- I hope not
[析] 由于初学者对实际英语口语中表达感情意愿的答语不熟悉，如在肯定答语中 I think so I hope so I believe so 是相同的，但在否定句中却常用 I don't think so 但I don't believe so 和 I don't hope so 则意为：我不信此事和我不希望此事发生。而 I believe not 和 I hope not 则为：我想可能不会发生吧!
[误] - Is anybody there?
- No， Bob and Tom have asked for leave
[正] - Is everybody there?考试用书
- No， Bob and Tom have asked for leave
[析] 许多学生在写作和选择答语或问句时总要语法在前，而不是习惯用语在先。所以总是要拘泥疑问句中的不定代词，用 anybody。 但是Is anybody there? 在英语中为：这里有人吗?而Is everybody there?为：全都到齐了吗?所以首先要考虑的是其答语。 No， Bob and Tom have asked for leave
