However, if the cars become popular, there will be problems with traffic .

 3-D printing is new technology for the future. 3-D printers are used to make life-size models of car parts, and man-made body parts, such as ears.

A Frenchman Niepce, needed pictures for his business. But he was not a good artist. So he invented a very simple camera in 1826. He put it in a window of his house and took a picture of his garden. That was the first photo.

The next important date in the history of photography (摄影术) was in 1837. That year, Dagueme, another Frenchman, took a picture of his reading room. He used a new kind of camera in a different way. In his picture you could see everything very clearly, even the smallest thing.

In 1840, photography was developed once more. Then photographers could take pictures of people and moving things. But the photographers had to carry many machines.  

With the development of science and technology, a Chinese young man Wang Mengqiu, invented Hover Camera (无人相机). It can record people and things more wonderfully. He once studied at Stanford University in the United States. He became famous overnight because of the invention.

Hover Camera records movements with a 13MP camera and takes 4K videos. You can use a smartphone to control it. It can follow you, flying or staying in mid-air. In this way, it can get the perfect pictures. It is the best choice for weddings, sports games and holidays because Hover Camera is convenient for the users to carry. It can be folded, so it can be put into a small bag. When the power is low, it can land safely.

In the future, cameras will be designed better and better. People can take more lively photos and videos.

Here are some tips that can help you have a few moments of quiet in your day:

1 Make it a priority(优先的事物). Like brushing your teeth or taking a shower，10 minutes of quiet time a day is part of taking care of your body and cultivating (陶冶) your spirit.

2 Teach the people you live with about quiet time. No television or computer or music. This is the time to read or play or create art alone. Tell the people around you about the importance of quiet and lead by example. Then they'll begin to support you and enjoy it as well.

3 Use the spaces in between. I seldom have the radio on in the car when I'm driving alone. When I'm waiting for an appointment(约会), I seldom text or talk just to enjoy the quiet before the appointment.

4 Create at least one daily activity that needs quiet. Go for a run without earphones. Take a long bath, or a shower before bed. My morning coffee is a time of enjoying quiet. When I know I've got a very busy day ahead, I'll get up 15 minutes early just to drink coffee alone in the quiet.

Creating pockets of quiet is a powerful way to make your life full of energy. You'll feel better to manage the challenges of your day.
