"have trouble doing" 是英语中表达“做某事存在困难/麻烦”的常用短语,强调执行某个动作时遇到阻碍或难以完成。
完整形式为 "have trouble (in) doing sth.",其中:
in 是介词,可省略(口语和书面语中均常见);
后面必须接动名词(doing),不能接不定式(to do)(易错点)。
人作主语(最常见):表示“某人做某事有困难”;
物作主语(较少见,但合理):表示“某物运行/操作时存在问题”。
1、 人作主语(日常场景):
I have trouble (in) remembering people's names.
(我记人名有困难。)
Do you have trouble (in) understanding this math problem?
(你理解这道数学题有困难吗?)

与 "have trouble doing" 意思相近、可替换的表达:
have difficulty (in) doing sth.(更正式,强调“困难程度”);
have a hard time (in) doing sth.(更口语化,强调“费劲”)。
总结:"have trouble doing" 是简洁表达“做某事有阻碍”的结构,关键是记住接动名词、in可省,主语可为人或物。
