Ⅲ.阅读理解(每小题2.5分，共20分) A Whether you consider yourself a foodie or not，food is part of your daily routine.Also，food has a way of bringing people together.It is the focus of celebrations.George Bernard Shaw said it well：“There is no love sincerer than the love of food.” Many of us have traveled and tasted the world’s cuisine while watching Anthony Bourdain’s No Reservations or Parts Unknown or the energetic Peter Maneas in his show My Greek Odyssey.Following in their footsteps，the next best thing is to go on a culture & culinary(烹饪的) vacation.Not only will you get to try mouth-watering dishes，but you’ll also get to know more about the local culture and how it influences the cuisine. Local cuisine gives people an identity.Years ago，I was visiting Vienna with a group of friends.And one of them insisted on checking out the only restaurant in town serving Romanian food，just “like at home”．People who identify with traditional dishes from their home countries often come to this kind of restaurant as it feels like their “home away from home”． Food reflects people’s opinions on life.Greeks have strong ties among the community.Mezedes，a collection of small dishes served as appetizers(开胃菜)，are shared among the diners.The stories told over tzatziki，spanakopita，and dolmades create lifetime memories.Italians have great respect for their food and often talk about it.They also don’t mind spending a lot of time in the kitchen.Family meals are often joyful events with piles of dishes being served during an entire afternoon. Food helps you discover other languages.People across the world love to gather around the table.Preparing the foods and eating also spark great conversations.It’s the best opportunity to learn how to correctly pronounce foreign-language menu items.Knowing the local language will not only help you immerse(沉浸) in the culture but also build a hefty vocabulary! 1．Why does the author mention George Bernard Shaw in paragraph 1? A．To show people’s great love of food. B．To give an introduction to his works. C．To stress his achievements in drama. D．To explain the social influence of food. 答案　A 解析　推理判断题。根据第一段尤其是“There is no love sincerer than the love of food.”可知，作者在第一段中提到George Bernard Shaw是为了表明人们对食物的热爱。故选A。 2．What does the example in paragraph 3 imply? A．Eating habits vary around the world. B．People take pride in their local food. C．People prefer foreign food to traditional food. D．The same food you eat in a different place tastes different. 答案　B 解析　推理判断题。根据第三段“Local cuisine gives people an identity...People who identify with traditional dishes from their home countries often come to this kind of restaurant as it feels like their ‘home away from home’．”可知，第三段讲述的是当地美食赋予人们身份认同感，所以第三段中的例子表明人们对自己家乡的传统菜肴感到自豪。故选B。 3．What is paragraph 4 mainly about? A．Food brings neighbors together. B．Greeks have strict table manners. C．Food shows people’s way of life. D．Cultural differences affect family meals. 答案　C 解析　段落大意题。根据第四段首句“Food reflects people’s opinions on life.”并结合后面不同国家的例子可知，第四段主要讲述了食物反映人们对生活的看法，即食物反映人们的生活方式。故选C。 4．What does the underlined word “hefty” in the last paragraph probably mean? A．Scientific. B．Passive. C．Limited. D．Large. 答案　D 解析　词义猜测题。根据画线单词前几句“Food helps you discover other languages...It’s the best opportunity to learn how to correctly pronounce foreign-language menu items.”可知，这样可以建立“大的、丰富的”词汇量。故选D。 B When preparing fruit and vegetables，many people will peel(削皮) them.But often，it’s not necessary. Fruit and vegetables are rich sources of nutrition like vitamins.Not consuming enough of these nutrient-rich foods is linked to an increased risk of diseases.Eating 400g of fruit and vegetables a day，as the WHO recommends，is difficult to achieve for many people.So could consuming fruit and vegetable peels help with this issue by adding important nutrients to people’s diets? They can certainly contribute.For example，nutritionally important amounts of vitamins and minerals are found in the peels of seven root vegetables：beetroot，field mustard，wild carrot，sweet potato，radish，ginger and white potato.And the US Department of Agriculture shows that unpeeled apples contain 15% more vitamin C,267% more vitamin K,20% more calcium and 85% more fibre than peeled apples. Another reason is the effect on the environment.According to the UN’s Food and Agriculture Organization，uneaten food，including peels，generates 8%－10% of the world’s greenhouse gas emissions.New Zealand alone reports an annual wastage of 13,658 tonnes of vegetable peels and 986 tonnes of fruit peels. Given the nutrient content of peels and its contribution to food waste，why do people peel fruit and vegetables at all? Some must be peeled as the outer parts don’t taste nice，are hard to clean or cause harm.Also，peeling may be a necessary part of the recipe，for example，when making mashed potato.But many peels，such as carrot and kiwifruit，are suitable to be eaten，yet people habitually peel them anyway.Some people peel fruit and veg because they are concerned about pesticides(杀虫剂) on the surface. If you want to find out more about fruit and vegetable peels and what to do with it，there is lots of advice online including help on how to deal with peels.With a little investigation and creativity，you can help to reduce waste and increase your fruit and vegetable intake. 