" 七、阅读理解: 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 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 " re-create 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 3D-printed, rather than farm to table. Sustainability(可持续性) 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 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 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 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 time-consuming, because ingredients 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 high-end restaurants. 1. What benefit does 3D printing bring to food production? 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. 2. What can we learn about 3D food printing from Paragraphs 3? 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. 3. According to Paragraph 4, 3D-printed 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 4. What is the main factor that prevents 3D food printing from spreading widely? A. The printing process is complicated. B. 3D food printers are too expensive. C. Food materials have to be dry. D. Some experts doubt 3D food printing 一、选择填空 1. 答案：C 解析：“can never...too...” 是固定表达，意为 “再…… 也不为过”，这里表示你无论怎样赞扬这个年轻人都不为过，所以选 C。 2. 答案：B 解析：“in public” 是固定短语，意为 “在公共场合”，中间不加冠词；“in a lower voice” 表示 “用更低的声音”，这里是泛指，用不定冠词 a，所以选 B。 3. 答案：D 解析：if 引导的条件状语从句遵循 “主将从现” 原则，即主句用一般将来时，从句用一般现在时。“it” 指代 “the car”，和 “check” 之间是被动关系，所以用一般现在时的被动语态 “isn't checked”，选 D。 4. 答案：B 解析：“while” 引导时间状语从句时，若从句主语和主句主语一致，且从句中有 be 动词，可以省略从句的主语和 be 动词，“while solving the problem” 相当于 “while you are solving the problem”；“none” 强调数量上 “一个也没有”，“nothing” 指 “没有东西”，这里问面对多少困难，用 “none”，所以选 B。 5. 答案：A 解析：“keep...in place” 表示 “使…… 固定在适当的位置”，是固定短语，所以选 A。 6. 答案：C 解析：“patient” 和 “operate on” 之间是被动关系，所以用被动语态 “be operated on”；“when” 引导的时间状语从句遵循 “主将从现” 原则，“the doctor” 是第三人称单数，“arrive” 是不及物动词，这里用 “arrives”，所以选 C。 7. 答案：A 解析：“cost” 表示 “花费”，主语是物，通常用 “cost little” 表示 “花费很少”；“cheap” 是形容词，不能修饰动词 “cost”；“a little” 表示 “一点儿”；“few” 修饰可数名词复数，所以选 A。 8. 答案：A 解析：“run out” 表示 “用完，耗尽”，是不及物动词短语，没有被动语态；“use up” 表示 “用完，耗尽”，是及物动词短语，“天然气储量” 应该是 “被用完”，要用被动语态 “be used up”；“clean up” 表示 “打扫干净”，不符合语境，所以选 A。 9. 答案：B 解析：“news” 是不可数名词，用 “What + 形容词 + 不可数名词 + 其他成分！” 的感叹句结构；“so many” 表示 “如此多的”，修饰可数名词复数，所以选 B。 10. 答案：D 解析：A 选项 “It depends.” 表示 “看情况而定”；B 选项 “I can't agree more” 表示 “我完全同意”；C 选项 “It's up to you.” 表示 “由你决定”；D 选项 “No, thanks” 表示 “不，谢谢”，根据 “That's the last thing in the world I ever want to do.” 可知拒绝了邀请，所以选 D。 11. 答案：B 解析：“She” 和 “expect” 之间是被动关系，即 “她不被期望”，用被动语态；根据 “before the race started” 可知用一般过去时，所以是 “wasn't expected”，选 B。 12. 答案：C 解析：“another” 表示 “另一个，再一个”；“have sth. done” 表示 “让某事被做”，“teaching building” 和 “build” 之间是被动关系，所以用 “built”，选 C。 13. 答案：D 解析：“can't” 表示 “不可能”，“mustn't” 表示 “禁止”，“may” 表示 “也许”，根据 “after such a long time” 可知在这么长时间后不可能有幸存者，用 “can't”；“alive” 表示 “活着的”，“dying” 表示 “快要死的”，“dead” 表示 “死的”，这里说两个年轻人被发现还活着，用 “alive”，所以选 D。 