Often these people were unable to read and hadn’t enough time to learn. In any case, the books were so big that it was difficult for anyone to relax with a book as we do today. They wanted booked because they were expensive and there was something magical about them. Only a few people were able to write, and it took an extremely long time to write a book. Monks and other people who could write said ordinary people could not learn to read.

The position with computers is very similar today. A few years ago, computers were very large and expensive. Business managers and rich people ordered them but they didn’t know how to use them. In many countries, however, the situation has now completely changed. Lots of people not only own microcomputer but also know how to use them.

Read the following passage, translate and write T (for TRUE) and F (for FALSE).

Like most other hobbies, stamp colleting can be exhilarating, time-consuming and, for the uninitiated, overwhelming. Consider this - it is estimated that in the last 100 years alone, close to one billion diffrent stamps have been issued by governments all around the world. Not only that, but some of these stamps are as rare, and as expensive, as Renaissance paintings. The most famous is probably the upside-down airplane stamp, valued at almost 1 million dollars. Also the result of a printing mistake is the world's most expensive stamp, the Treskilling Yellow, so called because it was originally worth three shillings when issued in Sweden in 1855, and because it was supposed to be printed in green, this being the only known sample in yellow. This stamp was recently sold at auction for 1.7 milion pounds, making it the single most expensive item by weight in the world. Of course, amateur philatelists would do well to concentrate on a sub-section of the wonderful world that is philately, such as collecting every stamp issued by a certain government in a year, or collecting every stamp of a particular design, etc. Any other approach to this hobby is a sure fire recipe for frustration and perhaps for ruin.
