他们认为用英语怎么说高级

"高级"在英语中通常被翻译为 "advanced". 这个词源自拉丁语"ad"和"vanced"的组合，意思是"向前"或"提前"。在形容词的用法中，"advanced"通常用来形容一个东西已经发展到高度成熟或先进的程度。

例如：

"This is an advanced course for students who have already studied the basics." (这是一门高级课程，适合已经学过基础知识的学生。)
"The company's technology is considered advanced for its industry." (这家公司的技术在行业中被认为是高级的。)
"The patient's cancer has advanced to a stage that is difficult to treat." (病人的癌症已经发展到难以治疗的阶段。)