14. 答案：C 解析：“Each of...” 作主语时，谓语动词用单数形式；“picture” 和 “take” 之间是被动关系，要用被动语态，根据 “many years ago” 可知用一般过去时，所以是 “was taken”，选 C。 15. 答案：C 解析：“不知道” 这个动作发生在对方提醒之前，是过去的动作，用一般过去时 “didn't know”；“站得离交通这么近” 是在对方提醒时正在进行的动作，用过去进行时 “was standing”，所以选 C。 16. 答案：B 解析：“until” 引导的时间状语从句遵循 “主将从现” 原则，“it” 指代 “the new building”，和 “complete” 之间是被动关系，所以用一般现在时的被动语态 “is completed”，选 B。 17. 答案：B 解析：“sell out” 表示 “卖完，售罄”，强调结果；“sell well” 表示 “畅销”，强调状态。第一空表示 CD 卖完了，用 “sold out”；第二空表示 CD 畅销，用 “sell well”，所以选 B。 18. 答案：D 解析：A 选项 “you are right” 表示 “你是对的”；B 选项 “best wishes” 表示 “最美好的祝愿”；C 选项 “also thought that” 表示 “也那样认为”；D 选项 “better luck next time” 表示 “下次好运”，对方没得到工作，应该用 “better luck next time” 安慰，所以选 D。 19. 答案：A 解析：“missed the boat” 表示 “错过机会”，A 选项 “lose a chance” 符合；B 选项 “lose one's way” 表示 “迷路”；C 选项 “lose heart” 表示 “灰心”；D 选项 “lose money” 表示 “赔钱”，所以选 A。 20. 答案：B 解析：A 选项 “a good miss is as good as a mile” 表示 “差一点和差很多都是一样的，未中目标，功亏一篑”；B 选项 “it never rains but it pours” 表示 “祸不单行”；C 选项 “the early bird catches the worm” 表示 “早起的鸟儿有虫吃”；D 选项 “every dog has its day” 表示 “人人都有得意日”。这里说 Jim 车抛锚后又被后面的车撞了，是祸不单行，所以选 B。 二、根据句意、中英提示完成下列句子 1. 答案：against 解析：“beat against” 表示 “拍打，击打”，这里指雨重重地打在窗户上，所以填 against。 2. 答案：recycling 解析：“for” 是介词，后面接动词的 -ing 形式，“回收利用” 是 “recycle”，所以填 recycling。 3. 答案：wisely 解析：这里需要一个副词修饰动词 “spend”，“明智” 的形容词是 “wise”，副词是 “wisely”，所以填 wisely。 4. 答案：divide 解析：“put things into different groups” 意思是 “把东西分成不同的组”，即 “divide”，“You ’d better” 后面接动词原形，所以填 divide。 5. 答案：serious 解析：根据 “I am not joking now.” 可知 “我是认真的”，“认真的” 是 “serious”，所以填 serious。 6. 答案：produce 解析：“cause a result” 意思是 “产生一个结果”，即 “produce”，“can” 后面接动词原形，所以填 produce。 三、请根据句意从方框中选出合适的词，并用其适当形式填空 1. 答案：fifth 解析：“It’s the + 序数词 + time that...” 表示 “这是第…… 次……”，“five” 的序数词是 “fifth”，所以填 fifth。 2. 答案：differences 解析：“notice the differences between...” 表示 “注意到…… 之间的差异”，“different” 的名词是 “difference”，这里用复数形式，所以填 differences。 3. 答案：saddest 解析：根据 “I have ever heard” 可知用最高级，“sad” 的最高级是 “saddest”，所以填 saddest。 4. 答案：successfully 解析：这里需要一个副词修饰动词 “held”，“success” 的副词是 “successfully”，所以填 successfully。 5. 答案：men's 解析：这里表示 “男人的购物选择”，“man” 的复数是 “men”，名词所有格是 “men's”，所以填 men's。 四、请根据句意从方框中选出合适的动词，并用其适当形式填空 1. 答案：will be held 解析：“The sports meeting” 和 “hold” 之间是被动关系，要用被动语态；“next month” 表示将来的时间，用一般将来时，所以是 “will be held”。 2. 答案：was raining 解析：根据 “it was difficult to see the road clearly” 可知在事故发生时雨正在下，用过去进行时，“it” 是第三人称单数，所以是 “was raining”。 3. 答案：have known 解析：“父母看起来悲伤” 说明他们已经知道发生在 Amy 身上的事情了，用现在完成时，“they” 是复数，所以是 “have known”。 4. 答案：comes 解析：“Here comes...” 是倒装结构，表示 “…… 来了”，“Daniel” 是第三人称单数，所以用 comes。 5. 答案：is singing 解析：根据 “Listen!” 可知用现在进行时，“The whole class” 表示一个整体，看作单数，所以是 “is singing”。 6. 答案：thought 解析：“我原以为字典放在桌子上了”，“以为” 这个动作发生在过去，用一般过去时，所以是 “thought”。 五、句型转换 1. 答案：didn't read 解析：原句是一般过去时，变否定句要借助助动词 didn't，动词还原为原形，所以是 “didn't read”。 2. 答案：are;
