1 句子结构分析 本句为倒装句 主语是MrLinShuiqingandMrQianLiwei 句首的withme作表语 2 Therearemanyfactoriesandindustrieswhichcontroltheamountofpollutiontheyproduce andareverycarefultospendmoney L38 39 分析 1 句子结构分析 在这个句子中 which引导一个定语从句修饰factoriesandindustries 定语从句的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 通过分析可以看出 整个句子的意思为 有许多工厂和行业 他们一方面控制生产的污染量 另一方面花钱来修复他们所引起的损害 拓展 在therebe句型中 除了可以使用系动词be以外 还可以使用其他一些动词 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 其反意疑问句的构成有 aren t isn tthere

Whatweneedismoreeffectivelawstopreservetheenvironment whichstillallowtheeconomytogrow L47 48 考点 what引导的主语从句 考例 AfterYangLiweisucceededincirclingtheearth ourastronautsdesiretodoiswalkinspace 上海2004 whereB whatC thatD how 点拨 选B 在这个句子中 AfterYangLiweisucceededincirclingtheearth是时间状语从句 后面的主句中 whatourastronautsdesiretodo是主语从句 walkinspace是表语 因为系动词前面有实意动词do 所以省略系动词后面的to Wordguessing
