Text 2Some 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 Englishman is keen on working with his 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 builders’ and decorators’ costs have reached a level which makes them so high that house - proud English people of modest means hang back. So, if they wish to keep their houses looking bright and smart, they have to deal with 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. A number of magazines and handbooks exist to show hopeful handymen of all ages just how easy it is to build anything from a coffee table to a fifteen -foot(4.5 meters) sailing boat. All you need, it seems, is a hammer and a few nails. You follow the simple instructions step - by - step and, before you know where you are, the finished article stands before you, complete in every. detail.Unfortunately, alas, it is not always quite as simple as it sounds ! Many a ’ do - it - yourselfer’ has found to his cost that one cannot learn a skilled craftsman’ s job overnight. How quickly one realizes, when doing it oneself, that a job which takes the skilled man an hour or so to complete takes the amateur five or six at least. And then there is the question of tools. The first thing the amateur learns is that he must have the right tools for the job. Bui tools cost money. There is also the wear and tear on the nerves. It is not surprising then that many people have come to the conclusion that the expense of paying professionals to do the work is, in the long run, more economical than ’ doing it oneself’. As an amateur, you' ll have to()first.

A. follow the instructions in magazines
B. get the right tools
C. prepare fully psychologically
D. ask a skilled craftsman' s advice
