2.北京七年级下英语试题 篇二

七年级英语教学, 对我们万州的农村孩子来讲, 是新增设的一门学科, 也是一门新的语言, 所以, 在教学上不同于我们母语的教学。通过大半学期的新教材教学实践, 有以下一些感悟。

一、适宜采用“慢、细、严、勤”的启蒙教学

“慢”, 主要是由于英语不在平常生活中运用, 是一门新的语言, 一下难以接受。但七年级学生正处少年时期, 有好奇心和极强的模仿力, 只要适应后学起来很快。所以, 在教学时必须要慢———语速慢、进度慢、对学生的期望值上也要“慢”。

“细”, 就是指我们要仔细讲解重要的关键的知识点。要不厌其烦地练习重要句型。要耐心细致地指导每个小组积极活跃地参加讨论合作学习。还要求每个小组汇报他们的所学所得, 以及还有没有未掌握的知识点。再让大家来讨论解决, 通过这种方式会让他们把知识记得更牢。

“严”, 主要体现在教学时要严格管理学生, 专注学习, 力求当堂消化。新课程标准倡导的“合作学习”没有淡化课堂纪律的要求, 英语教师要严格要求自己的教学标准, 比如, 规范学生书写、答题格式, 常规的检查及时督促等都能给学生以潜移默化、润物无声的影响。

“勤”, 是指在七年级开始学英语的学习中更要勤记勤练。早读时, 要求课代表来教其他的学生朗读, 之后再领读、齐读, 从而达到背诵的目的。早自习还要检查预习情况。课堂中要规范指导等, 要求我们耐心、细心、勤奋, 坚持一段时间 (至少一个月) 之后, 学生的各种习惯就会被领上路。今后他们就会比较轻松地、快乐地学习英语。

二、研读文本, 把握教学重难点

七年级作为英语入门阶段, 熟记课本要求的单词和短语是首关, 先要学生争取发音, 再划分好记忆掌握的音节。建议学生不单用一种方法记忆, 尽可能地结合两种以上的方法去记, 更重要的是要努力激发学生的识记灵感。如, 在记好词语和情景交际语的基础上, 最重要的是掌握好一般现在时的一般疑问句和否定句的变法。笔者认为这是七年级初始教学的重点。

三、熟悉学情, 早培养一批英语领跑者

学生熟悉老师容易, 而老师在七年级要熟悉学生显得较难。若要尽快熟悉学情, 这就需要我们七年级教师一边教书一边了解学生, 平时勤提问, 熟悉名字, 熟悉脾性, 早点培养一批英语爱好者, 给老师减压, 给其他同学领路。要培养英语爱好者, 我们要利用“伯乐相马, 赛场选马”的方法, 力求培养一批德才兼备的英语爱好者。

四、投入情感, 抓好“培优扶后”工作

英语领跑者培养起来后, 等于优生就培养起来了。接下来要做的事就是要避免两极分化, 别一开始就有一部分人落后, 要做到这些关键就在于要耐心地激励后进生, 让他们多用课余时间, 多读多记多背, 迎头赶上来。在与后进生进行情感沟通时, 教师必须把握好语言分寸。特别是在课堂上提问时, 如果学生一下回答不上来的话, 我们可以说“Think hard, next time you will be better.”还可使用其他鼓励的语言来鞭策学生的努力。这就能让他们下次更勇敢大胆积极地回答任何问题。我们还要注重评价, 学会反思。评价可以使学生认识自我, 树立自信, 对学习落后的学生更有助于树立信心, 也有助于提高学习效率。教学中我坚持随堂练习与口头评价、等级评价、学生间互评并举。我还重视形成性评价。对学生在学习过程中的表现, 以及他们的情感、态度、策略等进行全面评价, 及时发现学生的闪光点, 帮助他们明确方向, 鼓励他们不断进步。我们还应“诲人不倦”, 一定会有“柳暗花明又一村”的收获。英语教育教学, 不能只盯住班级那几个尖子生, 更重要的是抓一批学习后进生让他们先合格后优秀, 这才是我们教育教学的价值所在。

