A. Choose the best answer:
Researchers said they had found out that there was once an ancient fresh water lake on Mars that might have been able to support life.
A team of researchers from the US Curiosity Rover Mission, analyzed (分析) some mudstone and fine-grained sediment (细粒沉积物) which can tell us that there was at least one lake around 3.6 billion years ago.
The team said their analysis showed that the lake was calm and likely had fresh water, including key biological elements, such as carbon, hydrogen, oxygen, nitrogen and sulphur (硫磺). Theoretically, such a lake would provide perfect conditions for simple living things.
The findings were published in the US Journal Science and presented at the American Geophysical Union’s fall meeting in San Francisco. “It is important to note that we have not found signs of ancient life on Mars. What we have found is that there once existed a lake on its surface which might make it possible for some simple living things to live billions of years ago,” Professor Sanjeev Gupta said in a statement. Gupta described the new research as “a huge positive step” for the exploration of Mars.
In previous studies, scientists found evidence of water on Mars’ surface in other rocks. However, the new research provides the strongest evidence yet that Mars could have been habitable enough for life to continue.
( ) 1. Researchers have found evidence that an ancient fresh water lake probably existed on ______.
A. the Earth B. Venus C. Mars D. the Moon
( ) 2. The following biological elements EXCEPT ______ have been found on Mars according to the analysis.
A. oxygen B. nitrogen C. hydrogen D. carbon dioxide
( ) 3. The underlined word “habitable” in the last paragraph probably means “______” in Chinese.
A. 可居住的 B. 无法生存的 C. 习惯的 D. 不可能的
( ) 4. Which of the following is TRUE according to the passage
A. The researchers thought it impossible for a fresh water lake to exist on Mars.
B. Gupta thought of the new research as “a huge positive step” for the exploration of Mars.
C. Researchers have taken great efforts to find signs of ancient life on Mars.
D. The findings about the fresh water lake haven’t been published in the US Journal Science.
( ) 5. On which column of a book can you find this passage
A. Science. B. Travelling. C. Life. D. Education.

A. How did the fresh water lake disappear on Mars B. Ancient life signs found on Mars.

“Please,” Mr Smith said, “I am dying of thirst. Let me have some of your water.”
The man slowly shook his head. “You can’t have any water,” he said, “but I’ll sell you a necktie (领带).”
“I don’t want a necktie.” Mr Smith shouted at him furiously (狂怒地). “I need water.”
