Question

   It seems we can 't get on the planet last enough. Two thirds of NAS As money is spent on manned space exploration,and that number will grow with the USA’s decision to send a man to Mars in 2037. We've seen all there is to see on Earth,right? Wrong. The final place is here,under the surface of the sea.

     Heading down into the ocean,human limits are quickly reached. At 200 metres,the water is as black as a moonless night. Most nuclear submariries (核潜艇) woutb implode (内爆) before they reach 1 km down. At 3 km — still less than the average depth of the ocean — there's a good chance that you’ 11 discover a new species. The deepest-diving whales go no further. At the very bottom,about 11 km down,lies the Challenger Deep,the deepest part of the Mariana Trench in the Pacific Ocean. Eighteen humans have walked on the Moon,but only three have seen the Deep with their own eyes.

     Yet things live down there. Big things. A very loud sound was once heard and scientists suggested that it was produced by an animal bigger than a blue whale,the largest creature known on the planet.

     In the late 1990s,a deep-water submarine vas dropped in the Southern Ocean,and passing 1,000 metres,it discovered something huge assing under it. Surprised? Don't  be. The ocean :overs 70% of the planet's surface and we’ve itudied less than 5% of it. We know more about he dark side of the Moon than about the bottom the sea.

One reason that we explore space is to find evidence of other life forms. The search for life outside of Earth is important,but robots can look inder the dry rocks of Mars better than humans,rhey’ re absolutely important for doing ocean esearch too,but they can't look under the sea. rhe cost of exploration is rising,but the results kvould benefit all our lives. Understanding the  ceans will help us find new sources of food,drugs and energy.

    Perhaps now it's time to begin a new period df sea exploration. Manned exploration of space is fiction(科幻小说)Theadventure of the ieep sea is science fact.

6. What do the examples in Paragraph 2 suggest?

   A. Sea exploration is no easy task.

   B. Nuclear submarines need to be improved.

    C. The ocean is far deeper than people expected.

   D. The condition under the sea is similar to that on the Moon.

7. What do we know about the Challenger Deep?

   A. Blue whales live there.

   B. No one has ever been there.

   C. People are terrified by the sight of it.

   D. It is the deepest known location 6n Earth.

8. What does the author think of the discovery in the Southern Ocean?

   A. It's surprising.     B. It's no wonder.

   C. It's worrying.      D. It's no success.

9. Why do we need to explore the sea?

   A. Sea exploration is cheaper than ever before.

   B. We have explored less than 5% of the sea.

   C. It will help improve our future life.

   D. It will benefit space exploration.

10. What does the author want to tell us?

   A. Space exploration is of little,value.

   B. We spend too much money on space travel.

   C. Humans’ success lies in how much they explore the sea.

   D. The ocean is the place where we should make our efforts.

Answer 1

6. A.推理判断题。第二段列举各个深 度海洋的情况是为了说明海洋探索不 是一件容易的事。

7. D.细节理解题。根据第二段中的 the Challenger Deep,the deepest part of the Mariana Trench in the Pacific Ocean可知，挑战号深渊是地球上目 前已知的最深的海底。

8. B.推理判断根据第四段中的 Surprised? Don't be. The ocean covers 70% of the planet's surface and we’ve studied less than 5% of it. We know more about the dark side of the Moon than about the bottom of the sea 可推测，作者认为南冰洋中可能存在比蓝 鲸更大生物的发现不足为奇。

9. C.细节理解题。根据倒数第二段中的the results would benefit all our lives. Understanding the oceans will help us find new sources of food,drugs and energy可知，海洋探索将造福人类。

10. D.主旨大意题。作者在文章第一 段就点出自己的观点：The final place is hdre,under the surface of the sea,并在接下来的段落中具体论述 海洋探索的重大意义。由此可知，D 项概括了文章主旨。
