The surface of Venus(金星)has never seemed very hospitable. Temperatures change around 470°C(900°F), the result of a runway greenhouse effect,and the pressure of its atmosphere, thick with carbon dioxide and sulfuric acid, is some 90 times that of Earth’s. Lead(铅)would flow like water on Venus, and water cannot have existed in liquid form for perhaps a billion years.
Now NASA’S Magellan spacecraft seems to have found one more horror in the nasty landscape: active volcanoes. Last week the space agency released the first detailed map of Venus and the most dramatic images ever made of its surface. The picture offer the best evidence to date that a planet once assumed dead is actually a lively pot of geological change.
The most amazing image is of Venus’s second tallest mountain, Maat Mons, which rises 8km(5 miles) . Most of the planet’s many peaks, including 9.5-km-(6-mile-) high Maxwell Montes, look bright in the radar pictures Magellan takes from its orbit above the permanent could cover. That means they are strong reflectors of radar waves. But Maat Mons is dark; like the Stealth bomber, it absorbs much of the radar falling on it.
This interesting fact, say project scientists, is a strong hint that the mountains has recently been covered with lava(^§S). Rock that sits on the surface of mountaintops appears to weather quickly in the hot,chemically reactive atmosphere, creating a soil that is rich in iron sulfide(硫 化铁)• It is this mineral, the scientists believe, that can easily be seen on radar. If Maat Mons doesn’t have any, it has probably been resurfaced, perhaps within the past few years.
Such resurfacing has undoubtedly taken place in Venus lowlands: earlier images of the planet showed vast areas that are remarkably free of craters(火山坑).That would be easy to explain on a Planet like Earth, where cratering from meteor strikes is erased by steady erosion. But while there is some evidence of wind erosion on Venus, the best explanation for the lack of cratering is periodic lava flow. Magellan has found direct evidence of such flows, including domelike upwellings and hardened streamed of rock trailing down the sides of Venusian peaks. There are also signs of other geologic activities, including dramatic faulting and several distinct incidents of mountain building. But the evidence can’t indicate whether they really occurred millions of years ago. The case for active Venusian volcanoes is not yet proved, but Magellan, which is now well into its second complete survey of the planet’s surface, may eventually settle the issue.
1.Which of the following can not be possibly found on Venus now?
A. Carbon dioxide B. Sulfuric acid
C. Liquid water D. Active volcanoes
2.The scientists believe that shows up easily on radar.
A. geological change B. iron sulfide
C. mountain mineral D. lava flow
3.Which of the following is TRUE according to the passage?
A. The resurfacing has changed the images of the vast areas in Venus lowlands.
B. The wind erosion on Venus is caused by periodic lava flows
C. Streams of rock trailing down the side of Venusian peaks can be seen on Earth
D. Other geologic activities have caused dramatic and unbelievable climate phenomena.
4.What can be inferred from the passage?
A. NASA’S Magallan spacecraft fails to stand the environment of Venus.
B. There is clear and confirmed evidence for the active Venusian volcanoes on Venus.
C. Some evidence of periodic lava flows has been found by NASA astronauts.

There was great excitement on the planet of Venus(金星) this week. For the first time Venusian scientists managed to land a satellite on the planet Earth, and it has been sending back signals as well as photographs ever since.
The satellite was directed into an area known as Manhattan (named after the great Venusian astronomer Prof. Manhattan, who first discovered it with his telescope 20000 light years ago).
Because of excellent weather conditions and extremely strong signals, Venusian scientists were able to get valuable information as to feasibility (可行性) of a manned flying saucer (碟) landing on Earth. A press conference was held at the Venus Institute of Technology.
“We have come to the conclusion, based on last week’s satellite landing,” Prof. Zog said, “that there is no life on Earth.”
“How do you know this?” the science reporter of the Venus Evening Star asked.
“For one thing, Earth’s surface in the area of Manhattan is made up of solid concrete and nothing can grow there. For another, the atmosphere is filled with carbon monoxide (一氧化碳) and other deadly gases and nobody could possibly breathe this air and survive.” “What does this mean as far as our flying saucer program is concerned?”
“We shall have to take our own oxygen with us, which means a much heavier flying saucer than originally planned.”
“Are there any other dangers that you discovered in your studies?”
“Take a look at this photo. You see this dark black cloud hovering(盘旋) over the surface of Earth? We don’t know what it is made of, but it could give us a lot of trouble and we shall have further tests before we send a Venus Being there.”
“Over here you will notice what seems to be a river, but the satellite findings indicates it is polluted and the water is unfit to drink. This means we shall have to carry our own water, which will add even greater weight to the saucer.”
“If all you say is true, won’t this set back the flying saucer program several years?”
“Yes, but we shall continue as soon as the Grubstart gives us the added funds.” Prof. Zog replied.
1.During the week of great excitement the Venusian scientists succeeded in getting important information as to ____.
A. the feasibility of landing a satellite on Earth
B. the possibility of making a first-rate flying saucer
C. the feasibility of sending a Venus Being to Earth
D. the possibility of directing a flying saucer into Manhattan
2.According to Prof. Zog, the Venusians will have to take their own oxygen with them when they carry out their flying saucer program because ____.
A. they need it in their way to the planet of Earth
B. the Earth’s atmosphere is filled with deadly gases
C. there is a low level of oxygen for Venusians
D. there is no air on the planet of Earth
3.The “dark black cloud” on the photo refers to ____.
A. the polluted air hovering over the surface of Earth
B. the mass of tiny drops of water floating above Earth
C. the mass of small things moving through the air
D. the dark clouds gathering before a storm breaks
4.The author wishes to call our attention to the fact that ____.
A. that modern man has polluted his environment to such an extend that he might destroy himself if he went on like this
B. that there is a point in spending billions to land a flying saucer on Earth
C. that pollution has become so serous a problem on Earth that even Venusians find life there unbearable.
D. that it is difficult if not altogether impossible, to land a manned flying saucer on Earth
