为什么要读这篇？
你的学生写”教育成本高”时，是否永远只有 expensive 和 cost a lot of money？
今天这篇FT文章讨论的是英国私立学校费用不断上涨的现象——但其语言远不止说”贵”。作者用了一组精准的财务类动词和因果结构来描述”成本上涨如何挤压家庭选择空间”。这种”先说现象 → 再分析原因 → 然后给出数据支撑 → 最后谈影响”的写作结构，正是中高考和雅思议论文最需要的逻辑骨架。
我们从这篇FT报道中提取5个教育/经济/社会类议论文通用的高级表达，让你的作文在”成本与选择”类话题中不再贫瘠。
FT原文精选
Privately-funded schools have many advantages, mostly born of the extra money they can spend per child.
However…funding that choice is becoming harder. Rising house prices mean mortgage payments are taking a bigger proportion of household income, leaving less to cover school fees.
Eton, for example, will set you back £14,698 a term (plus a £400 registration fee and £3,200 “acceptance fee”).
Schools with good reputations and facilities are in high demand among rich overseas families, so they can ratchet up fees, knowing it will not deter many “customers”.
中文对照： 私立学校有很多优势，主要源于它们在每个孩子身上能花更多钱。但为这种选择筹措资金正变得更加困难。不断上涨的房价意味着房贷占了家庭收入的更大比例，留给学费的钱就少了。伊顿公学每学期将花掉你1.47万英镑。声誉好的学校可以提高学费，因为他们知道这不会吓跑客户。
5个考场高分表达
1. born of 源于 / 产生于
原文出处： “Privately-funded schools have many advantages, mostly born of the extra money they can spend per child.”
为什么好： 写”原因”时，大部分学生只会用 because。born of 是一个优雅的书面语表达，意思是”由……产生的/源于……”，它自带一种因果关系，同时比 result from 更具画面感——仿佛某种结果是”出生”于某个源头。用在议论文中解释某种现象的根本原因，非常出彩。
| 学生写法 | 升级写法 |
|---|---|
| The problem is because of the lack of funding. | The crisis is born of years of underinvestment in public education. |
| Many students feel stressed because of exam pressure. | The rising anxiety among teenagers is born of an exam-driven education system. |
例句： The growing resistance to smartphones in schools is born of concerns over declining attention spans and social isolation among students.
2. set someone back 花掉某人（多少钱）
原文出处： “Eton, for example, will set you back £14,698 a term…”
为什么好： 99%的学生写”某物花了多少钱”时只会写 cost。set someone back 是一个地道、生动且略带夸张感的表达，非常适合在议论文中举例说明费用之高。它比 cost 更有语言趣味，比 charge 更口语化但又不失正式感。
| 学生写法 | 升级写法 |
|---|---|
| A year of private school costs £30,000. | A year of private school will set you back £30,000. |
| The new laptop cost me ¥8,000. | The latest model set me back nearly ¥8,000. |
例句： A month of summer camp can set parents back as much as ¥20,000, not including airfare and pocket money.
3. ratchet up 逐步提高 / 步步攀升
原文出处： “…so they can ratchet up fees, knowing it will not deter many ‘customers’.”
为什么好： 写”上涨”时，大多数学生只会用 increase 和 go up。ratchet up 是一个有画面感的动词短语——就像棘轮（ratchet）只能单向转动不能后退一样，这个词暗示”只会越来越贵，不会降下来”。用在描述费用、压力、紧张局势的持续上升时非常有力量。
| 学生写法 | 升级写法 |
|---|---|
| The cost of education keeps increasing. | Schools continue to ratchet up tuition fees year after year. |
| Stress among students is going up. | Exam pressure ratchets up as the gaokao approaches. |
例句: Competition among top universities continues to ratchet up, with acceptance rates dropping to record lows.
4. leaving less to cover 剩下的钱不足以覆盖…… / 留给……的钱更少了
原文出处： “Rising house prices mean mortgage payments are taking a bigger proportion of household income, leaving less to cover school fees.”
为什么好： 这个结构由三部分组成：原因 → 中间变量 → 结果。leaving less to cover X 是因果链条的收尾表达。它比简单的 so people have less money for X 更正式、更书面，适合在议论文中做”连锁反应”的描述。
| 学生写法 | 升级写法 |
|---|---|
| People spend more on housing, so they have less for education. | Rising rents leave less to cover children’s extracurricular activities. |
| Because of tuition fees, families cannot save money. | High tuition fees leave less to cover daily living expenses. |
例句： The rising cost of textbooks and accommodation leaves less to cover students’ social and mental health needs, which schools often overlook.
5. funding that choice is becoming harder 为这个选择筹措资金越来越难
原文出处： “…funding that choice is becoming harder.”
为什么好： 这句话看似简单，但其中的抽象名词 + choice + 动词结构非常值得模仿。大多数学生会写 people have less money for this，而FT的写法把”选择”（choice）作为主语中心词——funding that choice。这体现了英语写作中用抽象概念做主语的高级思维。
这个句型可以灵活替换不同的名词：funding that project / sustaining that lifestyle / continuing that tradition / justifying that decision。
| 学生写法 | 升级写法 |
|---|---|
| It’s hard for families to pay for private education. | For many families, funding that choice is becoming harder each year. |
| People cannot afford this lifestyle anymore. | Sustaining that lifestyle is becoming harder as inflation rises. |
例句： With university fees approaching ¥30,000 a year in some cities, justifying that expense is becoming harder for middle-class families.
写作示范：教育成本类议论文的”四步论证法”
这篇FT文章最值得学习的不仅是单个表达，更是其论证结构。当你写”某件事（教育/医疗/住房）成本越来越高”时，可以套用这个结构：
| 步骤 | 功能 | 例句 |
|---|---|---|
| ① 优点 | 先承认合理性 | Private education has clear advantages, born of better resources. |
| ② 转折 | 但问题出现了 | However, funding that choice is becoming harder. |
| ③ 数据 | 用具体数字说明 | A top-tier school can set a family back £15,000 per term. |
| ④ 推论 | 连锁后果 | As fees ratchet up, rising costs leave less to cover other essentials. |
考场应用： 如果作文题是”Should parents spend heavily on children’s education?”，你可以在主体段这样展开：
“After-school tutoring has clear advantages, mostly born of the individualised attention it offers. However, funding that choice is becoming harder for many families. A year of intensive English classes can set a family back ¥30,000. As competition for university places continues to ratchet up, the financial burden leaves less to cover children’s hobbies and rest time.”
