You may have heard of the book Moby Dick(《白鲸记》),written by the American author Herman Melville.You may also know that Moby Dick is considered one of the greatest novels ever written.However,it might surprise you to find out Herman Melville was not always a highly regarded author.

Melville’s first two novels,Typee and Omoo,were widely read and financially successfully.They were both exciting tales of adventures at sea and experiences with people in foreign lands.Melville became quite famous.However,upon the publication of his third book,Mardi,Melville’s popularity began to weaken.He was no longer interested in telling tales of pure adventure,and his writing took on a style that alienated(使疏远)the general reading public of his time.

Melville published Moby Dick in October of 1851 it was an original novel,combining aspects of sociology and philosophy,which confused readers by its complex symbolism.The book sold poorly.

Melville’s next book,Pierre,was almost completely disregarded by the public.Debt frustration and ill health finally forced Melville to take a low-paying job as a customs inspector.Eventually,Melville abandoned prose(散文)and began to write poetry.

The Civil War is the main subject of Melville’s poetry.He and his brother made a trip to the front line,and he published a book of poems,Battle-Pieces and Aspects of War,based on this experience.

Melville died in 1891 at the age of 72 at this point,his work had been completely forgotten by the public.His talent was to go unrecognized for the next thirty years.Then,in 1920s, his reputation began to improve as critics and readers rediscovered his work.Today Moby Dick is one of the best-known novels ever penned by an American author.

1.What were Melville’s first two novels mainly about?

A. His travel experience.

A. The main works of Melville. B. The skills in Melville’s writing.

C. The ups and downs of Melville. D. The reason for Melville’s failure.

Following news of the potential for life on the recently-discovered TRAPPIST-1 system, there may be another competitor ready to take its place.

With the help of the Cassini spacecraft, NASA (National Aeronautics and Space Administration) scientists have picked up the first evidence that chemical reactions are taking place deep below the surface of Enceladus, Saturn’s (土星的) sixth-largest moon. This means that there could be life in Enceladus’ warm underground seas.

An early study found that liquid oceans exist miles below Enceladus’ surface. But to reveal what is happening down there, scientists must rely on the plumes (股) of water that spray (喷射) through cracks in Enceladus’ icy surface. In October 2015, NASA sent Cassini into a deep dive into one of the plumes.

Cassini’s findings, published on April 13 in the journal Science, showed that hydrogen (氢) not only exists on Enceladus, but is also responsible for a chemical reaction between hot rocks and water in the ocean beneath its surface.

This same process on Earth provides energy for entire ecosystems around volcanic vents (火山口). There, tiny creatures are able to survive without sunlight, using hydrogen and carbon dioxide as fuel in a process known as “methanogenesis (甲烷生成)”.

The discovery of this chemical energy source on Enceladus means it could be a very good candidate to host life.

“Confirmation (确认) that the chemical energy for life exists within the ocean of a small moon of Saturn is an important milestone (里程碑) in our search for habitable (可居住的) worlds beyond Earth,” Linda Spilker, Cassini project scientist at NASA, told the Daily Mail.

Alien life was once only thought possible on habitable planets within the “Goldilocks zone” – far enough from our sun not to be a fireball, but not so far as to be freezing.

Research on Enceladus is still in its early stages, but the recent findings have important meanings for future exploration.

“At present, we know of only one genesis (诞生) of life, the one that led to us,” David Rothery, professor of planetary geosciences (行星与地球科学) from the Open University in the UK, told The Telegraph.

“If we knew that life had started independently in two places in our solar system, then we could be pretty confident that life also got started on some of the tens of billions of planets and moons around other stars in our galaxy,” he said.

1.What is the article mainly about?

A. The connection between the TRAPPIST-1 system and Enceladus.

B. The potential for life on Saturn’s moon, Enceladus.

C. The chemical energy source on Enceladus.

D. Scientists’ constant search for life in the solar system.

2.Scientists assume that there could be life on Enceladus because ______.

A. there is evidence of a warm ocean under Enceladus’ surface

B. hot rocks and water have been discovered on Enceladus

C. hydrogen discovered on Enceladus could be a chemical energy source

D. the entire ecosystems of Enceladus are somewhat similar to those of Earth

3.According to David Rothery, the recent findings on Enceladus could mean that ______.

A. there is only one genesis of life in our galaxy

B. there could be many habitable planets, but all in the “Goldilocks zone”

C. it won’t be long before scientists find a habitable planet beyond Earth

D. alien life could exist on some other planets if it existed on Enceladus

“One thing I enjoy about my job is that I can work on something that is actually active,” says Game McGimsey, an American volcanologist (火山学家). Part of his job includes keeping an eye on Alaska's many active volcanoes and giving people a heads-up when a volcano might erupt (喷发).

Like most jobs in the sciences, volcanology requires a lot of education. McGimsey received an undergraduate degree in geology at the University of North Carolina, then landed an internship (实习期) with a geologist at the USGS (美国地质勘探局) whose area of expertise was volcanoes. After earning a graduate degree at the University of Colorado, McGimsey accepted a job with the USGS and has been with the Alaska Volcano Observatory for 25 years.

Volcanoes can influence the world in ways we might not think about. For example, on Dec. 15, 1989, a 747 jetliner (a large airplane) flew through a thick ash (灰) cloud produced by Mount Redoubt, an Alaskan volcano that hadn't erupted in 25 years. The ash caused all four engines to die, and the plane's electronics went dead.

“The plane was within several thousand feet of flying into the mountains below when the pilots got a couple of the engines restarted and landed safely in Anchorage,” McGimsey says. It cost nearly $80 million to repair the damage to the plane.

Such situations show just how dangerous volcanoes can be. However, volcanologists know the risks and are prepared to protect themselves.

“There is certainly a higher danger level in volcanology than some other jobs,” McGimsey admits. “We understand how serious the danger is, and we don't like taking unnecessary chances. We avoid getting too close to an erupting volcano, because it's not worth injury or death simply to get a rock or a photograph.”

1.Before working for the USGS, McGimsey _____.

A. had been a pilot for 25 years

B. knew nothing about the organization

C. had taught at the University of North Carolina

D. had studied at the University of Colorado

2.On Dec. 15, 1989, a 747 jetliner _____.

A. had all its engines restarted

B. flew into a volcano in Europe

C. survived an air accident luckily

D. disappeared in a huge ash cloud

3.What McGimsey says in the last paragraph shows his _____.

A. pride B. carefulness

C. loneliness D. doubt

4.What would be the best title for the text?

A. Game McGimsey: a man of his word

B. Game McGimsey: a volcano watcher

C. The eruption of Mount Redoubt

D. Lost land of the volcano
