17.一些广告可能是很有用是真的.It's ture that some advertisements may be quite useful..分析 It's ture that some advertisements may be quite useful.
解答 答案:It's ture that some advertisements may be quite useful.这里是说客观事实用一般现在时,表示某事是真的,我们用it作为形式主语,that从句做真正主语,构成It's ture that,从句主语some advertisements 一些广告,可能may be,形容词useful有用的,用副词quite"相当"来修饰useful,故答案是It's ture that some advertisements may be quite useful.
