2、ult.Plants have tens of thousands of genes.The geneticallymodified product(GMP)wont be dramatically different from its natural one.It may have a few features that thenatural version doesnt have but otherwise will remain identical.Some people worry that genetic modification,which introduces genes fro
3、m one species into an entirelydifferent species,could create new allergens(过敏原).In fact,it may turn out that the opposite is true.Dependingon the food,scientists might be able to remove or prevent the proteins that act as allergens for some people.Thisisnt true for every food,but genetic markers sci
4、entists use could lead to developing bacteria with a built-inresistance to antibiotics(抗生素).Scientists use antibiotic gene markers to link genes for the desired features.Also,by exposing modified planfs cells to antibiotics,a scientist can confirm whether or not the genetic modificationwas successfu
5、l.But what if that resistance could be passed on the bacteria?Its possible that bacteria in the soil around a plantwith antibiotic resistance could pick up the DNA.The bacteria could,in theory,pass this feature to other types ofbacteria harmful to humans.So far,however,scientists have been unable to
6、 transfer antibiotic resistance genes fromplants to bacteria.In the United States,farmers dont have to label genetically modified foods or products.Both theEnvironmental Protection Agency and the Food and Drug Administration have very strict regulations that productsmust pass before they can go to m
7、arket.Ifs possible that the foods that come from biotechnology are not only safe to eat,but theyre actually saferthan their natural counterparts.While the controversy around genetically modified food is far from resolved,itappears that you shouldnt worry if the ear of corn youre about to enjoy got i
8、ts start in a laboratory.1.How could scientists deal with a plant in biotechnology?A.By changing some cells.B.By adding some foreign genes.C.By producing some natural proteins.D.By removing some of its branches.2.The exposure of modified plants cells to antibiotics is aimed to.A.promote their resist
9、ance.B.get their unexpected features.C.see the effect of the modification.D.improve the ability against bacteria.3.What can be concluded from the text?A.It takes time fbr customers to accept bioengineered food.B.The laws in America are far from strict in regulating the GMRC.American farmers only car
10、e about improving their food produce.D.Scientists have developed certain food beneficial to human health.4.What attitude does the author hold to the GMP?A.Positive.B.Negative.C.Ambiguous.D.Indifferent.【答案】BCAA【分析】这是一篇说明文。主要讲述了尽管科学家们在生物技术领域修改植物基因进行了很多年,但他们通常专注于一些特定的基因以获得特定的结果。尽管围绕转基因食品的争议尚未解决,但也没有必要有
11、如此大的担心。1.细节理解题。由第一段“While scientists have been modifying(修改)plant genes for years in biotechnology,they usually focus on a few specific genes in order to get a particular result.(尽管科学家们在生物技术领域修改植物基因进行了很多年,但他们通常专注于一些特定的基因以获得特定的结果。)以及第二段“Some peopleworry that genetic modification,which introduces gene
12、s from one species into an entirely different species,couldcreate new allergens(过敏原)(有人担心,将一个物种的基因导入一个完全不同的物种的基因改造会产生新的过敏原。)可知,在生物领域,科学家通过添加外来的基因来修改植物基因。故选B 项。2.细节理解题。由第二段“Also,by exposing modified plants cells to antibiotics,a scientist can confirm whetheror not the genetic modification was success
13、ful.(另外,通过将修改过的植物细胞暴露于抗生素中,科学家可以确认基因修改是否成功。)可知,把修改过的植物基因放入抗生素中的目的是为看基因修改的是否成功,即修改的效果。故选C 项。3.推理判断题。由第二段“Some people worry that genetic modification,which introduces genes from one speciesinto an entirely different species,could create new allergens(过敏原)(有人担心,将一个物种的基因导入一个完全不同的物种的基因改造会产生新的过敏原。)可知,人们对于
14、转基因食品有着担心,所以推知对于生物改造过的食品会需要时间来接受。故选A 项。4.推 理判断题。由最后一段 Its possible that the foods that come from biotechnology are not only safe to eat,buttheyre actually safer than their natural counterparts.While the controversy around genetically modified food is farfrom resolved,it appears that you shouldnt wor
15、ry if the ear of com youre about to enjoy got its start in alaboratory.(来自生物技术的食品不仅可以安全食用,而且实际上比天然食品更安全。尽管围绕转基因食品的争议尚未解决,但您似乎不必担心即将要享用的玉米穗是否来自实验室)可知,作者认为来自生物技术的产品比天然产品更安全,对于人们吃的食品提出不必担心。由此推知,作者对GMP持积极的态度。故选A 项。BLuke Grenfell-Shaw has developed a rare form of cancer.It started as a pain in his should

24、 hard and got rewards in terms ofeducation,jobs,things like that.That was all taken away.(我的生活曾经是舒适而传统的。我努力工作,在教育、工作等方面得到了回报。这一切都被夺走了。)可知,Luke对自己的病情的严重非常震惊,感觉到自己原来舒适的生活都被夺走了,可以推知“That day,I felt like my life was disintegrated.(那一天,我感觉自己的生活disintegraled.)中划线单词的意思应该是“极其糟糕的,不 幸 的 选 项 A“破碎的”与之最为接近,故选 A
25、项。7.推理判断题。根据第二段中“On the day of his diagnosis(诊断),Luke had one clear thought in his mind that hewanted to cycle around the world.It was something he had always hoped to do,but the cancer news made himrealize that he couldnt put it ofT.(在他被确诊的那天,Luke在他的脑海中有一个清晰的想法,他想要环游世界。这是他一直希望做的事情,但癌症的消息让他意识到他不能推迟。
