,Iknowthatahealthyenvironmentandastabledevelopment

shouldbepossibleatthesametime在整个句子中作表语。在表语从句中，thatahealthyenvironmentanddevelopmentshouldbepossibleatthesametime是that引导宾语从句作know宾语；havingworkedwithmanyenvironmentalconsultants是-ing分词短语在表语从句中作状语。整个句子意思为：在这里我想说是,与很多环境顾问一起工作之后，我知道健康环境和稳定经济并存是可能。2）语言知识分析：havingdone为V-ing形式完成式，表示它动作发生在主句谓语动词动作之前。如：Havingfinishedhishomework,hewenttoplayfootballwithhisfriends.3.Therearemanyfactoriesandindustrieswhichcontroltheamountofpollutiontheyproduce,andareverycarefultospendmoneyrepairinganydamagetheycause.[分析]1）句子结构分析：这个句子比较复杂，在这个句子中，which引导一个定语从句修饰factoriesandindustries；定语从句谓语是两个动词短语controltheamount和areverycareful；而每个动词短语中又各自带有一个定语从句，即theyproduce修饰pollution，theycause修饰damage。经过分析可以看出，整个句子意思为：有许多工厂和行业，他们一方面控制生产污染量，其次花钱来修复他们所引起损害。2）语言知识分析：在therebe句型中，be形式由最靠近be名词数决定。比较：a.Thereisablackboardandfiftydesksandchairsintheclassroom.b.Therearefiftydesksandchairsandablackboardintheclassroom.[拓展]在therebe句型中，除了能够使用系动词be以外，还能够使用其它一些动词，如therestands/appears/belongs/comes/exists/lives/lies/follows等。同时，therebe中还可插入情态动词，如thereoughtto/hasto/seemstobe等。其反意疑问句组成有：aren’t/isn’tthere;don’t/doesn’tthere等。如：TherelivedanoldmannamedWangLinhereinthepast,didn’tthere?高考链接1.Itisclearthatyouareveryconcernedaboutthepresentsituationofourenvironment.[考点]situation[考例]ThecollapseoftheWorldTradeCentrehasputUSeconomyinadifficult_____.(上海春)A.occasion B.case C.situation D.background[点拨]选C。句意为：世贸中心坍毁将美国经济置于非常艰难境地（situation）。occasion场所，机会；case情形，情况，案例；background背景。2.Whatweneedarebetterlawstopreservetheenvironmentandstillallowourcountrytogrow.(P23)[考点]what引导主语从句。[考例]AfterYangLiweisucceededincirclingtheearth,_____ourastronautsdesire
