We all know that many inventions play important roles in our daily life. They have changed our life a lot. Here are some interesting inventions.

Morpher	People refuse to wear helmets because they’re thick and heavy. Morpher is a bike helmet made of plastic. It is just as strong as traditional helmets, but it can be folded almost completely flat, making it easier to carry. Morpher may be available for sale in stores in the near future.
HyperAdapt	Have you ever seen the movie Back to the Future? Maybe everyone wants the pair of shoes in the movie that can tighten or loosen by themselves. Now, thanks to the Shoe Factory, the dream is realized. When you push a button on the shoe, HyperAdapt can tighten or loosen around the feet.
Flyte	Flyte is a light bulb that can float (漂浮) and turn. Flyte has been popular with most people since it came out in January. The company also introduced a lot of similar products, including a planter, Lyfe, which came out in June.
Little Printer	It looks lovely and is called Little Printer. This machine can print news headlines (摘要)，riddles and other things on a roll (卷) of paper. If you want to make your own little newspaper, don’t forget to use it.

“Without music, life would be a mistake,‍” famous German philosopher (哲学家) Friedrich Nietzsche said over a century ago. Music is a big part of our lives. But in recent years, some US schools have cut music classes to control budgets (预算).

For example, Chicago Public Schools hurt arts education when it fired (解雇) over 1,000 teachers. Among them, 10 percent of the teachers taught art or music, according to The Washington Times. In fact, this is not just a problem in the US. In other countries, such as China and the UK, music classes are not thought to be as important as ones like science, math and history. That’s partly because music is not seen as a very important life skill, and it isn’t tested. Many students are busy with schoolwork, so parents and students choose to focus on subjects that are tested more often.

However, learning music is beneficial (有益的) in many ways.

When playing music, you need different abilities to work together. It is not as simple as it looks, according to Kenneth Guilmartin of Music Together, an early childhood music development program. For example, when playing the piano, people see music notes and decode (解码) them in their brains. They also use their fingers to make sounds. You need to deal with all these things at the same time.

Music has a special connection with science as well. You can see that many scientists are good at playing music: Einstein played the violin, and German physicist Max Planck was talented in playing the piano.

When I was a boy, my family would sometimes gather together at my great aunt’s small house over the summer. Relatives from all the country would come to visit.

The adults would crowd together in the living room, around the kitchen table and on the front porch (门廊) to talk and catch up on each other’s lives. All of us kids would be sent out onto the front yard to play.

Those were the days before video games and smartphones, so we often ended up playing a good old-fashioned game of tag (捉人). I remember one of those times especially.

I was the youngest and smallest of all the kids there, so I got caught first and couldn’t catch anyone else. Although I tried my best to chase after my brothers and cousins, they were all too fast for me. I grew more and more frustrated.

I finally lunged at one of my brothers and fell face-first into the dirt. I got up with tears in my eyes. Then I saw one of my cousins standing there. She started to run but was going much slower than before, I easily caught up and tagged her. Then she turned to me, smiled and said, “I’m it! You’d better run!” I ran off laughing with glee while she turned and started to chase one of my older brothers.

I see now how her act of kindness that day saved me from sadness and returned me to joy. It didn’t matter that we hardly ever saw each other. We were family and she love me. We are all one, we all belong to each other and we are one big, beautiful family.
