It is said that…中的that从句如果用一般现在时是很正常的。如:
It is said that he’s got married. 听说他结婚了。
It is said that honesty is the best policy. 常言说诚实是上策。
It is said that thirteen is an unlucky number. 据说13是一个不吉利的数字。
It is said that there is plenty of oil off our coast. 据说我们近海有大量石油。
It is said that the boss is sour toward his employees. 据说这个老板对他的雇员很刻薄。
但如果后面的 that 从句是一般过去时呢?还可以用 it is said…吗?还是要用 it was said…呢?
It is said that…后的从句可以用过去时态,例如:
It is said that he was introduced to the king by a wealthy cousin. 据说他由一个富有的表兄引荐给了国王。(《麦克米伦高阶英汉双解词典》p.1849)
It is said (that) he hit the jackpot in South America. 人们传言他在南美赚了一大笔钱。(《外研社英汉多功能词典》p.1865)
