Scores on a national test released(发布)on November 1 show that students in the U.S.A. have improved in math over the last two years, but mostly stayed the same in reading. This year, 422,000 fourth graders and 343,000 eighth graders took the exams between January and March. Students were asked to read grade-appropriate(年级适合的) materials and answer questions for the reading test. For the math test, students answered questions about geometry, algebra, number properties, measurement and other topics.
The U.S Department of Education released the scores in a report called The Nation’s Report Card (NAEP). This year, students earned the highest scores ever recorded on the math exam, which has been given since 1990.Fourth graders scored an average of 241.That is a one-point increase from 2009and a 28-point increase from 1990. Eighth graders made similar progress. Then average score this year was 284,up one point from 2009 and 21 points from 1990.
In reading, fourth graders scored an average of 221 points, the same average score since 2007.That score is four points above those from 1992, when the first reading test was given. Eighth graders scored an average of 265 points, up one point from 2009 and five points from 1992.
Education experts say reading is a harder subject to improve in the classroom than math. While math is largely learned in classrooms, reading results depend on how much kids read outside of school and how much they read in other subjects, such as history and science.
On the NAEP, math scores were the highest among students who have limited use of calculators(计算器) during math lessons, compared with students who have unlimited use or no use. Reading scores were the highest among students who said they read for fun on their own time almost every day.
【小题1】According to the test, students in the U.S.A .A．do better in math than in readingB．work harder at reading than at mathC．prefer to learn math in their spare timeD．are more interested in reading than before【小题2】In 1990, the fourth graders’ average score on the math exam was about A．238B．240C．213D．220【小题3】We can learn from the third paragraph that .A．eighth graders all took part in the test in 2007B．reading scores have not improved much since 2007C．eighth graders got higher scores than fifth gradersD．fourth graders’ scores are becoming lower and lower【小题4】 What can we learn from the passage?A．The first reading test was given in 1990.B．Eighth graders’ average math score was 285 in 2009C．Eighth graders got the same average as fourth graders in the reading this yearD．Reading is hard to improve in the classroom because that requires students to read a lot outside of school.A

(答案→)A 解析：文章介绍美国公布全国学生的数学和阅读考试的平均分，可以看出，学生在数学方面有了很大的进步，但是阅读没有，专家解释这是因为阅读能力的提高要求学生在课外大量阅读。【小题1】细节题：从第一段的句子：Scores on a national test released(发布)on November 1 show that students in the U.S.A. have improved in math over the last two years, but mostly stayed the same in reading.可知学生的数学比阅读好，选 A【小题2】计算题：从第二段的句子：Fourth graders scored an average of 241.That is a one-point increase from 2009and a 28-point increase from 1990. 可知1990年四年级学生的平均数学成绩是241-28=213，选C 【小题3】细节题：从第三段的句子：In reading, fourth graders scored an average of 221 points, the same average score since 2007可知从2007年学生的阅读能力没有什么提高。选B【小题4】细节题：从第四段的句子：Education experts say reading is a harder subject to improve in the classroom than math. While math is largely learned in classrooms, reading results depend on how much kids read outside of school and how much they read in other subjects, such as history and science.可知阅读能力不容易提高，因为这要求学生在课外大量阅读。选D。
