7.In the past decade the popularity of rock climbing has greatly increased,and so has the number of injuries.It has been estimated that rock climbing is now enjoyed by more than 9million people in the US each year.Study findings revealed a 65percent increase in the number of patients that were treated in US emergency departments for rock climbingrelated injuries between 1991and 2008.
The study,published in the online issue of the American Journal of Preventive Medicine,found that about 40,000patients were treated in US emergency departments for rock climbingrelated injuries between 1991and 2008.The most common types of rock climbingrelated injuries were fractures (骨折) and sprains (扭傷).The ankle was the most common body part to be injured (40percent).Climbers in the study ranged in age from 2to 74,with an average age of 26.The study also found that women took up a quarter of the injuries.
Falls were the primary reason for injury with over threequarters of the injuries occurring as the result of a fall.The severity of fallrelated injuries had a lot to do with the height of the fall.Patients who were injured after falling from a height over 20feet were 10times more likely to be treated than patients who were injured falling from 20feet or lower.
"We found that the climbers who fell from heights higher than 20 feet took up 70 percent of the patients treated for a rock climbingrelated injury,"explained the study author Lara McKenzie,PhD,director at the Center for Injury Research and Policy at Nationwide Hospital."This trend,combined with the fact that rock climbers have a higher hospitalization rate than other sports and recreational injuries,demonstrates the need to increase injury prevention efforts for climbers."

26.Which body part is most likely to get injured for a climber?B
A.The arm.  B.The ankle.  C.The knee.  D.The hand.

15.Two-thirds of the world's major rivers have now been disrupted(中斷)with more than 50,000 dams in an attempt to stole water and provide power.In the US,there are more than 85,000 dams,disrupting large and small rives,and in most cases transforming natural flow.The most famous of these,the Hoover Dam,constructed in the l930's,is mainly responsible for the fact that the Colorado River no longer reaches the ocean.
    Dams,besides all their attractive benefits,also have negative impacts.Creating a reservoir means a large area must be flooded.Communities may lose their land,houses and culturally impotent sites.
    Environmentally,the new reservoir can be a paradise for wildlife,especially birds.However,it can cause greenhouse gas emissions(排放)and poison the water for fish.Also,the dramatic rise and fall of water levels during dam releases is too extreme for plains and animals to cope with,resulting in dead zones around the shores of reservoirs.Fish that lay their eggs in the shallows,for example,may find a few hours later that those sites are high and dry.
    Dams don't just block water flow.They also prevent fish migrations,and are a barrier to sediment (沉淀物)flows.Instead of rushing downriver,sediments get backed up against the dam wall,which cause the reservoir level to increase over time.However,sediments which are rich in nutrients have become a problem.The fertility of the entire system can be influenced,with soils lost during seasonal rains not being replaced.
     Perhaps the biggest problem can be seen in deltas(三角洲),often host to large cities,which are sinking into the oceans.Groundwater is being extracted to feed the city,causing the urban weight to sink and sediments washed away by the ocean are no longer being replaced.The result is that sea level rise in cities from Shanghai to Alexandria.
51.What effects does creating a reservoir have on people's life?D
  a.People will see fewer birds near the rivers.
  b.Farmers below the dam may have less water to irrigate their fields
  c.Visitors can't see some cultural relics anymore.
  d.More conflicts and wars over water will break out
  e.More kinds of fish will become extinct in the future
  A.a(chǎn),c    B.c,e    C.b,e   D.b,c
52.With many dams built across rivers,fish willB
  A.find more places to lay their eggs    B.face a more dangerous living habitat
  C.feed on more sediment rich in nutrients D.find it easier to deal with the rise of water
53.How can dams influence the cities like Shanghai?C
  A.Its entire system will be influenced.    B.The rainy season will last longer.
  C.It will lie below sea level in the future   D.Rich soils will be washed away
54.What does the text mainly talk about?A
  A.Environmental loss of dams.B.Cultural loss of dams
  C.Economical gain of dams      D.Environmental benefits of dams
55.Where can we most probably read this passage?C
    A.In a travel magazine     B.In a personal diary
    C.In a science report       D.In a biology textbook.

19.When I agreed to stage-managed my school's production of Guys and Dolls,I had no idea of(61)what a stage manager actually did.Still,I (62)decided(decide) that it would be a(n)(63)interesting (interest)experience,and a way to get involved with theater.Besides,if there was already a director and some technicians to build the sets and run lights,how much could there be (64)left(leave)for a stage manager to do?I figured that I would spend a lot of time(65)on rehearsals(彩排)and scripts(劇本).
