Chuck，unlike other frogs，didn't like catching flies himself. But he did love eating them.

Some frogs thought Chuck was lazy. Some believed he must think he was too good for them. Some thought Chuck was the strangest frog ever.

That didn't matter to Chuck. Each morning，Chuck jumped over and sat under the spider's web. Then when Lady Eightlegs went off to dip (浸) her feet in the pond，Chuck ate flies from her web.

One morning while Chuck was enjoying his fly breakfast，Lady Eightlegs returned and caught him.

“You're the one who keeps eating my flies！”she cried.

Chuck jumped away and into the pond. Now there was an idea！Why not spin (结) his own web?

He collected some vines (葡萄藤) from a nearby farm. Then he began to spin his web. He worked on his web for hours，until very late at night. And then he fell asleep.

When he woke up the next morning，he found that he got caught by the vines.

“Help！”he shouted.

Lady Eightlegs looked up from the edge of the pond. She hurried up to help Chuck out of the vine web.

“No matter how hard I try，I can't spin a spider's web，”Chuck said.

“Of course not，”Lady Eightlegs said. “You're a frog. Frogs can't spin spider's webs any better than spiders can swim，I guess.”

“But I always see you in the water，”Chuck said.

“I only wade in (蹚水) up to my knees，”Lady Eightlegs sighed. “How wonderful it would be to swim in the middle of the pond and float (漂浮) peacefully under the sun.”

Chuck smiled，“I have an idea.”

From that day forward，Chuck carried Lady Eightlegs out to the middle of the pond，where they floated and played together. When they returned to land，they shared a breakfast of flies from her spider's web.

It wasn't exactly an ordinary friendship. But Chuck was not an ordinary frog.

A new study shows one of the largest glaciers① in Greenland is becoming smaller and speeding to the sea faster than scientists expected. If it continues, Greenland itself could become much smaller during this century and global seas could rise as much as 3 feet.

The rates② of change that we’re noticing are much higher than expected. If these rates continue, it is not unlikely that Greenland could shrink③ by several tens of percent this century. However, it’s not known how quickly this coastal response of the Greenland ice sheet melting will have an effect on the vast inland ice.

Greenland is the world’s largest island, covering an area more than three times the size of Texas. Some 81 percent of it is covered by ice, and there are many glaciers. Glaciers are like slow-moving rivers of ice. Where a glacier meets the sea, its weight keeps it firmly resting on the bottom. A glacier’s front is the point where the water is deep enough that the glacier floats.

Since the 1970s, the front of Helheim stayed in the same place. Then it began melting rapidly, moving back 4.5 miles from 2001 through this past summer. It has also grown thinner, from top to bottom, by more than 130 feet since 2001. And over these past four years, its trip to the sea has sped up from about 70 feet per day to nearly 110.

The melting is driven by a warmer climate. Temperatures in Greenland have risen more than five degrees Fahrenheit in the last decade. Since most of Greenland’s ice is on land, seas will rise as the ice melts. If all Greenland’s ice sheet melted, oceans would be 15-20 feet higher. Nobody expects that to happen anytime soon.

Notes:

① glacier  n.  冰川

② rate  n.  比率

③ shrink  v.  缩小

1. Which of the following about the glaciers is TRUE?

  A. Glaciers only lie in Greenland.        B. Water in glaciers is more than sea water.

  C. Glaciers sometimes float on the water.  D. Glaciers can increase the water level of lakes.

2. According to the text, we know that Greenland ______.

  A. belongs to Canada                  B. is the largest island in North America

  C. is all covered with glaciers            D. is sinking under the sea level

3. Which of the following may be the result of the disappearing of Greenland glaciers?

  A. the climate of the world will be warmer.

  B. the glaciers in other area will be bigger.

  C. It will be easy for explorers to visit the island.

  D. Some coastal cities may be under the sea.

完形填空

　　One way of preventing (阻止) floods may be by making rain! This may sound rather 1 . As we know, heavy rain is the 2 of floods, and in Malaysia, most of the 3 are caused by the annual monsoon (一年一度的湿季风), which brings heavy rain to the east coast. If, 4 , the rain could be made 5 in the South China Sea, there would be 6 floods since the rain could not reach the east coast.

　　Is it possible to make 7 give up their rain? Yes, it is.

　　As you probably know, clouds are caused 8 air containing water-vapor (水蒸气). The air rises and, since water-vapor 9 water when it cools, very tiny drops of water are formed. Since these drops are very 10 , they float (漂浮) in the air and 11 a cloud. When the cloud rises, however, the drops become 12 . Because of this, they 13 together and become big drops. The big drops are no longer able to float because of their 14 , and they fall. As they 15 , they pick up more drops and become bigger. This is the cause of rain.

　　Rain making 16 making these bigger drops form and fall 17 they would normally do so. This can be done by “seeding” the clouds with chemicals, 18 planting seeds in the ground. Rain can be produced 19 by these chemicals. The seeding is done by 20 which fly through the clouds.

　　Man always wanted to fly. For hundreds of years they watched birds flying and wished that they could fly, too. Birds fly very easily. They spread(展开) their wings(翅膀) and float (漂浮) on the air. The air keeps them up for many hours.“If birds and kites can stay up in the air, perhaps we can, too.”they thought.

　　At first they made wings like birds. Then they jumped off high buildings in order to fly. Many men did this but they all failed. After many failures (失败) they stopped trying to fly with wings. Then two brothers tried another way. They tried balloons (气球).“Hot air is lighter than cold air,”they said, “That is why hot air goes upwards. If we fill a balloon with hot air, it will go upwards.”

　　After many experiments, they made two men go up in a balloon full of hot air. A great crowd of people watched. The balloon rose to a height (高度) of 900 metres. The wind blew it along for nine kilometers. Then it came gently back to earth. For the first time man traveled through the air!
