D．Eating speed.‎ 解析：选D　细节理解题。根据第二段中的“splitting them into three categories based on how quickly they ate: slow, normal, and fast”可知，按照参与者吃饭的速度，研究者将他们分为吃得慢、正常、快三个类别。‎ ‎2．Which may be the result of the study?‎ A．Fast eaters are 4 times more likely to have metabolic syndrome.‎ B．Normal and slow eaters don't have metabolic illness.‎ C．89% of fast eaters have higher blood pressure.‎ D．Slow eaters are healthier than fast eaters.‎ 解析：选D　推理判断题。根据第三段最后一句“Fast eaters also saw more weight gain, larger waistlines, and higher blood sugar levels than slow eaters.”可知，比起吃得慢的人，吃得快的人体重增加更多、腰围更大、血糖水平也更高，反向推知，吃得慢的人比吃得快的人健康。‎ ‎3．What does the underlined word “gobbling ” in Paragraph 4 best mean?‎ A．Tasting slowly. B．Digesting quickly.‎ C．Eating greedily. D．Cooking carefully.‎ 解析：选C　词义猜测题。根据第四段中的“when people eat fast they are more likely to overeat”可知，吃得快可能会让人吃得过多。所以这个词的意思应是“狼吞虎咽地吃”，故选C项。‎ ‎4．What does the last paragraph tell us?‎ A．The importance of eating speed.‎ B．The advantage of eating slowly.‎ C．The result of a Chinese study.‎ D．Fast eating and overeating.‎ 解析：选B　段落大意题。根据文章最后一段的中心句“Previous research backs up the weight benefits of slow eating, too.”及下文内容可知，本段主要讲慢点吃的好处。‎ Ⅱ.阅读七选五 ‎(2019·湖南长郡中学检测)We eat in our cars, at our desks, on the go, and in front of the TV.We eat takeout, packaged and prepared meals.Why? Because it fits our notenoughtimeintheday lifestyles.__1__Well, I'm certainly not the first one to think it or say it, but we all need to slow down.‎ Consumer trends around the globe show that over the past three decades people are purchasing more prepared foods at groceries and eating out more than ever before.It's predicted that we'll spend more at restaurants in the coming years.__2__ However, we're getting less healthy.‎ While debates can be seen in different media over the food industry's contribution to our growing waistlines and our health problems, the bottom line is this：__3__We can choose to eat a fastfood lunch on the go.We can throw a frozen meal in the microwave and call it dinner.We can eat without thinking, in front of the tube, at our computers, and while driving a car.‎ ‎__4__Studies have shown meaningful links between family meals and kids' mental and physical wellbeing.Eating sensibly doesn't take much time or money, but it does require you to make a conscious decision to do so.Wrapped up in endless work, appointments and social activities, we often fail to enjoy a relaxing meal with our families.‎ While it can be a challenge to always put healthy eating first, just do your best.Remember that the food you eat has a more significant effect on your health, weight and wellbeing than almost any other activities you do.__5__ Every meal made at home — even just once or twice a week — is a step closer to a healthier body and a slower eating style.‎ A. Lunch is the biggest calorie intake when it comes to eating out.‎ B．Treat it with the importance that it deserves, but start small.‎ C．Our food matches our lives.‎ D．Purchase food locally and skip as many packaged items as you can.‎ E．What we eat, where we eat and how we eat are all under our control.‎ F．We're consuming an increasing number of calories.‎ G．We can devote an hour of the day to enjoying a meal with our families.‎ 语篇解读：本文是一篇议论文。因为生活节奏加快，许多人习惯于吃快餐。事实上，快餐并不健康，并且花费高；为此作者呼吁人们远离快餐，重视饮食习惯。‎ ‎1．选C　根据空前内容可知，随着人们生活节奏的加快，人们的饮食习惯也发生了改变。所以，C项“我们的食物适应我们的生活(方式)”符合语境。‎ ‎2．选F　根据空前的“It's predicted that we'll spend more at restaurants in the coming years.”可知，人们越来越多地在外面吃饭，摄入越来越多的卡路里，然而，人们在变得越来越不健康。故F项符合语境。‎ ‎3．选E　根据空后内容可知，我们可以选择在路上吃快餐，可以将冷冻食物放入微波炉当作正餐，我们可以在地铁前，在电脑旁，甚至在开车时想吃就吃。故E项符合语境。‎ ‎4．选G　根据空后的“Studies have shown meaningful links between family meals and kids' mental and physical wellbeing.”可知，与家人一块吃饭有很大的好处。所以，G项符合语境。‎ ‎5．选B　根据本段内容可知，饮食对人们的健康很重要。作者建议人们尽量在家吃饭。再结合空后内容可知，B项“把健康饮食放在第一位可从小事做起”符合语境。‎ Ⅲ.语法填空 ‎(2019·成都诊断)If you speak to a local about your stay in Chengdu, they'll probably ask if you've tried hot pot.Everyone __1__ (live) here seems to love it, and trying it should be a __2__ (fix) part of everyone's culinary tour of Sichuan.