There’s a new frntier in 3D printing that’s beginning t cme int fcus:fd.Recent develpment has made pssible machines that print,ck,and serve fds n a mass scale.And the industry isn’t stpping there.
Fdprductin
With a 3D printer,a ck can print cmplicated chclate sculptures and beautiful pieces fr decratin n a wedding cake.Nt everybdy can d that—it takes years f experience,but a printer makes it easy.A restaurant in Spain uses a Fdini t “re-create frms and pieces” f fd that are “exactly the same,” freeing cks t cmplete ther tasks.In anther restaurant,all f the dishes and desserts it serves are 3D-printed,rather than farm t table.
Sustainability(可持續(xù)性)
The glbal ppulatin is expected t grw t 9.6 billin by 2050,and sme analysts estimate that fd prductin will need t be raised by 50 percent t maintain current levels.Sustainability is becming a necessity.3D fd printing culd prbably cntribute t the slutin.Sme experts believe printers culd use hydrcllids(水解膠體) frm plentiful renewables like algae(藻類) and grass t replace the familiar ingredients(烹飪原料).3D printing can reduce fuel use and emissins.Grcery stres f the future might stck “fd” that lasts years n end,freeing up shelf space and reducing transprtatin and strage requirements.
Nutritin
Future 3D fd printers culd make prcessed fd healthier.Hd Lipsn,a prfessr at Clumbia University,said,“Fd printing culd allw cnsumers t print fd with custmized nutritinal cntent,like vitamins.S instead f eating a piece f yesterday’s bread frm the supermarket,yu’d eat smething baked just fr yu n demand.”
Challenges
Despite recent advancements in 3D fd printing,the industry has many challenges t vercme.Currently,mst ingredients must be changed t a paste(糊狀物) befre a printer can use them,and the printing prcess is quite time-cnsuming,because ingredients interact with each ther in very cmplex ways.On tp f that,mst f the 3D fd printers nw are restricted t dry ingredients,because meat and milk prducts may easily g bad.Sme experts are skeptical abut 3D fd printers,believing they are better suited fr fast fd restaurants than hmes and high-end restaurants.

考點規(guī)范練37(選修8 Unit2)
Ⅰ.【解題導語】本文是一篇說明文,主要介紹一項新的3D食物打印技術。分別介紹食物打印的省時高效特點、所使用的原料的可持續(xù)性、提供顧客所需要的營養(yǎng)以及目前技術推廣面臨的挑戰(zhàn)等。
1.B 細節(jié)理解題。根據第二段第一、二句可知,用3D打印機,一名廚師可在婚禮蛋糕上打印出復雜的巧克力圖案和精美的裝飾,這并非每個人都能做到,這要廚師多年的經驗積累,但一臺打印機可以很容易就做到。由此可知,3D打印技術在食品制作方面節(jié)省了時間和精力。
2.D 推理判斷題。根據第三段第四句“Smeexpertsbelieveprinters...”可知,專家相信3D打印機可使用大量的藻類和草等可再生資源形成的水解膠體代替熟知的烹飪原料。
3.B 細節(jié)理解題。根據第四段中HdLipsn教授的話可知,食品打印能使得顧客打印出富含顧客個性化需求的營養(yǎng)成分,如維生素。因此,顧客不必吃昨天從超市買來的面包,而是隨需烤制。
4.C 細節(jié)理解題。根據最后一段第三句“Ontpfthat,...”可知,盡管3D食物打印技術進展迅猛,但所需的大多數打印材料必須是干燥的才能使用,這也就制約了食物打印技術的普及。
Ⅱ.【解題導語】本文是記敘文。作者遭受的一場車禍改變了她的生活。
