The snow cap of Mount Kilimanjaro, famous in literature and beloved by tourists, initially formed some 11,000 years ago, but will be gone in two decades, according to researchers who say the ice fields on Africa’s highest mountain shrank by 80 percent in the past century.
Lonnie G. Thompson,one professor from Ohio State University, said measurements using modern navigation satellites show that the oldest ice layers on the famous mountain were deposited during an extremely wet period starting about 11,700 years ago.The mountain appears in literature, most notably Ernest Hemingway’s “The Snows of Kilimanjaro” and some ancient beliefs in Africa hold the mountain to be a sacred place.
But a temperature rise in recent years is destroying the 150-foot-high blocks of ice that gave Kilimanjaro its unique white cap.“The ice will be gone by about 2030,” said Thompson. The disappearing ice already has reduced the amount of water in some Tanzanian rivers and the government fears that when Kilimanjaro is bald of snow the tourists will stop coming.
“Kilimanjaro is the number one foreign currency earner for the government of Tanzania,” said Thompson. “It has its own international airport and some 20,000 tourists every year. The question is how many will come if there are no ice fields on the mountain.”
Africa was not alone in the global drought. Thompson said other records show that civilizations during this period collapsed in India, the Middle East and South America.
Researchers put markers on the ice field blocks in 1962 and Thompson said measurements using satellites show the summit of the ice has been lowered by about 56 feet in 40 years. The margin of the ice also has moved back more than six feet in the past two years, much smaller than before.
“That’s more than two meter’s worth of ice lost from a wall 164 feet (50 meters) high,” said Thompson. “That’s an enormous amount of ice.”The snow cap of Mount Kilimanjaro ________.

When I was young, I had an old neighbor named Dr. Gibbs. He didn’t look like any doctor I’d ever known. He never shouted at us for playing in his yard. I remembered him as a neighbor who was nicer than anyone else in the neighborhood.
When Dr. Gibbs was happy, he was planting trees. And his life’s goal was to make it a forest.
Dr. Gibbs had some interesting theories about planting. He talked about trees that weren’t watered would grow deep roots in search of water. So he never watered his trees. He planted an oak (橡树) and, instead of watering it every morning, he beat it with the rolled-up newspaper. I asked him why he did that, and he said it was to get the tree’s attention.
Dr. Gibbs died a couple of years. Every now and again, I walk by his house and look at the trees that he planted twenty-five years ago. They’re very strong now.
I planted a couple of trees a few years later. I watered them regularly and took good care of them. Whenever a cold wind blows, they shake their leaves and branches.
The funny thing about those trees of Dr. Gibbs was that difficulty seemed to help them in ways comfort and ease never could.What was Dr. Gibbs’ life goal?
A.To build a forest. | B.To save more lives. |
C.To make a lot of money. | D.To study plants. |
One of Dr. Gibbs’ theories about planting was that ______.
A.he often talked to the trees | B.he kicked the trees heavily |

Streit was an experienced safecracker who never used force —either against people or safes (
保险箱). He was a real artist of his trade and it took him only 19 minutes to open the most difficult safe he had ever encountered. In about 10 years, helped by his brother Stefan and two friends, he took about $330,000 —from the safes of 28 banks in Austria. On his last job, early in 1999, he left the safe door open and $80,000 behind. With the money ws a note, "We don’t need all that much."
A witness (
目击者) recognized his car and Streit was caught by the police. Then he was sent to Austria’s Stein Prison to serve a six-year sentence. He boasted (吹嘘) at his trial that he would continue breaking the law, "I am a thief and I shall use every opportunity." Despite the warn-ing, prison officials moved Streit to the prison’s blacksmith (铁匠) shop. One day during the week before Christmas, Streit disappeared. Searchers found all his doors were well locked. Streit had managed to make a set of keys and let himself out.
Not to freedom, though. After crossing into Bavaria, Streit attracted the suspicion (
怀疑) of German customs police on purpose and got himself arrested. "I want to be in a German prison,"he explained to the surprised police. "As German courts give much milder (温和的) sentences for crimes like mine and will reduce the time I would otherwise have served in Stein Prison."
In prison, Streit persuaded his keepers to let him make a Christmas Eve telephone call to his former keeper, Karl Schreiner of Stein Prison. "I’m sorry if I caused trouble. I didn’t want to embarrass anybody by escaping. Conditions weren’t that bad. In fact the food was better than it is here."

Four decades ago a group of college students visited the mountains of Borneo to examine moth (蛾) populations. Now a team of British scientists, including a member of the original trip, has returned to the same sites to repeat the survey. They have found that, due to rising temperatures, the insects now live 68 meters higher.
Global warming is forcing tropical (热带的) species uphill to escape the rising temperatures at a rate of nearly 2 meters a year, the new study from Borneo suggests.
Since this was the only chance to repeat the original survey, the scientist did everything they could to do it exactly the same way, going at the same time of year, in July and August, using photographs to find the exact original sites of the moth traps.
"While this is the first study of insects, a few other studies of tropical species are starting to appear," said Thomas. "If you look across all those studies, you’ll find the same results, and it’s extremely difficult to think of any other explanation for them."
While some species might survive by finding places on the mountains with temperatures similar to those of their original habitats, others may run out of habitat on the rocky peaks, warns the study.
In a paper in the journal Naturein 2004, Thomas and 13 other experts analyzed the habitats of 1,100 species on five continents, and estimated that on average one quarter were at risk of extinction.
Last year a paper published in the Public Library of Science in the US warned that the risk of extinction in the tropics was becoming more and more serious. The authors, Jana and Steven Vamosi, estimated that 20-45% of tropical species were at risk of extinction.
If the temperature continues to rise at the same rate for ten years, the insects will live about ______.
A.6.8 meters higher | B.19 meters higher |
C.34 meters higher | D.68 meters higher |
What’s the problem for some species moving up mountains?
A.There’ll be too little space. |
B.The temperature will be much too low. |
C.They will be at greater risk of extinction. |
D.They’ll find it hard to adapt to the environment. |
We can learn from the passage that ______.
A.this survey of moths has been carried out many times |
B.some scientists have put forward other explanations for the results |
C.scientists tried to repeat the original survey |
D.20-45% of tropical species were estimated to be at risk of extinction in 2004 |

A.Climate change forcing moths higher. |
B.Protecting moths from extinction. |
C.How to research tropical moths. |
D.How to study moths living on mountains. |
