Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to the following questions.

Sound moves form its source to the ear by wavelike fluctuations in air pressure, something like the crests and troughs of ocean waves. Once way to keep from hearing sound is to use ear plugs. Another way is to cancel out the sound with anti-sound. Using a noisemarker controlled by a microprocessor, engineers have produced sound waves that are half a wavelength out of phase with those of the noise to be quieted-each crest is matched to a trough, and vice versa. Once the researchers have recorded the offending sound, a microprocessor calculates the amplitude and wavelength of sound that will cancel out the crests and troughs of noise. It then produces an electric current that is amplified and fed to a loudspeaker, which produces anti-sound and wipes out the noise. If the anti-sound goes out of synchronization, a microphone picks up the leftover sound and sends it back to the microprocessor, which changes the phase of the anti- sound just enough to cause complete silence.

The research team has concentrated on eliminating low-frequency noise from ship engines, which causes fatigue that can impair the efficiency and alertness of the crew, and may mask the warning sounds of alarm and fog signals.

A paragraph following the passage would most probably discuss_________.

A. the nature of fog 

B. a way to improve alarm systems 

C. other causes of fatigue

Câu 28. 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.

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 listed as endangered from marine life families such as whales, dolphins, manatees and dugongs, salmon, seabirds, sea turtles, and sharks to name a few, is 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 invulnerable to all ecosystems, have and continue to vanish from places where they once flourished.

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 and B are correct

D. Neither A nor B is correct.

Câu 29. All of the following are true EXCEPT ____________.

A. turtles are a kind of shallow water animal

B. the evolution of some animals could take up to millions of years

C. powerful animals like sharks run less risk of endangerment

D. coastal development affects the reproductions process of some sea animals

Câu 30. Which of the following is closest in meaning to “vulnerable”?

A. resistant B. energetic C. weak D. adaptive

Câu 31. What is he reason for the difficulty in understanding threats to marine life?

A. That humans can hardly see marine creatures.

B. That the rate of population decrease is unsustainable.

C. That technology is underdeveloped.

D. That there are too many types of marine creatures in the ocean.

Câu 32. What does “flourished” mean?

A. changed into something unusual B. failed miserably

C. spread all over D. grew in a successful way

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, is 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.
