Review:动词不定式作宾语
定义：不定式直接跟在及物动词后，作动词的“动作对象”（宾语）。
结构：主语 + 谓语（及物动词） + to do（宾语）
eg:
He plans to ride a shared bike to school.
They need to download the learning app.

什么是“宾语补足语”
已知结构（不定式作宾语） 新结构
I decide to explore digital life. The teacher asks us to explore digital life.
We hope to use digital payment. The shopkeeper allows us to use digital payment.
1. 新句子中，“us”是什么成分？
2.“to explore/to use”在说明谁的动作？
定义：补充说明“宾语”的动作、状态或身份的成分，让句子意思更完整。
核心逻辑：宾补是“宾语”发出的动作（如上述句子中，“to explore”是“us”的动作，“to use”是“us”的动作）。

宾语补足语：
放在宾语之后，补充说明宾语 “做什么” 或
“怎么样” ，使句意完整。
信息断裂
I want you.
你想让我做什么？句意不完整。
信息自洽
I want you to be happy.
“to be happy”补充说明“你”要怎么样，句子意义完整。
什么是“宾语补足语”
For example:

宾语？ 宾补？
宾语: her roommate
宾补: to turn down the music
宾语: the panda
宾补: to be its symbol
在“动词 + 宾语 + to do”结构中，动词不定式 to do 充当宾语补足语，对宾语进行补充说明。

宾补结构黄金公式
主语 (S) + 谓语 (V) + 宾语 (O) + 宾语补足语 (OC)
I（主语） asked（谓语） the shopkeeper（宾语） to show the QR code（宾补）.
The technology（主语） lets（谓语） me（宾语） live a more convenient life（宾补）.
黄金判断法则：宾语与宾补之间必须能构成“主谓关系”。
什么是“主谓关系”？

黄金判断法则：主谓关系
主语 (S) + 谓语 (V) + 宾语 (O) + 宾语补足语 (OC)
谁“作为标志”？
当宾语和其后的不定式在逻辑上构成“主谓关系”时，该不定式就是宾语补足语。
谁“关音乐”？
her roommate

help
help双规：to可省可留
Help 后接 to do，正式文体中保留 to，更显礼貌。
Help 后接 do，口语或非正式文体中省略 to，更简洁。
核心规则：help 后的 to 可省可不省，意思不变。
eg. Can you help me (to) carry this box

区分：宾语 (O) vs 宾补 (OC)
A: I hope to see you.
B: I want you to come.
“to see you” 是 “hope” 的宾语，
动作由主语 “I” 发出。
“you” 是宾语，“to come” 是宾补，动作由宾语 “you” 发出。
区分秘诀：看不定式的逻辑主语是谁？
是主语，就是宾语 (O)；
是宾语，就是宾补 (OC)。
