问 so+adj.+be+主语RT 是否有这样的结构,能否详细讲解说明?看到的是这样一个句子：So numerous were the inventions devised to lessen the drudgery of washing clothes that the origin of the washing machine is unclear. 英语
网友回答
【答案】 这是一个so...that句型(如此...以至于)的倒装强调说法.
不倒装的句子是这样的：
The inventions devised to lessen the drudgery of washing clothes WERE SO numerous THAT the origin of the washing machine is unclear.
为减轻洗衣服的重担而发明出来的东西如此之多,以至于无法搞清洗衣机的起源.
