七年级数学经典练习（1） 绝对值专题练习 1、同学们都知道，|5﹣（﹣2）|表示5与﹣2之差的绝对值，实际上也可理解为5与﹣2两数在数轴上所对的两点之间的距离。试探索： （1）求|5﹣（﹣2）|= _________ ． （2）设x是数轴上一点对应的数，则|x+1|表示_______ 与_ __ 之差的绝对值。（3）若x为整数，且|x+5|+|x﹣2|=7，则所有满足条件的x为____ ___ __ 。 2、小刚在学习绝对值的时候发现：|3﹣1|可表示数轴上3和1这两点间的距离；而|3+1|即|3﹣（﹣1）|则表示3和﹣1这两点间的距离．根据上面的发现，小刚将|x﹣2|看成x 与2这两点在数轴上的距离；那么|x+3|可看成x与_________ 在数轴上的距离。请你借助数轴解决下列问题 （1）当|x﹣2|+|x+3|=5时，x可取整数_________ （写出一个符合条件的整数即可）；（2）若A=|x+1|+|x﹣5|，那么A的最小值是_________ ； （3）若B=|x+2|+|x|+|x﹣1|，那么B的最小值是_________ ，此时x为_________ ；（4）写出|x+5|+|x+3|+|x+1|+|x﹣2|的最小值． 3、试求|x﹣1|+|x﹣3|+…+|x﹣2003|+|x﹣2005|的最小值． 4、若ab＜0，试化简++．
5、化简：|3x+1|+|2x-1| 6、若2x+|4-5x|+|1-3x|+4的值恒为常数，求x满足的条件及此常数的值。 7、如果0＜p＜15，那么代数式|x－p|＋|x－15|＋|x－p－15|在p≤x≤15的最小值( ) A． 30 B． 0 C． 15 D．一个与p有关的代数式 8．已知(|x＋l|＋|x－2|)（|y－2|＋|y＋1|）（|z－3|＋|z＋l|）＝36，求x＋2y＋3z的最大值和最小值. 9．电子跳蚤落在数轴上的某点k0，第一步从k0向左跳1个单位得k1，第二步由k1向右跳2个单位到k2，第三步由k2向左跳3个单位到k3，第四步由k3向右跳4个单位到k4…按以上规律跳100步时，电子跳蚤落在数轴上的点k100新表示的数恰好19.94，试求k0所表示的数.
新高考地理非选择题综合限时练1 1.(2020·广西南宁测试)阅读图文材料,回答下列问题: 莫索湾地区位于新疆天山北麓准噶尔盆地南缘,该地区短命植物种类丰富,药用价值高。短命植物属浅根系草本植物,在气温和水分条件合适时,在短短两个月左右时间里迅速绽放,与其他鲜花一起构成“花海”,随后整个植株或地上部分干枯死亡,以种子或地下器官休眠的方式来度过不利季节。下图为莫索湾地区位置图。 (1)推测莫索湾地区短命植物开花季节并分析此时段生长旺盛的原因。 (2)请对莫索湾地区短命植物属“浅根系”草本植物作出合理解释。 (3)请用自然地理环境整体性原理分析莫索湾短命植物休眠期的自然特征。 (4)简要说明莫索湾地区短命植物对当地产业发展的有利影响。 2.(2020·广东深圳二模)阅读图文材料,回答下列问题: 生物医药是北京市“十二五”期间鼓励发展的高新技术产业,但其产业链上游的原料药生产属于不符合北京当前功能定位的一般性制造业。我国医药行业实行属地管理,药企必须在注册地生产和接受监管,一旦搬到异地,只能重新进行药品审批(审批时间一般要持续两年到三年)。京冀两地在沧州合作共建共管首个专业化产业园——北京·沧州渤海新区生物医药产业园(下图),保留转移医药企业
的“北京户口”即相应产品批准文号不变。这种创新模式促使越来越多的北京医药企业迁往沧州,形成了独具特色的“研发在北京,成果转化在沧州”的发展格局。 (1)说明北京的原料药生产企业在共建共管政策引导之前外迁可能面临的风险。 (2)与北京相比,分析北京·沧州渤海新区生物医药产业园成为北京市原料药企业承接基地的主要区位优势。 (3)简述北京原料药企业将产品研发与销售部门保留在北京的主要原因。 (4)指出沧州生物医药产业园区对促进当地产业升级的作用。

强化技能限时训练(十四) 阅读理解(主旨大意类)+阅读填句 (限时35分钟) Ⅰ.阅读理解 ( A ) 【社会文化类】 I am a strong believer that if a child is raised with approval,he learns to love himself and will be successful in his own way. Several weeks ago,I was doing homework with my son in the third grade and he kept standing up from his chair to go over the math lines. I kept asking him to sit down,telling him that he would concentrate better.He sat but seconds later,as if he didn’t even notice he was doing it,he got up again. I was getting frustrated,but then it hit me. I started noticing his answers were much quicker and accurate when he stood up. Could he be more absorbed while standing up? This made me start questioning myself and what I had been raised to believe. I was raised to believe that a quiet,calm child was a sure way to success. This child would have the will power to study hard,get good grades and become someone important in life. Now those same people perhaps come to realize that their kids are born with their own sets of DNA and personality qualities,and all you can do is loving and accepting them. As parents,throughout their growing years and beyond that,we need to be our kids’ best cheerleaders,guiding them and helping them find their way. I have stopped asking my son to sit down and concentrate. Obviously,he is concentrating just in his own way and not mine. We need to learn to accept our kids’ ways of doing things. Some way may have worked for me but doesn’t mean we need to carry it through generations. There is nothing sweeter than being personal and unique.It makes us free and happy and that’s just the way I want my kids to live their own lives. 1.Time and again the author got his son seated in order to make him . A. work fast B. go polite C. stay relaxed D. keep attentive 2.The underlined “it” (in the first paragraph) probably refers to . A. his son’s doing better while standing up B. his failure in keeping his son under control C. his own experience as a school boy D. his disappointment with his active child 3.By this passage,the author attempts to tell other parents to . A. correct their kids’ manners from the early ages B. respect and trust their kids’ ways of behaviors C. develop a good relationship with their children D. guarantee their children’s freedom at home 4.Which of the following would be the best title of the passage?( ) A. Parental help with teens’ study B. Adult influence on teen growth C. Kids’ success in their own styles D. Friendship between generations
