精选ACT数学基础练习单选题

　　ACT考试全称“American College Testing”，中文名称为“美国大学入学考试”，是美国大学本科的入学条件之一，也是奖学金发放的重要依据之一。由ACT公司主办。ACT考试分为四个部分：文章改错(English)，数学(Math)，阅读(Reading)，和科学推理(Science Reasoning)。另外，作文为选考。

　　ACT(American College Test)考试与SAT考试均被称为“美国高考”，它们既是美国大学的入学条件之一，又是大学发放奖学金的主要依据之一及对学生综合能力的测试标准。这个考试也被所有美国四年制大学承认，与SAT相比学校没有偏向性，两个考试的成绩均接受。和SAT不同，ACT考试更像一种学科考试，它更强调考生对课程知识的掌握，同时也考虑到了对考生独立思考和判断能力的。从时间上看，ACT考试比SAT紧张;从难度上看，ACT考试比SAT更容易一些，尤其对中国的考生来说，选择ACT考试可能更容易在短期内获得相对满意的成绩!
