21. It is implied in Paragraph 1 that nowadays homework.
- A. is receiving more criticism
- B. is gaining more preferences
- C. is no longer an educational ritual
- D. is not required for advanced courses
答案：A
答案句：Homework has never been terribly popular with students and even many parents, but in recent years it has been particularly scorned.
参考译文：作业从来就不太受学生甚至许多家长的欢迎，但近年来它尤其受到鄙视。
定位线索：题干“nowadays homework”→答案句“in recent years it has been particularly scorned”；文中“particularly scorned”对应选项A“receiving more criticism”（受到更多批评）。
解析：题干问第一段暗示如今作业如何。答案句直接说“in recent years it has been particularly scorned”，即近年来尤其被鄙视，与选项A“receiving more criticism”同义。选项B“gaining more preferences”与原文相反；选项C“no longer an educational ritual”偷换概念，原文说“revising their thinking on this educational ritual”，并非不再是教育惯例；选项D“not required for advanced courses”无中生有，原文只说高级课程例外，并非不要求。
22. L.A. Unified has made the rule about homework mainly because poor students
- A. tend to have moderate expectations for their education
- B. have asked for a different educational standard
- C. may have problems finishing their homework
- D. have voiced their complaints about homework
答案：C
答案句：This rule is meant to address the difficulty that students from impoverished or chaotic homes might have in completing their homework.
参考译文：这一规则旨在解决来自贫困或混乱家庭的学生在完成作业方面可能遇到的困难。
定位线索：题干“mainly because poor students”→答案句“students from impoverished or chaotic homes”；文中“difficulty in completing their homework”对应选项C“may have problems finishing their homework”。
解析：题干问洛杉矶联合学区制定该规则的主要原因。答案句明确说“This rule is meant to address the difficulty...in completing their homework”，即针对贫困学生完成作业的困难，与选项C“may have problems finishing their homework”直接对应。选项A“moderate expectations”无中生有；选项B“asked for a different educational standard”偷换概念，原文是政策暗示降低标准，并非学生要求；选项D“voiced their complaints”无中生有。
23. According to Paragraph 3, one problem with the policy is that it may.
- A. result in students' indifference to their report cards
- B. undermine the authority of state tests
- C. restrict teachers' power in education
- D. discourage students from doing homework
答案：D
答案句：But with homework counting for no more than 10% of their grades, students can easily skip half their homework and see very little difference on their report cards.
参考译文：但由于作业在成绩中占比不超过10%，学生可以轻易跳过一半作业，而成绩单上几乎看不出差别。
定位线索：题干“According to Paragraph 3, one problem”→答案句“students can easily skip half their homework”；文中“skip half their homework”对应选项D“discourage students from doing homework”（打消学生做作业的积极性）。
解析：题干问第三段中政策的一个问题。答案句指出学生可以轻易跳过一半作业且成绩几乎无差别，这直接说明政策会让学生不愿做作业，对应选项D“discourage students from doing homework”。选项A“indifference to their report cards”偷换概念，原文说成绩单上差别小，并非对成绩单冷漠；选项B“undermine the authority of state tests”无中生有；选项C“restrict teachers' power”曲解原文，原文说政策强加统一规则，但未说限制教师权力。
24. As mentioned in Paragraph 4, a key question unanswered about homework is whether
- A. it should be eliminated
- B. it counts much in schooling
- C. it places extra burdens on teachers
- D. it is important for grades
答案：B
答案句：At the same time, the policy addresses none of the truly thorny questions about homework. If the district finds homework to be unimportant to its students’ academic achievement, it should move to reduce or eliminate the assignments, not make them count for almost nothing. Conversely, if homework matters, it should account for a significant portion of the grade.
参考译文：与此同时，该政策没有解决任何关于作业的真正棘手问题。如果学区认为作业对学生的学业成绩不重要，就应该减少或取消作业，而不是让它们几乎不计入成绩。相反，如果作业重要，它就应该在成绩中占重要比例。
定位线索：题干“Paragraph 4, a key question unanswered”→答案句“addresses none of the truly thorny questions”及“if homework matters, it should account for a significant portion of the grade”；文中“account for a significant portion”对应选项B“it counts much in schooling”（作业在学校教育中很重要）。
解析：题干问第四段中关于作业的一个未解答的关键问题。答案句指出政策未解决作业是否重要的问题，并说“if homework matters, it should account for a significant portion of the grade”，即作业是否重要、是否应占大比例，这正是未解答的问题，对应选项B“it counts much in schooling”。选项A“it should be eliminated”是原文提到的可能性之一，但并非未解答的问题；选项C“extra burdens on teachers”无中生有；选项D“it is important for grades”是假设条件，并非问题本身。
25. A suitable title for this text could be
- A. A Faulty Approach to Homework
- B. A Welcomed Policy for Poor Students
- C. Thorny Questions about Homework
- D. Wrong Interpretations of an Educational Policy
答案：A
答案句：Unfortunately, L.A. Unified has produced an inflexible policy which mandates that with the exception of some advanced courses, homework may no longer count for more than 10% of a student’s academic grade. … The homework rules should be put on hold while the school board, which is responsible for setting educational policy, looks into the matter and conducts public hearings. It is not too late for L.A. Unified to do homework right.
参考译文：不幸的是，洛杉矶联合学区制定了一项不灵活的政策，规定除一些高级课程外，作业在学业成绩中的占比不得超过10%。……作业规则应暂缓实施，同时负责制定教育政策的学校董事会应调查此事并举行公开听证会。洛杉矶联合学区现在改正作业政策还为时不晚。
定位线索：题干“suitable title”→答案句“inflexible policy”及“should be put on hold”；文中“inflexible policy”对应选项A“A Faulty Approach to Homework”（有缺陷的作业处理方式）。
解析：题干问适合本文的标题。文章首段指出洛杉矶联合学区的政策不灵活，后续段落批评其问题，末段建议暂停该规则，整体态度是批评这一处理方式，对应选项A“A Faulty Approach to Homework”。选项B“A Welcomed Policy”与原文批评态度相反；选项C“Thorny Questions about Homework”只是第四段部分内容，以偏概全；选项D“Wrong Interpretations of an Educational Policy”范围过大，文章聚焦作业政策，而非一般教育政策。
