Los Angeles is known as a driving town. As the Missing Persons’ song goes, “Nobody walks in L.A.” In the city, people are so busy driving to work. Even for the usual shopping, it’s hard to see people walking in the street.

Chuck McCarthy wants to change it! The actor gave up the job of earning money. And he has a new special job now—“people walker”. The idea for the business came when he wanted to make some more money. “I thought about walking dogs at first, but I didn’t want to pick up dog poop(粪便). That’s less interesting.” Many customers need the special service because they are lonely, or they enjoy the feeling of being safe. “My words are full of friendship and warmth, but I can tell you that they are conversations, not one-sided monologue（独白）.”

Just walking and talking and knowing that someone is listening can be helpful for most people. They were very pleased with McCarthy’s job because he listened to them. He walks with others for $7 per mile (around 50 yuan per kilometer).

McCarthy is happy to lend his ear to the people of L.A. and listen to what they have to say. He now has his own company that offers this walking service. He has about 35 walkers working for him. Would you like to try this service?

Competition is good for businesses. In the world of positioning systems, however, competition is also a must. 1. Now, China is building its own positioning system. It’s called Beidou.

2.With it, the country no longer has to rely on foreign systems. It also shows the world that China has made much technological progress.

They began operations at the end of 2018. To further improve the system, China will send ten more Beidou satellites into space. It plans to complete the system before 2020.
