Is your family interested in buying a dog? A dog can be a pleasant companion (伙伴) to your family, but if you choose the wrong kind of dog,you will have a lot of troubles.

Families should sit down and thoroughly discuss the possible problems before buying a dog. Even if the children in your family are the ones who want the dog, the parents are the ones who are really responsible for seeing that the animal is properly cared for. If you don't know much about dogs, it is a good idea to go to the library for books about different kinds of dogs, as well as books about how to train a young dog. In reading about the different breeds (种类) you should know that a dog described (描述) as very alert (机敏灵活的) may be too active.

One of the most popular dogs these days is the German shepherd (牧羊犬). This is because it provides protection as well as companionship (陪伴). The family should be warned that these dogs grow up to be very big, and may be too powerful for children

全国卷2019年高考英语复习题强化技能限时训练(十四)

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

Then she looked at my father and replied, “You are 5 . This is not the worst boy at all, 6 the smartest one who hasn’t yet found an outlet(释放的途径)for his enthusiasm.” Her words began a(n) 7 between us. No one had ever called me smart. My family and neighbors had built me up in my 8 as a bad boy. My stepmother changed all that. She changed many things. She 9 my father to go to a dental school, from which he graduated with honors. She moved our family into a town, where my father’s career could be more 10 and my brother and I could be better 11 .

解析 分层抽样应按比例抽取,所以应抽取三年级的学生人数为200×2 10=40. 答案 B 6.一个单位共有职工200人,其中不超过45岁的有120人,超过45岁的有80人.为了调查职工的健康状况,用分层抽样的方法从全体职工中抽取一个容量为25的样本,应抽取超过45岁的职工________人. 解析 依题意得,抽取超过45岁的职工人数为25 200×80=10. 答案 10 7.某工厂生产A ,B ,C 三种不同型号的产品,产品数量之比依次为 现用分层 抽样方法抽出一个容量为n 的样本,样本中A 种型号产品有16件,那么此样本的容量n =________. 解析 由题意得n =16×10 2=80. 答案 80 8.课题组进行城市空气质量调查,按地域把24个城市分成甲、乙、丙三组,对应城市数分别为4,12,8.若用分层抽样抽取6个城市,则丙组中应抽取的城市数为________. 答案 2 9.某企业有三个车间,第一车间有x 人,第二车间有300人,第三车间有y 人,采用分层抽样的方法抽取一个容量为45人的样本,第一车间被抽取20人,第三车间被抽取10人,问:这个企业第一车间、第三车间各有多少人? 解 x =20×30045-20-10=400(人),y =10×300 45-20-10 =200(人). 10.某单位有工程师6 人,技术员12 人,技工18 人,要从这些人中抽取一个容量为 n 的样本.如果采用系统抽样和分层抽样方法抽取,都不用剔除个体;如果样本容量增加1 个,则在采用系统抽样时,需要在总体中先剔除1个个体,求样本容量n . 解 解法1:总体容量为6+12+18=36(人).当样本容量是n 时,由题意知,系统抽样的间隔为36n ,分层抽样的比例是n 36,抽取工程师人数为n 36×6=n 6人,技术人员人数为n 36×12 =n 3人,技工人数为n 36×18=n 2 人,所以n 应是6的倍数,36的约数,即n =6,12,18. 当样本容量为(n +1)时,总体容量是35 人,系统抽样的间隔为35n +1,因为35 n +1 必须是整数,所以n 只能取6,即样本容量n =6. 解法2:总体容量为6+12+18=36(人). 当抽取n 个个体时,不论是系统抽样还是分层抽样,都不用剔除个体,所以n 应为
