外语自言自语｜场景：清晨，我在公交站台上等车，试着把眼前这一幕用英语说得一字不差｜语言：English（英语为主）

陪练对象：小优（契苾小优，古凉州今武威）

外语独白

Transport. This morning I stood at the bus stop and realised I could describe the whole scene in Chinese in five seconds, and in English I would still be fumbling with prepositions. (今天聚焦维是准确，所以这篇我不图快，图准)

So let me be precise. I get on a bus, a train, a plane. I get in a car or a taxi. 差一个介词，画面就全变了：前面是踩上去，后面是钻进去。And when I leave, I get off the bus but I get out of the car. 我从前一律说 get out of the bus，听着像从公交车里爬出来，很怪。

The journey has its own vocabulary too. A commute is the regular trip between home and work, and the word carries a small sigh inside it. (commute 那点「天天如此」的疲，中文的「通勤」传不出来) I used to say take the subway, which is American; in London it is the Tube, and across most of Europe the same tunnel is the metro. One hole in the ground, three names.

Then the numbers, where I keep slipping. If I say a two-hour commute, the hour stays singular, no s. 中文说两小时通勤，加不加 s 是英文自己的规矩，漏了就是错。That is what accuracy means to me today: not big words, but the small joints that hold a sentence together. Get the joint wrong and the whole thing rattles.

语法笔记

Today's four traps are all accuracy traps, the kind that do not stop you talking but quietly mark you down.

The first is the preposition after arrive. We arrive in a city or a country, and at a station, an airport, a stop. 中文只说「到了」，英文非要问一句：你到的是大范围还是小地点。I arrived in Urumqi, I arrived at the airport. 说 I arrived the airport 就丢了落点。

The second is which tense carries the habit. I have been commuting for six years means it is still going on, and it is the tense I actually need for my own life. I commuted for six years means that chapter closed. 同一句中文「我通勤了六年」，英文得先交代这六年结束了没有。

The third is the compound adjective before a noun. A three-hour journey, a ten-minute walk, a two-day trip. The unit stays singular because it is doing the job of an adjective. 只要它跑去当形容词，复数就得让位。这是写作里最容易掉的分，尤其 Task 1 描述时长。

The fourth is take versus get on. We take the line, the bus, the lift; we get on the vehicle itself. I take the number 4 bus and get on at the second stop. 一个是选哪条线，一个是踩上哪辆车，两件事。

中式英语易错

❌ 中式英语 by foot

✅ 地道表达 on foot

步行是 on foot，介词错了就没了

❌ 中式英语 I go to work by my car

✅ 地道表达 I drive to work

by + 交通工具不加冠词和物主代词

❌ 中式英语 I arrived the station

✅ 地道表达 I arrived at the station

arrive 是不及物，后面要 at / in

❌ 中式英语 The traffic is very crowded

✅ 地道表达 The traffic is heavy

crowded 形容人和地方，车流用 heavy / bad

❌ 中式英语 The traffic jam is serious

✅ 地道表达 I'm stuck in a bad traffic jam

jam 本身够重，不必再加 serious

❌ 中式英语 I very like travelling

✅ 地道表达 I really enjoy travelling

very 不能修饰 like

❌ 中式英语 I have went to Xi'an

✅ 地道表达 I have gone to Xi'an

完成时后面是过去分词，went 是过去式

❌ 中式英语 I waited the bus for ten minutes

✅ 地道表达 I waited for the bus

wait 后面必须跟 for

❌ 中式英语 I drive very fast speed

✅ 地道表达 I drive at high speed

speed 前面是 at，不是 very

❌ 中式英语 There were many traffics on the road

✅ 地道表达 There was heavy traffic

traffic 不可数，永远不加 s

同义替换

• 拥堵 crowded → congested / gridlocked / packed（gridlocked 专指整条路卡死，画面最强）

• 出行 travel → journey / trip / commute / voyage（journey 重过程，trip 重来回，voyage 走海路）

• 出发 go → set off / head off / depart（set off 最口语，depart 最正式，播报里用）

反过来，中文直译最容易翻车的是「坐地铁去上班」说成 sit the subway to work。地道说法是 take the metro to work 或 commute by metro。sit 是你坐在那儿，选择哪条线要用 take。

今日句型

• The reason this matters is that…（把重点落在解释上，写作与 Part 3 都好用）：The reason door-to-door time matters is that commuters count every minute, not every kilometre.

