     US researchers have found traces of an ancient 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 University 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."

   Analysis 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 (使淤积) sediment (沉积) 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.

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.

4. Which of the following statements is NOT true according to the passage?

A. The Noachan epoch was a wet and warm era.

B. The lake might have existed 3.4 billion years.

2000年5月12日，甲、乙两厂签订购销合同。双方约定：乙厂供应甲厂洗衣机零配件5万套，每套价格10元；乙厂于同年6月10日，每月交货1万套；甲厂于签约后10天内付乙厂定金5万元；乙厂每月月底交货，甲厂收货后10天内验货付款；违约责任为未履行货物价款的5%。甲厂依约付给乙厂定金。在乙厂履行了第一、二批交货义务后，适逢一外商紧急求购这种洗衣机零配件，出价远远高于甲厂在合同中约定的价格。于是乙厂就另和外商签订了以这种洗衣机零配件为标的的购销合同。由于生产能力有限，乙厂遂不再履行其与甲厂签订的购销合同，要求解除第三、四、五批的合同。甲厂不同意解除合同，并要求乙厂支付违约金并双倍返还定金。乙厂认为，甲付给其的5万元定金根本没有投入使用，况且合同才签订3个月，也没有给甲厂造成实际经济损失，双倍返还定金并支付违约金是显失公平。因此，乙厂只同意返还甲厂的5万元定金。于是甲、乙两厂发生纷争，甲厂起诉到法院。
