??? When the cathedral of Notre Dame de Paris (巴黎圣母院) was on fire, it seemed as if the nation had lost a piece of its soul. A similar tragedy took place in 19th century Russia. And the rebuilding effort of the Russians might offer some inspiration for the French.

Standing in the heart of the Russian capital, with 60,000 square meters of floor space and 1,500 rooms, the Winter Palace was among the world’s grandest building. On Dec. 17, 1837, a fire broke out at the Winter Palace. By the morning of Dec.19, only the structure’s framework remained.

For the czar (沙皇) , the fire presented a political challenge. Fearing that Russia's enemies would cast the fire as a blow to the czarist orders, the czar’s supporters quickly worked together to shape the description of the fire in Russia and abroad. They wanted the country to appear united. And they certainly didn't want despair to become the story.

The first full account of the fire was written in French by the poet Petr Viazemskii. A Russian translation appeared two months later. That text and others painted a highly idealized picture of the response to the tragedy. The accounts noted that the czar forcefully directed the fire’s containment. Soldiers were selfless to save the palace. The Russian people felt the loss just as deeply as the czar.

To erase the shame of the fire, the czar set a nearly impossible goal: rebuild the palace within 15 months, and he ordered that rebuilt palace look exactly as it had before.Thousands of workers labored on the construction site. They made rapid progress. On Match 25, 1839, the czar celebrated the rebirth of the Winter Palace.

Outwardly identical to the old version, the new palace featured more iron and brick in its structures---and less wood. It was far less fire-prone than the original.

Notre Dame hasn’t experienced the same level of destruction as the Winter Palace, if the Russian phoenix of 1839 is any indication, there is hope that a renewed Notre Dame will once again grace the banks of the Seine.

1.What do we know about the fire in the Winter Palace?

A. It burnt down 60,000 rooms

B. It lasted more than 24 hours

C. It was set by Russia’s enemies

D. It completely destroyed the palace

2.Why did the czar decide to rebuild the palace in a short time?

A. To secure his power

B. To challenge his enemies

C. To unite French people

D. To celebrate his birthday

3.What did Viazemskii and others stress in their accounts?

A. The scene of the fire

B. The selflessness of the czar

C. The Russians’ joint effort to fight the fire

D. The ideal result achieved by the Russians.

4.What’s the author’s purpose in writing the passage?

A. To describe a fire at the Winter Palace

B. To praise the renewal of the Winter Palace

C. We express sympathy for the Notre Dame

D. To inspire confidence in rebuilding the Notre Dame.



??? Many of the most striking beasts on the planet come in only two colors: black and white. These high-contrast markings represent some of the nature's most diverse evolutionary choices. For some animals, black -and- white coloring is a way to warn off natural enemies. For others, to keep insects away. For still others, it creates a clever cover. Spend some time exploring what science has discovered about these animals’ appearances, and you will see that basic black and white isn't so basic after all.


Depending on the species, black skunks may wear white spots that act as a cover or white stripes(条纹)that signal enemies to watch out for their smelly spray.

Giant Panda

Resent insights into panda coloring have come from studying each body part separately. Black ears indicate fierceness, and distinct eye patches aid in individual recognition. The panda in white body hides it against snow, white its dark limbs(四肢) keep it from being spotted in forests, a compromise developed from its poor bamboo diet:Bamboo doesn’t let pandas build up enough fat to hibernate(冬眠), forcing them to spend winters in the snow.


Even when a badger is in its cave, its facial stripes can be seen, Zoologists say the warning coloration helps the small animal prevent natural enemies.


In bright sun, the buck’s white stomach reduces the effect of the shadow cast by his back, allowing him to appear one color and two dimensional---especially hiding from natural enemies in his own shadown.

A. Skunk and Badger B. Giant panda and Zebra
