A young girl sits at her desk, reviewing her homework for the evening. English: Read three chapters and write a report. Math: Complete 30 problems. Science: Do a worksheet, front and back. French: (A) Study new words for tomorrow’s test. It’s going to be a long night.
This happens to students in America. Now it’s time to start a homework revolution(变革).
Do students in the United States receive too much homework? According to the National Education Association, a student should be assigned (布置) no more than 10 minutes per grade level per night. For example, a first grader should only have 10 minutes of homework, a (B) grader, 20 minutes, and so on. This means that a student in my grade—seventh—should have no more than 70 minutes of work (C) each night. Yet this is often doubled, sometimes even worse!
It’s no good giving students too much homework. According to research, kids are developing more illness at school, such as stomachaches, headaches and sleep problems than before.
Everybody (D) that teachers are the ones who assign homework, but they are not the only ones to blame (受责备). “Many teachers are under greater pressure (压力) than ever before,” says Kylene Beers, President of the National Council for teachers of English, “Some of (E) it comes from parents, some from the wish for high scores on tests.” Teachers who are under pressure feel the need to assign more homework.
Some people have different ideas, saying that homework prepares kids for doing better in high school, better in college, and (F) 今后找到更好的工作. But too much homework is sapping students’ strength, curiosity（削弱学生的个性和好奇心), and most importantly, their love of learning, is that really what teachers and parents want?
【小题1】写出文中划线部分（A）和（C）的同义词或近义词:
【小题2】在文中（B）和（D）的空白处分别填入适当单词:
【小题3】文中划线部分（E）指代的是:
【小题4】将文中划线部分（F）译成汉语:
【小题5】从文中找出能说明本文主旨大意的中心词: learn; every

(答案→)learn; every 解析：1.study和learn都有学习的意思，可以互换，但learn侧重学习的成果，指从不知到知，从不会到会的学习，强调通过学习去获得知识和技能； study强调学习的过程，指深入系统地学习，带有努力，勤奋的意味。其学习对象往往是科学，艺术和需要深入探讨，研究的问题及学科，不是单纯地获得技巧。Each为每一个的意思，近义词为every.each强调各别、各个，而every 强调全部、都.2. 前一句For example, a first grader should only have 10 minutes of homework,可以看出，一个一年级的学生做十分钟的作业，后一句a student in my grade—seventh—should have no more than 70 minutes of work看出七年级的学生做不超过七十分钟的作业，B处应为二年级，填second.每个人都知道作业是老师布置的，所以D处填knows.3.从前后文可以看出it指的是来自家长和考试分数的压力，所以填pressure，压力.4.本句直接翻译即可，找到工作为get a job,此处不能用work，因为work不可数.5.本文首先说了一个美国的小女孩在做家庭作业，以及家庭作业的情况，第二段说了家庭作业的数量比较多，第三段则分析了这一现状的原因，综合这些应填homework.

这个问题我还想问问老师呢
