,Iknowthatahealthyenvironmentandastabledevelopment

shouldbepossibleatthesametime在整個句子中作表語。在表語從句中，thatahealthyenvironmentanddevelopmentshouldbepossibleatthesametime是that引導賓語從句作know賓語；havingworkedwithmanyenvironmentalconsultants是-ing分詞短語在表語從句中作狀語。整個句子意思為：在這里我想說是,與很多環(huán)境顧問一起工作之后，我知道健康環(huán)境和穩(wěn)定經(jīng)濟并存是可能。2）語言知識分析：havingdone為V-ing形式完成式，表示它動作發(fā)生在主句謂語動詞動作之前。如：Havingfinishedhishomework,hewenttoplayfootballwithhisfriends.3.Therearemanyfactoriesandindustrieswhichcontroltheamountofpollutiontheyproduce,andareverycarefultospendmoneyrepairinganydamagetheycause.[分析]1）句子結構分析：這個句子比較復雜，在這個句子中，which引導一個定語從句修飾factoriesandindustries；定語從句謂語是兩個動詞短語controltheamount和areverycareful；而每個動詞短語中又各自帶有一個定語從句，即theyproduce修飾pollution，theycause修飾damage。經(jīng)過分析可以看出，整個句子意思為：有許多工廠和行業(yè)，他們一方面控制生產污染量，其次花錢來修復他們所引起損害。2）語言知識分析：在therebe句型中，be形式由最靠近be名詞數(shù)決定。比較：a.Thereisablackboardandfiftydesksandchairsintheclassroom.b.Therearefiftydesksandchairsandablackboardintheclassroom.[拓展]在therebe句型中，除了能夠使用系動詞be以外，還能夠使用其它一些動詞，如therestands/appears/belongs/comes/exists/lives/lies/follows等。同時，therebe中還可插入情態(tài)動詞，如thereoughtto/hasto/seemstobe等。其反意疑問句組成有：aren’t/isn’tthere;don’t/doesn’tthere等。如：TherelivedanoldmannamedWangLinhereinthepast,didn’tthere?高考鏈接1.Itisclearthatyouareveryconcernedaboutthepresentsituationofourenvironment.[考點]situation[考例]ThecollapseoftheWorldTradeCentrehasputUSeconomyinadifficult_____.(上海春)A.occasion B.case C.situation D.background[點撥]選C。句意為：世貿中心坍毀將美國經(jīng)濟置于非常艱難境地（situation）。occasion場所，機會；case情形，情況，案例；background背景。2.Whatweneedarebetterlawstopreservetheenvironmentandstillallowourcountrytogrow.(P23)[考點]what引導主語從句。[考例]AfterYangLiweisucceededincirclingtheearth,_____ourastronautsdesire
