Sean wrote a letter to his state representative(州议员)，David Nangle，asking him to introduce a law that would ban(禁止) shark finning in their state.In his letter，Sean included a painting of a shark with its fin removed.
After a few tries，he was able to speak to Representative Nangle who agreed to propose
the bill(提出此项议案).In June，2014 it became a law! Massachusetts is now one of the 10 states in America that ban shark finning.Sean is also now interested in helping protect sea turtles in his home state.And guess what Sean wants to be when he grows up.A shark biologist(生物学家) of course!
Sean's actions show how young people can make a big difference.His advice to other children is，“If you are interested in something and if you believe you can do it，you should

One possible version：
Air Pollution
The air is badly polluted around us.Because Our cities has many factories that burn
coal.Every year these factories pour a large amount of black smoke into air.Besides there are more cars in cities now.
There are some methods to solve the problem.First of all，we should ask the factories to stop giving out black smoke into air.Next，we'd better ride bikes or walk instead of driving to school.The advantages of bike riding or walking are that it's good for health and it doesn't cost anything.What's more，it's a good idea to plant more trees and flowers.Planting trees not only makes air cleaner，but also makes our environment more beautiful.Finally，we need to recycle books and paper and stop using paper napkins.That can help us cut down fewer and fewer trees.
I think everyone should play a part in solving the air pollution.I'm sure that our actions
can make a difference and lead to a better future.
Unit5 单元语法小专题(Grammar Focus) 语法精讲 一般现在时的被动语态 1.主动语态与被动语态 语态是英语句子中表明句子主语与谓语之间动作关系的一个概念，具体分为主动语态与被动语态两种。 主动语态表明的是“句子谓语动作是由主语发出，即主语是谓语动作的执行者”这一主谓关系。而被动语态表明的则是“句子谓语动作不是由主语发出的，主语反而是谓语动作的承受者”这一主谓关系。如: Many people speak English.许多人讲英语。(主动语态，主语“Many people”是谓语动作“speak”的执行者) English is spoken by many people.英语被许多人讲。(被动语态，主语“English”是谓语动作“is spoken”的承受者) 2.一般现在时的被动语态 一般现在时的被动语态其谓语结构为:am/is/are＋及物动词的过去分词 (1)肯定句结构为:主语＋am/is/are＋及物动词的过去分词＋其他。如: Farm machines are made in that factory.农场机械是在那个工厂被制造的。 (2)否定句结构为:主语＋am/is/are＋not＋及物动词的过去分词＋其他。如: Farm machines are not made in that factory.农场机械没有在那个工厂被制造。 (3)一般疑问句结构为:Am/Is/Are＋主语＋及物动词的过去分词＋其他。如: Are farm machines made in that factory？农场机械是在那个工厂被制造的吗？ 注意: ①happen，belong to，have，cost，last，own，stay等一般不用被动语态。 ②taste，sound，prove，feel，look，smell等系动词常用主动形式表示被动意义。除此之外，read，sell， wash，write等动词用来说明主语的性质特征时，也常用主动形式表示被动意义。 语法精练 Ⅰ.用括号内所给单词的适当形式填空。 1.English ________(learn) as a foreign language in most of Chinese schools. 2.The dogs ________(take) good care of by my mother. https://www.doczj.com/doc/da1724318.html,ually，my homework ________(not do) in the afternoon. 4.________ the flowers ________(water) every day? https://www.doczj.com/doc/da1724318.html,puters ________(not sell) well in that shop. 6.________ our school ________(visit) by many people every day? 7.Three languages ________(use) in this country. 8.The workers ________(make) to work 12 hours every day. 9.Such exercises ________ often ________(do) by the students in class. 10.The car ________ always ________(clean) by Mr. Zhang in the morning.
