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。