• What I got wrong was not the word but the preposition（今天准确维的自嘲句，也可以改成任何主语的版本）：What I got wrong was not the vocabulary but the small joints between words.

今日表达 TOP3

1. get stuck in traffic（堵在路上）：I got stuck in traffic and missed the opening. 比 there was a traffic jam 有代入感，因为主语是我。

2. within walking distance（步行可达）：The museum is within walking distance of the old town. 一个短语就把距离感、便利感一起说清。

3. a two-hour commute（两小时通勤）：A two-hour commute quietly eats a working day every week. 注意 hour 不加 s，这是今天准确维的头号考点。

一词多义 · 小心熟词生义

• coach: today's sense is a long-distance bus, as in We took a coach across the province. The far more common sense is a trainer, as in a basketball coach. 同一个词，一个载人，一个教人。

• fare: today's sense is the money you pay to ride, as in a bus fare has gone up again. As a verb it means how you got on, as in How did you fare in the interview? 作动词时不谈钱，只谈结果。

• terminal: today's sense is where a route begins or ends, as in the airport terminal. As an adjective it means final and irreversible, as in a terminal illness, and in computing it is the screen you type into.

• jam: today's sense is a line of vehicles that cannot move, as in a traffic jam on the ring road. The older sense is the fruit you spread on bread, as in strawberry jam.

• traffic: today's sense is vehicles moving along a road. As a verb it carries a darker meaning, to trade illegally, as in traffic in stolen goods. 一个走车，一个走货。

• fine: today's sense is money paid for breaking a rule, as in a parking fine. The much more common sense is good or delicate, as in a fine distinction between two ideas.

• park: today's sense is to leave a vehicle somewhere, as in I parked outside the station. The older sense is the green space itself, and in British speech park yourself simply means to sit down.

• drive: today's sense is to operate a car. It also names the energy that pushes a person, as in She has real drive, and in computing it is the disk drive.

• ride: today's sense is a trip in a vehicle, as in a long ride home. In everyday speech give me a ride means give me a lift, with no horse anywhere near it.

注意：coach, terminal, traffic and fine are the four to watch, because each one changes meaning completely the moment you leave the road. Note too that fare as a verb has nothing to do with money, and traffic as a verb has nothing to do with cars.

学科短文

Transport is where geography, economics and public health collide on the same strip of asphalt. Two numbers frame the problem. The first is safety: the WHO's 2023 status report counted about 1.19 million road traffic deaths in a single year, and roughly nine in ten of them in low- and middle-income countries, which together hold only about six in ten of the world's vehicles. Road injury is the leading cause of death for people aged 5 to 29. The second is volume: the global motor-vehicle fleet is projected to double by 2030.

Conventional wisdom says the cure is more road. Economics keeps disagreeing. Duranton and Turner's 2011 study, "The Fundamental Law of Road Congestion", found that newly built capacity fills up almost immediately, because faster roads pull trips out of other modes and lengthen the ones already being made. This is induced demand, and it explains why cities that widen motorways tend to meet the same jams a few years later at a larger scale. What does shift behaviour is price and alternative. Singapore introduced the world's first congestion pricing scheme in 1975; London followed in 2003 and cut central traffic volume by roughly a fifth; Stockholm, after a 2006 trial, made its charge permanent in 2007.

Then there is the quiet structural shift. The global electric car stock went from about 17,000 in 2010 to 7.2 million in 2019, and 47 per cent of that fleet sat in China. That is still under one per cent of the world's cars, so the headline "electric transition" describes a small, fast-moving tip of a very large fleet.

重点词：asphalt（沥青，词源可追到希腊语 asphaltos，黏结物）／ induced demand（诱导需求）／ congestion pricing（拥堵定价）／ fleet（车队，此处指全部在册车辆）／ short-haul（短途）。词源小知识：transport 来自拉丁语 trans（穿过）+ portare（搬运），本义就是「把东西搬过去」；vehicle 来自 vehere（拉、载），与 vector（带菌者、向量）同出一源，一个是载人，一个是载方向。

数据纵深 · 两张图连起来读

The first chart is a horizontal bar showing where the world's road deaths happen, region by region. South-East Asia carries 28 per cent and the Western Pacific 25, so half the world's road deaths sit in two regions. Europe, with the safest roads and the strictest vehicle standards, accounts for 5 per cent, roughly a sixth of South-East Asia's share.

