每日一词学英语(16): take with a pinch of salt

BBC Learning English网站有一个栏目叫“6 Minute English”，每星期出一期节目。5月7号这期讲的是Horoscopes and astrology。其中Kate说：

Well, astrology and horoscopes are very popular here in the UK, even though they are often taken with a pinch of salt. To take something with 'a pinch of salt', means that we don't believe something to be entirely accurate or true.
占星和星象在英国十分流行，虽然并没多少人真把它当回事。

Take with a pinch of salt (British & Australian)也可以说，take with a grain of salt (American & Australian)。
Examples:
1) You have to take everything she says with a pinch of salt. She has a tendency to exaggerate.
2) It's interesting to read the reports in the newspapers, but I tend to take them with a grain of salt.
