Italian bioengineer Giuppe Scionti from Spanish startup Novameat has invented the “world's first”3D—printed meat—free steak made from vegetable proteins，which mimics(模仿) the texture of beef。
Vegan ingredients such as rice，peas and aweed，which provide the amino acids nee
ded for a healthy diet，are turned into a food paste that is 3D—printed to form a raw and steak-like substance。mltr
Despite an abundance of meat—free products already on the market that taste similar to animal meats，Scionti found that the are limited to imitation burgers,or meatballs。In an effort to reduce the impact of animal agriculture and to improve people’s nutrition，the Milane rearcher t out to create a plant-bad alternative to “fleshy” meat products。
By combining tissue engineering and bio-printing with modern cooking methods，he created a vegan product that boasts the same consistency,appearance and nutritional properties as animal meat products.3D printing allowed the scientist to generate complex and micro-structured three-dimensional forms that are impossible to achieve using other techniques。
Syringes（注射器) containing the light—colored food paste were placed in a 3D printer，which followed a pre-t code designed by Scionti using computer-aided design（CAD) s
oftware,to print out the mixture in the shape of a small steak that can then be cooked。It did not include any colourant(着色剂）。It was a light brown color，similar to ordinary cooked meat。
While there are some companies working on the creation of artificial meat from animal cells cultured in the labs,sometimes known as “clean meat"，this kind of meat takes a long time to make and is expensive。Scionti’s method allows him to print a 100-gram piece of steak in around 30 minutes。
In addition to creating an ethical meat alternative，Scionti designed the meat-free steak to help in reducing greenhou gas emissions from livestock，which account for 14.5 percent of the current total man—made greenhou gas emissions.
“The latest reports from the Food and Agriculture Organization of the United Nations(FAO) show that the current large-scale livestock breeding is no longer sustainable globally，"he explained.“If we continue with the current system，in the future there will be little chance of having the resources to distribute food to everyone，”he conti
nued。
“It is for the reasons that finding another way of producing healthy and economical food that contains all the fundamental nutrients will help us to better manage our planet’s food resources。”
1.Scionti owed his success to 福建省二级建造师报名.
A。the adequate supply of meat products
B。the application of advanced technology
C。the great demand for meat-free products
D。the general support from all walks of life
答案 B
解析 推理判断题。根据第四段内容可知,Scionti认为自己之所以能够造出“素牛排”，是因为有了3D打印技术的支持。故选B。
氧化剂2。Compared with “clean meat”,what is the advantage of Scionti’s steak？
A。Including little colourant.
B.Providing more nutrition.
C。Consuming much less time。
D。Causing no harm to humans。
答案 C
解析 细节理解题.根据第六段中“.。。sometimes known as ‘clean meat'，this kind of meat takes a long time to make and is expensive。Scionti’s method allows him to print a 100-gram piece of steak in around 30 minutes.”可知，与利用动物细胞所造的“人造肉”相比,Scionti的“素牛排"耗时更少.故选C。
3.What is one of Scionti’s purpos in designing the meat—free steak？
A.To promote the 3D printing technology.
B.To avoid global food crisis in the future。
C。To provide affordable food for poor areas。
D。To meet consumers' requirements for meat.
答案 B
解析 推理判断题。根据倒数第二段最后一句和最后一段可知，Scionti希望通过这种“造肉”的方式来避免未来世界可能会出现的食物危机。故选B。
