improve 后接 do 还是 doing？

在英语学习中，很多同学会疑惑：improve 后面到底应该接 do（即不定式）还是 doing（即动名词）？本文将为你详细解答。

一、基本结论

动词 improve 通常不直接接另一个动词作宾语。 它一般用于以下结构：

• improve + 名词/代词：表示“改善某事”
  例如：She wants to improve her English.
• improve + by + doing：表示“通过做某事来改善”
  例如：You can improve your writing by practicing every day.
• improve + in + 领域：表示“在某方面进步”
  例如：He has improved in math this semester.

二、为什么不能说 “improve to do” 或 “improve doing”？

Improve 是一个及物动词，但它**不接动词不定式（to do）或动名词（doing）作直接宾语**。也就是说，下面这些句子是错误的：

• ❌ I want to improve to speak English. （错误）
• ❌ She improved speaking faster. （错误）

正确表达应为：

• ✅ I want to improve my spoken English.
• ✅ She improved her speaking speed.
• ✅ She improved by speaking faster.

三、常见正确句型总结

• improve + 名词：improve skills, improve health, improve performance
• improve + one's + 名词：improve your memory, improve his attitude
• improve by + doing：improve by reading more, improve by listening carefully
• improve in + 领域：improve in grammar, improve in pronunciation

四、小贴士

如果你想表达“提高做某事的能力”，不要直接在 improve 后加动词，而是把动作转化为名词形式（如 speaking, writing, listening）或使用 by + doing 结构。
