我总结了 for you to do 的10 种类型，以及我个人的分析。句1,2  针对网友的问题。

1. This decision is for you to make.（反射不定式，不定式复合结构作表语）

= You are to make this decision.

= You should make this decision.

2. It is for you to make the decision.（不定式作真正主语）

= It depends on you to make the decision.

= It is up to you to make the decision.

3. It is easy for you to make the decision. （不定式复合结构作真正主语）

4. This decision is easy for you to make. （反射不定式，不定式复合结构作形容词补足语）

5. This decision is easy enough for you to make. （反射不定式，不定式复合结构作结果状语）

6. We are waiting for you to make the decision. （不定式复合结构，作目的状语）

7. We are eager for you to make the decision. （不定式复合结构，作形容词补足语）

8. There is a decision for you to make. （反射不定式，不定式复合结构作定语）

9. We made a decision for you to resign from office. （不定式复合结构作定语，表示同位关系）

10. The decision is for you to resign from office. （不定式复合结构作表语，说明主语的内容）

几个两难选择的结构：

① It is for you to make.

【说明】结构同句1。反射不定式，因为make 是及物动词，it 是代词。

② It is for you to decide.

【说明】结构同句1，反射不定式，decide是及物动词，it 是代词；

结构同句2，it 是形式主语，不定式作真正主语，decide是不及物动词。

③ This is for you to decide.

【说明】结构同句1。反射不定式，decide是及物动词。this 是其逻辑宾语。
