Answer

对不起，上面的 Conj S1 V1, S1 V1 应该要改成 Conj S1 V1, S2 V2。

Answer

您好！
您提的问题牵涉到「分词构句」，是从这样的句型简化来的：Conj S1 V1, S1 V1.

简单说，首先可以将 Conj (conjunction) 去掉，接着如果 S1 和 S2 相同的话，S1 又可去掉，而 V1 若是主动就改成 Ving (完成式改成 Having Vpp)，是被动就改成 (Being) Vpp。

您提的问题应该是从这句来的：Because it is raining outside, I can't go out for sports. (您提的 rainning 不小心多拼了一个 n。)
It raining outside, I can't go out for sports → 正 (Because 拿掉，动词 rain 是主动加 ing (进行式并无妨)，前半句和後半句的主词不同所以 it 要留着)
Raining outside, I can't go out for sports → 误 (这样的省略代表前半句和後半句的主词相同都是 I，但 I 是人，人是不会下雨的)

第一和第二位外国网友说的也对 (不过第一位第二句里面的 no 要改成 not)，第三位网友多了一个 so，或反过来说开头 It 後面少了一个 is。分词构句毕竟不是平常讲话会用的句构，也难怪他们会没想到。
