[问答题]Practice 7　　Some people would say that the Englishman's home is no longer his castle; that it has become his workshop. This is partly because the average English is keen on working with his own hands and partly because he feels, for one reason or another, that he must do for himself many household jobs for which, some years ago, he would have hired professional help. The main reason for this is a financial one.. the high cost of labor has meant that the builders and decorators' costs have reached a level which makes them prohibitive for house-proud English people of modest means. So, if they wish to keep their houses looking bright and smart, they have to tackle some of the repairs and decorating themselves. As a result, there has grown up in the post-war years what is sometimes referred to as the “Do-it-yourself Movement”.　　The “Do-it-yourself Movement” began with home decorating but has since spread into a much wider field. Nowadays there seem to be very few things that cannot be made by the “do-it- yourself” method.