语篇解读　本文是一篇议论文。文章提出处理水果和蔬菜的时候没有必要去皮的观点，并分析了原因和给出了建议。 5．Where is the text most probably taken from? A．A cooking guidebook. B．A life magazine. C．A poster about environment. D．An ad about a health website. 答案　B 解析　文章出处题。根据第一段“When preparing fruit and vegetables，many people will peel(削皮) them.But often，it’s not necessary.”可知，本文是关于生活方面的常识，所以最可能选自生活杂志，故选B。 6．How can eating fruit and vegetable peels benefit people’s health? A．Not eating the peels will lead to higher risks of some diseases. B．Some significant vitamins and minerals are only found in peels. C．Eating peels can increase people’s intake of important nutrients. D．Peels have more nutrients than fruit and vegetables’ inner parts. 答案　C 解析　推理判断题。根据第三段中“And the US Department of Agriculture shows that unpeeled apples contain 15% more vitamin C,267% more vitamin K,20% more calcium and 85% more fibre than peeled apples.”可知，吃果皮可以增加人们重要营养素的摄入量，故选C。 7．What is the author’s purpose in mentioning New Zealand? A．To highlight the serious food problem in the country. B．To draw our attention to greenhouse gas emissions. C．To call on New Zealanders not to throw away peels. D．To show peels’ negative impact on the environment. 答案　D 解析　推理判断题。根据第四段内容，尤其首句可推知，作者提到新西兰的目的是表明果皮对环境的负面影响。故选D。 8．Why do so many people peel carrots? A．Because some recipes tell them to do so. B．Because the outer parts are hard to clean. C．Because there exists too much pesticides. D．Because they’re used to peeling vegetables. 答案　D 解析　细节理解题。根据倒数第二段中“But many peels，such as carrot and kiwifruit，are suitable to be eaten，yet people habitually peel them anyway.”可知，很多人削胡萝卜皮是因为他们习惯于削皮，故选D。 Ⅳ.七选五(每小题2.5分，共12.5分) Why Is Eating Colourful Food Good for You? Most of us are faced with the same choice numerous times a day：what to eat.Along with price，accessibility and preference，we’ll often use a food’s healthfulness to help us make a decision. 1 It’s widely accepted by researchers that we need a varied diet. 2 The proof may be in the Mediterranean diet，which contains a lot of fruit，vegetables and healthy fats such as extra virgin olive oil，and is frequently rated the healthiest diet by scientists. Eating lots of colours may lower your risk of missing out on all vital nutrients.“If we’re missing a colour of the rainbow，we may be missing a function of that food，” says Minich.This is because plant foods contain thousands of natural compounds，which have anti-inflammatory(抗炎的) benefits. 3 Blue and purple foods，including blueberries，have a high content of the plant anthocyanin(花青素)，which has been linked to lowering the risk of heart disease and type 2 diabetes. A research fellow at Harvard TH Chan School of Public Health says eating a colourful diet can also help people avoid possible side effects of eating too much of one food.“ 4 For example，research has found that orange juice is associated with a lower risk of cognitive decline，but too much intake is associated with type 2 diabetes，” she says. Eating a rainbow diet may also be complex. 5 We could tie ourselves in knots.We also need to eat from other food groups to get all the nutrients we need，such as protein. A．Food is very complex. B．A varied diet is packed with different vegetables. C．It could be really tricky to get every colour every day. D．But how do we know we’re getting enough nutrients? E．Different coloured foods come with different benefits. F．However，is colour the best guide to getting all the nutrients? G．And one way to do this is by eating all the colours of the rainbow. 1．答案　D 解析　根据上文“Along with price，accessibility and preference，we’ll often use a food’s healthfulness to help us make a decision.”可知，接下来作者要介绍如何选择食物。选项D“但是，我们如何知道我们获取了足够的营养呢？”和上文意思一致。故选D。 2．答案　G 解析　根据上文“It’s widely accepted by researchers that we need a varied diet.”可知，这一段指出，我们需要丰富多元的饮食。选项G“做到这的一个方法是通过吃彩虹颜色的食物”和上文意思一致。G项中的this指代了本段第一句中的a varied diet，实现了照应，而空后句中的proof也照应了本空中提出的一种方案。故选G。 3．答案　E 解析　根据下文“Blue and purple foods，including blueberries，have a high content of the plant anthocyanin(花青素)，which has been linked to lowering the risk of heart disease and type 2 diabetes.”可知，本段列举了蓝色和紫色食物如何对人体有益的例子，故本段的主题句应该陈述不同颜色的食物对人体有不同的好处。选项E“不同颜色的食物有不同的好处”和下文意思一致。故选E。 4．答案　A 解析　根据下文“For example，research has found that orange juice is associated with a lower risk of cognitive decline，but too much intake is associated with type 2 diabetes”可知，研究发现，橙汁可以降低认知能力下降的风险，但是摄入太多会导致二型糖尿病。这说明我们不能用一个标准来衡量食物。选项A“食物是非常复杂的”和下文意思一致。故选A。 5．答案　C 解析　根据上文“Eating a rainbow diet may also be complex.”和下文“We also need to eat from other food groups to get all the nutrients we need，such as protein.”可知，每天吃遍每一种颜色的食物也是很难办到的，而且也要摄取其他食物中的营养。选项C“要每天都弄到每一种颜色的食物可能很困难”和上下文意思一致。故选C。 Ⅴ.语法填空(每小题1.5分，共15分) A recent report shows an amazing 400 percent year-on-year increase in global durian(榴莲) demand because of the 1. (prefer) of Chinese consumers.China now plays a key role in the market,2. (consume) as much as 91 percent of global durian.Over the past two years，imports of durian 3. (reach) an amazing $6 billion.
