in the BMC Public Health,shows this isn’t the truth.‎ Most of the Australian family food budget is being spent on junk foods and drinks that are high in fat,sugar and salt.‎ Less than 7% of Australians eat healthily.The Australian adults get at least 35% of their energy from junk foods and drinks.As a result,two-thirds of adults (63%) and one-quarter of children are overweight.‎ We used the Australian Health Survey 2011-2013 and the suggestions of the Australian Dietary Guidelines to model healthy diets for a family of two adults and two children every two weeks.We collected food prices in supermarkets and stores in high- and low-socioeconomic (社会经济地位低的) areas in Brisbane,and compared the diet prices with family incomes.‎ In both areas,a family of two adults and two children spend about 18% more on present diets than would be required to buy healthy diets.About 58% of the food budget for present diets is spent on junk foods,including takeaway foods (14%),and sugary drinks (4%).‎ In the low-socioeconomic area,a family of two adults and two children spend $640.20 every two weeks on their present diets,but could buy a healthy diet for $560.93 every two weeks.In the high-socioeconomic area,these numbers are $661.92 and $580.01.‎ Supermarket food prices were about 3% higher in the high-socioeconomic location.Takeaway foods were also relatively more expensive,but sugary drinks were priced similarly in both areas.‎ Present diets cost more than healthy diets,so causes other than price must be helping to drive preferences for unhealthy choices.‎ ‎【篇章导读】本文是说明文。一项研究表明:健康饮食比垃圾食品的花费要更加便宜。‎ ‎1.What did the researchers find?‎ A.Australians have a preference for sweet foods.‎ B.Most Australian kids have fat problems.‎ C.Half Australians live on junk foods.‎ D.Most Australians eat unhealthily.‎ 答案D 解析细节理解题。根据第三段中的“Less than 7% of Australians eat healthily.”可知,大多数澳洲人饮食不健康。‎ ‎2.How did the researchers get the result?‎ A.By making a comparison.‎ B.By doing the study online.‎ C.By carrying out interviews.‎ D.By asking personal questions.‎ 答案A 解析细节理解题。根据第四段可知,研究者们通过使用来自Australian Health Survey的调查数据,然后搜集各超市的食品价格,最后再和家庭收入进行对比,得出研究结论。‎ ‎3.What can we learn from Paragraph 5?‎ A.Australian foods are healthier.‎ B.A healthy diet is actually cheaper.‎ C.Health foods are becoming more expensive.‎ D.People choose junk foods for their low prices.‎ 答案B 解析细节理解题。根据第五段中的“a family of two adults and two children spend about 18% more on present diets than would be required to buy healthy diets”可知,研究结果表明,垃圾食品的花费已经超过健康食品,健康食品其实更便宜。‎ ‎4.What might a following paragraph be about?‎ A.The harm of junk foods.‎ B.How we can eat healthily.‎ C.Why people choose junk foods.‎ D.The advantages of a healthy diet.‎ 答案C 解析推理判断题。根据最后一段可知,作者认为,目前人们在垃圾食品上的消费已经超过了健康食品,这说明人们选择垃圾食品不是因为价格,而是因为别的。由此判断接下来文章最有可能讨论人们选择垃圾食品的原因。‎ B New Zealand has a pest problem.The country has a plan to solve it.The country’s leaders want to kill rats and other predatory mammals (肉食性哺乳动物) by 2050.‎ In New Zealand,rats are an invasive species.Long ago,rats came to the country on boats,with humans,in the 13th century.When they were introduced to the island’s environment,the rats ate—and,scientists believe,finally killed off—several bird species.‎ Humans also brought other mammals,like stoats and possums.Stoats—which are similar to weasels—were introduced to eat another invasive mammal population:rabbits.Instead,the stoats fed on native species.Possums were brought to New Zealand for their fur.But their population also grew quickly out of control.Possums feed on the eggs and young of native birds.They also cause damage to forests.‎ One of the reasons invasive mammal populations grew so quickly is that New Zealand is home to almost no native mammals.Most of its native species are birds.Many of these birds,including the kiwi,cannot fly.That is a big problem for the birds.They cannot fly to safety.As a result,several of New Zealand’s birds are close to dying out.‎ Killing predatory mammals is not new for New Zealand.The country has killed off rats on some of its smaller islands.In those places,bird species that were in danger of dying out have begun to flourish.‎ New Zealand hopes to improve upon the methods used in those small areas.The government plans to spend more than $20 million on the project.The money will pay for research,technology,and tools to kill off the animals.‎ It is a big goal.But scientists say it can be met.“I really do think it’s possible,” says James Russell,a scientist at the University of Auckland in New Zealand.“It will require people working in every corner of the country.”‎ ‎【篇章导读】本文是说明文。文章介绍了新西兰为保护当地鸟类而采取的消除有害动物的措施。‎ ‎5.What is the purpose of New Zealand’s plan?‎ A.To save native birds.‎ B.To drive mammals away.‎ C.To do research on pests.‎ D.To control rabbit population.‎ 答案A 解析推理判断题。根据第一段中的“The country’s leaders want to kill rats and other predatory mammals by 2050.”及第四段中的“As a result,several of New Zealand’s birds are close to dying out.”可知,新西兰政府的这项计划旨在消灭境内的有害动物,保护当地的原生鸟类。‎ ‎6.Why were possums introduced to New Zealand?‎ A.To kill rabbits.‎ B.To make money.‎ C.To protect forests.‎ D.To catch weasels.‎ 答案B 解析细节理解题。根据第三段中的“Possums were brought to New Zealand for their fur.”可知,新西兰引进负鼠是为了从其毛皮上获取经济利益。‎ ‎7.What does the underlined word “flourish” in Paragraph 5 mean?‎ A.Increase.‎ B.Appear.‎ C.Change.‎ D.Drop.‎ 答案A 解析词义猜测题。根据第五段中的“The country has killed off...have begun to...”可知,新西兰的一些小岛已经消灭了所有老鼠,在那些地方,本来几乎灭绝的鸟类数量又开始增长起来。‎ ‎8.What is Russell’s attitude towards this plan?‎ A.He is against it.‎ B.He is confident of it.‎ C.He has doubts about it.‎ D.He shows no interest in it.‎ 答案B 解析推理判断题。根据最后一段中的“I really do think it’s possible”可知,Russell对政府的这项计划充满信心。‎ 二、完形填空 This is a real story about an old man in China.Sixty-three-year-old Zhuang Guorong is a 　1　 rural primary school art teacher,who has had a life of 　2　 for more

the receiver,it can be life-changing.‎ 答案 第一句:offered前加was;known→knowing 第二句:late→later;who→whom 第三句:do→did;去掉第二个a 第五句:hungry→hungrily;our→my 第六句:buying→buy 第七句:Kind→Kindness
