2、 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

3、 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

4、 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

5、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 food

6、s 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.1.What did the researchers find?A.Australians have a preference for sweet foods

9、advantages of a healthy diet.BNew Zealand has a pest problem.The country has a plan to solve it.The countrys 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.

10、When they were introduced to the islands environment,the rats ateand,scientists believe,finally killed offseveral bird species.Humans also brought other mammals,like stoats and possums.Stoatswhich are similar to weaselswere introduced to eat another invasive mammal population:rabbits.Instead,the sto

11、ats 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

12、 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 Zealands birds are close to dying out.Killing predatory mammals is not new for New Zealand

13、.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 wi

14、ll 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 its 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.”5.What is t

15、he purpose of New Zealands plan?A.To save native birds.B.To drive mammals away.C.To do research on pests.D.To control rabbit population.6.Why were possums introduced to New Zealand?A.To kill rabbits.B.To make money.C.To protect forests.D.To catch weasels.7.What does the underlined word “flourish” in

25、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.D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.A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.B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 woul

26、d 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.C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。【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.A推理判断题。根据第一段中的“The countrys leaders want to kill rats and other predatory mammals by 20

27、50.”及第四段中的“As a result,several of New Zealands 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.B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.A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

28、数量又开始增长起来。8.B推理判断题。根据最后一段中的“I really do think its possible”可知,Russell对政府的这项计划充满信心。二、【篇章导读】本文是记叙文。作者开车途中为了保持清醒让儿子不断与她交谈,这一路的交谈也让作者对儿子有了更多的了解。1.B通读全文可知,经过一路的交谈,作者对儿子有了更多的了解,所以此处指作者觉得自己整天唠叨孩子们,却不“了解(knowing)”他们。2.D由最后一段中的“But I knew that I had taken the first step toward changing”可知,作者通过路上和儿子聊天对儿子有了更多的

29、了解,之后,她懂得了如何更好地爱孩子。本句作者的收获和上一句作者认为自己不够了解孩子构成转折关系,故用转折连词But。3.C这次家庭聚会给作者提供了重要的“经验(lesson)”。4.A由下文中的“at the wheel”和“as I drove down”可知,作者一家开“车(car)”去参加家庭聚会。5.D根据上下文语境可知,作者和丈夫“轮换(take ones turn)”开车。6.D由下文中的“My son,full of energy,was wide awake”可推断,丈夫和女儿“睡(slept)”着了。7.B作者在夜晚开车,因此“需要(needed)”保持清醒。8.C由下文中

30、的“I asked him to talk to me”可知,作者不想通过“播放(play)”收音机使自己清醒。9.C上文中的“to stay awake”对本空有提示。10.A由下文作者的回答可知,此处作者的儿子问她想“讨论(discuss)”什么。11.D由下文作者的儿子引出话题可知,作者愿意谈论“任何(anything)”她的儿子想谈论的话题。12.B由本句中的“for the next hour or so we talked about”可知,作者认为这个话题很“好(fine)”。13.C由本句中的“frogs and toads”以及生活常识可知,这里谈论的是它们的“不同(diff

31、erences)”。14.B由本句中的“basketball and soccer”可知,此处谈论的是两个“运动(sports)”项目。15.A根据上下文语境可知,儿子对谈论球星的话题很“感兴趣(interested)”。16.B由本句中的“but wed continue to talk”可知,作者的儿子有时候会暂“停(stop)”谈话。17.A根据上文中的“we were on a late night family”可知,作者开夜车,行驶在“黑暗的(dark)”道路上。18.D由本句中的“the bright lights woke everyone”可推断,作者一家“到达了(arriv

32、ed)”目的地。19.C由下文中的“But I knew that I had taken the first step toward changing”可知,虽然谈话的魔力“消失(disappeared)”了,但作者收获了很多,并且开始改变。20.B作者通过一路上和儿子的交谈,听儿子谈论他所感兴趣的话题,对儿子有了更多的了解,同时,作者也改变了自己以前不良的“倾听(listening)”习惯。三、第二句:women woman第三句:were was;where when第四句:去掉第一个the第五句:has had第六句:wanted后加to;but and / so第七句:some any第八句:complete completely第十句:difficulty difficult
