In most countries, a direct tax on persons, 【57】is called income tax, exists. It is arranged in【58】a way that the poorest people pay nothing, and the【59】of tax grows greater as the taxpayers'【60】grows. In England, for example, the tax on the【61】people goes up as【62】as ninety-five percent!
But countries with direct taxation nearly always have【63】taxation too. Many things【64】into the country have to pay taxes or "duties".【65】, it is the men and women who buy these imported things in the shops who really have to pay the duties, in the【66】of higher prices. In some countries, too, there is a tax on things sold in the shops. If the most necessary things are taxed, a lot of money is collected, but the poor people suffer【67】If unnecessary things like jewels and fur coats are taxed, 【68】money is obtained, but the tax is fairer, as the【69】pay it.
Probably this last kind of indirect tax, 【70】with a direct tax on incomes which is low for the poor and high for the rich, is the best arrangement.

To squeeze the most out of each shining hour we have shortened the opera, quickened the pace of the movie and put culture in pocket-sized packages. We make the busy bee look like a lazy creature, the ant like a sluggard. We live sixty-mile-minute and the great efficiency smiles.
We wish we could return to that pleasant day when we considered time a friend instead of an enemy; when we did things willingly and because we wanted to, rather than because our timetable called for it, But that of course would not be efficiency; and we Americans must be efficient.
The phrase that best expresses the main idea of this passage is ______. ()
A.the modern pace
B.our interest in shortened operas
C.how to make the best use of leisure time
D.planning our time scientifically
A book to be published in Britain this week, The End of Science, argues persuasively that this is the case. Its author, John Horgan, is a senior writer for Scientific American magazine, who has interviewed many of today's leading scientists and science philosophers. The shock of realizing that science might be over came to him, he says, when he was talking to Oxford mathematician and physicist Sir Roger Penrose.
The End of Science provoked a wave of denunciation in the United States last year. "The reaction has been one of complete shock and disbelief, "Mr. Horgan says.
The real question is whether any remaining unsolved problems, of which there are plenty, lend themselves to universal solutions. If they do not, then the focus of scientific discovery is already narrowing. Since the triumphs of the 1960s—the genetic code, plate tectonics, and the microwave background radiation that went a long way towards proving the Big Bang—genuine scientific revolutions have been scarce. More scientists are now alive, spending more money on research, that ever. Yet most of the great discoveries of the 19th and 20th centuries were made before the appearance of state sponsorship, when the scientific enterprise was a fraction of its present size.
Were the scientists who made these discoveries brighter than today's? That seems unlikely. A far more reasonable explanation is that fundamental science has already entered a period of diminished returns. "Look, don't get me wrong," says Mr Horgan. "There are lots of important things still to study, and applied science and engineering can go on for ever. I hope we get a cure for cancer, and for mental disease, though there are few real signs of progress."

C.there have never been so many best things waiting to be discovered

A.He is most likely to refuse to absorb the strange environment at first.

C.Although he takes the culture difference for granted, he still doesn't know how to do with it.
D.He may begin to hate the people or things around him.
