Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the
correct answer to each of the questions from 41 to 45.
A good deal of fascinating research has been done about the reading patterns of young people, and it is
surprising to discover at what an early age children start expressing preferences for particular kind of books.
A recent report, which examined in detail the reading habits of primary-school children showed that even
seven-year-old boys and girls have clear views about what they want to read. Girls, in general, read more, and
far more girls than boys preferred reading stories. Boys were showing a taste for the more instant appeal of
picture stories, or else books about their hobbies.
These tastes continue unchanged until the children are teenagers. Apparently girls read more in general,
but more fiction in particular .You could say that there are more opportunities for girls to read fiction:
magazines encourage the fiction habit in girls in their early teens, and by their late teens they have probably
moved on to the adult women’s magazines. Teenage boys tend to buy magazines about their hobbies:
motorcycles, heavy transport and to on.
Adult reading tastes are also the subject of research. Again the number of women who read for pleasure
is considerably higher than the number of men. It seems that the majority of women still want love stories.
There has also been some analysis of what men actually read. Apparently only 38 percent of men read
anything, but 50 percent of what they read is fiction in the form of action-packed stories of space or gunmen.
Question 41: The recent research into children’s reading has shown that they _______.
A. begin to read very fast at an early age.
B. examine in detail what they read at school.
C. can read clearly in primary school.
D. form their reading tastes by the time they are seven.
Question 42: If we have a close look at the reading habits of boys and girls we’ll find that ______.
A. schools give more encouragement to girls than to boys.
B. girls are more interested in fiction than boys.
C. picture stories appeal more to girls than boys.
D. magazines appeal more to boys than girls.
Question 43: According to the passage, _______.
A. children generally don’t care what they should read.
B. far more boys than girls are interested in love stories.
C. teenage boys show a taste for magazines about their hobbies.
D. there are more opportunities for girls to buy magazines than for men.
Question 44: It can be inferred from the passage that_________
A. people have no definite reading tastes.
B. boys change their reading tastes more often than girls.
C. boys and girls form their reading habits by reading magazines.
D. people usually do not change their reading tastes when they grow up.
Question 45: The word “fascinating” in line 1 means most nearly the same as _______.
Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the
correct answer to each of the questions from 46 to 50.
Until recently, humankind seemed to view the ocean as a source of infinite resources. Its vast size and
depth and unexplored frontiers made the ocean appear invulnerable to overexploitation. The truth is that the
populations of many species are decreasing at an unsustainable rate, and the number of species listed as
endangered from marine life families such as whales, dolphins, manatees and dugongs, salmon, seabirds, sea
turtles, and sharks to name a few, are on the rise. The threats to marine species are difficult to perceive
because marine animals are not as visible as animals on land. But unfortunately, marine creatures are equally,
if not more, vulnerable to problems such as habitat destruction and overexploitation. Shallow water animals
that breathe air, like turtles, manatees, dugongs, and whales are often hit by boats and caught in fishing gear.
Species such as turtles that lay their eggs on land often lose their nurseries due to coastal development.
Animals that have taken millions of years to evolve, that are invaluable to all ecosystems, have and continue
to vanish from places where they once flourished.
Question 46: What is human’s perception of the ocean so far?
A. The ocean resources will never be exhausted.
B. The ocean is capable of resisting overexploitation.
C. Both A & B are correct.
D. Neither of A & B is correct.
Question 47: All of the following are true EXCEPT ______.
A. Turtles are a kind of shallow water animal.
B. The evolution of animals could take up to millions of years.
C. Powerful animals like sharks run less risk of endangerment.
D. Coastal development affects the reproduction process of some sea animals.
Question 48: Which of the followings is closest in meaning to “vulnerable”?
A. Weak
B. Resistant
C. Energetic
D. Adaptive
Question 49: What is the reason for the difficulty in understanding threats to marine life?
A. That technology is underdeveloped.
B. That humans can hardly see marine creatures.
C. That the rate of population decrease is unsustainable.
D. That there are too many types of marine creatures in the ocean.
Question 50: What does “flourished” in the passage mean?
