分析 本文主要介紹了基因工程技術(shù).基因工程可以將所需的生物轉(zhuǎn)化為不同物種的生物,它為農(nóng)業(yè)做出了巨大的貢獻(xiàn).而轉(zhuǎn)基因食品是不必要的,因?yàn)樗粫?huì)幫助解決世界上的饑餓問題,并且還可能存在一些隱患.
解答 67.C推理判斷題.根據(jù)第一段Unlike traditional breeding (繁殖),where a desired quality would be bred within the same species,genetic engineering can insert desired ones into organisms of different species.可知傳統(tǒng)育種不同于基因育種,傳統(tǒng)育種發(fā)生在同一物種之間.故選C.
68.A細(xì)節(jié)推理題.根據(jù)第四段due to the lack of labeling if allergies develop,it will be extremely difficult to find the origin of them.可知由于缺乏信息的記錄,如果過敏原發(fā)展,將很難找到他們的起源.由此推知,"The lack of labeling"暗示了關(guān)于基因的來(lái)源對(duì)于客戶來(lái)說(shuō)是不可獲取的.故選A.
69.A細(xì)節(jié)理解題.根據(jù)第五段GE food is unnecessary,and fails to address the root of hunger.可知轉(zhuǎn)基因食品是不必要的,因?yàn)樗粫?huì)幫助解決世界上的饑餓問題.故選A.
70.B細(xì)節(jié)理解題.根據(jù)最后一段可知作者不贊同轉(zhuǎn)基因技術(shù).故選B.
點(diǎn)評(píng) 本文考察學(xué)生的理解推斷能力以及細(xì)心程度,只要抓住文章的關(guān)鍵詞,采用尋讀的方法查找細(xì)節(jié),就能找到正確答案.
