10：二、阅读理解：阅读下面的短文，根据文章内容进行判断，正确写“T”错误写“F”。 教材课文原文THE COMPANY LEADING THE FUTURE OF FARMING Here’s a crazy idea: Combinebioprinting and tissue engineering to “print” animal products andtackle some of the planet’s biggest problems. Animal farming, after all,accounts for about half of all human-caused greenhouse gases, taking place onone-third of the available, non-frozen land on Earth. All to feed people’sappetites for 300 million tons of meat a year. Modern Meadow is aMissouri-based startup that engineers tissues to create lab-grown edible meat,in a process that eliminates many of the negative environment effectsassociated with traditional livestock practices. The company claims that bycarefully layering mixtures of cells of different types in a specificstructure, in-vitro meat production becomes feasible. It’s set a short-termgoal of printing a sliver of meat around two centimeters by one centimeter, andless than half a millimeter thick, which is edible. The company explains in asubmission to the United States Department of Agriculture: “The technology hasseveral advantages in comparison to earlier attempts to engineer meat in vitro.The bio-ink particles can be reproducibly prepared with mixtures of cells ofdifferent type. Printing ensures consistent shape, while post-printingstructure formation and maturatio国开答案请进：opzy.net或请联系微信：1095258436n in the bioreactor facilitates conditioning.”However, it admits that the road ahead is strewn with difficulties. “Theconsumer acceptance of such products may not be without challenges. We expectit will first appeal to culinary early-adopter consumers and the segment of thevegetarian community that rejects meat for ethical reasons. With reduction inprice, it can reach the masses with religious restrictions on meat consumption(people restricted to Hindu, Kosher, Halal diets) and finally populations withlimited access to safe meat production.” Whatever the final outcome, lab-grownedible meat is no longer in the realm of science fiction. It is coming. 1. Animal farming is responsible for theoccurrence of greenhouse gases.{T; F} 2. Modern Meadow is a newly-startedbusiness which aims to make profits by producing lab-grown edible meat.{T; F}3. The method Modern Meadow adopted to produce in-virto meat is by layeringmixtures of cells of different types in a specific structure.{T; F} 4. There isno meat engineered outside living bodies before.{T; F} 5. This lab-grown meathas already widely received by the masses.{T; F}
14：二、阅读理解：阅读下面的短文，根据文章内容从A、B、C三个选项中选出一个最佳选项。 （课外选材） According to experts, theadvantage of modified food is that it helps in preventing the occurrence ofallergies and also has a long shelf life. However, a major portion of thepopulation is against the consumption of genetically modified food and isconcerned about its disadvantages. If you are also confused about theconsumption of genetically modified food, read through the pros and cons givenbelow and decide for yourself. ADVANTAGES OF GENETICALLY MODIFIED FOODS ●One ofthe most prominent advantages of genetically modified food is that it helps incontrolling the occurrence of certain diseases. Certain foods cause allergy topeople. Their genetic modification alters the DNA system of these foods,thereby making them non-allergic. ●Another major advantage of such type offoods is that they grow faster than their traditionally grown counterparts. Asa result, there is greater productivity and more food. ●A person need notbother about any additional costs, such as buying chemicals and pesticides,when it comes to genetically engineered food. The food is naturallypest-resistant. ●Farming these foods can be a great way to fight world hunger.Since these crops grow faster or more effectively, increased production wouldhelp countries wherein crops may not normally prosper because of less thandesirable environmental conditions. ●The increased shelf life of these foodproducts helps in reducing the quantity of rotten food. DISADVANTAGES OFGENETICALLY MODIFIED FOODS ●The biggest disadvantage of genetically modifiedfood is that they have harmful effects on the human body. The consumption ofthese genetically engineered foods can lead to development of diseases that areimmune to antibiotics. ●Chances of developing cancer are high in people whoregularly consume engineered food. ●Since it is an unnatural way of producingfoods, there is an increased health hazard such as allergens, transfer ofantibiotic resistance markers and unknown effects. ●Since the production ofengineered food involves infusing animal genes in the crops and tampering withnature, it might not be good for consumption in the long run. 1. How does genetically modified food controlthe occurrence of certain diseases{A; B; C} A. By cross-pollinating. B. Byconventional crossbreeding. C. By altering the DNA system of these foods. 2. Dofarmers need to buy any chemicals and pesticides if they plant geneticallymodified food{A; B; C} A. Yes, they need to. Because the food is not resist topests. B. No, they don’t need to. Because the food is naturally pest-resistant.C. No, they don’t need to. Because the chemicals and pesticides are provided bythe government. 3. Which statement is not the advantage of genetically modifiedfood{A; B; C} A. It may have harmful effects on human body. B. Geneticallymodified food grows faster than their traditionally grown counterparts. C.Farming genetically modified food can help fight world hunger. 4. What wouldhappen to a person if he regularly consume genetically modified food{A; B; C}A. He would get cold. B. He would lose some weight. C. He would have cancer. 5.Which title is the best for this passage{A; B; C} A. Can genetically modifiedfoods combat world hunger B. Genetically modified mood: our answer is no C.Genetically modified foods: pros and cons
