此题答案选D，注意两点：一是 devote ... to ... 是固定搭配，意为"把......贡献给......"；二是其中的 to 是介词，不是不定式符号，后接动词时要用动名词。
2. He knows nothing about it, so he can't help _______ any of your work.
A. doingB. to do
C. being doingD. to be done
【陷阱】容易误选A，根据 can't help doing sth 这一结构推出。
【分析】其实答案应选B。比拟以下结构：
can't help to do sth = 不能帮助做某事
can't help doing sth = 禁不住做某事，情不自禁地做某事
又如下面一题，答案也是 B：
She can't help ____ the house because she's busy making a cake.
A cleaningB. to clean
C. cleanedD. being cleaned
再请看以下试题：
While shopping, people sometimes can't help _____ into buying something they don't really need.
A. to persuadeB. persuading
C. being persuadedD. be persuaded
此题应选C，句中的 can't help 意为"禁不住"〔注意根据句意用被动形式〕。
3. All her time _______ experiments, she has no time for films.
A. devoted to do B. devoted to doing
C. devoting to doing D. is devoted to doing

【陷阱】几个干扰项均有可能误选。
【分析】此题最优答案为B。现分析如下：
(1) devote 意为"致力于，献身于"，主要用 devote...to...或be devoted to，其中的to 是介词，不是不定式符号，故后接动词时要用动名词，不用不定式。
(2) 选A错误：假如将 do 改为 doing 如此可以。
(3) 选B正确：all her time devoted to doing experiments为独立主格结构，用作状语。
(4) 选C错误：因为all her time 与 devote 为被动关系，故应将devoting改为devoted。
(5) 选D错误：假如单独看 All her time is devoted to doing experiments，此句并没有错，但问题是逗号前后两个简单句没有必要的连接方式，所以从整体上看仍不对，假假如在后一句的句首加上and或so，如此可选D，或将D将中的is 改为 being也可选它。
请做以下类似题〔答案均选A〕：
