When our restaurant business failed, we headed north in a camping truck to Texas, hoping to have a “fresh start”.
At the 1of Palo Duro Canyon (峡谷) State Park, I 2a job advertisement hiring park hosts. The position offered a 3, permanent campsite in the park, and 4, the hosts served as a link between the park's guests and the rangers (护林人). It was the perfect solution: a rent-free place to reorganize our lives. We entered the park and I made an 5for the following day.
The park was6, so it took us some time to find an available site. That evening, as we finished our dinner, my wife saw two large skunks (臭鼬) walking toward our table. We7climbed onto the table and, for the next four hours, waited for them to 8our camp.
Having survived that night, we were 9that everything else would be all right. The next day we met with the people who ran the park. They explained our10and gave us a beautiful campsite.
That evening, 11, we learned about the canyon 12 They were strong and cold, rocking our little camping truck violently, and we lay 13 in the dark until the winds died away.
14the weeks that followed, we learned to survive in our truck and 15the little money my wife16by substitute teaching. Building a successful business and then losing it had left very little time for building a successful 17. For a time after our business 18I thought I might lose my family as well.
Living in the tiny19with no television, we sat close together reading and talking. One evening, standing under a jeweled sky, I found myself 20for all the hardships. We had walked the trails and climbed the canyon walls. We had become a family!
Global Positioning System (GPS) is now a part of everyday driving in many countries. It is a space-based system that provides position and time information in all weather conditions. GPS can help people get to where they want to go.When this happens, the driver is often to blame. Sometimes a GPS error is responsible. Most often, it is a combination of the two.
Barry Brown, a GPS technologist, took an incident as an example. His friend once flew to an airport in the eastern United States. There he borrowed a GPS-equipped car to use. He wrongly plugged in the home address in the west. It wasn't until he was driving for thirty minutes that he realized it. Mr. Brown says this is a common human error. But he says, “One problem is that GPS has a very small screen and it can just tell you the next turn.”
“The Normal and Natural Troubles of Driving with GPS” lists several areas where GPS can cause difficulties. They include maps that are outdated, incorrect or difficult to understand. GPS may fail due to these reasons and then lead to confusion for the drivers.
Although GPS sometimes causes difficulties when people are driving, the most attractive point of this system is its 100% coverage on the planet. It is important for you to have to know what you are doing when you use GPS. You need to have the “ability” to be able to use GPS because it sometimes goes wrong.
A. There are quite a few situations showing the problems of using GPS.
B. That means that it is not really telling you about going to the wrong place.
C. This space-based system is an important tool for civil and commercial users.
D. But sometimes it sends you to the wrong place or leaves you completely lost.
E. They also contain timing problems related to when GPS commands are given.
F. Advances in technology play an active role in modernizing GPS in many ways.
G. To make GPS well used, you need a good understanding of how drivers and GPS work.