总之, 在新课标指导下的七年级英语教学, 采用“慢、细、严、勤”的启蒙教学, 研读文本把握教学重难点, 熟悉学情, 早培养一批英语领跑者, 投入情感, 抓好“培优扶后”工作, 有耐心地启发、鼓励、督促学生。培养学生自觉学习的好习惯, 抓住机会及时表扬, 让他们体会到进步的甜蜜, 以期慢慢萌发对英语的兴趣。同时, 用上课激情、课堂教具、谈心交流等方式, 促进学生对英语课堂学习的兴趣。七年级学生正处于少年时期, 进取心是极大的, 只要按照新课标中的教学建议, 教学实践中积极用心, 一定可以给学生奠定一生的良好基础。

参考答案:

一、1. B. 点拨: 因为(±4)2= 16,

所以16的平方根是 ± 4,故应选B;

2. C;

3. B;

4. C. 点拨: 根据题意,

将周长为16cm的△ABC沿BC向右平移2cm得到△DEF,

∴ AD = CF = 2cm,BF = BC + CF = BC + 2cm,DF = AC;

又∵ AB + BC + AC = 16cm,

∴ 四边形ABFD的周长 = AD + AB + BF + DF = 2 + AB + BC + 2 + AC = 20cm.

故应选C;

5. A;

6. C;

7. B;

8. C. 点拨: 设此人从甲地到乙地经过的路程为x千米,

则根据题意,得2. 4( x - 3) ≤19 - 7,

即2. 4x - 7. 2≤12,所以2. 4x≤19. 2,

解得x≤8,因此甲地到乙地路程的最大值为8;

9. D. 点拨: ∵ 汽车的速度为30000/3600=25/3m/s,

∴ 甲汽车通过AB、BC、CD三条道路的时间依次为96s、120s、168s;

乙汽车通过DC、CB、BA三条道路的时间依次为168s、120s、96s.

设每次绿灯亮的时间设置为xs,

由题意,得

13x > 96;

26x < 96 + 120;

37x > 96 + 120;

45x > 168;

58x < 168 + 120;

69x > 168 + 120;

710x < 168 + 120 + 96;

811x > 168 + 120 + 96;

由这八个不等式组成的不等式组的解集为34. 9 < x < 36,

故x = 35,故应选D;

10. C. 点拨:

因为A1,A2,A3,A4的坐标分别为

( 1,1) ,( - 1,1) ,( - 1,- 1) ,( 1,- 1) ;

A5,A6,A7,A8的坐标分别为

( 2,2) ,( - 2,2) ,( - 2,- 2) ,( 2,- 2) ;

A9,A10,A11,A12的坐标分别为

( 3,3) ,( - 3,3) ,( - 3,- 3) ,( 3,- 3) ;

通过这些数可得出规律: 每4个数一循环,余数是几就与第几个数的坐标符号是一样的,55 ÷ 4 = 13…3,所以符号应该与第3个一样,即横、纵坐标都为负数,坐标是13是最后一个数应该为52,坐标是14的最后一个数应该为56,所以A55的横、纵坐标都应该是14,即顶点A55的坐标为( 14,14) . 故应选C.

二、11. ( - 5,- 3) ;

12. 1、20% . 点拨: 各小组的百分比之和等于1,该小组的百分比为: 4 ÷ 20 = 20% ;

13. 80°、80°、100°.

点拨: 如图,因为∠2 = 100°,

所以∠3的同位角∠4 = 180° - 100° = 80°,

∠3的内错角∠5 = ∠4 = 80°,

∠3的同旁内角∠6 = ∠2 = 100°;

14. 4 - . 点拨: AB之间的距离为:,因为点B是A、C的中点,所以点C对应的实数为:

15. 34. 点拨: 无限循环小数是有理数,所以1错误; 5的算术平方根是,所以2错误; 27的立方根是3,所以3正确; 要使有意义,必须x + 1≥0,即x≥ - 1,所以4正确; 与数轴上的点一一对应的数是实数,所以5错误;

16. - 1.

点拨: 解关于x,y的二元一次方程组{x + y = k,x - y = 9k,

得{x = 5k,y = - 4k代入方程x + 3y = 7,

得5k - 12k = 7,解得k = - 1;

17. 因为已知程序的运算顺序为: x × 3 - 2,

所以当输入的x = 5时,有5 × 3 - 2 = 13,< 244,

当输入的x = 13时,有13 × 3 - 2 = 63 < 244,

当输入的x = 63时,有63 × 3 - 2 = 187 < 244,

当输入的x = 187时,有187 × 3 - 2 = 559 > 244,

所以若x = 5,则运算进行4次才停止. 若运算进行了5次才停止,

则有第一次结果为3x - 2,

第二次结果为3( 3x - 2) - 2 = 9x - 8,

第三次结果为3( 9x - 8) - 2 = 27x - 26,

第四次结果为3( 27x - 26) - 2 = 81x - 80,

第五次结果为3( 81x - 80) - 2 = 243x - 242,

所以解得2 < x≤4;

18. 7 或 9 或 6 或 10.

