答
我看没错
答
就你个人的句子而言,我同意"喜欢二一"的看法;就句子的意思而言,我建议你用"socratesli"给你修改后的句子．
答
我的修改是
An accident happens unexpectedly and unintentionally AND without a purpose.
以前的句子转折有点问题，以你给的原句看来；而且没必要非要用个动词，累赘的东西完全可以改掉。
答
An accident happens unexpectedly and unintentionally, but doesn’t happen on purpose.
答
An accident happens unexpectedly and unintentionally without any purpose.
你的句子说不出哪里不对,但是感觉就是不舒服,你看如上改一下如何?
答
我觉得后面那句是多余的，而且BUT是连词连接前后两个句子所以后面的应该是完整的句子but it doesn’t happen with a purpose.
