Yours, Li_Hua 理清文体结构之(十一) 说明文之事物类——抓说明对象,根据事物特点巧解题 事物类说明文一般在首段给出说明对象,然后从几个方面对事物进行客观说明。因此,该类文章的行文结构一般较为简单,阅读时不要拘泥于细枝末节,浏览完全文后,带着题干中的关键词,再次跳读原文查找答案出处,认真比对,从而得出正确答案。 [高考典例] 2018·天津卷·C篇 [抓事物特点] [高考典例] 2018·天津卷·C篇 [读文解题技法] 点明 说明 对象 特点1 特点2 关键词 特点3 特点4 [1]There’s a new frontier in 3D printing that’s beginning to come into focus: food. Recent development has made possible machines that print, cook, and serve foods on a mass scale. And the industry isn’t stopping there. Food production [2]With a 3D printer, a cook can print complicated chocolate sculptures and beautiful pieces for decoration on a wedding cake. Not everybody can do that — it takes years of experience, but a printer makes it easy. A restaurant in Spain uses a Foodini to “recreate forms and pieces” of food that are “exactly the same,” freeing cooks to complete other tasks. In another restaurant, all of the dishes and desserts it serves are 3Dprinted, rather than farm to table. Sustainability (可持续性) [3]The global population is expected to grow to 9.6 billion by 2050, and some analysts estimate that food production will need to be raised by 50 percent to maintain current levels. Sustainability is becoming a necessity. 3D food printing could probably 1.读首段抓说明对象 本文在首段首句介绍了3D打印技术的新领域——打印食物。 2.览标题,看行文结构 本文从Food production, Sustainability, Nutrition, Challenges 四个方面介绍了3D打印食物的优缺点。 3.标题眼,找特点,比对定答案 contribute to the solution. Some experts believe printers could use hydrocolloids (水解胶体) from plentiful renewables like algae (藻类) and grass to replace the familiar ingredients (烹饪原料).3D printing can reduce fuel use and emissions. Grocery stores of the future might stock “food” that lasts years on end, freeing up shelf space and reducing transportation and storage requirements. Nutrition [4]Future 3D food printers could make processed food healthier. Hod Lipson, a professor at Columbia University, said, “Food printing could allow consumers to print food with customized nutritional content, like vitamins. So instead of eating a piece of yesterday’s bread from the supermarket, you’d eat something baked just for you on demand.” Challenges [5]Despite recent advancements in 3D food printing, the industry has many challenges to overcome. Currently, most ingredients must be changed to a paste (糊状物) before a printer can use them, and the printing process is quite timeconsuming, because ingredients 标出题干中的关键词,再次跳读原文,查找事物特点,认真比对,得出答案。 interact with each other in very complex ways. On top of that, most of the 3D food printers now are restricted to dry ingredients, because meat and milk products may easily go bad. Some experts are skeptical about 3D food printers, believing they are better suited for fast food restaurants than homes and highend restaurants. [由题眼找特点,比对定答案] 46.What benefit does 3D printing bring to ? A.It helps cooks to create new dishes. B.It saves time and effort in cooking. C.It improves the cooking conditions. D.It contributes to restaurant decorations. 47.What can we learn about 3D food printing from ? A.It solves food shortages easily. B.It quickens the transportation of food. C.It needs no space for the storage of food. D.It uses renewable materials as sources of food. 48.According to , 3Dprinted food________. A.is more available to consumers B.can meet individual nutritional needs C.is more tasty than food in supermarkets D.can keep all the nutrition in raw materials [答案] 46.B 47.D 48.B 46.根据题干中的关键词语food production可定位到“特点1”,认真比对,可得出答案。 47.第三段的标题(特点2)“可持续性”暗含了3D打印机的材料应是可再生的,再据关键词“renewables”便可确定答案。 48.根据第四段中的“特点3”可推知答案。查看更多
