One of this summer’s hottest books is “That Guy Was Cool.” Sounds like a great book
for kids, doesn’t it? But parents and teachers want to read this one, too.It can teach them
something about the language of today’s kids.So lots of people, young and old, went to see the book’s author, 19-year-old Korean girl
Guiyeoni, on Saturday.She was in Beijing to sign books for her fans.“Guiyeoni wrote a story that is near to us and goes to our hearts,” said a Junior 2 student
in Beijing.“When I read it, I laughed and I cried.”
Like the “Meteor Garden” TV series, “That Guy Was Cool” tells an unusual story of love
between two students.The girl is sweet, but she’s just average（一般的）.The boy is
good-looking and has everything, but he is often unhappy because his father died when he
was very young.They become close and help each other to be happy.In the end, they fall in
love.“The girl in the book is like me.She’s simple and moody,” said Guiyeoni.Guiyeoni’s book doesn’t only use words.It also uses things like emotions.Emotions are
small icons, like smiling faces, and they are used to show emotions.Kids know what these
things mean, because they often use them when they talk on the Internet or send messages
with mobile phones.Guiyeoni said she wrote this way because of her young readers.“Writing with pictures is
vivid（生动）and can say a lot of things,” she said.Guiyeoni began writing the book’s story on the Web in 2001 when she was a Senior 2
（高二）student.Last year, she put that online story together to make this book.“That Guy
Was Cool” has been made into a film, and it will come out in Korea next month.This is Guiyeoni’s first of four books, and she hopes to keep writing as she goes through
college.She also has a message for young writers.“I think that if they try hard, lots of young
people can do this.”

C.a young writerD.one of the emotions
55.Which of the following may Not be an emotion?

C.pictures can say lots of things
D.she was only a Senior student when she was writing the story

Mobile phone(手机)has become a problem for middle schools.Some middle schools in
Australia have banned(禁止)students from carrying mobile phones during school hours.Mobile phone use among children has become a problem for the school this year.Several
children have got mobile phones as Christmas gifts, and more students will want them.Mary
Bluett, an official, said mobile phone use is a distraction(分心的事)to students during school
hours and it also gives teachers so much trouble in their classrooms.Teachers were also
She said some schools had tried to ban mobile phones.Some parents felt unhappy
because they couldn’t get in touch with their children.Many teachers said students should not have mobile phones at school, but if there was a
good reason, they could leave their phones at school office.They also said there were many
reasons why the students should not have mobile phones at school: they were easy to lose and
were a distraction from studies.Many people say that they understand why parents would want their children to have
phones, but they think schools should let the students know when they can use their mobile
phones.58.We know from the passage that some children get mobile phones from.A.the makers and sellersB.the passers-by and strangers

初二英语竞赛试题 篇2
(一)学生基础不扎实,对英语学习缺乏兴趣
初一的英语侧重交际性,语法和词汇只在小学英语的基础上增加了一小部分,且绝大部分学生都有参加暑期有关小学和中学对接的培训课程,因此对大多数学生来说初一英语相对较简单。但他们仅仅满足于上课能听懂的状态,在知识构成上存在很多漏洞,所获取的语言技能十分薄弱。进入初二后,英语词汇量、课文长度都会大幅度地增加。如新版Go For It教材以话题为体系编排,每个单元相对独立,教材难度的增加大大降低了学生学习英语的兴趣。一旦学生在初二阶段的英语语言技能得不到发展和延续,那英语成绩可想而知。
(二)缺乏良好的学习方法和学习习惯,英语学习日趋被动
良好的学习方法和学习习惯是提高英语学习效率的关键。经过初一一年的学习,学优生已经形成了自己固有且行之有效的方法和习惯,并在英语学习的道路上越走越顺,进入良性循环。可英语学困生英语水平的低能现象简直让老师和家长瞠目结舌。他们怕听、怕说、怕读、怕写、怕问、怕背。这部分学生课前不知道预习,课后也不注意巩固,对课堂上所呈现的知识不能熟练掌握,越学越觉得英语难。对他们而言,学习英语完成处于被动状态,是被家长和老师逼着学的。久而久之就放弃英语学习,造成了两极分化。
(三)学生心理变化迅速,产生厌学情绪
学生进入初二后,在心理和生理两方面都发生了剧变。一方面他们认为自己长大了,能自己做主,但另一方面他们又不能脱离成人而存在。这种半幼稚半成熟的状态极不稳定,他们不再对老师的教导唯命是从,会时不时地以自己的意志来对抗老师枯燥的说教和单一的教学方式。加之周遭新鲜事物对学生的吸引,使得他们无法继续将注意力集中在英语学习之上。长此以往,英语成绩下滑,而教师和父母的不理解甚至是批评责骂则会使情况更为恶化,最后产生厌学情绪。
(四)家校联系断层,没有做到双管齐下
学生进入初二阶段的学习后,家长潜意识里认为自己的孩子已经长大了,不需要自己再像以前那样随时随地地督促。另一方面,学生所呈现出的各种叛逆心理和行为也让家长认为管得太多不好。他们逐渐放松了对孩子的督促,给予孩子更多的自主权,可事实上初二阶段的学生还处于半成熟半幼稚的状态,他们一方面为自己得到更多的自主权而沾沾自喜,另一方面又无法控制自己的学习行为。最后导致家长对孩子在校的学习情况不够了解,缺乏与教师的有效沟通。这在一定程度上影响了学生英语学习成绩的提高。
二、根据以上两极分化原因的分析,结合笔者自身的教学实践,提出减小两极分化的对策
(一)减轻学生英语学习负担,建立轻松和谐的师生关系
相对于初一阶段的学习,学生在初二阶段的学习负担更重。各门课的教材内容变得更加复杂,对学生本身的要求也有了很大的提高,越来越多的作业占用了学生的课余时间。同时,初二阶段学生特有的心理状态使得他们与家长教师的关系慢慢疏远,师生间缺乏有效沟通。作为英语教师,可能我们更侧重英语成绩,而相对忽视了对学生非智力因素的关注,部分学生越来越不喜欢上英语课。所以作为一线英语教师,我们可以针对初二学生特有的心理、生理特点,发动情感攻势,取得与学生的感情共鸣,建立轻松、和谐的师生关系,从而增强学生学习英语的自信心,提高学生英语学习的兴趣。
(二)改善教法,因材施教,实施分层教学
新课程的实施不仅对学生提出了更高要求,对英语教师亦然。学生在初一阶段获得的较为薄弱的语言技能能否在初二的学习过程中得到延续和发展,是缩减英语两极分化的一个重要方面。这就需要英语教师不断改进自己的教学方法,原有的一成不变的教法已不适合现在的学生,也不适合现在的信息技术飞速发展的年代,我们需要给学生营造一种轻松、快乐的学习环境。在实际教学过程中,我们可以针对不同的课型采用不同的方法。如在新授课时借助多媒体创造适宜的教学情境,使学生在不知不觉中掌握英语知识。
总而言之,初二英语学习中出现两极分化的现象不是偶然的,归根结底是由多种因素造成。缩减两极分化的差距是一项任重而道远的工作,需要英语教师、家长及学生本身的高度关注、共同努力。只要找出原因,采取积极措施,对症下药,相信能有效遏制两极分化,从而达到转化学困生、缩小分化的目的,真正走出两极分化的困境。

