1. With me is Mr Lin Shuiqing, from the Society for Environmental Preservation, and Mr Qian Liwei, an economist.(L5--6)
[分析]
1） 句子结构分析：本句为倒装句。主语是Mr Lin Shuiqing and Mr Qian Liwei，句首的with me作表语；2. There are many factories and industries which control the amount of pollution they produce, and are very careful to spend money …(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factories and industries；定语从句的谓语是两个动词短语control the amount和are very careful；而每个动词短语中又各自带有一个定语从句，即they produce修饰pollution，they cause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there be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there stands / appears / belongs / comes / exists / lives / lies / follows等。同时， there be中还可插入情态动词，如there ought to / has to / seems to be等。其反意疑问句的构成有：aren’t / isn’t there; don’t / doesn’t there等。如：There lived an old man named Wang Lin here in the past, didn’t there?3. What I’m here to say is that having worked side by side with many environmentalists , I know that a healthy environment and a stable economy should be possible at the same time. (L36)
[分析]
1） 句子结构分析：本句是一个多重复合句。What I’m here to say是主语从句；2） 语言知识分析：having done 为V-ing形式的完成式，表示它的动作发生在主句谓语动词的动作之前。如：Having finished his homework, he went to play football with his friends. 高考链接
1. It is obvious that you are very concerned about the present situation of our environment. (L29)
[考点] situation
[考例] The collapse of the World Trade Centre has put US economy in a difficult _____. (上海2003春)
A. occasion B. case
C. situation D. background[点拨] 选C。句意为：世贸中心的倒塌将美国经济置于非常艰难的境地（situation）。occasion场合，机会；case情形，情况，案例；background背景。4. What we need is more effective laws to preserve the environment, which still allow the economy to grow. (L47—48))
[考点] what引导的主语从句。[考例] After Yang Liwei succeeded in circling the earth, _____ our astronauts desire to do is walk in space.（上海2004）
where B. what
C. that D. how [点拨] 选B。在这个句子中，After Yang Liwei succeeded in circling the earth是时间状语从句；后面的主句中，what our astronauts desire to do是主语从句，walk in space 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。Word guessingmake bigger or wider in size, volume, or