点拨: 解方程组,得当y是整数时,m - 8 = ± 1或 ± 2,

解得m = 7或9或6或10.

当 m = 7 时,x = 9; 当 m = 9 时,x = - 7; 当 m = 6 时,x = 5;

当 m = 10 时,x = - 3.

故 m = 7 或 9 或 6 或 10.

三、19. 由题意,得

20. 设一枚壹元硬币x克,一枚伍角硬币y克,则根据题意,得

答: 一枚壹元硬币6. 1克,一枚伍角硬币3. 8克.

21. ( 1) 证明: 六边形的内角和为( 6 - 2) × 180° = 720°.

因为六边形ABCDEF的内角都相等,

所以每个内角的度数为720° ÷ 6 = 120°.

又因为∠DAB = 60°,四边形ABCD的内角和为360°,

所以∠CDA = 360° - ∠DAB - ∠B - ∠C = 360° - 60° - 120° - 120° = 60°,

所以∠EDA = 120° - ∠CDA = 120° - 60° = 60°,

所以∠EDA = ∠DAB = 60°,

所以AB∥DE( 内错角相等,两直线平行) .

( 2) EF∥BC,AF∥CD,EF∥AD,BC∥AD.

22. ( 1) 根据实数的除法法则: 同号两数相除得正数,异号两数相除得负数,因此,原不等式可转化为:

解1,得 -5/2< x≤4;

解2,得无解. 所以原不等式的解集是 -5/2< x≤4.

( 2) 根据实数的除法法则: 同号两数相除得正数,异号两数相除得负数,因此,原不等式可转化为:

解1,得 x > 3; 解2,得 x < - 2.

所以原不等式的解集是x > 3或x < - 2.

23. ( 1) 设搭建A种园艺造型x个,则搭建B种园艺造型( 50 - x)个,则根据题意,得

解得31≤x≤33,所以可设计三种搭配方案:

1A种园艺造型31个,B种园艺造型19个;

2A种园艺造型32个,B种园艺造型18个;

3A种园艺造型33个,B种园艺造型17个.

( 2) 由于搭配一个A种造型的成本是200元,搭配一个B种造型的成本是360元,所以搭配同样多的园艺造型A种比B种成本低,则应该搭配A种33个,B种17个. 即最低成本为33 × 200 + 17 × 360 = 12720( 元) .

24. ( 1) 因为C小组的人数为5人,占被抽取人数的20% ,且前三组的频数之比为9∶ 4∶ 1,所以5 × 4 ÷ 20% = 100( 人) ,所以本次抽取的人数为100人.

( 2) 依题意,得A小组的学生数 = 5 × 9 = 45人,所占比例为45/100×100% = 45% ; C小组的学生数是5人,所占比例为5/100×100%=5%;D小组的学生数=100-45-5×4 - 5 - 100 × 18% = 12( 人) ,所占比例为12/100× 100% = 12% . 所以补全直方图的高度为12,如图中的阴影部分; 扇形统计图中A区域、C区域、D区域所占的百分比分别为A: 45% 、C: 5% 、D: 12% .

( 3) 答案不惟一,只要看法积极向上均可. 如,迷恋网络的人比较多,我们要注意合理使用电脑. 等等.

25. ( 1) 1∠AED = 70°; 2∠AED = 80°;

3猜想: ∠AED = ∠EAB + ∠EDC.

证明: 过点E作EF∥DC,则∴ ∠DEF = ∠EDC,

又∵ AB∥DC,∴ AB∥EF,∴ ∠AEF = ∠EAB,

∵ ∠AED = ∠AEF + ∠DEF,

∴ ∠AED = ∠EAB + ∠EDC.

