关于“traffic”与be动词的搭配,需根据其词性和使用语境来选择:

作为名词时

- 单数主语:

- 现在时: is

- 过去时: was/were

- 示例:

- The traffic in the city is very heavy today.

- Yesterday, there was a major accident on the highway.

- 复数主语:

- 现在时: are

- 过去时: were

- 示例:

- The traffic lights are malfunctioning.

- Last night, there were several breakdowns on the road.

作为动词(及物/不及物)时

- 及物动词(如"traffic away"):

- 现在时: traffic+ 宾语

- 过去时: trafficked

- 示例:

- The company's profits were traffic away by the new policy.

- 不及物动词(如"traffic lights"):

- 现在时: traffic

- 过去时: trafficked

- 示例:

- The traffic in the downtown area is always busy.

补充说明

若需强调"交通流量"这一整体概念,常用 there is/are结构:

现在时:

- There is heavy traffic on the main road.

过去时:

- There were jams due to the snowstorm.

注意避免混淆:

不可数名词(如"traffic")与可数名词复数在be动词选择上无本质区别,完全取决于主语是单数还是复数。
