the long term, we hope such robots will be used more widely in moving through human bodies and performing surgeries that can’t be easily done at present,” Jayaram said. With mCLARI, Jayaram’s team is moving closer to creating robots that can fit in different environments—just like the insects they’re inspired by.

The mCLARI robot has four legs and can move in narrow spaces by changing between running forward and side-to-side and can use different speeds in human bodies. Its legs are joined to its body through joints (关节), which enables mCLARI to change its body shape based on the environment it is in. For example, its legs can be lengthened up to 50% in certain spaces.

As follow-up work, the scientists want to give mCLARI more power and sensing ability while helping the surgeries. “We are also excited about understanding the effect of shape change on improving functions of robots,” Jayaram said. “And this is sure a great one-step forward of the technology. The robot will have entered the market by 2025 and will bring greater benefits to mankind, especially in medical treatment.”

8 . A new study, led by Dr. Rebecca Stone, has shown that children as young as four years old eat 79% more calories when they are bored, compared to when they are in a normal mood (情绪) .

The researchers have explored the behaviors that make children more likely to eat when they experience negative emotions. Often when children experience bad emotions such as boredom or sadness, caring adults will use food to soothe them. However, this behavior, known as emotional feeding, appears to increase the possibility of children eating more when they are in low spirits. As time passes, too many calories intake will have a significant effect on children’s health both mentally and physically.

Dr. Stone stresses that the experience of boredom is important in the development of children’s sense of self and creativity, so she does not recommend that children should avoid being bored. Instead, she suggests children learn to experience boredom without turning to food. She also suggests that parents turn their children’s attention away from food when they feel bored, or restructure the home food environment to make it less likely that children turn to food in response to being bored.

While there do appear to be individual differences between children in terms of their eating when bored, it is helpful to know that the feeding practices that adults use around food might shape the likelihood of this happening. Although it is attractive to use food as a tool to help children, emotional feeding might lead to greater emotional eating in the future. It is important for parents and caregivers to be aware that this short-term fix could create future problems.

It is hoped that, on the original basis of the study, the team will deeply explore other negative mood states in children and offer advice and support for families to find more effective ways to manage challenges around children eating behavior.
