ACT数学考试练习题重点题目

　　ACT考试已经成为大多学生申请美国留学的首选。要想顺利通过考试，就要先了解考试内容，然后进行分解练习，加以熟悉ACT考试。美国ACT考试中，数学部分应该算是比较简单的了。下面是ACT数学部分的考试提纲以供大家参考。

　　In the Mathematics Test, three subscores are based on six content areas:

pre-algebra, elementary algebra, intermediate algebra, coordinate geometry,

plane geometry, and trigonometry.

　　做过ACT考试练习题的朋友不难发现，美国ACT考试数学部分，共六个方面的内容组成了三个部分的得分：算术、初级代数、中级代数、几何坐标、平面几何、三角形。

　　· Elementary Algebra (17%)。 Questions in this content area are based on

properties of exponents and square roots, evaluation of algebraic expressions

through substitution, using variables to express functional relationships,

understanding algebraic operations, and the solution of quadratic equations by

factoring.

　　· Intermediate Algebra (15%)。 Questions in this content area are based on

an understanding of the quadratic formula, rational and radical expressions,

absolute value equations and inequalities, sequences and patterns, systems of

equations, quadratic inequalities, functions, modeling, matrices, roots of

polynomials, and complex numbers.

　　·

中级代数(15%)：二次方程式公式的理解运用，有理数和根的表达式，绝对值等式和不等式，序列;主程组，二次不等式，函数，建模，矩阵，多项式的根。

　　· Coordinate Geometry (15%)。 Questions in this content area are based on

graphing and the relations between equations and graphs, including points,

lines, polynomials, circles, and other curves; graphing inequalities; slope;

parallel and perpendicular lines; distance; midpoints; and conics.

　　· 几何坐标(15%)：图表，图表与等式的关系，包括点、线、多项式和其他曲线;图表与不等式，斜率，平行线和正交线，距离，中点和圆锥。

　　Plane Geometry/Trigonometry

　　平面几何/三角形

　　· Plane Geometry (23%)。 Questions in this content area are based on the

properties and relations of plane figures, including angles and relations among

perpendicular and parallel lines; properties of circles, triangles, rectangles,

parallelograms, and trapezoids; transformations; the concept of proof and proof

techniques; volume; and applications of geometry to three dimensions.

　　·

平面几何(23%)：平面图形的性质和关系，包括角、平行线和正交线的关系，圆的属性，三角形，矩形，平行四边形，梯形，转化，证明方法，体积，立体几何的运用。

　　· Trigonometry (7%)。 Questions in this content area are based on

understanding trigonometric relations in right triangles; values and properties

of trigonometric functions; graphing trigonometric functions; modeling using

trigonometric functions; use of trigonometric identities; and solving

trigonometric equations.

　　· 三角(7%)：三角关系，三角函数的属性和值，三角函数图，三角函数建模，三角恒等式的运用和解三角等式。

　　备考是除了多做ACT考试练习题外，还可以参加一些系统的考试培训，这样更有助于分数的提高。
