Laziness is a sin，everyone knows that. We have probably all had lectures pointing out that laziness is immoral, that it is wasteful, and that lazy people will never amount to anything in life. But laziness can be more harmful than that, and it is often caused by more complex reasons than simple wish to avoid work. Some people who appear to be lazy are suffering from much more serious problems. They may be so distrustful of their fellow workers that they are unable to join in any group task for fear of ridicule or fear of having their ideas stolen. These people who seem lazy may be paralyzed by a fear of failure that prevents fruitful work. Or other sorts of fantasies may prevent work; some people are so busy planning, sometimes planning great deals or fantastic achievements that they are unable to deal with whatever "lesser" work is on hand. Still other people are not avoiding work; strictly speaking, they are merely procrastinating-rescheduling their day.

Laziness can actually be helpful. Like procrastinators, some people may look lazy when they are really thinking, planning, contemplating, researching. We should all remember that great scientific discoveries occurred by chance. Newton wasn't working in the orchard when the apple hit him and he devised the theory of gravity. All of us would like to have someone "lazy"were caused by the worker's taking time to check each step of his work and to do his job right. And sometimes, being lazy that is, taking time off for a rest is good for the overworked students or executive.

Taking a rest can be particularly helpful to the athlete who is trying too hard or the doctor who's simply working himself overtime too many evenings at the clinic. So be careful when you' re tempted to call someone lazy. That person may be thinking, resting, and planning his or her next book.

The main idea of this passage is that_______.

As used in the passage，the word“devised”（Sentence 4，Para 2）means.

As regards social conventions，we must say a word about the wel-known English class system. This is an  embarassing  subject for English people，and one they tend to be ashamed of，though during the present century class-consciousness has grown less and less，and the class system less rigid. But it still exists below the surface. Broadly speaking，it means there are two clases，the"middle class"and the"working class”.（We shall ignore for a moment the old“upper class"，including the hereditary aristocracy，since it is extremely small in numbers；but some of its members have the right to sit in the House of Lords，and some newspapers take surprising interest in their private life.）The middle class consists chiefly of well-to-do businessmen and professional people of all kinds. The working class consists chiefly of manual and unskilled workers.

The most obvious difference between them is in their accent. Middle-class people use slightly varying kinds of"received pronunciation"which is the kind of English spoken by BBC announcers and taught to overseas pupils. Typical working-class people speak in many different local accents which are generally felt to be rather ugly and uneducated. One of the biggest barriers of social equality in England is the two-class education system. To have been to a so-called "public school"immediately marks you out as one of the middle class. The middle classes tend to live a more formal life than working-class people, and are usually more cultured. Their midday meal is "lunch"and they have a rather formal evening meal called "dinner", whereas the working man's dinner, if his working hours permit, is at midday, and his smaller, late-evening meal is called supper.

As we have said, however, the class system is much less rigid than it was, and for a long time it has been government policy to reduce class distinctions. Working-class students very commonly receive a university education and enter the professions, and working-class incomes have grown so much recently that the distinctions between the two classes are becoming less and less clear. However, regardless of one's social status, certain standards of politeness are expected of everybody, and a well-bred person is polite to everyone he meets, and treats a laborer with the same respect he gives an important businessman. Servility inspires both embarrassment and dislike. Even the word"sir", except in school and in certain occupations(e.g. commerce, the army, etc.) sounds too servile to be commonly used.

The middle class mainly refers to people_______.
