Language tips
1. The majority of people in the town want to encourage new industry in the area.城里大多数人都希望促进这一地区工业的发展。

2. I think our manager will persuade the government to let him build a new factory. 我想经理会说服政府让他建新厂的。
persuade意思是：说服；劝导；使相信: 1)跟带to的不定式: I have persuaded him to give up smoking.我已说服了他戒烟。2)跟into+分词和名词：I persuaded him into doing it.我说服他去做这件事。He tried to persuade her but failed.他试图说服她，但是没有成功。3)跟that从句: I persuaded Robert that the journey was too dangerous and he didn't go.我对罗伯特说那个旅行太危险，他被说服了，所以没有去。

4. In the greenhouse, computer controls the watering of the plants as well as the light and the temperature. 在温室里，计算机既控制作物的灌溉，还控制光照和温度。

My English teacher can speak Japanese as well as French. =My English teacher can not only speak French but also Japanese.(两句重点都在Japanese上) 另外，当as well as连接两个主语时，谓语动词跟前一个主语一致，而not only…but also…连接两个主语时，则根据就近原则: My friend as well as his parents is going to California. Not only you but also he is wrong. as well 用于句末时，相当于too,意为“也”。如：She is not only a good teacher, she is a good mother as well.他不但是个好老师，还是个好妈妈。

9. At present, many people in western countries spend too much money on new possessions that they do not need, such as lots of new clothes.
spend、cost和take这三个词都有“花费”的意思，它们的用法各自有其特点。cost的主语必须是物；spend的主语必须是人，而且spend常用于spend…on sth.这一结构中。take常用于it take sb.… to do sth.这个结构。例如：She spent a lot of money on books.她花了很多钱来买书。Her books have cost her a lot of money.她的书花了很多钱。It takes her a lot of money to buy these books.那些书花了她很多钱。
