   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.

     The mystery of why humans are the only animals to have chins (下巴) may have been solved by scientists who suggest that it is connected to the invention of cooking.

    A paper from the University of Florida tries to explain exactly why humans 一 unlike all other primates (灵长目动物) 一have chins.

     A team led by Dr James Pampush collected information from more than 100 kinds of primate and compared it with historical information. Computer modelling found how the chin developed.

    Random genetic change(随机的基因变化)was ruled out because the chin developed 77 times faster than the average genetic change. And the study finds no evidence that it -served a useful purpose. The research,published in the Journal of Human Evolution,suggests the chin is a by-product of another event. In this case,the event could well be the invention of cooking.

     “The chin began to appear as a result of major changes six million years earlier. The arrival of cooking and softer food meant humans no longer needed big teeth and powerful jaws .and over the next two million years to 200,000 years both got smaller and the chin was bora ,” said Dr Pampush. “My guess is that it most likely happened around two million years ago when there was a jump in brain size. The changes which finally lead to the chin are directly related to cooking,and indirectly related to larger brains and bodies."

     Dr Pampush's new theory goes against previous suggestions that the chin was an example of sexual selection,with attractive chins marking out men who are likely to make good mates(配偶) . The fact that both men and women have chins means the theory is unlikely.

     Another theory put forward in the past said that the chin was a way to balance out the stress of chewing,but Dr Pampush also threw doubt on that idea.

1. The reason why we have chins .

   A. is connected to humans’ action of chewing

   B. has something to do with cooking

   C. is random genetic change

   D. is related to eating time

2. How did the researchers get their result?

   A. By carrying out experiments. .

   B. By studying scientific theories.

   C. By examining the human brain.

   D. By comparing recorded information.

3. Before developing chins,humans .

   A. had bigger teeth

   B. cooked softer food

   C. had smaller jaws

   D. had larger bodies

4. According to Dr Pampush,the chin most

probably appeared around .

   A. 6 million years ago

   B. 4  million years ago

   C. 2  million years ago

   D. 0.2 million years ago

5. What does the underlined part “the theory” refer to?

   A. Men are likely to have more attractive chins.

   B. The chin helps humans attract a mate.

   C. Both men and women have chins.

   D. Dr Pampush's theory.

    Our class recently went on the. school trip to an adventure centre. It is locating not too far away from the school. It only took us two hours get there by bus. There were twenty of ourselves and we spend five days there on a sailing course. The activities were good organised but safety standards were high. We enjoyed the courses although the weather was bad. Each student was given a lot of personal attention,who helped them to develop their confidence. I believe this course was good for all the students,and I think the school should organise a more similar trip next year.
