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 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. But 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'.

听力原文： In the near future diagnosing a patient's illness may become much less painful for the patient and less uncertain for the doctor. Research and technological advances in scientific photography may ultimately enable a doctor to discover a patient's problem with pictures rather than with blood and tissue samples. Such new diagnostic techniques may even help doctors detect diseases much earlier than they could by using conventional techniques. One new technique is thermography, a photographic process in which variations in temperature within the body show up as different colors. Even at rest, the temperatures of different areas of the body are constantly changing. Scientists are now trying to understand why this is true and how these variations in temperature relate to illness. Although the research is incomplete, most scientists agreed that thermography holds definite possibilities for early detection of disease or for predicting individual's predisposition for certain unhealthy conditions. This technique of measuring the variation of body temperature graphically has a great advantage over X rays and other conventional diagnostic methods. With thermography, there are no side-effects, no uncomfortable exploratory procedures and there's no need to take blood and tissue samples. Patients need not to endure pain or fear unknown procedures. There's no question that this new photographic technique will improve health care in the future.
