Language tips
1. The majority of people in the town want to encourage new industry in the area.城里大多數人都希望促進這一地區工業的發展。

2. I think our manager will persuade the government to let him build a new factory. 我想經理會說服政府讓他建新廠的。
persuade意思是：說服；勸導；使相信: 1)跟帶to的不定式: I have persuaded him to give up smoking.我已說服了他戒煙。2)跟into+分詞和名詞：I persuaded him into doing it.我說服他去做這件事。He tried to persuade her but failed.他試圖說服她，但是沒有成功。3)跟that從句: I persuaded Robert that the journey was too dangerous and he didn't go.我對羅伯特說那個旅行太危險，他被說服了，所以沒有去。

4. In the greenhouse, computer controls the watering of the plants as well as the light and the temperature. 在溫室里，計算機既控制作物的灌溉，還控制光照和溫度。

My English teacher can speak Japanese as well as French. =My English teacher can not only speak French but also Japanese.(兩句重點都在Japanese上) 另外，當as well as連接兩個主語時，謂語動詞跟前一個主語一致，而not only…but also…連接兩個主語時，則根據就近原則: My friend as well as his parents is going to California. Not only you but also he is wrong. as well 用于句末時，相當于too,意為“也”。如：She is not only a good teacher, she is a good mother as well.他不但是個好老師，還是個好媽媽。

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這三個詞都有“花費”的意思，它們的用法各自有其特點。cost的主語必須是物；spend的主語必須是人，而且spend常用于spend…on sth.這一結構中。take常用于it take sb.… to do sth.這個結構。例如：She spent a lot of money on books.她花了很多錢來買書。Her books have cost her a lot of money.她的書花了很多錢。It takes her a lot of money to buy these books.那些書花了她很多錢。
