who可把gerunds,bare infinitives和ｔｏ－infinitives混合一起？我想測試下自己！！！

好，現在就給你一句：
Peter wants to help us improve our working condition.
to help是to infinitive
而　improve是bare infinitive
最後working condition的working是gerund
三樣東西同時出現，一句句子：其實這句最特別的字是help，因為help之後可以用to infinitive，或gerund，或bare infinitive
如：help us improving...
　　help us to improve...

樓上朋友，大家研究一下：你的句子的help並非bare infinitive，而是用了省略法，將to省略了，全句可寫成：People like playing computer games to amuse themselves and (to) help building up their IQ. (括弧裏的to可以省略）

People like playing computer games to amuse themselves and help building up their
IQ.


PLAYING-- gerund
BUILDING --gerund
TO AMUSE --infinitive
HELP--bare infinitive

Hi, hahatse, I do not see any difference for IMPROVE in your sentence, and HELP in my sentenceas TO can be omitted in both sentences. Their usages are the same. Please explainif you have time.
