C. Have D. Having
23. When __a__ help, one often says “Thank you” or “It’s very kind of you”.（2005福建高考）
A. offering B. to offer
30
DHaving
动名词做主语
前半句的作用是在讲述一个事实，描述一个情况，没必要B完成时
23offered
one 是主句主语，一个人说谢谢，你真好，那么他肯定是被提供帮助的，所以AB肯定不对咯
When _______ (offer) help, one often says,“Can I help you?”or“What can I do for you?”
这里就用A了，不是吗
第一个选D。
C错在，如果用have,则Have the answer ready本身就是一个完整的句子，句子作主语时前边必须加一个that,不能省略。即如果是That have the answers ready will be of great help.那就对了。用to have或者having都是对的（即不定式作主语或动名词作主语）。从上下文看，是在向读者提建议，所以用一般时就可以，没必要用完成时。
第二个应该选offered或者being offered。
A不对。offer的主语就是one,当这个one说“Thank you” or “It’s very kind of you”时，显然他是被帮助的那个，所以要用被动语态。