‎ Hot pot restaurants can __3__ (find) on pretty much every street in Chengdu, but the quality and taste can vary hugely.‎ When you do go for hot pot, you will often be asked to make a __4__ (choose) of broth in which you cook your raw ingredients (食材)．If you're __5__ (adventure) and up for a challenge, the traditional oily spicy broth might be just the thing you're after.But __6__ you haven't yet fully adapted to the local taste, you'd better choose a nonspicy broth, or __7__ (go) for a less spicy option.Bear __8__ mind that some broths like the tomato, mushroom or northern style will not be on offer at every restaurant.‎ Half spicy and half clear broth is __9__ (ready) available at most restaurants; these pots either come divided down the middle like a giant yin and yang, or with __10__ separate smaller pot of clear broth in the middle.If you can't bear too much chili and oil, but want to have a try, ask for yuanyangguo.‎ ‎1．living　考查非谓语动词。live和句子谓语seems之间没有连词，故空处应用非谓语动词，且动词live和句子主语Everyone之间构成逻辑上的主谓关系，故用现在分词作定语。‎ ‎2．fixed　考查非谓语动词。空处和句子谓语动词之间没有连词，故空处应填非谓语动词，又因动词fix和其逻辑主语之间为逻辑上的动宾关系，故用过去分词作定语。‎ ‎3．be found　考查动词语态。动词find和句子主语Hot pot restaurants之间是被动关系，故应用被动语态。‎ ‎4．choice　考查名词。根据空前的a和空后的of可知空处应填名词的单数形式。‎ ‎5．adventurous　考查形容词。根据空前的you're 可知，此处应用形容词adventurous作表语。‎ ‎6．if/when　考查连词。根据语境可知，空处可用if引导条件状语从句，表示对情况的假设；也可用when来引导时间状语从句，表示“当……时”。‎ ‎7．‎ go　考查动词。根据连词or可知，此处go和动词choose是并列关系，故用动词原形形式。had better do sth.“最好做某事”。‎ ‎8．in　考查介词。bear (sth.) in mind意为“记住某事”，为固定搭配，故用介词in。‎ ‎9．readily　考查副词。空处修饰形容词应用副词，故填readily，在句子中作状语。‎ ‎10．a　考查冠词。pot是可数名词，且此处表示泛指，又因separate的发音以辅音音素开头，故用不定冠词a。‎ Ⅳ.概要写作 阅读下面短文，根据其内容写一篇60词左右的内容概要。‎ Everyone looks forward to progress. Progress shows a person's ability to change the way he is living at the moment. Progress means a better way of doing things. However, all these remain true only when people want to accept technology and move forward by finding new and more efficient ways of doing things.‎ However, in the minds of many people, especially those who miss the “good old days”， progress goes with a price. Now communication becomes efficient. With the communication gadgets like mobile phones and iPads, people often do not take the effort to visit one another personally. A personal visit has the additional benefit of being in the person's presence for as long as the visit lasts.‎ With progress also comes mass production. Factories have improved efficiency. Unskillful tasks are left to machines and products are better made and produced with greater accuracy than any human hand could ever have done. However, with the improvements in efficiency also comes the loss of the personal touch when they are making these products. For example, many handcrafts (手工艺品) are now produced in a factory. Although this means that supply is better able to increase demand, mass production lowers the quality of the handcraft and it is difficult to find unique designs on each item.‎ Nevertheless, we must not analyze progress only from one point of view. In fact, progress has allowed tradition to keep up. It is only with progress and the invention of new technology that many old products can be brought back to their old state. New technology is required for old products to stay old.‎ It is people's attitude towards progress that causes the type of influence that technology has on society. Technology is flexible. There is no fixed way of making use of it. Everything depends on people's attitude.‎ 参考范文：‎ Though commonly expected, progress can benefit people only with their acceptance of modern technology and pursuit of efficiency. (要点1) However, to some people, advanced communication devices are to blame for the loss of personal visits despite their high efficiency. (要点2) The machinemade products also lack personal touch and uniqueness. (要点3) In fact, technological progress makes it possible for old products to survive. (要点4) Thus, it is people's attitude that decides the use of technology.(要点5)‎