But the share is not the risk. A region can post a big share simply because it holds a big population. 这里最容易看错：占比说的是「死了多少人」，不是「多危险」。The correct measure of danger is the rate per 100,000 people, and on that measure the ranking moves, which is exactly the kind of distinction an examiner wants in an overview.

The second chart is a donut: of the 7.2 million electric cars on the road in 2019, 3.4 million were in China, 1.7 million in Europe, 1.5 million in the United States, and 0.6 million everywhere else. China alone held 47 per cent. 一个国家的份额接近一半，另外两个加起来四成半，剩下的整个世界只有百分之八。

Set the two charts side by side and the contrast is the interesting part. The safety burden is concentrated in places with few vehicles; the electric fleet is concentrated in places with many. The countries that will add the most cars in the next decade are the ones with the least capacity to absorb them safely. That sentence is not a Task 1 sentence, because Task 1 may not explain causes. But it is exactly the kind of observation Task 2 rewards.

词根串联复习

Every transport word today is a Latin or Old English root doing a modern job.

• portare, to carry: transport, portable, export, report (carry news back). Transport is quite literally carrying across.

• vehere / vectus, to carry, to ride: vehicle, vector, convection, vehement (originally "carried along"). 今天那个熟词生义 vehicle，根就在这儿。

• ire / iter, to go, a journey: itinerary, exit (go out), transit, ambition (originally "going around" canvassing for votes). 一份 itinerary 就是「一趟一趟地走」。

• jungere, to join: junction, join, conjunction, adjacent (lying next to). 路口就是把两条路接上。

• ped / pod, foot: pedestrian, pedal, pedestal, tripod (three-footed). 脚这个词根，撑起了半个出行词汇表。

• terminus, boundary, end: terminal, terminate, determine (to fix the end). 终点站就是一条线被钉住的界石。

Two more to carry away: congestion shares its root with digest and gesture, all from gerere, to carry; and fare is not Latin at all, it comes from Old English faran, to journey, which is why fare also means "how you get on".

⏳ ⏳ 艾宾浩斯复习

Today's topic is transport, so it is a good day to pull old words back through it. Spaced repetition works best as transfer, not as a list.

• 2026-09-24, work. commute returns with a different face: it belongs to both topics, and today the emphasis is on the journey rather than the job. a two-hour commute is also the exact compound-adjective trap from today's grammar note.

• 2026-09-26, maths. distribution and outlier are doing visible work again. The road-death shares are a distribution with one clear outlier at the low end, Europe at 5 per cent, and the electric-car donut is a share of a whole.

• 2026-09-28, health. resilience transfers into infrastructure: a transport network's resilience is measured by how it behaves when one link fails, not by its average speed on a good day.

• 2026-09-25, education. shape fits the data: road design shapes behaviour more reliably than road signs do.

• 2026-09-27, health add-on. sedentary reappears from the other side. A city built only for cars makes everyone sedentary by default, which is how transport policy turns into public health policy.

旧词不孤学，勾进新场景才算真记住。

Part 2 题卡 · 描述一次出行

交通类 Part 2 常考「描述一次你记得很清楚的旅行／一种你喜欢的出行方式／一次延误」。按四段框架走，两分钟刚好。

Cue card：Describe a journey you remember well. You should say where you went, how you travelled, what happened during the journey, and explain why you still remember it.

四段框架

发音 / 连读提示

Four words today, and their stress does not sit in the same place, which is exactly why they trip people up.

• route: British speakers usually say /ruːt/, American speakers usually /raʊt/, and both are standard. Pick one and stay with it inside a single conversation. 同一个句子里别来回换，换一次就露怯。

• congestion: /kənˈdʒestʃən/, with the stress on jes and everything in front of it flattened. Chinese speakers tend to drag the stress forward and say something like "康杰斯申", which breaks the word in half.

• itinerary: /aɪˈtɪnərəri/, five syllables with the stress on tin and three of the five reduced to weak vowels. It is the longest word today, and slowing down is what makes it accurate.

• vehicle: /ˈviːɪkl/ in British English, /ˈviːhɪkl/ in American, both accepted. The h is barely heard in the British form, so do not over-articulate it.

