Sometimes it's necessary to take a break, relax and forget the routine (日常工作), so I know of an excellent place to do it outside the city. It's a beautiful place and I really enjoy going there.

    The name is Tepoztlán, 71 km south of Mexico City. Here you can find a lot of different meals, beautiful landscapes, historical buildings, local souvenirs, and so on.

    The weather most of the time is very hot, and I have to give you some advice if you go.

    I give you this advice because I ended up with sunstroke. I'm going to tell you how my trip started. When we got there we were really starving, so we decided to have breakfast and when we go to Tepoztlan we usually enjoy "quesadillas" in the market.

    In Mexico, it's very common to eat in the market, but these kinds of markets not only sell food but also you can buy clothes, flowers, everything you can imagine.

    Tepoztlan has a lot of tourist sites, but the main attraction is Tepozteco hill, and it's more attractive for the visitors during "Spring Equinox". To be honest, I've never climbed it, I'm too lazy to walk a lot and even more in the sun.

    In my trip we didn't have time to do all that because one day is not enough, but if you have the opportunity to stay for more than one day it's an excellent idea.

    Many people don't realize the importance of music education in the schools today. A new study showed, however, music education is extremely important.

    In college, music education is one of the largest programs. Teachers have to learn general education materials and techniques. They must learn to play every instrument; they must learn music history and music theory; they must learn instrument repair and teaching methods; they must learn conducting and so much more. At the same time, much of our culture and tradition is absorbed in music.

    Music plays a very important role in our education.

    Music helps with math and science. Students learn to count, and how to multiply and divide. Students also use science to help them discover what sounds good together and what doesn't. Students also need science to understand something called the “overtone series", which is about how music is produced by vibration（颤动）and why.

    Students learn a lot about languages through music．Many songs are written in other languages, including ancient ones. Students must learn to translate these works to understand what they are singing about. A song is likely to be a famous short work set to music; so students are exposed to that very often while singing.

    Students learn a huge amount of cooperation （协作）of body parts through music, so parts of the body can work better together. Students must use motor（肌肉运动的）skills in order to play an instrument. Singers and wind（管乐器）players must learn breath control and be in good shape to play.

    Students learn about art. Some famous pieces were written about important pieces of art, and students learn about the artists and styles as they're playing the music.

    Music education also brings higher thinking to our children. It allows them to think about complex patterns. Students have to be aware of what every other musician does at every time. In that way, it develops cooperation, as well. They tend to develop more ability for learning.

    As one can see, music is very important to education.

                                                Inventor Creates Wheels That Let Cars Roll in Any Direction

    Omnidirectional wheels have been around for a while, but they are mostly used on utility(实用的) vehicles like forklifts. London-based inventor William Liddiard has created a special set of all-around wheels that can be bolted on to any car, allowing it to move in any direction, spin 360 degrees and slide into a parallel park with ease.

    "Unlike other all-around capable wheels, my wheels do not require the vehicle to be built around them. This is a world first bolt-on application for anything with wheels." Liddiard wrote in the description of a You Tube video he uploaded to show how his invention works on an old Toyota Echo. "They are stronger, faster, and more accurately controlled than previous technology. They can take a beating. The tires can have the same build characteristics (siping, grooves, rubber compounds etc.) as regular tires. Now you can drive in all directions, and tum on the spot, when needed."

    While the "Liddiard Wheels" shown in the video are just proof of concept prototypes(原型机), they seem to work as described by the inventor. His car can be seen spinning in place and sliding from one side to the other as the tires move under the power of 24,000 pounds of torque (扭矩) applied directly to them.

    William is now hoping that the power of social media will help him get his invention out there and eventually team up with a company willing to help him improve the wheels and eventually bring them to the market.

    "Will a set of wheels make sideward parking an easy thing? Yeah, I'm pretty sure these things will be in high demand if they ever end up on the market." the inventor said confidently.

    We've all had cases where we've waited just a bit too long to pay an electric bill or speeding ticket. But one man, from California by reasonable assumption, who goes by “Dave”, recently took procrastination (拖延) one step further, by paying a parking ticket almost a half-century after it was given.

