Food production With a 3D print

2、er,a cook can print plicated chocolate sculptures and beautiful pieces for decoration on a wedding cake.Not everybody can do thatit 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

3、cooks to plete other tasks.In another restaurant,all of the dishes and desserts it serves are 3D-printed,rather than farm to table.,Sustainability(可持續(xù)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 perce

4、nt to maintain current levels.Sustainability is being a necessity.3D food printing could probably contribute to the solution. Some experts believe printers could use hydrocolloids(水解膠體) from plentiful renewables like algae(藻類) and grass to replace the familiar ingredients(烹飪?cè)?.3D printing can reduc

7、llenges to overe.Currently,most ingredients must be changed to a paste(糊狀物) before a printer can use them,and the printing process is quite time-consuming,because ingredients interact with each other in very plex ways.On top of that,most of the 3D food printers now are restricted to dry ingredients,

8、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.,語(yǔ)篇解讀,語(yǔ)篇解讀本文是一篇科普說(shuō)明文,主要介紹了3D食物打印機(jī)的優(yōu)點(diǎn)和缺點(diǎn)。,46.What benefit does 3D printing bring to food production?

10、 can we learn about 3D food printing from Paragraph 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.,解析推理判斷題。根據(jù)第三段中的“Some experts believe printers could use hydrocolloids(水解膠

11、體) from plentiful renewables like algae(藻類) and grass to replace the familiar ingredients(烹飪?cè)?.”可知,3D打印機(jī)用的是可再生材料。故D項(xiàng)正確。,答案,解析,46,47,48,49,50,48.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 supermarke

12、ts D.can keep all the nutrition in raw materials,解析推理判斷題。根據(jù)第四段中的“Food printing could allow consumers to print food with customized nutritional content,like vitamins.”可知,3D打印機(jī)打印食物可以滿足個(gè)人的營(yíng)養(yǎng)需求。故答案為B。,答案,解析,46,47,48,49,50,49.What is the main factor that prevents 3D food printing from spreading widely?

14、新科技3D食物打印,故A項(xiàng)適合作文章標(biāo)題。,50.What could be the best title of the passage? A.3D Food Printing:Delicious New Technology B.A New Way to Improve 3D Food Printing C.The Challenges for 3D Food Production D.3D Food Printing:From Farm to Table,答案,解析,46,47,48,49,50,名師點(diǎn)津,一、題型解讀 記敘文、說(shuō)明文和議論文三種文體所涉及的不同話題的閱讀材料都會(huì)考查到標(biāo)題

15、歸納題。設(shè)問(wèn)形式常有: (1)Which of the following can be the best title for the passage? (2)What can be a suitable title for the passage/text? (3)What is the best title for this passage? (4)The most suitable title of this passage is . 一個(gè)好的標(biāo)題應(yīng)具備三大特點(diǎn):概括準(zhǔn)確而又簡(jiǎn)短;針對(duì)性標(biāo)題外延正好與文章內(nèi)容相符;醒目能引發(fā)讀者的閱讀欲望。,二、解題技巧 1.“高度概括”定標(biāo)題 (1)所

16、選文章標(biāo)題須能概括全文的中心內(nèi)容。標(biāo)題是文章的點(diǎn)睛之筆,是文章的靈魂和門面。為吸引讀者的注意,標(biāo)題往往比較醒目。 (2)一般文章的標(biāo)題可根據(jù)主題句來(lái)判斷,但在某些文章中,如記敘文,沒(méi)有明確的主題句,需要根據(jù)文中的事實(shí)細(xì)節(jié),查找文章的“主線”,歸納出文章的主題。,2.文章標(biāo)題三特點(diǎn) (1)形式一般為單詞、短語(yǔ)或句子,短語(yǔ)居多; (2)短小精悍,精確性強(qiáng); (3)涵蓋性強(qiáng),能覆蓋全文大意。 例如:【真題感悟】中第50題,要求概括標(biāo)題,文章主要介紹了3D打印技術(shù)在食物上的應(yīng)用取得了進(jìn)展,但目前仍面臨著許多方面的挑戰(zhàn)。所以用標(biāo)題“3D Food Printing:Delicious New Techn