Linking note: get on it runs together as /ɡeˈtɒnɪt/, the final t of get sliding straight into on. In an hour and a half the h of hour is silent, so it reads /ən ˈaʊər ənd ə hɑːf/. The rule underneath is simple: a preposition always leans on the verb in front of it.

多语种句尾

Most of today's words came into English through Latin, and they fan out across the Romance languages in recognisable shapes. Transport stays transport in French, transporte in Spanish, trasporto in Italian; pedestrian becomes piéton, peatón, pedone, all still standing on the same Latin foot. Language is one net with different knots.

One thread worth pulling further: the Spanish viaje and the French voyage both descend from Latin viaticum, "provisions for a journey", which itself comes from via, a road. 也就是说，「旅行」这个词最早的意思是「上路前带的那份干粮」。English kept via for the road itself and borrowed voyage for the trip, so the same root now names both the way and the going.

An English line to carry away: Accuracy on the road starts with the preposition, not the engine.

写作联动 · 看图写作

今天周二，按轮换做「数据图表口述」。两张图：一张横向条形图看全球道路死亡的区域分布，一张环形图看 2019 年全球电动车保有量的地区构成。

Task 1 写作任务

图一：The bar chart shows the share of global road traffic deaths by WHO region. Summarise the information by selecting and reporting the main features, and make comparisons where relevant. Write at least 150 words in about 20 minutes.

图二：The chart shows the regional composition of the global electric car stock in 2019. Summarise the information by selecting and reporting the main features, and make comparisons where relevant. Write at least 150 words in about 20 minutes.

两图都必须写 overview 与 key features，按图型做分组比较。

描述句型（条形图与饼图句型包合用）

• South-East Asia accounted for the largest share at 28 per cent, closely followed by the Western Pacific at 25 per cent.

• Together, the two leading regions accounted for just over half of all road traffic deaths.

• By contrast, Europe recorded the smallest share, at only 5 per cent.

• China held 47 per cent of the global electric car stock, more than the next two regions combined.

• The remaining regions together made up less than one tenth of the total.

• Overall, the distribution was heavily skewed towards a single category, with a long tail behind it.

范文要点

1. Overview（图一）：死亡份额高度集中，前两个区域合计 53%，欧洲仅 5%，高低之差超过五倍。

2. 分组：可按「高份额组（东南亚 28、西太 25）」与「低份额组（美洲 12、东地中海 11、欧洲 5）」两组来写，中间不再细分，这是条形图的得分写法。

3. Overview（图二）：环形图讲的是构成，重点在中国一家接近一半（47.2%），欧洲与美国合计 44.4%，其余全世界 8.3%。

4. 可比性提示：图一是「占全球死亡人数的比例」，不是死亡率，描述时不要写成 death rate；图二是保有量（stock），不是当年销量，两个概念别混。

统计旁注（条形图与环形图的统计内核）

条形图看的是「类别之间的大小与排序」，柱子之间留空，表示类别彼此独立。这一组按降序排好后，头部两个类别明显抬起来，尾部三个挤在 5% 到 12% 的窄带里，写的时候报「排序 + 头部集中 + 尾部密集」三点就够了。

环形图看的是「一个整体怎么被切开」，所有扇形必须加满 100%。它的经典陷阱是「份额大不等于风险大」：东南亚占死亡人数的 28%，但那是绝对量的份额，不是每十万人的死亡率。把 share 当 rate 写，是这类图上最常见的失分点，也是今天准确维最该盯紧的地方。

✍️ ✍️ 写作联动 · Task 2 论点库

交通是雅思大作文的高频区。四个常见题，每个给一条立场句、一组可引数据、几个关键词和一句让步。

议题一：该不该收拥堵费

• 立场句：Congestion charging works because it prices a scarce resource, but it must be paired with alternatives or it simply taxes the poor.

• 数据：伦敦 2003 年开征后中心区车流约降两成；新加坡 1975 年就落地，是全球最早的拥堵定价方案。

• 关键词：road pricing, demand management, regressive effect, public transport revenue

• 让步：Admittedly, a flat charge falls hardest on those who can least afford to change their travel habits.

议题二：公共交通该不该免费

• 立场句：Fare-free transit increases ridership, but the money may buy more capacity elsewhere than it buys at the ticket machine.

