問題詳情:
For many people, leisure time is an opportunity to get outdoors, have some fun and meet interesting people. Add two pieces of advanced 21st century technology — global positioning system (GPS) devices and the Internet — to get “geocaching”.
The word geocaching comes from “geo” (earth) and “cache” (hidden storage). Geocachers log onto a website to find information about the location of a cache — usually a waterproof plastic box containing small items such as toys and CDs — along with a notebook where “finders” can enter comments and learn about the cache “owner”, the person who created and hid the cache. Finders may take any of the items in the cache but are expected to replace them with something of similar value. They then visit the website again and write a message to the owner.
Geocaching became possible on May 1, 2000, when a satellite system developed by the U.S. Department of Defense was made public. Using an inexpensive GPS device, anyone on earth can send a signal to the satellites and receive information about their position. This is basically a high-tech version of orienteering, the traditional pastime which uses maps and compasses instead of GPS to determine one’s location.
Geocachers are a very considerate group. Owners carefully choose a cache’s location to give finders an enjoyable experience, such as a beautiful view or a good campsite. They also consider the environmental impact of their cache since it could result in an increased number of visitors to an area. As for the content of the caches, owners and finders must only use items that are suitable for the whole family, as caches are found by geocachers of all ages.
28. According to the passage, geocaching is __________.
A. an outdoor leisure activity B. a new type of technology
C. a game used to teach geography D. a program to protect environment
29. How can finders learn about the cache owners?
A. By meeting them. B. By going to a website.
C. From the notebook. D. From the satellite.
30. Which of the following is NOT used in geocaching?
A. A GPS device. B. A compass. C. A plastic container. D. The Internet.
31. Which of the following is true according to the passage?
A. Most geocachers are adults.
B. Any item can be placed in the caches.
C. The caches should be put in a remote place.
D. Geocachers try to avoid damaging the environment.
