为什么there is no such thing as 后面有的有一个a而有的没有a
例如there is no such thing as power without restraint和There is no such thing as an unbiased observation
there is no such thing as standard Enlish,这句的eglish是可数啊！
答
取决于加的名词是不是可数
答
such thing 是固定用法 thing 在这里是特殊名词
答
There is no such thing可以看作固定用法,
as后面接的是there的实意,
例如：There is no such thing as a perfect human.
也就是说(a perfect human) is no such thing.
答
根据there is，is是单数，要用thing
