读《金融时报》学英文写作：论证方法——比较要公平：占比、人均与增量

学生写对比，最顺手的句式是：China has more people than Japan. Our school spends more money on sports than on art. 语法没错，论证却等于零——因为”总量大”的那一方本来就赢，这种比较不需要论证，只需要体量。

真正的高手不这么比：他们先把两个不可比的量换算成可比的量，再让读者自己从数字里读出结论。今天我们从《金融时报》一篇关于欧洲5G建设落后的报道里，学四种让比较”站得住”的论证手法。这篇报道的精妙之处在于：同一个事实（欧洲落后），作者换了四次分母，每一次都让结论更硬。

FT原文

The number of Europeans able to connect to a 5G network was 24 per cent at the end of September compared to 13 per cent at the end of 2019, according to new research.

However, that pales in comparison with the 76 per cent of Americans able to connect to 5G and even higher rates in some parts of Asia, such as South Korea where it is 93 per cent, according to a report by telecoms trade body ETNO and research company Analysys Mason.

… the pace of investment by the sector is rising, with almost €52bn spent in 2019 compared to €48.6bn the previous year.

However, the average investment per capita in new networks remains lower than in other regions at €94.8 compared to €147.9 in the US and €233 in Japan.

However, monthly average mobile revenue per user in the region was less than €15 compared to €23.7 in the South Korea and €28.1 in Japan and €36.9 in the US, according to the report.

中文对照

新研究表明，去年9月底，能够连接5G网络的欧洲人比例为24%，相比之下2019年底的数据是13%。

然而，根据电信行业组织”欧洲电信网络运营商协会”(ETNO)和研究公司Analysys Mason的一份报告，欧洲远比不上美国和亚洲一些地区——可以连接5G的美国人比例为76%，亚洲一些地区的比例甚至更高，例如韩国达到93%。

……该行业正在加快投资步伐，2019年投资接近520亿欧元，相比之下2018年投资额为486亿欧元。

然而，欧洲在新网络上的人均投资仍低于其他地区，为94.8欧元，而美国和日本则分别为147.9欧元和233欧元。

然而，该报告显示，按月度计算，欧洲的移动”每用户平均收入”(ARPU)不到15欧元，而韩国为23.7欧元，日本为28.1欧元，美国为36.9欧元。

手法一：占比对比法——用比例，不用”多和少”

看这句：

The number of Europeans able to connect to a 5G network was 24 per cent at the end of September … However, that pales in comparison with the 76 per cent of Americans … such as South Korea where it is 93 per cent.

学生写”欧洲落后”，多半是 Fewer Europeans use 5G than Americans. 读者第一反应是反驳：欧洲人口本来就少。FT 换掉了主语——不比”多少人”，比”能连上5G的人占比”。24% 对 76% 对 93%，分母一致，体量差异被消掉，落后立刻变成硬事实。

❌ 学生初版

Fewer Europeans use 5G than Americans do.

✅ 升级版

Only 24 per cent of Europeans could connect to a 5G network, compared with 76 per cent of Americans and 93 per cent of South Koreans.

💡 效果

百分比把”多与少”变成”覆盖率”，比较对象从国家体量换成了同一口径下的比例——结论不再需要说服，读数字就成立。

模板

The share of [主体A] doing [X] was [N] per cent, compared with [M] per cent in [B] and [P] per cent in [C].

例句

The share of students in our school who exercise every day was only 31 per cent, compared with 58 per cent in the neighbouring school.

手法二：人均归一化法——总量不可比时，换分母

看这句：

However, the average investment per capita in new networks remains lower than in other regions at €94.8 compared to €147.9 in the US and €233 in Japan.

“欧洲投资少”这句话本身不成立：欧洲国家多、市场碎，总投入并不必然低。FT 用了一个字改变一切——per capita（人均）。分母换成人，投入能力立刻可比：94.8、147.9、233，差距一眼可见。学生作文里最缺的就是这个动作：知道自己在比”不可比的东西”，却仍然拿总量硬比。

❌ 学生初版

Europe invests less money in 5G networks than Japan.

✅ 升级版

Average investment per capita in new networks was only €94.8, compared with €147.9 in the US and €233 in Japan.

💡 效果

per capita / per user 把”总量之争”变成”单位能力之争”。凡是人数、面积、时间不同的两个对象，都可以用这个词救回可比性。

模板

[总量] is not a fair comparison, but [指标] per capita was [N], compared with [M] and [P].

例句

Our city does not spend less on libraries than the capital, but spending per capita was only 40 yuan, compared with 120 yuan there.

手法三：承认进步，再指出落后——增量不等于追平

看这句：

… the pace of investment by the sector is rising, with almost €52bn spent in 2019 compared to €48.6bn the previous year. However, the average investment per capita in new networks remains lower than in other regions.

如果只写”欧洲投资创新高”，读者会以为问题解决了。FT 先说利好（投资从486亿欧元涨到近520亿），再用一个 However 指出相对位置（人均仍低）。这叫承认进步、指出差距：数据是真的，但坐标更真。学生写对比常犯的错是”只挑对自己有利的那一头”——要么只说进步，要么只说落后。

❌ 学生初版

Europe is investing more money, so its networks will catch up soon.

✅ 升级版

Investment is rising, with almost €52bn spent in 2019 compared to €48.6bn the previous year. However, investment per capita remains far lower than in the US and Japan.

💡 效果

先给利好、再给坐标，读者既看到努力也看到位置，“仍然落后”的结论才有厚度——这也是让步意识在数据层面的写法。

模板

[指标] is rising, with [N] in [时间] compared to [M] before. However, [相对指标] remains lower than [参照系].

例句

Our school is spending more on books, with 20,000 yuan last year compared with 15,000 the year before. However, spending per student remains lower than the district average.

手法四：交代比较的来源——让对比不是”我觉得”

看这句：

… according to new research. / … according to a report by telecoms trade body ETNO and research company Analysys Mason.

注意这篇报道里出现了三次 according to：数据不是作者的判断，而是有出处的比较。学生写对比时最爱写 “It is obvious that A is better than B”，读者只能选择信或不信；而一旦写成 “According to a report by X, …”，比较就变成了可核查的陈述。比较越硬，出处越要交代。

❌ 学生初版

It is obvious that European networks are much worse than American ones.

✅ 升级版

According to a report by ETNO and Analysys Mason, only 24 per cent of Europeans could connect to 5G, against 76 per cent of Americans.

💡 效果

把”我认为”换成”报告显示”，论证的责任从作者转移到了数据源，读者反驳的成本立刻升高。

模板

According to [机构] / [研究], [主体A] [指标] was [N], compared with [M] in [B].

例句

According to a survey by the city health bureau, only 31 per cent of local teenagers exercise daily, compared with 58 per cent in 2015.

写作建议

这四种手法的共同点是：比较的本质不是”谁更大”，而是”分母是否一致”。下次写对比类作文（城市 vs 乡村、线上 vs 线下、本国 vs 外国），先别急着下结论，问自己四句话——我比的是比例还是总量？总量不可比时我换分母了吗？我敢不敢同时写出进步和差距？我的比较有没有交代来源？前两问解决”公平”，后两问解决”可信”。做到这四步，你的对比才叫论证，而不叫站队。
