?.????? ??????,???????????,????????? A Australia,
the last continent, was discovered by ships
belonging to some European nations in the
seventeenth century.These nations were less
interested in changing it into a colony than in
exploring it.As in the early history of the
United States, it was the English who set up the
settlements in Australia.This history and the
geography of these two British colonies have some
other things in common as well. 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.
10
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
11
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(??) 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.
13
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

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
