flooding，causing millions of dollars in property damage and leaving thousands homeless.The floodwaters also poured vast amounts of raw sewage(未经净化的污水) into the rivers and streams that flow into Narragansett Bay.It sounds like the makings of an environmental nightmare，but in fact its just the opposite.To scientists delight，the sewageloaded floodwaters have caused a welltimed growth of phytoplankton，the microscopic creatures that form the foundation of marine(海洋的) food chains.With more food available for fish，clams and other sea creatures，the bays fisheries industry is expected to benefit.In decades past，Narragansett Bay typically experienced a late winter/early spring algal(海藻) bloom that fed creatures up and down the water column.But in recent years，the waters of Narragansett Bay have warmed greatly，interrupting this seasonal event.Mark Berman，an oceanographer with the National Marine Fisheries Service，said the flood seemed to have sent the bay back to its normal state.However，local，state and federal officials in Rhode Island have been battling other algal blooms that，by contrast，are causing widespread harm to the Narragansett Bay ecosystem.During summer months，sewage and agricultural runoff flows into the bay，causing large blooms.But instead of becoming food for sea creatures，much of the phytoplankton is consumed by bacteria，which grow fast in the warmer waters.The rapid bacteria growth leads to hypoxiaa decrease of oxygen in the water that can cause large fish kills.One such dieoff occurred in 2003，when millions of oxygenstarved fish washed up on the beaches of Narragansett Bay.The floods positive impact will probably be a onetime event，Mr. Berman said.Meanwhile，efforts to curb the harmful summer blooms continue；in 2008，for instance，Providence completed a $359 million sewage tunnel under the city designed to reduce the polluted storm overflow into Narragansett Bay.1Scientists believe that the raw sewage flowing into the bay will_.Apollute the islands environmentBcause lots of property damageCincrease the fisheries productionDdestroy the food chains in the bay2The potential benefit of fisheries industry relies on the_.Awarm temperatures of the bayBgrowth of phytoplanktonClarge summer alga bloomsDconsumption of oxygen by bacteria3People struggle against the summer blooms because they will_.Apollute the local natural environmentBincrease the production of fishery industryCcause large fish kills of the bay indirectlyDprovide too much food for sea creatures4It can be inferred that_.Amoney spent on the summer blooms has been wastedBthe government is investing to promote the local fisheriesCresearch of oceanology should be encouragedDopinions on the raw sewage impact are currently contradictory5The underlined word “curb” in the last paragraph can be defined as “_”Acontrol BconsumeCcause Dcure1run vi.跑；参加赛跑；(液体等)流生义：vt.开动(机器)；经营；管理Do you run the trains on oil or by steam?你们的火车用柴油发动还是用蒸汽推动？The

which或省略三种形式；destroy破坏(严重不能使用)；ruin使毁灭(无使用价值)；damage损害，损坏(可以再修复)，此处意为“对环境的损害”，故选D项。2D句意为：我们今天还是按照我们一贯的辩论程序进行。normal正常的；ordinary平常的，普通的；common常见的；usual通常的，往常的。故选D项。3B句意为：这种做法将导致今后存活下来供我们食用的鱼的数量会越来越少。left为过去分词作后置定语修饰fish，与其逻辑主语fish构成动宾关系，故选B项。4D考查不定式作定语。live为不及物动词，不能直接跟表地点的名词，此时只能用live on，故D为正确答案。5A句意为：目前的世界人口与1800年相比已经增长了六倍。grow by增长了。后面从句中缺少表语，只有what才能充当，that/which不可，故选A项。6Asee sb. as.把某人看作；look up to sb. as.把某人尊称为；see off送行；look down upon/on sb.看不起某人。只有A项从句意和结构上符合，故选A项。7B第一个空考查what引导的主语从句，what作say的宾语；第二个空考查that引导表语从句时，that不可省略；表语从句中having worked.，为分词作状语；I know后面又跟一个that(可省略)引导的宾语从句作kno
