翻译：我们决定这种事情绝不允许再发生

We decided that it would not be allowed to happen again

We decide that things aren't allowed to happen again

我们决定这种事情绝不允许再发生

这是一个被动语态

乐意为你解答^_^

按意思来翻

This accident won't be happened again, we promise

这次事件不会再次发生,我们保证
在英语里,想要表达的事物总是放在最前面,这句话一般不能以WE来做主语,并且英语中一般不用THING这个单词,因为意思太广泛

We have made a decision that we will not allow anything to happen like this.

It's our decision that we won't let things like this happen again.

we are sure that the thing like this will never happen again.
