How fit are your teeth? Are you lazy about brushing them? Never fear: An inventor is on the case. An electric toothbrush senses how long and how well you brush, and it lets you track your performance on your phone.

    The Kolibree toothbrush was exhibited at the International Consumer Electronics Show in Las Vegas this week. It senses how it is moved and can send the information to an Android phone or iPhone via a Bluetooth wireless connection.

    The toothbrush will be able to teach you to brush right (don't forget the insides of the teeth!) and make sure you're brushing long enough. “It's kind of like having a doctor actually watch your brushing on a day-to-day basis,” says Thomas Serval, the French inventor.

    The toothbrush will also be able to talk to other applications(应用) on your phone, so developers could, for example, create a game controlled by your toothbrush. You could score points for beating monsters(怪物) among your teeth. “We try to make it smart but also fun,” Serval says.

    Serval says he was inspired by his experience as a father. He would come home from work and ask his kids if they had brushed their teeth. They said “yes,” but Serval would find their toothbrush heads dry. He decided he needed a brush that really told him how well his children brushed.

    The company says the Kolibree will go on sale this summer, for $99 to $199, depending on features. The U.S. is the first target market.

    Serval says that one day, it'll be possible to replace the brush on the handle with a brushing unit that also has a camera. The camera can even examine holes in your teeth while you brush.

    The main hall of a 135-year old temple in Shanghai will be moved 30 meters to its north in order to create more space for visitors. Thousands of people gather and see the moving of the temple that started on Saturday.

    The Mahavira Hall, of Shanghai's Jade Buddha Temple, was built in 1882. The temple in downtown Shanghai attracts more than two million visitors a year. Daily visitors can reach as high as 100,000.

    A major renovation project started in 2014. The moving of the temple started on Saturday and is set to be finished in two weeks. The main hall of the temple will be relocated 30.66 meters northward within the temple and elevated 1.05 meters.

    Master Jue Xing, abbot of the Jade Buddha Temple and vice president of the Buddhist Association of China, said moving the hall will create more space between buildings and reduce the risks of a stampede as the temple is usually tightly packed.

    Buddhist statues and relics in the hall will also be moved together with the hall, he said.

    Workers pumped cement into the foundation of the hall because the old building's foundation was rather soft, he said.

    Statues and other relics in the building were stabilized and protected with frames to avoid damage, he said.

    The moving will be carried out with the help of relic preservation experts from the Shanghai Museum, he said.

    Shanghai has had several successful projects to move old buildings, including a school in 2009 and a concert hall in 2002. On Aug. 31^st, Shanghai Concert Hall began to move 66.46 meters northward after the last concert was held in the previous location and reopened to audience two years later. The moving was recognized as a wonder of construction protection and inspired the experts of the moving of the the Mahavira Hall.

    When was the last time you told someone they inspire you to go to work each morning?

    Teachers at Oak Park High School in Kansas City, Missouri, did just that this September, when they pulled individual students out of class to tell them just how much they appreciated them.

    The students' reactions, which were captured (捕捉) on video and shared on YouTube in a now-viral video, ranged from shy thanks to hugs and tears.

    “I have been challenged to find a student who makes me want to come to school every day,” says one teacher in the video, “and that's you.”

    Jamie McSparin, a teacher in charge of the school's academy program for at-risk sophomores （二年级学生）and juniors, posed the challenge, writes ABC News.

    “Initially when we pulled the kids out, they all thought they were in trouble,” McSparin told ABC News. “Any teacher-student interaction always seems to be negative (消极的), and that was something that bothered me, too. No matter if they're a good kid or a trouble maker or anything, they always thought they were in trouble,” she says.

    McSparin says she got the idea for the project after attending a professional development workshop this summer called the power of positivity.

    “I like the idea of letting students know they are appreciated, because we do appreciate them, I just don't think we say it enough,” she told local news outlet WDAF-TV.

    It's safe to say the challenge was effective.

    “I feel special,” said one of the boys in the video. “You should,” said his teacher. “You are special.”

Wilderness

    "In wilderness(荒野) is the preservation of the world." This is a famous saying from a writer regarded as one of the fathers of environmentalism. The frequency with which it is borrowed mirrors a heated debate on environmental protection: whether to place wilderness at the heart of what is to be preserved. 