二、填空题（每小题4分，第15小题，每个空2分，第19小题，答对一个答案2分）
11. 2；12. 2.007×10-4； 13. ； 14. ＞； 15. 6，14； 16. 2.5； 17. 16 ；18. 888； 19. 或； 20. hope.
三、解答题
21.（1）连结CO，易知△AOC是直角三角形，∠ACO = 90O，∠AOC=30O，所以AO = 2AC = 2.
（2）如图1，大六角星形的面积是等边△AMN面积的12倍.因为AM2 =+ ，解得AM = ，所以大六角星形的面积是S = 12××× = 4. （7分）
（3）小六角星形的顶点C到其中心A的距离为，大六角星形的顶点A到其中心O距离为2，所以大六角星形的面积是一个小六角星形的面积的4倍，所以大六角星形的面积∶六个小六角星形的面积 = 2∶3. （10分）
22.（1）由图2知，可设甲车由A地前往B地的函数解析式为 = ，将（2.4，48）代入，解得 = 20，所以 = 20. （2分）
由图2可知，在距A地30千米处，乙车追上甲车，所以当 = 30千米时，=== 1.5（小时），即甲车出发1.5小时后被乙车追上.（5分）
（2）由图2知，可设乙车由A地往B地的函数的解析式为 =+ ，将（1.0，0）和（1.5，30）代入，得解得
所以 = 60. （7分）
当乙车到达B地时， = 48千米，代入 = 60，得 = 1.8小时.又设乙车由B地返回A地的函数的解析式为 =+ ，将（1.8，48）代入得48 =×1.8 + ，解得 = 102，所以 =+ 102. （9分）
当甲车与乙车迎面相遇时，有30 + 102 = 20 ，解得 = 2.04小时，代入 = 20 ，得 = 40.8千米，即甲车与乙车在距离A地40.8千米处迎面相遇.（12分）
（3）当乙车返回到A地时，有30 + 102 = 0，解得 = 3.4小时.甲车要比乙车先回到A地，速度应在大于 = 48（千米/小时）. （15分）
23.（1）平面上恰好有9个点，且平均分成三组，每组3个点，其中每个点可以与另个两组的6个点连接，共有线段 = 27（条）. （5分）
（2）若平面上恰好有9个点，且点数分成2，3，4三组，则平面上共有线段[2×（3 + 4） + 3×（2 + 4） + 4×（2 + 3）] = 26（条）. （10分）
（3）设第一组有个点，第二组有个点，第三组有个点，则平面上共有线段[（ + ） + （ + ） + （ + ）] =++ （条）.
若保持第三组点数不变，将第一组中的一个划归到第二组，则平面上线段的条数为（1）（ + 1） + （ + 1） + （1） =+++ 1，与原来线段的条数的差是1， 即当＞时，1≥0，此时平面上的线段条数不减少；当≤时，1＜0，此时平面上的线段条数一定减少.
由此可见，当从点数较多的一组中划出一个点到点数较少的一组中时，平面上的线段条数不减少，所以当三组中点数一样多（或基本平均）时，平面上线段的条数最多. （13分）
设三组中都有个点，则线段条数为32= 192，解得= 8，所以平面上至少有24个点. （15分）（周敏荐）
