It is hard to track the blue whale, the ocean’s largest creature, which has almost been killed off by commercial whaling and is now listed as an endangered species. Attaching radio devices to it is difficult, and visual sightings are too unreliable to give real insight into its behavior.
So biologists were delighted early this year when, with the help of the Navy, they were able to track a particular blue whale for 43 days, monitoring its sounds. This was possible because of the Navy’s formerly top-secret system of underwater listening devices spanning the oceans.
Tracking whales is but one example of an exciting new world just opening to civilian scientists after the cold war as the Navy starts to share and partly uncover its global network of underwater listening system built over the decades to track the ships of potential enemies.
Earth scientists announced at a news conference recently that they had used the system for closely monitoring a deep-sea volcanic eruption （爆发） for the first time and that they plan similar studies.
Other scientists have proposed to use the network for tracking ocean currents and measuring changes in ocean and global temperatures.
The speed of sound in water is roughly one mile a second—slower than through land but faster than through air. What is most important, different layers of ocean water can act as channels for sounds, focusing them in the same way a stethoscope （听诊器） does when it carries faint noises from a patient’s chest to a doctor’s ear. This focusing is the main reason that even relatively weak sounds in the ocean, especially low-frequency ones, can often travel thousands of miles.
1.The passage is chiefly about ____ .
A. an effort to protect an endangered marine species
B. the civilian use of a military detection system
C. the exposure of a U.S. Navy top-secret weapon
D. a new way to look into the behavior of blue whales
2.The underwater listening system was originally designed ____ .
A. to trace and locate enemy vessels
B. to monitor deep-sea volcanic eruptions
C. to study the movement of ocean currents
D. to replace the global radio communications network
3.The deep-sea listening system makes use of ____ .
A. the sophisticated technology of focusing sounds under water
B. the capability of sound to travel at high speed
C. the unique property of layers of ocean water in transmitting sound
D. low-frequency sounds travelling across different layers of water____
4.It can be inferred from the passage that____.
A. new radio devices should be developed for tracking the endangered blue whales
B. blue whales are no longer endangered with the use of the new listening system
C. opinions differ as to whether civilian scientists should be allowed to use military technology
D. military technology has great potential in civilian use
5.Which of the following is true about the U.S. Navy underwater listening network?
A. It is now partly accessible to civilian scientists.
B. It has been replaced by a more advanced system.
C. It became useless to the military after the cold war.
D. It is indispensable in protecting endangered species.

From July to October every year, about a quarter of the world’s blue whales feed in the Pacific Ocean off the coast of California. But the whales currently face a major threat in their favorite feeding area. Ships carrying cargo (货物）sail in the same area at the same time. All too often, the whales’ paths and the ships’ travel lines overlap (重叠), and a ship will hit a whale.
According to a new study, these ship strikes have become a serious threat to the overall population of the world’s blue whales. Only about 10,000 of the creatures still exist worldwide. Blue whales are the largest known animals ever to live on Earth. Even so, if hit by a container ship, a blue whale will likely die from its injuries.
In 2007 alone, large ships killed five blue whales in the waters off San Francisco and Los Angeles, California. The National Oceanic and Atmospheric Administration (NOAA) says that because there are so few whales already, losing three to five from the California whale population every year is a significant loss. “The estimated population of blue whales in this part of the Pacific is 2,500”, says Sean Hastings, a NOAA analyst. “So every whale counts toward this species moving off the endangered-species list.”
Now, marine scientists must figure out how to protect the whales from the giant container ships. One very simple program is already under way in the Santa Barbara Channel, a waterway that separates mainland California from the nearby Channel Islands.
The Channel Islands National Marine Sanctuary has asked large container ships passing through the area to voluntarily slow down. Sailing slower will allow the ships‟ crew (船员）more time to change course before hitting a whale.
Several of the world’s largest shipping lines are set to participate in the new program. For every ship that passes through the Santa Barbara Channel at or below the reduced speed of 12 knots (海里/小时）, the company that owns the ship will be paid $2,500.
1.From Paragraph 1, we can know that_____.
A. people intend to illegally hunt blue whales for money
B. large ships often carrying goods may pollute the sea
C. the container ships may hit the blue whales frequently
D. there is fewer fish in blue whales‟ favorite feeding area
2.Why is the death of several whales regarded as significant loss to the world's blue whales?
A. Because the number of the blue whales is so small.
B. Because other blue whales will be scared away.
C. Because blue whales are the largest animals in the world.
D. Because many blue whales get killed throughout the year.
3.According to Sean Hastings, it’s inferred that .
A. the number of the blue whales is decreasing sharply.
B. the blue whales are still on the endangered-species list.
C. most of the world’s blue whales live in the Pacific Ocean.
D. blue whales are often disturbed by other endangered creatures.
4.What are the last three paragraphs mainly about?
A. The basic responsibility of a sailor.
B. Measures to protect the blue whales.
C. The world’s largest shipping lines.
D. Ways to slow down the speed of the ships.

What do you want to be when you grow up? A teacher? A doctor? How about an ice-cream taster?
Yes, there really is a job where you can get paid to taste ice cream. Just ask John Harrison, an “Official Taste Tester” for the past 21 years. Testing helps manufacturers to be sure of a product’s quality. During his career Harrison has been responsible for approving large quantities of the sweet ice cream—as well as for developing over 75 flavors（味道）.
Some people think that it would be easy to do this job; after all, you just have to like ice cream, right? No—there’s more to the job than that, says Harrison, who has a degree in chemistry. He points out that a dairy or food-science degree would be very useful to someone wanting a career in this “cool” field.
In a typical morning on the job, Harrison tastes and assesses 60 ice-cream samples. He lets the ice cream warm up to about 12°F. Harrison explains, “You get more flavor from warmer ice cream, which is why some kids like to stir（搅拌）it, creating ice-cream soup.”
While the ice cream warms up, Harrison looks over the samples and grades each one on its appearance. “Tasting begins with the eyes,” he explains. He checks to see if the ice cream is attractive and asks himself，“Does the product have the color expected from that flavor?” Next it’s time to taste!
Continuing to think up new ideas, try out new flavors, and test samples from so many kinds of ice cream each day keeps Harrison busy but happy – working at one cool job.
1. What is John Harrison’s job?
A. An official. B. An ice-cream manufacturer.
C. A chemist. D. An ice-cream taster.
2.According to John Harrison, to be qualified in the “cool field”, it is helpful to ________.
A. think up new ideas every day
B. keep a diary of daily work
C. have a degree in related subjects
D. find out new flavors each day
3.What does Harrison do first when testing ice cream?
A. He stirs the ice cream.
B. He lets the ice cream warm up.
C. He tastes the flavor of the ice cream.
D. He examines the color of the ice cream.
4.Which of the following is probably the best title for the passage?
A. One Cool Job B. Flavors of Ice Cream
C. Tasting with Eyes D. John Harrison’s Life
