第一类，读题不细心。这是很多同学都会犯的错误，但其实也是最好纠正的问题，关键在于养成细致认真的态度。让我们一起看一个例题：例一：A clerk's salary is $320 after a 25% raise. Before the clerk's raise , the supervisor's salarr was 50% greater than the clerk's salary. If the supervisor also receive a raise in the same amount as the clerk's raise, what is the supervisor's salary after the raise?A 370B 424C 448D 480E 576 这个题目错误率在80%以上，很多同学会选择D选项，而错误的关键是这句话“If the supervisor also receive a raise in the same amount as the clerk's raise”，很多同学会理解为员工和主管获得了同等比例的工资增长，然而实际上same amount 是指的同等数量，我相信amount这个单词是数量的意思，大多数同学是知道的，但是因为思维惯性，而不是基于事实，做出了错误的理解。答案：C
第二类，读不懂题目。这种问题跟学生的阅读能力有一定关系，尤其是在一些结合实际场景的应用题中，最容易出现这种问题。让我们一起看一个例题：例二：For a project in Home Economics class, Kirk is making a tablecloth for a circular table 3 feet in diameter. The finished tablecloth needs to hang down 5 inches over the edge of the table all the way around. To finish the edge of the tablecloth, Kirk will fold under and sew down 1 inch of the material all around the edge. Kirk is going to use a single piece of rectangular fabric that is 60 inches wide. What is the shortest length of fabric, in inches, Kirk could use to make the tablecloth without putting any separate pieces of fabric together?F. 15G. 24H. 30J. 42K. 48这个题目很多同学不太理解，就是因为和实际情况相结合以后变得稍微复杂了一些。简单地讲，就是要给一个圆桌做一个圆形的桌布，桌子直径3英尺（注意等于36英寸，题目最后问得也是英寸），桌布盖在桌子上以后要垂下来5英寸，桌布的边上要留出1英寸用于缝边，最后问如果有一个宽60英寸的布做这个桌布，长最短为多少，可以做出这个桌布，前提是剩下的布料不能拼接到一起，实际上这个题目就是求这个桌布的直径，所以显然是3*12+5*2+1*2=48 inches。答案：K
