交通是 IELTS 中常见的话题。Writing Task 2 可能讨论公共交通是否应该免费、车辆进入市中心是否应收费、航空出行增长带来什么问题，以及新公路与铁路由谁出资。Speaking Part 3 常比较过去与现在的出行方式，并讨论二十年后是否仍需要汽车。
这个话题容易卡在一个形容词上：big traffic。Traffic 指车流，常搭配 heavy 或 light，而不是大或小。类似问题还有不加 a 的 public transport、具体路程用 journey 而不是 travel，以及 arrive in 而不是 arrive to。
下面整理29个搭配、面向7分目标的例句、常见错误，以及 LetsWords 的句子反馈示例。其他主题见 IELTS 话题词汇。

常见错误
1. Big traffic
In big cities there is big traffic in the morning.
In big cities the traffic is heavy in the morning. / In big cities there are traffic jams every morning.
Traffic 是不可数名词，表示车流，通常搭配 heavy 或 light。说一次具体堵塞，可以用 a traffic jam。
2. 交通表达中的冠词
More people should use a public transport and go to work by the bus.
More people should use public transport and go to work by bus.
英式英语的 public transport 不可数，不加 a。By 后的交通方式也不加冠词，如 by bus、by train、by car。使用冠词的另一种结构是 on the bus。
3. Arrive to
Many commuters arrive to the city centre late because of traffic jams.
Many commuters arrive in the city centre late because of traffic jams.
说明到达地点时，不用 to。城市或较大区域用 arrive in，建筑或具体点位用 arrive at，如 arrive at the station。也可以使用直接接宾语的 reach：reach the city centre。详见 arrive 与 reach。
4. My travel to work
My travel to work takes an hour and a half.
My journey to work takes an hour and a half. / My commute takes an hour and a half.
名词 travel 泛指出行活动，不是一段具体路程。从一地到另一地可以用 journey，日常上下班的路程则是 commute。详见 travel、trip 与 journey。
LetsWords 怎样解释这些错误
读表格时词义熟悉，造句才会暴露结构问题。一次练习可以这样进行。
复习 ease congestion 时，根据词义回忆英语表达，再写拥堵费话题：
A congestion charge can ease congestion, because fewer people will go to the centre by the car and the traffic will be less big.
反馈指出两处错误：
- by the car → by car：by 后的交通方式不加冠词，也可以更简短地说 drive into the centre；
- less big → lighter：车流用 heavy 或 light 描述，而不是大或小。
A congestion charge can ease congestion, because fewer people will drive into the centre and traffic will become lighter.
几天后换个情境重练，例如描述所在城市的口语回答，让词表搭配变成能够主动回忆并准确使用的表达。

用于 Writing Task 2
考试风格的题目：
Some people believe that the best way to reduce traffic in cities is to make public transport free. To what extent do you agree or disagree?
表达作者立场的示例段落：
Making public transport free would certainly attract some drivers, but it would not by itself ease congestion. Most people choose a car not because fares are high, but because buses and trains do not take them where they need to go quickly. If a reliable public transport system does not exist, even a zero fare will not persuade commuters to leave their cars at home. A more effective approach is to invest in public transport first, so that services run frequently and journey times are competitive with driving, and then to discourage car use with a congestion charge. This tackles both sides of the problem: driving becomes less attractive, the alternative more attractive, and heavy traffic in the centre gradually becomes the exception rather than the rule.
首句立场明确，并保持到最后：仅免费不够。之后解释原因，即出行速度与路线，再提出有具体机制的替代方案。词汇紧扣交通，重点在准确搭配，而不在生僻词，这符合 Lexical Resource 关注的用词质量。
用于 Speaking
Part 3 问题：Do you think people will use cars less in the future?
To some extent, yes. In my city, car ownership is already becoming less attractive for young people, because parking is expensive and car sharing is available almost everywhere. That said, I don’t think cars will disappear. People will probably switch to electric vehicles rather than give up driving altogether, especially in the suburbs, where buses don’t run frequently enough.
答案立即表态，提供两个理由，再用 that said 加入保留意见。这是展开的 Part 3 回答，而不只是“是”或“否”。
免费练习
- travel、trip 与 journey：泛指出行、一次旅行与一段路程；

- arrive 与 reach：哪个需要介词，为什么不是 to；
- run late：晚于计划；
- in time 与 on time：来得及与准时；
- solve a problem：解决问题及其结构；
- effective 与 efficient：取得效果与节省时间、费用。
