(1)Some people believe that international sport creates goodwill between the nations and that if countries play games together they will learn to live together.Others say that the opposite is true: that international contests encourage false national pride and lead to misunderstanding and hatred. (2)There is probably some truth in both arguments, but in recent years the Olympic Games have done little to support the view that sports encourages international brotherhood.(3)Not only was there the tragic incident involving the murder of athletes, but the Games were also ruined by lesser incidents caused principally by minor national contests.

One country received its second-place medals with visible indignation after the hockey final. (4)There had been noisy scenes at the end of the hockey match, the losers objecting to the final decisions.(5)They were convinced that one of their goals should not have been disallowed and that their opponents' victory was unfair.Their manager was in a rage when he said: "This wasn't hockey. Hockey and the International Hockey Federation are finished". The president of the Federation said later that such behavior could result in the suspension of the team for at least three years.

判断正误：Reporting sales figures

After a slow start at the beginning of the year when sales started out at $ 9 million and rose to $ 10 million for the month of January, there was a slight increase in February when sales went up to $ 14. 5m. Then in March we had a dramatic increase when sates shot up to a staggering $ 34m. This was after the big Trade Fair in Hong Kong, where we managed to promote our new products and capturé the SE Asin market: The-increase continued in April when sales peaked at $ 38. 5m. There was slight fall for the month of May, which was only to be expected after the rush of interest after Hong Kong, and figures hit the $ 30m. mark. They seem to stabilise there, as the June figures were much the same at $ 31. 4m. We have every to expect them to continue at this rate for the next few munths, but our target for the end of the year is to chase the $ 40m+ mark with a very aggressive marketing policy over the summer and the autumn.

16. The product under discussion is not stated.

17. The year started with a rush.

18. January saw a decline in sales.

19. In February sales declined slightly.

20. In March sales reached $34m.

21. The Hong Kong Trade Fair made little effect on sales.

22. In May the sales figures exceeded those of March.

23. The June figures were similar to the May figures.

24. If the business reaches $ 40 +, the target for the end of the year will have been reached.

25. There would be more ups than down in a chart of the January to June' figures.

On nothing per annum, then, and during a course of some two or three years, of which we ca

n afford to give but a very brief history, Crawley and his wife lived very happily and comfortably at Paris. It was in this period that he quitted the Guards, and sold out of the army. When we find him again, his mustachios and the title of Colonel on his card are the only relics of his military profession. It has been mentioned that Rebecca, soon after her arrival in Paris, took a very smart and leading position in the society of that capital, and was welcomed at some of the most distinguished houses of the restored French nobility. The English men of fashion in Paris courted her, too, to the disgust of the ladies their wives, who could not bear the parvenue. For some months the salons of the Faubourg St. Germain, in which her place was secured, and the splendours of the new Court, where she was received with much distinction, delighted, and perhaps a little intoxicated Mrs. Crawley, who may have been disposed during this period of elation to slight the people-honest young military men mostly-who formed her husband s chief society. But the Colonel yawned sadly among the Duchesses and great ladies of the Court. The old women who played ecart6 made such a noise about a five-franc piece, that it was not worth Colonel Crawley s while to sit down at a card-table. The wit of their conversation he could not appreciate, being ignorant of their language. And what good could his wife get, he urged, by making curtsies every night to a whole circle of Princesses？ He left Rebecca presently to frequent these parties alone; resuming his own simple pursuits and amusements amongst the amiable friends of his own choice. The truth is, when we say of a gentleman that he lives elegantly on nothing a year, we use the word "nothing" to signify something unknown, meaning, simply, that we dont know how the gentleman in question defrays the expenses of his establishment. Questions:

This passage is taken from a famous novel entitled______.
