Australia and the United States are about the same in size, and their western lands are both not rich in soil．It was the eastern coast of Australia and America that the English first settled, and both colonies soon began to develop towards the west．However, this westward movement took place more because the English were searching for better land than because the population was increasing．Settlements of the western part of both countries developed quickly after gold was discovered in America in 1849 and in Australia two years later. Although the development of these two countries has a lot in common, there are some striking differences as well．The United States gained its independence from England by revolution while Australia won its independence without having to go to war．Australia, unlike the United States, was firstly turned into a colony by English prisoners and its economic development was in wheat growing and sheep raising．By 1922, for example,Australia had fifteen times more sheep than it had people, or almost half as many sheep as there are people today in the United States．Yet, in spite of these and other main differences, Australia and the United States have more in common with each other than either one has with most of the rest of the world． 51．Who turned Australia into a colony? A．Britain. B．Several European countries． C．The United States of America. D．None of the above． 52．In the early history of America and Australia, both colonies developed towards the west firstly for the reason that ______． A．the population was increasing rapidly in the east B．the English thought there might be richer land there C．gold was discovered there D．fewer people lived there 53．In the early 1920s, ______． A．Australia had one fifteenth as many people as sheep B．there were more sheep in Australia than in the United States C．the population in Australia was greater than that of the United States D．the United States had twice as many sheep as people 54．Australia, unlike the United States, ______． A．won its independence by peaceful means B．did not discover gold until the late 1840s C．was the last and biggest continent to be discovered D．was not rich in gold in its western part 55．The last sentence in the last paragraph “…Australia and the United States have more in common with each other than either one has with most of the rest of the world” means “ ______ ”． A．The United States and Australia do not have any main differences B．The United States and Australia have much more in common than they have with other countries C．The United States and Australia have nothing in common with the rest of the world D．In common with the rest of the world, the United States and Australia have a lot of differences B “What we want is rest, ” said Harris． “Rest and a complete change, ” said George．“Change of scene, and no need to think about anything．” I agreed with George, and suggested we should look for some quiet place far from crowds and the noisy world． Harris said he thought it would be terrible．He said he knew the kind of place I meant; where everybody went to bed at eight o'clock, and you couldn't get an Evening News for love or money, and had to walk ten miles to the nearest cinema．“No,” he said, “if you want rest and a change, you had better take a sea trip．” I was strongly against a sea trip．A sea trip does you good when you are going to have a couple of months of it, but for a week, it is pointless． George said, “Let's go up the river．” He said we should have fresh air and rest, the constant change of scene would broaden our minds, and the hard work would give us a good appetite(食欲) and make us sleep well． Harris said he didn't think George ought to do anything that might make him sleepier than he already was, but all the same he agreed the river would suit him, Harris, perfectly．It suited me too and we therefore decided to go up the river． 56．George's idea of rest and a complete change is ______． A．having nothing on his mind B．not having any worries in life C．relaxing in new places D．not thinking about new scenes 57．When Harris said, “You couldn't get an Evening News for love or money”, he meant you couldn't get a paper ______． A．by any means B．for its selling price C．to read about love or money D．as a kindness 58．When Harris also said, “One had to walk ten miles to the nearest cinema”, he meant ______． A．there was no cinema ten miles round B．the nearest cinema was about ten miles away C．the nearest cinema was too far away for him D．there wasn't a cinema even ten miles away 59．When the writer said it was pointless to go on a sea trip for a week, he meant ______． A．it was a pleasure to have nothing to do for a week B．a week was too short C．it was better than going for two months D．you did not go to a certain place 60．The hard work would give them a good appetite because ______． A．they would eat a lot B．they would drink a lot C．it would make them sleep well D．it would make them hungry
