Washington: NASA has announced evidence that Jupiter's largest moon, Ganymede, has a saltwater ocean under its icy surface. The ocean seems to have more water than all the water on Earth's surface, according to new Hubble observation.

New Hubble observations of Ganymede's magnetic field strongly suggest that the moon, which is the largest in our whole solar system, is home to a subsurface ocean.

Scientists estimate the ocean is 95 kilometres thick, which is about 10 times deeper than Earth's oceans. But unlike our salty waters, Ganymede's ocean is buried under 150 kilometres of ice.

While scientists have speculated(推测) since 1970s about the presence of an ocean on Ganymede------the largest moon in our solar system------ until now the only observational evidence came from a brief flyby by the Galileo spacecraft, which didn’t observe the moon long enough to confirm a liquid ocean.

This discovery marks an important milestone, highlighting what only Hubble can accomplish. In its 25 years in orbit, Hubble has made many scientific discoveries in our own solar system. A deep ocean under the icy surface of Ganymede opens up further exciting possibilities for life beyond Earth.

Scientists have already confirmed the existence of an ocean on Europe, another moon orbiting Jupiter, and NASA has announced plans to send an unmanned mission there searching for the life that might come with liquid water.

Hubble is a telescope that orbits Earth, but because of its impressive gravitational analyses it can be used to study the inside of far distant planets. Using these same principles, scientists could theoretically detect oceans on distant planets as well.

1.What can we learn about the Ganymede from the passage?

It is a planet with the largest moon in our whole solar system.

B. Its ocean adds to people’s excitement about life beyond Earth.

C. It will be used by NASA as a base for the Hubble telescope.

D. Its liquid ocean was first proved by the Galileo spacecraft.

2.Which of the following best describes the writer’s attitude towards Hubble?

A. Cautious B. Doubtful

C. Negative D. Favourable

3.What does the underlined part in Paragraph 6 mean?

An underground ocean has been found in Europe.

B. The presence of an underground ocean in Europe is not possible.

C. It is now certain that there is an ocean on Europe.

D. No evidence has shown the existence of an ocean on Europe.

4.What type of writing does this passage belong to?

A. A term essay

B. A news report

C. An experiment report

D. An exploration review.

The book’s first and third sections deal with the adventures of an Alabama boy, Raphael Semmes Cody, who goes by the name Raff. The boy grows up knocking around the Nokobee woods; he’s drawn to its natural wonders, and uses the forest to escape from his parents’ unhappy marriage. In the woods he leaves almost no stone unturned as he discovers the forest’s rich flora and fauna(动植物). Raff grows up and heads to Harvard to study law, but returns later in life to protect the Nokobee from crazy developers. But fans of Wilson’s science will be most interested in the book’s middle section, where the author inserts a mini-novel describing the trials and sufferings of the ants living in the endangered forest.

Reviews of the book have been mixed. Writing for The New York Review of Books, Margaret Atwood praised Wilson for his first novel, saying that it is highlighted by a diversity of ideas and an imaginative plot. And — with the exception of some dull preachiness(说教) — it is entertaining.

1.What can we learn from Edward O. Wilson’s joke?

A. He is unwilling to leave his childhood behind.

B. He is an excellent naturalist with a good reputation.

C. He has had a lifelong passion for insects.

D. He has the same hobbies as many children.

2.In Anthill, ant societies differ from the human ones in that _____________.

A. they are more likely to conduct wars

B. they practice agriculture

C. they are more selfless

D. they don’t care for their young

3.Which of the following statement is TRUE according to the passage?

A. Raff is in fact the author himself.

B. Wilson won two Pulitzer Prizes for fiction.

C. Atwood has a completely positive opinion of Anthill.

D. Anthill is set in the author’s home state.

4.What is the purpose of the passage？

A. To present Edward O. Wilson’s life story.

B. To present Edward O. Wilson’s achievements.

C. To show the readers that we can learn from ants.

D. To give an overview of a new book.

You never see him, but they're with you every time you fly. They record where you are going,how fast you're traveling and whether everything on your airplane is functioning normally. Their ability to withstand almost any disaster makes them seem like something out of a comic book.They're known as the black box.

When planes fall from the sky, as a Yemeni airliner did on its way to Comoros Islands in the India ocean June 30, 2009, the black box is the best bet for identifying what went wrong. So when a French submarine (潜水艇) detected the device's homing signal five days later, the discovery marked a huge step toward determining the cause of a tragedy in which 152 passengers were killed.

In 1958, Australian scientist David Warren developed a flight-memory recorder that would track basic information like altitude and direction. That was the first mode for a black box, which became a requirement on all U.S. commercial flights by 1960. Early models often failed to withstand crashes, however, so in 1965 the device（装置） was completely redesigned and moved to the rear of the plane – the area least subject to impact – from its original position in the landing wells (起落架舱). The same year, the Federal Aviation Authority required that the boxes, which were never actually black, be painted orange or yellow to aid visibility.

Modern airplanes have two black boxes: a voice recorder, which tracks pilots' conversations,and a flight-data recorder, which monitors fuel levels, engine noises and other operating functions that help investigators reconstruct the aircraft's final moments. Placed in an insulated ( 隔绝的) case and surrounded by a quarter-inch-thick panels of stainless steel, the boxes can withstand massive force and temperatures up to 2,000℉. When submerged, they're also able to emit signals from depths of 20,000 ft. Experts believe the boxes from Air France Flight 447, which crashed near Brazil on June 1,2009, are in water nearly that deep, but statistics say they're still likely to turn up. In the approximately 20 deep-sea crashes over the past 30 years, only one plane's black boxes were never recovered.

1.In Paragraph 1，the author wants to say the black box_________.

A. is an necessary device on an airplane

B. comes from a comic book

D. can control the function of an airplane

2.From the black box on the Yemeni airliner_________could be found.

3.Why was the black box redesigned in 1965?

A. New materials became available by that time.

B. The early models often got damaged in the crash.

C. Too much space was needed for its device.

D. The early models didn't provide the needed data.

4.The black boxes were painted orange or yellow to_________.

A. distinguish them from the colour of the plane.

B. warn people to handle them with care

C. make them easily identified.

D. obey the international standards.

5.What do we know about the black boxes from Air France Flight 447?

B. There is an urgent need for them to be reconstructed.
