US researchers have found traces of an anc
ient lake on Mars recently, increasing hopes of discovering evidence that billions of years ago the Red planet hosted life.
The lake, which dates back some 3.4 billion years, appears to have covered as much as 80 square miles and was up to 1,500 feet deep, said the team from the U
niversity of Colorado.
“This is the first clear evidence of shorelines on the surface of Mars,”said Boulder’ s research associate, Gaetano Di Achille, in a study published in the latest edition of Geophysical Research Letters.
“The identification of the shorelines and accompanying geological evidence allows us to calculate the size and volume of the lake, which appears to have formed about 3.4 billion years ago.”
Analysi
s of the images has shown the water carved out the canyon (溪谷) in which it was found, which then opened out into a valley depositing (使淤積) sediment (沉積) which formed a delta (三角洲).
“Finding shorelines is a great discovery to us,” said assistant professor Brian Hynek, adding it showed the lake existed at a time when Mars was thought to have been cold and dry.
Scientists believe the oldest surfaces on Mars formed during the wet and warm era known as the Noachan epoch, about 4.1 billion to 3.7 billion years ago.
The newly discovered lake is believed to date from the Hesperian era and postdates the end of the warm and wet period on Mars by 300 million years, according to the study.
Scientists believe deltas next to the lake may well hold secrets about past life on Mars as such places on Earth have become the natural deposits of organic carbon and other markers of life.
【小題1】The size of the lake found on Mars is ______.
| A．80 square miles | B．1,500 square miles |
C．3.4 billion square miles | D．300 million square miles |
| A．hot and wet | B．wet and warm | C．cold and dry | D．cold and wet |
A．Because similar places on Earth have become natural deposits of marker s of life. |
| B．Because someone has put secrets about past life on Mars there. |
| C．Because past life has been found in other deltas on Mars. |
| D．Because some people are said to have already seen life marks there. |
| A．The Noachan epoch was a wet and warm era. |
| B．The lake might have existed 3.4 billion years. |
| C．The discovery can’ t fully prove that the Mars once hosted life. |
| D．The lake traces prove that there exists life on Mars now. |

The United States will introduce a new and comprehensive(綜合的) exam for students who seek to study in American and other English-speaking countries, Xinhua News Agency reported from New York.
The exam, which stands for a great change from the current English level test, was disclosed by Theresa Chang Wei Jen, associate director of the International Service of the US College Board, America’s leading educational organization.
The Advanced Placement International English Language (APIEL) will be offered for the first time throughout the world on May 10, 2002, said Jen.
However, the APIEL is a strange title to most Chinese students, and it is unlikely to soon gain the similarity of other already existing exams, such as the TOEFL(Test of English as a Foreign Language), the GRE(Graduate Record Examination), or the IELTS(International English Language Testing System).
“I have never heard of such a test and I would prefer the IELTS if I need another exam,” said Xu Jingyan, a graduating student from Beijing University of Aeronautics and Astronautics, who wants to study in England and has already taken the TOEFL.
Most of Xu’s classmates have never heard of the APIEL. “The APIEL is designed for international students who wish to get university studies in English-speaking countries, including the United States, Britain, Canada, and Australia.” said Jen.
The APIEL has been adopted, said Jen, because the TOEFL can no longer accurately reflect the abilities of students of using the English language comprehensively in an academic environment. Xinhua reported that a fairly large number of foreign students who earned high scores in TOEFL exam turned out to be very ordinary educational performers after admission.
Compared with the TOEFL, the APIEL measures a student’s ability to read, write, speak and understand English through testing his or her skills in listening comprehension, speaking with accuracy(精確) and resourcefulness, and writing with clarity and fluency(流暢), Jen said.

CARDIFF, Wales Poets, singers and musicians from across the globe gathered in Wales to celebrate the tradition(傳統) of storytelling.
“It might seem strange that people still want to listen in age of watching television, but this is an unusual art form whose time has come again,” said David Ambrose, director of Beyond the Border, an international storytelling festival(節) in Wales.
“Some of the tales, like those the Inuit from Canada, are thousands years old. So our storytellers have come from distant lands to connect us with the distance of time,” he said early this month.
Two Inuit women, both in their mid 60s, are among the few remaining who can do Kntadjait, or throat singing, which has few words and much sound. Their art is governed by the cold of their surroundings, forcing them to say little but listen attentively.
Ambrose started the festival in 1993, after several years of working with those reviving (coming back into use or existence) storytelling in Wales.
“It came out of a group of people who wanted to reconnect with traditions. and as all the Welsh are storytellers, it was in good hands here.” Ambrose said.
