13．---Is there a flight to Paris this evening？
---There ________ be．I'll phone the airport and find it out．（　　）
A．mustB．willC．mightD．can

分析 --今天晚上有航班到巴黎吗？
--可能有．我马上就打电话到机场看看有没有．

解答 答案：C．
must必须，应该，一定，准是；will 表示愿意；can 表示能力、客观的可能性、请示和允许；might表示允许、许可，表示可能性的推测，含有"或许、大概、可能"之意．根据"I'll phone the airport and find it out．"可知这里并不确定，应该是表推测"可能有"，故用might，所以选C．

点评 本题考查情态动词的用法．要理解句意，掌握好各个情态动词的用法．充分利用语境，注意分清各个情态动词适用的句型，得出答案．

1．Across countryside，non-food crops are growing alongside wheat．Some are used in new alternatives to plastics and other materials，but others will simply be burned．
Burning crops is becoming more popular because it is good for the planet．Doing so is also cheaper than burning fossil fuels．As more land is devoted to non-food crop production，the economics of crops for fuel are likely to become even more favorable．
Humans have been burning such biomass-organic materials from plants or animals-since they discovered fire．But that burning fossil fuels could have catastrophic consequences has brought biomass back into fashion．
Even allowing for emissions（排放） of carbon dioxide from fuel used in planting，harvesting，processing and transporting biomass fuel，replacing fossil fuel with biomass can typically reduce greenhouse gas emissions by more than 90per cent．
Power stations around the world are experimenting with forms of biomass to add to their coal or oil，with encouraging results．Indeed，power companies could profit by turning to biomass，especially when the subsidies（补助） many governments offer for using renewable energy are taken into account．
Farmers can benefit from growing biomass．In Europe，the reduction of subsidies for certain crops is exposing farmers to market forces．Instead of being paid for whatever they produce，farmers must seek a clear demand for their product．Many believe that the demand for alternatives to fossil fuels could be just such a driver．
But while biomass offers a variety of potential alternatives，the world's infrastructure（基础设施） has developed around burning fossil fuels to such a stage that switching to biomass involves a change in conception that many companies have not accepted．
Also，there are problems with using biomass．Although most coal-fired power stations could take a small amount of their fuel from biomass without significant adjustment，few are built to run on biomass alone．Burning some forms of biomass also causes environmental problems．Oils and waste can be smelly，while wood produces smoke unless burned properly．
The supply chains for fossil fuels are set up well，but those for biomass are just the beginning．Sources of supply for biomass rely on farm production and can therefore be less reliable．They are necessarily limited and it wouldn't make sense to turn a very large amount of valuable agricultural land away from food crops．But as the world adjusts to the need to control greenhouse gas emissions，these problems may receive more attention．

A．It is a useful way of burning crops．
B．It is a new alternative to be used widely．

5．Walking outdoors is of greatbenefit（益处）to our health．
15．Two-thirds of the world's major rivers have now been disrupted（中断）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，c    B．c，e    C．b，e   D．b，c

  A．find more places to lay their eggs    B．face a more dangerous living habitat

  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．
