The great Alaskan explorer John Muir once wrote that to have dinner with a glacier on a su

nny day is an excellent thing. It is better to sleep beside one, on an Antarctic island, with just a sleeping bag for warmth and the sky as your tent. Our camp-out was in early January of this year on Danco Island, along the Antarctic Peninsula. Midway through a 10-day Antarctic journey, conditions were near perfect. We started our voyage from the Akademik Loffe in Zodiacs, landing on the wide beach with its fist-sized rocks. At the height of the Antarctic summer, the shore was clear of snow, with plenty of rooms for the 40 adventurers to spend the night. Daneo Island was charted in 1898 by the Belgian explorer Adrien De Gerla-che, who was the first to prove that you could overwinter in Antarctica and survive. De Gerlache paved the way for Lt. Robert Scotts first expedition in 1901. De Gerlache mapped the archipelago(群岛).He later named the island after his team member Emile Danco, a geophysicist who died that winter. For one year in the mid-1950s, Danco was known as a base by the British, who kept a scientific research station there, although all that remains of it is a foundation and a pile of coal. Our expedition was organized by Australian tour operator Peregrine Adventures. The weather was extraordinary-sunny with daytime temperatures of about 1~2°C. The camping was easy and accessible to all ages. Sleeping under the stars in Antarctica, in just a sleeping bag is pretty amazing.

Whom did Adrien de Gerlache have a direct effect on？

A．John Muir.

B．Lt. Robert Scott.

C．The tourists.

D．The author.

It seems to shine unchangingly, pouring out a constant light year after year. But the sun

may not be nearly so stable as we suppose. It is now thought to move quickly and irregularly and change in long-term cycles, growing dimmer and then brighter with each passing year. Some even fear that its frequent changing behavior. would have a great influence on the Earth' s climate.

The source of the sun' s inconstancy is magnetism. Professor William Livingston has developed new theories about its magnetic nature.

"We don' t yet know what causes sun spots, "he says, "but we now think they ' re areas of high level magnetism that come up from the sun' s interior. So strong is their magnetic pull that the highly ionized gas nearby is not able to transmit energy out. "As a result these areas send out less heat and light and thus appear from Earth to be almost dark irregular surface patches.

Sun spot activity generally fluctuates in steady, 11-year cycled. Scientists have long formed the o pinion that as the size and number of sun spots increased, the overall energy sent out by the sun would de crease. Indeed, recent studies confirmed it, revealing that during peak periods of sun spot activity, the Earth experiences a small drop that can be seen clearly in received solar energy.

Could such a small drop in energy have an effect here on earth？ Perhaps some scientists think the world temperature could fall by' as much as 0.2 during periods of high solar magnetism.., enough to cause significant fluctuations in weather patterns.

According to the passage, it is believed that the sun ______ ．

A．moves in a quick but steady way year after year

B．sends out less and less heat and light with each passing year

C．radiates the same amount of light every year

D．might have a strong influence on the weather patterns

Juan Ponce de Leon was the first Spaniard to touch the shores of the present United States

. Just as Columbus had not remotely realized the extent of his momentous discovery, de Leon never dreamed that his "island" of Florida was a peninsular extension of the vast North American continent. After coming to the New World with Columbus in 1493, he had led the occupation of Puerto Rico in 1508 and governed it from 1509 to 1512. In 1509, de Leon started a colony at Caparra, later abandoned in favor of San Juan. He was one of the first adelantados -- men who "advanced" the Spanish Empire by conquest, subjugation of the Indians and establishment of a semi-military government.

In Puerto Rico he heard a legend about an island called Bikini, where there was said to be a spring that restored youth to all who bathed in it. It is said he was seeking this spring when he discovered Florida.

He sailed from Puerto Rico in March 15i3. On Easter Sunday he sight ed the coast. A few days later he landed on Florida's east coast, near what is now St. Augustine. He named the place La Florida after the Spanish term for Easter Sunday -- Pascua Florida, or "flowery feast." He then sailed around the peninsular and up the west coast. He returned to Florida in 1521.

In what year did de Leon discover Florida ？

A．1508.

B．1513.

C．1521.

D．1492,

听力原文：Texas' attorney general on Thursday pledged his full cooperation with Mexican law

enforcement to combat drug violence that has killed hundreds of people south of the U.S. border this year.

Attorney General Greg Abbott met with top Mexican officials in Mexico City to explore ways to Stop the violence between feuding drug gangs that has killed more than 170 people in towns south of Texas this year.

"Dozens of people are dead because this drug war has spiraled out of control," Abbott told reporters. "If we fight crime only on one side of the border, the criminals simply shift to the other side."

Abbott spoke to reporters after meeting with Mexico's attorney general, Daniel Cabeza de Vaca, and officials including the governor and attorney general of northern Tamaulipas state.

Violence in northern Mexico has soared this year as cartels from the western state of Sinaloa battle local Gulf cartel rivals for control of the lucrative cross-border cocaine, marijuana and amphetamine trade.

Earlier this year, the U.S. government called on Mexico to combat violence on the border, and twice warned U.S. citizens about travel to cities south of the Rio Grande. Mexico told Washington to stay out of its affairs.

Abbott expressed particular concern for security in Nuevo Laredo, south of Laredo, Texas, where 87 people have been murdered this year and some 30 U.S. citizens have been kidnapped since last August.

"We want to do everything we can to eliminate violence ... and keep residents of Laredo and Nuevo Laredo as safe as possible," he said.

Abbott said Texas has allocated $5 million to improve law enforcement communication in border communities since the crisis in Nuevo Laredo began last year, including $1.2 million for the Laredo area.

Governors from states on both sides of the 2,000-mile border are meeting in the Mexican town of Torreon on Thursday and Friday. Crime and border security are high on the agenda.

How many people have been killed in drug violence in towns south of Texas this year？

A．150.

B．160.

C．170.

D．180.
