定义 / 说明
有些动词后常接 to + verb。在本级别，重点包括 want、need、hope、plan 和 decide。这种模式下，第二个动词不随人称或时态变化。比如说 She wants to leave，不是 She wants leaves。把“动词 + 固定搭配”整体记忆，能更快说出正确句子。
关键规则
- 用 want + to + verb：I want to leave.
- 用 need + to + verb：We need to talk.
- 用 decide + to + verb：They decided to stay.
- to 后动词用原形。
- 把该结构作为动词的一部分来记。
例句
- I want to leave. - 我想离开。
- They decided to stay. - 他们决定留下。
- We need to talk. - 我们需要谈谈。
- She plans to study abroad. - 她计划出国学习。
- He hopes to find a new job. - 他希望找到新工作。
常见错误
- ❌ I want leave. -> ✅ I want to leave.
- ❌ They decided staying. -> ✅ They decided to stay.
- ❌ We need talk. -> ✅ We need to talk.
