Question

20．Boys do best with"as few girls as possible"in English lessons at primary and secondary school，Steven Proud，a research student at Bristol University，will tell the Royal Economic Society's conference．But when it comes to maths and science，both boys and girls at primary school achieve up to a tenth of a grade more when there is a high proportion（比例） of girls in the class，Proud found．
Proud tracked boys'and girls'test results at the ages of seven（是否改为阿拉伯数字7为好，与后面对应），11，14 and 16 in 16，000 schools in England between 2002 and 2004 for his PhD．He analysed the test scores to see whether the proportion of girls in a year group made a difference to the results of both genders in maths，science and English．Boys consistently perform up to a tenth of a grade worse when they study English with high numbers of girls as opposed to few or no girls，Proud found．The more girls there are in an English class，the worse boys perform．This is particularly the case in primary schools，he discovered．Girls，who outperform boys in English at every stage at school，are unaffected by the number of boys in their English classes．
He said："The results imply that boys would benefit at all ages from being taught English with as small a proportion of girls as possible．In maths and science，the results tend to imply that both boys and girls benefit from having more girls in the classroom．Boys may do worse in English when there is a high proportion of girls in their class because they realise that the girls are better than them and feel defeated．"

45．The passage mainly talks about．B
 A．the problem of the class sizes  
 B．girls'influence on boys in school
 C．the genders of the students in the class
 D．the reasons why boys do worse in English

 A．in primary schools                           B．in secondary schools
 C．at every stage of school                     D．in high schools
47．Proud discovered that in maths and scienceB．
 A．girls always perform better than boys
 B．having more girls in the class has a positive effect on both boys and girls
 C．boys can benefit a lot more than girls with more girls in the class
 D．boys achieve up to a tenth of a grade worse than girls when there're few or no girls in the class
48．The reason why boys are worse at English with a high proportion of girls in the class is thatA．
 A．boys are discouraged by how well girls are doing in English
 B．boys show less passion for English study than girls
 C．girls are more willing to observe the classroom discipline

Answer 1

分析 研究人员今天宣称，当班上女生人数较多时，男生的英语就会变得较差．而人们以往普遍认为，在学校中，女生对男生总是有积极影响．布里斯托大学的研究生史蒂文•普劳德将在皇家经济学会的会议上宣布：对于小学与初中的英语课而言，女生越少，男生成绩越好．然而史蒂文•普劳德同时发现在数学与科学学科上，女生人数多对男女生都有积极影响--成绩可以提高10%.2002年至2004年间，普劳德为了完成他的博士研究课题，跟踪查询了英格兰16000所学校里7岁、11岁、14岁、16岁的男女生测试成绩．普劳德发现，相对班上没有或者有很少女生的班级而言，当班上女生人数较多时，男生的英语成绩总是会下降10%．普劳德发现，这种现象在小学尤其明显，女生越多，男生的英语就学得越差．而女生的英语成绩则不受男生人数影响，她们在学校的所有学习阶段英语表现都要强过男生．普劳德称："研究结果表明，如果能降低英语课上的女生人数比例，所有年龄组男生的英语成绩都将受益．在数学和科学学科上，研究结果表明女生多对班级中的男女生都有好处．当班里女生比例高时，男生的英语成绩会更差，因为他们意识到女生比他们做得好而感到受挫．"

解答 B篇：45-48：BABA
45题答案是B．考查文章大意．整篇文章讲述了学校里女生数量多少对男生的英语，数学等成绩的影响．故答案是B．
46题答案是A．考查细节．根据This is particularly the case in primary schools，he discovered可知这种现象在小学尤其明显，女生越多，男生的英语就学得越差．故答案是A．
47题答案是B．考查细节．根据In maths and science，the results tend to imply that both boys and girls benefit from having more girls in the classroom．可知在数学和科学学科上，研究结果表明女生多对班级中的男女生都有好处．故答案是B．
48题答案是A．考查细节．根据Boys may do worse in English when there is a high proportion of girls in their class because they realise that the girls are better than them and feel defeated可知当班里女生比例高时，男生的英语成绩会更差，因为他们意识到女生比他们做得好而感到受挫．故答案是A．

点评 本文讲述了女生数量对男生英语数学等成绩的影响．题目涉及多道细节理解题，做题时需要结合原文和题目有针对性的找出相关语句进行仔细分析，结合选项选出正确答案；考查文章大意的题则需要对整篇文章的中心有深刻的理解，进而结合选项选出正确的答案．
