need to do和need do有什么区别

如题所述

1. "need to do" 中的 "need" 是情态动词,用于表达义务或必要性。在否定句中,我们使用 "don't/doesn't need to do";在疑问句中,我们使用 "do/does sb. need to do"。
2. "need do" 和 "need to do" 的意思相同,但是 "need" 在这里作为行为动词,需要与助动词 "do" 结合使用。在否定句中,我们说 "needn't do";在疑问句中,我们说 "need sb. do"。
3. "need to do" 的用法示例:
- "Give it directly to him; there is no need to do it through me."(你直接给他就好,没必要通过我来做。)
- "All you need to do is gently agitate the water with a finger or paintbrush."(你只需要用手指或刷子轻轻搅动水。)
- "We need to do something about the sag."(我们需要解决下沉的问题。)
- "They also give you the tools you need to do all of this."(它们还提供了完成所有这些工作所需的工具。)
- "So what do I need to do to dynamically discover and invoke the service?"(那么我需要做什么才能动态地发现并调用这个服务?)
4. "need do" 的用法示例:
- "No, you just need do put down a small deposit to hold your reservation."(不用,你只需要交少量押金来保留你的预订。)
- "If I wanted to recover individual files from an internal snapshot, all I need do is change directory to the appropriate snapshot location and copy the files manually using the cp command."(如果我想从内部快照中恢复单个文件,我只需要将目录更改为适当的快照位置,然后使用 cp 命令手动复制文件。)
