这几个英语句子有什么错误吗?dangerous is around us 危险就在我们身边 They across the road when the traffic light is in red 他们在红灯的时候过马路Let“s us raise the awareness 让我们提高意识

1. Danger is around us.
Dangerous是形容词，不能单独做主语。
2. They went across the road when the traffic light was red.
across只是个副词，不能单独当谓语动词用的。
3. Let's strengthen the awareness.
raise只是中文理解的提高，其实是要加强的意思，用strengthen更合适。

1.dangerous is around us
dangerous 应为 Danger
2.They across the road when the traffic light is in red
across 应为cross in red 应为 red
3.Let“s us raise the awareness
Let“s us应为Let‘s (Let's=Let us )

1 错误,dangerous是形容词,不能做主语.
改为 The danger is around us
2 错误,across 是副词,不能做谓语
改为 They cross the road when the traffic light is in red
3 错误,重复Let“s已经有us了
改为 Let“s raise the awareness

dangerous 是形容词，应改为名词danger
across是介词，应改为动词 cross
let's=let us，所以多一个us,去掉
