Are Shark Nets Necessary?

為了防止鯊魚對(duì)人類的攻擊,一直以來澳大利亞的海岸線都設(shè)置防鯊網(wǎng),但是研究發(fā)現(xiàn)該做法弊大于利。

Shark nets in place across Australia,specifically in New South Wales(NSW) and Queensland,to protect beachgoers should be dropped as they have caused more harm than good.

The measures①were carried out by some governments,including nets and traditional drum lines,and provided beachgoers with a false sense of safety.The study found the effectiveness of nets was difficult to evaluate②,while the significant damage they cause to other marine wildlife was clear.Researchers desire for non-deadly shark control measures such as eco barriers,which physically separate③swimmers from sharks,sonar(聲吶) technology,and various shark-spotting techniques. 

Researchers said while the risk of coming across a shark was rare,any shark-related deaths and injuries caught huge public and media attention.

One of the arguments in support of using shark nets is that just one shark-related death has been reported in Queensland since the 1960s.Similarly④,since the 1930s,NSW has had only one shark-related death.But there have been at least 13 people killed by sharks at beaches without nets on the NSW north coast over the past two years.

The Humane Society International’s head of campaigns,Nicola Beynon,said the government needed to move away from outdated methods⑤.“Deadly shark nets and drum lines are more than 50 years behind scientific and animal welfare standards for dealing with marine wildlife,” said Beynon.

The NSW Greens’ marine spokesman,Justin Field,said,“People are 100 times more likely to drown at the beach than to be killed by a shark in Australia.Therefore,millions of dollars going into the shark net program should be directed to observation⑥ towers for our lifeguards and improving the beach devices.”

①measure n.措施

②evaluate vt.評(píng)估

③separate vt.分開

④similarly adv.相似地

⑤method n.方法

⑥observation n.觀察

典句欣賞

The study found the effectiveness of nets was difficult to evaluate,while the significant damage they cause to other marine wildlife was clear.

譯文:研究發(fā)現(xiàn),防鯊網(wǎng)的有效性很難評(píng)估,而它們對(duì)其他海洋野生動(dòng)物造成的重大損害則是顯而易見的。

分析:本句總體上是一個(gè)并列句。The study found是第一個(gè)分句,while the significant damage...是第二個(gè)分句。在第一個(gè)分句中the effectiveness of nets was difficult to evaluate是賓語從句,在第二個(gè)分句中they cause to...是定語從句。

理解誘思

1.What do researchers focus on?

答案:Friendly shark control ways.

2.What do Nicola Beynon and Justin Field have in common?

答案:No shark nets are to be used.
