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, a study has
found .
The measures camed out by some govemments, including nets and traditional drum lines,
provided beachgoers with a false sense of safety. The study found the effectiveness of nets was
difficult to evaluate, 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
separate swimmers from sharks, sonar 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. Similarly, 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 govemment
needed to move away from outdated methods. "Deadly shark nets and drum lines are more than 50years 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 intothe shark net program should be directed to observation towers for our lifeguards and improving the beach devices."
30. Which of the following do researchers focus on?
A. Beachgoers' safety.
B. Friendly shark control ways.
C. The shark-related death rate.
D. Advanced shark-spotting techniques.
31 . What is the main idea of Paragraph 4?
A. Shark-related deaths.
B. Measures to protect sharks.
C. Reasons for using shark nets.
D. Dangers for beachgoers.
32. What do Nicola Beynon and Justin Field have in common?
A. Science is developing too fast.
B. Observation towers need rebuilding.
C. Many people are drowned every day.
D. No shark nets are to be used.
33. What can be the best title for the article?
A. Are Shark Nets Necessary?
B. A New Study on Sea Animals
C. Shark Net Programs
D. Effective Ways of Avoiding Sharks
30．【答案】B。解析：细节题。根据第二段中的“Researchers desire for non-deadly shark control measuressuch as eco barriers…”可知．B项正确，A、C、D三项均不是研究人员关注的焦点。故本题选B。
31．【答案】C。解析：主旨题。根据题干定位到第四段。本段开头就点明主旨“One of the arguments insupport of using shark nets is…”，后面利用数据对比进一步解释使用防鲨网的原因。故本题选C。
32．【答案】D。解析：推断题。根据第五段中Nicola Beynon和第六段中Justin Field的原话可知，D项“不应再使用防鲨网”是这二人共同的观点。A项是对Nicola Beynon的观点的过度推断，B、C两项是对JustinField的观点的过度推断。故本题选D。
33．【答案】A。解析：主旨题。文章第一段首句“Shark netsin place across Australia specifically in NewSouth Wales (NSW) and Queensland,to protect beachgoers should be dropped as they have caused more harm thangood”点明主旨——防鲨网弊大于利应该弃用，后面的内容也都是围绕此主题展开。A项“防鲨网是必要的吗？”能概括文章主旨．B、C、D三项均不能概括文章主旨。故本题选A。
