已知:p:|1-|≤2,q:x2-2x+1-m2≤(m>0),若 p是q的必要而不充分条件,求实数m的取值范围. 答案:思路解析:将“若p是q的必要而不充分条件转化为“pp”,进而转化为与其等价的“pq”,再求解.解:由x2-2x+1-m2≤0,得1-m≤x≤1+m.∴q:A={x|x>1+m,或x<1-m,m>0}.由|1-|≤2,得-2≤x≤10.∴p:B={x|x<-2,或x>10}.∵p是q的必要不充分条件,∴ AB.如图.∴解得m≥9.任务型阅读 先通读下面的短文,然后根据短文内容和表格,在空格内填入一个适当的单词,使意思完整.Learning can take place in a classroom, in a meeting room, or even on a ship.
