last month in Rhode Island led to widespread flooding，causing millions of dollars in property damage and leaving thousands homeless.The floodwaters also poured vast amounts of raw sewage(未經(jīng)凈化的污水) 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；參加賽跑；(液體等)流生義：vt.開動(dòng)(機(jī)器)；經(jīng)營；管理Do you run the trains

which或省略三種形式；destroy破壞(嚴(yán)重不能使用)；ruin使毀滅(無使用價(jià)值)；damage損害，損壞(可以再修復(fù))，此處意為“對(duì)環(huán)境的損害”，故選D項(xiàng)。2D句意為：我們今天還是按照我們一貫的辯論程序進(jìn)行。normal正常的；ordinary平常的，普通的；common常見的；usual通常的，往常的。故選D項(xiàng)。3B句意為：這種做法將導(dǎo)致今后存活下來供我們食用的魚的數(shù)量會(huì)越來越少。left為過去分詞作后置定語修飾fish，與其邏輯主語fish構(gòu)成動(dòng)賓關(guān)系，故選B項(xiàng)。4D考查不定式作定語。live為不及物動(dòng)詞，不能直接跟表地點(diǎn)的名詞，此時(shí)只能用live on，故D為正確答案。5A句意為：目前的世界人口與1800年相比已經(jīng)增長(zhǎng)了六倍。grow by增長(zhǎng)了。后面從句中缺少表語，只有what才能充當(dāng)，that/which不可，故選A項(xiàng)。6Asee sb. as.把某人看作；look up to sb. as.把某人尊稱為；see off送行；look down upon/on sb.看不起某人。只有A項(xiàng)從句意和結(jié)構(gòu)上符合，故選A項(xiàng)。7B第一個(gè)空考查what引導(dǎo)的主語從句，what作say的賓語；第二個(gè)空考查that引導(dǎo)表語從句時(shí)，that不可省略；表語從句中having worked.，為分詞作狀語；I know后面又跟一個(gè)that(可省略)引導(dǎo)的賓語從句作kno
