6、were nonsmokers.Scientists compared their genes and found that more than 7, 000 genes of smokers had changeda number that is onethird of known human genes.According to NBC News, both heart disease and cancer are caused by genetic changes.Some people may have had the changes when they were born, but
7、most people get them in their daytoday lives while doing things like smoking.When you stop smoking, a lot of these genes will return to normal within five years.This means your body is trying to heal (治愈) itself of the harmful effects of smoking.But the changes in some of the genes stay for longer.T

11、search.BThe findings have prevented more people from starting smoking.CThe findings offer evidence that a damaged gene can heal itself.DThe findings help to find cures for genetic damage caused by smoking.答案与解析这是一篇说明文。研究发现即使已经戒烟，它对基因造成的伤害还会保留很长的时间，基因变化会使人患心脏病和癌症。15B推理判断题。由第一段“New research has found
12、that even if you give up smoking, the damage it has done to your genes (基因) will stay there for a much longer time.”可知，新的研究发现，即使你戒烟，它对你的基因造成的损害也会在身体里停留更长的时间。以及下文通过实验说明这一问题的和具体的影响，所以第一段点明了短文的主题，同时第1段的作用也是引起读者的兴趣。故B选项正确。16C细节理解题。由第三段“Some people may have had the changes when they were born, but most p
13、eople get them in their daytoday lives while doing things like smoking.”可知，有些人可能在出生时基因就已经发生了变化，但大多数人的基因变化是日常生活中如吸烟所导致的。所以大多数人的基因变化是日常生活中不良的生活习惯导致的。故C选项正确。17B词义猜测题。由第四段“Its almost like leaving a footprint on wet cement (水泥) it will always be there, even when youve walked away and when the cement beco
14、mes dry.”可知，这几乎就像在湿水泥上留下一个脚印，即使当你走了，当水泥变干的时候，它会一直在那里。所以第4段中带下划线的“it”一词是指“足迹”。故B选项正确。18D细节理解题。由最后段“the findings could help scientists invent medicine to treat genetic damage caused by smoking or find ways to tell which people have heart disease or cancer risks.”可知，这项发现可以帮助科学家发明药物来治疗吸烟造成的基因损伤，或者找到方法来判
15、断哪些人患有心脏病或癌症。所以D选项“这些发现有助于找到治疗吸烟引起的基因损伤的方法”是正确的。故D选项正确。BJuly 20, 1969 is a day that will forever go down in the history books as a day that changed the world forever. That was the day when American astronaut and explorer Neil Armstrong was the first person to set foot on the moon.The moon is located

24、位宇航员。20A词义猜测题。根据语境及第一段末句可知，当阿姆斯特朗踏上月球时，说道：“对一个人来说，这是小小的一步；但对人类来说，这是一个巨大的飞跃。”故此处指代人类首次登上月球这一历史性的时刻。21D细节理解题。根据第三段的Michael Collins，the third member of the crew，remained in the command module during this time可知应选D项。22D推理判断题。根据第四段的.to be sure they were not carrying any unknown diseases or illnesses可知，他们