• 数据：全球每年约 119 万人死于道路交通事故，其中约九成在中低收入国家，交通安全与出行方式直接相关。

• 关键词：subsidy, modal shift, capacity, cost per journey

• 让步：Free fares do not by themselves fix a network that is slow, sparse or unsafe.

议题三：电动车能不能解决交通问题

• 立场句：Electric cars clean the exhaust pipe, not the traffic jam; they change emissions, not volume.

• 数据：2019 年全球电动车保有量 720 万辆，仍不到世界汽车总量的百分之一，而全球机动车总量预计到 2030 年翻倍。

• 关键词：charging infrastructure, grid capacity, induced demand, life-cycle emissions

• 让步：Battery costs are falling fast, and the transition may accelerate faster than these figures suggest.

议题四：自行车道值不值得修

• 立场句：Protected cycle lanes are the cheapest way to move people short distances, and they only work when they are physically separated.

• 数据：Duranton 与 Turner 2011 年的研究表明，单纯增加道路容量会被新增出行迅速填满；改变结构比增加面积更有效。

• 关键词：protected lane, last mile, road space reallocation, safety in numbers

• 让步：In cities with long distances and harsh winters, cycling can only ever carry a modest share.

论证提醒：图表数据只能当 evidence，不能当 argument。Task 2 里引一个数字，后面必须跟一句解释它为什么支持你的观点，否则数字白摆。

交通小史

The way we move was rebuilt in about a hundred and fifty years, and the dates are unusually sharp.

1825: the Stockton and Darlington Railway opened in northern England, the first public railway to use steam locomotives, and the beginning of scheduled mechanical transport. 1863: London's Metropolitan Railway opened, the world's first underground railway, built because the streets above could no longer carry the traffic. 1886: Karl Benz patented the Motorwagen, the first practical automobile, and within a generation the street had a new master.

1908: Ford put the Model T into production, and the car stopped being a rich man's machine. 1956: the United States passed the Federal Aid Highway Act, which built the Interstate system, and the shape of the modern city followed the exits. 1964: Japan opened the Tōkaidō Shinkansen, the first high-speed railway, and proved that a train could beat a plane on the routes that matter. 1969: the Boeing 747 flew for the first time and made long-haul travel ordinary.

Then the century turned. By 2019 the global electric car stock had reached 7.2 million, from a standing start of about 17,000 in 2010. 一百五十年，从蒸汽到电动，速度变了，拥堵没变。

None of which belongs in a Task 1 answer, which must stay purely descriptive. But in Task 2, one accurate date outworks three adjectives.

Looking from 古凉州今武威, transport was never about the road alone. It was about where the road decided to stop. 《晋书·张轨传》describes 姑臧卧龙城 in numbers a surveyor would respect: 南北七里，东西三里, seven li north to south and three east to west, its ground shaped like a dragon. 一座城的形状，本身就是交通的手笔：路怎么进来，城就怎么长。

That geometry was not decoration. 姑臧 sat astride the Hexi corridor, and the goods that made the town rich moved through it in both directions. A Sogdian letter written at 姑臧 in 312, one of the oldest surviving Sogdian documents, tells of a merchant caravan leader writing home to Samarkand about goods dispatched inland. 一封从凉州寄往撒马尔罕的信，比任何形容词都能说明这座城当年在路上的分量。凉州（武威）在历史上，曾是粟特商团的大本营。粟特人就是中亚的商人。公元313年前后，他们就以姑臧城为基地做生意了。东边到洛阳，西边回老家撒马尔干，全在他们商路上。

And the city fed its travellers from the ground around it. 凉州畜牧天下饶, from《汉书·地理志》, meant horses and herds were the real engine of movement: a posting station empire runs on livestock. While 凉州绯色天下最, from《魏书·尉聿传》, tells of the dyed silk that travelled the other way, west and east, on the same road.

One person from here travelled farthest. 李自标, a 凉州 man born in 1760, went to study in Naples as a boy and by 1793 was serving as an interpreter on the Macartney mission to the Qing court. 一个凉州少年，走了大半年才到的地方，最后成了两种语言之间的桥。If transport is about getting somewhere, he is the local proof that the somewhere can be very far away.

Today at the foot of 凉州莲花山（姑臧紫山）the road still runs past the same slope, and people still travel it for the same reasons. 这座山，老书上写它姑臧紫山，今人叫它凉州莲花山，路还是那条路。出门这件事，凉州人做了两千年，做法变了，方向没变。
