In the past hundred years, the world’s attitude toward whales has changed a lot. The animals are no longer seen as frightening creatures and worldwide protection efforts have reduced whale hunting. Through careful observation, scientists have shown that whales are generally peaceful, playful creatures, and that they have a high level of intelligence.
But even now, some behaviour of whales is still a mystery. A lot of information gathered by whale researchers has raised new puzzles about the animals. Whales’ communication is particularly difficult to understand. Male humpbacks (also known as bulls) give off a sequence (一连串) of low moans(呻吟), high screams and clicking noises. These noises are sometimes combined in songs that last as long as 30 minutes. And in a particular region, every male will sing the same song, making small changes every once in a while so that it evolves (逐渐形成) into a completely different song over time.
This behavior seems to be related to reproduction. During the mating (交配) season, a male humpback starts the long song sequence, stopping only to join a passing female whale (also known as a cow). Eventually, the bull and the cow may dive deep into the ocean, probably to mate. Male humpbacks’ songs are similar to what birds display to attract mates (配偶), except that the sound carries over many miles, attracting some other male humpbacks in the area. It’s very odd that a male would call his own competition to him, unless he actually wanted to test his strength against others. Some whale researchers believe that the songs are actually acoustic (听觉的) contests of strength.
1.What can we infer from the first paragraph?
A. We used to have wrong ideas about whales.
B. Whales are in danger of dying out today.
C. Whales have always been considered as fierce creatures.
D. Whales are only protected in some parts of the world.
2.We can learn from the second paragraph that .
A. male whales and female whales both sing songs
B. people can’t fully understand whales’ communication
C. people only understand the songs of male whales
D. the songs of male whales never change
3.The last paragraph suggests that male humpbacks sing songs most probably to .
A. find their own family members
B. work together with others to hunt
C. compete against other male humpbacks
D. frighten away other male humpbacks

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.

Every year there are hundreds of earthquakes in different parts of the world. In Sept.1923, Tokyo and Yokohama were both destroyed by an earthquake and the fires that followed it. They had to be completely rebuilt. One of the most serious earthquakes was in China’s Shanxi Province in 1556. It killed almost one million people.
We measure an earthquake’s strength on the Richter scale. The Richter scale was introduced in 1935 in Southern California in the USA. It measures earthquakes on a scale of one to ten. Any earthquake measuring five or more is usually serious.
The earth’s crust (地壳) is made up of layers of rock called plates. As these plates move, they sometimes crash against each other, causing the crust to quake. In cities such as Tokyo, where small quakes happen quite often, many modern buildings are designed to be flexible so when the earth moves, they move with it.
Earthquakes can also break up gas or oil pipes. This can cause fires to break out, which can do as much damage as the earthquake itself.
Another effect of earthquakes is tsunamis (海啸). These are huge waves created by earthquakes beneath the sea. They can be many meters high and cause great damage to coastal towns and cities.
China, Japan, Russia and the USA have the highest occurrence (发生) of earthquakes in the world.
