限时规范练30(必修5Unit 15B)核心素养关键词:培养学生人与社会、关注饮食健康的素养能力意识一、阅读理解AMany people believe eating healthily is expensive — and more costly than buying junk foods.But our new research,published 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.“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.,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.“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.,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。

BNew 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 thekiwi,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。
