这个问题我早就注意到了，觉得这是一个“问题”，也曾试图联系湖南省考试院，但未联系上。眼看问题马上就要过期了，所以加了个晚班，查了些资料，整理如下，供大家参考：

▲《英语常见语法错误大曝光》(Nigel D. Turton)：

误：Two people stopped and helped mechanging the wheel.

正：Two people stopped and helped mechange the wheel.

正：Two people stopped and helped meto change the wheel.

我们用 help (someone) do 或 to do something （不是doing）。

误：We were helped carry the pianoupstairs by one of our neighbours.

正：We were helped to carry the pianoupstairs by one of our neighbours.

比较：One of our neighours helped uscarry / to carry the piano upstairs.

▲《朗文英语正误用法词典》：

误：“Can I help you looking after theanimals?” he asked her.

正：“Can I help you (to) look afterthe animals?” he asked her.

▲《简明英语惯用法》（葛传椝；上海译文出版社）：

误：Regular exercise will helpimproving your health.

误：Regular exercise will help youimproving your health.

正：Regular exercise will help toimprove your health.

正：Regular exercise will help improveyour health.（原来是美国用法）

正：Regular exercise will help you toimprove your health.

正：Regular exercise will help youimprove your health.（原来是美国用法）

正：Regular exercise will help you inimproving your health.

▲结论：2011 年的湖南高考英语的 Part IV 中的以下句子是值得商榷的：

Some can help studying for tests, explaining a lesson, and doinghomework.

help sb. in doing sth. 的用法肯定是对的。又如：

Your words have helped us a great deal in understanding your people. 你的话大大有助于我们了解贵国的人民。（张道真《英语常用动词用法词典》）

▲至于能否用 help sb. doing sth. 暂缺乏权威例句。

感谢陈根花老师百忙中解析这个问题。值此机会衷心祝愿陈老师，管理员老师及答疑网的所有老师及网友圣诞快乐！关于这个问题我想引用已故英国利兹大学教授，《牛津高阶》前主编霍恩比先生的一句话供大家参考：对于英语学习者来说，在拿不准 help 后是否用 to 时，带上 to  总是不会错的。

谢谢各位老师的热心帮助，非常敬佩各位老师渊博的知识和严谨的态度！各位老师的解答都很好，但系统只允许我选一个最佳答案，比较之下，我就选陈根花老师的了，请其他几位老师谅解！但每位老师的解答也让我大有收获，受益匪浅，谢谢您们！
