英语语法问题
It's lucky for someone to sit around with nothing to do whlie I do a a lot of work.
这句话的主语是to sit around with nothing to do
It's lucky for someone,sitting aroud with nothing to do whlie I do a lot of work.
这句话用sitting around with nothing to do修饰someone对吧?但是不就没主语了吗?
但是 sitting aroud with nothing to do 能做形式主语吗？而且前面还有一个逗号~这个句型不是固定的 It's lucky for sb to do

Answer 1

这两个句子都是用it 作形式主语,真正的主语分别是后面的不定式和现在分词,也就是说“坐在旁边无事可做”这件事情,是句子的主语.而someone叫后面不定式或现在分词的逻辑主语.整个句子它要表达的是“这件事情 是 幸运的”.
sitting around with nothing to do是句子真正的主语,只是因为较长,所以放到了后面,用it 作形式主语.跟逗号没有关系的.这个句式可以说是it's lucky for sb.to do 但是 你要细分析成分的话 就是我之前说的.