    In December 2018, the Minersville Police Department in Pennsylvania received a letter in the mail. Whoever wrote the letter decided it was best to keep his name somewhat unknown, so he put the return address as “Wayward Road, Anytown California” under the name “Feeling guilty”.

    When the officers opened the envelope, they found a brief letter, along with a $5 bill, and a parking ticket dating all the way back to 1974.The note read, “Dear PD, I've been carrying this ticket around for 40 plus years always intending to pay. Forgive me if I don't give you my info. With respect, Dave.”

    Even though the initial parking ticket was only for $2, “Dave” must have felt awfully guilty because he left 150 percent, or $3, in interest.

    Michael Combs, the Police Chief of the Minersville Police Department, stated in an interview that the same ticket would cost about $20 if it was given today. Combs went on to share that the original ticket from 1974 was given to a vehicle that had an Ohio license plate.

    Because there was no system for tracking tickets given to out-of-state cars back then, “Dave” could have gotten away with never paying the $2 fine. But apparently, guilt got the best of him, and he decided to finally cough up the money more than 40 years past its due date.

    “The world feels anxious and divided, and Facebook has a lot of work to do whether it's protecting our community from abuse and hate, defending against interference by nation states, or making sure that time spent on Facebook is well spent,” Zuckerberg wrote on Facebook in January.

    If the tech firm succeeded, Facebook would end 2018 on a much better path. But the cracks in Zuckerberg's social media empire only grew as scandals(丑闻)about data misuse, security and even Facebook's leadership piled up.

    The social network has faced criticism many times since launching 14 years ago, but the public uproar reached new heights in 2018. Facebook's missteps, even as it tried to fix its problems, were yet another reminder of what happens when a company grows rapidly with little oversight(监管). They also set the stage for another showdown between the tech powerhouse and lawmakers who have their own ideas on how to manage a platform used by 2.3 billion people every month.

    “I think there's just a general growing consensus from both parties in Congress that self-policing is not going to work,” Democratic senator Mark Warner of Virginia said in an interview. Facebook pointed to a series of notes Zuckerberg published this year outlining what the tech firm has done to combat(战斗，争论)election meddling(好干预的), as well as hate speech, misinformation and other offensive content. The social network pulled down more than 1.5 billion fake accounts, launched a database of political ads and announced the creation of a Supreme Court like independent body to oversee content appals.

    But in many ways, Zuckerberg fell short of his New Year's resolution(决议). UN investigators said Facebook played a role in spreading hate speech that fueled ethnic cleansing(清洗)in Myanmar. Media outlets found loopholes(漏洞)and errors in Facebook's political ads database. Users questioned whether they should delete Facebook after learning that Cambridge Analytical, a UK political consulting firm with ties to Donald Trump's 2016 presidential campaign, gathered data on as many as 87 million Facebook users without their permission.

    In short, Facebook's problems ballooned out of the company's control.

“They created a platform where sharing was mindlessly easy and interacting with each other required almost no forethought at all,” said Woodrow Hertzog, a law and computer science professor at Northeastern University. “As a result, there was massive sharing, including leaking of personal information that put lots of people at risk.”

    Once a teacher was giving her young students a lesson on how the government works. She was trying to explain the principle of income tax(所得税).

    "You see," she began speaking slowly and carefully, "each person who works must pay part of his or her salary to the government. If you make a high salary, your taxes are high. If you don't make much money, your taxes are low."

    "Does it make sense?" she asked. "Does everyone understand the meaning of income tax?" The students nodded.

    "Are there any questions?" she asked. The students shook their heads.

    "Very good!" she said. "Now, I would like you to take a piece of paper and write a short composition on the subject of income tax."

    Little Joe was a slow learner. He had lots of problems with spelling and grammar, but at least this time he seemed to understand the task. He took his pen and after a few minutes, he handed the teacher the following composition: Once I had a dog. His name was Tax. I opened the door and in come Tax.