    As John Sauven of Greenpeace UK points out, there is a strong appeal in images of the wild, the untouched; more than anything else, they speak of the nature that many people value most dearly. The urge to leave the subject of such images untouched is strong, and the danger exploitation(开发) brings to such landscapes(景观) is real. Some of these wildernesses also perform functions that humans need—the rainforests, for example, store carbon in vast quantities. To Mr.Sauven, these "ecosystem services" far outweigh the gains from exploitation.

    Lee Lane, a visiting fellow at the Hudson Institute, takes the opposing view. He acknowledges that wildernesses do provide useful services, such as water conservation. But that is not, he argues, a reason to avoid all human presence, or indeed commercial and industrial exploitation. There are ever more people on the Earth, and they reasonably and rightfully want to have better lives, rather than merely struggle for survival. While the ways of using resources have improved, there is still a growing need for raw materials, and some wildernesses contain them in abundance. If they can be tapped without reducing the services those wildernesses provide, the argument goes, there is no further reason not to do so. Being untouched is not, in itself, a characteristic worth valuing above all others.

    I look forwards to seeing these views taken further, and to their being challenged by the other participants. One challenge that suggests itself to me is that both cases need to take on the question of spiritual value a little more directly. And there is a practical question as to whether wildernesses can be exploited without harm.

    This is a topic that calls for not only free expression of feelings, but also the guidance of reason. What position wilderness should enjoy in the preservation of the world obviously deserves much more serious thinking.

    High school was a hard time for Me in the beginning because I had just moved to a small town and knew basically no one. I loved to play basketball but was afraid to go to tryout (选拔)for the school's team because I didn't know anyone. One day all that changed when I missed the bus home and decided to shoot baskets on the school playground to kill time. The coach Mr Colbath had been watching me make various baskets and was pretty impressed with my moves.

    He came up to me and asked me who had taught me to play like that. I told him that my dad had taught me how to play basketball. He asked me if he would see me at the tryout on Friday, but I said no and told him why. He told me to have a try because I played very well and would maybe make some friends on the court. After thinking for a few minutes. I finally decided to have a try.

    On the day of the tryout, the coach came, found me and helped me practice before the tryout. He helped me a lot and I did very well at the tryout and many members of the team were quite impressed. I did make the team and over the next few years the coach helped me both on and off the court. He helped me do my math which I had such a difficult time with and he even taught me how to live independently.

    I will never forget Mr Colbath. He really inspired me and changed my life. I would not be the person that I am today if he had not taken such an interest in me when I was in high school.

When it comes to helping students learn and mature, there are several ways to increase their well-being. Although your children may be succeeding in the classroom, there are a few things that you still can do.

Encouraging physical activity is the first thing you can do. More and more children do not participate in sports after school. It's important for you to encourage mobility with sports played after class. You should find sports equipment, basketball courts and play areas where kids can increase their well-being. {#blank#}1{#/blank#}

Secondly, you can provide proper nutrition for your children. It's important for your children to receive proper nutrition both inside and outside of the home. {#blank#}2{#/blank#}You'd better make it a point to provide enough nutrition for their proper development and growth.

{#blank#}3{#/blank#}Many parents fail to stop children from using smartphones and computers. There are some institutions that even encourage too much screen time as a way to teach children or keep them entertained. You should help the children remain excited without sitting in front of a screen throughout the day.

Last but not least, monitoring bullying(欺凌) is also an essential part. Bullying continues to remain a common problem in some schools, making it important that the environment that your children grow in holds a high standard.{#blank#}4{#/blank#}

It's important to examine the school life as a whole to determine what factors are missing. {#blank#}5{#/blank#}You may determine how well they adjust to the world around them and succeed in life.

A. You should provide kids with fresh food.

B. Besides, you'd better limit their screen time.

C. It will encourage children to focus on their study.

D. In addition, try your best to give them more freedom.

E. This will reduce the risk of health conditions that include obesity.

F. You can advise teachers to keep a practice of looking for bullying.

G. Parents play a significant role in children's growth and well-being.
