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.

So the little girl now walked on, her bare feet quite red and blue with the cold. She carried a small bundle of matches in her hand, and a good many more in her tattered dress. No one had bought any of them the live long day； no one had given her a single penny. Trembling with cold and hunger crept she on, the picture of sorrow: poor little child!

The snow-flakes fell on her long, fair hair, which curled in such pretty ringlets over her shoulders; but she thought not of her own beauty, or of the cold. Lights were glimmering through every window, and the savor of roast goose reached her from several houses；it was New Year's eve, and it was of this that she thought.

In a corner formed by two houses, one of which projected beyond the other. She sat down, drawing her little feet close under her, but in vain, she could not warm them. She dared not go home, she had sold no matches, earned not a single penny, and perhaps her father would beat her，besides her home was almost as cold as the street，it was an attic; and although the larger of the many chinks in the roof were stopped up with straw and rags. The wind and snow often penetrated through. Her hands were nearly dead with cold; one little match from her bundle would warm them. Perhaps, if she dared light it, she drew one out, and struck it against the wall, bravo! It was a bright, warm flame, and she held her hands over it. It was quite an illumination for that poor little girl; no, I call it rather a magic taper, for it seemed to her as though she was sitting before a large iron-stove with brass ornaments, so beautifully blazed the fire within! The child stretched out her feet to warm them also; alas, in an instant the flame had died away, the stove disappeared, the little girl sat cold and comfortless, with the burnt match in her hand.

1.The author emphasized that the story happened on New Year’s Eve in order to _________.

A. highlight the cold weather

B. contrast with the girl’s sadness.

C. present the time

D. describe the situation

2.Which below is not the reason why the little girl dared not go home?

A. She earned not a single penny.

B. Her father would beat her.

C. Her home was almost as cold as the street.

D. She didn’t finished selling her matches.

3.The underlined sentence in the last paragraph told us ___________.

A. the girl was so cold that she formed an illusion that she sat beside a stove

B. a stove did give her some warmth on such a cold night

C. the thought she had could give her warmth

D. the light the match gave out did warm the little girl

4.The little girl gave us an impression of being __________.

A. beautiful and kind　　　　　　　　　 B. poor but imaginable　

C. poor and pitiful　　　　　　　　　　 D. poor but lively

高二英语完形填空中等难度题查看答案及解析

It’s hard to track the blue whale, which has almost been killed off by commercial whaling. 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 US Navy, they are able to track a particular blue whale for 43 days recording its sounds. This was possible because of the Navy’s former top secret system of underwater listening devices across 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 observing a deep-sea volcanic eruption for the first time and that they planned similar studies. Other scientists have proposed to use the network for tracking ocean currents and measuring changes in the ocean and global temperatures. 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 underwater listening system was originally designed _________________.

A. to trace and locate enemy ships

B. to observe deep sea volcanic eruptions

C. to study the movement of ocean currents

D. to replace the global radio communications network

2.The deep-sea listening system makes use of __________________.

A. the ability of sound to travel at high speed

B. the top-level technology of focusing sounds under water

C. the unique characteristic of layers of ocean water in carrying sound

D. low-frequency sounds traveling across different layers of water

3.What can we infer from the passage?

A. New radio devices are developed for tracking the blue whales.

B. Blue whales are no longer endangered with the new system.

C. Opinions differ on the use of military technology.

D. Military technology has great potential in civilian use.

4.What is the passage 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 US Navy top-secret weapon.

D. A new way to look into the behavior of blue whales.

Do’s and Don’ts in Whale(鲸) Watching

The Department of Fisheries and Oceans has developed guidelines for whale watching in Johnstone Strait, where killer whales are found on a daily basis each summer. It is strongly recommended that vessel(船只) operators follow these guidelines for all kinds of whales.

· Approach whales from the side, not from the front or the back.

· Approach no closer than 100 metres, then stop the boat but keep the engine on.

· Keep noise levels down — no horns, whistles or racing of engines.

· Start your boat only after the whales are more than 100 metres from your vessel.

· Leave the area slowly, gradually moving faster when you are more than 300 metres from the whales.

· Approach and leave slowly, avoiding sudden changes in speed or direction.

· Avoid disturbing groups of resting whales.

· Keep at low speeds and remain in the same direction if traveling side by side with whales.

· When whales are traveling close to shore, avoid crowding them near the shore or coming between the whales and the shore.

· Limit the time spent with any group of whales to less than 30 minutes at a time when within 100 to 200 metres of whales.

· If there is more than one vessel at the same observation spot, be sure to avoid any boat position that would result in surrounding the whales.
