答案：B
答案句：The best seek to alleviate the external pressures on their pupils while equipping them better to understand and handle the world outside-at once sheltering them and broadening their horizons.
参考译文：最好的学校力求减轻学生面临的外部压力，同时让他们更好地理解和应对外部世界——既庇护他们，又开阔他们的视野。
定位线索：题干“best schools should do”→答案句“The best seek to...”；文中“alleviate the external pressures”对应选项B“Protect students from social pressures”；文中“equipping them better to understand and handle the world outside”对应选项B“enable them to face the world”。
解析：题干问作者认为最好的学校应该做什么，答案句直接描述了最好的学校的两个目标：减轻外部压力（对应选项B的“Protect students from social pressures”）和装备学生理解应对世界（对应选项B的“enable them to face the world”）。选项A“challenge and change”在文中未提及，属于无中生有；选项C“physical abilities”和选项D“ambitious”均非答案句内容，答非所问。

定位线索：题干“build community spirit”→答案句“fuel community spirit”；文中“whole-school fundraising”对应选项D“Activities involving all students on campus”；文中“proceeds pooled”体现全校参与。
解析：题干问什么有助于建立社区精神，答案句明确指出“whole-school fundraising”（全校筹款）可以“fuel community spirit”，即全校学生参与的活动能激发社区精神，对应选项D“Activities involving all students on campus”。选项A“community services”、选项B“ingenuity”、选项C“mutual understanding”均未在答案句中提及，属于无中生有。
49. What do we learn about low-income parents regarding school field trips?
- A. They want their children to participate even though they don't see much benefit.
- B. They don't want their kids to participate but find it hard to keep them from going.
- C. They don't want their kids to miss any chance to broaden their horizons despite the cost.
- D. They want their children to experience adventures but they don't want them to run risks.
答案：A
答案句：Some parents pull their children out of school because of expensive field trips. Even parents who can see that a trip is little more than a party or celebration may well feel guilt that their child is left behind.
参考译文：一些家长因为昂贵的实地考察旅行而让孩子退学。即使是那些能看出旅行不过是聚会或庆祝活动的家长，也可能因孩子被落下而感到内疚。
定位线索：题干“low-income parents”→答案句“Some parents”（指低收入家长）；文中“feel guilt that their child is left behind”对应选项A“want their children to participate even though they don't see much benefit”；文中“a trip is little more than a party or celebration”对应选项A“don't see much benefit”。
解析：答案句指出，即使家长认为旅行不过是聚会或庆祝（即看不到多大益处），他们仍会因孩子被落下而感到内疚，这说明他们内心希望孩子参加，对应选项A。选项B“don't want their kids to participate”与原文相反，家长是希望参加的；选项C“broaden their horizons”在文中未提及，且“despite the cost”不是原文重点；选项D“run risks”文中未提及，属于无中生有。
50. What is the author's expectation of schools?
- A. Bringing a community together with ingenuity.
- B. Resolving the existing discrepancies in society.
- C. Avoiding creating new gaps among students.
- D. Giving poor students preferential treatment.
答案：C
答案句：Schools cannot be expected to bring together communities single-handed. But the least we should expect is that they do not foster divisions and exclude those who are already disadvantaged.
参考译文：不能指望学校单枪匹马地团结社区。但我们至少应该期望他们不要助长分裂，不要排斥那些本已处于不利地位的人。
定位线索：题干“author's expectation of schools”→答案句“the least we should expect”；文中“do not foster divisions and exclude those who are already disadvantaged”对应选项C“Avoiding creating new gaps among students”；文中“divisions”对应选项C“gaps”。
解析：题干问作者对学校的期望，答案句明确指出“the least we should expect is that they do not foster divisions and exclude those who are already disadvantaged”，即不要制造分裂、排斥弱势学生，对应选项C“Avoiding creating new gaps among students”。选项A“bringing a community together”是作者说不能期望学校做到的，与题干不符；选项B“resolving the existing discrepancies”程度过重，作者只要求不加剧差距；选项D“preferential treatment”文中未提及，属于无中生有。
