生物学家也在发动一场生物技术革命,他们借鉴“人类基因组规划”,也在绘制“动植物基因图”。由于有了新的基因标志,靠考察胚胎和幼苗的染色体,就可以知道一种生物具有什么基因。育种专家将能很快找到抗疾病、抗虫害和提高产量的理想基因,很容易发现哪些物种相互交配可以产生最理想的新物种。人们将不再经三四代,只要一代就可育出新种,而且不产生非自然的遗传工程生物。农作物和牲畜的品种改良速度将大大加快。 这段话中,“不产生非自然的遗传工程生物”的意思是( )。

A.人们利用基因培育出的生物新品种,与生物自然交配产生出的品种品质完全一样

B.人们利用基因培育出新的生物品种,不再利用遗传基因而生产新的劣质的生物品种

C.非自然的遗传工程生物不具有自然界生物的纯洁性,有了基因工程,它就不再出现了

D.非自然的遗传工程生物会造成生物生长规律的紊乱,改变生物的性质,因此停止再生产

Within a few years, Kurzweil (13) the price range will be low enough for every school and library to (14) one. Michael Hingson, Director of the National Federation for the Blind, hopes that (15) will be able to buy home (16) of Cyclops for the price of a good television set.

Mr. Hingson’s organization purchased five machines and is now testing them in Maryland, Colorado, Iowa, California, and New York. Blind people have been (17) in those tests, making lots of (18) suggestions to the engineers who helped to produce Cyclops.

"This is the first time that blind people have ever done individual studies (19) a product was put on the market," Hingson said. "Most manufacturers believed that having the blind help the blind was like telling disabled people to teach other disabled people. In that (20) , the manufacturers have been the blind ones.