17、ology”??忌龃祟}時(shí)一定要注意選項(xiàng)的內(nèi)容必須要能概括整個(gè)文章的內(nèi)容,不能以偏概全。如B、C、D選項(xiàng)的內(nèi)容在文章中都有所涉及,但不足以概括全文,所以需要考生正確概括全文的主旨大意。,隨堂限時(shí)練,A (2018天津十二區(qū)縣二模) Tears of relief and shouts of joy rang out at the San Jose Mine in northern Chile when 33 miners were lifted to freedom,one by one.The men,ranging from 19 to 63 years old,have been bur

30、g for ways to link the brain with puters.Brain-puter interface(界面)(BCI) technology could help people with disabilities send mands to machines. Recently,two researchers,Jose Milan and Michele Tavella from the Federal Polytechnic school in Lausanne,Switzerland,demonstrated(展示) a small robotic wheelcha

31、ir directed by a persons thoughts.,In the laboratory,Tavella operated the wheelchair just by thinking about moving his left or right hand.He could even talk as he watched the vehicle and guided it with his thoughts. “Our brain has billions of nerve ceils.These send signals through the spinal cord(脊髓

32、) to the muscles to give us the ability to move.But spinal cord injuries or other conditions can prevent these weak electrical signals from reaching the muscles,” Tavella says.“Our system allows disabled people to municate with external world and also to control devices.”,The researchers designed a

33、special cap for the user.This head cover picks up the signals from the scalp(頭皮) and sends them to a puter.The puter interprets the signals and mands the motorized wheelchair. The wheelchair also has two cameras that identify objects in its path.They help the puter react to mands from the brain. Pro

34、f.Milan,the team leader,says scientists keep improving the puter software that interprets brain signals and turns them into simple mands.“The practical possibilities that BCI technology offers to disabled people can be grouped in two categories:munication,and controlling devices.One example is this

35、wheelchair.”,He says his team has set two goals.One is testing with real patients,so as to prove that this is a technology they can benefit from.And the other is to guarantee that they can use the technology over long periods of time.,解析細(xì)節(jié)理解題。根據(jù)第一段可知,人類一直在尋找把人腦和電腦聯(lián)系在一起的方法,BCI可以幫助殘疾人向機(jī)器發(fā)布命令。由此可知,BCI是

36、一種可以連接人腦和電腦的技術(shù)。,6.BCI is technology that can . A.help to update puter systems B.link the human brain with puters C.help the disabled to recover D.control a persons thoughts,答案,解析,6,7,8,9,10,7.How did Tavella operate the wheelchair in the laboratory? A.By controlling his muscles. B.By talking to the

37、machine. C.By moving his hand. D.By using his mind.,解析細(xì)節(jié)理解題。根據(jù)第三段第一句“In the laboratory,Tavella operated the wheelchair just by thinking about moving his left or right hand.”可知,特維拉通過(guò)想著移動(dòng)左手或右手,就可以操作輪椅了。說(shuō)明他通過(guò)思維來(lái)控制輪椅。,答案,解析,6,7,8,9,10,8.Which of the following shows the path of the signals described in P

38、aragraph 5? A.scalpputercapwheelchair Bputercapscalpwheelchair C.scalpcapputerwheelchair D.capputerscalpwheelchair,答案,解析,6,7,8,9,10,解析細(xì)節(jié)理解題。根據(jù)第五段第前三句“The researchers designed a special cap for the user.This head cover picks up the signals from the scalp(頭皮) and sends them to a puter.The puter interp

39、rets the signals and mands the motorized wheelchair.”可知,首先頭皮接收人的思想信號(hào),接著特殊的帽子從頭皮上獲取信息,再傳到計(jì)算機(jī)上,最終計(jì)算機(jī)操作輪椅移動(dòng)。,6,7,8,9,10,9.The team will test with real patients to . A.make profits from them B.prove the technology useful to them C.make them live longer D.learn about their physical condition,解析細(xì)節(jié)理解題。根據(jù)最后

40、一段第二句“One is testing with real patients,so as to prove that this is a technology they can benefit from.”可知,他們把這個(gè)技術(shù)運(yùn)用于真正的病人身上是為了證明這個(gè)技術(shù)對(duì)病人有用。,答案,解析,6,7,8,9,10,解析標(biāo)題歸納題。文章第一段第二句“Brain-puter interface(界面)(BCI) technology could help people with disabilities send mands to machines.”指出BCI是一種可以連接人腦和電腦的技術(shù),未來(lái)它

41、能夠幫助殘疾人自由活動(dòng)。文章的其他部分則敘述了與之相關(guān)的研究信息。故C項(xiàng)為最佳標(biāo)題。,10.Which of the following would be the best title for the text?
