The measures were carried out by some governments,including nets and traditional drum lines,and provided tour- ists 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 wild- life was clear.Researches desire for non- deadly shark control measures such as ecobarriers,which physically separate swimmers 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-re- lated 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 with- out nets on the NSW north coast over the past two years. The Human Society International's head of campaigns,Nicola Beynon,said ·205 课时作业兰 and Thinking(Ⅱ) 间 纠错空间 the government needed to move away from outdated methods."Deadly shark nets and drum lines are more than 50 years behind scientific and animal welfare standards for dealing with marine wild- life,”said Beynon. The NSW Greens'marine spokes- man,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 observation towers for our lifeguards and improving the beach devices." 1.Which of the following do researchers 方法总结 focus on? A.Beachgoers'safety. 1方1中1为员”为1中员 B.The shark-related death rate. C.Friendly shark control ways. D.Advanced shark-spotting techniques. 2.What is Paragraph 4 mainly about? A.Shark-related deaths.

B.A new study on sea animals C.Shark net programs D.Effective ways of avoiding sharks 世五维课堂 B (2022·山东新泰一中高二月考)Re cently a team of scientists produced a re- 纠错空间 port about global warming and the natu- ral world.They wanted to find out if global warming was dangerous for plants and animals.The scientists were sur- prised by what they found.They saw that during the next 50 years about 25% of land animals and plants will disappear from the earth.More than 1 million plant and animal species will die out by 2050. The head of the research team, Christ Thomas,who is a professor of conservation biology at Leeds University, said the results of their research were frightening.More than 10%of all plants and animals will disappear from the earth.It 方法总结 is too late to save many plants and animals because of the greenhouse gases that are al- ready in the atmosphere.But the scien- tists say if we control greenhouse gases now,we can save many more plants and animals from disappearing. The scientists studied some areas of the world with very rich biology.These areas were Europe,Australia,Central and South America,and South Africa. Their studies showed that species living in mountainous areas had a better chance of survival because they could move uphill to get cooler.In flat areas,such as des- erts,plants and animals would have to move very long distances to get cooler,so they were in great danger of dying out. The scientists found many surprising things.For example,they found that half of the 24 species of butterflies they stud- ied in Australia would soon disappear. ·20 英语·选择性必修第三册 5.To many plants and animals,what can global warming be best described as? A.Deadly. B.Surprising. C.Disappointing.D.Frightening. 6.What's the purpose of the research led by Christ Thomas? A.To protect animals and plants from global warming. B.To call on people to control green- house gases. C.To study the effect of global war- ming on animals and plants. D.To warn us of the dying out of many animals and plants. 7.What can we learn from the passage? A.About 25%of land animals and plants have disappeared from the earth. B.In about three decades more than 1 million plant and animal species will die out. C.We can do nothing to save the plants and animals. D.Wildlife in flat areas can't find enough food. 8.Which can be the best title for this pas- sage? A.Extinct animals in the world B.Disappearance of butterflies C.The impact of global warming on plants and animals D.A frightening discovery concerning global warming Ⅱ.阅读填句 For most Americans,plastic bags are a necessary part of any shopping trip.1 But plastic bags that end up in oceans and on beaches are harmful to fish,birds and other wildlife.Several cities around the 6 UNIT 3 ENVIRONMENTAL PROTECTION U.S.have either banned single-use plas- tic bags,taxed them,or found other ways to limit their use.Those who sup- port a bag tax say it encourages people to bring reusable bags.2 But critics ar- gue that taxing the use of plastic bags puts unfair stress on low-income families. Here two students share their views. Grant Gordinier,11,from San Die go,California,says,"3 Every year, 485 billion plastic bags are not recycled. Some end up in the ocean and can cause harm to sea life.Placing a small tax on plastic bags might encourage shoppers to bring their own reusable bags to stores. Reusable bags would cut down on waste in the environment.Businesses would al- so save money by not having to provide as many plastic bags to customers. However,Elle Belperio,12,from Los Angeles,California,has different opinions."4 Some grocery stores have bins for shoppers to recycle used bags. Other stores reward individual efforts. They give a small refund(退款)every time a shopper uses his or her own bag. If you reuse and recycle your plastic bag properly,you will not be hurting the en- vironment.I know many families reuse them to pick up after their dogs.5 In- stead,the government should educate people in ways to reuse and recycle them. A.New York City will also ban plastic bags. B.There are many ways to reuse plastic bags. C.In my home,we find many uses for the bags. ·20 课时作业乡 D.Besides,they think it helps cut down on waste. 空 间 E.Communities should limit the use of plastic bags. 纠错空间 F.I don't think communities should tax plastic bags. G.Many people seldom think of the bags' influence on the environment.
