volcanoes (中译英)大家有空帮我看看哪写错了呀 谢谢

Getting close to active or erupting volcanoes can be dangerous. But for Michael Rampino, it’s all in a day’s work. Rampino is a volcanologist, a scientist who studies volcanoes and how they affect our planet. Rampino has been close to red-hot lava flows (熔岩流) in Hawaii and explosive volcanoes in Indonesia. He knows when to get close to an active volcano and when to back away.
Rampino wasn’t always a volcanologist. He worked for NASA for seven years. He studied rocks until he began to research climate change and the effects that volcanoes have on climate. He became interested in the subject. “Once I started working with volcanoes,” Rampino said, “I was hooked .”
Rampino is a professor at New York University. As part of his job, he travels to areas where volcanoes have been active. “Active” means they have erupted within the past few centuries and probably will erupt again. Rampino studies the deposits (沉积物) of ash and other materials from the eruptions. The ash may hold clues to what happened to the Earth in the distant past. It may also help scientists predict what could happen to Earth’s climate in the future.
Rampino doesn’t work alone. He works with a team of scientists who use computers to stimulate (模拟) the effects volcanoes have on Earth’s atmosphere.
Being a volcanologist may be hard work, but it’s also fun. “It’s cool traveling the world studying volcanoes,” Rampino says. When he talks to students about his work, he tells them that his goal is “to understand the events that have shaped Earth’s history.”

D．Business.

Scientists know of more than 1,000 volcanoes on the surface of Venus, Earth’s “sister” planet. A big question has been: Are they still active? The scientists say yes.
Their evidence for recent volcanic activity on Venus comes from a lava(熔岩) flow in the planet’s northern hemisphere. The flow is hotter than the rocks around, which means the lava might still be cooling off. “The flow we studied seems to be very young---it is still warm inside,” Nataliya Bondarenko said.
Venus is a difficult planet to study from Earth because it is surrounded by thick clouds. Telescopes on Earth can’t see through these clouds, so the best information about Venus comes from spacecraft orbiting it.
Bondarenko and her colleagues studied the lava flow using data from NASA’s Magellan mission. That spacecraft spent four years in orbit around Venus and used radar to make a map of 98 percent of the planet’s surface. On October 11th, 1994, the mission ended, and the spacecraft plunged (跌落) through Venus’ heavy cloud cover and crashed onto the planet below.
While in orbit, the Magellan craft sent microwaves, which can go through Venus’ clouds, to the surface. Microwaves are invisible and can be as long as three feet. These waves are a kind of energy, like light. And like light, they bounce off surfaces. The way the waves bounced off the Venus’ surface and back to the craft supplied information that the scientists used to estimate the temperature of various parts of the planet’s surface. Bondarenko’s team found that the lava flow was hotter than its surroundings---which may mean the lava flow is in the process of cooling.
The scientists say the lava flow can’t be very old because if it were, it would have cooled off enough that Magellan wouldn’t have noticed the difference in microwaves. She adds that the flow appears in a 1978 view of the surface that a craft called the Pioneer Venus Orbiter captured.
小题1:What happened to Magellan in the end?

A．It was floating in space forever.

B．It flew into heavy clouds.

C．It returned to the Earth.

D．It fell onto Venus.

小题2:How could Bondarenko judge the temperature of the Venus?

A．By looking at it with a powerful telescope.

B．By measuring the thickness of clouds over Venus.

C．By calculating the microwave bouncing off Venus’s surface.

D．By orbiting Venus for 4 years in a spacecraft.

小题3:The best title for the passage may be “______ ”.

A．Warm lava on Venus

B．More volcanic eruptions on Venus

C．Venus is just like a big active volcano

D．Lava flows are first found on Venus

Geologists have been studying volcanoes for a long time.Though they have learned a great deal,they still have not discovered the cause of volcanic action.They know that the inside of the earth is very hot,but they are not sure exactly what causes the great heat.Some geologists have thought that the heat is caused by the great pressure of the earth’s outer layers.Or the heat may be left from the time when the earth was formed.During the last sixty years scientists have learned about radium,uranium,thorium,and other radioactive elements.Many scientists now believe that much of the heat inside the earth is produced by radioactive elements.
Whatever the cause of the heat may be,we do know that the earth gets hotter the farther down we dig.In deep mines and oil wells the temperatures rise about 1°F for every 50 feet.At this rate of the temperature 40 miles below the earth’s surface should be over 4 000°.This is much hotter than necessary to melt rock.However,the pressure of the rock above keeps most materials from melting at their usual melting points.Geologists believe that the rock deep in the earth may be plastic,or puttylike（油灰状的）.In other words,the rock yields slowly to pressure but is not liquid.But if some change in the earth’s crust releases the pressure,the rock melts.Then the hot,liquid rock can move up toward the surface.
小题1:The cause for the great heat inside of the earth is______.

A．great pressure of the earth’s outer layers

B．the heat left from the time when the earth was formed

C．radioactive elements giving out heat

D．not sure

小题2:According to the passage,______ prevents most rock from melting at its usual melting points.

A．the pressure of the rock itself

B．the pressure of the rock above

C．the pressure of the earth’s outer layers

D．the heat given out by some radioactive elements

小题3:According to the passage,which of the following is NOT true?

A．The farther down,the hotter the earth gets.

B．The rock deep in the earth is liquid.

C．When the pressure releases from the earth’s crust,the rock melts.

D．Rock would be melted at 4 000°.
