4．Man is a land animal，but he is also closely tied to the sea．Throughout history the sea has served the needs of man．The sea has provided man with food and a convenient way to travel to many parts of the world．Today，nearly two-thirds of the world's population live within 80kilometers of the sea coast．
In the modern technological world，the sea offers many resources to help mankind survive （=continue to live）．Resources on land are beginning to be used up．The sea，however，still can be hoped to supply many of man's needs．
The list of riches of the sea yet to be developed by man's technology is impressive．Oil and gas explorations have been carried out for nearly 30years．Valuable amounts of minerals exist on the ocean floor ready to be mined．
Fish farming promises to be a good way to produce large quantities of food．The culture of fish and shellfish （貝類動物） is an ancient skill practised in the past mainly by Oriental people．
Besides oil and gas，the sea may offer new sources of energy．Experts believe that the warm temperature of the ocean can be used in a way similar to the steam in a steamship．Ocean currents （水流） and waves offer possible use as a source of energy．
Technology is enabling man to explore ever more deeply under the sea．The development of strong，new materials has made this possible．
The technology to harvest the sea continues to improve．Experts believe that by the year 2000the problems that prevent us from exploiting fully the food，minerals，and energy sources of the sea will be largely solved．

6．The major things that the sea offers man areD．
A．fish and oil                    
B．minerals and oil
C．warm temperature and ocean currents
D．the food，energy sources，and minerals
7．The sea serves the needs of man becauseD．
A．in provides man with food              
B．it offers oil to man
C．it supplies man with minerals            
D．a(chǎn)ll of the above
8．We can conclude from this passage thatB．
A．the sea resources have largely been used up
B．the sea，in the broad sense，has not yet been developed
C．the problems that prevent us from using the food，minerals，and energy sources of the sea have already been solved．
D．by the year 2000，the technology will be good enough to exploit all the sea resources
9．The underlined words Oriental people in the fourth paragraph probably meanA．
A．the people in Asia                  
B．African people
C．European people                   
D．American people
10．The best title for this passage isA．
A．Sea Harvest                       
B．Sea Food
C．Technology for Exploiting the Sea     
D．Man and the Sea．

9．It's well-known that meditation （冥想） has many benefits，but do you know how to practice it for a beginner？
Set a proper scene
Find a space for meditation．It should be private and quiet．Make sure the temperature is comfortable．Sit on a cushion （墊子） if the floor is uncomfortable．You may play soft music if you like．
                                 ．
Take a moment to loosen up．Remember that the goal of meditation is to relax．Loosen your clothing，remove your shoes and have a good stretch．Do your best to ease any muscle tension that might keep you from achieving relaxation．Make an effort to relax your facial muscles．
Focus on your breath
Sit down in the space you've prepared．Close your eyes and breathe．Each time you breathe in，count"one"．Each time you breathe out，count"one"．The idea is to strengthen being in the moment-the last breath doesn't matter，and the next one doesn't matter； only this one matters．
Feel your breath inflate （脹大） your lungs and push on your diaphragm （隔膜）．Feel how sweet it is to inhale the fresh air．As you do this，your body will gradually begin to relax and all of your attention will be centered within your mind．
Return to real life
Once you feel fully centered in your mind，allow yourself to gradually drift back to real life．Move your fingers and toes and slowly wake your body up．Open your eyes and remain there for a few minutes until your senses come back，and then slowly stand up．
Even if you can't make it fully into your mind，you still get some benefits from it．If you want to feel better，you just need to practice．Set about 10 minutes around the same time every day and repeat this exercise．

25．The text is aboutD．
A．the best way to stay relaxed           
B．tips on how to breathe slowly
C．the benefits of practicing meditation 
D．steps in practicing meditation for beginners
26．Which of the following can best fill in the blank？C
A．Forget yourself．
B．Avoid being disturbed．
C．Prepare yourself for it．
D．Pay attention to your inner self．
27．The underlined word"inhale"in the text can be replaced by"B"．
A．look for         B．take in        C．keep away           D．think of 
28．To gain greater benefits of meditation，beginners are advised toA．
A．practice it in a daily basis           B．listen to some popular music
C．do some exercise in advance            D．spend a long time in practicing it．

14．There are many animals in the world which are facing in the situation of disappearing．Two-thirds of the world's polar bear population could be gone by 2050if predictions（預(yù)測）of melting sea ice come true，the US Geological Survey reported on Friday．
The fate（命運） of polar bears could be even worse than that estimate（估計），because sea ice in the Arctic（北冰洋）might be disappearing faster than the available computer models predict，the geological survey said in a report aimed at determining whether the big white bear should be listed as a threatened species（瀕危物種）．
"There is a definite（確定的）link between changes in the sea ice and the welfare（利益） of polar bears，"said Steve Amstrad，who led the research team．He says Arctic sea ice is already at the lowest this year and is expected to retreat（退卻） farther this month．
That means that polar bears-some 16，000of them--will disappear by 2050from parts of the Arctic where sea ice is melting most rapidly，along the north coasts of Alaska and Russia，researchers said in a telephone briefing（簡報）．Other polar bears could survive beyond that date but many of those could be gone by 2100，Amstrad said．By this century's end，the only polar bears left might live in the Canadian Arctic islands and along the west coast of Greenland（格陵蘭島）．"It is likely to result in loss of approximately（大約）two-thirds of the world's current polar bear population by the mid 21st century，"the report's executive summary said．
"Because the observed trajectory（軌跡）of Arctic sea ice decline appears to be underestimated by currently available models，this assessment of future polar bear status may be conservative（保守的）．"In January，the US Fish and Wildlife Service proposed listing the polar bear as a threatened species，noting polar bears depend on sea ice as a platform to hunt seals（海豹），their main food．Without enough sea ice，polar bears would be forced onto land，but they are poor hunters once they get out of the water and ice，the researchers said．The bears'disappearance would probably take place as young cubs（幼獸）failed to survive to adulthood and females were unable to reproduce successfully．
9．What was the US Geological Survey intended to do？A
A．To determine whether the polar bear was in danger．
B．To measure how fast the sea ice melts in the Arctic．
C．To check the predictions of the computer models．
D．To find out the exact number of the polar bear．
10．What causes the polar bears to disappear by 2050？B
A．The pollution of the Arctic region．
B．The sea ice melting at high speed
C．Fewer food sources being left．
D．The temperature getting colder．
11．The key to preventing polar bears dying out seems toC．
A．help young polar bears to survive the cold winter
B．have large number of seals living in the oceans
C．make sure there is enough sea ice in the Arctic
D．provide chances for adult polar bears to reproduce．
