I have some difficulty in pronouncing some of the words in English.为什么不用difficulties?

此句中，difficulty作不可数名词,前面不加不定冠词也不能改为复数形式,这里笼统地指困难,费力。
此外difficulty指具体的难事时,是可数名词，才用复数形式。

不要以为句中有some这个单词，就认为后跟名词复数，要知道some既可以修饰可数名词也可修饰不可数名词

希望我讲的这些，您能听的懂

difficulty做困难的事情时才用复数

句子的difficulty为不可数名词，所以不用difficulties

应该是difficulties
