12、ng at night in a dark sea.我们看见一个女人晚上在深色的海里游泳。分析：see a woman swimming (see+宾语+doing做宾补:“看见某人正在做事”)doing做宾补,表示与宾语之间是主动关系，且表示正在进行。【知识链接】see sb.do (与sb.是主动关系，动作完成)see sb./sth.done (表示与宾语是被动关系)【实战演练】a.I saw him going out when I came in.b.I saw him go out.c.I saw the boy beaten by his father just now.(2)S

13、he surfaces,cries in fear,and then disappears forever.(这个句子是3个并列谓语，正式的语法结构，do,do，and do。原文不太正式)她浮出水面，恐惧地叫喊，之后永远地消失了。【知识链接】容易与分词做状语混淆-看清结构与意义。a.He put on his coat,picked up his bag,and then went out.b.He went out,leaving the door open.(3)This is the opening scene from the 1975 film Jaws,showing a sha

14、rk attack.这是1975年电影大白鲨的开场镜头，展示了鲨鱼攻击的场景。把此句转变为定语从句做定语：This is the opening scene from the 1975 film Jaws,which shows a shark attack.(4)Jaws was a great success,attracting huge audiences and winning many awards.大白鲨大获成功，吸引了大批观众，赢得了许多奖项。attracting and winning 这一部分是现在分词做伴随状语。a great success 是抽象名词具体化，类似的词还

15、有failure,success,surprise,honor,comfort,pity(5)It strengthened peoples long-held idea of the great white shark as a dangerous animal.这加强了人们长期以来持有的大白鲨是种危险动物的认知观念。与strengthen类似的构词：shorten；broaden;widen;lengthen另一形式：enrich；encourage;enlarge(6)People have always been scared of sharks,but Jaws made thing

16、s worse.人们一直都害怕鲨鱼，但大白鲨让情况变得更糟糕。scare v.使害怕adj.scary令人害怕的;scared感到害怕的；短语：scare sb.away/off把吓跑be scared of 害怕Seeing the scary film,Linda was almost scared to death.(7)It made people frightened of sharks,especially of the great white shark.它使人们更加恐惧鲨鱼，尤其是大白鲨。make+宾语+形容词短语(过去分词形式的形容词)作宾补，表示宾语所处的状态。a.The

17、book made more and more children interested in reading.b.The boss made the workers finish the job within two days.c.He was made to solve the problem by himself.(8)At that time,nobody cared if sharks were killed,or how many were killed.People just want them killed.那时，没有人关心鲨鱼是否被杀了，以及有多少鲨鱼被杀了。人们只想要他们死掉

18、。care后接if引导的宾语从句；want+宾语+过去分词作宾补（与宾语之间是被动关系）医生们不在乎他们自己是否将被感染(infect)。他们想要病人们被拯救。Doctors dont care if/whether they will be infected.They want patients saved.(9)This was not only due to fear of sharks,but also finning.Finning is a type of fishing where sharks are caught and their fins cut off.这不仅是因为对鲨

19、鱼的恐惧，还因为割鳍。割鳍是一种捕鱼方式，在这种捕鱼方式中，鲨鱼被捕获，鱼鳍被割断。cut off:切掉；隔离；阻断；中断due to:由于 a.由于这场可怕的疾病，很多人被与外面的世界隔绝了。Due to the terrible disease,many people are cut off from the outside world.b.由于工人们的努力，他们减少了成本费。Due to the workers efforts,they cut down the cost.(10)The sharks are thrown back into the sea where they die

20、 slowly and painfully.鲨鱼被扔向海里，在那里它们缓慢而痛苦地死去.(11)Finning would have an unexpected effect on Peter,the man who wrote the book the film Jaws was based on.割鳍带给大白鲨的原著作者彼得.本奇利预料之外的影响。have an effect/impact on 对有影响 the man 做Peter的同位语，其后是个定语从句，在此定语从句内部，the book 后是省略which或that 的定语从句。(12)In 1980,Benchley was d

21、iving when he came across an awful sight.1980年，本奇力正在潜水，就在那时他看到了可怕的一幕。come短语：实现come true 出版 come out 形成 come into being 加油；快点；得了吧come on 提出 come up withsight短语:看见 catch sight of 第一眼at first sight 在视野外 out of sight 在视野内in sight 13.It was an area where fishermen were finning,and the sea floor was cover

22、ed with dead sharks.那是一片海域，渔民们正在这片海域采割鲨鱼的鱼鳍，海底遍布着鲨鱼的尸体。where 引导定语从句，在从句中作地点状语。14.Benchley saw sharks being killed and this caused a change in him.本奇利亲眼目睹鲨鱼被杀，这引起了他内心的深刻转变。15.He came to see people as a danger to sharks,rather than the other way round.他意识到人类才是鲨鱼的威胁，而鲨鱼并非人类的敌人。the other way round:反过来，反