1.B 根據本空前后句內容可知,作者遭受了一場車禍,車上還有她的兩個孩子,所以她當時應該感到“害怕(terrified)”。
2.D 根據本空后內容可知,“謝天謝地(Thankfully)”,作者的兩個孩子都安然無恙。
3.B 根據本句中的Despite可推測,盡管作者的左胳膊和脖子上有些擦傷,但是作者感覺“良好(fine)”,并無大恙。
4.C 根據上一句中的hspital可知,這里指“醫(yī)生(dctr)”說作者有腦震蕩。
5.A 根據本空下一句內容可知,作者走路搖搖晃晃,所以她感覺自己失去了內部“平衡(balance)”。
6.B 根據本句中的“Ihaddifficultyincmmunicating...”可知,作者跟人溝通有困難,她既記不住別人說的話,自己也“說(speak)”不清楚話。
7.A 根據本句中的sunglasses可知,作者戴墨鏡是為了保護“眼睛(eyes)”。
8.D 上段中的“ThefirstweekIfeltlike...”都是作者腦震蕩后表現出的“癥狀(symptms)”。
9.D 根據第一段中的“”可推測,作者只是有些擦傷,“身體上的(physical)”傷并不明顯。
10.B 根據本句中的“”可推測,人們以為作者痊愈了,尤其是她的外傷不明顯,因此“忘記(frget)”了她正遭受的痛苦。
11.C 根據本空后的butIhadn’t可推測,人們以為作者已經擺脫了車禍帶來的影響,“繼續(xù)向前(mven)”。
12.A 根據本空前的anxius及后面的stresseating可知,作者焦慮而且“緊張(stressful)”。
13.D 根據本空后的內容可知,作者“決定(decide)”自我治愈。
14.C 根據上段中的“Igained25punds...”可推測,這里指作者“減肥(lseweight)”。
15.B 根據本文開頭的“Lastyear,Ihadacaraccident.”可知,距離作者遭受那場“事故(accident)”已經將近一年了。
16.B 根據上句內容及本句中的可推測,盡管作者還受恐慌困擾,但是已經沒有那么“頻繁(frequently)”了。
17.A 根據本句開頭的Althugh可推測,盡管作者恢復得不快,但是作者眼中的呆滯和絕望“消失(gne)”了。
18.D 根據下段中的mysecndlife可知,這里指作者獲得了重新生活的“機會(chance)”。
19.D 本句后的內容就是作者要“怎樣(hw)”重新生活。
20.C 根據本句中的“I’llbecmemychildren’sstrngestbacker...”可知,作者要做孩子們最堅強的后盾并告訴他們:無論發(fā)生什么事情,“我”會“一直(always)”在。
Ⅲ.【解題導語】本文是一篇說明文,主要介紹了竹子在中國的廣泛應用及竹子所代表的含義。
1.musical 考查詞性轉換。根據詞法知識可知,名詞instruments前面應用music的形容詞形式來修飾,表示“樂器”。故填musical。
2.applicatin 考查詞性轉換。分析句子成分可知,該空在句中充當主語,應用apply的名詞形式applicatin,表示竹子在科學技術方面的運用。故填applicatin。
3.led 考查動詞時態(tài)。根據時間狀語In251BC可知,此處敘述的是過去發(fā)生的事情,應用一般過去時;且lead與其主語LiBing之間是主謂關系。故填led。
4.an 考查冠詞。為固定短語,意為“在……方面起……作用”;由于imprtant是以元音音素開頭的,故用不定冠詞an。
5.made 考查動詞語態(tài)。bemadef為固定短語,意為“由……制成”;此處表示世界上最古老的水管也是由竹子制成的,符合語境。故填made。
6.successfully 考查詞性轉換。此處應用success的副詞形式修飾動詞sank。故填successfully。
7.until 考查固定結構。根據語境可知,這個技術直到19世紀才傳到歐洲。意為“直到……才”,符合語境。故填until。
8.that 考查強調句型。分析句子結構可知,本句為“Itis/was+被強調部分+that...”的強調句結構,此處應用that,強調方式狀語byusingthetechnlgy。故填that。
9.ne 考查代詞。根據常識可知,在中國文化中,竹子是植物中的“四君子”之一。nef意為“……之一”,符合語境。故填ne。
10.facing 考查省略。分析句子結構可知,在when引導的時間狀語從句中,face與其邏輯主語peple之間為主謂關系,故此處應用face的動詞-ing形式,從句中省略了主語peple和be動詞are。故填facing。
Ⅳ.Dear Tm,
It is nice t receive yur email.Nw I’d like t tellingtell yu smething abut the Palace Museum.The Palace Museum,als callcalled the Frbidden City,began t be built in 1406.It tk mre than a millin wrkerwrkers 14 years t build it and the Palace Museum haswas finished in 1420.Yu may be surprisingsurprised that the palaces in the Frbidden City have 9,999 rms altgether and as yu knw it in China,“nine” is regarded as the lucky number.As ∧the largest museum in the wrld,the Palace Museum heldhlds cultural treasures frm the past 5,000 years f Chinese histry.Nw,every Tuesday,the Palace Museum is pen t Chinese students fr free butand I hpe yu have a chance t cme t China and take a lk frat it with yur wn eyes.