( 2) 根据题意,得点P在区域1时,

如图3,过点P作PG∥AB,

∵ AB∥DC,

∴ PG∥DC,

∴ ∠EPG = 180° - PEB,∠FPG = 180° - ∠PFC,

∴ ∠EPF = 360° - ( ∠PEB + ∠PFC) ; 点P在区域2时,

如图4,过点P作PG∥AB,

∵ AB∥DC,∴ PG∥DC,

∴ ∠GPE = ∠PEB,∠GPF = ∠PFC,

∴ ∠EPF = ∠PEB + ∠PFC; 点P在区域3时,

如图5,过点P作PG∥AB,

∵ AB∥DC,∴ PG∥DC,

∴ ∠GPF = 180° - ∠PFC,∠GPE = 180° - ∠PEB,

∴ ∠GPF - ∠GPE = ( 180° - ∠PFC) - ( 180° - ∠PEB) = ∠PEB - ∠PFC,

即∠EPF = ∠PEB - ∠PFC; 点P在区域4时,

如图6,过点P作PG∥AB,

∵ AB∥DC,∴ PG∥DC,

∴ ∠GPF = ∠PFC,∠GPE = ∠PEB,

∴ ∠GPF - ∠GPE = ∠PFC - ∠PEB,

即∠EPF = ∠PFC - ∠PEB.

26. ( 1) 依题意,得点B( 3,5) .

( 2) 过C作直线CD交AB于D,

由图可知OC = AB = 5,OA = CB = 3.

1当( CO + OA + AD) ∶ ( DB + CB) = 1∶ 3 时,

即( 5 + 3 + AD) ∶ ( 5AD + 3) = 1∶ 3,

所以8AD = 3( 8 + AD) ,解得AD = 4( 不合题意,舍去) .

2当( DB + CB) ∶ ( CO + OA + AD) = 1∶ 3 时,

即( 5AD + 3) ∶ ( 5 + 3 + AD) = 1∶ 3,所以8 + AD = 3( 5AD + 3) ,

解得AD = 4,所以点D的坐标为( 3,4) .

( 3) 由题意,得C'( 0,3) ,D'( 3,2) ,

由图可知OA = 3,AD' = 2,OC' = 3,

27. 分析:

( 1) 根据平行线的性质,

以及等量代换证明∠ADC + ∠C = 180°,

即可证得AD∥BC.

( 2) 由直线AB∥CD,根据两直线平行,同旁内角互补,

即可求得∠ABC的度数,又由∠DBE =1/2∠ABC,

即可求得∠DBE的度数.

( 3) 首先设∠ABD = ∠DBF = ∠BDC = x°,

由直线AB∥CD,根据两直线平行,同旁内角互补与两直线平行, 内错角相等,

可求得∠BEC与∠ADB的度数,

又由∠BEC = ∠ADB,

即可得方程: x° + 40° = 80° - x°,

解此方程即可求得答案.

解: ( 1) AD∥BC. 理由: 因为AB∥CD,

所以∠ADC + ∠C = 180°,

又因为∠A = ∠C,

所以∠ADC + ∠C = 180°,

所以AD∥BC.

( 2) ∵ 因为AB∥CD,

所以∠ABC = 180° - ∠C = 80°,

因为∠DBF = ∠ABD,BE平分∠CBF,

所以∠DBE =1/2∠ABF +1/2∠CBF =1/2∠ABC = 40°.

( 3) 存在. 理由: 设∠ABD = ∠DBF = ∠BDC = x°.

因为AB∥CD,

所以∠BEC = ∠ABE = x° + 40°,∠ADC = 180° - ∠A = 80°,

所以∠ADB = 80° - x°.

若∠BEC = ∠ADB,则 x° + 40° = 80° - x°,

解得x° = 20°,所以存在∠BEC = ∠ADB = 60°.

点评: 此题考查了平行线的性质与平行四边形的性质. 此题难度适中,解题的关键是注意掌握两直线平行,同旁内角互补与两直线平行, 内错角相等定理的应用,注意数形结合与方程思想的应用.

28. ( 1) 设新建一个地上停车位需x万元,新建一个地下停车位需y万元,则根据题意,得

答: 新建一个地上停车位需0. 1万元,新建一个地下停车位需0. 4万元

( 2) 设新建m个地上停车位,则根据题意,得

10≤0. 1m + 0. 4( 50 - m) ≤11,解得30≤m <100/3.

因为m为整数,所以m = 30或m = 31或m = 32或m = 33,

对应的50 - m = 20或50 - m = 19或50 - m = 18或50 - m = 17,

所以,有四种建造方案.
