The dictionary was actually nothing more than a list of about 3,000 difficult words, each followed by a one word definition. The author, Robert Cadre, made no attempt to include everyday words in his dictionary. During the 1600s more dictionaries were published. Each followed Cadre's lead and presented a few thou sand hard words. Around 1700 one dictionary maker, John Kersey, did define easy words as well as hard ones. But until the 1750s all dictionaries were rather crude and not very valuable. A man named Dr. Samuel Johnson changed all this. In 1755, Dr. Johnson produced the first modern dictionary. He included in his dictionary all. important words, and he gave good meanings. By the end of the 1700s most dictionary makers had followed Johnson's lead. Dictionaries were getting better and better. The 1800s saw the greatest improvement in the quality of dictionaries. In England scholars planned and prepared the Oxford English Dictionary. One of the most interesting features of the Oxford Dictionary is its word histories. It traces the history of each word from its earliest recorded use up to the time of the printing of the dictionary. (27)

【单选题】科学研究发现人体的P53基因是一种遏制细胞癌化的基因,几乎所有的癌细胞中都有P53基因异常的现象。现在通过动物病毒将正常的P53基因转入癌细胞中,发现能引起癌细胞产生“自杀现象”,从而为癌症的治疗又提供了一个解决途径。请推测下列有关说法中,不正确的是 [     ]
A.
癌细胞的P53基因发生了基因突变
B.
转入P53基因后,癌细胞产生的“自杀现象”属于细胞凋亡
C.
正常的P53基因相对于异常基因是显性基因
D.
转入P53基因后,癌细胞发生了染色体数目变异

E.
医生没有向病人说明手术后可能出现的后遗症,病人思想准备不够
【多选题】关于癌症基因疗法说法正确的是【 】
A.
基因疗法是指用基因工程技术将修补好的或经改造的基因注入人体,替代不正常基因进行工作而达到治疗目的
B.
遗传病都是由于遗传基因结构和功能出现问题而引起,科学家们设想通过矫正缺陷基因或替换不正常基因的方法,从根本上治愈遗传病
C.
癌基因集中在染色体遗传学较弱的片断附近。这个区域对化学致癌物、物理辐射特别敏感,基因容易发生改变
D.
染色体从某个癌基因处发生断裂,则正常的基因控制系统就会被破坏,从而导致癌变
