Are Shark Nets Necessary?
为了防止鲨鱼对人类的攻击,一直以来澳大利亚的海岸线都设置防鲨网,但是研究发现该做法弊大于利。
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(声呐) 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The Humane Society International’s head of campaigns,Nicola Beynon,said the government needed to move away from outdated methods⑤.“Deadly shark nets and drum lines are more than 50 years behind scientific and animal welfare standards for dealing with marine wildlife,” said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.评估
③separate vt.分开
④similarly adv.相似地
⑤method n.方法
⑥observation n.观察
The study found the effectiveness of nets was difficult to evaluate,while the significant damage they cause to other marine wildlife was clear.
译文:研究发现,防鲨网的有效性很难评估,而它们对其他海洋野生动物造成的重大损害则是显而易见的。
分析:本句总体上是一个并列句。The study found是第一个分句,while the significant damage...是第二个分句。在第一个分句中the effectiveness of nets was difficult to evaluate是宾语从句,在第二个分句中they cause to...是定语从句。
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.
