全国初二数学竞赛试题及答案解析
全国初二数学竞赛试题及答案解析一、选择题(每题3分,共30分)1. 若a、b、c是三角形的三边长,且满足a^2 + b^2 = c^2,那么这个三角形是:A. 直角三角形B. 锐角三角形C. 钝角三角形D. 不规则三角形答案:A解析:根据勾股定理的逆定理,如果三角形的两边的平方和等于第三边的平方,那么这个三角形是直角三角形。
2. 已知x^2 - 5x + 6 = 0,求x的值。
A. 1B. 2C. 3D. 6答案:C解析:这是一个二次方程,可以通过因式分解法求解。
x^2 - 5x + 6 = (x - 2)(x - 3) = 0,解得x = 2 或 x = 3。
...30. 已知一个数列的前三项为2, 3, 5,且每一项都是前两项的和,求第10项的值。
答案:55解析:这是一个斐波那契数列,每一项都是前两项的和。
根据数列的规律,可以依次计算出第10项的值为55。
二、填空题(每题4分,共20分)31. 如果一个圆的半径是r,那么它的面积是______。
答案:πr^232. 一个长方体的长、宽、高分别是a、b、c,它的体积是______。
答案:abc...三、解答题(每题10分,共50分)36. 已知一个等腰三角形的底边长为10厘米,两腰的长度相等,且底角为45度。
求这个等腰三角形的面积。
答案:25√2解析:首先,根据底角为45度,我们可以知道这是一个等腰直角三角形。
根据勾股定理,两腰的长度为底边的√2倍,即10√2厘米。
然后,根据三角形面积公式(底×高÷2),面积为10×(10√2)÷2=50√2平方厘米。
37. 一个数的平方减去这个数等于36,求这个数。
答案:9 或 -4解析:设这个数为x,根据题意,我们有x^2 - x - 36 = 0。
这是一个二次方程,可以通过因式分解法求解:(x - 9)(x + 4) = 0。
解得x = 9 或 x = -4。
...结束语:本次全国初二数学竞赛试题涵盖了代数、几何、数列等多个领域,旨在考察学生的数学基础知识和解题能力。

初二语数外三科联赛语文专题训练题附答案
初二语数外三科联赛语文专题训练题记叙文专题训练:(一)说荷(赵文美)无数次邂逅荷,从未像现在这样令我心灵的震撼。
这个夏天,天大旱,烈日炙烤着大地,热浪蒸腾着大地。
渐渐地,碧波荡漾的湖泊干涸了……此时此刻,荷临危不惧,坦然自若,正满面春风地迎接着更严酷的考验的到来。
这是怎样一番惊人的情景!往日蓄得一池清洌洌碧水的荷塘滴水不见,在早已焦渴得干巴巴龟裂的土地上,一群群壮硕挺拔的荷昂扬如常地站立,周围还有倔强地从地缝中钻出尖尖角的小荷。
原来在水里生水里长的荷,虽无雨洗尘、无水滋润,田田荷叶依然绿干亭亭翠叶如盖,片片相连相拥相依,充溢着一派勃勃生机;一枝枝饱满的花蕾、粉荷初露的莲花,在灼灼阳光下,显得出奇的艳丽、鲜亮,婀娜多姿地摇曳在清新、生动的碧绿中,丰润鲜灵有流香。
荷,在恶劣的环境中创造着生命的奇迹,它勃发的英姿,是对虐肆旱魔的冷冷嘲讽,更是不言屈服的顽强抗争。
早就听说过荷的故事。
一颗在地层深处沉睡几千年的古莲子,一经挖出,只要给它充足的阳光和水分,它便奇迹般地生长出绿叶,绽放花朵,结出果实。
这就是生命甘泯灭的勇敢而执著的荷。
惟有它在风风雨雨的岁月中,卓然傲立,风吹不退缩,雨淋不着痕,一副以不变应万应的王者风仪。
生命的高贵、圣洁与它不屈不挠的精神伟力相伴相随。
每有狂风袭来,静静的荷便如千万勇士高举着盾牌,凝聚起强大的力量,战无不胜。
最终,狂妄的风在它的面前乖乖地败退。
荷,静立如山,依然故我。
若遇暴雨突至,秋雨绵绵,站成一林舞姬的荷,便如玉指纤纤弹起无数古筝,那顿挫有致、浸透着生命高贵气息的缕缕清音,似一朵朵初绽的音符,挟着荷空灵、洒脱的美韵轻轻飞扬。
“秋阴不散霜飞晚,留得残荷听雨声。
”活得精精神神,活得清清白白,即使红颜青春不在,生命的歌也是回肠荡气,掷地有声。
当凛冽的寒风裹着雪片飞来,在荷的周围疯狂地咆哮、翻卷时,荷的叶,被撕碎了,荷的枝,被折断了。
荷还是不肯摧眉折腰,还是不肯跪倒于地,惟见冰天雪地屹立着它独立自尊、不馁不屈的铮铮傲骨。
