Help sb （in）doing是否是正确用法？（附有例题）

Malimalihonmia

In human hearing, subtle differences in how the two ears hear a given sound help the listener determine the qualities of that sound.

• in how the two ears hear a given sound help the listener determine  
• Bin the two ears hearing a given sound help the listener in determining  
• Cin how a sound is heard by the two ears helps the listener determine  
• Dbetween how the two ears hear a given sound helps the listener in determining  
• Ebetween how a sound is heard by the two ears help the listener in determining  
  这道题正确答案是A但我认为B也是对的，而且意思更符合逻辑PS. 求大神科普，人的两只耳朵听声音的方式真的不一样吗？

b 表达的意思是 differences in the two ears，两个耳朵的不同之处；a 表达的是两个耳朵如何听声音的不同方式。b把原有的句子意思改变了，所以不错。a更好。

嗯，还有就是要注意help做名词的时候，只能用in doing：例题详见OG16 第37题

我觉得用排除法可能更好，
根据主谓一致，有helps的干掉
E between by 很别扭，干掉
至于B选项感觉意思变了，说的是两耳有区别，且 hearing a given sound帮助了听者决定.....
A也就是原句的意思是两耳在听到同一声音的不同帮助了听者决定.....所以B干掉
另外HELP
正确：  He HELPS RAKE the leaves.
He HELPS TO RAKE the leaves.
He HELPS me RAKE the leaves.
He HELPS me TO RAKE the leaves.
His HELP IN RAKING the leaves has been welcome.
错误：He HELPS me IN RAKING the leaves.
I need him AS HELP TO RAKE the leaves.
以上是HELP的用法，应该是只有做名词的时候后面跟doing
然后不建议死记硬背语法点，一般的题通过排除法都可以干掉
