白勇语法第５章语法第３练习题，高手帮助

gedn01

Prompted by new evidence that the health risk posed by radon gas is far more serious than was previously thought,property owners are being advised by authorities to test all dwellings below the third floor for radon gas to make repairs as needed.

a.原文

c.authorities are advising property owers to

答案选ｃ。我想如果这里要选ａ的话，题　目是否要变成Been prompted by new evidence.....

我又在想，advise有没有这种用法are being advised （by authorities） to

译成ＸＸ人被专家建议作某事。

gedn01

有人吗

advise 用作上述被动语态，是错的，白勇前面的语法要点中有提到

liuxy1234

a之所以不对，是因为主句的主语property owners不是前面分词状语从句的逻辑主语。而且过去分词作状语放在句首，been是省略的。

斯巴达

A 所以错  因为,are being advised   这个结构书面语永远错
