2023-2024学年深圳市七年级(下)期末数学试卷

2023-2024学年深圳市七年级（下）期末数学试卷

初一  |  数学  |  期末  |  下学期  |  深圳市

考察知识点

核心整式与因式分解——乘法公式、因式分解三大方法的综合运用
核心平行线与三角形——判定与性质定理、三角形内角和与全等初步
核心实数——平方根、立方根与无理数的概念及运算
重点二元一次方程组——代入法、加减法求解与实际应用
重点不等式与不等式组——解一元一次不等式组并用数轴表示
重点数据的收集与整理——频率、频数与统计图表判读
基础轴对称图形——对称轴的判断与对称图形的识别
基础概率初步——必然事件、不可能事件与随机事件

中考权重

选择题（8-10题，共24-30分）28%
填空题（6-8题，共18-24分）22%
解答题（6-8题，共50-58分）50%

重点题型

解答题 · 二元一次方程组与不等式综合应用难

以深圳市实际生活情境为背景，用方程组和不等式解决商品定价、行程规划等问题，考查建模能力。

解答题 · 三角形全等证明中

利用SSS、SAS、ASA、AAS等判定方法证明三角形全等，推导边角关系。

选择题 · 实数运算与轴对称判断易

平方根计算、无理数判断与轴对称图形识别。

命题趋势

① 期末考试覆盖全册6-7章内容——深圳市试卷注重知识的综合运用

② 以深圳本地活动（花展、运动会等）设计情境化应用题

③ 压轴题常考方程组与不等式的综合应用或几何证明与计算结合

备考策略

① 期末复习需系统覆盖全册内容——建议按章节制作知识导图
② 方程组解题方法选择：系数简单用代入法，系数对称用加减法
③ 几何证明写全过程——已知条件→推理步骤→结论，每步标注定理依据
