做某事有困难英语怎么说八下

1. have difficulty (in) doing sth

（介词 in 可省略，后接动名词）

例句：I have difficulty (in) understanding spoken English.

（我在理解英语口语上有困难）

2. have trouble (in) doing sth

（用法同上，trouble 为不可数名词）

例句：She has trouble solving math problems.

（她在解数学题方面有困难）

语法细节：

He has difficulty reading *all words.

They don’t have trouble finishing homework.

There is some difficulty in passing the exam.

同义替换（八年级常见）：

I find it difficult to memorize long sentences.

He struggles with writing essays.

易错点提醒：

1. 不可数名词：difficulty / trouble 不加复数

❌ I have difficulties in... → ✅ I have difficulty in...

2. 固定搭配：后接动名词（doing），不能用不定式

❌ have difficulty to do → ✅ have difficulty doing

建议结合课本例句（如人教版 Unit 1-3 单元相关语法）进行练习，会更贴合考试要求。
